Pressure swing adsorption oxygen production equipment

Process principled

Pressure swing adsorption oxygen production equipment (also known as PSA oxygen production equipment) uses PSA special molecular sieve to selectively adsorb impurities such as nitrogen, carbon dioxide, and water in the air under normal temperature and pressure conditions to obtain higher purity oxygen (93 %±2).

Since the pressure swing adsorption oxygen production equipment entered industrialization, the technology has developed rapidly. Because of its price-performance ratio in the low-to-medium output range and the occasions where the purity requirements are not high, it has strong competitiveness, so it is widely used in steel-making fluxing. , Blast furnace oxygen enrichment, pulp bleaching, glass furnace, wastewater treatment, and other fields.

Domestic research on this technology started earlier, but the development has been relatively slow for a long period of time. Since entering the 1990s, the superiority of PSA oxygen generation equipment has been gradually recognized by the Chinese people. In recent years, various process equipment has been put into production one after another. Click here to learn about small oxygen generators for home use.

Process Description

The oxygen production system is mainly composed of an air compressor, air cooler, an air buffer tank, a switching valve, an adsorber and an oxygen balance tank. After the raw material air passes through the suction port filter to remove the dust particles, it is pressurized to 3~4barg by the air compressor and enters one of the adsorbers.

The adsorber is filled with adsorbent, in which moisture, carbon dioxide, and a small number of other gas components are adsorbed by the activated alumina at the bottom of the adsorber, and then nitrogen is adsorbed by the zeolite molecular sieve filled on the upper part of the activated alumina.

The oxygen (including argon) is a non-adsorbed component and is discharged from the top outlet of the adsorber as product gas to the oxygen balance tank. When the adsorber is adsorbed to a certain level, the adsorbent in it will reach saturation. At this time, the adsorbent is vented through the switching valve, and the adsorbed water, carbon dioxide, nitrogen, and a small number of other gas components are discharged to the atmosphere, and the adsorbent is regenerated.

Each adsorber of PSA performs the following steps alternately:
---Adsorption---Desorption---Stamping
The above three basic process steps are automatically controlled by PLC and switching valve system.

Application field

Metallurgical electric arc furnace steelmaking, blast furnace iron making and oxygen enrichment, shaft furnace oxygen-enriched combustion, non-ferrous smelting industry, lead smelting, copper smelting, zinc smelting, aluminum smelting, various furnaces, oxygen-enriching environmental protection industry drinking water treatment, wastewater treatment, pulp bleaching, Waste biochemical treatment, various oxidation reactions in the chemical industry, ozone production, coal gasification and other industrial fermentation, cutting, glass furnaces, air conditioners, garbage incineration, oxygen inhalation bars in the medical industry, oxygen therapy, sports health care, aquaculture, freshwater aquaculture.

PSA oxygen generator features

1. The unit is simple, and the moving equipment is only an air compressor and a cooler. 2. The requirement for molecular sieve is relatively low, and with the same oxygen production equipment, the molecular sieve consumption is small. 3. The equipment is small in size, so its cost is relatively low. 4. The requirements for the degree of automation of the entire equipment are relatively low. The air compressor, freeze dryer/condenser can be started and stopped separately from the oxygen generator or can be linked to control.

Short supply of disposable protective gloves

Due to the outbreak of the epidemic this year, the demand for disposable protective gloves on the market has also increased sharply. As a disposable glove manufacturer, we have high-quality and low-cost disposable gloves for everyone to choose from. Disposable gloves can be divided into nitrile gloves, PVC gloves and latex gloves according to their materials. Next, briefly talk about their differences, uses, and materials. Summer’s WhatsApp: +86 138 3856 5351

The raw material is different

1. Nitrile gloves: The material is NBR, a synthetic rubber, and the main components are acrylonitrile and butadiene;

2. PVC gloves: the material is polyvinyl chloride;

3. Latex gloves: The material is natural latex (NR).

The characteristics are different

1. Nitrile gloves: Nitrile inspection gloves can be worn on both hands, made of 100% nitrile latex, no protein, effectively avoiding protein allergies; the main performance is puncture resistance, oil resistance and solvent resistance; hemp-like surface treatment, avoid It is easy to wear after the powder-free treatment, and effectively avoids skin allergies caused by powder.

2. PVC gloves: resistant to weak acid and weak alkali; low ion content; good flexibility and touch; suitable for semiconductor, liquid crystal and hard disk production processes.

