Abstract

The invention provides an acidic waste gas treatment device and belongs to the technical field of gas treatment equipment. The acidic waste gas treatment device comprises a liquid storage tank, a first gas-liquid mixer and a conveying pump, wherein the first gas-liquid mixer is provided with a first mixing chamber, a first liquid inlet, a first liquid outlet and a first gas inlet for inputting the acidic waste gas; the first gas inlet, the first liquid inlet and the first liquid outlet are all communicated with the first mixing chamber; a first input hole and a first output hole are formed on the liquid storage tank; an input end of the conveying pump is connected with the first output hole; an output end of the conveying pump is connected with the first liquid inlet; the first liquid outlet is connected with the first input hole. The acidic waste gas treatment device is simple in structure, small in volume, low in use cost and capable of reducing the discharge index and processing cost of the acidic waste gas.

Description

technical field [0001] The invention relates to the technical field of gas treatment equipment, in particular to an acid waste gas treatment device. Background technique [0002] In chemical reaction experiments, various gases are usually produced, such as chlorine, nitrogen oxides, sulfur dioxide, hydrogen sulfide and other acidic waste gases. How to deal with these waste gases, especially acidic waste gases, has become a difficult problem in laboratory waste gas treatment. At present, the treatment methods of acid waste gas mainly include: 1) Dissolution method: pass the waste gas into a solvent, and use the solvent to completely or mostly dissolve the waste gas. 2) Combustion method: Some harmful combustible gases are ignited and burned in the discharge hole to eliminate pollution. For example, carbon monoxide, etc. 3) Neutralization method: For gas with strong acidity or alkalinity, use appropriate alkali or acid to absorb. 4) Adsorption method: select an appropriate ...
