Small refuse incinerator

Abstract

The invention provides a refuse incinerator which comprises a fume spiral channel device, an incinerator body, a hot air gathering slot, a fume exhaust tube and a chimney, wherein the hot air gathering slot is arranged at the bottom of the incinerator body and is fixedly connected with the bottom surface of the incinerator body; the incinerator body comprises an insulating layer and an inner core layer; a space is reserved between the insulating layer and the inner core layer, thus forming a cold air preheating duct; the side wall at the top of the inner core layer is provided with an air hole; the side wall of the upper part of the incinerator body is provided with a feed port; fire bars are arranged on a bottom plate of the incinerator body; the fume spiral channel device is arranged at the top of the incinerator body; a fume spiral channel outer plate and the incinerator body define a fume spiral channel; the chimney is communicated with the fume spiral channel; and the fume exhaust tube is arranged on the side wall of a bottom end. The refuse incinerator has the advantages that the failure rate is low; the service life is long; the problem of influence of coking on fume flow path and oxygen supply in a hearth can be avoided; the refuse incinerating capacity is increased; and the incineration effect is good.

Description

technical field [0001] The invention relates to equipment for harmless treatment of garbage, in particular to a small garbage incinerator. Background technique [0002] With the development of society, the harmless treatment of domestic waste has become an increasingly important issue. At present, the main way to deal with domestic waste is incineration, and the types of waste incinerators are increasing day by day, with more and more functions. In an existing garbage incinerator, a flue connecting up and down is provided in the middle and upper part of the hearth, and several regular smoke outlets are provided at a position parallel to the flue on the hearth, which is connected to the upper flue, and a flue is installed between the upper and lower flues. There are partitions. The lower flue is connected to the total smoke outlet. An oxygen increasing tube is arranged at the lower part of the furnace, that is, at the center of the grate. The feeding port is located on the...
