Abstract
Description
Technical Field
[0001] This application relates to the field of filtration and dust removal technology, and in particular to a wet dust collector. Background Technology
[0002] During long-term operation, wet scrubbers achieve gas-solid separation through gas-liquid contact, with the captured dust particles located in the lower chamber of the equipment. Under gravity, the particles gradually settle and accumulate at the bottom of the chamber, forming a sediment layer. Particularly noteworthy is the deposition of metal or mineral dust, which gradually hardens and adheres strongly to the inner wall of the chamber, ultimately forming a dense, firmly attached hard scale layer.
[0003] Currently, the removal of this type of scale mainly relies on manual cleaning operations during periodic shutdowns. Maintenance personnel need to enter confined spaces and use traditional methods such as mechanical impact and chisels to remove the scale. This method is not only labor-intensive and inefficient, but also fails to thoroughly remove scale layers in structural dead corners and tightly bonded areas, easily leaving cleaning residues and accelerating the next layer of compaction. Summary of the Invention
[0004] To facilitate cleaning of the bottom of the wet scrubber housing, this application provides a wet scrubber.
[0005] The wet dust collector provided in this application adopts the following technical solution: A wet scrubber includes a housing, a suction unit at the top of the housing, a filtrate stored at the bottom of the housing, an air inlet on the side wall of the housing, an air guide hood inside the housing, the top of the air guide hood connected to the air inlet, the bottom opening of the air guide hood inserted into the filtrate, multiple separation plates inside the housing, a circulating filtration assembly on the outer side of the bottom of the housing, a scraper slidably mounted on the bottom wall of the inner cavity of the housing, and a drive assembly at the bottom of the housing that drives the scraper to reciprocate within the housing.
[0006] By adopting the above technical solution, the suction component draws air into the chamber, allowing the dust-laden gas to first enter the air guide hood through the air inlet, and then enter the chamber through the filter liquid from the air guide hood. After the dust-laden gas enters the filter liquid, large dust particles will settle to the bottom of the chamber, while small dust particles will move towards the suction component with the water mist agitated by the filter liquid. The water mist will move to the separation plate and be adsorbed on the separation plate, thereby further eliminating dust. At the same time, the drive component drives the scraper to move back and forth at the bottom of the chamber, and the circulating filter component filters the dust in the filter liquid, making it less likely for the settled dust to form scale, thus facilitating the cleaning of the chamber by the staff.

[0014] By adopting the above technical solution, when the scraper moves towards the liquid outlet pipe, it scrapes up the dust settled at the bottom of the box and stores it in the second storage tank. When the scraper moves to abut against the inner wall of the box near the liquid outlet pipe, the side wall of the scraper and the inner wall of the box are attached to form a chamber around the second storage tank. At this time, the liquid outlet pipe is connected to the second storage tank. At the same time, the scraper drives the second trigger rod to move to abut against the inner wall of the box. The second trigger rod drives the second sealing block to rise through the lifting rod and the second push rod. The second sealing block moves to release the blockage of the liquid outlet. At this time, the filtrate in the second storage tank is blown into the first storage tank, thereby facilitating the filtration of dust in the box.
[0015] Preferably, the scraper has a connecting hole, and the two sides of the connecting hole are respectively connected to the first storage tank and the second storage tank. A filter screen is installed on the scraper inside the connecting hole.
[0016] By adopting the above technical solution, during the reciprocating movement of the scraper in the box, the connecting hole can connect the first storage tank and the second storage tank, so that when the scraper moves, the filtrate in the box can flow into the first storage tank or the second storage tank.

[0018] By adopting the above technical solution, when the filtrate in the first storage tank is sucked into the inlet pipe, the filtrate in the box is sucked into the first storage tank from the inlet. The filtrate drives the first rotating shaft to rotate through the first driving blade. The first rotating shaft drives the first driven blade to rotate. The first driven blade pushes the filtrate in the first connecting tank into the first storage tank, so that the dust is fully mixed in the filtrate, thereby facilitating the inlet pipe to suck in the dust in the filtrate.

The second driven blade pushes the filtrate in the second connecting tank into the second storage tank, so that the dust is fully mixed in the filtrate, thereby facilitating the dust in the filtrate to enter the outlet.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The circulating filter assembly and scraper, along with the suction unit, draw air into the chamber. The dust-laden gas first enters the air guide hood through the air inlet, and then passes through the air guide hood and into the chamber through the filtrate. After entering the filtrate, large dust particles settle to the bottom of the chamber, while small dust particles move towards the suction unit with the water mist agitated by the filtrate. The water mist is then adsorbed on the separation plate, further eliminating dust. At the same time, the drive assembly moves the scraper back and forth at the bottom of the chamber, and the circulating filter assembly filters the dust in the filtrate, making it less likely for the settled dust to form scale, thus facilitating cleaning of the chamber by the staff. 2.

