In many industries that require high-temperature heat sources such as metallurgy and chemical industry, the plasma combustion torch wind disc provides stable and reliable heat supply for the production process, helping to improve product quality and production efficiency, and also has positive significance for environmental protection, as good combustion can reduce the generation of harmful gases.
[0003] Traditional combustion devices are usually composed of burners, fuel supply systems, and air supply systems. The fuel supply system delivers natural gas and other fuels to the burner, and the air supply system provides the required air for combustion.

[0004] However, traditional combustion devices have certain deficiencies in gas mixing. During the mixing of natural gas and air, natural gas often cannot be uniformly mixed with air, and local mixing ratio disorders can easily occur. Moreover, when natural gas enters the mixing area, the pressure release is not balanced, causing great disturbance to the stability of the airflow formed during combustion, such as disturbing the normal form of the cyclone airflow, leading to unstable combustion, reducing combustion efficiency, increasing energy consumption and pollutant emissions, and failing to meet the strict requirements of modern industry for efficient and clean combustion.

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0024] Reference Figs. 1-3The utility model provides an embodiment: a kind of plasma combustion torch air disc, including air disc body 1, multiple gas horizontal hole one 3 and gas horizontal hole two 6 are set in air disc body 1 side wall, gas horizontal hole one 3 and gas horizontal hole two 6 between symmetric distribution, and gas horizontal hole one 3 aperture is greater than gas horizontal hole two 6 aperture, gas horizontal hole one 3 and gas horizontal hole two 6 are all forty-five degree inclined hole, for guiding the mixing between natural gas and air, larger aperture gas horizontal hole one 3 can make more amount of natural gas quickly enter mixing area, and air is formed with the preliminary mixed state, and the aperture smaller gas horizontal hole two 6 can fine tune the flow of natural gas, so that natural gas is mixed with air with more suitable proportion, forty-five degree inclined hole design is favorable to change the injection direction of natural gas, so that its contact with air is more sufficient, promotes even mixing between both, provides good prerequisite for high efficiency combustion, in the equipment production manufacturing process, the inclination angle of gas horizontal hole one 3 and gas horizontal hole two 6 can be adjusted according to kiln burner range, to meet different use demands, air disc body 1 top is fixedly connected with connecting column 4, connecting column 4 plays the role of firm air disc body 1, it can be connected with other relevant components and fixed, ensure that the position of air disc body 1 in whole device is stable, avoid displacement or sway due to factors such as vibration or air flow impact in working process, so as to guarantee that gas horizontal hole one 3, gas horizontal hole two 6 and other structures can continue normal work, maintain stable gas and air mixing and combustion process, multiple connecting holes 5 are set in air disc body 1 inside, connecting hole 5 is annular array in air disc body 1 inside, the aperture of outward side connecting hole 5 is greater than the aperture of inward side connecting hole 5, connecting hole 5 is used to guide natural gas to enter the inside of air disc body 1, multiple guide grooves 2 are set in the inner side wall of air disc body 1 outer wall, guide groove 2 is forty-five degree inclined groove, guide groove 2 is located on the side of gas horizontal hole one 3 and gas horizontal hole two 6, guide groove 2 is used to guide air flow direction, promote air accelerated flow, the forty-five degree inclined groove of guide groove 2 is designed, can effectively change the flow direction of air according to aerodynamics principle, so that it is with specific angle and speed to the natural gas that the natural gas that gas horizontal hole one 3 and gas horizontal hole two 6 spouts, accelerate the collision and mixing of air and natural gas, so that mixed gas reaches better mixing uniformity before entering combustion area, improve the fullness and efficiency of combustion, reduce the occurrence of incomplete combustion and other adverse phenomena;
[0025] Specifically, during the operation of the device, natural gas enters the flow guide groove 2 through the gas horizontal hole 1 and the gas horizontal hole 2. The design of the two holes can effectively control the inflow mode and pressure distribution of natural gas. The hole diameter of the gas horizontal hole 1 is larger, and the hole diameter of the gas horizontal hole 2 is smaller, which helps to control the change of natural gas flow rate and pressure, so as to achieve the expected gas flow effect. After the natural gas flows through the gas horizontal hole 1, the internal pressure is gradually released and approaches the pressure level of the air, effectively reducing the turbulent flow phenomenon during the natural gas flow, reducing the interference of the gas flow to other components in the device, especially the cyclone. Because the pressure of the natural gas flow is too high, it will adversely affect the operation of the cyclone device. Therefore, controlling the pressure of the natural gas can avoid excessive interference to the cyclone and improve the overall operation efficiency of the device. After the natural gas and air enter the flow guide groove 2, the shape and structure of the flow guide groove 2 can not only effectively guide the direction of the natural gas flow, but also promote the mixing of natural gas and air in advance through a specific flow channel design. The mixing process of natural gas and air can be more uniform and sufficient, further improving the efficiency of combustion. Sufficient gas mixing means that the energy utilization in the combustion process is more efficient, reducing energy waste and making the combustion process more stable.
[0026] Working principle: During the use of the device, natural gas directly enters the inner wall of the flow guide groove 2 from the gas horizontal hole 1 and the gas horizontal hole 2, uses the flow guide groove 2 to guide the flow direction of the air, promotes the mixing of natural gas and air in advance, improves the combustion efficiency, and uses the larger hole diameter of the gas horizontal hole 1 than the gas horizontal hole 2 to further release the pressure of the natural gas, gradually approaches the air pressure, reduces the interference of the natural gas flow to the cyclone, and enhances the gas mixing effect of the device.
[0027] Finally, it should be noted that: the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features.
