Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste incineration equipment, and particularly relates to a waste incinerator. BACKGROUND

[0002] Life garbage disposal is an important part of city management and environmental protection, and is an important symbol of social civilization, and is related to the vital interests of the people. Incineration is the main way of city life garbage disposal at present. Incineration of garbage can achieve the three goals of harmlessness, reduction and resource utilization. At present, the grate type incinerator is mainly used for incineration of municipal solid waste in China. In order to make the garbage with high moisture content and high ash content burn steadily, a high-quality and efficient incinerator combustion device plays a crucial role.

[0003] In the prior art, a waste incinerator combustion device is disclosed in Chinese patent document No. CN212644614U, which comprises a furnace body for incinerating waste inside, a plurality of inclined grates are installed in the furnace body, all the grates are arranged in a stepped manner, and an ash collector is arranged below the outlet of the bottom layer of the grates; a feed inlet for feeding garbage is arranged on the furnace body, and a feed hopper for guiding garbage is arranged at the feed inlet; a pusher for pushing garbage is arranged below the feed inlet, and the outlet end of the pusher is located above the top end of the top layer of the grates; a residue discharge hopper is arranged below each of the grates, the top of the residue discharge hopper is an ash inlet and is opposite to the bottom of the grate, the middle of the residue discharge hopper is connected to an air distribution mechanism for feeding air, and the bottom of the residue discharge hopper is an ash outlet for discharging ash. A pilot burner is arranged above the top layer of the grates on the furnace body, and an auxiliary burner is further arranged on the furnace wall of the furnace body. When the incinerator is started, the garbage in the furnace is burned by the pilot burner and the auxiliary burner, which can effectively reduce the generation of dioxin during the start-up of the furnace, thereby reducing environmental pollution.

[0004] In the above-mentioned waste incinerator combustion device, the garbage is ignited by the pilot burner and the auxiliary burner at the upper part of the inclined grates, and then the burning garbage is pushed obliquely downward through the inclined grates. The garbage is burned out when it reaches the bottom of the inclined grates, and finally enters the ash collector. In this process, the burning garbage is pushed obliquely downward, so the high-temperature environment of the upper space of the inclined grates cannot be maintained, and the next batch of garbage to be burned is pushed into the upper part of the inclined grates, which contains high moisture content and low calorific value. The heat of the upper space of the inclined grates is absorbed by the garbage to be burned, thereby further reducing the temperature of the upper space of the inclined grates, resulting in a gradual decrease in the temperature of the upper space of the inclined grates. The garbage in this area cannot be ignited, and the garbage burns insufficiently in the incinerator, resulting in low efficiency of garbage disposal and incomplete elimination of toxic and harmful substances in the garbage. The incineration of waste into the air pollutes the environment. SUMMARY
