Description

Technical Field

[0001] This invention relates to the field of combustible waste gas combustion treatment technology, and specifically to a swirl-type combustion torch for combustible waste gas combustion treatment. Background Technology

[0002] For combustible organic waste gas generated during industrial production, the usual treatment method is to collect the combustible waste gas through pipelines and then transport it to a combustion system (combustion flare), where it is ignited and burned on a burner, causing the waste gas to react with oxygen in the air and convert the combustible waste gas into CO2 and water.

[0003] For existing combustion flares, air usually reacts with exhaust gas through natural flow. The drawback is that when the exhaust gas volume is large, some exhaust gas is not fully mixed and reacted with air (oxygen), resulting in incomplete combustion and the presence of black smoke after combustion, which affects the compliance of emissions standards. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a swirl-type combustion torch for combustible waste gas combustion treatment, so as to improve the completeness of waste gas combustion.

[0005] The present invention solves the above problems through the following technical means:

[0006] A swirl-type combustion torch for combustible waste gas combustion treatment includes a torch tube, a swirl generating tube rotatably fitted inside the torch tube, and a burner installed inside the swirl generating tube. The side wall of the swirl generating tube is provided with multiple airflow holes, and multiple swirl blades are arranged circumferentially inside the swirl generating tube and above the burner.

[0007] Furthermore, the inner wall of the flare tube is provided with a boss, and the outer wall of the swirl generating tube is provided with an extension edge that overlaps and rotates with the boss.

[0008] Furthermore, ball bearings are fitted between the edge and the boss.

[0009] Furthermore, the air inlet of the burner is connected to the exhaust gas delivery pipe via a quick-release flange.

[0010] Furthermore, the two quick-release flanges are connected by a quick-release ball valve for quick disassembly.

[0011] Furthermore, a heat insulation layer is provided on the inner side of the upper section of the torch tube.

[0012] Furthermore, an air inlet is provided on the lower side wall of the flare tube.

[0013] The beneficial effects of this invention are:

[0014] This application discloses a swirl-type combustion torch for combustible waste gas combustion treatment, comprising a torch tube, a swirl-generating cylinder rotatably fitted inside the torch tube, and a burner installed inside the swirl-generating cylinder. The side wall of the swirl-generating cylinder has multiple airflow holes, and multiple swirl blades are circumferentially arranged inside the swirl-generating cylinder and above the burner. During combustion, the hot airflow in this application drives the swirl-generating cylinder to rotate through the swirl blades, forming a swirl, accelerating airflow, and ensuring thorough mixing with the waste gas, thereby improving the completeness of waste gas combustion. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0018] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] like Figure 1As shown, this invention discloses a swirl-type combustion flare for combustible waste gas combustion treatment, including a flare tube 2, a swirl generating tube 8 rotatably fitted inside the flare tube, and a burner 7 installed inside the swirl generating tube. The burner can be divided into inner and outer rings to increase the combustion area and allow the exhaust gas to fully contact and burn with the air. The specific form of the swirl generating tube and the flare tube assembly is as follows: the inner side wall of the flare tube is provided with a boss 11, and the outer side wall of the swirl generating tube is provided with an extension 12 that overlaps and rotatably fits with the boss. A ball bearing 10 is fitted between the extension and the boss.

[0021] The swirl generating cylinder has multiple airflow holes 9 on its side wall, and multiple swirl blades 13 are arranged circumferentially inside the cylinder and above the burner. During combustion, the hot airflow drives the swirl generating cylinder to rotate through the swirl blades, forming a swirl, which accelerates airflow and ensures thorough mixing with the exhaust gas, thereby improving the completeness of exhaust gas combustion. Furthermore, when the flame is small, the impact force of the hot airflow on the swirl blades is small, and the swirl generating cylinder rotates slowly; conversely, when the flame is large, the swirl generating cylinder rotates quickly. Therefore, the combustion torch of this application can automatically adjust the swirl generating speed, effectively ensuring complete combustion of exhaust gas without the need for additional drive devices, thus saving energy and being adaptive.

[0022] As a further improvement to the above technical solution, the air inlet of the burner is connected to the exhaust gas delivery pipe 4 via a quick-release flange 5, and the two quick-release flanges are connected by a quick-release ball valve 6 to achieve quick disassembly; this facilitates quick and convenient cleaning of the burner.

[0023] As a further improvement to the above technical solution, a heat insulation layer 1 is provided on the inner side of the upper section of the torch tube 2 to prevent high-temperature radiation to the external environment.

[0024] As a further improvement to the above technical solution, an air inlet 3 is provided on the lower side wall of the torch tube. In this embodiment, multiple air inlets are provided circumferentially on the lower side wall of the torch tube; by arranging the air inlets, sufficient air circulation is ensured during the combustion process.

[0025] Unless otherwise stated, if any of the technical solutions disclosed in this invention specify a numerical range, then the disclosed numerical range is a preferred numerical range. Anyone skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this invention discloses only some numerical values ​​to illustrate the technical solutions of this invention. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this invention.

[0026] Furthermore, if the present invention discloses or relates to mutually fixedly connected components or structural parts, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral molding process).

[0027] Furthermore, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this invention include states or shapes that are similar to, close to, or approximate with those relationships. Any component provided by this invention can be assembled from multiple individual components or can be a single component manufactured using a one-piece molding process.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
