Abstract

The invention discloses a low-concentration waste gas activated carbon adsorption and recovery device for production of a polyurethane chain extender, wherein the device comprises a device bottom plate, a drying fan base and recovery desorption tanks. The drying fan base is arranged in the middle of the left side of the device bottom plate; a drying fan is arranged on the drying fan base; a dryingpipe is arranged at a part, parallel to the device bottom plate, of the center of the drying fan, and the drying pipe is provided with two groups of branch pipes; the two groups of branch pipes are connected with two recovery desorption tanks through drying pipe matching holes formed in the two recovery desorption tanks. The two recovery desorption tanks are fixed on the device bottom plate, anda waste gas pipe is arranged in the middle of the drying fan base. The low-concentration waste gas activated carbon adsorption and recovery device for production of the polyurethane chain extender hasreasonable structure, has two recovery desorption tanks 4 for high-efficiency recovery operation, and is recommended to be widely used.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas recovery, and in particular relates to a low-concentration exhaust gas activated carbon adsorption recovery device for the production of polyurethane chain extenders. Background technique [0002] In the prior art, activated carbon fiber adsorption devices are often used to recover and treat organic waste gas. The activated carbon fiber adsorption device is composed of waste gas pretreatment system, adsorption / desorption system, drying and cooling system, recovery system, automatic control system and other parts. The organic waste gas is sent to the adsorber filled with activated carbon fiber after being pressurized by the fan. The organic molecules in the activated carbon fiber are adsorbed in the micropores of the activated carbon fiber. When the adsorber is saturated, the adsorber is heated and purged with water vapor, and the adsorber enters the desorption process to desorb the organic com...
