Description

Domestic garbage incinerator

Technical Field

The invention belongs to the technical field of garbage incineration, and particularly relates to a household garbage incinerator.

Background

The waste incineration is an old traditional method for treating the waste, and the waste incineration method is one of the main methods for treating the urban waste because the waste is treated by the incineration method, the reduction effect is obvious, the land is saved, various pathogens can be eliminated, and toxic and harmful substances are converted into harmless substances. Modern garbage incinerators are all equipped with good smoke and dust purification devices, and the pollution to the atmosphere is reduced.

Through burning, not only the volume of rubbish reduces greatly, and the volume can reduce 80% after general rubbish burns, can utilize the heat electricity generation that the burning produced, heat supply moreover, reaches energy recuperation's purpose, and the lime-ash after burning can the brickmaking. The waste is complex in composition, and various combustibles in the waste have different densities, shapes, chemical properties, ignition and combustion characteristics, so that the waste can present different combustion speeds and burn-out times in the incinerator, and therefore, the combustion process is difficult to control and the combustion is ensured to be sufficient. In particular, the domestic garbage has large moisture content, is often insufficient and emits black smoke during combustion, wastes energy and causes pollution to the atmosphere.
