Problems solved by technology

In a conventional washing tower, the absorption efficiency of the absorption liquid in the tower decreases after a period of use, and it is necessary to replace the absorption liquid to restore the designed absorption efficiency. The frequency of liquid replacement can keep the treatment efficiency relatively stable, but it will increase the amount of absorption liquid used, and at the same time, the amount of waste absorption liquid will increase, resulting in waste

Abstract

The invention discloses a multistage exhaust gas washing tower. The multistage exhaust gas washing tower comprises a plurality of exhaust gas washing towers which are connected in series, wherein each exhaust gas washing tower comprises a tower body, a water tank, a circulating pump and a shower pipe; the circulating pumps are connected between the water tanks and the shower pipes to form water circulating loops; the tower bodies of the different exhaust gas washing towers are sequentially communicated through an exhaust gas pipeline in the forward direction; the water tanks of the different exhaust gas washing towers are reversely and sequentially communicated through an overflow pipe; an exhaust gas inlet and an absorption liquid discharge hole are formed in the first exhaust gas washing tower in the forward direction; an exhaust gas outlet and an absorption liquid discharge hole are formed in the first exhaust gas washing tower in the reverse direction. The multistage exhaust gas washing tower disclosed by the invention is forming by connecting the plurality of washing towers in series; the exhaust gas flows forwards in the washing towers; the absorption liquid is continuously added to the towers and flows in the towers reversely in series; the exhaust gas is firstly in contact with the absorption liquid with higher primary pollutant concentration, and at last in contact with the cleanest absorption liquid, so as to ensure that the processing efficiency is stable, and a better processing effect can be achieved.

Description

technical field [0001] The application belongs to the technical field of environmental protection, and in particular relates to a multistage waste gas scrubber. Background technique [0002] Exhaust gas scrubber is a commonly used waste gas treatment equipment. It uses the absorption liquid to contact the waste gas, and through mass transfer, the pollutants in the waste gas are intercepted into the absorption liquid to reduce the concentration of pollutants in the waste gas. In a conventional washing tower, the absorption efficiency of the absorption liquid in the tower decreases after a period of use, and it is necessary to replace the absorption liquid to restore the designed absorption efficiency. The frequency of liquid replacement can keep the treatment efficiency relatively stable, but it will increase the use of absorption liquid, and at the same time, the amount of waste absorption liquid will increase, resulting in waste. Contents of the invention [0003] The pu...
