[0004] However, existing wet scrubbers can only capture larger dust particles, and cannot effectively remove smaller diameter particles in dust and flue gas, thus resulting in incomplete dust removal. Utility Model Content

[0032] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0033] like Figures 1-3 The diagram shown is a schematic of the water film dust collector of this utility model. The dust collector includes a base frame 1, a support frame 2, a dust collection box 3, a water collection tank 4, a vortex assembly, an overflow assembly, a water-blocking assembly, and a noise reduction assembly. The base frame 1 mainly serves a supporting function and is fixed to the ground by bolts. The support frame 2 is fixed to the top of the base frame 1 by welding. The support frame 2 is used to fix the dust collection box 3 and the water collection tank 4.

[0034] The dust removal box 3 is fixed on the top of the support frame 2 by screwing, the water collecting box 4 is fixed on the bottom of the dust removal box 3 by screwing and nut cooperation, and is connected with the inside of the dust removal box 3. The support frame 2 is arranged to support the dust removal box 3 away from the ground, so as to provide a space for the installation of the water collecting box 4.

[0035] The water collecting box 4 is funnel-shaped, that is, one side is large and the other side is small. In actual fixing, the large side of the water collecting box 4 is fixed on the bottom of the dust removal box 3, and the small side of the water collecting box 4 faces the ground, so as to facilitate the discharge of sewage after long-time dust removal. The butterfly valve 5 is fixed on the bottom of the water collecting box 4, and is in a closed state during dust removal, so as to avoid water leakage in the water collecting box 4. After long-time dust removal, the butterfly valve 5 is opened, and the sewage in the water collecting box 4 can be discharged.

[0036] The air inlet 6 is fixed on one side of the top of the dust removal box 3, and the gas to be removed is introduced from the air inlet 6. The first flow guide plate 7 is fixed on the inner side wall of the dust removal box 3 by welding and is connected with the air inlet 6, as shown in Figure 1 , the first flow guide plate 7 is arranged obliquely (that is, the high side of the first flow guide plate 7 is close to the air inlet 6), which is used for guiding the introduced gas to flow more smoothly to the vortex assembly.

[0037] The vortex assembly is fixed on the inner side wall of the dust removal box 3, which is used for dust removal of the introduced gas, as shown in Figure 3 , 4 , the vortex assembly includes upper blades, lower blades and a vortex throat 15. The upper blades and the lower blades are fixed on the inner side wall of the dust removal box 3 by welding and are arranged above and below, and a gap is left between the upper blades and the lower blades. The vortex throat 15 is in "S" shape and is formed between the upper blades and the lower blades.

[0038] The working principle is as follows: when the dust-containing gas enters the dust removal box 3 from the air inlet 6, under the guiding action of the first flow guide plate 7, the airflow will impact on the water surface of the dust removal box 3, and part of the larger particles will fall into the water. Then the gas in the dust removal box 3 will pass through the S-shaped vortex throat 15 formed by the upper blades and the lower blades. When passing through the vortex throat 15, a large amount of water splashes will be generated, so that the water and gas are fully contacted, and most of the fine dust particles are mixed into the water. At the same time, the vortex throat 15 changes the whole flow direction, generates the necessary relative motion of particles and droplets, and forms an effective dust removal process.

[0039] As shown in Figure 4As shown, the upper blade includes a second guide plate 8, a transition plate 9, a backflow plate 10 and a reinforcing plate 11. The second guide plate 8 is fixed to the inner side wall of the dust removal tank 3 and is arranged obliquely. The oblique direction of the second guide plate 8 is opposite to that of the first guide plate 7 (i.e. the highest point of the second guide plate 8 is connected to the lowest point of the first guide plate 7). The dust-containing gas is introduced from the air inlet 6 and guided by the first guide plate 7 and the second guide plate 8 in sequence, so as to ensure that the dust-containing gas impacts downward on the water surface in the dust removal tank 3 and is preliminarily dedusted.

