Description

Technical Field

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

[0002] At present, most of the high-temperature dust removal applications in China use the method of cooling first and then dust removal. According to the different requirements of production equipment and process temperature, different cooling processes are adopted to meet different dust removal process flows. For example, in the dust removal of the coal gasification section in large-scale coal chemical industry, whether it is pressurized or normal pressure gasification in the existing dust removal process, a long process method of high-energy-consuming Venturi water cooling and cyclone air cooling is mostly used.

[0003] However, this method has extremely high water consumption and generates a large amount of washing wastewater. Taking the 3052 project in coal chemical industry as an example, calculated based on 40,000³ of raw coal gas per hour in an atmospheric gasifier, when washing 40,000 cubic meters of raw coal gas down to normal temperature, 1500 tons of foul-smelling black water for washing will be generated immediately. To treat a large amount of black water, a huge sewage treatment plant needs to be built at a huge cost to treat the washing black water. Since there has been no new dust removal technology substitute, the traditional process with high energy consumption and high pollution has continued to be used until now.

[0004] To solve this problem, a high-temperature dust removal filter cartridge has emerged. This is a device specifically 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 > 1500°, which is suitable for purifying dust with high filtration temperature.

[0005] However, if the length of the filter cartridge is relatively long, due to insufficient jet pressure, the ash cleaning at the lower part of the filter cartridge will be incomplete, resulting in a relatively thick dust layer accumulating in the lower part of the filter cartridge, leading to a decrease in the filtration efficiency of the entire filter cartridge. At this time, the filter element needs to be replaced. However, due to the unique porous structure of sponge alloy metal being easily damaged, when being impacted by external force or over-compressed during the installation and replacement process, the porous structure of sponge alloy metal will be damaged, thus affecting the filtration performance.

Detailed implementation manners

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0062] Such as Figures 1 to 9As shown in the figure, this embodiment proposes a high-temperature resistant dust removal filter cartridge, which includes a stainless steel wire mesh 1, and also includes a lower mounting ring 2, an upper mounting ring 3, a sponge alloy metal 4, an upper end cap 5, a lower end cap 6, a positioning component, a disassembly and assembly component, and an assembly component. The lower mounting ring 2 is detachably mounted on the lower part of the stainless steel wire mesh 1, the upper mounting ring 3 is detachably mounted on the upper part of the stainless steel wire mesh 1, the sponge alloy metal 4 is detachably mounted inside the stainless steel wire mesh 1, and 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. The upper end cap 5 is detachably mounted on the upper mounting ring 3, and the lower end cap 6 is detachably mounted on the lower mounting ring 2. Positioning components are installed inside both the upper end cap 5 and the lower end cap 6. The positioning component includes a positioning frame 7, a positioning hole 8, and a positioning part. Two positioning frames 7 are symmetrically and fixedly mounted on the inner top wall of the upper end cap 5, and two positioning frames 7 are symmetrically and fixedly mounted on the inner bottom wall of the lower end cap 6. The two positioning frames 7 on the upper end cap 5 correspond to the two positioning frames 7 on the lower end cap 6 one by one. Positioning holes 8 are formed inside all four positioning frames 7, and positioning parts are installed inside all four positioning holes 8.

[0063] Specifically, when installing the high-temperature resistant dust removal filter cartridge in this application, 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 cylindrical mesh tube rolled from the stainless steel wire mesh 1 respectively. 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, roll the sponge alloy metal 4 into a cylindrical filter element. The diameter of the outer rotating surface of the filter element should be smaller than the diameter inside the cylindrical mesh tube rolled from the stainless steel wire mesh 1, and finally make the sponge alloy metal 4 contact the inner side of the stainless steel wire mesh 1. Then, the sponge alloy metal 4 can be fixed. At this time, first install the lower end cap 6 on the lower mounting ring 2, and then install the corresponding disassembly and assembly component on the two positioning frames 7 on the lower end cap 6. Through the setting of the positioning part, the position of the disassembly and assembly component on the lower end cap 6 can be fixed. At this time, adjust the disassembly and assembly component, and through the disassembly and assembly component, abut against the sponge alloy metal 4, so as to fix the relative position between the sponge alloy metal 4 and the stainless steel wire mesh 1. Then install the upper end cap 5 on the upper mounting ring 3. During the installation process, the position of the disassembly and assembly component can be appropriately adjusted to facilitate the docking of the upper part of the disassembly and assembly component with the positioning frame 7 on the inner top wall of the upper end cap 5. Then, through the setting of the assembly component, fix the relative position between the upper end cap 5 and the lower end cap 6, and the installed high-temperature resistant dust removal filter cartridge can be installed on the dust removal equipment and start working.

