AI Technical Summary

Technical Problem

When the prior art purifies alkaline waste gas, the particulate impurities contained in the waste gas will react with the spray liquid, resulting in a large amount of foam adhered to the inner wall and filler of the tower, resulting in a failure of the absorption tower and a reduced processing efficiency, and the replacement of the filler is complex and inefficient.

Method used

An alkaline exhaust gas treatment system including an absorption tower, a cyclone separation shell and a filler is designed. The cyclone separation shell is used for gas-solid separation to ensure that the particulate impurities in the exhaust gas are separated and avoided reaction with the spray liquid; the filler is quickly replaced by an inclined filler inlet pipe and a horizontal filler outlet pipe.

Benefits of technology

It effectively solves the foam problem caused by particle impurities in alkaline waste gas, improves the efficiency of waste gas treatment, simplifies the replacement of fillers, and improves the convenience of operation.

Abstract

The alkaline waste gas treatment system comprises an absorption tower, a cyclone separation shell is installed at the bottom of an inner cavity of the absorption tower, a liquid circulation gap is formed between the inner wall of the absorption tower and the cyclone separation shell, and the upper portion of the inner cavity of the absorption tower is filled with filler; a vertically-arranged communicating pipe is fixedly mounted at the top of an inner cavity of the cyclone separation shell, and a hemispherical buffer plate is arranged over the communicating pipe; an inclined filler inlet pipe and a horizontal filler outlet pipe are fixedly mounted on the outer wall of the absorption tower, and operating platforms are arranged below the filler inlet pipe and the filler outlet pipe and are fixedly connected to the outer wall of the absorption tower. The alkaline waste gas treatment system provided by the utility model can effectively solve the problem that a large amount of foams are generated by the reaction of particle impurities contained in waste gas and spray liquid and are adhered to the inner wall of the tower and the filler, ensures the treatment efficiency of the alkaline waste gas, and can realize the quick replacement of the filler.
