Waste gas treatment equipment manufacturers, mainly using a variety of technology, through the recovery or removal of emissions of harmful components and harmful substances to protect the environment, purify the air to achieve the ultimate goal of an environmental protection equipment.
Waste gas treatment equipment is mainly divided into the following:
1. Absorption equipment
VOCs were absorbed by low volatile or non-volatile solvents, and then separated by the difference of physical properties between VOCs and absorbents. The bottom of the self-absorption tower containing VOCs enters the tower and contacts the absorbent from the top of the tower during the rising process. The purified gas is discharged from the top of the tower. After absorbing VOCs through the heat exchanger, the absorbent enters the top of the stripper and desorbs when the temperature is higher than the absorption temperature or the pressure is lower than the absorption pressure. After desorption, the absorber is condensed through the solvent condenser and then returned to the absorber. The desorbed VOCs are separated from the stripper by a condenser and a gas-liquid separator and recycled. This process is suitable for gas purification with high VOCs concentration and low temperature, and other conditions need to be adjusted accordingly. Waste gas treatment equipment.
2. Adsorption equipment
When a porous solid is used to treat a fluid mixture, a component or some component of the fluid can be absorbed onto the surface and concentrated on it. This phenomenon is called adsorption. When adsorbing waste gas, the adsorbed objects are gaseous pollutants and gas-solid adsorption. The adsorbed gas components are called adsorbents, and porous solids are called adsorbents.
A part of the adsorbate adsorbed on the solid surface can be detached from the adsorbent surface. However, when the adsorption is carried out for a period of time, due to the concentration of the adsorbate on the surface, the adsorption capacity of the adsorbent obviously decreases and the requirement of adsorption purification is required. At this time, some measures should be taken to desorb the adsorbate adsorbed on the adsorbent to treat the adsorption capacity of the equipment with co-exhaust gas. This process is called the regeneration of the adsorbent. Exhaust gas treatment equipment manufacturers explain the solid so in the actual adsorption project, it is precisely the use of adsorption and re-adsorption cycle process, to remove pollutants from the exhaust gas and recover useful components from the exhaust gas.
