Description

Technical Field

[0001] The utility model relates to the technical field of flue gas spraying in a desulfurization tower, in particular to a device for improving the reaction in a desulfurization tower. Background Art

[0002] The flue gas generated by industrial production contains sulfides and particulate matter, so it cannot be discharged directly. The flue gas needs to be desulfurized and dusted. Commonly used desulfurization and dust removal devices include spray towers, cyclone plate towers and bubbling towers. The general process is to transport the flue gas to a spray tower, cyclone plate tower or bubbling tower, and then spray the corresponding desulfurization reactants or water through the spray mechanism inside to desulfurize and dust the flue gas flowing from bottom to top. The flue gas can only be discharged after the desulfurization and dust removal treatment is completed.

[0003] The desulfurization tower is a widely used equipment for flue gas desulfurization and dust removal. The flue gas flows from bottom to top in it, and the spray pipe sprays the corresponding desulfurization reactants or water to complete the spray reaction. However, in the actual spraying process, in order to meet the requirements of protecting the inner wall of the tower body, the design angle of the nozzle of the spray pipe is relatively strict, so that the nozzle cannot be directly aimed at the inner wall of the tower body. Therefore, part of the flue gas along the inner wall of the tower body cannot pass through the spraying area of ​​the nozzle, that is, this part of the flue gas escapes along the inner wall of the tower body, which weakens the desulfurization and dust removal effect of the flue gas and may cause problems such as excessive emission values.

[0004] Therefore, it is necessary to invent a device for improving the reaction in the desulfurization tower to solve the above problems. Utility Model Content

Therefore, part of the flue gas along the inner wall of the tower body cannot pass through the spraying area of ​​the nozzle, that is, this part of the flue gas escapes along the inner wall of the tower body, thereby weakening the desulfurization and dust removal effect of the flue gas, and may cause problems such as excessive emission values.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A device for improving the reaction in a desulfurization tower comprises a tower body with open ends at the top and the bottom, a tower support detachably connected to the bottom end of the tower body, and a tower cover detachably connected to the top end of the tower body, wherein a vertical pipe is detachably inserted in the center of the tower cover, a plurality of horizontal pipes are connected to longitudinally equidistant positions of the outer peripheral side walls of the vertical pipe, a plurality of nozzles for spraying downwards are connected to the bottom side of the peripheral side walls of each of the horizontal pipes, a U-shaped cylinder is detachably clamped on the inner peripheral side walls of the tower body, a vertical groove is longitudinally opened on the peripheral side walls of the U-shaped cylinder near the center of the tower body, a screw is rotatably arranged in the U-shaped cylinder, a slip ring that can slide longitudinally along the vertical groove is threadedly penetrated in the part of the screw below each horizontal pipe, and the longitudinal spacing between the plurality of slip rings and the corresponding horizontal pipes is consistent, an annular baffle with a triangular cross-section is connected to the end of the slip ring near the center of the tower body, and an annular scraper that can longitudinally slide and abut against the peripheral side walls of the tower body is connected to the outer peripheral side walls of the annular baffle.

[0009] As a preferred solution of the utility model, the bottom end of the screw is rotatably abutted against the top surface of the support plate, and the top end of the screw is extended to form a rotating column, which rotates longitudinally in sequence to penetrate the top plate and the tower cover and extend to above the tower cover.

[0010] As a preferred solution of the utility model, a connecting block is connected to one side of the sliding ring peripheral side wall close to the center of the tower body, the connecting block can slide longitudinally along the vertical groove, and the other end of the connecting block is detachably connected to the outer peripheral side wall of the annular baffle.

[0011] As a preferred solution of the utility model, the top plate and the tower cover are both provided with round holes at positions adapted to the rotating column, a sleeve is detachably embedded in the round hole, and the rotating column is rotatably inserted into the sleeve.