[0064] It should be noted that between the upper end cover 5 and the upper mounting ring 3, and between the lower end cover 6 and the lower mounting ring 2 in this application, a threaded connection method can be adopted for connection, or other connection methods can also be used. During the installation process, when the disassembly and assembly component is installed on the lower end cover 6, the shape and position of the disassembly and assembly component 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 and assembly component, and then the position of the disassembly and assembly component can be restored and it can be installed.

[0065] It should be added that due to the three-dimensional network structure of the sponge alloy metal 4, using the inherent characteristics of the sponge alloy metal 4, its temperature resistance melting point > 1500°, the normal operating temperature of the filter cartridge can be not less than 600°C, the tangential air inlet structure, the filtration pore diameter < 5μm, the filtration permeability of the filter cartridge > 90%. Due to the high smoothness of the pore alloy structure, the inert gas blowing does not block the filter cartridge, which improves the service life. It is suitable for filtering high-temperature, flammable and explosive, toxic and harmful, acid and alkali corrosion-resistant, and highly viscous dust. And the filtration air velocity can be adjusted according to the production process requirements and environmental emission standards. The filtration air velocity can be from 1 - 5 m / s or higher. For the same filtration area, the higher the filtration air velocity, the smaller the floor area of the equipment.

[0066] The outer dimensions of the filter cartridge of this application can be adjusted and designed according to user needs. The filter cartridge diameter ranges from 350 to 600 mm, and the length can be stacked and extended.

[0067] This application is more suitable for the dust removal of the high-temperature furnace in non-ferrous metallurgy and the direct discharge and valuable dust recovery. This dust removal can be directly dry-recovered, and the process flow is simpler.

[0068] As described above, such as Figure 6 、 Figure 7 shown, the positioning part includes a positioning block 9 and a connecting spring 10. Two positioning blocks 9 are symmetrically and slidably installed in each of 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.

[0069] Specifically, when installing the mounting frame 11, the mounting frames 11 at the bottoms 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 frame 7, relative sliding occurs between them. 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 by the connecting spring 10 and enters the positioning groove 12 on the mounting frame 11, and then the mounting frame 11 can be fixed.

[0070] Such as Figure 4 、 Figure 8 and Figure 9As shown in the figure, a disassembly and assembly component is installed on the positioning component for disassembling and assembling the sponge alloy metal 4. Among them, the positioning component is used to fix the disassembly and assembly component. The disassembly and assembly component includes an installation frame 11, a positioning groove 12, an arc-shaped connecting plate 13, an adaptive adjustment part, and an installation part. Installation frames 11 are slidably arranged on the four positioning frames 7. Positioning grooves 12 are symmetrically arranged inside the four installation frames 11. The positioning grooves 12 are adapted to the positioning blocks 9. Arc-shaped connecting plates 13 are fixedly installed between the two installation frames 11 near the inner top wall of the upper end cover 5 and the two installation frames 11 near the inner bottom wall of the lower end cover 6. Adaptive adjustment parts are installed on the four installation frames 11 for adjusting the pressure between the installation and the sponge alloy metal 4 during installation. Installation parts are 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.

