[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 discloses a waste incineration system, and belongs to the technical field of waste treatment. The system comprises a waste incineration furnace, a waste heat boiler and a separator, wherein the waste heat boiler heats water by utilizing the flue gas produced by the waste incineration furnace; the separator is used for removing dust from the flue gas exhausted from the waste heat boiler; the waste incineration furnace comprises an outer shell and a gas supply device, and also comprises a rotary bed arranged in the outer shell of the furnace; a through hole is formed in the centreof the rotary bed in the axial direction; the gas supply device comprises an exhaust grid cap, a gas supply sleeve, a first gas supply pipe and a valve ball, wherein the gas supply sleeve comprises exhaust grid cylinders, a section and a cylindrical section in sequence, wherein the cross sections of the sections and the cylindrical section are reduced in sequence; the section is used for accommodating the cavity of the valve ball; the cylindrical section is used for the gas supply pipe to insert; the exhaust grid cap comprises a convex cap and the exhaust grid cylinders which are arranged at the lower end of the convex cap and are arranged in a cylinder in the direction parallel to the axial direction of the convex cap; the exhaust grid cylinders of the exhaust grid cap are movably connected to the exhaust grid cylinders of the gas supply sleeve; and the first gas supply pipe is inserted into the cylindrical section of the gas supply sleeve. The waste incineration system provided by the invention can realize continuous high-temperature stable combustion and can prevent the generation of harmful gas; the incineration speed is high; and unburned components in ash are few.

Description

technical field [0001] The invention relates to a garbage incineration system, 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 ...
