Description

TECHNICAL FIELD

[0002] Desulfurization mainly refers to the process of removing sulfur dioxide from waste gas generated in the process of combustion or industrial production; denitrification refers to the process of removing nitrogen oxides from waste gas.

[0003] When flue gas is treated by desulfurization and denitrification, a desulfurization and denitrification emission integrated tower is often used. Although the existing desulfurization and denitrification emission integrated tower can realize basic desulfurization and denitrification function in actual use, it is necessary to first carry out filtering and impurity removing operation on flue gas to remove solid impurity particles before desulfurization and denitrification. The filter screen plate is usually fixed at a specific position inside the desulfurization and denitrification emission integrated tower. This fixed installation method brings great inconvenience. When the filter screen plate intercepts a large amount of impurities in the long-term use process, it is difficult to disassemble, which leads to great difficulty in cleaning work. With the passage of time, impurities continue to accumulate, and the mesh of the filter screen plate will be gradually blocked, which will significantly increase the resistance of flue gas when passing through, thereby greatly reducing the efficiency of the entire desulfurization and denitrification process, and cannot meet the actual needs of efficient flue gas treatment. Therefore, it needs to be improved. CONTENT OF THE UTILITY MODEL

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides an integrated flue gas desulfurization and denitrification emission tower, including a base 1. A desulfurization and denitrification tower 2 is fixedly connected to the top of the base 1. A filter screen plate 3 is movably installed inside the desulfurization and denitrification tower 2. A pull rod 4 is fixedly connected inside the filter screen plate 3. A protective shell 5 located in front of the desulfurization and denitrification tower 2 is fixedly connected to the top of the base 1. A drive motor 6 is fixedly installed inside the protective shell 5. A rotating shaft 7 is fixedly sleeved at the other end of the output shaft of the drive motor 6. The right side of the rotating shaft 7 passes through the protective shell 5 and extends to the outside of the protective shell 5 and is fixedly sleeved with a rotating block 8. A connecting rod 9 is hinged to the other end of the rotating block 8. A connecting block 10 is hinged to the other end of the connecting rod 9. The outer surface of the connecting block 10 is movably connected to the inner wall of the desulfurization and denitrification tower 2. A baffle 11 is fixedly connected to the back of the connecting block 10. The outer surface of the baffle 11 is movably connected to the inner wall of the desulfurization and denitrification tower 2.

[0024] When the drive motor 6 is running, the rotating shaft 7 will drive the rotating block 8 to rotate, which in turn will cause the connecting rod 9 to rotate and drive the connecting block 10 to move downward. This will cause the baffle 11 to move downward and release the sealing effect on the filter screen 3. At this time, pulling the pull rod 4 outward can achieve the purpose of quickly disassembling and replacing the filter screen 3.

[0025] The desulfurization and denitrification tower 2 has an air inlet 12 fixedly connected to its back side and an exhaust port 13 fixedly connected to its top side.

[0026] Flue gas enters the interior of the desulfurization and denitrification tower 2 through the air inlet 12. After being treated for desulfurization and denitrification, the flue gas is discharged to the outside through the exhaust port 13.

[0027] The base 1 has a groove 14 on its top, a movable plate 15 is movably connected inside the groove 14, and a liquid collection tank 16 is fixedly connected to the top of the movable plate 15.

[0028] This design allows the liquid collection tank 16 to move horizontally under the limiting effect of the slide 14 and the movable plate 15.

[0029] The top of the liquid collection tank 16 is fixedly connected to a water pump 17, the right side of the water pump 17 is fixedly connected to a suction pipe 18, the bottom of the suction pipe 18 passes through the liquid collection tank 16 and extends into the interior of the liquid collection tank 16, the top of the water pump 17 is fixedly connected to a drain pipe 19, the right side of the drain pipe 19 passes through the desulfurization and denitrification tower 2 and extends into the interior of the desulfurization and denitrification tower 2 and is fixedly connected to a nozzle 20.

