Description

Technical Field

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

[0002] The integrated collaborative purification treatment process of sulfur, dust and nitrate in ceramic fiber tubes is a denitrification and dust removal treatment device widely used in industries such as glass, waste incineration, coking, and chemical engineering. When treating waste gas, lime powder is sprayed into the flue gas at the front section of the flue. After preliminary mixing through a static mixer, it enters the flue gas fluidized mixing tower, where a primary desulfurization reaction occurs. Then, through the flue behind the tower, diluted ammonia gas is sprayed through an ammonia injection grid. After being evenly distributed by a deflector plate, it enters the ceramic fiber filter cartridge. Larger dust particles settle under the action of gravity, and smaller dust particles deposit on the surface of the ceramic fiber filter cartridge, and a secondary desulfurization occurs on the dust cake layer on the surface of the ceramic fiber filter cartridge. The sulfur-free 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, and nitrogen oxides are removed once. Then, it is discharged through an induced draft fan. When the dust deposits on the surface of the ceramic fiber filter cartridge to a certain value, compressed air is used to pulse clean the filter cartridge.

[0003] When pulse cleaning the surface of the ceramic fiber filter cartridge, since there is no protective device on the outside of the existing ceramic fiber filter cartridge, during the pulse cleaning operation, the cleaned dust will spread to the surface of adjacent ceramic fiber filter cartridges, thereby affecting the cleaning efficiency and cleaning effect of the ceramic fiber filter cartridges. Summary of the Invention

[0004] In view of the above problems, the present invention provides a process for integrated collaborative purification treatment of sulfur, dust and nitrate in ceramic fiber tubes to solve the problems raised in the above background art.

A same fixing plate is horizontally arranged at the bottom of multiple fixing rods in the same row. Both ends of the fixing plate are fixedly connected to the inner wall of the treatment tank, and multiple rotating shafts in the same row are vertically inserted through the fixing plate at the bottom opposite thereto. A driving component for driving the rotating shaft to rotate is arranged at the bottom of the fixing plate. A one-way shaft sleeve is sleeved on the rotating shaft, and the idling direction of the one-way shaft sleeve is opposite to the positive rotation direction of the rotating shaft.

An exhaust pipe is connected to the top of the treatment tank, an air inlet pipe is connected to the side wall of the treatment tank, and a dust discharge pipe is connected to the bottom of the treatment tank, and an induced draft fan is installed on the dust discharge pipe.

[0007] Further, the air suction component includes multiple suction pipes. The multiple suction pipes are respectively and correspondingly distributed at the top of multiple rows of ceramic fiber tubes. An air compressor is connected to the top of the suction pipe in the middle. The air compressor is connected to the exhaust pipe at the top of the treatment tank. Separate connecting pipes are connected between the suction pipe in the middle position and the remaining suction pipes, and control valves are installed on the connecting pipes. Multiple insertion pipes are vertically connected to the bottom of the suction pipe, and the multiple insertion pipes are respectively and correspondingly inserted into the top openings of the multiple ceramic fiber tubes directly below the suction pipe.

[0008] Further, the driving component includes a driving shaft. The driving shaft is horizontally arranged at the bottom of the fixing plate, and one end of the driving shaft is drivingly connected with a driving motor. Fixing blocks are rotatably sleeved at positions near both ends of the driving shaft, and the fixing blocks are fixedly connected to the bottom of the fixing plate. Multiple first bevel gears are sleeved on the driving shaft, and the multiple first bevel gears are respectively opposite to multiple rotating shafts on the fixing plate. A second bevel gear is fixedly sleeved at the bottom end of the rotating shaft, and the second bevel gear meshes with the adjacent first bevel gear.

[0009] Further, a cleaning rod is vertically and fixedly connected between the two second fixing rings. A plurality of bristles are evenly arranged on one side of the cleaning rod close to the ceramic fiber tube, and the bristles can contact the surface of the ceramic fiber tube.

[0010] Further, an annular mounting groove is formed in the inner side of the top edge of the jack. A support ring is slidably mounted in the mounting groove, and a support spring is fixedly connected between the bottom of the support ring and the inner wall of the bottom of the mounting groove.

[0011] Further, the arc length of the arc-shaped movable plate is the same as that of the arc-shaped surrounding plate, and the arc lengths of the arc-shaped movable plate and the arc-shaped surrounding plate are both greater than half of the circumference of the circle where they are located.

