[0002] Gasoline hydrogen refueling exhaust treatment devices are primarily used to reduce harmful substances in vehicle emissions, especially nitrogen oxides, carbon oxides, and unburned hydrocarbons. This device incorporates hydrogen to promote more complete combustion, thereby reducing the pollutant content in exhaust gases.

[0003] Existing gasoline hydrogenation exhaust gas treatment devices have the following drawbacks during use:

[0004] The most common method is filtration, but most filter structures are disposable and cannot be used twice, especially when the filter structure needs to be replaced urgently. This means that when replacing the filter structure, a replacement filter structure must be found first, then the machine must be shut down, and then the filter structure can be installed. This results in a long downtime and makes it difficult to replace the filter quickly. Secondly, the filter structure is usually fixed with bolts, but bolts are prone to rust after long-term use, making disassembly very inconvenient. Therefore, a gasoline hydrogenation exhaust gas treatment device is needed. Utility Model Content

[0024] Example

[0025] The most common method is filtration, but most filter structures are disposable and cannot be used twice, especially when the filter structure needs to be replaced urgently. This means that when replacing the filter structure, a replacement filter structure must be found first, then the machine must be stopped, and then the filter structure can be installed. This results in a longer downtime and makes it difficult to replace the filter structure quickly. Secondly, the filter structure is usually fixed with bolts, but bolts are prone to rust after long-term use, making disassembly very inconvenient.

[0026] For this purpose, please refer to Figure 1-6This utility model provides a gasoline hydrogenation exhaust gas treatment device, including: an exhaust pipe 2 fixed at the exhaust port at the top of the gasoline hydrogenation reaction equipment 1, the exhaust pipe 2 having an inverted L-shaped structure, a connecting plate 21 fixedly connected to the outside of the exhaust pipe 2, a base 3 fixedly connected to the top of the gasoline hydrogenation reaction equipment 1 on one side of the connecting plate 21, a filter cylinder 31 movably overlapping the top arc surface of the base 3, a clamping member 4 installed at both ends of the filter cylinder 31, and the clamping member 4 is also connected to the end of the connecting plate 21 away from the middle of the top of the gasoline hydrogenation reaction equipment 1; a switchable filter element is installed on the filter cylinder 31, which allows the filter cylinder 31 to be used twice with the cooperation of the clamping member 4.

[0027] Further as Figure 1-6 As shown, it is worth noting that in order to enable the filter cartridge 31 to be used twice and reduce the downtime for replacing the filter structure, a switchable filter element is provided, including air inlets 32 at the center of both ends of the filter cartridge 31. A second discharge pipe 341 is fixed to the exhaust port at the left end of the filter cartridge 31 directly below the left air inlet 32, and a first discharge pipe 34 is fixed to the exhaust port at the right end of the filter cartridge 31 directly above the right air inlet 32. A sleeve hole 37 is provided at the center of the end of the connecting plate 21 facing the filter cartridge 31 directly below for fitting the first discharge pipe 34 and the second discharge pipe 341. An inclined plate 35 is fixed inside the filter cartridge 31, which divides the filter cartridge 31 into two filter chambers. Filter packing 36, which is activated carbon, is fixed in both filter chambers.

[0028] A sealing plug 33 is movably inserted into the air inlet 32 ​​at the right end of the filter cartridge 31 to prevent dust from entering the air inlet 32.

[0029] Further as Figure 1-6 As shown, it is worth noting that in order to enable the filter cartridge 31 to be quickly installed and fixed, a clamping component 4 is provided, including multiple inserts 41 arranged in a ring array fixed to one end of the filter cartridge 31. The vertical cross-section of each insert 41 is I-shaped. Each insert 41 has two symmetrically distributed first inclined surfaces 411 at the end away from the filter cartridge 31. A groove is provided on the side wall of the insert 41 facing the air inlet 32. A lifting spring 412 is fixed to the inner wall of the groove on the side away from the filter cartridge 31. The end of the lifting spring 412 near the filter cartridge 31 protrudes out of the groove in an arc shape. Multiple slots 42 arranged in a ring array are provided at the end of the connecting plate 21 away from the middle of the top of the gasoline hydrogenation reaction device 1. The shape of the slots 42 is adapted to the shape of the inserts 41. Two symmetrically distributed second inclined surfaces 43 are provided at the opening of the slots 42. The second inclined surfaces 43 cooperate with the first inclined surfaces 411.

[0030] When the insert block 41 is inserted into the corresponding slot 42, the arc-shaped protruding end of the spring 412 is squeezed into the groove by the inner wall of the slot 42, thereby achieving the purpose of quick locking.

[0031] In summary: When using this gasoline hydrogenation exhaust gas treatment device, if the filter cartridge 31 needs to be replaced urgently after one use, the left end clamping piece 4 of the filter cartridge 31 can be removed from the connecting plate 21. After that, the right end of the filter cartridge 31 is reversed, and the first discharge pipe 34 is inserted into its sleeve hole 37, so that the right end air inlet 32 ​​of the filter cartridge 31 is sleeved on the outside of the exhaust pipe 2. In this way, the filter packing 36 in the two filter chambers separated by the partition can be replaced, reducing the downtime for replacement. In addition, the use of the insertion block 41 in conjunction with the lifting spring 412, and the combination of the first inclined surface 411 and the second inclined surface 43, makes it faster and more convenient to insert the insertion block 41 into the slot 42. The clamping force of the lifting spring 412 makes the filter cartridge 31 installed on the connecting plate 21 more stable.