[0030] When the water pump 17 is running, the suction pipe 18 will draw the absorbent liquid from the collection tank 16, and then the liquid will be transported to the inside of the nozzle 20 by the discharge pipe 19. Finally, the nozzle 20 will spray the liquid out to treat the flue gas for desulfurization and denitrification.

[0031] The top of the liquid collection tank 16 is fixedly connected to the liquid guide pipe 21 on the left side of the water pump 17, and the inside of the liquid guide pipe 21 is connected to the inside of the liquid collection tank 16.

[0032] This design facilitates the addition of absorbent liquid to the inside of the collection tank 16 via the liquid guide tube 21.

[0033] The base 1 is fixedly connected to a drive motor 22 located in front of the collection tank 16. The other end of the output shaft of the drive motor 22 is fixedly sleeved with a drive shaft 23. The outer surface of the drive shaft 23 is fixedly sleeved with a rotating rod 24. The back of the rotating rod 24 is movably connected to the front of the collection tank 16. The inner surface of the rotating rod 24 is movably connected with a round shaft 25. The back of the round shaft 25 is fixedly connected to the front of the collection tank 16.

[0034] When the drive motor 22 is running, the drive shaft 23 will drive the rotating rod 24 to rotate, which in turn causes the rotating rod 24 to rotate and squeeze, driving the round shaft 25 to move left and right. This causes the liquid collection tank 16 to drive the nozzle 20 to move left and right, thus achieving the purpose of more comprehensive spraying of the absorbent liquid inside the nozzle 20.

[0035] Among them, a valve 26 is fixedly installed at the bottom right side of the desulfurization and denitrification tower 2, and a connecting pipe 27 is fixedly connected to the right side of the valve 26.

[0036] Opening valve 26 allows the absorbent liquid at the bottom of desulfurization and denitrification tower 2 to be discharged to the outside through connecting pipe 27.

[0037] Working principle and usage process of this utility model:

[0038] When treating flue gas for desulfurization and denitrification, the flue gas is first transported to the inside of the desulfurization and denitrification tower 2 through the inlet 12. After preliminary filtration by the filter screen 3, the flue gas rises upward. At this time, the water pump 17 is started, which causes the suction pipe 18 to draw the absorbent liquid from the collection tank 16, and then transport it to the inside of the nozzle 20 through the discharge pipe 19. Finally, the nozzle 20 sprays the liquid to treat the flue gas for desulfurization and denitrification. At the same time, the drive motor 22 is started, which causes the drive shaft 23 to drive the rotating rod 24 to rotate. The rotating rod 24 rotates and squeezes the circular shaft 25 to move left and right, which causes the collection tank 16 to drive the nozzle 20 to move left and right. This achieves the purpose of more comprehensive spraying of the absorbent liquid inside the nozzle 20, improving the desulfurization and denitrification effect of the flue gas. After treatment, the flue gas is discharged to the outside through the exhaust port 13, and the absorbent liquid falls to the bottom of the desulfurization and denitrification tower 2 for collection. At this time, the valve 26 is opened, and the absorbent liquid at the bottom of the desulfurization and denitrification tower 2 is discharged to the outside through the connecting pipe 27.

[0039] When a large amount of fixed impurities are adsorbed inside the filter screen 3, it needs to be replaced. First, start the drive motor 6, which will cause the rotating shaft 7 to drive the rotating block 8 to rotate, which in turn causes the connecting rod 9 to rotate and drive the connecting block 10 to move downward. This causes the baffle 11 to move downward and release the sealing effect on the filter screen 3. Then, pull the lever 4 to move it outward to achieve the purpose of quickly disassembling the filter screen 3. After that, put the new filter screen 3 into the desulfurization and denitrification tower 2. At this time, start the drive motor 6 again to drive the baffle 11 to reset and seal the filter screen 3, ensuring the overall sealing of the desulfurization and denitrification tower 2 and preventing the leakage of flue gas.
