Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature filter cartridges, and in particular to a high-temperature resistant dust removal filter cartridge. Background Art

[0002] At present, most of the high-temperature dust removal methods used in China are to cool down first and then remove dust. According to the different requirements of production equipment and process temperature, different cooling processes are used to meet different dust removal process flows. For example, in large-scale coal chemical industry, the coal gasification section dust removal and existing dust removal processes, whether pressurized or normal pressure gasification, mostly adopt the energy-intensive and long process of Venturi water cooling and cyclone air cooling.

[0003] However, this method consumes a lot of water and produces a lot of washing wastewater. Taking the 3052 project of coal chemical industry as an example, the atmospheric pressure gasification furnace produces 40,000 cubic meters of raw gas per hour. Washing 40,000 cubic meters of raw gas to room temperature immediately produces 1,500 tons of smelly black water. In order to treat a large amount of black water, huge investments are needed to build a huge sewage treatment plant to treat the washing black water. Since there has been no new dust removal technology alternative, the traditional process with high energy consumption and high pollution continues to be used to this day.

[0004] In order to solve this problem, a high-temperature resistant dust filter cartridge has emerged. This is a device specially used for dust filtration in high-temperature environments. They can work stably under high-temperature conditions. The filter element is made of sponge alloy metal. Utilizing the inherent characteristics of sponge alloy metal, the temperature resistance melting point is greater than 1500°, which is suitable for filtering dust purification with high filtration temperatures.

[0005] However, if the length of the filter cartridge is too long, the lower area of ​​the filter cartridge will not be cleaned thoroughly due to insufficient blowing pressure, resulting in a thicker dust layer accumulated in the lower area of ​​the filter cartridge, causing the filtration efficiency of the entire filter cartridge to decrease. At this time, the filter element needs to be replaced. However, the unique porous structure of sponge alloy metal is easily damaged. During the installation and replacement process, when it is impacted by external force or excessive compression, the porous structure of the sponge alloy metal will be damaged, thereby affecting the filtration performance.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 9 As shown, this embodiment proposes a high temperature resistant dust removal filter cartridge, including a stainless steel wire mesh 1, a lower mounting ring 2, an upper mounting ring 3, a sponge alloy metal 4, an upper end cover 5, a lower end cover 6, a positioning component, a disassembly component and an assembly component. The lower mounting ring 2 can be detachably mounted on the lower part of the stainless steel wire mesh 1, the upper mounting ring 3 can be detachably mounted on the upper part of the stainless steel wire mesh 1, the sponge alloy metal 4 can be detachably mounted inside the stainless steel wire mesh 1, the upper and lower ends of the sponge alloy metal 4 are respectively abutted against the lower mounting ring 2 and the upper mounting ring 3, and the upper end cover 5 It can be detachably mounted on the upper mounting ring 3, and the lower end cover 6 can be detachably mounted on the lower mounting ring 2. Positioning components are installed inside the upper end cover 5 and the lower end cover 6. The positioning components include a positioning frame 7, a positioning hole 8 and a positioning part. Two positioning frames 7 are symmetrically and fixedly installed on the inner top wall of the upper end cover 5, and two positioning frames 7 are symmetrically and fixedly installed on the inner bottom wall of the lower end cover 6. The two positioning frames 7 on the upper end cover 5 correspond to the two positioning frames 7 on the lower end cover 6 one by one. Positioning holes 8 are opened inside the four positioning frames 7, and positioning parts are installed inside the four positioning holes 8.

[0023] Specifically, when installing the high-temperature resistant dust filter cartridge, the present application first rolls the stainless steel wire mesh 1 into a cylindrical shape and fixes its shape, and then respectively installs the upper mounting ring 3 and the lower mounting ring 2 at both ends of the mesh cylinder rolled from the stainless steel wire mesh 1, and the installation positions of the upper mounting ring 3 and the lower mounting ring 2 must correspond to facilitate the installation of the filter element rolled from the sponge alloy metal 4. At this time, the sponge alloy metal 4 is rolled into a cylindrical filter element, and the diameter of the rotating surface outside the filter element is smaller than the diameter inside the mesh cylinder rolled from the stainless steel wire mesh 1, so that the sponge alloy metal 4 is finally in contact with the inner side of the stainless steel wire mesh 1, and then the sponge alloy metal 4 can be fixed. At this time, first install the lower end cover 6 on the lower mounting ring 2, and then Finally, the corresponding disassembly and assembly components are installed on the two positioning frames 7 on the lower end cover 6. The position of the disassembly and assembly components on the lower end cover 6 can be fixed by the setting of the positioning part. At this time, the disassembly and assembly components are adjusted, and the sponge alloy metal 4 is pressed against the disassembly and assembly components to fix the relative position of the sponge alloy metal 4 and the stainless steel wire mesh 1. Then the upper end cover 5 is installed on the upper mounting ring 3. During the installation process, the position of the disassembly and assembly components can be appropriately adjusted to facilitate the docking of the upper part of the disassembly and assembly components with the positioning frames 7 on the inner top wall of the upper end cover 5. Then, the relative position between the upper end cover 5 and the lower end cover 6 is fixed by the setting of the assembly components, and the installed high-temperature resistant dust filter cartridge can be installed on the dust removal equipment, and work can be started.

