Abstract

The invention discloses an activated carbon electric heating regeneration device capable of maintaining stable resistance and a regeneration method of the activated carbon electric heating regeneration device. The device comprises a regeneration bin, a first movable electrode plate and a second movable electrode plate. A plurality of receding holes are formed in the two sides of the regeneration bin. The first movable electrode plate and the second movable electrode plate are respectively positioned on two sides outside the regeneration bin and are in sliding connection with the regeneration bin. And a plurality of electrode convex columns are arranged on the inner side surfaces of the first movable electrode plate and the second movable electrode plate. And each electrode convex column respectively penetrates through each abdicating hole in the corresponding side of the regeneration bin. And the first movable electrode plate and the second movable electrode plate can slide towards each other or away from each other under the driving of the driving device. By adjusting the depth of the electrode convex columns penetrating into the granular activated carbon group, the influence of the resistivity of the granular activated carbon on the regeneration power along with the temperature change is counteracted, the conditions of local short circuit and insufficient regeneration temperature are avoided, and the electric heating regeneration power is kept at the optimal rated power.

Description

technical field [0001] The invention belongs to the field of activated carbon regeneration, and in particular relates to an activated carbon electrothermal regeneration device for maintaining stable electrical resistance and a regeneration method thereof. Background technique [0002] Activated carbon regeneration is to desorb the adsorbed substances from waste carbon to restore the original adsorption performance. The principle of activated carbon electrical regeneration is to energize the activated carbon filled between the electrode plates, and the carbon particles will generate Joules under the action of the current. heat to achieve thermal desorption and desorption of organic substances by increasing the temperature, thereby realizing regeneration. [0003] Activated carbon has semiconducting properties, and as the temperature increases, the resistance of the carbon particles decreases and finally tends to be stable. During the regeneration process, if the resistance o...

Problems solved by technology

During the regeneration process, if the resistance of activated carbon is too small, it will cause a local short circuit, and if the resistance is too large, the internal temperature of the regeneration furnace will not rise.

In the current activated carbon regeneration technology, it is still not perfect to change the resistance of the carbon particle population during the regeneration process to maintain it at an appropriate level.
