Description

Technical Field

[0001] This utility model belongs to the technical field of industrial flue gas purification equipment, and in particular relates to a high-temperature resistant flue gas dust collector. Background Technology

[0002] Industries such as metallurgy, power, chemical industry, and waste incineration produce high-temperature flue gas, which contains high-hardness and corrosive dust. In order to ensure production efficiency and equipment safety, and reduce harm to the environment and human health, dust removal is required for high-temperature flue gas in industrial production.

[0003] High-temperature flue gas dust collectors use sintered metal filter media. This type of filter media has irreplaceable advantages in extreme working conditions (such as ultra-high temperature, high dust hardness, and strong corrosion) due to its excellent high temperature resistance, wear resistance, and corrosion resistance. However, during the use of high-temperature flue gas dust collectors, the blowing of high-temperature gas causes the sintered metal filter media to shake and rub against each other. Long-term and frequent friction can easily cause holes or tears to form on the surface of the sintered metal filter media. Furthermore, the interlayer bonding of the sintered metal filter media depends on the high-temperature sintering force. When shaking, shear stress is generated between the layers, which can easily lead to cracking at the sintering joints, separation between layers, and an increase in the pore size, affecting the filtration effect. Therefore, a high-temperature flue gas dust collector that can limit the shaking of the filter media is needed. Utility Model Content

[0004] The purpose of this invention is to stabilize the filter cartridge by setting a stabilizing component with a fixed through hole that is compatible with the filter cartridge. When the high-temperature flue gas dust collector is working, the bottom of the filter cartridge is inserted into the fixed through hole, thereby stabilizing the filter cartridge and preventing it from shaking. This solves the problem in the background art where the blowing of high-temperature gas causes friction between the filter cartridges, damaging the filter cartridges and affecting the filtration effect.

[0005] The specific technical solution of this utility model is as follows: A high-temperature resistant flue gas dust collector includes a housing, an internal filter chamber with a top opening, a cover on the top of the housing, an inlet pipe communicating with the filter chamber at the bottom of the housing, an outlet pipe communicating with the filter chamber at the top of the housing, and an installation mechanism inside the filter chamber. The installation mechanism includes an installation component, several connecting rods on the lower surface of the installation component, the bottom ends of the connecting rods being connected to a stabilizing component, several mounting through holes in the installation component, filter cartridges installed in the mounting through holes, and a fixing through hole adapted to the filter cartridges located at the orthogonal projection of the mounting through holes on the upper surface of the stabilizing component.

[0006] Furthermore, the outer surfaces of the stabilizer and the mounting components are respectively attached to the inner wall of the filter chamber, and the inner wall of the filter chamber is provided with limiting components that are used in conjunction with the stabilizer.

[0007] Furthermore, the stabilizing component is equipped with ventilation slots.

[0008] Furthermore, the inner facade of the filter chamber is provided with several linear sliding grooves, the outer facade of the mounting component is provided with several sliders 1 that are matched with the linear sliding grooves, the outer facade of the stabilizing component is provided with several sliders 2 that are matched with the linear sliding grooves, and the lower surface of the cover is provided with several positioning components that are adapted to the linear sliding grooves. When the cover is placed on the housing, the lower end face of the positioning component is in contact with the upper surface of the slider 1.

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

[0010] Furthermore, the mounting through hole is a threaded hole, and the upper part of the filter cartridge is provided with an external thread that matches the threaded hole.

[0011] Furthermore, the top of the filter cartridge is provided with an annular barrier, the outer diameter of which is larger than the inner diameter of the mounting through hole, and an operating handle is provided on the upper surface of the barrier.

[0012] Furthermore, the cover is connected to a backflush pipe, which is connected to the filter chamber, and a blind plate is fitted at the top of the backflush pipe.

[0013] Furthermore, the outer facade of the shell is provided with several reinforcing ribs, and a support plate is fixedly provided around the outer facade of the shell. Several legs are provided at the bottom of the support plate, and a base is provided at the bottom of the legs. The base is provided with fixing holes.

[0014] Furthermore, the bottom of the shell is designed as an inverted cone shape, with a drain pipe located at the bottom of the inverted cone. The drain pipe is connected to the filter chamber. A manhole pipe is located on the side of the inverted cone and is connected to the filter chamber.

