Rotary kiln type incineration device capable of fully combusting garbage and collecting waste heat

Abstract

The invention discloses a rotary kiln type incineration device capable of fully combusting garbage and collecting waste heat, and belongs to the technical field of rotary kilns. According to the invention, a scraping mechanism is arranged at the tail end of a rotary kiln; on one hand, garbage and residual ash reaching the tail end of the rotary kiln are separated and treated; on the other hand, caking possibly existing on the inner wall of the tail end of the rotary kiln is scraped; a residual ash collecting mechanism is arranged to sort garbage and residual ash; a residual ash collecting box is sealed by utilizing the high temperature of garbage which is not completely combusted or caked residual ash; therefore, safe treatment is realized; harmful gas emission and air pollution are prevented; garbage which is not completely combusted or caked residual ash can be transferred or placed together with uncombusted garbage through the residual ash collecting box; the uncombusted garbage is preheated and then put into the rotary kiln; at the moment, the preheated garbage can quickly reach the combustion temperature; on the other hand, the residual ash which is not completely combusted is combusted again, and combusting to form residual ash and then discharging.

Description

Technical field [0001] Technical Field The present invention relates to a rotary kiln, in particular refuse combustion apparatus and having a rotary kiln incinerator collected heat. Background technique [0002] With the continuous development of society, garbage and industrial waste are increasing, particularly industrial waste dangerous substance more and more, how to deal with hazardous materials has become a big problem, mainly domestic garbage combustion device spam processing; garbage combustion device mainly by high-temperature combustion of the waste into harmless residue, so that you can meet the requirements of safe emissions; countries attach great importance to hazardous materials handling, issued many relevant policies to encourage the use of rotary kiln incinerator process, rotary kiln original cement kiln, building materials, cement and other disposal facilities, revolving tubular kiln is a kind of a horizontal cylindrical barrel rotatably, the rotational movement ...

AI Technical Summary

Problems solved by technology

[0003] There is a problem with the incineration of garbage through the rotary kiln. The garbage must be fully burned, otherwise the desired purpose will not be achieved; providing sufficient oxygen is the premise of full combustion, which is easy to achieve, but there will still be problems during the combustion process. Many influencing factors affect the combustion effect, such as: the adhesion of the garbage during the combustion process, or insufficient combustion caused by excessive garbage, or the garbage warm-up time is too long due to the slow heating of the garbage, and the garbage cannot be completely burned due to insufficient combustion time; This is the problem we need to solve