[0012] As a preferred solution of the utility model, the bottom end of the vertical pipe is abutted against the center of the top surface of the tower support, the bottom surface of the tower support is connected to a smoke inlet pipe that can transport smoke into the tower body, and the top surface of the tower cover is connected to a smoke outlet pipe that can discharge smoke to the outside.

The sliding abutment blocks the escape path of the smoke along the inner wall of the tower body, and the smoke originally escaping along the inner wall of the tower body changes its upward angle due to the impact with the annular scraper and the annular baffle under the obstruction of the annular scraper and the annular baffle, that is, the smoke changes its angle and enters the spray reaction zone formed by multiple transverse tubes and multiple nozzles, so that the smoke completes multiple spray reactions under the transverse tubes at different longitudinal positions in the process of moving from bottom to top. Under the premise of preventing part of the smoke from escaping the spray reaction along the inner wall of the tower body, the overall spray reaction rate and effect of the smoke are improved through multiple spraying.

The end of the slip ring 16 close to the center of the tower body 1 is connected to an annular baffle 18 with a triangular cross-section, and the outer peripheral side wall of the annular baffle 18 is connected to an annular scraper 19 that can longitudinally slide and abut against the inner peripheral side wall of the tower body 1. A spray reaction zone at this height is formed between multiple transverse tubes 7 at equal longitudinal positions and multiple nozzles 8 thereon. In the process of smoke moving from bottom to top, it will pass through multiple spray reaction zones in turn, thereby completing multiple spray reactions.

[0020] The bottom end of the U-shaped cylinder 11 is detachably connected to a support plate 9, the bottom surface of the support plate 9 abuts against the top end of the tower support 2, and the top end of the U-shaped cylinder 11 is detachably connected to a top plate 10, the top surface of the top plate 10 abuts against the bottom surface of the tower cover 3. The support plate 9 and the top plate 10 can provide a connection bearing position between the U-shaped cylinder 11 and the tower support 2 and the tower cover 3, thereby allowing the U-shaped cylinder 11 to be stably inserted in the tower body 1.

[0021] The bottom end of the screw rod 13 is rotatably abutted against the top surface of the support plate 9, and a rotating column 14 is formed on the top end of the screw rod 13.

Under the limitation of the vertical groove 12, the slip ring 16 slides longitudinally along the screw rod 13.

[0022] A connecting block 17 is connected to one side of the side wall of the slip ring 16 close to the center of the tower body 1. The connecting block 17 can slide longitudinally along the vertical groove 12. The other end of the connecting block 17 is detachably connected to the outer peripheral side wall of the annular baffle 18. The connecting block 17 is in the vertical groove 12 so that the connecting block 17 can only slide longitudinally along the vertical groove 12. Therefore, under the longitudinal sliding limit of the connecting block 17, when the screw 13 rotates, the slip ring 16 can only slide longitudinally along the screw 13.

During the spraying process, the screw 13 is rotated according to different smoke intake amounts, so that the slip ring 16 slides longitudinally along the screw 13 by different distances, thereby changing the distance between the annular baffle 18 on the side wall of the slip ring 16 and the corresponding horizontal pipe 7. In the process of the annular baffle 18 changing the distance from the horizontal pipe 7, the annular scraper 19 is moved to the tower body. 1 longitudinally slides against the inner wall of the tower body 1, thereby blocking the escape path of the smoke along the inner wall of the tower body 1, and under the obstruction of the annular scraper 18 and the annular baffle 19, the smoke originally escaping along the inner wall of the tower body 1 changes its upward movement angle due to the collision with the annular scraper 18 and the annular baffle 19, that is, the smoke changes its angle and enters the spray reaction area formed by the multiple transverse tubes 7 and the multiple nozzles 8, so that the smoke completes multiple spray reactions under the transverse tubes 7 at different longitudinal positions during the process of moving from bottom to top, and on the premise of preventing part of the smoke from escaping the spray reaction along the inner wall of the tower body 1, the overall spray reaction rate and effect of the smoke are improved through multiple spraying.
