Sectional type small-sized garbage incinerator

Abstract

The invention relates to a sectional type small-sized garbage incinerator which comprises an incinerator body. An upper fire grate assembly and a lower fire grate assembly are arranged inside the incinerator body and divide an inner cavity of the incinerator body into three parts including an upper hearth, a lower hearth and an ash pit in sequence from top to bottom. A circular air guide pipe is arranged on the inner side wall of the portion, above the lower hearth, of the incinerator body. Garbage enters the upper hearth, is dried through high-temperature smoke generated by the lower hearth and then enters the lower hearth for combustion. By controlling the smoke flow of the upper hearth and controlling the garbage drying process accordingly, uncontrollable combustion of the garbage in the drying process is avoided. According to the incinerator, garbage is dried at first and then incinerated, so that the garbage combustion process is improved, and the incinerator has better adaptability to garbage with high moisture content and low heat value.

Description

technical field [0001] The invention relates to the field of harmless and reduction disposal of garbage, in particular to a segmented small garbage incinerator. technical background [0002] With the gradual improvement of environmental protection requirements, small incinerators are more and more widely used. Compared with large-scale incinerators, small-scale incinerators have the advantages of low investment cost, simple operation, low requirements for construction sites, and flexible operation. Has good adaptability. Especially for domestic waste in rural areas and sanitation waste in towns and towns, the use of small incinerators for decentralized disposal does not require the construction of special waste transfer stations, nor does it require long-distance transfer of waste. The collected waste can be sent directly to the incineration station. The transfer link and storage time are shortened, and the source of odor emission is reduced. Therefore, small incinerators ...

AI Technical Summary

Problems solved by technology

[0004] For small incinerators, due to various reasons such as investment and operating costs, it is difficult to increase the calorific value of waste by adding auxiliary fuel, and it is also difficult to set up a special leachate discharge tank and build a complex leachate treatment system ;Garbage is generally cleared every day, otherwise the garbage will rot and produce odor, and an odor treatment system needs to be built, so it is difficult to reduce the moisture content by composting for a long time

In addition, small incinerators need to face that the sanitation and cleaning waste in villages and towns will also be sent to the incineration ...
