Description

Technical Field

[0001] The utility model relates to the field of desulfurization towers, in particular to an anti-smoke-pollution and noise-reducing desulfurization tower. Background Technique

[0002] With the development of society, people's awareness of environmental protection is getting stronger and stronger, and the requirements for the treatment of industrial pollution are also constantly increasing. Sulfur dioxide is one of the main substances causing air pollution and is very harmful to human health. China has listed sulfur dioxide as a major regulated air pollutant and uses the concentration level of sulfur dioxide in the atmosphere as an important indicator for evaluating air quality. 80-90% of the sulfur dioxide in the atmosphere comes from industrial pollution emissions. Therefore, as an important device in the industrial flue gas desulfurization system, desulfurization towers are widely used.

[0003] When a coal-fired boiler burns, various organic and inorganic sulfurs contained in the coal are converted into sulfur oxides mainly composed of sulfur dioxide. Sulfur dioxide enters the atmosphere and combines with water in the atmosphere to form acid rain, which not only has a serious impact on ground buildings and crops but also harms people's bodies. Therefore, flue gas desulfurization is an important part of environmental protection. The main method of flue gas desulfurization is wet desulfurization, which uses slurries such as limestone as detergents to wash the flue gas in the desulfurization tower, thereby absorbing sulfur dioxide in the flue gas.

[0004] The absorption liquid is collected inside the desulfurization tower. However, after being used for a certain period of time, a large amount of reactants will be generated in the desulfurization tower, and the concentration of limestone slurry in the desulfurization tower will become higher and higher, resulting in more and more solids inside the desulfurization tower. In severe cases, it will affect the blockage of the desulfurization tower, reduce the desulfurization efficiency, and make the flue gas desulfurization effect unsatisfactory. To prevent smoke pollution, a cleaning device is used to clean the inner wall. Application No.: CN202222771793.X provides an anti-smoke-pollution and noise-reducing desulfurization tower, which can effectively and efficiently clean the inner wall of the tower body through two mutually perpendicular cleaning directions, thus greatly improving the working efficiency of the cleaning mechanism. However, when this device is used, the time for the flue gas to stay inside the desulfurization tower is short, resulting in a poor desulfurization effect, and the sprayed liquid medicine cannot be reused, with poor environmental protection.

Detailed Description of the Preferred Embodiments

[0021] The following further describes the utility model in conjunction with the drawings and embodiments.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , where Figure 1 is a schematic structural diagram of a preferred embodiment of an anti-smoke-pollution noise-reducing desulfurization tower provided by the utility model; Figure 2 For Figure 1 it is a schematic structural diagram of the three-dimensional left view of the device shown;

[0023] Figure 3 For Figure 1 it is a schematic structural diagram of the three-dimensional right view of the device shown. An anti-smoke-pollution noise-reducing desulfurization tower includes: a bottom plate 1, a desulfurization component 2 is arranged on the top of the bottom plate 1, and an auxiliary component 3 is arranged inside the desulfurization component 2;

[0024] The desulfurization assembly 2 includes a first desulfurization tower 21 disposed on the left side of the top of the bottom plate 1. A liquid inlet valve 22 is connected to the bottom on the left side of the first desulfurization tower 21. A second desulfurization tower 23 is disposed on the right side of the top of the bottom plate 1. A smoke outlet pipe 24 is disposed on the top on the right side of the first desulfurization tower 21, and the right side of the smoke outlet pipe 24 is communicated with the inside of the second desulfurization tower 23.

[0025] After the flue gas is desulfurized and purified by the first desulfurization tower 21, it will be discharged into the inside of the second desulfurization tower 23 along with the smoke outlet pipe 24, and then pass through the desulfurization of the second desulfurization tower 23 again, so that the flue gas is completely purified. Through the setting of the two desulfurization towers, the desulfurization effect of the flue gas is improved.

[0026] The auxiliary assembly 3 includes a partition plate 31 disposed at the bottom of the inner wall of the first desulfurization tower 21. A rotating rod 32 is rotatably disposed on the top of the partition plate 31. A scraping frame 33 is fixedly disposed on the circumferential side of the rotating rod 32, and the outer side of the scraping frame 33 is closely attached to the inner wall of the first desulfurization tower 21.

[0027] The auxiliary assembly 3 is also disposed inside the second desulfurization tower 23; when the rotating rod 32 rotates, it drives the scraping frame 33 to rotate. When the scraping frame 33 rotates, it will scrape the sediment on the inner wall of the first desulfurization tower 21, avoiding the corrosion of the inner wall of the desulfurization tower by the sediment.

