A sludge pyrolysis incinerator

Abstract

The invention discloses a sludge pyrolysis incinerator, which comprises a platform and a rotary kiln body that can rotate along its own axis, and the platform is provided with a kiln head cover that is rotatably connected with the kiln head end of the rotary kiln body and is connected with the kiln head end of the rotary kiln body. The kiln tail end of the rotary kiln body is rotatably connected to the kiln tail cover, the bottom of the kiln head cover is provided with a discharge port, the top of the kiln tail cover is provided with an air outlet, and the platform is provided with a gas inlet to the kiln head end of the rotary kiln body. The air inlet pipe mechanism, the inside of the rotary kiln body is equipped with a pyrolysis kiln body that can rotate synchronously with the rotary kiln body. A feeder for feeding into the pyrolysis kiln body and a secondary combustion chamber communicated with the air outlet are arranged on the platform. The invention aims to provide a sludge pyrolysis incinerator which realizes sludge preheating and pyrolysis and improves incineration efficiency.

Description

technical field [0001] The invention belongs to the field of sludge incineration, in particular to a sludge pyrolysis incinerator. Background technique [0002] The usual treatment method for sludge is landfill or incineration. Since landfill needs to occupy a large amount of land and will cause great pollution to the land after landfill, the waste of land resources is relatively serious; incineration is currently the most thorough treatment for sludge. The solution is to dry the sludge after preliminary treatment to reduce the moisture content of the sludge so that it can quickly reach the ignition point and be ignited smoothly. At present, sludge incineration is mainly carried out through fluidized bed or rotary kiln. The fluidized bed has high requirements for the moisture content and particle size of sludge particles, and the cost of sludge treatment is high, which is difficult to adapt to my country's national conditions.

AI Technical Summary

Problems solved by technology

At present, sludge incineration is mainly carried out through fluidized bed or rotary kiln. The fluidized bed has high requirements for the moisture content and particle size of sludge particles, and the cost of sludge treatment is high, which is difficult to adapt to my country's national conditions.

[0003] Chinese patent announcement number CN204006029U discloses a built-in comprehensive sludge drying and incineration system. When incinerating in a rotary kiln, the requirement for the size of sludge particles is relatively low. Due to the high moisture content of sludge, it is necessary to set up a drying box to The sludge is preheated first to reduce the tax rate of the sludge. The overall structure of the device is relatively large, and the energy consumption is high, and the sludge treatment cost is high.