At this time, as the air compressor performs pulse dust cleaning on the ceramic fiber tube, the dust removed can be discharged from the bottom end of the circular tube formed by the arc-shaped surrounding plate and the arc-shaped movable plate and is discharged from the treatment tank by the induced draft fan through the ash discharge pipe, thus avoiding the deficiency that dust diffuses to adjacent ceramic fiber tubes in the existing dust cleaning method, and improving the dust cleaning efficiency and effect of the ceramic fiber tube;

[0017] 2. By providing the air suction assembly, when performing pulse dust cleaning on the ceramic fiber, the present invention can perform separate pulse dust cleaning operations on each row of ceramic fiber tubes in sequence. Since the number of ceramic fiber tubes to be cleaned is small, the air compressor can apply a greater pulse pressure to the inside of the ceramic fiber tube, thereby ensuring the pulse dust cleaning effect on the ceramic fiber tube;

[0018] 3. In the present invention, by providing a cleaning rod and bristles, when the air compressor performs pulse dust cleaning on the ceramic fiber tube, as the arc-shaped movable plate cooperates with the arc-shaped surrounding plate to enclose the ceramic fiber tube, the dust removed can be discharged from the bottom end of the circular tube formed by the arc-shaped movable plate and the arc-shaped surrounding plate. After the dust is discharged for a period of time, as the driving motor drives the rotating shaft to rotate through the driving shaft, the arc-shaped movable plate can drive the cleaning rod to move along the periphery of the ceramic fiber tube through two second fixing rings. During the movement of the cleaning rod, the bristles on the cleaning rod can brush and wash against the surface of the ceramic fiber tube, thereby brushing off the dust remaining on the surface of the ceramic fiber tube and improving the dust cleaning effect on the ceramic fiber tube.

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides as Figures 1 to 8A process for the integrated collaborative purification treatment of sulfur, dust, and nitrate in ceramic fiber tubes is shown, which is applied to a collaborative purification treatment device. The collaborative purification treatment device includes a treatment tank 1. Inside the treatment tank 1, a dust separation plate 2 is horizontally arranged. The top of the dust separation plate 2 is provided with multiple rows of jacks, and the number of jacks in each row is multiple. Ceramic fiber tubes 3 are inserted into the jacks. At the top of multiple rows of ceramic fiber tubes 3, an air suction component 4 is arranged. Around the bottom of the ceramic fiber tubes 3 outside the dust separation plate 2, an arc-shaped enclosing plate 5 coaxial with the ceramic fiber tubes 3 is arranged. At the top and bottom ends of the arc-shaped enclosing plate 5, first fixing rings 6 are fixedly connected. And the first fixing ring 6 at the top is rotatably connected to the bottom of the dust separation plate 2. Inside the arc-shaped enclosing plate 5, an arc-shaped movable plate 7 coaxial with it is arranged. At the top and bottom ends of the arc-shaped movable plate 7, second fixing rings 8 are fixedly connected. Both of the two second fixing rings 8 are rotatably installed inside the arc-shaped enclosing plate 5. Inside the second fixing ring 8 at the bottom, a fixing rod 9 is fixedly connected. At the center of the bottom of the fixing rod 9, a rotating shaft 10 is vertically fixedly connected. At the bottom of multiple fixing rods 9 in the same row, a same fixing plate 11 is horizontally arranged. Both ends of the fixing plate 11 are fixedly connected to the inner wall of the treatment tank 1. And multiple rotating shafts 10 in the same row are vertically inserted through the fixing plate 11 opposite at the bottom. At the bottom of the fixing plate 11, a driving component 12 for driving the rotating shaft 10 to rotate is arranged. A one-way shaft sleeve 13 is sleeved on the rotating shaft 10, and the idling direction of the one-way shaft sleeve 13 is opposite to the positive rotation direction of the rotating shaft 10. Between the one-way shaft sleeve 13 and the first fixing ring 6 at the bottom, multiple L-shaped connecting rods 14 are fixedly connected. The top of the treatment tank 1 is connected with an exhaust pipe 15. The side wall of the treatment tank 1 is connected with an air inlet pipe 16. The bottom of the treatment tank 1 is connected with an ash discharge pipe 17, and an induced draft fan 18 is installed on the ash discharge pipe 17. The diameter of the treatment tank 1 near the bottom end 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 arc-shaped movable plate 7 is the same as the arc length of the arc-shaped enclosing plate 5, and the arc lengths of both the arc-shaped movable plate 7 and the arc-shaped enclosing plate 5 are 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 supporting ring 21. The bottom end of the ceramic fiber tube 3 is higher than the bottom of the arc-shaped movable plate 7. There is a gap between the arc-shaped movable plate 7 and the ceramic fiber tube 3. There is also a gap between adjacent two arc-shaped enclosing plates 5;

