Industrial oxygen equipment is an automated equipment that uses zeolite molecular sieves as adsorbents and uses the principles of pressure adsorption and pressure reduction desorption to adsorb and release oxygen from the air, thereby separating oxygen. . Zeolite molecular sieve is a spherical granular adsorbent that is processed through a special pore processing technology. The surface and interior are covered with micropores. It is white in color. Its pore characteristics enable it to achieve precise kinetic separation. The separation effect of zeolite molecular sieve on gas and gas is based on the slight difference in the kinetic diameter of the two gases. The molecules have a faster diffusion rate in the micropores of the zeolite molecular sieve, and the molecular diffusion rate is slower. The diffusion of water and nitrogen in compressed air is not much different from that of nitrogen. What is finally enriched from the adsorption tower is oxygen molecules.
Pressure swing adsorption oxygen production utilizes the selective adsorption characteristics of zeolite molecular sieves, using a cycle of pressure adsorption and decompression desorption, so that compressed air enters the adsorption tower alternately to achieve air separation, thereby continuously producing high-purity Product Oxygen.
The oxygen generator is based on the principle of pressure swing adsorption and uses high-quality zeolite molecular sieve as the adsorbent to produce oxygen from the air under a certain pressure. The purified and dried compressed air is adsorbed under pressure and desorbed under reduced pressure in the adsorber. Due to the aerodynamic effect, the diffusion rate of nitrogen in the pores of the zeolite molecular sieve is much greater than that of oxygen. Nitrogen is preferentially adsorbed by the zeolite molecular sieve, and oxygen is enriched in the gas phase to form finished oxygen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed nitrogen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system. One tower adsorbs and produces oxygen, and the other tower desorbs and regenerates. The program controller controls the opening and closing of the pneumatic valve, so that the two towers cycle alternately to achieve the purpose of continuous production of high-quality oxygen. The entire system consists of the following components: compressed air purification components, air storage tanks, oxygen and nitrogen separation devices, and oxygen buffer tanks. If cylinders are needed, an oxygen booster and bottle filling device are installed at the end.
Compressed air purification group
The compressed air provided by the air compressor is first passed into the compressed air purification assembly. The compressed air first removes most of the oil, water, and dust through the pipeline filter, and then is freeze-dried. The machine further removes water, the fine filter removes oil, and dust, and is followed by a super-fine filter for deep purification. According to the system working conditions, UEG Gas has specially designed a set of compressed air oil remover to prevent possible trace oil penetration and provide sufficient protection for the molecular sieve. Rigorously designed air purification components ensure the service life of the molecular sieve. The clean air processed by this component can be used as instrument air.
. Air storage tank
The function of the air storage tank is to reduce air flow pulsation, act as a buffer to reduce system pressure fluctuations, and allow compressed air to pass smoothly through the compressed air purification component to fully remove oil and water impurities. , reducing the load on the subsequent oxygen and nitrogen separation device. At the same time, when the adsorption tower switches work, it also provides the oxygen and nitrogen separation device with a large amount of compressed air required for rapid pressure increase in a short time, so that the pressure in the adsorption tower quickly rises to the working pressure, ensuring reliable and stable operation of the equipment. .
Oxygen and nitrogen separation device
There are two adsorption towers equipped with special molecular sieves, B. When the clean compressed air enters the inlet end of the tower and flows to the outlet end through the molecular sieve, it is adsorbed by it, and the product oxygen flows out from the outlet end of the adsorption tower. After a period of time, the molecular sieve adsorption in the tower is saturated. At this time, the tower automatically stops adsorption, and the compressed air flows into Tower B to absorb nitrogen and produce oxygen, and regenerate the tower-joined molecular sieve. The regeneration of molecular sieves is achieved by rapidly lowering the adsorption tower to normal pressure to remove the adsorbed ones. The two towers alternately perform adsorption and regeneration to complete the separation of oxygen and nitrogen and continuously output oxygen. The above processes are controlled by programmable controller (). When the oxygen purity at the outlet end reaches the set value, the program takes effect and the automatic vent valve opens to automatically vent unqualified oxygen to ensure that unqualified oxygen does not flow to the gas point. When the gas is vented, silencer is used to make the noise less than B.
Oxygen buffer tank
The oxygen buffer tank is used to balance the pressure and purity of oxygen separated from the nitrogen and oxygen separation system to ensure a stable continuous supply of oxygen. At the same time, after the adsorption tower switches work, it will recharge part of its own gas into the adsorption tower. On the one hand, it helps to increase the pressure of the adsorption tower, and on the other hand, it also plays a role in protecting the bed. It plays a very important role in the operation of the equipment. Supporting role.
