[0002] In industrial production sectors such as metallurgy, power, chemical industry, waste incineration, and new energy material preparation, dust removal and purification of high-temperature gases are crucial for achieving environmental compliance, resource recovery, and safe equipment operation. Direct emission of dust particles (such as fly ash, metal oxides, and catalyst carriers) contained in high-temperature gases can not only cause air pollution and harm human health, but may also lead to wear and tear on downstream equipment, catalyst poisoning, or loss of process materials.

[0003] Traditional high-temperature gas dust collectors use filter bags to filter dust particles. In high-temperature environments, filter bags are prone to oxidation and aging, resulting in a short lifespan. Furthermore, once the filter bags become clogged, the machine must be shut down for cleaning. Frequent shutdowns for cleaning and filter bag replacement increase equipment maintenance costs and reduce enterprise production efficiency. Utility Model Content

A flange three is provided at the outer end of the manhole pipe. A sealing plate three is assembled on the flange three through a bolt and nut assembly three.

[0008] Furthermore, the inner facade of the filter chamber is provided with several linear grooves vertically, and the outer facade of the mounting plate is provided with sliders that are compatible with the linear grooves. The mounting plate achieves a sliding connection with the housing through the sliding cooperation between the sliders and the linear grooves. The inner facade of the filter chamber is provided with a blocking component around the perimeter. The upper surface of the blocking component is coplanar with the upper surface of the bottom of the linear groove. The lower surface of the top cover is provided with a sliding strip that is compatible with the linear groove. When the top cover is placed on the housing, the lower end face of the sliding strip is in contact with the upper surface of the mounting plate.

[0009] Furthermore, the upper surface of the mounting plate is provided with several threaded rods, and the threaded rods are equipped with eye nuts.

[0010] Furthermore, a threaded hole is provided at the bottom of the mounting through hole, and an external thread is provided at the top of the filter cylinder to match the threaded hole.

[0019] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] See Figures 1 to 6This embodiment discloses a high-temperature gas dust collector, including a housing 1. A filter chamber 11 is provided inside the housing 1, with an opening at the top. A top cover 2 is provided on the top of the housing 1. The housing 1 has an inlet pipe 12 and an outlet pipe 13. The inlet pipe 12 is located at the lower part of the housing 1 and communicates with the filter chamber 11. The outlet pipe 13 is located at the upper part of the housing 1 and communicates with the filter chamber 11. A mounting plate 3 is connected inside the filter chamber 11. The outer surface of the mounting plate 3 is fitted to the inner surface of the filter chamber 11 to increase the filtration effect. The mounting plate 3 is located between the inlet pipe 12 and the outlet pipe 13. The mounting plate 3 has several mounting through holes 31, and filter cartridges 32 are fitted into the mounting through holes 31. The filter cartridges 32 are made of metal. Further optimization is possible by... The filter cylinder 32 is made of nickel-based alloy and has a porous structure formed by precision sintering, making it suitable for extreme high temperature and high pressure environments. The top cover 2 is connected to an air blowing pipe 21, which is connected to the filter chamber 11. The top of the air blowing pipe 21 is equipped with a sealing plate 211. The bottom of the shell 1 is connected to a drain pipe 14, which is connected to the filter chamber 11. The bottom of the drain pipe 14 is equipped with a sealing plate 2. When the high temperature gas dust collector is used for normal filtration, the sealing plate 211 is installed on the air blowing pipe 21 and the sealing plate 2 is installed on the drain pipe 14 to prevent gas leakage. When the filter cylinder 32 is blocked, the sealing plate 211 is removed and air is blown into the filter chamber 11 through the air blowing pipe 21, which can blow off the dust particles on the outer surface of the filter cylinder 32 and solve the blockage problem.

[0021] The top of the air blowing pipe 21 is provided with flange 1, and the sealing plate 211 is assembled with flange 1 by bolt and nut assembly 1. The bottom of the sewage pipe 14 is provided with flange 2, and the sealing plate 2 is assembled with flange 2 by bolt and nut assembly 2. It can be further optimized that a gasket 1 is placed between sealing plate 211 and flange 1, and a gasket 2 is placed between sealing plate 2 and flange 2 to increase the sealing performance and prevent gas containing dust particles from leaking.

[0022] The bottom of the housing 1 is designed in an inverted cone shape, which facilitates the accumulation of dust particles at the bottom of the housing 1. The drain pipe 14 is located at the lowest point of the inverted cone bottom, which can clean the dust particles and prevent the accumulation of dust particles inside the filter chamber 11. A manhole pipe 15 is provided on the side facade located at the bottom of the inverted cone. The manhole pipe 15 is connected to the filter chamber 11. If dust blocks the drain pipe 14, the operator can clean the dust particles and unclog the drain pipe 14 through the manhole pipe 15. A flange 3 is provided at the outer end of the manhole pipe 15. The flange 3 is equipped with a sealing plate 3 151 by bolt and nut assembly 3. Further optimization is possible by providing a gasket 3 between the flange 3 and the sealing plate 3 151 to increase the sealing performance and prevent the leakage of gas containing dust particles.