[0030] The driving assembly 12 includes a driving shaft 121 which is horizontally arranged at the bottom of the fixing plate 11. One end of the driving shaft 121 is drivingly connected to a driving motor 122. Fixing blocks are rotatably sleeved at positions of the driving shaft 121 near both ends, and the fixing blocks are fixedly connected to the bottom of the fixing plate 11. 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 a plurality of rotating shafts 10 on the fixing plate 11. A second bevel gear 124 is fixedly sleeved at the bottom end of the rotating shaft 10, and the second bevel gear 124 is meshed with the adjacent first bevel gear 123;

[0031] In the process of the present invention for treating waste gas, the arc-shaped enclosing plate 5 and the arc-shaped movable plate 7 can remain coincident. When the waste gas enters the treatment tank 1 through the intake pipe 16, with the operation of the suction assembly 4, the waste 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 suction assembly 4. Subsequently, the filtered waste gas can be discharged from the treatment tank 1 through the exhaust pipe 15 under the action of the suction assembly 4, and the dust in the waste gas can gradually deposit on the surface of the ceramic fiber tube 3. And during the process of the ceramic fiber tube 3 filtering the waste gas, the driving motor 122 can be intermittently started. At this time, as the driving motor 122 drives the driving shaft 121 to rotate forward, 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 at this time the one-way shaft sleeve 13 can drive the arc-shaped enclosing plate 5 to rotate together through the connecting rod 14, so that the arc-shaped enclosing plate 5 and the arc-shaped movable plate 7 can rotate around the ceramic fiber tube 3 together, thereby ensuring that the waste gas entering the treatment tank 1 can uniformly contact the surface of the ceramic fiber tube 3, and avoiding the influence on the waste gas treatment effect of the ceramic fiber tube 3 due to a certain surface of the ceramic fiber tube 3 being blocked by the arc-shaped enclosing plate 5 or the arc-shaped movable plate 7;

[0032] After the ceramic fiber tube 3 filters the waste gas for a period of time, as the driving motor 122 drives the drive shaft 121 to rotate in the reverse direction, the arc-shaped movable plate 7 can move along with the rotation of the rotating shaft 10. At this time, the one-way bushing 13 can rotate idly, so that the arc-shaped enclosing plate 5 remains stationary. As the arc-shaped movable plate 7 moves, when the arc-shaped movable plate 7 cooperates with the arc-shaped enclosing plate 5 to completely enclose the ceramic fiber tube 3, the driving motor 122 stops. At this time, as the air compressor 42 presses compressed air into the interior of the ceramic fiber tube 3 from the top 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. Subsequently, the fallen dust can be discharged through the bottom end of the circular tube formed by the arc-shaped enclosing plate 5 and the arc-shaped movable plate 7 and is discharged from the treatment tank 1 by the induced draft fan 18 through the ash discharge pipe 17, thus avoiding the deficiency that dust diffuses to the adjacent ceramic fiber tube 3 in the existing ash cleaning method and improving the cleaning efficiency and cleaning effect of the ceramic fiber tube 3;

[0033] When the dust on the surface of the ceramic fiber tube 3 is completely cleaned, the driving motor 122 can continue to drive the drive shaft 121 to rotate in the reverse direction, so that the arc-shaped movable plate 7 can gradually coincide with the arc-shaped enclosing plate 5 again. When the arc-shaped movable plate 7 completely coincides with the arc-shaped enclosing plate 5, the driving motor 122 can first stop and then drive the drive shaft 121 to rotate in the forward direction, and then repeat the above working process.

