Problems solved by technology

The pyrolysis gasification furnace includes a furnace body in which domestic waste is burned, and an air inlet is provided at the bottom of the furnace body to provide sufficient oxygen during the combustion of domestic waste, and an ash discharge port is provided at the bottom of the furnace body The furnace body falls to the ash discharge port to discharge the ash obtained after combustion. Since there is only a slag discharge roller above the ash discharge port, and the slag discharge roller is always rotating, there is no support for the household garbage that first enters the furnace body. , the burning time is short, it will be directly discharged to the ash discharge port, so that the domestic garbage in the furnace cannot be fully burned and then discharged

Embodiment 1

[0023] Such as Figure 1 to Figure 3 As shown, the present invention proposes a pyrolysis gasification furnace for domestic waste incineration system, comprising: a furnace body 1, the top of which is provided with a distributing device 2 to send domestic waste to the furnace body 1; a secondary combustion furnace 3, It is arranged in the center of the furnace body 1, and an annular combustion chamber 11 is formed between the furnace body 1 and the secondary combustion furnace 3. The secondary combustion furnace 3 is a semi-closed mechanism with an open lower end, and the secondary combustion furnace 3 is a secondary The combustion chamber 31 is provided with a secondary feed port 32 at the top of the secondary combustion furnace 3; the support plate 4 includes a fixed fan-shaped plate 41, a movable fan-shaped plate 42, a first circular plate 43 and a second circular plate 44, the second circular plate 44 The diameters of a circular plate 43 and the second circular plate 44 ar...

Embodiment 2

[0030] The difference between this embodiment and embodiment 1 is: as Figure 5 As shown, in order to prevent the smoke exhaust pipe 5 from being blocked due to the accumulation of a large amount of soot, and to avoid affecting the combustion of domestic garbage in the annular combustion chamber and the secondary combustion chamber, in this embodiment, a There is an ash discharge mechanism 7 for removing soot on the pipe wall of the smoke exhaust pipe 5 .

[0031] In order to set the ash discharge mechanism 7 which is simple in structure and easy to use. The ash discharge mechanism 7 includes: a cleaning ring 71, which is slidably arranged on the wall of the smoke exhaust pipe 5 and is in close contact with the wall of the smoke exhaust pipe 5; a sliding block 72, which is provided with a chute 51 on the wall of the smoke exhaust pipe 5 , the sliding block 72 is fixedly connected with the cleaning ring 71 and can slide in the chute 51, when the wall of the exhaust pipe 5 does...

Abstract

The invention provides a pyrolysis gasifier for a household garbage incineration system. The pyrolysis gasifier comprises a furnace body, a secondary combustion furnace and a support plate, wherein a material distribution device is arranged at the top of the furnace body for conveying household garbage into the furnace body; the secondary combustion furnace is arranged at the centre of the furnace body, an annular combustion hearth is formed between the furnace body and the secondary combustion furnace, the secondary combustion furnace is a semi-closed mechanism with an open lower end, a secondary combustion hearth is arranged in the secondary combustion furnace, and a secondary charge port is formed in the top of the secondary combustion furnace; and the support plate comprises a fixed fan-shaped plate, a movable fan-shaped plate, a first circular plate and a second circular plate, the diameters of the first circular plate and the second circular plate are equal, the diameter of the first circular plate is less than the diameter of the bottom surface of the secondary combustion furnace, the first circular plate is located just below the secondary combustion furnace, and one end of the fixed fan-shaped plate is fixed on the first circular plate. The pyrolysis gasifier provided by the invention has the following beneficial effect: complete combustion of all the household garbage is ensured on the premise of no influence on the discharge of the combusted household garbage.

Description

technical field [0001] The invention relates to domestic waste treatment equipment, in particular to a pyrolysis gasifier for a domestic waste incineration system. Background technique [0002] With the development of science and technology, domestic waste incineration technology is more and more widely used in waste treatment. In order to implement the domestic waste incineration process, a domestic waste incineration system is used in the prior art, and the system includes: a pyrolysis gasifier, a waste heat boiler, an ultrasonic atomization deacidification and dust removal system, and a bag filter. The pyrolysis gasification furnace includes a furnace body in which domestic waste is burned, and an air inlet is provided at the bottom of the furnace body to provide sufficient oxygen during the combustion of domestic waste, and an ash discharge port is provided at the bottom of the furnace body The furnace body falls to the ash discharge port to discharge the ash obtained a...
