Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas treatment, and in particular relates to an integrated coordinated purification process for sulfur, dust and nitrate using ceramic fiber tubes. Background Art

[0002] The integrated synergistic purification process of sulfur, dust and nitrate in ceramic fiber tube is a denitrification and dust removal treatment equipment widely used in glass, waste incineration, coking, chemical and other industries. When the equipment treats the waste gas, the dusty sulfur and nitrate gas is sprayed with lime powder at the front flue, and enters the flue gas fluidization mixing tower after preliminary mixing through the static mixer, and undergoes a desulfurization reaction in the mixing tower. Then, the diluted ammonia is sprayed through the flue after the tower through the ammonia spray grid, and enters the ceramic fiber filter cartridge after the flow is equalized through the guide plate. The dust with larger particle size settles under the action of gravity, and the dust with smaller particle size is deposited on the surface of the ceramic fiber filter cartridge, and secondary desulfurization is carried out on the dust cake layer on the surface of the ceramic fiber filter cartridge. The dust-free sulfur gas passes through the surface of the ceramic fiber filter cartridge and then contacts the catalyst layer on the inner wall of the ceramic fiber filter cartridge to react. The nitrogen oxides are removed once and then discharged through the induced draft fan. When the dust is deposited on the surface of the ceramic fiber filter cartridge to a certain value, the compressed air pulses the filter cartridge for dust cleaning.

