Description

Technical Field

[0001] This utility model relates to the field of regeneration equipment technology, specifically a low-temperature denitrification catalyst regeneration device. Background Technology

[0002] The low-temperature denitrification catalyst regeneration device is mainly used to restore the activity of deactivated catalysts, enabling them to continue to efficiently remove nitrogen oxides. This device employs advanced technological principles for regeneration. Through high-temperature heating, deposits such as carbon and sulfur on the catalyst surface are decomposed or volatilized, restoring the catalyst's pore structure and active sites. The heating temperature is generally kept within a suitable range to ensure regeneration effectiveness. Simultaneously, a specific gas, such as oxygen, is introduced during the regeneration process to promote chemical reactions and enhance the regeneration process. The device has a robust temperature control and atmosphere conditioning system, precisely maintaining the required temperature, humidity, and gas composition for regeneration. It features high regeneration efficiency and strong stability. The regeneration efficiency can reach a high level, bringing the catalyst performance close to its initial state, ensuring efficient low-temperature denitrification. Furthermore, the device operates stably and reliably, allowing for long-term continuous operation, reducing the risk of production interruptions due to frequent maintenance, lowering operating costs, and contributing to nitrogen oxide emission reduction in industrial production. This invention relates to a low-temperature denitrification catalyst regeneration device disclosed in utility model patent publication number CN221934832U.

[0003] However, low-temperature denitrification catalyst regeneration devices present certain environmental challenges in practical use. Because the low-temperature denitrification catalyst generates toxic gases during the heating process, direct release of these gases into the surrounding environment without proper treatment will cause serious air pollution. The toxic gases produced are complex in composition and may contain harmful chemicals; even small emissions can adversely affect the surrounding air quality, harm the habitat of plants and animals, and impact the health of residents. Therefore, effectively treating these toxic gases and preventing air pollution has become a crucial issue that urgently needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature denitrification catalyst regeneration device, which solves the problem that when the low-temperature denitrification catalyst is heated, it will produce toxic gas, and direct emission of this gas will easily pollute the surrounding air.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature denitrification catalyst regeneration device, comprising a regeneration device body, an outlet pipe fixedly disposed at the upper end of the regeneration device body, a connecting pipe inserted into the outer side of the outlet pipe, a fixing block fixedly connected to the upper end of the regeneration device body, a limiting sleeve rotatably connected to the outer side of the fixing block, a limiting frame fixedly connected to the outer side of the connecting pipe, a filter box fixedly connected to the end of the connecting pipe away from the outlet pipe, and a filtering mechanism disposed on the filter box.

[0008] Preferably, the limiting frame is in contact with the limiting sleeve, and the limiting frame is slidably connected to the main body of the regeneration device. Through the design of the limiting frame, the connecting pipe can be positioned.

The sliding rod is slidably connected to the filter box. A limiting ring is fixedly connected inside the filter box, and the limiting ring is in contact with the pull plate and slidably connected to the sliding rod. A spring is provided on the outside of the sliding rod. Through the design of the filtration mechanism, toxic gases generated by the main body of the regeneration device can be filtered.

[0010] Preferably, the clamp is slidably connected to the filter box and the filter element. The design of the clamp allows for easy disassembly and replacement of the filter element.

[0011] Preferably, one end of the spring contacts the limiting ring, and the other end of the spring contacts the sliding rod. Through the design of the spring, the locking rod can be driven to limit the filter element.

[0021] 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.

[0022] Please see Figure 1-5 A low-temperature denitrification catalyst regeneration device includes a regeneration device body 1. An outlet pipe 2 is fixedly installed at the upper end of the regeneration device body 1. A connecting pipe 21 is inserted into the outer side of the outlet pipe 2. A fixing block 22 is fixedly connected to the upper end of the regeneration device body 1. A limiting sleeve 23 is rotatably connected to the outer side of the fixing block 22. The limiting sleeve 23 contacts the regeneration device body 1. The limiting sleeve 23 and the connecting pipe 21 are connected by threads. The design of the limiting sleeve 23 ensures that the connection between the connecting pipe 21 and the outlet pipe 2 remains stable, limiting the connection. The sleeve 23 is internally fixedly connected to a protrusion 24, which is slidably connected to the fixing block 22. The protrusion 24 is designed to limit the sleeve 23. The outer side of the connecting pipe 21 is fixedly connected to a limiting frame 25, which contacts the limiting sleeve 23 and is slidably connected to the main body 1 of the regeneration device. The limiting frame 25 is designed to position the connecting pipe 21. The end of the connecting pipe 21 away from the outlet pipe 2 is fixedly connected to a filter box 3, which is equipped with a filter mechanism 4.

[0023] Please see Figure 2-5The filtration mechanism 4 includes a filter element 41. The filter element 41 is slidably connected inside the filter box 3. Both ends of the filter box 3 are in contact with pull plates 42. A locking rod 43 is fixedly connected to the side of the pull plate 42 near the filter box 3. The locking rod 43 is slidably connected to the filter box 3 and to the filter element 41. The design of the locking rod 43 makes it easy to disassemble and replace the filter element 41. A sliding rod 44 is fixedly connected to the side of the pull plate 42 near the filter box 3.

[0024] Please see Figure 2-5 The slide rod 44 is slidably connected to the filter box 3. The filter box 3 is fixedly connected to the limit ring 45. The limit ring 45 is in contact with the pull plate 42. The limit ring 45 is slidably connected to the slide rod 44. A spring 46 is provided on the outside of the slide rod 44. One end of the spring 46 is in contact with the limit ring 45 and the other end of the spring 46 is in contact with the slide rod 44. Through the design of the spring 46, the clamping rod 43 can be driven to limit the filter element 41. Through the design of the filtration mechanism 4, the toxic gas generated by the main body 1 of the regeneration device can be filtered.

[0025] The specific implementation process of this utility model is as follows: In use, by inserting the connecting pipe 21 into the air outlet pipe 2, the connecting pipe 21 drives the limiting frame 25 to be inserted into the main body 1 of the regeneration device. Then, the limiting sleeve 23 is rotated to make the limiting sleeve 23 and the connecting pipe 21 undergo threaded movement, thereby making the connection between the connecting pipe 21 and the air outlet pipe 2 stable and avoiding leakage at the connection between the connecting pipe 21 and the air outlet pipe 2.

[0026] When the main body 1 of the regeneration device generates toxic gas, the toxic gas enters the connecting pipe 21 through the gas outlet pipe 2, so that the connecting pipe 21 enters the filter box 3, and is discharged after being filtered by the filter element 41.

[0027] By moving the pull plate 42 away from the filter box 3, the pull plate 42 drives the slide rod 44 to slide within the limiting ring 45, causing the slide rod 44 to compress the spring 46, and causing the pull plate 42 to drive the locking rod 43 to slide out of the filter element 41, the limiting of the filter element 41 can be released, and the filter element 41 can be disassembled and replaced.

[0028] 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.