[0024] It should be noted that the upper end cover 5 and the upper mounting ring 3, and the lower end cover 6 and the lower mounting ring 2 in the present application can be connected by a threaded connection method, or other connection methods can be used. During the installation process, when the disassembly assembly is installed on the lower end cover 6, the shape and position of the disassembly assembly can be adjusted first to facilitate the installation of the upper end cover 5 on the upper mounting ring 3. After the upper end cover 5 is installed, the positioning frame 7 on the upper end cover 5 corresponds to the upper part of the disassembly assembly, so that the position of the disassembly assembly can be restored and it can be installed.

[0025] It should be added that due to the three-dimensional network structure of sponge alloy metal 4 and the inherent characteristics of sponge alloy metal 4, its temperature-resistant melting point is greater than 1500°, the normal operating temperature of the filter cartridge can be no less than 600°C, the tangential air intake structure, the filter aperture is less than 5μm, and the filter cartridge filtration permeability is greater than 90%. Due to the high smoothness of the aperture alloy structure, the inert gas injection does not block the filter cartridge, thereby increasing the service life. It is suitable for filtering high-temperature, flammable and explosive, toxic and harmful, acid- and alkali-resistant, and highly viscous dust purification. In addition, the filtration wind speed can be adjusted from 1 to 5 m / s or higher according to the production process requirements and environmental emission standards. The higher the filtration wind speed for the same filtration area, the smaller the equipment footprint.

[0026] The external dimensions of the filter cartridge of the present application can be adjusted and designed according to user needs. The diameter of the filter cartridge ranges from 350 to 600 mm, and the length can be stacked and extended.

[0027] This application is more suitable for non-ferrous metallurgical high-temperature furnaces and direct discharge of valuable dust recovery. The dust can be directly recovered in a dry manner, and the process flow is simpler.

[0028] The above, such as Figure 6 , Figure 7 As shown, the positioning part includes a positioning block 9 and a connecting spring 10 , two positioning blocks 9 are symmetrically and slidably installed in the four positioning holes 8 , and a connecting spring 10 is fixedly installed between the two positioning blocks 9 in the four positioning holes 8 .

[0029] Specifically, when installing the mounting frame 11, the mounting frames 11 at the bottom of the two arc-shaped connecting plates 13 are respectively aligned with the two positioning frames 7 on the lower end cover 6. When the mounting frame 11 is docked with the positioning frames 7, the two slide relative to each other. At this time, the positioning block 9 slides in the positioning hole 8, and the positioning block 9 enters the positioning hole 8. At this time, the connecting spring 10 is compressed. When the mounting frame 11 moves to a determined position, the positioning block 9 is pushed out of the positioning hole 8 under the action of the connecting spring 10 and enters the positioning groove 12 on the mounting frame 11, so that the mounting frame 11 can be fixed.

[0030] like Figure 4 , Figure 8 and Fig. 9 As shown, a disassembly assembly is installed on the positioning assembly for disassembling and assembling the sponge alloy metal 4, wherein the positioning assembly is used to fix the disassembly assembly, the disassembly assembly includes a mounting frame 11, a positioning groove 12, an arc-shaped connecting plate 13, an adaptive adjustment portion and a mounting portion, the four positioning frames 7 are all slidably provided with mounting frames 11, the four mounting frames 11 are symmetrically provided with positioning grooves 12, the positioning grooves 12 are adapted to the positioning blocks 9, an arc-shaped connecting plate 13 is fixedly installed between the two mounting frames 11 close to the inner top wall of the upper end cover 5 and the two mounting frames 11 close to the inner bottom wall of the lower end cover 6, the four mounting frames 11 are all installed with an adaptive adjustment portion for adjusting the pressure between the sponge alloy metal 4 during installation, and a mounting portion is installed between the two positioning frames 7 on the inner top wall of the upper end cover 5 and between the two positioning frames 7 on the inner bottom wall of the lower end cover 6.

