[0015] The present invention is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the present invention. The methods used in the present invention are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0016] like Figure 1-3 As shown, the present invention provides an incinerator with sufficient combustion, comprising a furnace 1, the top of which is provided with arch bricks 2, which are reinforced by arch brick supports 3. The arch bricks 2 can better share the pressure on the top of the furnace 1, avoiding structural deformation caused by the pressure of the high-temperature gas in the furnace 1. The curved structure can disperse external pressure through the arch, reducing the problem of local stress concentration, and making the top of the furnace 1 have a higher load-bearing capacity. A ring beam 4 is also provided above the furnace 1. The ring beam 4 is made of concrete. The ring beam 4 serves as a load-bearing and connecting structure, which can prevent uneven deformation of the furnace 1 wall, effectively disperse and balance the pressure, avoid excessive wall deformation, and ensure the long-term stability of the furnace 1. A furnace door 17 is provided on the front of the furnace 1, and a secondary flue 7 is added on the back. The secondary flue duct 7 is connected to the furnace 1 through a first flue gas outlet 18 located in the upper half of the furnace 1, extending the flow distance of the flue gas, increasing the combustion time of the flue gas, and ensuring more complete flue gas combustion. The bottom of the furnace 1 is separated and filtered by a grid 5 to allow the ash to fall into the ash hopper 6.

[0017] The furnace 1 also includes a blower 8, the air outlet of which is connected to a combustion-supporting air supply system 9. The combustion-supporting air supply system 9 has multiple air supply branch units. The furnace 1 is provided with multiple air supply branch units on three sides except for one side of the furnace door 17. The air supply branch units include an ash hopper air supply unit 10, a furnace downwind unit 11, a furnace upwind unit 12, an upper smoke elimination unit 13, and a lower smoke elimination unit 14. The ash hopper air supply unit 10 is composed of a plurality of pipes extending from an air supply pipe to the interior of the furnace 1 and then extending to the ash collecting hopper 6 at the bottom of the furnace 1, so as to supply air to the unburned ash in the ash collecting hopper 6 for combustion assistance; the furnace downwind unit 11 is composed of a plurality of air supply pipes extending to the lower half of the furnace 1, so as to supply air to the incineration materials at the bottom of the furnace 1 for combustion assistance; the furnace upwind unit 12 is composed of a plurality of air supply pipes extending to the upper half of the furnace 1, so as to supply air to the flue gas generated above the furnace 1 for combustion assistance; the upper smoke elimination unit 13 is composed of a plurality of air supply pipes extending to the upper half of the auxiliary flue 7, so as to supply air to the upper flue gas entering the auxiliary flue 7 for combustion assistance; the lower smoke elimination unit 14 is composed of a plurality of air supply pipes extending to the lower half of the auxiliary flue 7, so as to supply air to the lower flue gas entering the auxiliary flue 7 for combustion assistance.

[0018] It also includes a chimney 15, which is connected to the auxiliary flue 7 through a second flue gas outlet 19. An ejector seat 16 is provided at the bottom of the chimney 15. The ejector in the ejector seat 16 reduces the accumulation of flue gas during the discharge process, reduces the retention of smoke and harmful gases near the chimney 15, helps to improve the air quality near the furnace 1 and reduce air pollution.

[0019] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] However, the above description is merely a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