[0028] A pump body 25 is disposed on the top of the bottom plate 1 and on the right side of the first desulfurization tower 21. The water inlet pipe on the left side of the pump body 25 is communicated with the inside of the first desulfurization tower 21, and a water outlet pipe 26 is disposed on the top of the pump body 25.

[0029] A first spray pipe 27 is disposed at the top of the inner wall of the first desulfurization tower 21. The right end of the first spray pipe 27 is communicated with the top of the water outlet pipe 26. A second spray pipe 28 is disposed at the top of the inner wall of the second desulfurization tower 23. The left end of the second spray pipe 28 is communicated with the right side of the water outlet pipe 26.

[0030] After the flue gas is discharged into the inside of the first desulfurization tower 21 through the smoke inlet 29, at this time, the pump body 25 works to drive the liquid at the bottom of the desulfurization tower to be sprayed into the flue gas through the first spray pipe 27 to complete the preliminary desulfurization. The flue gas after the preliminary reaction drifts into the inside of the second desulfurization tower 23 through the smoke outlet pipe 24. At the same time, the second spray pipe 28 works, so that the flue gas is fully mixed with the sprayed liquid, improving the desulfurization effect. Through the setting of the pump body 25, the liquid with still desulfurization effect is pumped out and reused, improving the use efficiency of the liquid medicine and reducing the desulfurization cost.

[0031] A smoke inlet 29 is disposed on the left side of the first desulfurization tower 21. An exhaust port 4 is disposed on the top of the second desulfurization tower 23. A drain valve 5 is disposed at the bottom of the second desulfurization tower 23.

[0032] The auxiliary component 3 further includes a fan blade 34 arranged at the top of the rotating rod 32. A reinforcing frame 35 is arranged at the top of the inner wall of the first desulfurization tower 21. The top of the rotating rod 32 is rotatably connected to the bottom of the reinforcing frame 35.

[0033] Through the arrangement of the fan blade 34, since the rotation of the rotating rod 32 will drive the low-speed rotation of the fan blade 34, when the fan blade 34 rotates at a low speed, it will blow the flue gas downward, thereby increasing the time of the flue gas inside the desulfurization tower, and further improving the desulfurization effect.

[0034] A driving motor 36 is arranged at the bottom of the inner wall of the first desulfurization tower 21 and below the partition plate 31. The output end at the top of the driving motor 36 penetrates the bottom of the partition plate 31 and extends to its top. The output end at the top of the driving motor 36 is fixedly connected to the bottom end of the rotating rod 32.

[0035] The working principle of an anti-flue gas pollution noise reduction desulfurization tower provided by the present utility model is as follows:

[0036] The first step: When in use, the rotation of the output end of the driving motor 36 drives the rotation of the rotating rod 32, and then drives the rotation of the fan blade 34 and the scraping frame 33. At this time, the flue gas enters the inside of the first desulfurization tower 21 through the smoke inlet 29. Under the action of the fan blade 34, the flue gas floats downward, thereby increasing the time of the flue gas staying inside the desulfurization tower. At the same time, the pump body 25 is used to suck out the liquid medicine and spray it out through the first spray pipe 27, so that the flue gas completes the preliminary desulfurization.

[0037] The second step: After the preliminary desulfurization is completed, the flue gas will enter the inside of the second desulfurization tower 23 along the smoke outlet pipe 24. After the second desulfurization tower 23 processes the flue gas again, the flue gas is discharged through the discharge port 4. Through the arrangement of the two desulfurization towers, the desulfurization effect of the flue gas is effectively improved. Through the arrangement of the pump body 25, the liquid medicine with remaining desulfurization effect is re-extracted and utilized, improving the utilization efficiency of the liquid medicine and reducing the desulfurization cost.

[0038] Compared with the related technology, an anti-flue gas pollution noise reduction desulfurization tower provided by the present utility model has the following beneficial effects:

[0039] Through the arrangement of the two desulfurization towers and the auxiliary component 3, the residence time of the flue gas inside the tower and the desulfurization effect are greatly improved, thereby improving the treatment efficiency of the flue gas. Through the arrangement of the pump body 25, the liquid medicine sprayed out with remaining desulfurization effect can be reused, reducing the desulfurization cost and improving the environmental protection.

[0040] Finally, it should be noted that the above embodiments are only relatively representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model shall be considered to fall within the protection scope of the present utility model.
