The exhaust gas is at a high temperature, which requires a large amount of water for cooling through spraying; in addition, activated carbon adsorption is also used. What should be done? !
Thread Content
The exhaust gas temperature is around 160°C, and it needs to be cooled to room temperature. The flow rate is about 6,000 cubic meters per hour; the main component of this gas is air, and a large amount of water is required for cooling. Moreover, there is activated carbon adsorption behind it; as a result, the water vapor generated by cooling and evaporation is drawn into the adsorption tower, which has a significant impact! Do any of you have any good suggestions? ! Thank you! ! reward_7ree
Adding an air cooler, or a heat recovery heat exchanger, will work either way
From an energy-saving perspective, waste heat should be recovered first.
Can 160 degrees be used for waste heat utilization? !

Using water is definitely not good; it has a too great impact on the molecular sieve. Consider waste heat recovery or air cooling instead!
If heat cannot be recovered, install an exchanger and use a cooling tower for heat dissipation.
The waste heat from exhaust gases is first recovered through heat exchange with the exhaust gases before being utilized. And then process it.
Could you provide the background of the case? Are there any other devices on the production line?
This is the problem you have with fermentation off-gases. Fermentation off-gas is very hot and comes in large quantities; conventionally, it is cooled by recovering heat.
