As shown in the accompanying drawings, a plurality of upper burners are arranged on the upper combustion plate and are arranged around the upper combustion plate, and a plurality of lower burners are arranged on the lower combustion plate and are arranged around the lower burner. The upper burners and the lower burners can be oil burners, coal burners or electric burners. The upper burners and the lower burners purchase existing equipment and will not be described in detail. After the incineration tower is charged from the top charging port, the added garbage falls on the upper combustion plate and undergoes preliminary combustion. As the charging is continued, the incinerated garbage will fall along the upper leakage hole onto the lower combustion plate and continue to burn on the lower combustion plate. Through the upper and lower incineration chambers, the garbage incineration processing capacity can be improved, and the garbage can be fully burned, which is beneficial to improving the garbage treatment efficiency. Moreover, after the garbage is incinerated, it naturally falls from top to bottom to the bottom of the incineration tower. During the incineration process, no transportation device is required to transport the incinerated garbage, which can simplify the garbage incineration process.

[0024] In this embodiment, the upper combustion disk 11 includes an umbrella-shaped upper disk body 11a, an upper air supply cylinder 11b connected to the middle of the upper disk body, and an upper support frame 11c. The outer diameter of the upper combustion disk is smaller than the inner diameter of the incineration tower. An annular upper leakage hole is formed between the outer circle of the upper combustion disk and the inner circle of the incineration tower. The upper combustion disk is supported on the upper support frame 11c, and the upper support frame is fixed to the inner wall of the incineration tower. A plurality of upper air supply holes 11d are circumferentially distributed on the air supply cylinder. The upper air supply holes 11d are obliquely opened and face the upper surface of the upper disk body 11a. The incineration tower is externally connected to an upper air supply duct 15, and the upper air supply duct is connected to the inner cavity of the upper air supply cylinder. As shown in the accompanying drawings, the opening at the lower end of the upper air supply cylinder is used to connect with the upper air supply duct, the upper disk body is sleeved on the upper air supply cylinder and fixedly connected to the upper air supply cylinder, the upper support frame is a connecting rod fixedly connected to the outer circle of the upper air supply cylinder in a cross-shaped distribution, the upper support frame is clamped between the upper tower body 10a and the middle tower body 10b, and the upper disk body 11a is supported on the upper support frame, the gas in the upper air supply cylinder is guided to the upper surface of the upper disk body through the upper air supply hole 11d, providing sufficient oxygen for the combustion of garbage on the upper disk body, which is beneficial to improving the combustion efficiency, and the upper surface of the upper disk body 11a is a conical surface, which is beneficial to the circumferential diffusion of newly added garbage after falling on the upper disk body and is beneficial to pushing the burned garbage to slide downward through the upper leakage hole and fall on the lower combustion disk. The taper of the upper disk body 11a should not be too large to prevent the newly added garbage from sliding along the upper disk body to the upper leakage hole.

[0025] In this embodiment, the lower combustion disk 12 includes an inverted umbrella-shaped lower disk body 12a, a circular hole is opened in the middle of the lower disk body 12a to form a lower leakage hole, the outer circle of the lower disk body is sealed with the inner circle of the incineration tower, the edge of the lower disk body has an upwardly protruding annular retaining edge 12b, the annular retaining edge has an annular wind cavity, the incineration tower is connected to the outside of the lower air supply pipe 16, the lower air supply pipe is connected to the annular wind cavity, and a plurality of lower air supply holes 12c are circumferentially distributed on the inner circle of the retaining edge, and the lower air supply holes are obliquely arranged and face the upper surface of the lower disk body. As shown in the accompanying drawings, the upper plate and the lower plate are coaxially arranged, and the garbage falling through the upper leakage hole falls on the periphery of the lower plate. The fresh air introduced into the lower air supply pipe 16 enters the annular wind cavity and flows circumferentially toward the upper surface of the lower plate through the lower air supply hole, providing sufficient oxygen for the incineration of the garbage on the lower plate. The garbage on the upper combustion plate falls on the periphery of the lower plate through the upper leakage hole, preventing the fallen garbage from directly falling on the bottom of the incineration tower through the lower leakage hole. The garbage above continuously falls on the periphery of the lower plate and pushes the incinerated garbage on the lower plate to slide along the conical surface toward the center and fall through the lower leakage hole. The taper of the lower plate should not be too large to prevent the fallen garbage from sliding along the lower plate to the lower leakage hole. Through the cooperation of the upper combustion plate and the lower combustion plate, the added garbage diffuses outward from the center of the upper combustion plate and falls on the periphery of the lower combustion plate, and then gathers at the center of the lower combustion plate and falls on the bottom of the incineration tower. The garbage radially returns on the upper and lower combustion plates to increase the incineration path of the garbage. During the garbage transfer process, it is beneficial to the turning of the garbage, improve the garbage incineration efficiency, and facilitate the full combustion of the garbage.

[0026] In this embodiment, a buffer plate 17 is also included in the incineration tower. The buffer plate is located below the lower combustion plate 12. The buffer plate 17 includes an outer ring 17a and a buffer strip 17b radially connected to the outer ring. The buffer strip is a steel strip. As shown in the attached drawings, the buffer plate is coaxially arranged with the lower combustion plate. The ash falling from the lower combustion plate can be buffered by the buffer plate to reduce the impact of the fall. Moreover, the radial buffer strip is conducive to cutting the larger block ash falling down to reduce the particle size of the ash, which is conducive to the subsequent treatment process of the ash.

[0027] In this embodiment, the upper combustion disk further comprises a plurality of partition plates 11e connected to the upper surface of the upper disk body, and each partition plate is evenly distributed circumferentially to divide the upper part of the upper disk body into a plurality of fan-shaped incineration zones, and the upper air supply cylinder is used to ventilate each fan-shaped incineration zone through the upper air supply hole 11d. Each fan-shaped incineration zone has a corresponding air supply hole to ensure that fresh air can be supplied to the corresponding incineration zone. Fresh air is directly supplied to the incineration zone, which is beneficial to improve the combustion efficiency, and the partition plates are beneficial to the circumferential uniform distribution of garbage, which prevents garbage accumulation and improves the garbage combustion efficiency.
