Problems solved by technology

[0002] The organic waste gas generated in industrial production cannot be discharged directly into the atmosphere because it contains a large amount of toxic organic matter. There are many technologies in the prior art to treat such organic waste gas, one of which is activated carbon adsorption. That is, the organic waste gas is adsorbed in the adsorption tower; another method is to catalyze the oxidation of the organic gas at a high temperature, so that the organic matter is burned and then discharged; both m

Abstract

The invention discloses an organic gas adsorption, desorption and purification device in the field of waste gas purification equipment and comprises a filtering device, an outlet of which is connected with an adsorption device, and an outlet of the adsorption device is communicated with air through an air exhauster, the adsorption device comprises two adsorption towers which are serially connected and arranged; an inlet valve and an outlet valve are respectively arranged at an inlet and an outlet of the adsorption towers, active carbon adsorptive filtering material is arranged inside the adsorption towers, and a circulating wind outlet is arranged behind the inlet valve, a circulating wind inlet is arranged in front of the outlet valve, disconnecting valves are arranged on corresponding pipelines of the circulating wind inlet and outlet; furthermore, a fire arrestor, a waste gas burner and a circulating fan are connected between the circulating wind outlet and the circulating wind inlet through circulating wind pipes; one part of the exhausted gas of the waste gas burner is exhausted into the circulating wind inlet through the circulating fan and the other part of the exhausted gas is directly exhausted into air, and a cooling fan is arranged at one side of the circulating wind inlet. The invention can implement adsorption, desorption and purification at the same time, thus improving working efficiency, being applicable for industrial production which needs to process organic waste gas.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to an organic waste gas treatment device. Background technique [0002] The organic waste gas generated in industrial production cannot be discharged directly into the atmosphere because it contains a large amount of toxic organic matter. There are many technologies in the prior art to treat such organic waste gas, one of which is activated carbon adsorption. That is, the organic waste gas is adsorbed in the adsorption tower; another method is to catalyze the oxidation of the organic gas at a high temperature, so that the organic matter is burned and then discharged; both methods have their shortcomings; the catalytic oxidation method is due to the concentration of the organic gas It is not enough to make it burn independently, and it needs to consume a large amount of gas or oil for auxiliary combustion, which has high energy consumption and is not economical; using the adsorpt...