At this time, the filtrate in the first storage tank is sucked into the liquid inlet pipe, which facilitates the filtration of dust in the box. 3. As the scraper moves towards the outlet pipe through the second storage tank, it scrapes up the dust settled at the bottom of the box and stores it in the second storage tank. When the scraper moves to abut the inner wall of the box near the outlet pipe, the side wall of the scraper and the inner wall of the box are attached to form a chamber around the second storage tank. At this time, the outlet pipe is connected to the second storage tank. At the same time, the scraper drives the second trigger rod to move and abut the inner wall of the box.

[0028] The following is in conjunction with the appendix Figures 1-11 This application will be described in further detail.
[0029] This application discloses a wet dust collector.
[0030] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A wet dust collector includes a housing 1, with an air outlet formed on the top of the housing 1. A suction component 2 is installed on the housing 1 at the air outlet. In this application, the suction component 2 can be a fan, and the suction component 2 can draw air into the interior of the housing 1 through the air outlet.
[0031] The bottom of the housing 1 stores filtrate. An air guide hood 4 is fixedly installed at the bottom of the inner cavity of the housing 1. The bottom of the air guide hood 4 is open and the bottom opening of the air guide hood 4 is submerged in the filtrate. An air inlet 3 is fixedly installed on the side wall of the housing 1. The air inlet 3 communicates with the inner cavity of the air guide hood 4 and is connected to the air intake pipe.
[0032] Water agitators 32 are fixedly installed on both opposite horizontal walls of the air guide shroud 4. The cross-section of the water agitator 32 is arc-shaped, and the middle part of the water agitator 32 protrudes away from the air guide shroud 4, with the middle part of the water agitator 32 located at the liquid surface of the filtrate. Inside the housing 1, multiple separation plates 5 are fixedly installed at intervals above the water agitators 32. Some of the separation plates 5 are installed at an angle, and some of the separation plates 5 are arc-shaped. The multiple separation plates 5 are installed alternately along the horizontal direction.
[0033] A support frame 34 is fixedly installed on the top of the inner cavity of the housing 1. Multiple mounting frames 35 are slidably installed inside the support frame 34, and each mounting frame 35 contains filter cotton, which is located below the air outlet. Multiple viewing windows 33 are rotatably installed on the side of the housing 1 away from the air inlet 3. The viewing windows 33 allow the staff to observe the internal operation of the housing 1. At the same time, opening the viewing windows 33 allows the mounting frames 35 to be slidably removed from the support frame 34, thus facilitating the replacement of the filter cotton.
[0034] After the suction unit 2 is activated, it draws air from inside the housing 1. The dust-laden gas enters the air guide hood 4 through the air inlet pipe and air inlet 3, and then enters the housing 1 through the filtrate. During the process of the dust-laden gas passing through the filtrate, large dust particles settle to the bottom of the housing 1 due to gravity. At the same time, the dust-laden gas causes the filtrate to oscillate, and the oscillating filtrate impacts the arc-shaped water agitator plate 32, which can more efficiently promote the generation of water mist. Small dust particles flow towards the suction unit 2 along with the water mist formed by the oscillation of the filtrate. When the water mist comes into contact with the separation plate 5, it will be adsorbed, achieving further purification of the dust. In addition, the filter cotton installed inside the housing can perform secondary adsorption of residual water mist and dust, which not only improves the overall dust removal efficiency, but also effectively reduces the loss of filtrate.
[0035] A circulating filter assembly 6 is installed on the outer side of the bottom of the housing 1. The circulating filter assembly 6 includes a water pump 61, a filter 62, an inlet pipe 63, an outlet pipe 64, and a connecting pipe 65. A base plate 36 is installed on the outer side of the bottom of the housing 1, and the filter 62 and the water pump 61 are both fixedly installed on the base plate 36. The two ends of the connecting pipe 65 are connected to the outlet end of the water pump 61 and the inlet end of the filter 62, respectively.
