Airflow drying waste gas circulation problem
Thread Content
The factory now has a set of flash drying equipment. Because the exhaust gas has a strong smell, it is considered to be a closed circulation system. Does anyone have experience in how to dehumidify and circulate the exhaust gas?
It can cool down and dehumidify. Considering the resistance, a fan needs to be added. Chilled water is used for cooling and dehumidification, and a chiller is required. Equipment investment and operating costs are relatively high.
The possibility of achieving a cycle is not very high. --Because the exhaust gas after drying contains solvents that need to be evaporated and has a certain degree of saturation, recycling must first reduce the content of the solvent in the exhaust gas. The theory can be realized without making economic sense. It is suggested that only considering "smell" removal may be the most feasible. The plan is as follows: The exhaust gas enters the scrubber. If insufficient pressure is eliminated, fan pressure can be considered. Thinking about how to deal with the washing liquid (or water)!
