Engineering background: During production in this workshop, high-temperature exhaust gas is generated, with a peak emission of 15000 cubic meters per hour. The exhaust gas temperature is high and contains odors. It has a significant impact on the indoor environment and the health of workers.

After field investigation, the engineer designed an exhaust plan consisting of activated carbon and centrifugal fan. The exhaust system first captures the exhaust gas through a semi closed gas collection hood, and then directs the gas to the activated carbon adsorption box. Activated carbon is responsible for adsorbing organic components such as ethanol and some odors. After the gas meets the standard, it is discharged from a 5-meter-high chimney
