Closed-loop type organic waste gas adsorption and desorption device with high adsorption capacity and utilization rate

The invention relates to the technical field of organic waste gas treatment, and discloses a closed-loop type high-adsorption-capacity-utilization-rate organic waste gas adsorption and desorption device which comprises an outer wrapping layer arranged on the outermost layer, four switching areas located at the four corners of the inner side of the outer wrapping layer and four-stage honeycomb activated carbon modules located between every two adjacent switching areas. The four switching areas are distributed anticlockwise from the lower left corner and are respectively a first switching area, a second switching area, a third switching area and a fourth switching area. The device is composed of four switching areas and four stages of honeycomb activated carbon modules, and the switching area is configured between every two stages of honeycomb activated carbon modules, so that a closed-loop operation mode is formed, and the adsorption capacity which is not fully exerted in activated carbon cascading can be furt
