Background
The waste gas treatment equipment mainly refers to an environment-friendly equipment which protects the environment and purifies the air by recovering or removing and reducing harmful components of the discharged tail gas by using different process technologies, so that the environment is not polluted. The absorption method adopts a low-volatility or non-volatile solvent to absorb the VOCs, and then separates the VOCs by utilizing the difference of physical properties of the VOCs and the absorbent. The gas containing VOCs enters the tower from the bottom of the absorption tower and is in countercurrent contact with the absorbent from the top of the tower in the ascending process, and the purified gas is discharged from the top of the tower. The absorbent absorbing the VOCs passes through the heat exchanger and enters the top of the stripping tower to be desorbed under the condition that 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 then returns to the absorption tower. And the desorbed VOCs gas passes through a condenser and a gas-liquid separator and then leaves the stripping tower as relatively pure VOCs gas to be recycled. The process is suitable for gas purification with higher concentration of VOCs and lower temperature.