3. Latex gloves: latex gloves have abrasion resistance, puncture resistance; resistance to acids and alkalis, grease, fuel and a variety of solvents, etc.; have a wide range of chemical resistance, good oil resistance; latex gloves feature unique fingertip texture design , It greatly enhances the grip and effectively prevents slippage.

different uses

1. Nitrile gloves mainly used in medical, pharmaceutical, sanitation, beauty salon and food processing industries. Nitrile gloves can be divided into two types: powder-free and powder-free. The length of nitrile gloves is 23cm and 30cm; the thickness is 0.08~0.09mm, and the color is mainly blue. The main product packaging is 100pcs per box, and the specifications are XS, S, M, L, XL.

2. PVC gloves: suitable for clean rooms, hard disk manufacturing, precision optics, optical electronics, LCD/DVD liquid crystal manufacturing, biomedicine, precision instruments, PCB printing and other industries. It is widely used in labor protection and household hygiene in hygiene inspection, food industry, chemical industry, electronics industry, pharmaceutical industry, paint and coating industry, printing and dyeing industry, agriculture, forestry, animal husbandry and other industries.

3. Latex gloves: can be used as household, industrial, medical, beauty and other industries. It is suitable for automobile latex gloves manufacturing, battery manufacturing; glass fiber reinforced plastic industry, aircraft assembly; aerospace field; environmental cleaning and cleaning.

In order to prevent the gloves from slipping and improve the comfort of use, the palms of the cut-resistant gloves are dipped. According to the different dipping gels, they are divided into three types: latex, nitrile and polyurethane. Among them, polyurethane gloves have a thinner gel, which is generally used in gardening and electronic industries with relatively high sensitivity requirements; latex gloves and nitrile gloves have relatively thick gels, latex gloves have better anti-slip performance, and nitrile gloves have better oil stain resistance. Used in mechanical processing, logistics handling, oil depot operations, etc.

Work overtime to produce epidemic prevention product for India

 During International Labor Day, the epidemic in India has continued to worsen. Countries around the world are paying close attention to the epidemic in India. In particular, as a close neighbor, China has been doing its utmost to support India. Chinese oxygen generator manufacturers work overtime on Labor Day to produce oxygen generators and ship them to India.

Sun Weidong, the Chinese ambassador to India, said that employees of a Chinese manufacturer of oxygen concentrators worked overtime during the May 1st holiday to produce and pack machines for shipment to India. Sun Weidong posted on Twitter the day before yesterday (May 2) that the batch of oxygen generators will be shipped to India soon. He also attached a video of employees packing the oxygen concentrator machines to the tweet.

China provides help to India

Since this round of the epidemic in India worsened, China's attitude towards the epidemic in India has attracted considerable attention. Chinese President Xi Jinping sent a message of condolences to Indian Prime Minister Modi last Friday, expressing his willingness to strengthen cooperation with India in the fight against the epidemic and provide support and assistance to the Indian side. On the same day, Chinese Foreign Minister Wang Yi also had a phone conversation with Indian Foreign Minister Su Jaishan, saying that he would provide assistance to India. As the ambassador to India, Sun Weidong has also frequently posted messages on China’s support for India on social media in recent days.

In an interview with the Global Times last Friday, Sun Weidong said that China was one of the first countries to offer support and assistance to India and one of the first countries to put actual actions into practice. He also said that many Chinese companies and non-governmental organizations are providing various assistance to India in their own way. Sun Weidong also said that relevant domestic Chinese companies are stepping up the production of orders for at least 40,000 oxygen concentrators submitted by India, and strive to deliver the necessary medical supplies to India as soon as possible.

Emergency production oxygen generator

Sun Weidong said that China will continue to encourage and support Chinese enterprises to accelerate the production and provision of anti-epidemic materials, provide customs clearance and transportation convenience for India's purchase of anti-epidemic materials, and organize anti-epidemic exchanges between health and epidemic prevention experts of the two countries to share the anti-epidemic experience. The next day, he wrote on Twitter that there were 61 cargo flights from China to India in the past two weeks, delivering all kinds of urgently needed medical supplies to India.

