Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for waste gas combustion, specifically a waste gas catalytic combustion processor. Background Technology

[0002] The development of catalytic combustion technology for waste gas originated from the need for efficient oxidation of combustible pollutants in industrial waste gas treatment. Its technological evolution revolves around the iteration of catalyst materials, optimization of reaction devices, and process adaptation. Early industrial waste gas treatment mainly relied on direct combustion, which required high temperatures and consumed a lot of energy and was prone to secondary pollution. In the 1940s, the application of precious metal catalysts (platinum and palladium) in tail gas treatment laid the foundation for catalytic combustion technology. From the 1960s to the 1980s, as VOCs emissions from industries such as chemical and coating became more prominent, catalytic combustion technology developed from single precious metal catalysis to a composite system of "carrier-active component-co-catalyst". Porous carriers such as honeycomb ceramics and cordierite gradually replaced particulate carriers due to their advantages in mass transfer efficiency. At the same time, the development of non-precious metal catalysts (manganese, cobalt, and copper oxides) reduced costs.

[0003] Existing patent document CN218820443U discloses a waste gas catalytic combustion processor, including a processor assembly and a placement assembly. The processor assembly includes a processor housing, an inlet pipe vertically fixed to the lower side of the middle of the processor housing side wall, an outlet pipe vertically fixed to the middle of the upper end of the processor housing, and a through groove formed in the side wall of the processor housing. The placement assembly includes a placement plate whose outer wall is attached to the inner wall of the through groove, a first slot formed in the upper part of the placement plate, a second slot formed in the lower part of the placement plate and connected to the first slot, and a filter screen whose outer wall is attached to the inner wall of the first slot. A handle is fixed to the middle of the opposite outer wall of the placement plate. The filter screen is provided with two layers. A catalyst is located in the middle of the filter screen. In this type of waste gas catalytic combustion processor, the filter screen and the internal catalyst are placed on a placement plate. The placement plate can be pulled out from the through groove of the processor housing using a handle, making it easy for the operator to remove and replace the internal catalyst. Although the above application has many beneficial effects, it still has the following shortcomings: In actual operation, the filter screen continuously intercepts particulate matter such as dust and paint mist in the waste gas, and an impurity accumulation layer is easily formed on its surface. It needs to be removed regularly for cleaning. Cleaning and coating maintenance operations both require a certain amount of time and must be completed when the system is shut down, which has a corresponding impact on the continuity of the overall treatment process. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas catalytic combustion processor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas catalytic combustion processor, comprising a pipe, a replacement mechanism provided on the pipe, the replacement mechanism comprising a main filter screen, a secondary filter screen, multiple threaded grooves and multiple overlapping rollers, symmetrically arranged connecting blocks fixedly connected to both the main filter screen and the secondary filter screen, each connecting block being threadedly connected with a positioning bolt, symmetrically arranged support rods fixedly connected to both the main filter screen and the secondary filter screen, adjacent support rods being jointly fixedly connected with a connecting belt, and a catalyst coating being applied to both the main filter screen and the secondary filter screen.

[0006] Preferably, the main filter screen is slidably connected inside the pipe, and the secondary filter screen is slidably connected to the bottom wall of the pipe.

[0007] Preferably, both the outer wall of the main filter screen and the outer wall of the secondary filter screen are fixedly connected with sealing gaskets, and the overlapping rollers are symmetrically rotated and connected to the front and back walls of the pipe.

[0008] Preferably, the connecting belt is hooked to the overlapping roller at the corresponding overlapping roller position.

[0009] Preferably, the threaded grooves are all formed on the bottom wall of the pipe at the positions corresponding to the positioning bolts, and the two positioning bolts of the connecting block on the main filter screen are threadedly connected to the corresponding threaded grooves.