[0036] The inlet pipe 63 is installed on the inlet end of the water pump 61, and the end of the inlet pipe 63 away from the water pump 61 is connected to the inner cavity of the housing 1 through three connectors. The outlet pipe 64 is installed on the outlet end of the filter 62, and the end of the outlet pipe 64 away from the filter 62 is connected to the inner cavity of the housing 1 through three connectors. The inlet pipe 63 and the outlet pipe 64 are located on opposite sides of the housing 1.
[0037] During the dust removal process of the wet scrubber, the water pump 61 draws filtrate from the bottom of the housing 1 through the inlet pipe 63, and supplies it into the filter 62 via the inlet pipe 63, the water pump 61, and the connecting pipe 65. The filter 62 traps and separates the dust contained in the filtrate, and the purified filtrate returns to the inside of the housing 1 through the outlet pipe 64, thus forming a closed-loop filtrate circulation purification system. Continuous circulation can effectively reduce the solid concentration in the filtrate and reduce the risk of dust deposition and caking at the bottom of the housing 1.
[0038] The implementation principle of a wet dust collector according to an embodiment of this application is as follows: After the suction unit 2 is activated, it draws air from the inside of the housing 1. The dust-laden gas enters the air guide hood 4 through the air inlet pipe and air inlet 3, and then passes through the filter liquid into the inside of the housing 1. During the process of the dust-laden gas passing through the filter liquid, large dust particles settle to the bottom of the housing 1 due to gravity; at the same time, the dust-laden gas will cause the filter liquid to oscillate when passing through the filter liquid. The oscillating filter liquid impacts the arc-shaped water agitator plate 32, which can more efficiently promote the generation of water mist. Small dust particles flow towards the suction unit 2 along with the water mist formed by the oscillation of the filter liquid. When the water mist comes into contact with the separation plate 5, it will be adsorbed by it, and the dust will be further purified. During the dust filtration process, the water pump 61 draws the filter liquid from the bottom of the housing 1 through the liquid inlet pipe 63, and supplies it into the filter 62 through the liquid inlet pipe 63, the water pump 61 and the connecting pipe 65. The filter 62 intercepts and separates the dust contained in the filtrate, and the purified clean filtrate is returned to the inside of the housing 1 through the outlet pipe 64, which effectively reduces the solid concentration in the filtrate and reduces the risk of dust deposition and caking at the bottom of the housing 1.
[0039] Example 2: Reference Figure 4 , Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that a scraper 7 is reciprocally slidably installed at the bottom of the inner cavity of the box body 1 along the line connecting the inlet pipe 63 and the outlet pipe 64, and pressure plates 37 are fixedly installed on the opposite side walls of the box body 1 along the length of the scraper 7, with the two pressure plates 37 respectively abutting against the two ends of the top wall of the scraper 7 along the length of the scraper 7.
[0040] A drive assembly 8 is installed at the bottom of the housing 1. The drive assembly 8 includes a drive component 81, a drive shaft 82, two drive wheels 83, a transmission belt 84, and four pull ropes 85. The drive shaft 82 is rotatably mounted at the bottom of the housing 1, and the drive component 81 is fixedly mounted on the side wall of the bottom of the housing 1. The drive end of the drive component 81 is fixedly connected to the drive shaft 82. In this application, the drive component 81 can be a servo motor.
[0041] Two drive wheels 83 are fixedly mounted at both ends of the drive shaft 82. Two transmission belts 84 are rotatably mounted on both sides of the bottom of the housing 1 via multiple rollers, and the two transmission belts 84 mesh with the two drive wheels 83. Two pull ropes 85 are fixedly mounted at both ends of one transmission belt 84. The end of the pull rope 85 away from the transmission belt 84 passes through the side wall of the housing 1. The ends of the four pull ropes 85 are fixedly connected to the opposite side walls of the scraper 7, and the height of the pull rope 85 passing through the side wall of the housing 1 is greater than the liquid level of the filtrate.
[0042] The drive unit 81 moves by pulling four ropes 85 via the drive shaft 82 and the transmission belt 84. The four ropes 85 then pull the scraper 7 to move back and forth inside the housing 1. When the scraper 7 moves toward the liquid inlet pipe 63, it can scrape up the dust that has settled at the bottom of the inner cavity of the housing 1, thus making it easier for the liquid inlet pipe 63 to suck in the dust.
[0043] Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 Three first material storage troughs 9 are spaced apart on the side wall of the scraper 7 near the liquid inlet pipe 63, and the three first material storage troughs 9 correspond one-to-one with the three ends of the liquid inlet pipe 63. A first push rod 11 is installed inside the scraper 7 along its own length direction. The first push rod 11 is slidably installed inside the scraper 7 along the width direction of the scraper 7. A first trigger rod 10 is installed at both ends of the first push rod 11 near the side wall of the liquid inlet pipe 63. The end of the first trigger rod 10 away from the first push rod 11 slides out of the scraper 7.
