[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The waste incinerator of this utility model embodiment will now be described with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the waste incinerator of this utility model embodiment may include a furnace body 10, a water tank 20, a gas supply assembly 40, a filter assembly 50, and a cleaning assembly 60. The top surface of the furnace body 10 is connected to an exhaust pipe 11, a support plate 12 is provided on one side of the furnace body 10, the water tank 20 is installed on the support plate 12, a heat exchange pipe 21 is provided inside the water tank 20, the two ends of the heat exchange pipe 21 pass through the two side walls of the water tank 20 respectively, the exhaust pipe 11 is connected to one end of the heat exchange pipe 21, a solenoid valve 22 is provided at the end of the heat exchange pipe 21, and a drainage assembly 23 is provided on the bottom surface of the water tank 20.

[0022] It should be noted that the exhaust pipe 11 is made of high-temperature resistant material and can withstand the high-temperature flue gas generated by waste incineration. The top surface of the water tank 20 is provided with a water inlet, which makes it convenient for staff to add water to the water tank 20. The water inlet is covered to prevent the water in the water tank 20 from being contaminated by the outside. The flue gas flow of the heat exchange tube 21 can be controlled by the solenoid valve 22, and the flue gas flow can be adjusted or the heat exchange can be stopped as needed.

[0023] The drainage component 23 is positioned separately from the filter box 31, making it easier for staff to collect hot water from the water tank 20 using collection equipment.

[0024] A support plate 13 is provided on one side of the furnace body 10. A filter box 31 and a fan 32 are provided on the support plate 13. The input end of the fan 32 is connected to the filter box 31. One end of the gas supply component 40 is connected to the heat exchange tube 21, and the other end is connected to the filter box 31. The filter component 50 is set inside the filter box 31, and the cleaning component 60 is set on the filter component 50.

[0025] It should be noted that the filter box 31 described in this embodiment is equipped with a pressure relief device, which automatically opens when the pressure exceeds a set threshold to release the excessive pressure.

[0026] Specifically, the staff first open the lid of the water tank 20 and add water to the water tank 20. After adding water, the garbage is introduced into the furnace body 10 for incineration. Then, the solenoid valve 22 is activated, and the high-temperature flue gas generated by the furnace body 10 enters the heat exchange tube 21 through the exhaust pipe 11. The heat exchange tube 21 transfers heat to the water in the water tank, realizing the cooling of the flue gas and the recovery of waste heat. The staff can operate the drainage component 23 to discharge hot water to meet the heating needs of the employees' domestic water (such as washing and cleaning) in the waste incineration plant area, reducing the energy consumption of additional hot water preparation.

[0027] When the fan 32 is started, the suction generated at the input end of the fan 32 will transport the cooled flue gas through the gas delivery component 40 to the filter box 31. The flue gas will be filtered and purified by the filter component 50. At the same time, the cleaning component 60 will be started to clean the particulate matter attached to the filter component 50 to prevent the filter component 50 from becoming clogged and affecting the filtration effect. The filtered flue gas will be discharged through the output end of the fan 32.

[0028] The waste incinerator of this utility model can cool down and recover waste heat from the high-temperature flue gas generated by waste incineration. While significantly extending the service life of the filter components, it achieves efficient energy utilization and avoids potential energy waste.

[0029] In one embodiment of this utility model, such as Figure 1 As shown, the gas delivery assembly 40 includes a gas delivery pipe 41 and an air inlet hood 42. One end of the gas delivery pipe 41 is connected to the heat exchange pipe 21, and the other end of the gas delivery pipe 41 is connected to the air inlet hood 42. The air inlet hood 42 is connected to the filter box 31.

[0030] It should be noted that the cooled flue gas can be guided from the heat exchange tube 21 to the air inlet hood 42 through the gas supply pipe 41. The air inlet hood 42 reduces the airflow impact by increasing the flow area, so that the flue gas enters the filter box 31 in a stable state.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the filter assembly 50 includes a mounting frame 51, an activated carbon adsorption mesh 52, and a filter mesh 53. The mounting frame 51 and the activated carbon adsorption mesh 52 are respectively disposed in the filter box 31, and the filter mesh 53 is disposed in the mounting frame 51. The filter mesh 53 is circular.

[0032] It should be noted that both the mounting bracket 51 and the activated carbon adsorption net 52 are installed in the filter box 31 with screws, and can be disassembled for maintenance. After the flue gas enters the filter box 31, the filter net 53 intercepts particulate matter (such as ash and dust) in the flue gas, and the flue gas is purified by physical filtration. Then, the activated carbon adsorption net 52 adsorbs harmful gases and odors in the flue gas, and the flue gas is discharged through the output end of the fan 32.

[0033] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the cleaning assembly 60 includes a driver 61, a connecting bracket 62, a bolt 63, and a cleaning brush 64. The driver 61 is located at the center of the filter screen 53, the connecting bracket 62 is located at the output end of the driver 61, the bolt 63 is located on the connecting bracket 62, and the bolt 63 is threadedly connected to the cleaning brush 64, which is in contact with the filter screen 53.

[0034] It should be noted that the driver 61 described in this embodiment can be a motor. The driver 61 can drive the cleaning brush 64 to rotate. During the rotation of the cleaning brush 64, the particulate matter on the filter screen 53 is cleaned to prevent the filter screen 53 from becoming clogged. When the cleaning brush 64 needs to be disassembled for maintenance, the operator opens the door of the filter box 31 and uses a screwdriver to loosen the bolt 63 to separate the cleaning brush 64 from the connecting frame 62, thus completing the disassembly of the cleaning brush 64. The operator needs to open the filter box 31 periodically and use cleaning tools to clean the impurities accumulated on the bottom wall of the filter box 31.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, the drainage assembly 23 includes a drain pipe 231 and a drain valve 232. The drain pipe 231 is connected to the bottom surface of the water tank 20 and passes through the support plate 12. The drain valve 232 is installed on the drain pipe 231.

[0036] Understandably, staff can operate drain valve 232 to control the opening and closing of drain pipe 231, thereby draining hot water from water tank 20 for use by factory employees.

[0037] In summary, the waste incinerator of this utility model embodiment can cool down the high-temperature flue gas generated by waste incineration and recover waste heat, which significantly extends the service life of the filter components, achieves efficient energy utilization, and avoids potential energy waste.
