Organic adsorption saturated active carbon regeneration device

Abstract

An organic adsorption saturated active carbon regeneration device comprises a high temperature thermal decomposition furnace (1) and a gasification cracking furnace (12). A spiral guiding sheet (31) is arranged on the internal wall of the furnace body of the gasification cracking furnace (12). A sealed jacket (10) for air flowing is covered on the outer shell of the gasification cracking furnace (12), and the part covering the furnace head (20) and the part covering the furnace tail (8) are communicated with each other. Industrial waste organic substances and waste grease are burned in the high temperature thermal decomposition furnace (1), and the generated high-temperature flue gas is introduced into the sealed jacket (10) through a waste heat pipe (7). The furnace tail (8) of the gasification cracking furnace (12) is connected to a high efficient gas / solid separating tower (5), and the overall body is sealed. The organic adsorption saturated active carbon regeneration device also comprises a re-burning chamber (16), an exhaust heat boiler (28), and a waste gas processing system (29). The provided device can reduce the energy loss, is capable of achieving continuous production, regenerates the resources, and does not generate secondary pollution.

Description

technical field [0001] The invention relates to the technical field of activated carbon regeneration, in particular to a device for performing high-temperature continuous regeneration and activation of organic matter adsorption saturated activated carbon by using waste heat. Background technique [0002] Activated carbon has a highly developed pore structure and a large specific surface area, and is widely used in various industries. It can effectively adsorb harmful substances in water, such as organic matter and heavy metal ions, to purify wastewater. However, the high price of activated carbon makes it difficult to put activated carbon into practical application. In addition, activated carbon is also a product that consumes a lot of resources and energy. If the saturated activated carbon is not recycled, it will be a great waste of resources and will cause secondary pollution. [0003] At present, the technologies for regeneration of saturated activated carbon mainly in...
