In contrast to the general exhaust gas treatment solutions, acid mist exhaust gas is mostly treated by adsorption, absorption and filtration methods. Among them, adsorption and absorption methods are more commonly used.

• Absorption method

1, the main principle is to make full contact with gas and liquid, acid and alkali neutralization, so as to achieve the purpose of purification, to achieve the standard emissions.

2, this acid mist waste gas treatment method is simple to operate, less investment.

3, but energy and water consumption, high operating costs, the potential for secondary pollution. 　　

4, commonly used equipment: mainlyexhaust gas purification and scrubbing tower, acid mist spray tower, acid and alkali waste gas treatment equipment, pickling waste gas treatment equipment, acid mist waste gas treatment equipment, etc.

• Adsorption method

1, the main principle is to use the adsorption of adsorbent

2, the acid fog exhaust gas in the acid and other harmful components of the adsorption separation, to achieve the purpose of purification.

3, adsorption method is widely used in the current exhaust gas purification, simple operation

4、And it has good purification efficiency for removing the nitrogen oxides produced with nitric acid mist, and does not produce secondary pollution.

5、But due to the limited adsorption capacity of the adsorbent, resulting in large equipment, and the process is intermittent operation.

6、So the adsorption method is only applicable to purify and treat the exhaust gas with low concentration of acid mist. 　　

7、Commonly used equipment: the main activated carbon adsorber, exhaust gas adsorber, acid mist adsorber, etc.

8、The commonly used adsorbents are activated carbon, molecular sieve, silica gel, ammonia-containing coal sludge, etc. 　　

For the treatment of acid mist waste gas generated by different industries to have a targeted acid mist waste gas treatment program, blind selection may not only fail to achieve the purpose of purifying waste gas, but also may additionally increase the cost of enterprises.

Therefore, enterprises in the selection of exhaust gas treatment equipment according to their own actual situation, under the advice of environmental engineers to use a reasonable exhaust gas solution, to buy a formal and suitable exhaust gas purification equipment to better deal with exhaust gas.
