Adsorption desorption condensation recovery method for exhausting activated carbon and device thereof

Abstract

The invention discloses an adsorption desorption condensation recovery method for exhausting activated carbon and a device thereof. The method comprises: introducing production exhaust gas into activated carbon adsorption devices of several independent adsorption zones through a blower fan, and discharging the exhaust gas to the environment after being absorbed by the activated carbon, transferring the adsorbed saturated activated carbon from the activated carbon adsorption device to an activated carbon desorption device, performing desorption on exhaust gas from the activated carbon through aheat medium, reinstalling the desorbed activated carbon to the activated carbon adsorption device, and introducing the exhaust gas to a condenser for cooling and recycling. The method has the advantages of high efficiency, environmental protection, low operating cost; the device comprises a first blower fan, an activated carbon adsorption device connected to the first blower fan through a three-way pipe, the mobile activated carbon desorption device and a condenser, an air inlet of the condenser is connected to an air outlet of the activated carbon desorption device through a pipeline, and anexhaust port is connected to the three-way pipe which is connected between the blower fan and the activated carbon adsorption device. The device has a simple structure and stable operation, and is adapted to the requirement of different enterprises.

Description

technical field [0001] The invention relates to the field of waste gas recovery treatment and devices, in particular to a method and device for waste gas activated carbon absorption and desorption condensation recovery. Background technique [0002] At present, exhaust gas pollution is becoming more and more prominent, and controlling the emission of exhaust gas is one of the important tasks of environmental governance. Activated carbon has a good adsorption effect on volatile organic waste gas, but there is a certain replacement cycle for activated carbon adsorption. After the adsorption is saturated, the volatile organic waste gas in the waste gas cannot be removed and needs to be replaced. Therefore, the regeneration of activated carbon has important economic and social significance ; The current activated carbon adsorption device generally needs to stop production when replacing the activated carbon, which causes larger economic losses to the production enterprise.
