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

Abstract

The invention discloses an activated carbon activation and regeneration device with adaptive function and an activation and regeneration method thereof. It is a waste of energy to transfer the regenerated saturated activated carbon to the activation equipment for activation. The invention includes a casing, sand grains, a first electrode plate, a second electrode plate, a temperature sensor, a humidity sensor, and a water spray nozzle. The inner cavity of the shell is filled with sand grains. The top of the inner cavity of the shell is provided with a regeneration cavity that isolates the sand particles from the outside. A temperature sensor protrudes into the regeneration chamber. The humidity sensor is embedded in the sand grains in the inner cavity of the housing. The bottom of the inner cavity of the shell is provided with a water spray nozzle; the water spray nozzle is connected to an external water source. The invention utilizes the heat generated during electrical regeneration to vaporize the water in the gaps of the sand grains into water vapor, and makes the water vapor pass through the activated carbon being regenerated, so that the activated carbon is activated at the same time of regeneration, eliminating the need for the activated carbon to be sent after regeneration operation into the activation furnace; in addition, water vapor is generated using the heat dissipated during electrical regeneration without additional energy consumption.

Description

technical field [0001] The invention belongs to the technical field of activated carbon regeneration, and in particular relates to an electric regeneration of saturated activated carbon, and a device and method for activating the activated carbon in the regeneration process. 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. Saturated activated carbon can be regenerated for secondary use. At present, the saturated activated carbon in China is, in the final analysis, 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 ha...

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.