[0023] The filter chamber 11 has several vertical linear grooves 16 on its inner surface. The mounting plate 3 has a slider 33 on its outer surface that matches the linear grooves 16. The mounting plate 3 is slidably connected to the housing 1 through the sliding engagement of the slider 33 and the linear grooves 16. The filter chamber 11 has a blocking member 17 on its inner surface around its perimeter. The upper surface of the blocking member 17 is coplanar with the upper surface of the bottom of the linear grooves 16. The lower surface of the top cover 2 has a sliding strip 22 that matches the linear grooves 16. When the top cover 2 is placed on the housing 1, the lower end face of the sliding strip 22 is in contact with the upper surface of the mounting plate 3. The mounting plate 3 is fixed in place by the cooperation of the sliding strip 22 and the blocking member 17, preventing the mounting plate 3 from shaking during the filtration process and affecting the filtration effect.

[0024] The upper surface of the mounting plate 3 is provided with several threaded rods 34, and the threaded rods 34 are equipped with lifting eye nuts 35. When it is necessary to inspect the filter cartridge 32 and the inside of the housing 1, the cooperation between the threaded rods 34 and the lifting eye nuts 35 makes it convenient for operators to lift the mounting plate 3.

[0025] The lower part of the mounting through hole 31 is provided with a threaded hole 311. The inner diameter of the threaded hole 311 is larger than the inner diameter of the mounting through hole 31. The top of the filter cartridge 32 is provided with an external thread that matches the threaded hole 311. The filter cartridge 32 is installed under the mounting plate 3 through the threaded engagement of the external thread and the threaded hole 311. The threaded connection increases the firmness of the connection and facilitates disassembly and assembly. It can be further optimized that the inner diameter of the filter cartridge 32 is the same as the inner diameter of the mounting through hole 31, which reduces gas flow resistance and improves filtration efficiency.

[0026] The shell 1 has a rectangular cross-section. The rectangular structure distributes stress more evenly under high temperature conditions, provides strong frame support stability, and is less prone to deformation due to thermal expansion and contraction. In addition, the rectangular design saves installation space. The top of the shell 1 is provided with a square flange 18, and the top cover 2 is provided with a square flange 23. The square flange 18 and the square flange 23 are compatible. The top cover 2 is assembled on the shell 1 through the square flange 18, the square flange 23 and the bolt and nut assembly 4. It can be further optimized by providing a gasket 4 between the square flange 18 and the square flange 23 to increase the sealing performance and prevent the leakage of gas containing dust particles.

[0027] The outer facade of the shell 1 is provided with several reinforcing ribs 19, which are arranged in a crisscross pattern to enhance the overall structural strength of the shell 1. The outer facade of the shell 1 is fixed with stiffening plates 5 around the perimeter, and several support legs 51 are provided at the bottom of the stiffening plates 5. By increasing the connection area between the support legs 51 and the shell 1, the stiffening plates 5 disperse local stress and reduce the risk of cracking of the shell 1.

[0028] The top of the top cover 2 is designed as an outwardly convex arc-shaped top, and the lower surface of the outwardly convex arc-shaped top is an inwardly concave arc-shaped top. The inwardly concave arc-shaped top can evenly distribute the impact pressure load of the gas on the top cover 2 along the arc-shaped surface, reducing the pressure on the top cover 2. The upper surface of the outwardly convex arc-shaped top is provided with a handle 24 to facilitate the removal and movement of the top cover 2.

[0029] The outer ends of the air inlet pipe 12 and the air outlet pipe 13 are respectively connected to valves 4. When gas is introduced into the filter chamber 11 through the air inlet pipe 12 for purging, the valves 4 are closed to prevent dust particles from entering the air inlet pipe 12 and the air outlet pipe 13.

[0030] Working principle: During use, high-temperature gas containing dust particles enters the filter chamber 11 through the inlet pipe 12 at the bottom of the housing 1. The dust particles are filtered outside the filter cartridge 32 and fall to the bottom of the housing 1. The filtered gas enters the filter cartridge 32 and is discharged from the filter chamber 11 through the outlet pipe 13 at the top of the housing 1. The filter cartridge 32 is made of metal, with high mechanical strength, impact resistance, wear resistance, and high temperature resistance, which improves the service life of the filter cartridge 32. When the filter cartridge 32 becomes clogged, the valve 4 at the outer end of the inlet pipe 12 and the outlet pipe 13 is closed. Gas is introduced into the filter chamber 11 through the blowing pipe 21 to purge the filter cartridge 32. This back-blowing removes the dust particles adsorbed on the outer wall of the filter cartridge 32 and discharges the dust particles from the housing 1 through the drain pipe 14. This reduces the number of times the high-temperature gas dust collector needs to be disassembled and the filter cartridge 32 needs to be cleaned, thus reducing equipment maintenance costs and improving enterprise production efficiency.
