Problems solved by technology

However, activated carbon has the risk of over-temperature combustion (the desorption temperature must be less than or equal to 120°C), and organic matter with a high boiling point cannot be completely desorbed; traditional activated carbon adsorption devices, the adsorption efficiency gradually decays over time

Abstract

The invention discloses a small-air-volume zeolite adsorption bed organic waste gas treatment system, and belongs to the technical field of organic waste gas treatment. The system comprises a filtering device, an adsorption device comprising a plurality of zeolite adsorption beds, and an adsorption fan which are connected in sequence, wherein the adsorption device is connected with the catalytic combustion device; a desorption gas inlet and a desorption gas outlet which are used for circulating desorption gas flow are formed in the zeolite adsorption bed; the catalytic combustion device is provided with a treatment inlet and a tail gas outlet; the tail gas outlet is connected with the desorption gas inlet through a tail gas pipeline, and the adsorption device is subjected to desorption treatment by utilizing high-temperature tail gas; and a desorption fan is arranged on the tail gas pipeline, and the treatment inlet is connected with the desorption gas outlet through a treatment pipeline. The device is suitable for effectively treating organic waste gas under the working conditions of small air volume, low concentration and discontinuous production; wherein the treatment efficiency of catalytic combustion is improved, energy consumption is reduced, and the overall manufacturing cost of system equipment is low.

Description

technical field [0001] The invention belongs to the technical field of organic waste gas treatment, and in particular relates to a small air volume zeolite adsorption bed organic waste gas treatment system. Background technique [0002] At present, mainstream organic waste gas treatment equipment is mostly suitable for large air volume and continuous production conditions, such as zeolite runner concentration device, activated carbon adsorption device, regenerative incinerator (RTO), direct-fired incinerator, etc. For small air volume, medium and low concentration and discontinuous production conditions (such as car 4S shop painting, spot repair painting, outdoor mobile spraying operations, passenger car and ship painting), there is serious energy waste, safety risks, and inconvenience when using the above equipment transport problem. [0003] The regenerative incinerator (RTO) needs to maintain the furnace temperature at 750-850°C, so it is suitable for use in continuous p...
