Technical Field

[0001] This invention relates to the field of combustion equipment, and more specifically to a swirl burner. Background Technology

[0002] Gas burners use natural gas and other gases as fuel and are characterized by complete combustion, high combustion temperature, and easy combustion control. They are widely used in various industries, such as petrochemicals, building materials, power, textiles, printing and dyeing, steel, metallurgy, machinery, and food.

[0003] In the waste gas treatment industry, traditional burners require additional combustion air, which significantly interferes with the flow of waste gas. Removing the combustion air, however, hinders complete combustion and fails to achieve the desired treatment effect. For waste gas treatment manufacturers, resolving the combustion air interference issue and improving combustion completeness has become a pressing problem. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a novel swirl burner. Compared to traditional exhaust gas treatment methods that require additional combustion air, this solution eliminates the need for combustion air ducts. When the exhaust gas flows into the combustion chamber, it is a combustible exhaust gas containing oxygen, effectively avoiding the problem of combustion air interference.

[0005] Specifically, this invention proposes a swirl burner, comprising:

[0006] An ignition chamber having a first inner cavity and a communicating hole communicating with the first inner cavity;

[0015] A guide tube, with second guide openings through both ends of the guide tube, one end of the guide tube being fixed to the fixing plate, and the other end of the guide tube passing through the insulation layer and the first inner cavity and installed on the inner wall of the ignition chamber;

[0016] The second gas pipe is slidably disposed in the guide pipe, with the inlet end of the second gas pipe located on one side of the ignition chamber in the direction of the insulation layer, and the outlet end of the second gas pipe extending into the combustion chamber.

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] like Figures 1 to 5 As shown, the swirl burner proposed in this embodiment includes:

[0041] Ignition chamber 11, wherein the ignition chamber 11 has a first inner cavity 12, and the ignition chamber 11 is provided with a communication hole 13 that communicates with the first inner cavity 12;

[0042] Ignition assembly 14, the ignition end of which is inserted into the first inner cavity 12 of the ignition chamber 11;

[0043] Combustion chamber 15, which is fixed to one end of ignition chamber 11, and a through hole 16 and an installation port are provided between combustion chamber 15 and ignition chamber 11;

[0044] A gas supply assembly 18, the gas supply end of which passes through the ignition chamber 11 and the mounting port and extends into the combustion chamber 15.

[0045] This solution proposes a novel swirl burner structure. Compared to the traditional exhaust gas treatment methods in existing technologies that require additional combustion air, this solution does not require the installation of combustion air ducts. When the gas flows into the combustion chamber 15, the gas is combustible exhaust gas containing oxygen, which can effectively avoid the problem of interference from combustion air.

[0046] In one embodiment of this invention, an insulation layer 19 is fixed to the end of the ignition chamber 11 away from the combustion chamber 15, and a fixing plate 20 is provided at the end of the insulation layer 19 away from the ignition chamber 11. This solution uses the insulation layer 19 to block heat transfer, preventing the temperature on the fixing plate 20 from becoming too high, and preventing the temperature of the ignition chamber 11 from affecting the external gas supply pipe.

[0047] As one embodiment of this invention, the ignition assembly 14 includes:

[0048] The first gas pipe 21 has an inlet end and an outlet end. The inlet end of the first gas pipe 21 is located on the side of the fixing plate 20 away from the insulation layer 19. The outlet end of the first gas pipe 21 passes through the insulation layer 19 and extends into the first inner cavity 12.

[0049] Ignition gun 22, which is located in the first inner cavity 12 and is installed at the gas outlet of the first gas pipe 21.

[0050] The technical advantage of this solution is that the ignition gas flows into the inlet end of the first gas pipe 21 and continues to flow into the ignition chamber 11 through the outlet end of the first gas pipe 21.

[0051] As one embodiment of this invention, the gas supply component 18 includes:

[0052] The guide tube 23 has a second guide port 24 through both ends, and one end of the guide tube 23 is fixed on the fixing plate 20. The other end of the guide tube 23 passes through the insulation layer 19 and the first inner cavity 12 and is installed on the inner wall of the ignition chamber 11.

