Activated carbon activation and regeneration device with self-adaptive function and activation and regeneration method thereof

Abstract

The invention discloses an activated carbon activation and regeneration device with a self-adaptive function and an activation and regeneration method thereof. Regenerated saturated activated carbon is transferred into activation equipment to be activated, so that energy is wasted. The device comprises a shell, sand grains, a first electrode plate, a second electrode plate, a temperature sensor, ahumidity sensor and a water spray nozzle. The inner cavity of the shell is filled with sand grains. A regeneration cavity for isolating sand grains is formed in the top of the inner cavity of the shell. The temperature sensor extends into the regeneration cavity. The humidity sensor is buried in sand in the inner cavity of the shell. A water nozzle is arranged at the bottom of the shell inner cavity, and the water nozzle is connected to an external water source. According to the invention, water in sand gaps is gasified into water vapor by utilizing heat generated during electric regeneration, and the water vapor penetrates through activated carbon during regeneration, so that the activated carbon is activated while being regenerated, and the operation of feeding the regenerated activatedcarbon into an activation furnace is omitted, in addition, the water vapor is generated by utilizing heat dissipated during electric regeneration, and extra energy consumption is not needed.

Description

technical field [0001] The invention belongs to the technical field of activated carbon regeneration, and in particular relates to a device and method for activating the activated carbon in the regeneration process, aimed at electrical regeneration of saturated activated carbon. Background technique [0002] During the adsorption process of activated carbon, the adsorbed substances will block the micropores of activated carbon, and the activated carbon will lose its purification ability. The saturated activated carbon can be regenerated to form secondary utilization. At present, domestic saturated activated carbon is ultimately regenerated by heat. Under the action of heat, saturated activated carbon can not only complete the desorption of adsorbed substances, but also carbonize itself, resulting in a significant decrease in the adsorption capacity of partially regenerated activated carbon. In response to this phenomenon, the saturated activated carbon regeneration process...

AI Technical Summary

Problems solved by technology

Transferring the regenerated saturated activated carbon to the activation equipment for activation will waste energy and cause a certain amount of waste during the transfer process

[0003] In addition, during the regeneration process of honeycomb activated carbon, there is likely to be a gap between the electrode plate and the carbon surface, which leads to the phenomenon of arc pulse discharge on the electrode plate.

Since the wall of the honeycomb activated carbon is thin, with a thickness of only 1.5mm, the arc pulse discharge phenomenon generated by the electrode plate will break down the wall of the honeycomb activated carbon and damage its structural integrity.
