[0002] Waste incineration is a technology that treats municipal solid waste by burning it at high temperatures. Its core objective is to achieve "reduction, harmlessness, and resource recovery" of waste. It is widely used in densely populated areas with limited land resources. Its core feature is that waste incineration is an advanced urban waste treatment technology that uses high-temperature combustion to completely oxidize the combustible materials in the waste and convert them into harmless ash.
[0003] The incineration of waste releases a large amount of high-temperature waste heat, which is directly discharged into the environment through the chimney. This wastes the heat generated by burning waste and the direct discharge of waste heat can cause the local ambient temperature to rise, which is not good for the environment. Summary of the Invention

Through the feed inlet 11, the waste is fed into the grate 10 inside the incinerator 1 via the feed pipe 9 for complete combustion. The waste releases a large amount of heat energy during combustion. The temperature inside the incinerator 1 is usually maintained above 850℃. The high-temperature flue gas generated by combustion will transfer heat to the water inside the boiler 3 through the water pipe group 4 on the boiler 3. After absorbing heat, the water inside the boiler 3 will turn into saturated steam and superheated steam in sequence. This steam will enter the interior of the steam turbine generator 7 through the recovery pipe 5 and the steam pipe 6, causing the hot steam to drive the impeller of the steam turbine generator 7 to rotate, converting the heat energy of the steam into mechanical energy. The steam turbine generator 7 drives the generator to rotate, converting the mechanical energy into electrical energy. The converted electrical energy can then be used for heating. During waste incineration, the residual heat of leachate can be used for power generation and heating. The leachate in waste incineration can recover the heat carried by the leachate itself through a heat exchange device to achieve heat recycling.

Several crushing blades 18 are fixedly installed on the outer circular wall of the screw rod 17. A discharge pipe 19 is provided on the outer circular wall of the crushing cylinder 13. By setting up the crushing cylinder 13, before the waste is incinerated, the waste to be processed can be poured into the interior of the crushing cylinder 13, and then the drive motor 16 can be started to drive the motor. 16 drives the screw rod 17 and the crushing blades 18 to rotate, crushing and pushing the waste in the crushing cylinder 13. The crushed waste is discharged downward through the discharge pipe 19 and falls into the feed pipe 9, entering the interior of the incinerator 1 for incineration.

The high-temperature chamber 2, the recycling pipe 5 and the steam pipe 6 are made of high-temperature resistant materials. The high-temperature resistant material can be a nickel-based alloy. The alloy type can be nconel 600 / 601 alloy to prevent corrosion from the high-temperature flue gas generated when the waste is incinerated.
[0018] Working principle: Please refer to Figure 1 - Figure 6As shown, by setting up the incinerator 1, before incinerating the waste, the waste to be processed can be poured into the crushing cylinder 13. Then, the drive motor 16 is started, causing the drive motor 16 to drive the screw rod 17 and the crushing blades 18 to rotate, crushing and pushing the waste in the crushing cylinder 13. The crushed waste is discharged downward through the discharge pipe 19 and falls into the feed pipe 9, entering the interior of the incinerator 1 for incineration. This allows the crushed waste to be burned more thoroughly in the incinerator 1. The waste releases a large amount of heat energy during combustion, and the temperature inside the incinerator 1 is usually maintained above 850°C. The high-temperature flue gas produced by combustion... Heat is transferred to the water inside the boiler 3 through the water pipe group 4 on the boiler 3.

During waste incineration, the residual heat of leachate can be used for power generation and heating. The leachate in waste incineration can recover the heat carried by the leachate itself through a heat exchange device to achieve heat recycling.
