Abstract

The invention discloses an electrified heating regenerated active carbon adsorption purification system and an electrified heating regenerated active carbon adsorption purification method. The systemcomprises a filter, a cooler and at least more than two active carbon adsorbers, wherein an adsorption purification unit is arranged in the active carbon adsorber, and comprises an active carbon fiberbed layer, electrodes, a temperature sensor and an enclosure structure, the active carbon fiber bed layer is formed by overlapping active carbon fiber fabrics, a temperature sensor is arranged in thebed layer, the electrodes are arranged on any two opposite end surfaces of the bed layer, and the electrode adopts a mode that an electric-conducting band and an active carbon fiber fabric are overlapped layer by layer or the electric-conducting band and plural layers of active carbon fiber fabrics are overlapped. According to the invention, the electric-conducting bands are uniformly arranged inthe end surface area of the bed layer to ensure the uniform distribution of the bed layer current in the electric heating process, so that the uniform temperature rise of the active carbon bed layeris realized, organic matter desorption is thorough, regeneration is complete, and the electric heating filtering core can keep good adsorption performance for a long time.

Description

technical field [0001] The invention relates to the technical field of air pollution control, in particular to an activated carbon adsorption purification system and method for heating and regenerating through electricity. It can be used for industrial VOCs exhaust gas treatment, and can also be used for renewable chemical protection of toxic and harmful gases and purification of VOCs in indoor air. Background technique [0002] At present, the activated carbon adsorption treatment technology widely used in air pollution control projects uses activated carbon as an adsorbent to absorb pollutants in the air. After the activated carbon is saturated, an external heating medium (industrial water vapor, hot nitrogen or hot air) and activated carbon are introduced Perform heat exchange to heat up the activated carbon. During the heating process, the adsorbed pollutants are continuously desorbed from the activated carbon and converted into high-concentration pollutant vapors for co...
