Laboratory Waste Gas TreatmentThere are many methods, and the exhaust gas treatment method can be selected according to the characteristics of the exhaust gas and the requirements of the emission standard. The following are common treatment methods for laboratory exhaust gas:
1. Condensation method
The water vapor and organic substances in the exhaust gas are condensed into a liquid state by means of cooling, and condensing equipment is usually used to purify the exhaust gas and treat the exhaust gas.
2. Adsorption method
Harmful substances in the exhaust gas can be adsorbed out by using materials that can be adsorbed, such as activated carbon, etc., which are usually used to treat high-concentration organic waste gases.
3. Chemical method
The exhaust gas is passed through the chemical solution that can absorb the substance, and the harmful substances in the exhaust gas are converted into non-toxic and harmless substances by chemical reaction, and the common chemical absorption substances are sodium hydroxide, calcium hydroxide, etc., which can usually treat the exhaust gas containing hydrogen sulfide.
4. Biological law
The exhaust gas is converted by the metabolism of microorganisms, and is usually used to treat ammonia and other substances.
Fifth, the combustion method
Exhaust gases can usually be treated by combustion, and incinerators, burners, and other equipment can usually be used to treat high-concentration organic waste gases and toxic gases.
There are many ways to treat waste gas, and in general, it is necessary to choose according to a series of factors such as the nature, type, and concentration of the gas, so as to treat the waste gas as safely and effectively as possible under the premise of ensuring safety.
