Problems solved by technology

[0005] The activated carbon heating method currently used in the market generally uses one-way electric heating. The disadvantage is that the output power of single-phase electricity is limited, resulting in limited regeneration capacity of activated carbon.
The heating method often uses electric heating through resistance wires. The disadvantage is that the heating of the activated carbon bed by resistance heating is uneven, the temperature in the area close to the resistance wire is high, and the temperature in the area far away from the resistance wire is low, the energy utilization rate is low, and the energy consumption is large.

Abstract

The invention discloses an electrode for activated carbon electro-thermal regeneration equipment. The electrode comprises a cylindrical electrode assembly and insulating plates, wherein the cylindrical electrode assembly comprises electricity input electrodes and electricity output electrodes which are arranged at intervals in a sleeved mode, the insulating plates are arranged in the cylindrical electrode assembly alternately and divide each electricity input electrode into a first electricity input section, a second electricity input section and a third electricity input section which are not communicated, and correspondingly, the insulating plates divide a carbon bed between the electricity input electrodes and the electricity output electrodes into a first area, a second are and a third area; the first electricity input section, the second electricity input section and the third electricity input section of each electricity input electrode are used for being connected with a first phase line, a second phase line and a third phase line of a three-phase supply respectively, and the electrode output electrodes are used for being connected with a middle line of the three-phase supply. The electrode for the activated carbon electro-thermal regeneration equipment is a three-phase equilibrium electrode for activated carbon electro-thermal regeneration, and has the advantage that the defect that the output power of a single-phase supply is limited is overcome by being used in cooperation with the three-phase supply, so that the production capacity of the activated carbon regeneration equipment is improved.

Description

technical field [0001] The invention relates to the field of activated carbon regeneration, in particular to an electrode used for activated carbon electrothermal regeneration equipment and a use method. Background technique [0002] Activated carbon is a carbonaceous material with developed pore structure, large specific surface area and strong adsorption capacity. It is widely used in the water treatment industry. Activated carbon will inevitably reach adsorption saturation after a period of time, and the adsorption efficiency will decrease. If it is directly discarded and replaced with new carbon, it will not only pollute the environment but also generate a lot of waste of resources and increase operating costs. Therefore, after the activated carbon is saturated, it can be regenerated in order to save resources and reduce operating costs. Activated carbon regeneration is to treat the activated carbon saturated with various impurities through physical, chemical or biochem...
