Description

Technical Field

[0002] In many industrial production processes, the waste gas generated often contains acidic or alkaline gases, such as hydrogen sulfide and ammonia. These acid-base waste gases are harmful to the environment and human health. If these acid-base waste gases are discharged directly, they will produce acid mist with strong corrosiveness and toxicity. These acid mists will not only cause huge pollution to the workplace, but also cause acid deposition in the atmospheric environment. Therefore, the waste gas needs to be treated before it is discharged to reduce the harm to the environment.

[0003] At present, the treatment method of waste gas treatment equipment is generally to pass the waste gas into a neutralization reaction liquid, and produce a chemical reaction through the full contact between the waste gas and the neutralization reaction liquid, thereby neutralizing the acidity and alkalinity of the waste gas. The reaction liquid will gradually become saturated during the treatment process, and the adsorption capacity will decrease. Therefore, it is necessary to manually replace the reaction liquid regularly. When replacing the reaction liquid, the saturated reaction liquid needs to be completely removed and then new reaction liquid is injected. The replacement efficiency is low. At the same time, affected by the saturation of the reaction liquid, after the neutralization reaction of the waste gas, some of the waste gas may not react fully, thereby affecting the cleanliness of the exhaust gas. For this reason, an acid-base waste gas treatment device for waste gas treatment is proposed to solve the above-mentioned problems. Utility Model Content
