Activated carbon low-voltage arc ignition regeneration device and regeneration method

Abstract

The invention discloses an activated carbon low-voltage arc ignition regeneration device and a regeneration method. The opposite sides of a first regeneration cabin and a second regeneration cabin are open, and metal screens are fixed to the open sides of the first regeneration cabin and the second regeneration cabin; electrode plates are fixed on the other sides, opposite to the respective metal screens, in the first regeneration cabin and the second regeneration cabin; temperature sensors are arranged in the first regeneration cabin and the second regeneration cabin; the first regeneration cabin and the second regeneration cabin are connected with a first mechanical vibrator and a second mechanical vibrator respectively; the first mechanical vibrator and the second mechanical vibrator are fixed on a first base and a second base respectively; the first base is driven by a horizontal driving piece; and the top faces of the first base and the second base are equal in height. Activated carbon is activated and regenerated at high temperature by utilizing conductive heat production and arc striking heat production of the activated carbon; and meanwhile, an electric hammer effect is formed by the electric arc under low voltage, micropores in the activated carbon are expanded, and the regeneration effect of the activated carbon is further improved.

Description

technical field [0001] The invention belongs to the field of activated carbon regeneration, and in particular relates to an activated carbon low-pressure arc ignition regeneration device and method. Background technique [0002] Activated carbon has a good adsorption effect and is widely used to purify and treat 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, the adsorption capacity can be restored by decomposing and desorbing the adsorbed substances, so as to realize the recycling of activated carbon and greatly save resources. [0003] At present, there are many regeneration methods for a...

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
