It is an excellent adsorbent and catalytic carrier, which is widely used in various fields of environmental protection, food industry, pharmaceutical industry, agriculture, catalysts and their carriers, national defense, aerospace and people's daily life. In recent years, with the development of industry, activated carbon has played a pivotal role in the field of environmental protection and has become an adsorption material on which human beings depend for survival.

However, activated carbon is expensive, and each replacement of new activated carbon will inevitably increase the company's operating costs. Therefore, it is necessary to study the regeneration of saturated activated carbon. Through the regeneration of activated carbon, impurities in the used activated carbon can be desorbed to restore its original activity, achieving the purpose of reuse and circular economy.

[0004] In order to further improve the utilization rate of energy, save energy and reduce emissions, it is urgent to develop a connected furnace so that the activated carbon regeneration furnace does not require an external heat source. Utility Model Content

[0024] Specific embodiments of the utility model:

[0025] The furnace body is divided into a combustion chamber 2, an incinerator 5, an ash collection chamber 6 and a regeneration furnace 9. The hazardous waste incinerator and the activated carbon regeneration furnace are combined into one. The temperature of the hazardous waste combustion chamber can reach about 1300°C. After the incineration of the hazardous waste, the temperature is reduced and the temperature in the regeneration furnace can reach 900°C, which is used in the regeneration of the activated carbon to restore its adsorption performance.

[0026] Specifically, fuel enters from the burner 4 on the side of the combustion chamber 2 to provide heat for the entire integrated furnace. Solid waste enters from the solid waste inlet 1 above the combustion chamber 2, and liquid waste is sprayed from the side of the combustion chamber 2 by the spray gun 3 to allow the waste to fully react.

After the hazardous waste is burned, the temperature at the regeneration furnace 9 drops to about 900°C. At this temperature, the activated carbon can fully desorb the impurities in its gaps and restore its adsorption capacity. At the same time, the regeneration furnace 9 is an uninterrupted rotating furnace, which can make the activated carbon fully mixed and reacted to restore its original activity.