In addition, the Chinese Embassy in Sri Lanka announced on Twitter on the 26th of last month that China has airlifted 800 oxygen generators to India and will provide India with an additional 10,000 medical use oxygen generators within a week. The epidemic situation in India continues to worsen, and the spread of the virus is still rapid. According to a Reuters report yesterday, India has had more than 300,000 new cases per day for 12 consecutive days. For China’s support, Jaishan Su expressed his gratitude during the call with Wang Yi.

As a leading manufacturer of oxygen generators in China, YG company has also been working overtime to produce oxygen generators. I hope that people in India and all over the world will stay away from the new crown epidemic as soon as possible.

Why is the epidemic coming back?

The mismatch of the new crown vaccine + the mutation of the virus + the slack prevention and control of the epidemic has led to the fourth wave of upward trend in the overseas new crown epidemic.

With the continuous vaccination of vaccines, the epidemic should gradually recede. But in fact since March 2021, the global new crown epidemic has shown signs of continuous rebound, and the number of new confirmed cases in a single day has once again soared.

In the past five days (April 20-April 24), the number of newly confirmed cases abroad in a single day reached 759 thousand, 787 thousand, 849,000, 1.070 thousand, and 865,000 respectively, compared with February 2021 The daily level of 300,000 to 400,000 new cases has almost doubled, and it has refreshed the previous historical high in December 2020. The WHO also stated at a recent press conference that the current situation is close to the highest infection rate since the outbreak.

The overseas new crown epidemic is experiencing a fourth wave of upward movement (the first wave is in March 2020, the second wave is in July 2020, and the third wave is in December 2020).

Status of the epidemic in India

As the epidemic situation eased at the beginning of the year, epidemic prevention and control measures in various countries have been loosened, especially in populous countries such as Brazil and India. The people's failure to observe the prevention and control measures such as wearing masks and maintaining social distancing, and holding large-scale gatherings caused the epidemic to break out on a large scale again. If you work in airports, railway stations, large supermarkets, hospitals and other places, the intelligent ultraviolet disinfection robot and disinfection door will be your right-hand man in disinfection.

India is the country with the worst epidemic in this round, and it is facing a situation of out of control. In the past 24 hours, there were nearly 400,000 new cases in a single day. There have been more than 300,000 new confirmed cases in a single day for several consecutive days, and it continues to set new highs. The cumulative number of confirmed cases has exceeded 17 million.

Another large-scale outbreak of the epidemic in India is closely related to the previous government’s approval of the opening of the Big Pot Festival. The Big Pot Festival is a very large religious gathering, which also includes bathing in the Ganges River. Almost a million people enter the Ganges every day Participate in religious ceremonies.

In addition, the vaccine progress is slow (the two-dose vaccination rate is less than 2%, and the one-dose vaccination rate is less than 10%. The United States has “stuck the neck” on key raw materials, causing major problems in the local vaccine supply), and the spread of mutant strains (locally) B.1.617 double mutated virus, in recent sampling, India B.1.617 virus has accounted for 70.4%) also objectively aggravated the outbreak of the epidemic in India.

The epidemic situation in India has become out of control. Due to the large number of patients and the shortage of medical resources, many local designated hospitals have even shared the same multifunctional hospital bed for two patients, and there has even been a nationwide oxygen shortage.

Medical oxygen generator exports

At the present, many countries including China rushed to aid India in an emergency. Hundreds of oxygen generators were delivered to it, including large-scale PSA medical oxygen generators. Small medical oxygen generator. Personal household oxygen generators, etc. As a leading manufacturer of oxygen concentrator in China, YG Engineering company is also increasing its production speed, and doing its best to let the Indian people use high-quality and efficient YG oxygen concentrators to resist the disease.

What are the benefits of a household oxygen generator？

With people's pursuit of health and lifestyle, oxygen concentrators are no longer the boring big machines in hospitals. They have been gradually optimized and gradually entered the public's homes. After entering the family, it has turned into a "healthy artifact". In the publicity of many businesses, the oxygen concentrator seems to help solve most of the uncomfortable symptoms encountered daily, and many healthy people have also chosen to inhale oxygen.

According to the survey, many home oxygen concentrators on sale claim that in addition to curing diseases such as chronic lung obstruction and asthma, they also have many health benefits: relieve stress and relieve fatigue; provide oxygen to the skin, which has beauty effects; pregnant women inhale oxygen It can promote the growth and development of babies and other magical effects, but are these true? Today I will give you answers one by one.

What is the best household oxygen generator?

