Abstract

The invention relates to a hazardous waste activated carbon green regeneration upgrading system, which comprises a desorption carbon tank, a high-temperature plasma device, a variable-frequency heater, a catalytic oxidation box, a carbon activation furnace and a gas-gas heat exchanger, an inlet of the desorption carbon tank is communicated with a nitrogen pipeline, and an outlet of the desorption carbon tank is connected with the high-temperature plasma device, the carbon activation furnace and the catalytic oxidation box, the outlet end of the high-temperature plasma device is sequentially connected with a first gas-gas heat exchanger and a second gas-gas heat exchanger. The hazardous waste activated carbon green regeneration upgrading system and method can be widely applied to sewage treatment plants, coking wastewater plants, chemical plants, pharmaceutical factories, pesticide factories and fine chemical factories, effectively fill the blank in the field in China, are green and environmentally friendly, and are suitable for popularization and application in the field of environmental protection.

Description

technical field [0001] The invention belongs to the field of environmental engineering and relates to industrial hazardous waste treatment technology, in particular to a green regeneration and quality improvement system and method for hazardous waste activated carbon. Background technique [0002] Activated carbon is a good adsorption material, which is widely used in all walks of life. It has a good adsorption effect on organic matter in sewage and VOCs in waste gas. It is often used to purify sewage and waste gas and protect the environment. However, the quality of used activated carbon will decline. If it cannot be regenerated, it will become hazardous waste and cause secondary pollution. According to statistics, the annual waste activated carbon produced in my country is as high as 30 million tons, accounting for more than 50% of solid hazardous waste. [0003] At present, most of the activated carbon regeneration processes in my country use rotary kiln technology. The g...
