Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization dust collectors, and specifically, to a desulfurization dust collector with a spraying device. Background Art

[0002] Chlorinated polyethylene is a saturated polymer material, with a white powder appearance, non-toxic and odorless, having excellent weather resistance, ozone resistance, chemical resistance and aging resistance, having good oil resistance, flame retardancy and coloring properties. When producing products from chlorinated polyethylene, chemicals such as sulfuric acid are required for reaction and demolding, and sulfur dioxide gas will be generated during this process. In order to avoid the impact of sulfur dioxide gas on the environment, desulfurization treatment is required.

[0003] After retrieval, the utility model patent with the publication number of CN220968778U discloses an efficient flue gas desulfurization dust collector, including a desulfurization tower. The middle part of the outer surface of the desulfurization tower is communicated with a dust inlet. A slurry chamber is arranged inside the desulfurization tower below the dust inlet. A circulating water pump is fixedly connected to one side surface of the desulfurization tower. A connecting pipe is communicated between the top end of the circulating water pump and a spraying frame. The bottom end of the circulating water pump is communicated with a water suction pipe penetrating to the inside of the bottom end of the desulfurization tower. A stirring rod is arranged inside the bottom end of the desulfurization tower. The stirring rod rotates in the slurry chamber through a driving assembly. A connecting column is fixedly installed on one side of the top of the stirring rod. Stirring rods are fixedly installed on the bottom surface of the connecting column at equal intervals; by setting the stirring rod, stirring rods and connecting column rotating inside the desulfurization tower, the slurry inside the desulfurization tower can be stirred and used, avoiding precipitation, so as to ensure the working efficiency during flue gas desulfurization.

[0004] However, the above patent still has the following deficiencies: After the filter cartridge is installed on the dust inlet and connected to the dust and sulfur oxide outlet, it is not convenient to replace and clean the filter cartridge. When the filter cartridge is blocked by dust, it affects the introduction of waste gas into the desulfurization tower, and the practicability is poor; in addition, the desulfurization effect by spraying only through one spraying frame is poor, and it is not easy to ensure complete desulfurization. For this reason, we propose a desulfurization dust collector with a spraying device. Summary of the Utility Model

A spraying mechanism 4 is arranged on the absorption tower 1. An agitation mechanism 2 is arranged at the bottom of the inner cavity of the absorption tower 1.

[0030] In this embodiment, the inner wall of the clamping groove 8 and the side surface of the clamping ring 13 are in contact with each other to ensure the sealing performance of the clamping ring 13 between the gas inlet pipe 5 and the arc-shaped cover 7.

[0031] Specifically, please refer to Figure 1 、 Figure 2 and Figure 4 , The spraying mechanism 4 includes a water extraction pipe 15 fixedly sleeved on the side of the absorption tower 1. A water extraction pump 16 is fixedly connected to the top end of the water extraction pipe 15. The output end of the water extraction pump 16 is fixedly connected to a main water guiding steel pipe 17. Two water guiding branch steel pipes 18 are fixedly connected to the main water guiding steel pipe 17. The ends of both water guiding branch steel pipes 18 extend into the inner cavity of the absorption tower 1 and are fixedly connected to a spraying pipe 19. A plurality of nozzles 20 are arranged on the bottom surface of the spraying pipe 19.

[0032] In this embodiment, the end of the water extraction pipe 15 is connected to the input end of the water extraction pump 16, so as to use the water extraction pump 16 to extract the lime water at the bottom of the inner cavity of the absorption tower 1, so that the lime water enters the spraying pipe 19 for spraying.

[0033] Specifically, please refer to Figure 2 and Figure 6 , The agitation mechanism 2 includes an installation box 21 fixedly connected to the bottom of the inner cavity of the absorption tower 1. A servo motor 22 is fixedly installed in the inner cavity of the installation box 21. The output shaft of the servo motor 22 extends to the top of the installation box 21 and is fixedly connected to a transmission frame 3. A stirring frame 23 is fixedly connected to the side of the transmission frame 3. A rotating shaft 24 is fixedly connected to the top of the transmission frame 3. A stirring blade 25 is fixedly connected to the top of the rotating shaft 24.

