Concentrated acid mist purifying device

Abstract

The invention discloses a concentrated acid mist purifying device which is characterized in that eleven serially connected containers are arranged in a cabinet body; high-speed airflow is generated through an air pump to dissolve concentrated acid mist in clear water or alkaline liquid in the eleven containers in sequence. According to the concentrated acid mist purifying device, firstly, the treatment time is prolonged in the clear water, and the clear water can be used for all-directionally cleaning the concentrated acid mist and effectively removing particles, impurities and water-soluble organic matters in the concentrated acid mist, so that the primary purification process is finished; secondly, concentrated acid mist gas passes through the alkaline liquid in a full-bath manner, so that the gas-liquid contact area is greatly enlarged; the full contact reaction is produced, so that the absorption efficiency of the alkaline liquid is improved and the purposes of diluting and neutralizing acidic gas and reducing the acidic gas concentration are achieved; thirdly, the acid mist gas enters the clear water containers to be cleaned, so that the acid mist gas is further purified; finally, the residual trace acidic gas is absorbed and deodorized by a molecular sieve and an active carbon layer in the eleventh container, so that the concentrated acid mist is completely purified and the purified acidic gas meets the national emission standards.

Description

technical field [0001] The invention relates to a device for purifying concentrated acid mist. Background technique [0002] At present, the existing concentrated acid mist treatment devices include (washing towers, spray towers, and neutralization towers). At the moment, the water mist or alkaline liquid can absorb the concentrated acid mist, but because the contact area between the water mist or alkaline liquid and the concentrated acid mist is small and the time is short, the absorption and reaction time for the concentrated acid mist is very short. The purification efficiency is not high, and if the treatment is aimed at concentrated acid mist, the effect is not ideal, and it cannot meet the national emission standards. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a concentrated acid mist purification device with high purification efficiency. [0004] The present i...