[0003] When pulse cleaning is performed on the surface of the ceramic fiber filter cartridge, since the outer side of the existing ceramic fiber filter cartridge lacks a protective device, the dust cleaned during the pulse cleaning operation will spread to the adjacent ceramic fiber filter cartridge surface, thereby affecting the cleaning efficiency and cleaning effect of the ceramic fiber filter cartridge.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] The present invention provides Figures 1 to 8 The illustrated method is a process for the integrated coordinated purification of sulfur, dust and nitrate by ceramic fiber tubes, which is applied to a coordinated purification device, wherein the coordinated purification device comprises a treatment tank 1, wherein a dust partition plate 2 is horizontally arranged inside the treatment tank 1, wherein a plurality of rows of jacks are provided on the top of the dust partition plate 2, and each row of jacks has a plurality of rows, wherein ceramic fiber tubes 3 are inserted into the jacks, and an air intake assembly 4 is provided on the top of the plurality of rows of ceramic fiber tubes 3, wherein an arc-surface enclosure 5 coaxial with the ceramic fiber tubes 3 is provided on the periphery of the ceramic fiber tubes 3 located at the bottom of the dust partition plate 2, and the top and bottom ends of the arc-surface enclosure 5 are fixedly connected with A first fixed ring 6 is provided, and the first fixed ring 6 at the top is rotatably connected to the bottom of the dust separation plate 2. A coaxial curved movable plate 7 is provided on the inner side of the curved surface enclosure plate 5. The top and bottom ends of the curved surface movable plate 7 are fixedly connected to a second fixed ring 8. The two second fixed rings 8 are rotatably installed on the inner side of the curved surface enclosure plate 5. A fixed rod 9 is fixedly connected to the inner side of the second fixed ring 8 at the bottom. A rotating shaft 10 is vertically fixedly connected to the bottom center of the fixed rod 9. The same fixed plate 11 is horizontally provided at the bottom of multiple fixed rods 9 in the same row. Both ends of the fixed plate 11 are connected to the inner side of the treatment tank 1. The wall is fixedly connected, and multiple rotating shafts 10 located in the same row are vertically penetrated and plugged into the fixed plate 11 facing the bottom. The bottom of the fixed plate 11 is provided with a driving assembly 12 for driving the rotating shaft 10 to rotate. A one-way sleeve 13 is sleeved on the rotating shaft 10, and the idling direction of the one-way sleeve 13 is opposite to the positive rotation direction of the rotating shaft 10. A plurality of L-shaped connecting rods 14 are fixedly connected between the one-way sleeve 13 and the first fixed ring 6 at the bottom. The top of the processing tank 1 is connected to an exhaust pipe 15, the side wall of the processing tank 1 is connected to an air intake pipe 16, the bottom of the processing tank 1 is connected to an ash discharge pipe 17, and the exhaust pipe 18 is connected to the exhaust pipe 19. An induced draft fan 18 is installed on the ash pipe 17. The diameter of the treatment tank 1 near the bottom gradually decreases from top to bottom, and the inner wall of the bottom end of the treatment tank 1 is smooth. The arc length of the curved movable plate 7 is the same as the arc length of the curved enclosing plate 5, and the arc lengths of the curved movable plate 7 and the curved enclosing plate 5 are both greater than half of the circumference of their circumferences. The top edge of the ceramic fiber tube 3 protrudes outward, and the width of the protruding part matches the width of the support ring 21. The bottom end of the ceramic fiber tube 3 is higher than the bottom of the curved movable plate 7. There is a gap between the curved movable plate 7 and the ceramic fiber tube 3, and there is also a gap between the two adjacent curved enclosing plates 5. The driving assembly 12 includes a driving shaft 121, which is horizontally arranged at the bottom of the fixed plate 11, and one end of the driving shaft 121 is drivingly connected to a driving motor 122, and the driving shaft 121 is rotatably sleeved with fixed blocks near both ends, and the fixed blocks are fixedly connected to the bottom of the fixed plate 11, and a plurality of first bevel gears 123 are sleeved on the driving shaft 121, and the plurality of first bevel gears 123 are respectively opposite to the plurality of rotating shafts 10 on the fixed plate 11, and a second bevel gear 124 is fixedly sleeved on the bottom end of the rotating shaft 10, and the second bevel gear 124 is meshed with the adjacent first bevel gear 123; In the process of treating the exhaust gas of the present invention, the cambered enclosure plate 5 and the cambered movable plate 7 can keep overlapping. When the exhaust gas enters the treatment tank 1 through the air inlet pipe 16, as the air suction component 4 works, the exhaust gas can enter the interior of the ceramic fiber tube 3 through the surface of the ceramic fiber tube 3 under the suction force of the air suction component 4, and then the filtered exhaust gas can be discharged from the treatment tank 1 through the exhaust pipe 15 under the action of the air suction component 4, and the dust in the exhaust gas can be gradually deposited on the surface of the ceramic fiber tube 3, and in the process of the ceramic fiber tube 3 filtering the exhaust gas, the drive motor 122 can be started intermittently. At this time, as the drive motor 122 is turned on, the exhaust gas is discharged from the treatment tank 1 through the exhaust pipe 15. The motor 122 drives the driving shaft 121 to rotate in the forward direction, and the first bevel gear 123 on the driving shaft 121 can drive the rotating shaft 10 to rotate through the second bevel gear 124 on the rotating shaft 10, and the one-way sleeve 13 at this time can drive the curved surface enclosure plate 5 to rotate together through the connecting rod 14, so that the curved surface enclosure plate 5 and the curved surface movable plate 7 can rotate around the ceramic fiber tube 3 together, thereby ensuring that the exhaust gas entering the treatment tank 1 can be evenly contacted with the surface of the ceramic fiber tube 3, avoiding the ceramic fiber tube 3 from affecting the exhaust gas treatment effect due to one side of the ceramic fiber tube 3 being blocked by the curved surface enclosure plate 5 or the curved surface movable plate 7; After the ceramic fiber tube 3 has filtered the exhaust gas for a period of time, as the driving motor 122 drives the driving shaft 121 to rotate in the opposite direction, the curved movable plate 7 can move together with the rotation of the rotating shaft 10, and the one-way sleeve 13 at this time can keep idling, so that the curved enclosure 5 remains stationary. As the curved movable plate 7 moves, when the curved movable plate 7 cooperates with the curved enclosure 5 to completely surround the ceramic fiber tube 3, the driving motor 122 stops. At this time, as the air compressor 42 presses compressed air from the top of the ceramic fiber tube 3 into the inside of the ceramic fiber tube 3, the dust adsorbed on the surface of the ceramic fiber tube 3 can fall off from the surface of the ceramic fiber tube 3, and then the fallen dust can be discharged through the bottom end of the circular tube surrounded by the curved enclosure 5 and the curved movable plate 7 and discharged from the treatment tank 1 by the induced draft fan 18 through the ash discharge pipe 17, thereby avoiding the deficiency of dust diffusion to the adjacent ceramic fiber tubes 3 under the existing cleaning method, and improving the cleaning efficiency and cleaning effect of the ceramic fiber tube 3; When the dust on the surface of the ceramic fiber tube 3 is cleaned, the driving motor 122 can continue to drive the driving shaft 121 to rotate in the opposite direction, so that the curved movable plate 7 can gradually overlap with the curved enclosure plate 5 again. When the curved movable plate 7 and the curved enclosure plate 5 are completely overlapped, the driving motor 122 can first stop and then drive the driving shaft 121 to rotate in the forward direction, thereby repeating the above working process.