[0031] Specifically, the two arc-shaped connecting plates 13 are inserted into the two positioning frames 7 on the lower end cover 6 through the mounting frame 11 at the bottom. The positioning block 9 cooperates with the connecting spring 10 to make the positioning block 9 cooperate with the positioning groove 12, so as to fix the relative position between the mounting frame 11 and the positioning frame 7. Then, through the setting of the adaptive adjustment part and the mounting part, the mounting part is made to abut against the sponge alloy metal 4, thereby fixing the sponge alloy metal 4.

[0032] The above, such as Fig. 9As shown, the adaptive adjustment part includes a sliding frame 14, an abutment frame 15, an arc strip 16 and a positioning screw 17. The sliding frames 14 are slidably installed on the four mounting frames 11, the abutment frames 15 are fixedly installed on the ends of the four sliding frames 14 away from the stainless steel wire mesh 1, the arc strip 16 is fixedly installed on the four abutment frames 15, and the positioning screws 17 are detachably installed on the four abutment frames 15.

[0033] Specifically, after installing the two arc-shaped connecting plates 13, you can start installing the upper end cover 5. During the installation of the upper end cover 5, since the upper end cover 5 will rotate, a certain pressure is first applied to the arc-shaped connecting plate 13 to make the arc-shaped connecting plate 13 elastically deform to a certain extent, so that the mounting frame 11 on the upper part of the arc-shaped connecting plate 13 moves downward a certain distance. At this time, the upper end cover 5 can be installed, and then the position of the arc-shaped connecting plate 13 is restored so that the mounting frame 11 on the upper part of the arc-shaped connecting plate 13 corresponds to the positioning frame 7 on the upper end cover 5.

[0034] The above, such as Figure 8 , Fig. 9 As shown, the mounting portion includes an arc-shaped mounting plate 18 and a sliding groove 19. The arc-shaped mounting plates 18 are symmetrically and slidably mounted between the two abutting frames 15 close to the upper end cover 5 and between the two abutting frames 15 close to the lower end cover 6, wherein the end of the positioning screw 17 abuts against the arc-shaped mounting plate 18, and sliding grooves 19 are provided at both ends of the four arc-shaped mounting plates 18. The sliding grooves 19 are slidably matched with the arc-shaped bars 16, and also include stabilizing plates 20 and guide grooves 21. Between the two arc-shaped mounting plates 18 close to the upper end cover 5 and between the two arc-shaped mounting plates 18 close to the lower end cover 6, a plurality of stabilizing plates 20 are fixedly mounted at equal angles in a circular shape, and a plurality of guide grooves 21 are provided at equal distances at both ends of each stabilizing plate 20.

[0035] Specifically, after the arc-shaped connecting plate 13 is installed, the position between the arc-shaped mounting plate 18 and the abutment frame 15 is adjusted. At this time, the sliding groove 19 and the arc-shaped bar 16 slide relative to each other, thereby adjusting the position between the arc-shaped mounting plate 18 and the abutment frame 15. After the adjustment, the arc-shaped mounting plate 18 and the arc-shaped bar 16 are both in abutment with the sponge alloy metal 4. Then, the relative position between the arc-shaped mounting plate 18 and the arc-shaped bar 16 is fixed by setting the positioning screws 17, so that the installation is more reliable. After fixing the sponge alloy metal 4 and adjusting the position of the stabilizing plate 20, the end cover 5 can be installed.

[0036] It should be added that the main function of the stabilizing sheet 20 is to ensure the stability of the upper and lower parts of the arc-shaped mounting plate 18. The stabilizing sheet 20 is made of a material that is resistant to high temperatures and has a certain elasticity. When installing the upper end cover 5, while applying pressure to the arc-shaped connecting plate 13 to deform it, it is also necessary to apply pressure to the arc-shaped mounting plate 18 so that the stabilizing sheet 20 is elastically deformed at the same time, thereby ensuring the stability of the installation of the upper end cover 5. A plurality of arc-shaped guide grooves 21 are also provided on the elastic sheet.

[0037] For cleaning the sponge alloy metal 4, supplementation is performed, such as Figure 8 As shown, the position of the arc groove away from one end of the sponge alloy metal 4 is higher than the position close to the other end of the sponge alloy metal 4. When the sponge alloy metal 4 is cleaned by reverse blowing, if the cylindrical structure of the sponge alloy metal 4 is too long, the cleaning may not be in place. By setting the arc groove, the cleaning quality of the sponge alloy metal 4 can be improved.

