[0002] With the acceleration of urbanization and population growth, the amount of urban waste continues to increase. Traditional landfill methods face many problems, including limited land resources, leachate contamination of groundwater, and the emission of greenhouse gases such as methane. For example, landfills around some large cities are quickly reaching saturation, and finding new ways to dispose of waste has become a top priority. Against this backdrop, waste incineration power generation, as a treatment method that can achieve waste reduction, harmlessness, and resource utilization, has gradually gained attention.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0020] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0021] The following is combined with Figure 1-4 The present embodiment describes a waste incineration power generation device that is easy to clean, comprising: an incinerator 1, the inner wall of the incinerator 1 being a cylindrical chamber, the top wall of the incinerator 1 being axially connected to an input shaft 2, a burner being provided in the incinerator, a scraper 3 being connected to the input shaft 2, the scraper 3 being in contact with the top and side walls of the incinerator 1, the lower surface of the scraper 3 being in contact with a grate plate 4, the grate plate 4 being connected to the inner wall of the incinerator 1, the lower end of the input shaft 2 passing through the grate plate 4 being connected to a paddle 5, the paddle 5 being in contact with the inner bottom wall of the incinerator 1, an ash discharge pipe 6 being connected to the edge of the lower surface of the incinerator 1, and a screw conveyor 7 and an air inlet pipe 8 being respectively connected to the side walls of the incinerator 1 above the grate plate 4;

[0022] The garbage is transported into the incinerator 1 through the screw conveyor 7, and air is blown into the air inlet pipe 8 through the fan. Since the screw conveyor 7 is blocked by the garbage, the air can only be discharged from the lower ash discharge pipe 6. The garbage is ignited after entering the incinerator 1. The burner can be used to ignite the garbage in the incinerator 1. After the garbage is ignited, it starts to burn under sufficient oxygen supply. The input shaft 2 is turned on to drive the scraper 3 to rotate. The scraper 3 stirs the garbage to fully contact with the air to accelerate combustion. The carbon deposits produced by the combustion adhere to the inner wall of the incinerator 1 and are scraped off by the scraper 3, which will not affect the thermal conductivity of the incinerator 1. The impurities adhered to the scraper 3 fall off when colliding with the garbage and will not be deposited.

[0023] The screw conveyor 7 is arranged perpendicular to the axis of the air inlet pipe 8;

[0024] Prevent direct wind from the air inlet pipe 8 from affecting the discharge of garbage.

[0025] The ash discharge pipe 6 passes through the lower water tank 9, which contacts the bottom wall of the incinerator 1. A water inlet pipe is connected to the side wall of the lower water tank 9. The upper part of the lower water tank 9 is connected to the middle water tank 10, which contacts the side wall of the incinerator 1. The screw conveyor 7 and the air inlet pipe 8 pass through the middle water tank 10. The upper part of the middle water tank 10 is connected to the upper water tank 11, which contacts the top wall of the incinerator 1. The input shaft 2 passes through the upper water tank 11, and the top wall of the upper water tank 11 is connected to the steam pipe 12.

[0026] Water is poured into the lower water tank 9 through the water inlet pipe on the side wall of the lower water tank 9. The high temperature generated by the incinerator 1 burning garbage is conducted to the water through the furnace wall and the water tank wall to boil the water. The incinerator 1 is completely covered by the inside of the water tank, and the heat will not be lost. The evaporated water is discharged through the steam pipe 12.

[0027] The lower water tank 9, the middle water tank 10 and the upper water tank 11 are internally connected with a metal heat-conducting bracket 13;

[0028] A metal heat-conducting bracket 13 is added in the water tank, which not only increases the strength of the water tank but also enhances the heat-conducting performance.

[0029] The input shaft 2 is hollow and connected to the fuel supply system. The outer surface of the input shaft 2 in the incinerator 1 is connected to the ignition nozzle 14.

[0030] After the fuel is injected into the hollow channel of the input shaft 2, it is ignited and ejected through the ignition nozzle 14 to ignite the garbage.
