Description

Technical Field

[0001] The utility model belongs to the technical field of flue gas desulfurization devices, and particularly relates to a desulfurized flue gas turbulence device. Background Art

[0002] A desulfurized flue gas turbulence device refers to a device used in a flue gas desulfurization system to improve the flow state of flue gas and enhance the desulfurization efficiency. Its main function is to increase the turbulence degree of flue gas, so that the flue gas can be more fully mixed with desulfurizing agents (such as limestone, gypsum, etc.), thereby improving the desulfurization efficiency.

[0003] When the existing flue gas turbulence devices are in use, in order to facilitate the treatment of flue gas, the flue gas usually directly enters the turbulence device and then is discharged through the smoke outlet pipe. Therefore, the flow velocity of the flue gas inside the turbulence device is very fast, making it impossible for the flue gas to fully react with the desulfurizing agent; and in order to enhance the stability of the nozzle, the position of the nozzle is usually fixedly installed inside the housing, thus easily resulting in the situation where the flue gas and the desulfurizing agent cannot be evenly mixed. Summary of the Invention

[0004] The purpose of the utility model is to provide a desulfurized flue gas turbulence device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A desulfurized flue gas turbulence device, comprising a smoke inlet pipe, a smoke outlet pipe and a water pump. One side of the smoke inlet pipe is connected with a housing, a turbulence plate is installed inside the housing, the smoke outlet pipe is installed on the side of the housing away from the smoke inlet pipe, a spraying rack is installed inside the housing, a diversion pipe is installed on the top of the spraying rack, and the water pump is connected to one side of the diversion pipe;

[0006] One side of the housing is installed with a driving motor through a protective shell, and the output end of the driving motor is connected with a driving shaft through a coupling.

[0007] Preferably, one side of the driving shaft is connected with a bevel gear set, and a rotating shaft penetrates through the middle of the bevel gear set.

[0008] Preferably, the top of the rotating shaft is connected with a turntable, and the top of the turntable is connected with a connecting rod.

[0009] Preferably, a connecting rod penetrating through the turbulence plate is connected between two groups of the spraying racks, a guiding block is installed at one end of the spraying rack close to the housing, and a sliding block is connected between the connecting rod and the sliding groove of the spraying rack.

[0010] Preferably, a fixing block is installed on the outer side of the smoke inlet pipe, and a telescopic block penetrates through one end of the fixing block.

[0011] Preferably, a plug rod penetrates through one side of the telescopic block, and a movable spring is connected between the plug rod and the telescopic block.

[0012] Preferably, a sealing ring is installed on the inner wall of the smoke inlet pipe through a groove, and a connecting pipe penetrating through the smoke inlet pipe is arranged on one side of the sealing ring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The turbulent flow plate in the outer shell of the present utility model plays a role in guiding the flue gas, prolonging the flow time of the flue gas in the outer shell, and then driving the connecting rod and the slider to move through the rotating shaft and the turntable. Under the action of the slider, the spraying rack makes a reciprocating motion, so that the desulfurization agent and the flue gas are evenly mixed, and then the flue gas is better desulfurized.

[0015] 2. When the flue gas needs to be transported to the outer shell through the smoke inlet pipe, the connecting pipe can be docked on one side of the smoke inlet pipe, and the telescopic block is pulled towards one side of the fixed block, and at the same time the plug rod is squeezed towards one side. When the connecting pipe is docked in the groove of the smoke inlet pipe, then the telescopic block is pushed into the groove of the fixed block, and at the same time the plug rod is released. At this time, the plug rod can be inserted outside the connecting pipe, and the connecting pipe squeezes the sealing ring in the groove of the smoke inlet pipe. The sealing performance between the smoke inlet pipe and the connecting pipe can be improved through the sealing ring, avoiding the leakage of the flue gas. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in 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 creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution: a desulfurization flue gas turbulence device, including an inlet smoke pipe 1, an outlet smoke pipe 4 and a water pump 7. One side of the inlet smoke pipe 1 is connected to an outer shell 2. A turbulence plate 3 is installed inside the outer shell 2. The outlet smoke pipe 4 is installed on the side of the outer shell 2 away from the inlet smoke pipe 1. A spraying rack 5 is installed inside the outer shell 2. A diversion pipe 6 is installed on the top of the spraying rack 5. The water pump 7 is connected to one side of the diversion pipe 6;

[0024] A driving motor 8 is installed on one side of the outer shell 2 through a protective shell. The output end of the driving motor 8 is connected to a driving shaft 9 through a coupling. One side of the driving shaft 9 is connected to a bevel gear set 10. A rotating shaft 11 runs through the middle of the bevel gear set 10. The top of the rotating shaft 11 is connected to a turntable 12. The top of the turntable 12 is connected to a connecting rod 13. A link 14 passing through the turbulence plate 3 is connected between the two spraying racks 5. A slider 22 is connected between the connecting rod 13 and the chute of the spraying rack 5. A guiding block 15 is installed at one end of the spraying rack 5 close to the outer shell 2. The slider 22 forms a sliding structure with the spraying rack 5 through the chute.

