Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically a water film settling dust collector. Background Technology

[0002] In the process of industrial production and social operation, various combustion equipment, industrial kilns and production processes continuously generate a large amount of dust-laden flue gas. If this dust-laden flue gas is directly discharged into the atmosphere without effective treatment, the dust particles in it will not only seriously damage air quality and cause severe weather phenomena such as smog, but also have a profound impact on the ecological environment, harming the survival and reproduction of animals and plants, and seriously threatening human health. Long-term exposure to such an environment makes people very susceptible to respiratory diseases, lung diseases and other illnesses. In order to deal with the problem of dust-laden flue gas pollution, dust removal technology has emerged and continues to develop. As an important member of the dust removal technology field, water film settling dust collectors are gradually emerging. However, existing water film settling dust collectors still have some problems in use: First, the filter frames in existing water film dust collectors are mostly fixed, which makes it inconvenient to clean the settled sludge. At the same time, due to the lack of a dual filtration structure, the efficiency and purification effect of the dust collector are also affected to some extent. Secondly, existing water film dust collectors typically only have a single layer of spray heads. This structure has a limited coverage area during the dust removal process, which can easily lead to incomplete dust removal and make it difficult to meet the needs of high-efficiency purification.

[0016] 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.

[0017] Example: Figure 1-7As shown, this utility model provides a water film settling dust collector, including a base 1. A cylinder 6 and a water tank 8 are fixedly installed on the upper surface of the base 1. A sealing cover 7 is movably snapped onto the upper surface of the water tank 8, which can seal the water tank 8, reduce water evaporation in the water tank 8, and prevent external impurities from falling into the water tank 8 and contaminating the circulating water, thus ensuring the cleanliness of the spray water. A waste liquid discharge pipe 10 is connected to one side of the water tank 8. A control valve 9 is provided on the outer surface of the waste liquid discharge pipe 10. The control valve 9 can control the opening and closing of the waste liquid discharge pipe 10, which facilitates the periodic discharge of waste liquid in the water tank 8, avoids the accumulation of impurities affecting the water circulation efficiency, and is easy to operate. An air inlet pipe 4 is connected to one side of the cylinder 6, providing a channel for dust-laden gas to enter the cylinder 6. An exhaust pipe 5 is connected to the upper surface of the cylinder 6, which is used to discharge the purified gas. The two work together to form a gas flow path, ensuring that the dust-laden gas is discharged smoothly after completing the purification process inside the cylinder 6. A dust removal component 3 is provided on one side of the water tank 8 and inside the cylinder 6. The dust removal component 3 is responsible for forming a water film inside the cylinder 6 to remove dust. A sedimentation filter component 2 is provided between the water tank 8 and the cylinder 6. The sedimentation filter component 2 filters the dust-laden wastewater. The two work together to improve the overall dust removal efficiency and water recycling rate.

[0018] The sedimentation filtration assembly 2 includes a filter box 21, which is fixedly installed on the upper surface of the water tank 8. A support plate 22 is fixedly connected to the upper surface of the base 1 in parallel. The filter box 21 is fixedly installed on the upper surface of the support plate 22. The support plate 22 provides additional support for the filter box 21 and enhances the stability of the filter box 21 installation. A drain pipe 24 is connected to the upper surface of the filter box 21, and the top end of the drain pipe 24 is connected to the lower surface of the cylinder 6. The drain pipe 24 can guide the wastewater containing dust captured in the cylinder 6 into the filter box 21 for filtration, realizing centralized treatment of wastewater and laying the foundation for water recycling.

[0019] The filter box 21 has a filter frame 23 that is movably snapped into the inner cavity to work with the drain pipe 24. The filter frame 23 can perform initial filtration of the sewage flowing in from the drain pipe 24, intercepting larger dust particles. The movable snap-fit ​​installation method facilitates disassembly, cleaning, or replacement, ensuring stable filtration effect. The upper surface of the filter box 21 is symmetrically fixedly connected with vertical plates 25. One side of the vertical plates 25 is rotatably connected to a limiting stop bar 26 that works with the filter frame 23 via a rotating shaft. Rotating the limiting stop bar 26 can limit and fix the filter frame 23, preventing the filter frame 23 from shaking or shifting when the sewage flows in the filter box 21. The damping rotation design ensures that the limiting stop bar 26 can be stably kept in the limited position, while also facilitating operation.

[0020] The filter box 21 is connected to a water outlet pipe 27 on one side. The water outlet pipe 27 leads the filtered water in the filter box 21 to the water tank 8 for reuse. The outer surface of the water outlet pipe 27 is threaded with a filter cover 28. The filter cover 28 can perform secondary filtration on the water to further remove fine impurities. The threaded connection makes it easy to disassemble and clean the filter components inside the filter cover 28. The dual filtration structure improves the water purification effect.

