UV photolysis waste gas processor

UV photolysis waste gas treatment equipment mainly uses different process technologies to reduce harmful components in exhaust emissions by recycling or removing them, achieving environmental protection and air purification. It is an environmentally friendly equipment that prevents our environment from being polluted. Nowadays, most industrial plants are equipped with exhaust gas treatment equipment. On the one hand, it is mandatory by the state, and on the other hand, the government provides subsidies for exhaust gas treatment equipment. Enterprises only need to spend a small amount of money on it. Therefore, in recent years, the promotion of exhaust gas treatment equipment in China has been rapid. The widely used exhaust gas treatment equipment is UV photolysis treatment equipment. Below, the editor will tell you its characteristics?

The main principle of UV photolysis waste gas treatment method is to decompose waste gas molecules through high-energy UV rays, rapidly oxidize harmless substances, and thus achieve the purpose of purification. And different treatments can be designed according to different emission levels, which will avoid resource waste and adopt appropriate treatment equipment based on the current situation of the enterprise's exhaust emissions.

In fact, the main reasons why exhaust gas treatment is difficult to treat are the complex composition of exhaust gas, fast diffusion of exhaust gas, large emission volume, and difficulty in thorough treatment. It is still not honorable to meet the national emission standards. After the introduction of UV photolysis exhaust gas treatment method, China's exhaust gas treatment industry has undergone a qualitative change, because the purification efficiency of UV photolysis can reach more than 98%, and the area occupied is not large, and the cost of later operation and maintenance is very low. Moreover, UV photocatalytic waste gas treatment is not affected by external factors such as temperature, air humidity, wind direction, etc. It only requires controlling the switch of the equipment, almost no need for human supervision, stable and reliable equipment operation, and is suitable for most waste gas treatment. It is the main method of waste gas treatment in China.

Adsorption equipment

After the solid surface adsorbs the adsorbate, a portion of the adsorbed adsorbate can detach from the adsorbent surface, which is now attached. After a period of adsorption, due to the concentration of surface adsorbates, their adsorption capacity significantly decreases and the requirements for adsorption purification are met. At this time, certain measures need to be taken to desorb the adsorbates already adsorbed on the adsorbent to enhance its adsorption capacity. This process is called adsorbent regeneration. Therefore, in practical adsorption engineering, it is the cycle of adsorption regeneration and repeated adsorption that is used to remove pollutants from the exhaust gas and recover useful components from the exhaust gas. When treating fluid mixtures with porous solid materials, a certain component or components in the fluid can be adsorbed onto the surface and concentrated on it, which is called adsorption. When adsorbing and treating exhaust gas, the adsorbed object is gaseous pollutants, gas-solid adsorption. The adsorbed gas component is called adsorbate, and the porous solid material is called adsorbent.

Absorption equipment

The extracted VOCs gas passes through the condenser and gas-liquid separator before leaving the stripping tower as relatively pure VOCs gas, which is then recycled and reused. This process is suitable for gas purification with high VOCs concentration and low temperature, and requires corresponding process adjustments in other situations. The absorption method uses low volatile or non-volatile solvents to absorb VOCs, and then separates them based on the differences in physical properties between VOCs and absorbents. The gas containing VOCs enters the absorption tower from the bottom and comes into contact with the absorbent from the top of the tower in reverse flow during the upward process. The purified gas is discharged from the top of the tower. After absorbing VOCs, the absorbent enters the top of the stripping tower through a heat exchanger and desorbs under conditions where the temperature is higher than the absorption temperature or the pressure is lower than the absorption pressure. The desorbed absorbent is condensed by a solvent condenser and returned to the absorption tower.