[0038] like Figure 5 As shown, an assembly component is installed between the upper end cover 5 and the lower end cover 6 for fixing the relative positions of the upper end cover 5 and the lower end cover 6. The assembly component includes an assembly hole 22 and a long bolt 23. A plurality of assembly holes 22 are circumferentially opened on the upper end cover 5 and the lower end cover 6. The plurality of assembly holes 22 on the upper end cover 5 correspond one to one with the pair of assembly holes 22 on the lower end cover 6. The long bolts 23 can be detachably installed between the plurality of assembly holes 22 on the upper end cover 5 and the pair of assembly holes 22 on the lower end cover 6.

[0039] Specifically, after the upper end cover 5 is installed, on the premise that the installation positions of the upper mounting ring 3 and the lower mounting ring 2 correspond to each other, at this time, after the upper end cover 5 is installed, the multiple assembly holes 22 on the upper end cover 5 correspond one by one with the multiple assembly holes 22 on the lower end cover 6. At this time, by setting the long bolts 23 and cooperating with the assembly holes 22, the relative position between the upper end stem and the lower end cover 6 can be fixed.

[0040] The working principle or usage process of this application is: When installing the high-temperature resistant dust filter cartridge, first roll the stainless steel wire mesh 1 into a cylindrical shape and fix its shape, then install the upper mounting ring 3 and the lower mounting ring 2 at both ends of the mesh cylinder rolled with the stainless steel wire mesh 1, and the installation positions of the upper mounting ring 3 and the lower mounting ring 2 must correspond to facilitate the installation of the filter element rolled with the sponge alloy metal 4. At this time, roll the sponge alloy metal 4 into a cylindrical filter element, and the diameter of the rotating surface outside the filter element must be smaller than the diameter inside the mesh cylinder rolled with the stainless steel wire mesh 1, so that the sponge alloy metal 4 is finally in contact with the inner side of the stainless steel wire mesh 1, and then the sponge alloy metal 4 can be fixed.

[0041] The lower end cover 6 is installed on the lower mounting ring 2. When installing the mounting frame 11, the mounting frames 11 at the bottom of the two arc-shaped connecting plates 13 are respectively aligned with the two positioning frames 7 on the lower end cover 6. When the mounting frame 11 is docked with the positioning frames 7, the two slide relative to each other. At this time, the positioning block 9 slides in the positioning hole 8, and the positioning block 9 enters the positioning hole 8. At this time, the connecting spring 10 is compressed. When the mounting frame 11 moves to a determined position, the positioning block 9 is pushed out of the positioning hole 8 under the action of the connecting spring 10 and enters the positioning groove 12 on the mounting frame 11, so that the relative position between the mounting frame 11 and the positioning frame 7 can be fixed.

[0042] After installing the arc connecting plate 13, adjust the position between the arc mounting plate 18 and the abutment frame 15. At this time, the sliding groove 19 and the arc strip 16 slide relative to each other, thereby adjusting the position between the arc mounting plate 18 and the abutment frame 15. After adjustment, the arc mounting plate 18 and the arc strip 16 are now in abutment with the sponge alloy metal 4. Then, by setting the positioning screws 17, fix the relative position between the arc mounting plate 18 and the arc strip 16, so that the installation is more reliable. Adjust the position of the stabilizing plate 20 to fix the sponge alloy metal 4.

[0043] Specifically, after installing the two arc-shaped connecting plates 13, the upper end cover 5 can be installed. During the installation of the upper end cover 5, since the upper end cover 5 will rotate, a certain pressure is first applied to the arc-shaped connecting plate 13 to make the arc-shaped connecting plate 13 elastically deform to a certain extent. At the same time, it is also necessary to apply pressure to the arc-shaped mounting plate 18 to make the stabilizing plate 20 elastically deform at the same time, so that the mounting frame 11 on the upper part of the arc-shaped connecting plate 13 moves downward a distance, and the upper end cover 5 can be installed. Then, the position of the arc-shaped connecting plate 13 is restored, so that the mounting frame 11 on the upper part of the arc-shaped connecting plate 13 corresponds to the positioning frame 7 on the upper end cover 5. At this time, the relative position between the upper end stem and the lower end cover 6 can be fixed by setting the long bolts 23 and cooperating with the assembly holes 22.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