[0034] In this embodiment, the lime water at the bottom of the inner cavity of the absorption tower 1 is agitated by the stirring frame 23 to prevent the lime water from precipitating. The waste gas is agitated by the stirring blade 25 to ensure that the waste gas and the sprayed liquid droplets are in full contact.

[0035] Specifically, please refer to Figure 3, a discharge pipe 27 is fixedly sleeved on the top of the absorption tower 1, and a switching valve 28 is fixedly installed on the side of the absorption tower 1. The inner cavity of the switching valve 28 is fixedly sleeved to the bottom of the inner cavity of the absorption tower 1.

[0036] In this embodiment, the exhaust gas for desulfurization and dust removal is discharged through the switching valve 28, and the lime water at the bottom of the inner cavity of the absorption tower 1 is pumped out through the switching valve 28. Additionally, the end of the switching valve 28 can be connected to a water pump, so as to pump the external lime water from the water guiding branch steel pipe 18 into the inner cavity of the absorption tower 1 for desulfurization.

[0037] Specifically, please refer to Figure 2 , a demister 26 is arranged above the spray pipe 19 in the inner cavity of the absorption tower 1.

[0038] In this embodiment, the demister 26 is mainly composed of fixing devices such as corrugated blades, sheet plates, and clamping strips. During wet desulfurization, when the absorption tower 1 is in operation, "fog" with a particle size of 10 - 60 microns is easily generated. The "fog" not only contains moisture, but also dissolves sulfuric acid, sulfates, sulfur dioxide, etc. At the same time, it also causes fouling and serious corrosion of the fan, heat exchanger, and flue. Therefore, the wet desulfurization process puts forward the requirement of fog removal for the absorption equipment, and the purified gas needs to be demisted before leaving the absorption tower.

[0039] Specifically, please refer to Figure 1 , a connecting flange 29 is fixedly connected to the end of the intake pipe 5.

[0040] In this embodiment, the end of the intake pipe 5 is connected to the exhaust gas outlet through the connecting flange 29.

[0041] Working principle: When in use, firstly, the lime water is injected from the switch valve 28 into the bottom of the inner cavity of the absorption tower 1 through the external water pump, and the air inlet pipe 5 is connected to the exhaust outlet of the waste gas generated during the production of chlorinated polyethylene through the connecting flange 29, and then the servo motor 22 is started to drive the transmission frame 3, the stirring frame 23, the rotating shaft 24 and the stirring blade 25 to rotate, and the stirring frame 23 is used to stir the lime water at the bottom of the inner cavity of the absorption tower 1 to prevent the lime water from settling, and at the same time, the water pump 16 is started to make the water pump 15 generate suction, and the suction force of the water pump 15 is used to pump the lime water at the bottom of the inner cavity of the absorption tower 1 into the two spray pipes 19, and the nozzles 20 under the two spray pipes 19 spray the lime water downward, and then the waste gas is allowed to enter the absorption tower 1 from the air inlet pipe 5. The inner cavity, at the same time, the dust in the exhaust gas is filtered by the filter cartridge 14 in the inner cavity of the air inlet pipe 5. The exhaust gas entering the inner cavity of the absorption tower 1 is stirred and dispersed by the stirring blades 25, so that the dispersed exhaust gas contacts the sprayed lime water. In the process of the exhaust gas moving upward, it contacts the lime water sprayed under the two spray pipes 19 respectively, to ensure that the exhaust gas is fully desulfurized. The separated exhaust gas is discharged from the exhaust pipe 27. Finally, when desulfurization is not required, the butterfly screw 12 is rotated to disengage its bottom end from the inner cavity of the threaded hole 10 to release the fixation between the arc cover 7 and the air inlet pipe 5, thereby removing the arc cover 7 from the air inlet pipe 5, and then taking out the retaining ring 13 and the filter cartridge 14 from the inner cavity of the air inlet pipe 5, so as to clean the dust filtered out of the filter cartridge 14.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and improved concept of the present invention, which should be included in the protection scope of the present invention.
