Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a multi-tube dust collector. Background Technology

[0002] Currently, the high-temperature flue gas generated during pellet production contains a large amount of dust, which is often separated and purified using multi-tube dust collectors. Multi-tube dust collectors generally consist of several parallel-arranged guide ducts and corresponding cyclone separation units, achieving particle and gas separation through inertial centrifugal force.

[0003] In actual production, it was found that the spacing between the ducts of multi-tube dust collectors is usually only about 20cm. Some of the dust carried by the flue gas is separated inside the dust collector, while some accumulates at the top of the cyclone inlet. Due to the small spacing between the ducts, maintenance personnel cannot enter the ductwork for manual cleaning, resulting in severe dust accumulation at the cyclone inlet, and even blockage. This significantly reduces ventilation and dust removal efficiency, seriously affecting the orderly organization and operation of pellet production.

[0004] Therefore, there is an urgent need for a multi-tube dust collector to solve the above problems. Utility Model Content

[0040] This embodiment provides a multi-tube dust collector, such as Figures 1-5 As shown, the multi-tube dust collector includes a shell and several air guide ducts 100. Several air guide ducts 100 are arrayed within the shell, each including a first air guide duct 110 and a second air guide duct 120. Multiple first air guide ducts 110 are arranged at intervals along a predetermined path within the shell, while second air guide ducts 120 are arranged in the space outside the predetermined path. Each first air guide duct 110 is formed by splicing multiple pipe segments arranged sequentially along its axial direction, with adjacent pipe segments connected by a detachable connection structure. When needed, a maintenance passage 10 can be quickly formed by disassembling the middle pipe segment, allowing maintenance personnel to easily access the upper area of ​​the cyclone inlet for dust removal. This structure effectively expands the working space inside the multi-tube dust collector, improves dust removal efficiency and effect, ensures the ventilation volume of the multi-tube dust collector, and significantly improves the continuity and reliability of the pellet production process.

[0041] Optionally, the preset path shape can be T-shaped, L-shaped, C-shaped, or U-shaped. The arrangement of the first air guide duct 110 can be flexibly adjusted according to the needs of the maintenance passage 10 inside the casing of the multi-tube dust collector, further optimizing the space utilization inside the casing, ensuring dust removal efficiency, and thus improving the maintainability and applicability of the equipment.

[0042] like Figure 1 As shown, in this embodiment, the preset path is preferably T-shaped, and one end of the preset path is close to the workshop passage 10, which makes it easier for maintenance personnel to enter the maintenance passage 10 and improves the convenience of dust removal.

[0043] Optionally, such as Figure 3 As shown, the first air duct 110 includes a first pipe section 111, a second pipe section 112, and a third pipe section 113 connected in sequence. The first pipe section 111 is detachably connected to the second pipe section 112 through a first flange structure, and the second pipe section 112 is detachably connected to the third pipe section 113 through a second flange structure. The second pipe section 112 of the first air duct 110 can be disassembled separately as needed during maintenance or cleaning, thereby expanding the working space and improving the dust removal efficiency.

[0044] Optionally, such as Figure 3 As shown, the second pipe section 112 is located in the lower part of the first air guide duct 110. The length of the second pipe section 112 accounts for 30%-40% of the total length of the first air guide duct 110, specifically 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, and 40%. For example, the length of a common air guide duct 100 is approximately 2m, meaning both the first air guide duct 110 and the second air guide duct 120 are 2m. Preferably, the length of the second pipe section 112 accounts for 35% of the length of the first air guide duct 110, meaning the length of the second air guide duct 120 is 0.7m. This design, while ensuring the structural strength of the air guide duct 100, creates a working space that is easy for maintenance personnel to access, thereby significantly improving maintenance efficiency, shortening downtime, and ensuring the stability and dust removal effect of the multi-tube dust collector during long-term operation.

[0045] Optionally, the first flange structure includes a first flange, a second flange 210, and a first fastening assembly. The first flange is disposed at one end of the first pipe section 111, and the first flange includes a plurality of first through holes; as shown Figure 4 and Figure 5 As shown, the second flange 210 is located at the first end of the second pipe section 112. The second flange 210 includes multiple second through holes 211, each corresponding to a first through hole. The first fastening assembly passes through and fastens the corresponding first and second through holes 211 sequentially. This structure not only ensures the sealing and stability of the first air guide duct 110 during operation, but also facilitates maintenance and cleaning of accumulated dust, improves maintenance efficiency, and to some extent shortens equipment downtime, enhancing the operational flexibility and maintainability of the multi-tube dust collector.

[0046] In this embodiment, the fastening bolts of the first fastening component can improve the reliability of the connection between the first pipe section 111 and the second pipe section 112, and also facilitate disassembly and repeated installation, making the operation simple and the maintenance efficiency high.

[0047] Optionally, a first sealing gasket is provided between the first flange and the second flange 210. This can further improve the sealing performance at the connection between the first pipe section 111 and the second pipe section 112, effectively prevent flue gas leakage, and ensure the stable operation of the duct 100 in a high-temperature, high-speed airflow environment.

[0048] Optionally, the second flange structure includes a third flange 220, a fourth flange, and a second fastening assembly. The third flange 220 is located at the second end of the second pipe section 112 and includes multiple third through holes 221. The fourth flange is located at one end of the third pipe section 113 and includes multiple fourth through holes, each corresponding to one of the third through holes 221. The second fastening assembly passes through and fastens the corresponding third through holes 221 and fourth through holes sequentially. This structure not only ensures the sealing and stability of the second air guide duct 120 during operation but also facilitates maintenance and cleaning of accumulated dust, improves maintenance efficiency, and to some extent shortens equipment downtime, enhancing the operational flexibility and maintainability of the multi-tube dust collector.

[0049] In this embodiment, the second fastening component fastening bolt can improve the stability and reliability of the connection between the second pipe section 112 and the third pipe section 113, and is also easy to disassemble and reinstall, making the operation simple and the maintenance efficiency high.

[0050] Optionally, a second sealing gasket is provided between the third flange 220 and the fourth flange. This can further improve the sealing performance at the connection between the second pipe section 112 and the third pipe section 113, effectively prevent flue gas leakage, and ensure the stable operation of the duct 100 in a high-temperature, high-speed airflow environment.

[0051] Optionally, the first air duct 110 and / or the second air duct 120 are made of alloy steel or stainless steel, which can significantly improve the high temperature resistance, corrosion resistance and wear resistance of the first air duct 110 and the second air duct 120, and extend the service life of the equipment.

[0052] Optionally, the number of second air guide ducts 120 accounts for 15%-30% of the total number of first air guide ducts 110 and second air guide ducts 120. This allows for efficient use of the internal space of the casing, providing more operational space for maintenance and cleaning of accumulated dust, while ensuring efficient flue gas flow and dust removal. Optionally, the number of first air guide ducts 110 can account for 15%, 20%, 25%, 30% of the total number of first air guide ducts 110 and second air guide ducts 120, etc., and the number of first air guide ducts 110 can be flexibly set according to actual dust removal needs.