[0025] During specific implementation, the flue gas is transported into the outer shell 2 through the inlet smoke pipe 1. Two turbulence plates 3 are installed inside the outer shell 2. Therefore, under the action of the turbulence plates 3, the flue gas flows in an "S" shape along the turbulence plates 3, so that the flow time of the flue gas in the outer shell 2 can be extended;

[0026] Meanwhile, start the driving motor 8. The output end of the driving motor 8 drives the driving shaft 9 to rotate through a coupling, thereby driving the bevel gear set 10 to rotate. The bevel gear set 10 is connected by two meshing bevel gears. One bevel gear set 10 is connected to the driving shaft 9, and the other bevel gear set 10 is connected to the rotating shaft 11. Therefore, with the cooperation of the driving shaft 9 and the bevel gear set 10, the rotating shaft 11 drives the turntable 12 to rotate while rotating. A connecting rod 13 is installed on the top of the turntable 12, and the connecting rod 13 is installed on the outside of the turntable 12. Therefore, when the turntable 12 rotates, it will pull the connecting rod 13 to make a circular motion. The other end of the connecting rod 13 is slidably connected to the chute on one side of the spraying frame 5 through a slider 22;

[0027] When the turntable 12 drives the connecting rod 13 to rotate to the leftmost side, the slider 22 will slide along the chute of the spraying frame 5. At the same time, since the length of the connecting rod 13 is fixed, when the connecting rod 13 moves to the left, it will pull the spraying frame 5 to move to the left through the slider 22. When the turntable 12 drives the connecting rod 13 to rotate to the rightmost side, it will pull the spraying frame 5 to move to the right through the slider 22. Continuously repeat the above steps, and the spraying frame 5 can perform a reciprocating motion to the left and right. At the same time, the two spraying frames 5 are connected by a connecting rod 14, so that the three spraying frames 5 can move synchronously. The guiding block 15 can enhance the stability of the spraying frame 5 when moving. By continuously moving the spraying frame 5 to the left and right, the desulfurizer can be evenly sprayed into the flue gas inside the housing 2, so that the desulfurizer and the flue gas are evenly contacted and mixed, thereby improving the desulfurization effect of the desulfurizer.

[0028] Refer to Figures 1 to 3 As can be seen, during use, start the driving motor 8. With the cooperation of the driving shaft 9 and the bevel gear set 10, the rotating shaft 11 drives the turntable 12 to rotate. At the same time, the turntable 12 drives the spraying frame 5 to perform a reciprocating motion through the connecting rod 13 and the slider 22, so that the desulfurizer and the flue gas are evenly mixed, and the flow time of the flue gas is extended through the turbulence plate 3, thereby improving the desulfurization effect of the flue gas.

[0029] A fixing block 16 is installed on the outside of the smoke inlet pipe 1. One end of the fixing block 16 is connected through a telescopic block 17. One side of the telescopic block 17 is connected through a plug rod 18. An active spring 19 is connected between the plug rod 18 and the telescopic block 17. The inner wall of the smoke inlet pipe 1 is provided with a sealing ring 20 through a groove. One side of the sealing ring 20 is provided with a connecting pipe 21 penetrating the smoke inlet pipe 1. The plug rod 18 is inserted into the outside of the connecting pipe 21 through the groove.

[0030] During specific implementation, when it is necessary to introduce the flue gas into the outer shell 2, the connecting pipe 21 can be inserted into the smoke inlet pipe 1. At the same time, the telescopic block 17 is pulled outward toward the outside of the fixed block 16, so that the insertion rod 18 on one side of the telescopic block 17 releases the blockage of the connecting pipe 21, and the insertion rod 18 is pushed toward one side of the connecting pipe 21, so that the movable spring 19 between the insertion rod 18 and the telescopic block 17 is in a compressed state. Then the connecting pipe 21 can be inserted into the groove of the smoke inlet pipe 1. When the connecting pipe 21 is docked into the inside of the smoke inlet pipe 1, the telescopic block 17 can be pushed inward toward the inside of the fixed block 16. The telescopic block 17 moves, driving the insertion rod 18 to move to one side of the connecting pipe 21. At this time, the insertion rod 18 is released. The insertion rod 18 moves reversely along the telescopic block 17 under the reset action of the movable spring 19, and thus is inserted into the groove outside the connecting pipe 21. And through the cooperation of the movable spring 19 and the insertion rod 18, the connecting pipe 21 is extruded toward the direction of the smoke inlet pipe 1, and the connecting rod 13 squeezes the sealing ring 20 in the groove of the smoke inlet pipe 1. By squeezing the sealing ring 20, the sealing effect between the connecting pipe 21 and the smoke inlet pipe 1 can be improved, avoiding the leakage of flue gas, and at the same time facilitating the transportation of the flue gas through the smoke inlet pipe 1 into the outer shell 2.

[0031] Refer to Figure 2 and Figure 4 It can be seen that during use, the connecting pipe 21 can be docked into the groove on one side of the smoke inlet pipe 1 as needed. At the same time, the connecting pipe 21 is driven to move toward the direction of the smoke inlet pipe 1 through the insertion rod 18 and the movable spring 19, and the sealing ring 20 in the groove of the smoke inlet pipe 1 is squeezed, so as to facilitate the transportation of the flue gas into the outer shell 2 and avoid the leakage of flue gas at the same time.

[0032] In summary: When the present utility model is in use, the flue gas can be transported into the outer shell 2 through the smoke inlet pipe 1. A water pump 7 and a diversion pipe 6 are installed on the top of the outer shell 2. The water pump 7 can transport the desulfurizing agent through the diversion pipe 6 to the spraying rack 5, and the desulfurizing agent is sprayed out through the nozzles on the spraying rack 5, so that the desulfurizing agent is fully mixed with the flue gas in the outer shell 2, thereby playing a role in desulfurizing the flue gas. At the same time, the turbulence plate 3 can divert the flue gas into the smoke outlet pipe 4 on one side of the outer shell 2. The desulfurized flue gas is discharged from the outer shell 2 through the smoke outlet pipe 4, thus realizing the desulfurization of the flue gas. This is the usage feature of the desulfurization flue gas turbulence device. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