[0015] Compared with the prior art, the present invention has the following beneficial effects: Before using the high-temperature resistant flue gas dust collector, install the filter cartridge on the mounting bracket and insert the bottom of the filter cartridge into the corresponding fixing through hole. When the high-temperature resistant flue gas dust collector is in use, high-temperature flue gas is blown into the filter chamber from the inlet pipe. Due to the stabilizing effect of the stabilizer on the filter cartridge, the flowing high-temperature flue gas will not cause the filter cartridge to shake, avoiding damage caused by mutual friction between the filter cartridges. It also avoids the problem of the metal sintered filter screen on the filter cartridge becoming larger due to shaking, which would affect the filtration effect. This reduces equipment wear, extends the service life of the filter cartridge, and improves the filtration effect of the filter cartridge. Attached Figure Description

[0018] 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 2 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.

[0019] See Figures 1 to 6This embodiment discloses a high-temperature resistant flue gas dust collector, including a housing 1. In this embodiment, the housing 1 has a rectangular cross-section. The housing 1 has a filter chamber 11 with a top opening inside. A cover 2 is mounted on the top of the housing 1, and the cover 2 is assembled with the housing 1 using bolt and nut assemblies. An inlet pipe 12 communicating with the filter chamber 11 is located at the lower part of the housing 1. High-temperature flue gas enters the filter chamber 11 through the inlet pipe 12. An outlet pipe 13 communicating with the filter chamber 11 is located at the upper part of the housing 1. The filtered gas is discharged from the filter chamber 11 through the outlet pipe 13. Further optimization involves installing regulating valves on the inlet pipe 12 and the outlet pipe 13 to control the gas flow rate. An installation mechanism is located inside the filter chamber 11, between the inlet pipe 12 and the outlet pipe 13. The installation mechanism includes an installation component 31, and several connecting rods 32 are provided on the lower surface of the installation component 31. In this embodiment, the several connecting rods 32... At the four corners of the mounting component 31, several connecting rods 32 are connected to the bottom of a stabilizing component 33. The mounting component 31 has several mounting through holes 311, and a filter cartridge 4 is installed in the mounting through holes 311. In this embodiment, the filter cartridge 4 is made of metal sintered filter screen, which has the characteristics of corrosion resistance and high temperature resistance, and is suitable for the working environment of high temperature flue gas dust collector. A fixing through hole 331 adapted to the filter cartridge 4 is provided at the orthogonal projection of the mounting through hole 311 on the upper surface of the stabilizing component 33. Before using the high temperature flue gas dust collector, the filter cartridge 4 is installed on the mounting component 31, and the bottom of the filter cartridge 4 is inserted into the corresponding fixing through hole 331. Then, the mounting mechanism is installed into the housing 1, and the cover 2 is closed. Due to the stabilizing effect of the stabilizing component 33 on the filter cartridge 4, the flowing high temperature flue gas will not cause the filter cartridge 4 to shake, avoiding damage caused by mutual friction between the filter cartridges 4, and also avoiding the metal sintered filter screen of the filter cartridge 4 from shaking, which would cause the filter pores to become larger and affect the filtration effect.

[0020] The outer surfaces of the stabilizer 33 and the mounting component 31 are respectively attached to the inner wall of the filter chamber 11 to increase the airtightness. The inner wall of the filter chamber 11 is provided with a limiting component 14 for use with the stabilizer 33. When the mounting mechanism is placed into the filter chamber 11, the lower surface of the stabilizer 33 is attached to the upper surface of the limiting component 14.

[0021] The stabilizer 33 is provided with a ventilation slot 332. High-temperature flue gas enters the space between the mounting part 31 and the stabilizer 33 through the ventilation slot 332 and is filtered through the filter cartridge 4, which increases the filtration area and improves the filtration effect.

[0022] The filter chamber 11 has several linear grooves 15 vertically arranged on its inner surface. In this embodiment, the linear grooves 15 are evenly distributed on the four inner surfaces of the filter chamber 11. The outer periphery of the mounting component 31 has several sliders 312 that are matched with the linear grooves 15. The outer periphery of the stabilizing component 33 has several sliders 333 that are matched with the linear grooves 15. The mounting mechanism is slidably connected to the filter chamber 11 through the sliding cooperation of sliders 312, sliders 333 and linear grooves 15. The lower surface of the cover 2 has several positioning components 21 that are adapted to the linear grooves 15. When the cover 2 is placed on the housing 1, the lower end face of the positioning component 21 is in contact with the upper surface of slider 312. The mounting mechanism is stabilized in the filter chamber 11 by the positioning component 21.