[0040] The transition plate 9 is integrally connected to the bottom of the second guide plate 8. The transition plate 9 is arc-shaped, and the center of the arc faces the side of the second guide plate 8 away from the first guide plate 7. The backflow plate 10 is integrally connected to the side of the transition plate 9 away from the second guide plate 8. The backflow plate 10 is also arc-shaped, and the arc faces away from the second guide plate 8. By arranging the transition plate 9 and the backflow plate 10, a vortex throat 15 is formed below them. The reinforcing plate 11 is fixed between the second guide plate 8 and the backflow plate 10, so as to improve the structural strength of the backflow plate 10 and avoid the backflow plate 10 from swinging when the dust-containing gas passes through the vortex throat 15, thereby avoiding the gas from flowing back.

[0041] The lower blade includes a baffle plate 12, a vortex plate 13 and a third guide plate 14. The baffle plate 12 is fixed to the inner side wall of the dust removal tank 3. The vortex plate 13 is integrally connected to the top of the baffle plate 12. The baffle plate 12 is used to support the vortex plate 13. The vortex plate 13 is arc-shaped, and the center of the arc faces the upper blade. The third guide plate 14 is integrally connected to the side of the vortex plate 13 away from the baffle plate 12 and is arranged obliquely.

[0042] An overflow assembly is arranged on one side of the dust removal tank 3 and cooperates with the vortex assembly to dedust the dust-containing gas. As shown, Figure 5 The overflow assembly includes a water overflow tank 16, a partition plate 17, an overflow chamber 18, a sealing chamber 19, a communication pipe 20, an overflow pipe 21, a drainage pipe 22 and an atmosphere pipe 23. The water overflow tank 16 is fixed to one side of the support frame 2 by welding. The partition plate 17 is fixed to the inner side of the water overflow tank 16, so as to divide the water overflow tank 16 into the overflow chamber 18 above and the sealing chamber 19 below.

[0043] The overflow pipe 21 is fixed to the partition plate 17. The upper part of the overflow pipe 21 extends into the overflow chamber 18, and the lower part of the overflow pipe 21 extends into the sealing chamber 19. Therefore, the overflow chamber 18 and the sealing chamber 19 are communicated through the overflow pipe 21.

[0044] The communication pipe 20 is obliquely fixed in the water collecting tank 4 and communicates with the overflow tank 16 (specifically, the communication pipe 20 is obliquely arranged, and the high part of the communication pipe 20 communicates with the overflow chamber 18 of the overflow tank 16). By arranging the communication pipe 20, the water surface in the dust removal tank 3 is ensured to be between the vortex throat 15, avoiding the situation that the dust-containing gas cannot pass through the vortex throat 15 due to the blockage of the vortex throat 15 or cannot be dusted due to being far away from the vortex throat 15.

[0045] The upper surface of the overflow pipe 21 is located between the vortex throat 15, so as to ensure that the water surface in the dust removal tank 3 is between the vortex throat 15. By arranging the overflow pipe 21, when water is injected into the water collecting tank 4, the water surface can be prevented from being higher than the vortex throat 15.

[0046] The drain pipe 22 is connected to one side of the sealing chamber 19, and the drain pipe 22 is higher than the lower surface of the overflow pipe 21, thereby playing a sealing role, avoiding the external air entering the dust removal tank 3 and affecting the dust removal of the dust-containing gas; and by arranging the drain pipe 22, the water injection amount in the water collecting tank 4 can also be directly understood. The atmosphere pipe 23 is connected to the top of the overflow chamber 18, ensuring the constancy of the internal and external air pressure, facilitating the circulation of water flow.

[0047] The butterfly valve 5 is closed, the operator injects water into the water collecting tank 4, and the water surface in the water collecting tank 4 gradually rises. Since the communication pipe 20 connects the water collecting tank 4 and the overflow chamber 18, part of the water will enter the communication pipe 20. After continuing to inject water, the water surface in the water collecting tank 4 will rise to a position where the upper surface of the overflow pipe 21 is flush (at this time, the water surface is just between the vortex throat 15).