[0034] As Figure 2 and Figure 4 As shown, the air suction assembly 4 includes a plurality of suction pipes 41. The plurality of suction pipes 41 are respectively distributed at the tops of multiple rows of ceramic fiber tubes 3 one by one. And the top of the suction pipe 41 in the middle is connected with an air compressor 42. The air compressor 42 is connected with the exhaust pipe 15 at the top of the treatment tank 1. Separate connecting pipes 43 are connected between the suction pipe 41 in the middle position and the other suction pipes 41. And a control valve 44 is installed on the connecting pipe 43. The bottom of the suction pipe 41 is vertically connected with a plurality of inserting pipes 45. The plurality of inserting pipes 45 are respectively inserted into the top openings of a plurality of ceramic fiber tubes 3 directly below the suction pipe 41 one by one;

[0035] By providing the air suction assembly 4, during the process of filtering the waste gas by the ceramic fiber tubes 3 in the treatment tank 1, the control valves 44 on all the connecting pipes 43 can all be kept in the 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 tubes 3 under the suction of the inserting pipes 45 at their tops for filtering treatment. Subsequently, 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;

[0036] When the ceramic fiber tube 3 has undergone a filtration operation for a period of time, in order to ensure the filtration effect of the ceramic fiber tube 3, it is necessary to perform pulse dust cleaning on the ceramic fiber tube 3. However, since there are many ceramic fiber tubes 3 in the general treatment tank 1 and the power of the air compressor 42 is fixed, the existing air compressor 42 has poor effect when performing pulse dust cleaning on the ceramic fiber tube 3. At this time, by providing an air suction assembly 4, when performing pulse dust cleaning on the ceramic fiber tube 3, the present invention can perform separate pulse dust cleaning operations on each row of ceramic fiber tubes 3 in sequence. The specific dust cleaning operation is as follows:

[0037] When performing pulse dust cleaning on one row of ceramic fiber tubes 3, first close all the control valves 44 on the remaining connecting pipes 43 except the row where the ceramic fiber tube 3 to be cleaned is located. Then, reverse the driving motor 122 at the bottom of the row of ceramic fiber tubes 3 to be cleaned, so as to drive the arc-shaped movable plate 7 of this row to cooperate with the arc-shaped enclosing plate 5 of this row to enclose the multiple ceramic fiber tubes 3 to be cleaned. Subsequently, the air compressor 42 performs compressed gas operation, so that the outside air can be sucked into the air compressor 42. Then, the air compressor 42 can pump the compressed air reversely into the row of ceramic fiber tubes 3 to be cleaned, thereby completing the pulse dust cleaning operation on this 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 greater pulse pressure inside the ceramic fiber tube 3, thereby ensuring the pulse dust cleaning effect on the ceramic fiber tube 3.

[0038] As Figures 3 to 6 shown, a cleaning rod 19 is vertically and fixedly connected between the two second fixing rings 8. A plurality of brush hairs 20 are evenly arranged on one side of the cleaning rod 19 close to the ceramic fiber tube 3, and the brush hairs 20 can contact the surface of the ceramic fiber tube 3;

[0039] By providing the cleaning rod 19 and the brush hairs 20, when the air compressor 42 performs pulse dust cleaning on the ceramic fiber tube 3, as the arc-shaped movable plate 7 cooperates with the arc-shaped enclosing plate 5 to enclose the ceramic fiber tube 3, the dust removed can be discharged from the bottom end of the circular tube formed by the arc-shaped movable plate 7 and the arc-shaped enclosing plate 5. After the dust is discharged for a period of time, as the driving motor 122 drives the rotating shaft 10 through the driving shaft 121, the arc-shaped movable plate 7 can drive the cleaning rod 19 to move along the periphery of the ceramic fiber tube 3 through the two second fixing rings 8. During the movement of the cleaning rod 19, the brush hairs 20 on the cleaning rod 19 can brush and wash along the surface of the ceramic fiber tube 3, thereby brushing off the dust remaining on the surface of the ceramic fiber tube 3 and improving the dust cleaning effect on the ceramic fiber tube 3.

[0040] As Figure 8As shown, an annular installation groove is formed in the inner side of the top edge of the jack. A support ring 21 is slidably installed in the installation groove, and a support spring 22 is fixedly connected between the bottom of the support ring 21 and the bottom inner wall of the installation groove;

[0041] By providing the support spring 22 and the support ring 21, when the ceramic fiber tube 3 is inserted into the jack on the dust separation plate 2, as the protruding part at the top 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 avoiding damage to the ceramic fiber tube 3 due to collision with the jack during the insertion process of the ceramic fiber tube 3;

[0042] In addition, when the insertion tube 45 is butted against the ceramic fiber tube 3, as the insertion tube 45 is inserted into the ceramic fiber tube 3, the ceramic fiber tube 3 can be tightly connected to the insertion 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 insertion tube 45 and the ceramic fiber tube 3, and further improving the working efficiency of the air compressor 42.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them.