[0044] The scraper 7 has three liquid inlets 13 at its top, which are connected to three first storage tanks 9. Three first sealing blocks 12 are fixedly installed on the side wall of the first push rod 11 near the first trigger rod 10. Multiple first elastic elements 14 are installed inside the scraper 7 on the side of the first push rod 11 away from the first trigger rod 10. In this application, the first elastic elements 14 can be springs. The first elastic elements 14 act on the first sealing blocks 12 through the first push rod 11, causing the three first sealing blocks 12 to slide and seal the three liquid inlets 13.
[0045] When the scraper 7 moves toward the inlet pipe 63, it scrapes up the dust settled at the bottom of the housing 1 and collects it into the first storage tank 9. When the scraper 7 moves to a position where it abuts against the inner wall of the housing 1 near the inlet pipe 63, the side wall of the scraper 7 fits tightly against the inner wall of the housing 1, so that the first storage tank 9 forms a chamber, and the chamber is connected to the inlet pipe 63. During the movement of the scraper 7, the first trigger rod 10 is moved simultaneously until the first trigger rod 10 abuts against the inner wall of the housing 1, and then the first push rod 11 drives the first sealing block 12 to move, releasing the blockage of the inlet 13.
[0046] At this time, the scraper 7 remains in contact with the inner wall of the housing 1, and the filtrate in the housing 1 enters the first storage tank 9 through the liquid inlet 13. The dust-laden filtrate in the first storage tank 9 can then be sucked into the liquid inlet pipe 63, which provides convenience for the subsequent dust filtration process.
[0047] Reference Figure 6 , Figure 7 , Figure 10 and Figure 11 Three second storage troughs 15 are spaced apart on the side wall of the scraper 7 near the liquid outlet pipe 64, and the three second storage troughs 15 correspond one-to-one with the three ends of the liquid outlet pipe 64. A second push rod 17 is installed inside the scraper 7 along its own length direction. The second push rod 17 is slidably installed inside the scraper 7 along the height direction of the scraper 7. Multiple lifting rods 18 are fixedly installed on the bottom wall of the second push rod 17.
[0048] Multiple second trigger rods 16 are slidably mounted horizontally on the side wall of the scraper 7 near the liquid outlet pipe 64, with the ends of the second trigger rods 16 extending out of the scraper 7. The number of second trigger rods 16 and lifting rods 18 are the same and correspond one-to-one. The ends of the second trigger rods 16 and lifting rods 18 that are close to each other are chamfered, and the chamfers at the ends of the second trigger rods 16 and lifting rods 18 fit together.
[0049] The scraper 7 has three liquid outlets 20 at its bottom, which are respectively connected to the three second storage tanks 15 and the first storage tank 9. Three second sealing blocks 19 are fixedly installed on the bottom wall of the second push rod 17. Multiple second elastic elements 21 are installed inside the scraper 7 at the top of the second push rod 17; in this application, the second elastic elements 21 can be springs. The second elastic elements 21 act on the second sealing blocks 19 through the second push rod 17, causing the three second sealing blocks 19 to slide and seal the three liquid outlets 20.
[0050] When the scraper 7 moves toward the outlet pipe 64, it scrapes up the dust settled at the bottom of the box 1 and collects it into the second storage tank 15. When the scraper 7 moves to a position where it abuts against the inner wall of the box 1 near the outlet pipe 64, the side wall of the scraper 7 fits tightly against the inner wall of the box 1, so that the second storage tank 15 forms a chamber, and this chamber is connected to the outlet pipe 64. During the movement of the scraper 7, the second trigger rod 16 is moved simultaneously until the second trigger rod 16 abuts against the inner wall of the box 1. The second trigger rod 16 drives the lifting rod 18 to rise through the chamfer. The lifting rod 18 then drives the second sealing block 19 to rise and move through the second push rod 17, thereby releasing the blockage of the outlet 20.
[0051] At this time, the scraper 7 remains in contact with the inner wall of the housing 1, and injects the clean filtrate in the outlet pipe 64 into the second storage tank 15, so that the filtrate containing dust in the second storage tank 15 enters the first storage tank 9 from the outlet 20, which facilitates the subsequent dust filtration process.