[0023] The upper surface of the mounting component 31 is provided with several threaded rods 34, and the threaded rods 34 are equipped with lifting eye nuts 35 to facilitate the hoisting operation of the mounting mechanism.

[0024] The mounting through hole 311 is a threaded hole, and the upper part of the filter cylinder 4 is provided with an external thread that matches the threaded hole. The filter cylinder 4 achieves threaded connection with the mounting part 31 through the threaded engagement of the external thread and the threaded hole.

[0025] The filter cartridge 4 is provided with an annular barrier 41 at the top. The outer diameter of the barrier 41 is larger than the inner diameter of the mounting through hole 311. The upper surface of the barrier 41 is provided with an operating handle 42. In this embodiment, the operating handle 42 is a lifting ring with both ends welded to the barrier 41, and two are provided opposite to each other on the upper surface of the barrier 41, so as to facilitate the screwing and lifting of the filter cartridge 4 by operating the handle 42.

[0026] The cover 2 is connected to a backflush pipe 22, which is connected to the filter chamber 11. When the filter cartridge 4 needs to be cleaned, the filter chamber 11 is bleed through the backflush pipe 22 to make the dust adhering to the surface of the filter cartridge 4 fall off. A blind plate 221 is installed at the top of the backflush pipe 22. When the high-temperature flue gas dust collector is working, the blind plate 221 is installed at the end of the backflush pipe 22 with fastening bolts to block the backflush pipe 22.

[0027] The outer surface of the shell 1 is provided with several reinforcing ribs 16. In this embodiment, the reinforcing ribs 16 are arranged in a crisscross pattern to improve the structural strength of the shell 1. A support plate 17 is fixedly provided around the outer surface of the shell 1. The support plate 17 is close to the lower part of the shell 1. Several support legs 5 are provided at the bottom of the support plate 17. The bottom of the support legs 5 is provided with a base 51. The base 51 is provided with a fixing hole 52. The high-temperature resistant flue gas dust collector is fixed to the ground by the cooperation of expansion screws with the fixing hole 52, thereby increasing the stability of the high-temperature resistant dust collector.

[0028] The bottom of the housing 1 is designed as an inverted cone shape, and a drain pipe 18 is provided at the bottom of the inverted cone shape. The drain pipe 18 is connected to the filter chamber 11, and dust particles are discharged from the filter chamber 11 through the drain pipe 18. A manhole pipe 19 is provided on the side of the inverted cone shape, and the manhole pipe 19 is connected to the filter chamber 11. When the machine is stopped for maintenance, maintenance workers can enter the filter chamber 11 through the manhole pipe 19 to perform maintenance and repair on the equipment. In this embodiment, both the manhole pipe 19 and the drain pipe 18 are equipped with sealing flanges. When the high-temperature flue gas dust collector is working, the manhole pipe 19 and the drain pipe 18 are sealed by the cooperation of the fastening bolts and nuts and the sealing flanges.

[0029] Working principle: Before using the high-temperature flue gas dust collector, the filter cartridge 4 is installed on the mounting part 31, and the bottom of the filter cartridge 4 is inserted into the corresponding fixing through hole 331. Then, the mounting mechanism is installed into the housing 1, and the cover 2 is closed. Through the cooperation of the positioning part 21 and the limiting part 14, the mounting mechanism is fixed in the filter chamber 11. When the high-temperature flue gas dust collector is in use, the high-temperature flue gas is blown into the filter chamber 11 from the inlet pipe 12. After being filtered by the filter cartridge 4, the filtered gas is discharged from the filter chamber 11 from the outlet pipe 13 at the top of the housing 1. The filtered particles fall into the bottom of the housing 1 and are discharged from the filter chamber 11 through the drain pipe 18. Due to the stabilizing effect of the stabilizer 33 on the filter cartridge 4, the flowing high-temperature flue gas will not cause the filter cartridge 4 to shake, avoiding damage caused by mutual friction between the filter cartridges 4. It also avoids the metal sintered filter screen of the filter cartridge 4 from shaking, which would cause the filter pores to become larger and affect the filtration effect.
