The carbonization-activation integrated active carbon sintering device comprises a tubular sintering furnace consisting of a shell, a speed reducer, a furnace body and a hearth; the furnace body is arranged in the shell; the speed reducer is arranged on the shell and is connected with the furnace body through a linkage chain; and a material carbonization area and a material activation area are formed in the hearth, wherein the material carbonization area is provided with a carbonization area air guide port and a carbonization area exhaust port, the material activation area is provided with an activation area air guide port and an activation area exhaust port, and both the outer wall of the furnace body in the material carbonization area and the outer wall of the furnace body in the material activation area are provided with a heating bar connected with a temperature control device. The device can prepare active carbon by using high carbon substances such as agricultural straws, urban waterworks sludge and the like as raw materials, is safe, clean and pollution-free, and solves the problems of insecurity, high pollution and large amount of waste gas produced by combusting and heating water gas in the prior art.

Description

technical field [0001] The invention relates to a carbonization and activation integrated activated carbon sintering device, which belongs to the technical field of activated carbon production equipment. Background technique [0002] Solid wastes such as residual sludge from urban sewage treatment plants and straws from agricultural production are rich in organic carbon sources and can be used as raw materials for the preparation of activated carbon. In today's increasingly scarce resources, the use of surplus sludge and agricultural straw to prepare activated carbon has become a good way to recycle it, and it also provides a new method for solving the problem of solid waste treatment and comprehensive utilization. At present, the commonly used activated carbon preparation methods are chemical method or physical method. The former has a simple production process, but high energy consumption and high pollution; the latter can not carry out the carbonization step and activatio...
