[0041] Figure 4 It is a schematic diagram of the composition of the garbage incinerator provided by the second embodiment of the present invention, such as Figure 4 As shown, the structure of the garbage incinerator provided by the second embodiment of the present invention is basically the same as that of the garbage incinerator provided by the first embodiment of the present invention. The filtering mechanism includes a partition 25 which is perpendicular to the axis of the casing and tightly combined with the inner wall of the casing. A smoke through hole 25 is arranged in the center of the partition 25 in the axial direction, and a smoke exhaust cap 26 is arranged on the through hole 25 . Because the present invention is equipped with a filter mechanism, the dust rolled up due to the swirling flow formed by the air supply device in the incineration chamber falls back into the incineration chamber, so that the inner chamber of the waste heat boiler and the heat exchanger ...

Abstract

The invention provides a garbage incinerator, and belongs to the technical field of waste treatment. The garbage incinerator comprises a shell, an air supply device, and further comprises a rotating bed arranged inside the incinerator shell, wherein through holes are formed in the center of the rotating bed along the axial direction; the air supply device comprise an exhausting grid cover, an airsupply casing pipe, a first air supply pipe and a valve ball; the air supply casing pipe sequentially comprises exhausting grid barrels; the cross-sectional areas of the exhausting grid barrels are sequentially reduced to form a section for accommodating the cavity of the valve ball and a cylindrical section for insertion of the air supply pipe; the exhausting grid cover comprises a convex cover and exhausting grid barrels which are arranged at the lower end of the convex cover, are parallel to the axial direction of the convex cover and are cylindrically distributed; the exhausting grid barrels of the exhausting grid cover are movably connected to the exhausting grid barrels of the air supply casing pipe; and the first air supply pipe is inserted in the cylindrical section of the air supply casing pipe. The garbage incinerator provided by the invention can continuously and stably burn at a high temperature, can prevent the generation of harmful gases, and has a fast incineration speed; and unburned components in ash are few.

Description

technical field [0001] The invention relates to a garbage incinerator, which belongs to the technical field of waste treatment. Background technique [0002] In recent years, incinerators for general waste such as municipal waste and household waste have attracted social attention. This is because dioxins are generated when wastes containing chlorine are incinerated, and this is an important environmental problem. The countermeasure to solve this problem is to ensure that the burning temperature of waste is high temperature and the holding time at high temperature is set for a long time. As a result, an incinerator capable of securing a combustion temperature of 800° C. or higher is required. The incinerators provided in the prior art are supplied with gas from the side wall of the furnace, so that the garbage in the center of the hearth is burned at a low temperature, or only the gas is supplied from the center of the furnace, so that the garbage at the periphery of the h...