[0071] Specifically, the two arc-shaped connecting plates 13 are inserted onto the two positioning frames 7 on the lower end cover 6 through the installation frames 11 at the bottom. Through the cooperation of the positioning block 9 and the connecting spring 10, the positioning block 9 is matched with the positioning groove 12, and the relative position between the installation frame 11 and the positioning frame 7 can be fixed. Then, through the settings of the adaptive adjustment part and the installation part, the installation part abuts against the sponge alloy metal 4, thereby fixing the sponge alloy metal 4.

[0072] As described above, such as Figure 9 As shown in the figure, the adaptive adjustment part includes a sliding frame 14, a butting frame 15, an arc-shaped strip 16, and a positioning screw 17. Sliding frames 14 are slidably installed on the four installation frames 11. Butting frames 15 are fixedly installed at the ends of the four sliding frames 14 away from the stainless steel wire mesh 1. Arc-shaped strips 16 are fixedly installed on the four butting frames 15. Positioning screws 17 are detachably installed on the four butting frames 15.

[0073] Specifically, after the two arc-shaped connecting plates 13 are installed, the installation of the upper end cover 5 can be started. During the installation of the upper end cover 5, since the upper end cover 5 will rotate, at this time, a certain pressure is applied to the arc-shaped connecting plate 13 first, so that the arc-shaped connecting plate 13 undergoes a certain degree of elastic deformation, and the installation frame 11 above the arc-shaped connecting plate 13 moves downward by 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 installation frame 11 above the arc-shaped connecting plate 13 corresponds to the positioning frame 7 on the upper end cover 5.

[0074] As described above, such as Figure 8 、 Figure 9As shown, the installation part includes an arc-shaped mounting plate 18 and a sliding groove 19. 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, arc-shaped mounting plates 18 are symmetrically and slidably installed. Among them, the end of the positioning screw 17 abuts against the arc-shaped mounting plate 18. Sliding grooves 19 are opened at both ends of the four arc-shaped mounting plates 18, and the sliding grooves 19 are slidably matched with the arc-shaped strips 16. It also includes stabilizing pieces 20 and diversion 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 pieces 20 are fixedly installed at equal angles in a circumferential shape. A plurality of diversion grooves 21 are equidistantly opened at both ends of each stabilizing piece 20.

[0075] Specifically, after the arc-shaped connecting plate 13 is installed, adjust the position between the arc-shaped mounting plate 18 and the abutting frame 15. At this time, the sliding groove 19 and the arc-shaped strip 16 slide relative to each other, so as to adjust the position between the arc-shaped mounting plate 18 and the abutting frame 15. After adjustment, at this time, both the arc-shaped mounting plate 18 and the arc-shaped strip 16 abut against the sponge alloy metal 4. Then, through the setting of the positioning screw 17, the relative position between the arc-shaped mounting plate 18 and the arc-shaped strip 16 is fixed, making the installation more reliable, thereby fixing the sponge alloy metal 4. Adjust the position of the stabilizing piece 20, and then the upper end cover 5 can be installed.

[0076] It should be added that the main function of the stabilizing piece 20 is to ensure the stability of the upper and lower arc-shaped mounting plates 18. The stabilizing piece 20 is made of a material that is heat-resistant and has a certain elasticity. When installing the upper end cover 5, when pressure is applied to the arc-shaped connecting plate 13 to make it deform, pressure also needs to be applied to the arc-shaped mounting plate 18, so that the stabilizing piece 20 undergoes elastic deformation at the same time, thereby ensuring the stability of the installation of the upper end cover 5. A plurality of arc-shaped diversion grooves 21 are also provided on the elastic piece.

[0077] Regarding the cleaning of the sponge alloy metal 4, as Figure 8 shown, the position of the end of the arc-shaped groove far from the sponge alloy metal 4 is higher than the position of the end close to the sponge alloy metal 4. When cleaning the sponge alloy metal 4 by means of reverse air blowing, if the tubular structure rolled by the sponge alloy metal 4 is too long, the cleaning may not be thorough. However, through the setting of the arc-shaped groove, the cleaning quality of the sponge alloy metal 4 can be improved.

