How to treat exhaust gas
Thread Content
Synthetic waste gases are generally absorbed directly in water, or neutralized with alkalis, incinerated, or adsorbed, among other methods； How is waste gas from fermentation handled? ? Some people say that sodium hypochlorite, along with alkali and water, can be used for absorption, but the temperature of the waste gases during disinfection is around 100°C.
Gas composition, flow rate? What are the processing requirements?
How large is it? What are the main components?
The maximum flow rate is 100 m3/min; the gases involved are mainly air, carbon dioxide, and odors from various bean and rice flours. Fermentation air is provided for the bacteria’s respiration; the steam released during pasteurization is at a high temperature
The maximum flow rate is 100 m3/min; the gases involved are mainly air, carbon dioxide, and odors from various bean and rice flours. Fermentation air is provided for the bacteria’s respiration; the steam emitted during pasteurization is at a high temperature. The requirement for processing is that it should have no taste
6000 m3/h; although the temperature is a bit high, it’s not that difficult. It mainly depends on how much you’re willing to invest.
Small companies save wherever they can :lol

Two-stage spraying + activated carbon adsorption, then discharge. Activated carbon is a safe option; if the odor isn’t strong, it’s not necessary to use it.
There are no harmful gases either, and the smell should not be strong; adding a two-stage water spray will do
Mainly during disinfection, the smell of high-temperature exhaust gas is quite strong, but it is not harmful. The disinfection time is about half an hour, and the temperature of the waste gas is around 100°C. If cooled with water, the water temperature rises quickly; the mist discharged is unsightly, and the amount of water that evaporates is likely to be high as well