[0052] Reference Figure 7 and Figure 11 Two connecting holes 22 are provided on both sides of each liquid outlet 20 in the scraper 7, and both ends of each connecting hole 22 are connected to the first storage tank 9 and the second storage tank 15. A filter screen 23 is fixedly installed in each connecting hole 22 of the scraper 7.
[0053] During the reciprocating motion of the scraper 7 inside the housing 1, the connecting hole 22 allows for communication between the first storage tank 9 and the second storage tank 15, ensuring that the filtrate in the housing 1 can smoothly flow into either the first storage tank 9 or the second storage tank 15 when the scraper 7 moves. Simultaneously, the filter screen 23 built into the connecting hole 22 can intercept and filter dust in the filtrate, effectively preventing dust from flowing from the first storage tank 9 into the second storage tank 15.
[0054] Reference Figure 7 Two first connecting grooves 27 are formed on the side wall of the scraper 7, and the two ends of each first connecting groove 27 are respectively connected to two adjacent first storage troughs 9. A first rotating shaft 24 is rotatably mounted in the scraper 7 within the three first storage troughs 9 and the two first connecting grooves 27. Three first driving blades 25 are fixedly mounted on the first rotating shaft 24. The three first driving blades 25 are respectively located below the three liquid inlets 13, and a plurality of first driven blades 26 are fixedly mounted on the first rotating shaft 24 at intervals.
[0055] When the filtrate in the first storage tank 9 is drawn into the inlet pipe 63, the filtrate in the housing 1 is replenished into the first storage tank 9 through the inlet 13. During the flow of the filtrate, the first drive blade 25 is driven to rotate, which in turn drives the first rotating shaft 24 to rotate synchronously. The first rotating shaft 24 drives the first driven blade 26 to rotate. The first driven blade 26 stirs the filtrate in the first connecting tank 27 and the first storage tank 9 on the one hand, and drives the filtrate from the first connecting tank 27 into the first storage tank 9 on the other hand, so as to promote the thorough mixing of dust and filtrate, and ensure that the inlet pipe 63 can efficiently draw in the dust-laden filtrate.
[0056] Reference Figure 7 , Figure 10 and Figure 11 Two second connecting grooves 38 are formed on the side wall of the scraper 7, and the two ends of each second connecting groove 38 are respectively connected to two adjacent second storage troughs 15. A second rotating shaft 28 is rotatably mounted on the scraper 7 within the three second storage troughs 15 and the two second connecting grooves 38. Three second drive blades 29 are fixedly mounted on the second rotating shaft 28. The three second drive blades 29 are respectively located between the three liquid outlets 20 and the liquid outlet pipe 64, and multiple second driven blades 30 are fixedly mounted on the second rotating shaft 28 at intervals.
[0057] When the filtered clean filtrate is injected into the second storage tank 15 through the outlet pipe 64, it will drive the second drive blade 29 to drive the second rotating shaft 28 to rotate. The second rotating shaft 28 drives the second driven blade 30 to rotate. The second driven blade 30 stirs the filtrate in the second connecting tank 38 and the second storage tank 15 on the one hand, and drives the filtrate from the second connecting tank 38 into the second storage tank 15 on the other hand, so as to promote the dust and filtrate to be fully mixed, and ensure that the dust-containing filtrate can flow into the first storage tank 9 from the outlet 20.
[0058] The implementation principle of Embodiment 2 of this application is as follows: The driving component 81 moves by pulling four ropes 85 through the driving shaft 82 and the transmission belt 84. The four ropes 85 then pull the scraper 7 to move back and forth inside the housing 1. When the scraper 7 moves towards the liquid inlet pipe 63, it scrapes up the dust settled at the bottom of the housing 1 and collects it into the first storage tank 9. When the scraper 7 moves to a position where it abuts against the inner wall of the housing 1 near the liquid inlet pipe 63, the side wall of the scraper 7 fits tightly against the inner wall of the housing 1, so that the first storage tank 9 forms a chamber, and the chamber is connected to the liquid inlet pipe 63. During the movement of the scraper 7, the first trigger rod 10 is simultaneously displaced until the first trigger rod 10 abuts against the inner wall of the housing 1, and then the first push rod 11 drives the first sealing block 12 to move, thereby releasing the blockage of the liquid inlet 13. At this time, the scraper 7 remains in contact with the inner wall of the housing 1, and the filtrate in the housing 1 enters the first storage tank 9 through the liquid inlet 13. The dust-laden filtrate in the first storage tank 9 can then be sucked into the liquid inlet pipe 63, which provides convenience for the subsequent dust filtration process.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
