Abstract

The invention discloses an activated carbon low-pressure arc striking regeneration device and a regeneration method. The side facing the first regeneration cabin and the second regeneration cabin of the present invention is open, and the open sides of the first regeneration cabin and the second regeneration cabin are all fixed with metal screens; the first regeneration cabin and the second regeneration cabin Electrode plates are fixed on the other side opposite to their respective metal screens; temperature sensors are installed in the first regeneration cabin and the second regeneration cabin; the first regeneration cabin and the second regeneration cabin are connected with the first mechanical vibrator and the second regeneration cabin respectively. The second mechanical vibrator is connected; the first mechanical vibrator and the second mechanical vibrator are respectively fixed on the first base and the second base; the first base is driven by a horizontal driving member; the top surfaces of the first base and the second base, etc. high. The invention utilizes activated carbon to conduct heat and arc to generate heat to activate and regenerate the activated carbon at high temperature; at the same time, the arc forms an electric hammer effect under low voltage, which has a pore-enlargement effect on the micropores inside the activated carbon, and further improves the regeneration effect of the activated carbon.

Description

technical field [0001] The invention belongs to the field of activated carbon regeneration, and in particular relates to an activated carbon low-voltage arc ignition regeneration device and method. Background technique [0002] Activated carbon has a good adsorption effect and is widely used to purify various pollutants. During the adsorption process of activated carbon, the adsorbed substances will adhere to the surface of activated carbon and block in the pores of activated carbon, which greatly weakens or even loses the adsorption capacity of activated carbon. The used activated carbon with weakened adsorption capacity is called saturated activated carbon. The saturated activated carbon can be activated and regenerated, that is, by decomposing and desorbing the adsorbed substances to restore the adsorption capacity, realizing the recycling of activated carbon and greatly saving resources. [0003] At present, there are many regeneration methods for activated carbon, such...

Problems solved by technology

But it also has obvious disadvantages: due to the need to ensure a certain regeneration time and air tightness, the regeneration equipment is huge, and there are many auxiliary equipment, the equipment investment is large, and the regeneration time is long, the energy consumption is high, and the heat dissipation loss is also large. , the loss of carbon is also large

Because saturated activated carbon adsorbs a large amount of various pollutants and impurities, adheres to its surface and blocks in its pores, so that its resistance increases by tens of hundreds of times, and even some activated carbon particles cannot contact each other and are insulated.

Therefore, it is not easy for this kind of saturated activated carbon to be energized at low voltage and generate enough heat for activation, and if it is directly energized at high voltage, it will easily lead to the breakdown of activated carbon, destroy the structure of activated carbon or even burn it directly.

Therefore, some pretreatment methods and technologies for the regeneration of saturated activated carbon have been proposed or used, but increasing the pretreatment stage will increase the corresponding equipment and energy consumption, which is different from the saturated activated carbon regeneration technology to reduce equipment weight, lower energy consumption, and speed. Faster development goes in the opposite direction