[0010] Preferably, both the main filter and the auxiliary filter are fixedly connected to a pull handle at their bottom ends.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The filter replacement mechanism adopts a parallel configuration of main and auxiliary filters, which can realize uninterrupted switching of filters. When the main filter needs to be removed for cleaning and maintenance due to impurity accumulation, it can be quickly switched through the replacement mechanism, and the exhaust gas passage can be switched to the backup auxiliary filter immediately. The auxiliary filter then takes over the catalytic treatment work, ensuring the continuous operation of the exhaust gas catalytic combustion process, effectively guaranteeing the stable operation time and treatment efficiency of the entire exhaust gas treatment system. The disassembly and installation steps of the filter are combined into disassembly and installation at the same time, which indirectly improves the catalytic efficiency of the exhaust gas.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] A catalytic combustion processor for exhaust gas includes a pipe 1 with a replacement mechanism 2. The replacement mechanism 2 includes a main filter 21, a secondary filter 22, multiple threaded grooves 23, and multiple overlapping rollers 24. Both the main filter 21 and the secondary filter 22 are fixedly connected to symmetrically arranged connecting blocks 25. Each connecting block 25 is threadedly connected to a positioning bolt 26. Both the main filter 21 and the secondary filter 22 are fixedly connected to symmetrically arranged support rods 27. Adjacent support rods 27 are all fixedly connected to a connecting belt 28. Both the main filter 21 and the secondary filter 22 are coated with a catalyst coating 29.

[0020] The main filter screen 21 is slidably connected inside the pipe 1, and the secondary filter screen 22 is slidably connected to the bottom wall of the pipe 1. Sealing gaskets are fixedly connected to the outer walls of both the main filter screen 21 and the secondary filter screen 22. Overlapping rollers 24 are symmetrically rotated and connected to the front and back walls of the pipe 1. The sealing gaskets prevent leakage at the connection points between the main filter screen 21, the secondary filter screen 22, and the pipe 1. The connecting belt 28 is hooked onto the overlapping rollers 24 at positions corresponding to the overlapping rollers 24. The overlapping rollers 24 can be the connecting belt 2... 8 provides support. The threaded grooves 23 are all opened on the bottom wall of the pipe 1 at the positions of the corresponding positioning bolts 26. The two positioning bolts 26 of the connecting block 25 on the main filter screen 21 are threadedly connected to the corresponding threaded grooves 23. The connection between the positioning bolts 26 and the threaded grooves 23 can be used to position the main filter screen 21 and the auxiliary filter screen 22 through the connecting block 25. The bottom ends of the main filter screen 21 and the auxiliary filter screen 22 are fixedly connected to the pull handles, which facilitate the movement of the main filter screen 21 and the auxiliary filter screen 22.

[0021] In use, pipe 1 can be connected to the intake pipe of the combustion chamber. When exhaust gas enters the combustion chamber through pipe 1, it will be filtered by the main filter 21. At the same time, the catalyst coating 29 on the main filter 21 will react with the exhaust gas, making the exhaust gas burn more completely in the subsequent combustion chamber. When the main filter 21 needs to be cleaned, rotate the two positioning bolts 26. The positioning bolts 26 will first separate from the threaded grooves 23 on the bottom wall of pipe 1. At this time, the positioning of the main filter 21 is released. The operator can pull the main filter 21 downwards. The downward movement of the main filter 21 will drive the two support rods 27 downwards. The downward movement of the support rods 27 will pull the connecting belt 28, causing the connecting belt to... When one end of the belt 28 moves downward, the other end of the belt 28 moves upward. The overlapping roller 24 provides a fulcrum for the movement of the belt 28. The upward movement of the belt 28 will drive the corresponding support rod 27 to move upward. At this time, the two support rods 27 will jointly drive the secondary filter screen 22 to move upward and fully insert it into the inside of the pipe 1. Then, the two positioning bolts 26 on the secondary filter screen 22 can be connected to the corresponding threaded grooves 23. After that, the staff can immediately clean the main filter screen 21 and apply the catalyst coating 29 on the main filter screen 21. The disassembly and installation steps of the filter screen are combined into disassembly and installation at the same time, which can reduce the time required for cleaning the device and make the operation more convenient.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
