Abstract

This utility model discloses a methanol volatile gas recovery device, comprising: a recovery tank, a vacuum pump installed on one side of the recovery tank, an alcohol gas suction pipe fixedly installed on the vacuum pump, an alcohol gas delivery pipe fixedly installed on the vacuum pump, one end of the alcohol gas delivery pipe installed in the inner cavity of the recovery tank, an exhaust stack installed at the end of the alcohol gas delivery pipe, and multiple exhaust holes opened on the exhaust stack; a circulating water pump is installed on the other side of the recovery tank. In use, this utility model uses the vacuum pump, alcohol gas suction pipe, and alcohol gas delivery pipe to transport methanol volatile gas to the exhaust stack, and then discharges it into the aqueous solution through the multiple exhaust holes. As the methanol volatile gas forms bubbles in the aqueous solution and rises, it dissolves. The circulating water pump then transports the aqueous solution to a spray station, where it is sprayed by multiple nozzles. This further dissolves any undissolved methanol volatile gas as it rises, resulting in more complete dissolution of the methanol volatile gas and improved recovery efficiency.