A household oxygen generator is a device that can produce oxygen. It can be used to correct body hypoxia and oxygen therapy. It is characterized by inhaling oxygen directly to increase the oxygen content of the arteries, rather than acting on a certain part of the body to indirectly improve hypoxia. Increase the body's continuous intake of oxygen throughout life.

Is the home oxygen concentrator really a "healthy artifact"?

Some experts pointed out that the oxygen concentrator has a certain effect on people with hypoxia, such as chronic obstructive pulmonary disease, asthma, bronchiectasis, gas poisoning, and other diseases. There is currently no evidence that oxygen can be used to make beauty. Oxygen inhalation is purely conceptual hype because the surface of human skin cannot directly absorb oxygen. Even though pressure oxygen injection, hand massage, etc., oxygen cannot enter the skin.

What are the benefits of a home oxygen concentrator?

The home oxygen concentrator is suitable for family use. The advantages are convenient and simple. It can not only help the hypoxic population but also help the health care problems of middle-aged and elderly people. However, one should pay attention to the purchase of a home oxygen concentrator and choose a medical-grade certificate. The oxygen concentrator is more secure, which is similar to the YG oxygen concentrator.

How to choose a household oxygen generator？

1. When choosing a household oxygen concentrator, you must choose a big brand. A manufacturer with a long-standing brand can guarantee its sustainable development and future maintenance services.

2. Medical device registration certificate. This is also very important. Medical-grade oxygen concentrators are more strictly controlled, and many household oxygen concentrators on the market are actually three-no products.

3. The oxygen concentration output by the household oxygen generator must be greater than 90% in order to maintain a stable output.

4. Be sure to choose an oxygen generator with a noise level of fewer than 45 decibels, otherwise, it will affect rest, especially at night. Click here to know more about PSA oxygen generator. 

How to choose a right drilling rig?

 

How to choose a drilling rig?

You need drilling equipment for various purposes. For example, drilling a well to obtain natural resources (water, oil, geothermal energy, etc.) to build a foundation, drill holes in a mine, and take samples from the ground.

 

It is necessary to determine the purpose of the drilling rig and what kind of terrain it is mainly operated on. Depending on the terrain, you can choose different types of drilling rigs: rotary drilling rigs, percussion drilling rigs, down-the-hole drilling rigs, top hammer drilling rigs (with high hammers), etc.

 

In order to make the best choice, it is important to determine whether the rig is used for core business or occasional use, especially if you are using the latest technology, or a rig that has been available for decades.

 

Security, reliability, and ease of use are also important factors that need to be considered, and there is a direct connection between them. According to the drill machine manufacturer's recommendations, the use of reliable and easy-to-operate drilling rigs can improve user safety.

 

It is also very important to define the type of movement required by the rig. There are crawler-type automatic drilling rigs and truck-mounted or trailer-mounted drilling rigs, which need to be powered by generators or trucks that carry them.

 

Once the type of rig required is determined, the required rig size can be calculated based on the diameter and depth of the hole.

When do you need to drill rig?

Drilling is required in many jobs, such as:

Drilling: used to obtain groundwater or oil.

Geothermal drilling: obtain and extract geothermal energy.

Pile-driving rigs that support buildings on unstable ground: up to 2000 mm in diameter and 70 meters in depth.

Micro pile drilling rigs, especially for drilling holes for reinforcement of existing structures: diameter between 150 and 200 mm, depth within 30 meters.

Blasthole drilling rig in the quarry.

The continuous rotary uses drill cuttings driven by the rotary drill machine to maintain the borehole wall.

Drilling is usually done vertically, but it can also be horizontal or directional, for example for anchoring.

Which type of drilling rig should I choose?

There are two main types of drilling rigs: automatic crawler type and truck-mounted or trailer type.

If you need to move at a low speed on uneven areas or very soft ground, you can choose a crawler drill. The stability of the rig depends on the surface area of the track. Therefore, the wider the crawler, the more stable the drilling rig. But when the track is too wide, when moving, especially when turning, it tends to wear faster and damage the ground. The crawler drilling rig has a travel speed of about 4km/h, so it is more suitable for operations that require little travel.

Truck-mounted or trailer-mounted drilling rigs are not autonomous in mobility or energy. These energy sources may come from transport trucks or independent generators. However, this type of drilling rig is much lower in cost than crawler drilling rigs. Click here to know more.