[0078] As Figure 5As shown in the figure, an assembly component is installed between the upper end cover 5 and the lower end cover 6 to fix the relative positions of the upper end cover 5 and the lower end cover 6. The assembly component includes assembly holes 22 and long bolts 23. On both the upper end cover 5 and the lower end cover 6, a plurality of assembly holes 22 are circumferentially formed. The plurality of assembly holes 22 on the upper end cover 5 correspond one by one to the corresponding assembly holes 22 on the lower end cover 6. Between the plurality of assembly holes 22 on the upper end cover 5 and the corresponding assembly holes 22 on the lower end cover 6, long bolts 23 can be detachably installed.

[0079] Specifically, after the upper end cover 5 is installed, on the premise that the installation positions of the upper installation ring 3 and the lower installation ring 2 correspond, after the upper end cover 5 is installed at this time, the plurality of assembly holes 22 on the upper end cover 5 correspond one by one to the plurality of assembly holes 22 on the lower end cover 6. At this time, through the setting of the long bolts 23, through the cooperation of the long bolts 23 and the assembly holes 22, the relative position between the upper end cover and the lower end cover 6 can be fixed.

[0080] The working principle or usage process of this application is as follows:

[0081] 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 installation ring 3 and the lower installation ring 2 at both ends of the mesh cylinder rolled by the stainless steel wire mesh 1 respectively. The installation positions of the upper installation ring 3 and the lower installation ring 2 must correspond to facilitate the installation of the filter element rolled by the sponge alloy metal 4. At this time, roll the filter element made of the sponge alloy metal 4 into a cylindrical shape. The diameter of the outer circumferential surface of the filter element is smaller than the diameter of the inner part of the mesh cylinder rolled by the stainless steel wire mesh 1. Finally, make the sponge alloy metal 4 contact the inner side of the stainless steel wire mesh 1, and then the sponge alloy metal 4 can be fixed.

[0082] Install the lower end cover 6 on the lower installation ring 2. When installing the mounting frame 11, align the mounting frames 11 at the bottoms of the two arc-shaped connecting plates 13 with the two positioning frames 7 on the lower end cover 6 respectively. When the mounting frame 11 is docked with the positioning frame 7, relative sliding occurs between them. 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, at this time, the positioning block 9 is ejected from the positioning hole 8 under the action of the connecting spring 10 and enters the positioning groove 12 on the mounting frame 11, and the relative position between the mounting frame 11 and the positioning frame 7 can be fixed.

[0083] After installing the arc-shaped connecting plate 13, adjust the position between the arc-shaped mounting plate 18 and the abutting frame 15. At this time, relative sliding occurs between the sliding groove 19 and the arc-shaped strip 16, thereby adjusting the position between the arc-shaped mounting plate 18 and the abutting frame 15. After adjustment, both the arc-shaped mounting plate 18 and the arc-shaped strip 16 are in contact with the sponge alloy metal 4. Then, through the setting of the positioning screw 17, the relative position between the arc-shaped mounting plate 18 and the arc-shaped strip 16 is fixed, making the installation more reliable. Adjust the position of the stabilizing piece 20 to thus fix the sponge alloy metal 4.

[0084] 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, first apply a certain pressure to the arc-shaped connecting plate 13 at this time, causing a certain degree of elastic deformation of the arc-shaped connecting plate 13. At the same time, it is also necessary to apply pressure to the arc-shaped mounting plate 18, causing the stabilizing piece 20 to undergo elastic deformation simultaneously, so that the mounting frame 11 on the upper part of the arc-shaped connecting plate 13 moves downward by a certain distance, and then the upper end cover 5 can be installed. Then restore the position of the arc-shaped connecting plate 13, 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, through the setting of the long bolt 23, through the cooperation of the long bolt 23 and the assembly hole 22, the relative position between the upper end cover and the lower end cover 6 can be fixed.

[0085] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
