[0005] The ultra-low emission high-efficiency flame-stabilizing gas combustion equipment provided in this application adopts the following technical solution:

[0007] By adopting the above technical solution, the first fan provides power to discharge the smoke from the coal combustion furnace and the garbage incinerator through the exhaust pipe. When coal is added to the coal combustion furnace, the opening and closing component is in an open state; when the addition is completed, the opening and closing component is in a closed state, so that the oxygen in the coal combustion furnace is reduced, so that the coal and garbage can be fully burned, and the content of harmful gases that are not fully burned is reduced.

[0008] Optionally, the opening and closing assembly includes a sealing plate and a driving device for driving the sealing plate to move up and down.

[0009] By adopting the above technical solution, the driving device controls the sealing plate to move up and down, thereby connecting or closing the feed pipe, which has the beneficial effect of facilitating the opening and closing of the feed pipe.

[0010] Optionally, the driving device includes a connecting rod, a first sliding rod, a second sliding rod, a spring, a fixed platform fixed to the outside world, and a first motor fixed to the outside world, the output shaft of the first motor is fixedly connected to the first gear, the upper surface of the fixed platform is rotatably connected to the second gear, the first gear and the second gear are meshed with each other, the cross-sections of the first sliding rod and the second sliding rod are both quadrilaterals, the first sliding rod slides up and down in a vertical direction relative to the second sliding rod, the second sliding rod is provided with a sliding hole for the first sliding rod to be inserted, the second gear is provided with a through hole for the second sliding rod to be inserted, the top of the first sliding rod is fixed to the sealing plate, and the second gear is fixed with a ramp platform, the connecting rod is vertically arranged and one end of the connecting rod is fixed to the first sliding rod, the other end of the connecting rod abuts against the ramp platform, one end of the spring is connected to the connecting rod, and the other end of the spring is fixedly connected to the fixed platform.

[0011] By adopting the above technical solution, when the first motor is working, the output shaft of the first motor drives the first gear to rotate, and the first gear drives the second gear to rotate. Under the action of the spring, the connecting rod is always against the top of the inclined table, and in the process of rotation of the first gear and the second gear, the connecting rod will be driven to move up and down against the top of the inclined table. The connecting rod drives the first slide bar to slide up and down along the second slide bar, thereby driving the sealing plate to close or connect the feed pipe.

[0012] Optionally, a first sealing block is provided at the top of the sealing plate, and a second sealing block is provided at the bottom of the sealing plate. A stepped groove is provided on the side of the feed pipe close to the first sealing block. When the sealing plate is located at the upper limit position, the first sealing block is located above the feed pipe, and the second sealing block is located below the feed pipe. When the sealing plate is located at the lower limit position, the bottom wall of the first sealing block abuts against the inner wall of the feed pipe.

[0013] By adopting the above technical solution, the provision of the first sealing block and the second sealing block improves the sealing performance of the feed pipe, making it easy to open and close the feed pipe while preventing the material inside from leaking out.

When the second motor is working, the rotating table is controlled to rotate. During the rotation of the rotating table, the coal enters the feeding channel through the feeding pipe, and finally enters the coal combustion furnace through the feeding pipe, which has the effect of facilitating the addition of coal.

[0016] Optionally, a gas return pipe is connected between the coal combustion furnace and the waste incinerator, and the return pipe is connected to a barrel-shaped fan. The barrel-shaped fan is used to allow the gas in the coal combustion furnace to enter the waste incinerator. The return pipe is connected to a second switch valve for controlling the opening and closing of the return pipe.

[0017] By adopting the above technical solution, the second switch valve is opened and the barrel fan is started to work, and the flue gas in the coal combustion furnace is returned to the garbage incinerator for repeated combustion, which further improves the combustion degree of the flue gas.

[0018] Optionally, a guide pipe is connected between the coal combustion furnace and the waste incinerator, and a flue gas heat exchanger is connected to the guide pipe.

[0019] By adopting the above technical solution, when the first fan is working, the flue gas first enters the coal combustion furnace from the waste incinerator and is finally discharged through the exhaust pipe. The heat of the flue gas is used to heat the air entering the coal combustion furnace. While effectively utilizing the heat of the flue gas, the inlet air temperature in the boiler is also increased, thereby improving the efficiency of the coal combustion furnace.

[0020] Optionally, the feed channel is connected to a limit plate, the limit plate is arranged along the circumference of the turntable and wrapped around the outer side of the turntable, and the limit plate is gap-matched with the turntable.

[0021] By adopting the above technical solution, the setting of the limit plate makes it difficult for the material on the rotating table to fall accidentally, and has the effect of preventing the internal coal from splashing.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] The first fan provides power to discharge the smoke from the coal combustion furnace and the garbage incinerator through the exhaust pipe. When coal is added to the coal combustion furnace, the opening and closing assembly is in an open state; when the addition is completed, the opening and closing assembly is in a closed state, so that the oxygen in the coal combustion furnace is reduced, so that the coal and garbage can be fully burned and the content of harmful gases that are not fully burned is reduced.
