Bulk material type sludge thermal treatment carbonization furnace

Abstract

The invention discloses a bulk material type sludge thermal treatment carbonization furnace which comprises a carbonization furnace body, wherein the carbonization furnace body comprises an outer furnace body and an inner furnace body which is rotationally connected inside the outer furnace body; a material cavity is formed inside the inner furnace body; a bulk material component is assembled inside the material cavity; the bulk material component comprises a transverse beam rod; end parts of the transverse beam rod is fixedly connected with the inner wall of the material cavity; a plurality of bulk material plates are hinged with the transverse beam rod; the bulk material plates are axially distributed on the transverse beam rod; and the bulk material plates are radially distributed on the transverse beam rod. By adopting the device disclosed by the invention, the carbonization treatment effect of materials is effectively improved, insufficient material carbonization can be avoided, in addition, the carbonization cycle can be appropriately shortened, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to the field of carbonization furnaces, in particular to a loose material sludge heat treatment carbonization furnace. Background technique [0002] At present, the annual sludge production in my country is about 30 million tons, and the sludge production is expected to reach 60-90 million tons by 2020. With the increasing development of environmental protection and resource utilization technologies at home and abroad, the harmless disposal and resource utilization of sludge has gradually become a new development trend in the field of sludge treatment and disposal. [0003] Sludge carbonization process: The sludge is conditioned, filtered, dried, and carbonized, and the moisture content can be reduced to below 1%. After the final carbonization, the material is widely used, and the sludge reduction, stabilization, harmlessness, and resources are realized. requirements. [0004] The Chinese patent application number is: 2017209510...

AI Technical Summary

Problems solved by technology

[0007] In the initial process of carbonization treatment, the looseness of the material is not high (sludge has a certain strength of bonding characteristics), resulting in the inability to fully conduct heat transfer between the sludge material in the central part and the sludge material in the surrounding parts

[0008] The existence of the above-mentioned technical problems has resulted in an increase in the cycle of carbonized materials and increased energy consumption, and the carbonization effect of the carbonized materials is uneven
