Garbage incinerator with circular structure

Abstract

The invention discloses a garbage incinerator with a circular structure. The garbage incinerator with the circular structure comprises an incinerator wall and a circular section hearth formed by the incinerator wall in a surrounding mode; a material falling pipe, a fire grate and a primary air supplying unit are arranged in the hearth; the fire grate comprises a middle material falling disc and aplurality of fire grate rings which are arranged around the material falling disc, and the diameters of the fire grate rings are gradually increased; an outlet of the material falling pipe faces the material falling disc of the fire grate; the primary air supplying unit is arranged under the fire grate; and the material falling disc and the fire grate rings of the fire grate both do circular motion, and every two adjacent assemblies of the fire grate do relative motion. According to the garbage incinerator with the circular structure, the occupation area is smaller compared with a garbage incinerator with a square structure, every two adjacent assemblies of the fire grate do relative motion, therefore, garbage is subjected to more shearing force on the fire grate, and the garbage is not prone to being agglomerated and is combusted more fully; the fire grate does not make contact with the incinerator wall in the whole movement process, and therefore the problem that slag is leaked due to fire grate movement can not occur; the fire grate rings do circular motion, and therefore a driving system is simpler; and few slag discharge outlets are arranged, the positions are single, and therefore slag discharge is easier.

Description

technical field [0001] The invention relates to the technical field of environmental protection for garbage utilization, and more specifically, relates to a garbage incinerator with a circular structure. Background technique [0002] With the progress of urbanization in our country and the continuous improvement of people's living standards, more and more urban wastes are produced, and waste incineration power generation is more and more favored by local governments. At present, waste incineration is usually carried out in waste incinerators, and waste incinerators are usually arranged in a square shape, which faces problems such as large slag leakage, serious wear of grate pieces, insufficient waste combustion, complicated slag discharge devices, and large floor space. Contents of the invention [0003] In view of the problems faced by the current square-arranged garbage incinerator structure, such as large amount of slag leakage, serious wear of grate pieces, insufficien...