[0053] The second gas pipe 25 is slidably disposed in the guide pipe 23. The inlet end of the second gas pipe 25 is located on one side of the ignition chamber 11, which is perpendicular to the insulation layer 19, and the outlet end of the second gas pipe 25 extends into the combustion chamber 15.

[0054] The technical advantage of this solution is that the length of the second gas pipe 25 extending into the combustion chamber 15 is adjustable. The length of the second gas pipe 25 can be adjusted according to the specific usage environment to ensure that the exhaust gas in the second gas pipe 25 can be fully combusted.

[0055] As one embodiment of this invention, the outlet end of the second gas pipe 25 is provided with a plurality of vent holes 26, which are used for gas to flow into the combustion chamber 15.

[0056] Furthermore, the vents 26 are evenly arrayed with respect to the axis of the second gas pipe 25, so that the combustion gas can flow evenly into the combustion chamber 15.

[0057] As one embodiment of this example, the diameter of the second guide port 24 of the guide tube 23 is larger than the outer diameter of the second gas pipe 25, and the guide tube 23 is provided with a flow through hole 27, which is used to connect the second guide port 24 and the first inner cavity 12.

[0058] The technical effect of this solution is that it allows a portion of the gas in the ignition chamber 11 to enter the second guide port 24 through the flow through hole 27 and flow into the combustion chamber 15.

[0059] As one embodiment of this invention, the fixing plate 20 is provided with one or more combinations of a fire-viewing mirror 28, a hanging lug 29, and a handle 30.

[0060] In one embodiment of this invention, the combustion chamber 15 is frustum-shaped. Based on its frustum-shaped structure, the combustion chamber 15 has an upper bottom surface, a lower bottom surface, and a side surface. The upper bottom surface is a circular surface with a smaller diameter, the lower bottom surface is a circular surface with a larger diameter, and the side surfaces are curved. Both the upper and lower bottom surfaces are open structures. The upper bottom surface is mounted on the ignition chamber 11, and the lower bottom surface is the side of the combustion chamber 15 away from the ignition chamber 11. A swirling air outlet unit is provided on the side wall of the combustion chamber 15, wherein the side wall of the combustion chamber 15 is the side surface of the combustion chamber 15.

[0061] In this design, the upper and lower bases are not actually upper or lower positions. Based on geometric terminology, the basic structure of a frustum consists of an upper base, a lower base, and a side surface.

[0062] The gas flows from the upper bottom surface to the lower bottom surface in the combustion chamber 15.

[0063] The swirl air outlet unit consists of several groups of air outlets 31. Each group of air outlets 31 has multiple outlets, and each group of air outlets 31 is arranged in a uniform circumferential array with the axis of the combustion chamber 15 as the reference.

[0064] As one embodiment of this invention, each of the air outlets 31 is provided with a guide plate 17 at its edge, and the guide plate 17 is fixed on the inner wall of the combustion chamber 15.

[0065] Furthermore, the tangent at the connection between the deflector 17 and the combustion chamber 15, and the angle between the tangent and the deflector 17, gradually increase or decrease in a clockwise direction.

[0066] Furthermore, the burner is made entirely of corrosion-resistant materials to prevent damage from corrosive components in the gas.

[0067] Furthermore, the ignition gun 22 forms a separate enclosed structure through the ignition chamber 11, which can prevent the swirling process wind from affecting the flame.

[0068] Furthermore, the combustion chamber 15 of this design has a frustum-shaped structure, which allows process air to flow into the combustion chamber 15, and the swirling structure increases the stability of the flame.

[0069] Furthermore, the gas supply assembly 18 adopts a packing seal structure, which allows for adjustment of the position of the second gas pipe 25 while ensuring the sealing performance of the connection.

[0070] This solution is suitable for waste gas treatment applications, utilizing the oxygen in the waste gas for combustion without the need for additional combustion air configuration.

[0071] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
