Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, in particular to a waste gas purification natural gas combustion device. Background Art

[0002] Existing exhaust gas purification combustion equipment usually includes an exhaust gas inlet, a combustion chamber, an exhaust gas outlet, and a purification device. The combustion chamber of the existing exhaust gas purification combustion equipment is usually large. The large-sized combustion chamber requires more time and space to fully mix the fuel and the exhaust gas. If the mixing is uneven, the fuel concentration in some areas is too high, and the flame density in these areas will increase accordingly, the fuel burns more violently, and more heat is released. This heat will be concentrated in the area with high flame density, causing the temperature of the area to rise rapidly. In the area with low flame density, due to the low fuel concentration, the fuel burns relatively slowly and releases less heat, so the temperature of the area is relatively low, which leads to a decrease in the heat transfer efficiency, and there will be a problem of uneven mixing of fuel and air, which reduces the working efficiency of the burner. Utility Model Content

[0007] Preferably, the inner combustion tube is located inside the outer combustion tube, and one side of the inner combustion tube is fixed to the outer combustion tube.

[0008] The fixed connection between the inner combustion tube and the outer combustion tube can prevent the inner combustion tube from moving or deflecting during the combustion process, thereby ensuring the stability and uniform distribution of the flame. At the same time, this fixed connection can also reduce the vibration and noise generated during the combustion process, and improve the operating efficiency and stability of the equipment.

[0009] Preferably, a delivery pipe 1 is fixed to one side of the combustion outer pipe, and one side of the delivery pipe 1 is the same size as the combustion inner pipe and fits tightly.

[0010] One side of the delivery pipe 1 is the same size as the combustion inner pipe and fits tightly, ensuring that the exhaust gas can smoothly pass through the delivery pipe 1 into the combustion inner pipe and be fully treated during the combustion process. At the same time, the tight fit between the delivery pipe 1 and the combustion inner pipe can reduce the resistance of the exhaust gas during the flow process, improve the efficiency of the exhaust gas treatment, reduce the leakage and loss of the exhaust gas during the flow process, and ensure the safety and reliability of the exhaust gas treatment.

[0011] Preferably, the combustion inner tube is provided with holes, and the holes are provided in different sizes.

[0012] The hole design can increase the contact area between the flame and the inner side of the combustion inner tube, thereby enhancing the combustion effect and improving the combustion efficiency. At the same time, holes of different sizes can make the air and natural gas more evenly distributed when entering the combustion outer tube and the combustion inner tube, further improving the combustion effect, reducing local overheating and extending the service life of the equipment.

[0013] Preferably, a plurality of groups of short tubes are fixed to one side of the connecting plate, and the plurality of groups of short tubes are arranged in a circular shape.

[0014] Preferably, one side of the short tube is connected to an air valve, and the air valve is used to control the flow of air.

[0016] Preferably, one side of the air valve is connected to a delivery pipe 2, and one side of the delivery pipe 2 is connected to a plasma waste gas purifier.

[0017] In the plasma exhaust purifier, harmful substances in the exhaust gas react chemically with the active particles in the plasma and are oxidized, reduced or decomposed into harmless substances. At the same time, the high-energy electrons in the plasma can also collide with the molecules in the exhaust gas to produce more active particles, further promoting the removal of harmful substances.

[0018] Compared with the prior art, the utility model provides a waste gas purification natural gas combustion device, which has the following beneficial effects:

[0019] The burner and the delivery pipe of the utility model both mix the natural gas fuel and the exhaust gas through a plurality of regular holes of different sizes opened on the combustion inner pipe, thereby accelerating the mixing efficiency, and can improve the flame distribution, increase the heat exchange area and improve the air circulation speed, so that the combustion and heating are more uniform, avoid local overheating and improve the thermal efficiency. At the same time, the equipment can efficiently process the harmful substances in the exhaust gas through the combination of the plasma exhaust gas purifier and the burner, decompose them into harmless substances and meet the environmental emission standards. The equipment of the utility model has a simple and clear structure, and the components are tightly connected, which is convenient for disassembly and installation, and easy for maintenance and maintenance.
