Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas catalytic combustion device that facilitates the replacement of gas components. Background Technology

[0002] Combustion-based oil and gas treatment processes involve using methods such as direct combustion, regenerative thermal oxidation combustion, or catalytic oxidation combustion to process hydrocarbon-containing gases generated during storage and transportation. The resulting carbon dioxide, water, and air are then directly discharged as purified gases.

[0003] Combustion-based oil and gas treatment processes primarily utilize catalytic combustion towers to treat waste gas. Existing combustion equipment is installed inside a combustion chamber, where it is exposed to corrosive oil and gas for extended periods and operates at high temperatures. This leads to oxidation and corrosion of internal components. Furthermore, routine maintenance requires the complete disassembly of the combustion chamber, making maintenance extremely inconvenient. While surface burners can effectively improve the treatment of harmful gases, their disassembly and maintenance are difficult. Removing surface burners necessitates the creation of large maintenance holes on the combustion chamber surface, directly impacting the overall strength of the combustion tower. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a waste gas catalytic combustion device that facilitates the replacement of gas components.

[0005] This utility model is achieved through the following technical solution:

The support rail is fixedly installed inside the combustion reaction chamber, the auxiliary strut is fixedly installed inside the combustion reaction chamber, the connecting block is fixedly installed outside the combustion reaction chamber, and the combustion mechanism is engaged inside the combustion reaction chamber. The combustion mechanism includes a cover plate, a guide socket, a support frame, a retaining ring, an air inlet pipe, a support pipe, a surface burner, and an auxiliary retaining strip. The guide socket is fixedly installed at both ends of the cover plate, the support frame is fixedly installed inside the guide socket, the retaining ring is fixedly installed at the top of the support frame, the air inlet pipe is engaged inside the retaining ring, the support pipe is installed at the top of the air inlet pipe, the surface burner is connected to the top of the support pipe, and the auxiliary retaining strip is fixedly installed inside the cover plate.

[0007] In a preferred embodiment of this utility model, the surface of the combustion reaction chamber is provided with mounting holes, and an auxiliary support rod is fixedly disposed in the middle of the mounting holes on the surface of the combustion reaction chamber.

[0008] The mounting holes on the surface of the combustion reaction chamber facilitate the installation of the surface burner and its auxiliary accessories, and also allow for the removal of internal components during maintenance.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0022] like Figure 1-4 The exhaust gas catalytic combustion device shown includes a combustion reaction chamber 1, a support rail 2, an auxiliary support rod 3, a connecting block 4, and a combustion mechanism 5. The support rail 2 is fixedly installed inside the combustion reaction chamber 1, the auxiliary support rod 3 is fixedly installed inside the combustion reaction chamber 1, the connecting block 4 is fixedly installed outside the combustion reaction chamber 1, and the combustion mechanism 5 is engaged inside the combustion reaction chamber 1. The combustion mechanism 5 includes a cover plate 51, a guide socket 52, a support frame 53, a retaining ring 54, an air inlet pipe 55, a support pipe 56, a surface burner 57, and an auxiliary retaining strip 58. The guide socket 52 is fixedly installed at both ends of the cover plate 51, the support frame 53 is fixedly installed inside the guide socket 52, the retaining ring 54 is fixedly installed at the top of the support frame 53, the air inlet pipe 55 is engaged inside the retaining ring 54, the support pipe 56 is installed at the top of the air inlet pipe 55, the surface burner 57 is connected to the top of the support pipe 56, and the auxiliary retaining strip 58 is fixedly installed inside the cover plate 51.

[0023] Specifically, the combustion reaction chamber 1 has mounting holes on its surface. The auxiliary support rod 3 is fixedly installed in the middle of the mounting holes on the surface of the combustion reaction chamber 1. The cover plate 51 is installed on the outside of the mounting holes on the surface of the combustion reaction chamber 1. The surface burner 57 is installed on both sides of the auxiliary support rod 3. The top and bottom of the auxiliary clip 58 are in contact with the top and bottom of the mounting holes. The bottom of the support frame 53 is in contact with the top of the support rail 2. A guide block is provided at the bottom of one end of the support frame 53. A guide groove is provided at the top of the support rail 2 to cooperate with it. The guide socket 52 is installed on the outside of the connecting block 4 and is fixed to one end of the connecting block 4 with screws.

[0024] In this embodiment, a gas connector is provided at the end of the intake pipe 55. After the gas is input, it enters the surface burner 57 through the support pipe 56. By increasing the flame area, the contact effect between the exhaust gas and the flame is ensured, thereby greatly improving the conversion efficiency of harmful gases in the exhaust gas, thus achieving the ideal exhaust gas treatment effect. The intake pipe 55 is connected to the support frame 53 through the retaining ring 54. The support frame 53 is fixed to the inside of the cover plate 51 and is clamped on the top of the support rail 2 to ensure that the surface burner 57 is stably and horizontally set in the combustion reaction chamber 1. After the cover plate 51 is installed in place, it is fixed by the fixing screw at the tail of the guide socket 52 and the threaded hole at the tail of the connecting block 4. At this time, the auxiliary retaining strip 58 on the inside of the cover plate 51 is clamped in the mounting hole on the surface of the combustion reaction chamber 1 to provide auxiliary support, thereby ensuring the support strength of the combustion reaction chamber 1.

[0025] Furthermore, when routine maintenance and internal parts replacement are required, loosen the fixing screws on the back of the guide socket 52 and pull the cover plate 51 outward. At this time, the guide socket 52 moves backward outside the connecting block 4, and the support frame 53 moves backward on the top of the support rail 2. The guide block at the bottom of the support frame 53 is locked in the guide groove at the top of the support rail 2, which effectively provides support and limit effect when pulled out. After being pulled out, the auxiliary clip 58 will no longer provide support. At this time, the auxiliary support rod 3 fixed in the combustion reaction chamber 1 ensures the support effect. The surface burner 57 has two semi-circular structures, which avoids interference with the auxiliary support rod 3 during installation and disassembly. Therefore, during routine maintenance and parts replacement, it is not necessary to disassemble the equipment on the top of the combustion reaction chamber 1, which can achieve quick replacement and facilitate routine maintenance work.

[0026] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