[0021] The dust removal component 3 includes a water pump 32, which is fixedly installed on the upper surface of the base 1. The water inlet of the water pump 32 is connected to a water suction pipe 33, and the side of the water suction pipe 33 away from the water pump 32 is connected to the side of the water tank 8. The water pump 32 draws clean water from the water tank 8 through the water suction pipe 33 to provide power for the spraying, ensuring that the water flow can be smoothly delivered to the spraying structure inside the cylinder 6, and ensuring the water pressure and water volume required for the formation of the water film. The end of the water suction pipe 33 is also equipped with a filter screen to prevent sludge from entering the water pump 32.

[0022] The outlet end of the water pump 32 is connected to a connecting pipe 31, and the end of the connecting pipe 31 away from the water pump 32 passes through the cylinder 6 and is respectively connected to a first diversion pipe 39, a second diversion pipe 301, and a third diversion pipe 302. The connecting pipe 31 distributes the water transported by the water pump 32 to the first diversion pipe 39, the second diversion pipe 301, and the third diversion pipe 302, realizing the layered transport of water flow and providing a basis for multi-layer spraying. The ends of the first diversion pipe 39, the second diversion pipe 301, and the third diversion pipe 302 are respectively connected to a first diversion ring pipe 306, a second diversion ring pipe 304, and a third diversion ring pipe 35. The first diversion ring pipe 306, the second diversion ring pipe 304, and the third diversion ring pipe 35 can disperse the water transported by each diversion pipe to the annular area, so that the water flow can be evenly distributed to each spray head, ensuring the uniformity of spraying.

[0023] A first positioning rod 38, a second positioning rod 37, and a third positioning rod 36 are fixedly connected to one side of the first diversion ring pipe 306, the second diversion ring pipe 304, and the third diversion ring pipe 35, respectively. The ends of the first positioning rod 38, the second positioning rod 37, and the third positioning rod 36 are all fixedly connected to the inner wall of the cylinder 6. The first positioning rod 38, the second positioning rod 37, and the third positioning rod 36 fix the first diversion ring pipe 306, the second diversion ring pipe 304, and the third diversion ring pipe 35 to the inner wall of the cylinder 6, ensuring that each diversion ring pipe remains stable under water pressure and airflow impact, and avoiding positional displacement that affects the spraying effect.

[0024] Furthermore, the lower surfaces of the first diversion ring pipe 306, the second diversion ring pipe 304, and the third diversion ring pipe 35 are respectively connected in a ring array with a first spray head 305, a second spray head 303, and a third spray head 34. The first spray head 305, the second spray head 303, and the third spray head 34 are arranged in a ring array and layered, which can expand the spray range, form a more comprehensive and uniform water film inside the cylinder 6, improve dust capture efficiency, and achieve efficient dust removal.

[0025] Working principle: First, the dust-laden gas enters the cylinder 6 through the air inlet pipe 4. At this time, the dust removal component 3 is started, and the water pump 32 draws clean water from the water tank 8 through the water pumping pipe 33. The clean water is transported through the connecting pipe 31 to the first diversion pipe 39, the second diversion pipe 301 and the third diversion pipe 302, and then flows into the first diversion ring pipe 306, the second diversion ring pipe 304 and the third diversion ring pipe 35 respectively.

[0026] Since the first diversion ring pipe 306, the second diversion ring pipe 304 and the third diversion ring pipe 35 are fixed to the inner wall of the cylinder 6 by the first positioning rod 38, the second positioning rod 37 and the third positioning rod 36, their positions are stable, ensuring that the first spray head 305, the second spray head 303 and the third spray head 34 can form a layered and annularly distributed spray area inside the cylinder 6.

[0027] The sprayed water forms a continuous water film on the inner wall of the cylinder 6. When the dust-laden gas flows inside the cylinder 6, the dust particles are captured by the water film due to inertia, centrifugal force, etc., thus achieving gas-dust separation. The purified gas is discharged through the exhaust pipe 5.

[0028] During the dust removal process, the wastewater carrying dust flows down the inner wall of the cylinder 6 and enters the filter box 21 in the settling filter assembly 2 through the drain pipe 24. The filter box 21 is stably supported by the support plate 22. The wastewater first passes through the filter frame 23 for initial filtration, and larger dust particles are intercepted. The filter frame 23 is fixed by the limiting bar 26 on the vertical plate 25 to prevent it from shifting under the impact of water flow.

[0029] After the initial filtration, the wastewater flows out through the outlet pipe 27 and undergoes secondary filtration through the filter cover 28 to further remove fine impurities. The purified water then flows back into the water tank 8, realizing the recycling of water resources.

[0030] The sealing cover 7 on the water tank 8 can reduce water evaporation and impurities entering, ensuring the cleanliness of the circulating water.

[0031] When a certain amount of sludge or waste liquid accumulates in the water tank 8, the waste liquid can be discharged through the waste liquid discharge pipe 10 by opening the control valve 9, thus maintaining the normal operation of the water tank 8.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