[0019] like Figure 2 and Figure 4 As shown, the air intake assembly 4 includes a plurality of air intake pipes 41, and the plurality of air intake pipes 41 are respectively and one by one distributed on the tops of the plurality of rows of ceramic fiber tubes 3, and the top of the air intake pipe 41 in the middle is connected to an air compressor 42, and the air compressor 42 is connected to the exhaust pipe 15 at the top of the processing tank 1, and the air intake pipe 41 in the middle is separately connected to the remaining air intake pipes 41 by a connecting pipe 43, and a control valve 44 is installed on the connecting pipe 43, and the bottom of the air intake pipe 41 is vertically connected to a plurality of inserting pipes 45, and the plurality of inserting pipes 45 are respectively and one by one inserted into the top openings of the plurality of ceramic fiber tubes 3 at the bottom of the air intake pipe 41; By providing the air suction assembly 4, during the process of the ceramic fiber tube 3 in the treatment tank 1 filtering the waste gas, the control valves 44 on all the connecting pipes 43 can be kept in an open state, so that all the ceramic fiber tubes 3 can suck the waste gas in the treatment tank 1 into the interior of the ceramic fiber tube 3 for filtering under the suction force of the top insertion pipe 45 thereof, and then the filtered waste gas can be discharged from the treatment tank 1 through the exhaust pipe 15 under the action of the air compressor 42; After the ceramic fiber tube 3 has been filtered for a period of time, in order to ensure the filtering effect of the ceramic fiber tube 3, it is necessary to perform a pulse cleaning operation on the ceramic fiber tube 3. However, since a large number of ceramic fiber tubes 3 are generally provided in the treatment tank 1, and the power of the air compressor 42 is certain, the existing air compressor 42 is not effective in performing pulse cleaning on the ceramic fiber tube 3. At this time, by providing an air suction component 4, when performing a pulse cleaning operation on the ceramic fiber tube 3, the present invention can perform a separate pulse cleaning operation on each row of ceramic fiber tubes 3 in turn. The specific cleaning operation is as follows: When pulse cleaning operation is performed on one row of ceramic fiber tubes 3, first close all control valves 44 on the remaining connecting pipes 43 except the row where the ceramic fiber tubes 3 to be cleaned are located, then make the drive motor 122 at the bottom of the row of ceramic fiber tubes 3 to be cleaned rotate in the opposite direction, thereby driving the curved movable plate 7 of the row to cooperate with the curved surrounding plate 5 of the row to surround the multiple ceramic fiber tubes 3 to be cleaned, and then make the air compressor 42 perform compressed gas operation so that the outside air can be sucked into the air compressor 42, and then the air compressor 42 can reversely pump the compressed air into the row of ceramic fiber tubes 3 to be cleaned, thereby completing the pulse cleaning operation of the row of ceramic fiber tubes 3. Since the number of ceramic fiber tubes 3 to be cleaned is small, the air compressor 42 can apply a larger pulse pressure to the inside of the ceramic fiber tubes 3, thereby ensuring the pulse cleaning effect of the ceramic fiber tubes 3.

[0020] like Figures 3 to 6 As shown, a cleaning rod 19 is vertically fixedly connected between the two second fixing rings 8, and bristles 20 are evenly arranged on one side of the cleaning rod 19 close to the ceramic fiber tube 3, and the bristles 20 can contact the surface of the ceramic fiber tube 3; By providing a cleaning rod 19 and bristles 20, when the air compressor 42 performs pulse cleaning on the ceramic fiber tube 3, as the curved movable plate 7 cooperates with the curved surrounding plate 5 to surround the ceramic fiber tube 3, the cleaned dust can be discharged through the bottom end of the circular tube surrounded by the curved movable plate 7 and the curved surrounding plate 5. After the dust is discharged for a period of time, as the driving motor 122 drives the rotating shaft 10 to rotate through the driving shaft 121, the curved movable plate 7 can drive the cleaning rod 19 to move along the periphery of the ceramic fiber tube 3 through the two second fixed rings 8. During the movement of the cleaning rod 19, the bristles 20 on the cleaning rod 19 can clean and brush the surface of the ceramic fiber tube 3, thereby brushing off the dust remaining on the surface of the ceramic fiber tube 3, thereby improving the cleaning effect of the ceramic fiber tube 3.

[0021] like Figure 8 As shown, an annular mounting groove is provided on the inner side of the top edge of the jack, a support ring 21 is slidably installed in the mounting groove, and a support spring 22 is fixedly connected between the bottom of the support ring 21 and the bottom inner wall of the mounting groove; By providing the support spring 22 and the support ring 21, when the ceramic fiber tube 3 is inserted into the insertion hole on the dust separation plate 2, as the top protruding part of the ceramic fiber tube 3 contacts the support ring 21 from top to bottom, the support ring 21 can gradually compress the support spring 22 under the action of pressure, so that the ceramic fiber tube 3 can slowly move downward and complete the installation operation, thereby preventing the ceramic fiber tube 3 from being damaged due to collision with the insertion hole during the insertion of the ceramic fiber tube 3; In addition, when the insert tube 45 is docked with the ceramic fiber tube 3, as the insert tube 45 and the ceramic fiber tube 3 are plugged together, the ceramic fiber tube 3 can be tightly connected with the insert tube 45 under the supporting force of the support spring 22 on the support ring 21, thereby ensuring the airtightness of the connection between the insert tube 45 and the ceramic fiber tube 3, thereby improving the working efficiency of the air compressor 42.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
