[0027] Embodiment

[0028] Refer to Figures 1-4 For an embodiment of the utility model, a combustion device for industrial waste gas purification is provided, comprising: a combustion unit 100 and an auxiliary unit 200;

[0029] Among them, the combustion unit 100 includes combustion furnace 101 and fixedly connected on the side wall of combustion furnace 101 air inlet pipe 102, the top of combustion furnace 101 is fixedly connected with exhaust pipe 103, the side wall of combustion furnace 101 is fixedly connected with gas supply pipe 104, one end of gas supply pipe 104 penetrates into combustion furnace 101 and is fixedly connected with annular pipe 105, a plurality of combustion nozzles 106 are fixedly connected on the pipe wall of annular pipe 105;

[0030] The auxiliary unit 200 includes electric push rod 201 fixedly installed on the top of combustion furnace 101, the output end of electric push rod 201 penetrates into combustion furnace 101 and is fixedly connected with disc 202, T-shaped rod 203 is rotatably connected to the top of disc 202, the bottom end of T-shaped rod 203 penetrates disc 202 and is fixedly connected with rotating disc 204, a plurality of corresponding round holes 205 are formed in the opposite surfaces of disc 202 and rotating disc 204, two symmetrically distributed protrusions 206 are fixedly connected to the side wall of rotating disc 204, two spiral curved sliding grooves 207 are formed in the inner wall of combustion furnace 101, and the two protrusions 206 are respectively slidably arranged in the two sliding grooves 207.

[0031] Air inlet pipe 102 is used for conveying waste gas into combustion furnace 101, gas supply pipe 104 is used for conveying combustion gas into annular pipe 105, the combustion gas is sprayed out through combustion nozzle 106 and forms high-temperature flame to burn and purify the waste gas, the burned waste gas sequentially passes through the round holes 205 of rotating disc 204 and disc 202, and then is discharged through exhaust pipe 103, when the amount of waste gas is small, electric push rod 201 drives disc 202 to descend, electric push rod 201 is high-temperature resistant, the distribution positions of disc 202 and the round holes 205 of rotating disc 204 are consistent, when rotating disc 204 descends, the two protrusions 206 will respectively slide along the two sliding grooves 207, and the two sliding grooves 207 are both spiral downward curved.

[0032] The slide 207 and the protrusion 206 can drive the turntable 204 to deflect as it descends, so that the turntable 204 and the circular hole 205 of the disc 202 cover each other, allowing a small amount of exhaust gas to pass through the reduced circular hole 205. The turntable 204 and the circular hole 205 of the disc 202 are always connected and not sealed. By driving the disc 202 to descend, the combustion space of the combustion furnace 101 can be compressed. By reducing the amount of exhaust gas passing through the circular hole 205, the residence time of the exhaust gas in the combustion furnace 101 can be increased. This combustion nozzle 106 can fully combust the exhaust gas with low energy consumption, so as to achieve the effect of saving energy.

[0033] In addition, a gas vortex flow meter 107 is fitted on the wall of the exhaust pipe 103, and an inclined plate 108 is fixedly connected to the inner wall of the combustion furnace 101 near the exhaust pipe 103.

[0034] The gas vortex flow meter 107 is a flow measurement instrument for fluid media in industrial pipelines. The gas vortex flow meter 107 can detect the flow rate of exhaust gas, so as to control the electric push rod 201 to drive the disc 202 to rise and fall to a specified height. When the exhaust gas volume is large, the disc 202 rises and the combustion nozzle 106 burns with high heat. When the exhaust gas volume is small, the disc 202 falls and the combustion nozzle 106 burns with low energy consumption. The inclined plate 108 guides the exhaust gas to the bottom of the combustion furnace 101 to prevent the exhaust gas from being blown directly from the side to the flame.

[0035] Furthermore, a water supply pipe 208 is fixedly connected to the side wall of the combustion furnace 101, and a sewage discharge pipe 209 is fixedly connected to the bottom of the combustion furnace 101.

After combustion is completed, the water supply pipe 208 can deliver clean water into the combustion furnace 101. While ensuring that the clean water does not flood the combustion nozzle 106, the ash accumulated in the combustion furnace 101 is discharged with the sewage through the drain pipe 209.

[0037] Furthermore, an annular shell 210 is fixedly connected to the top of the combustion furnace 101. The annular shell 210 is sleeved on the exhaust pipe 103. A water inlet pipe 211 is fixedly connected to the top of the annular shell 210. A drain pipe 212 is fixedly connected to the side wall of the annular shell 210. Valves are sleeved on the walls of both the water inlet pipe 211 and the drain pipe 212. Multiple heat-conducting plates 213 are fixedly connected to the inner wall of the exhaust pipe 103. Both ends of each heat-conducting plate 213 penetrate the exhaust pipe 103 and both ends of each heat-conducting plate 213 penetrate into the inner cavity of the annular shell 210.

[0038] The clean water is added into the annular shell 210 through the water inlet pipe 211, the heat of the exhaust pipe 103 is absorbed through the annular shell 210, the exhaust gas discharged from the exhaust pipe 103 is cooled, the hot water in the annular shell 210 is discharged through the water outlet pipe 212 for secondary use, the heat of the exhaust gas is fully absorbed by the heat-conducting plate 213, and the heat is transmitted to the clean water in the annular shell 210 for heat recycling.

[0039] During use, the clean water is added into the annular shell 210 through the water inlet pipe 211, the exhaust gas is delivered into the combustion furnace 101 through the air inlet pipe 102, the combustion gas is delivered into the annular pipe 105 through the gas supply pipe 104, the combustion gas is sprayed through the combustion nozzle 106 to form a high-temperature flame, the flow of the exhaust gas in the air inlet pipe 102 is detected through the gas vortex flow meter 107, the electric push rod 201 drives the disc 202 to ascend to a specified height, the rotating disc 204 is lowered when the exhaust gas is less, the two protrusions 206 slide along the two sliding grooves 207 to drive the rotating disc 204 to deflect, the rotating disc 204 and the circular hole 205 of the disc 202 are covered with each other, and the small amount of exhaust gas passes through the reduced circular hole 205.

[0040] The combustion space of the combustion furnace 101 is compressed, the amount of exhaust gas passing through the circular hole 205 is reduced, the combustion nozzle 106 fully combusts the exhaust gas at low energy consumption, the heat of the exhaust gas is fully absorbed by the heat-conducting plate 213, and the heat is transmitted to the clean water in the annular shell 210, the hot water in the annular shell 210 is discharged through the water outlet pipe 212 for heat recycling, the water inlet pipe 208 delivers clean water into the combustion furnace 101 after combustion to clean the combustion furnace 101, and the sewage generated by cleaning is discharged through the sewage outlet pipe 209.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
