Device capable of cyclically treating acidic gas

Abstract

The invention creatively provides a device capable of cyclically treating acidic gas. The device comprises a gas collecting cover, a collecting box, a neutralizing box, a filtering box, a gas conveying pipe and connecting pipes, wherein the gas collecting cover and the collecting box are connected through the gas conveying pipe; the neutralizing box is positioned between the collecting box and thefiltering box; the collecting box and the neutralizing box are connected through a connecting pipe; the neutralizing box and the filtering box are connected through a connecting pipe; a plurality ofneutralizing interlayers are uniformly arranged in the neutralizing box; a circulation pipe is arranged at the outer side of the neutralizing box; the two ends of the neutralizing box are communicatedthrough the circulation pipe. The device capable of cyclically treating acidic gas creatively provided by the invention has the advantages that the two ends of the neutralizing box are communicated through the circulation pipe; an air pump is arranged on the circulation pipe; the multiple circular flowing of the acidic gas in the neutralizing box can be realized, so that the acidic gas treatmentefficiency is improved; when the cyclic neutralizing reaction is performed in the neutralizing box, the two ends of the neutralizing box need to be ensured to be sealed; the collecting box can collectand store the acidic gas; the acidic gas is supplied and compressed at the proper time.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a device capable of recycling acid gas. Background technique [0002] The acid gas treatment equipment commonly used in the iron and steel industry is only for a single treatment of acid gas, that is, the collected acid gas is directly passed into alkaline water or other alkaline reagents for a single neutralization reaction, and then it is directly discharged through filtration. This treatment method is prone to the phenomenon of incomplete neutralization reaction, and the above steps are repeated if the treated gas does not meet the standard. The treatment period is longer and the efficiency is lower. Contents of the invention [0003] In view of this, the present invention aims to propose a device that can recycle acid gas, so as to realize the recycle treatment of acid gas in the neutralization tank and ensure more complete neutralization reacti...
