Embodiment Construction

[0024] Such as figure 1 In the shown desorption device for enhancing the desorption capacity of activated carbon, the internal space of the tank body is connected with but mutually insulated A zone and B zone, and activated carbon adsorption materials are placed in A zone and B zone respectively.

[0025] Area A and area B are respectively provided with parallel electrode plates A and electrode plates B, and the electrode plates A and electrode B are respectively connected to two poles of a high-frequency AC power supply.

[0026] At the same time of desorption, a high-frequency alternating current is applied to form a high-frequency alternating electric field between the A area and the B area of ​​​​the adsorption and desorption tank, so that the remaining adsorbed ions and exhaust gas molecules are oscillated and dropped from the activated carbon, and flow away with steam or inert airflow. .

Abstract

A desorption device for enhancing the desorption capacity of activated carbon disclosed by the present invention, in the inner space of the tank body of the adsorption and desorption tank, there are A zone and B zone which are connected but mutually insulated, and activated carbon adsorption materials are respectively placed in A zone and B zone; A zone and Area B is provided with parallel electrode plate A and electrode plate B respectively, which are respectively connected to the two poles of high-frequency AC power supply; the desorption gas is passed through at the same time as high-frequency alternating current, forming a high-frequency alternating electric field between area A and area B, The adsorbed ions and exhaust gas molecules are shaken off the activated carbon and flow away with steam or inert airflow. The invention realizes the desorption of the adsorption material safely, conveniently and quickly, and the desorbed solvent can be fractionated and separated for recycling.

Description

technical field [0001] The invention relates to a desorption technology of an adsorption material. Background technique [0002] The so-called regeneration of activated carbon actually refers to the operation and method of changing the external environment of activated carbon through external stimuli to reactivate the active components to achieve the purpose of repeated use. [0003] Activated carbon regeneration method, activated carbon regeneration is to reactivate the fully adsorbed activated carbon after being treated under certain conditions. Activated carbon has been widely used in environmental protection, industry and civil use, and has achieved considerable results. However, after the adsorption saturation of activated carbon is replaced, the use of activated carbon adsorption is a physical process, so high-temperature steam can also be used. The impurities inside are desorbed and restored to their original activity, so as to achieve the purpose of repeated use, wh...
