Activated carbon adsorption and desorption regeneration device for organic waste gas treatment

Abstract

The invention discloses an activated carbon adsorption and desorption regeneration device for organic waste gas treatment. The activated carbon adsorption and desorption regeneration device comprisesa waste gas treatment box. An infrared heating device works, so that the temperature of activated carbon in the waste gas treatment box is increased, adsorbed components on the activated carbon are desorbed and volatilized, and the desorbed and volatilized components are fed into a catalytic combustion device to be combusted and decomposed into hot air such as CO2 and H2O steam by starting a desorption fan; one part of the hot air returns to an activated carbon adsorption box to continue to heat the activated carbon, the other part of the hot air is emptied through the desorption fan, the activated carbon can be regenerated by circulating in the hot air multiple times, and the utilization rate of the activated carbon is increased; the path of a gas passing through a combustion chamber is increased through a partition plate, and the flow speed of the gas in the combustion chamber can be reduced, so that the time of the gas in the combustion chamber is prolonged, and the gas is combustedmore sufficiently and thoroughly.

Description

technical field [0001] The invention relates to the field of organic waste gas treatment, in particular to an activated carbon adsorption and desorption regeneration device for organic waste gas treatment. Background technique [0002] Organic waste gas mainly includes hydrocarbon compounds, benzene and benzene series, alcohols, ketones, phenols, aldehydes, esters, amines, nitriles, cyanides and other organic compounds. Organic waste gas activated carbon adsorption tower is widely used in furniture wood industry, chemical coating, metal surface treatment and other places where organic waste gas and peculiar smell are generated by spraying, painting, drying, etc., using high-quality adsorption activated carbon as the adsorption medium, and organic waste gas passes through multi-layer adsorption layers Filter and adsorb to achieve the purpose of purifying exhaust gas. [0003] When the adsorption concentration of activated carbon reaches a certain value, it will no longer be ...

AI Technical Summary

Problems solved by technology

[0003] When the adsorption concentration of activated carbon reaches a certain value, it will no longer be adsorbed. At this time, activated carbon will lose the function of filtering organic waste gas. At this time, it is necessary to start a catalytic combustion device to realize the desorption and regeneration function of activated carbon. The current activated carbon desorption The regeneration device cannot stir the activated carbon, so the heating of the activated carbon is uneven and incomplete, and the desorption effect of the activated carbon inside the adsorption bed is not good, which affects the desorption quality of the activated carbon and is not conducive to the regeneration of the activated carbon