[0048] Then continue to inject water. Since the overflow pipe 21 connects the overflow chamber 18 and the sealing chamber 19, the water surface in the water collecting tank 4 will not rise when the water is continuously injected, and the excess water will flow to the sealing chamber 19 through the overflow pipe 21 until the water flows out from the drain pipe 22 on one side of the sealing chamber 19 (when the water flows out from the drain pipe 22 on one side of the sealing chamber 19, the injection of water can be stopped). At this time, it is indicated that the water surface in the water collecting tank 4 is just between the vortex throat 15, and a part of water is stored in the sealing chamber 19. Since the drain pipe 22 is higher than the lower surface of the overflow pipe 21, the water in the sealing chamber 19 can just play a sealing role, avoiding the external air entering the dust removal tank 3 through the drain pipe 22 and the overflow pipe 21. At the same time, a part of water is also stored in the overflow chamber 18, avoiding the external air entering the dust removal tank 3 through the atmosphere pipe 23.

[0049] The water blocking assembly is fixed to the inner side wall of the dust removal tank 3 and is located on the side of the first flow guide plate 7 away from the air inlet 6, and performs water removal treatment on the purified gas, avoiding the water in the dust removal tank 3 from being taken out, such as Figure 3 、 6As shown, the water blocking assembly includes a water blocking plate 24, a water collecting strip 25, a fixing plate 26 and a hook 27. The fixing plate 26 is fixed on the inner side wall of the dust removal box 3 by screwing or welding, and a plurality of holes are arranged on the opposite side of the fixing plate 26 for fixing the water blocking plate 24.

[0050] The water blocking plate 24 is connected end to end and arranged in cross to change the flow direction of the purified gas (a "V" shape is formed between the two adjacent water blocking plates 24). The hook 27 is integrally connected to the outermost side of the water blocking plate 24. In actual assembly, the hook 27 on one side of the water blocking plate 24 is hung in the hole of one of the fixing plates 26, and then the hook 27 on the other side is hung in the hole of the other fixing plate 26 (since the water blocking plate 24 is connected end to end and arranged in cross, the water blocking plate 24 forms a bent sheet structure between the water blocking plates 24, and therefore has a certain elasticity, which will not affect the normal installation).

[0051] The water collecting strip 25 is connected between the two adjacent water blocking plates 24, and the openings of the water collecting strips 25 face opposite directions. After the dust-containing gas is removed by the vortex assembly, the purified gas is discharged from the air outlet 28 at the top of the dust removal box 3 through the water blocking assembly. At this time, the purified gas changes the path through the water blocking plate 24, and after contacting the water collecting strip 25, the water vapor will gradually condense on the surface of the water collecting strip 25, and will fall back into the dust removal box 3 under the action of gravity.

[0052] The fan 29 is connected to the air outlet 28, and under the rotation of the fan 29, the purified gas in the dust removal chamber is extracted. The sound attenuation assembly is installed on one side of the fan 29 to reduce noise. As shown, Figure 7 The sound attenuation assembly includes a sound attenuation bin 30, an outer asbestos plate 31, an inner asbestos plate 32, a first tapered portion 33 and a second tapered portion 34. The sound attenuation bin 30 is fixed on the air outlet of the fan 29 by flange connection, and the outer asbestos plate 31 is fixed on the inner side wall of the sound attenuation bin 30 to attenuate the gas discharged by the fan 29.

[0053] The inner asbestos plate 32 is fixed on the inner side of the sound attenuation bin 30, and the first tapered portion 33 and the second tapered portion 34 are arranged on the upper and lower sides of the inner asbestos plate 32, respectively. When the gas enters the sound attenuation bin 30, the first tapered portion 33 of the inner asbestos plate 32 will separate the gas, so that the sound attenuation of the gas is completed under the joint action of the outer asbestos plate 31 and the inner asbestos plate 32.

[0054] By arranging the tapered portions on the upper and lower sides of the inner asbestos plate 32, the installation efficiency can be improved without distinguishing the front and back.

[0055] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
