Abstract

The application relates to a double-tower water dust collector, belonging to the technical field of industrial dust removal, which comprises a dust suction mechanism, a spraying mechanism and a water tank. The dust suction mechanism is composed of a first supporting tower and a second supporting tower which are connected through a connecting pipe to form a double-tower structure, a dust suction pipe is arranged on the side wall of the first supporting tower to introduce dust-containing waste gas, an air extractor is arranged on the top of the second supporting tower to provide negative pressure power, and a filter assembly is arranged in the tower. The spraying mechanism sends water in the water tank to main spraying assemblies and secondary spraying assemblies through a water pump, and sprays the water into the first supporting tower and the connecting pipe. After the dust-containing waste gas enters the system, the spraying water sprayed by the main spraying assemblies is used to wet the dust-containing waste gas, and the wetting is intensified through a turbine fan to make the dust lose the dry and loose characteristics, and the dust is bonded into a group or wrapped in water drops. The core of the application is that the wet state of the captured dust is maintained throughout the process, and the wet dust is directly sent back to the water, so that the secondary dust raising problem caused by the dry dust treatment in the traditional dry dust removal process is fundamentally eliminated.

Description

Technical Field

[0001] This application relates to the technical field of industrial dust removal, and in particular to a dual-tower water dust collector. Background Technology

[0002] Industrial waste gas treatment technology has developed rapidly in recent years. With increasingly stringent environmental regulations, enterprises have significantly increased their demand for efficient and reliable dust removal equipment.

[0003] Commonly used dust removal methods in the market are electrostatic precipitators and bag filters. Electrostatic precipitators use a high-voltage electric field to charge dust particles, which are then adsorbed onto the collecting electrode. Bag filters collect dust particles through filter bags. Both methods collect dry, loose dust. The core problem lies in the mechanical force or airflow impact applied during dust removal (such as rapping or pulse jet cleaning) and dust conveying or discharging. This force can easily cause dry dust to detach from the collecting surface and be re-entrained, creating secondary dust. Secondary dust escape not only reduces dust removal efficiency but also severely pollutes the workshop environment, impacting health and safety. Utility Model Content

[0004] To prevent the collected dust from escaping and polluting the workshop environment, thereby affecting the health and safety of production operators, this application provides a dual-tower water dust collector.

[0005] The dual-tower water dust collector provided in this application adopts the following technical solution: A dual-tower water dust collector includes a spraying mechanism and a water tank; a first support tower, a connecting pipe, a second support tower, and an exhaust fan; both the first and second support towers are connected to and communicate with the water tank; a suction pipe is connected to the side wall of the first support tower; the connecting pipe is located between and communicates with both the first and second support towers; the exhaust fan is connected to the upper end of the second support tower; the spraying mechanism includes a water pump, a spraying support pipe, a main spraying assembly, and a secondary spraying assembly; both the water pump and the spraying support pipe are connected to the water tank; the water pump is used to transfer water from the water tank to the spraying support pipe; both the main spraying assembly and the secondary spraying assembly are connected to the spraying support pipe; the main spraying assembly extends into the first support tower; and the secondary spraying assembly extends into the connecting pipe.

[0006] By adopting the above technical solution, dust-laden exhaust gas enters the first support tower through the suction pipe. Coarse dust particles settle directly into the water in the water tank through the first connecting hopper due to gravity. The main spray assembly sprays water onto the first support tower to capture the dust. The secondary spray assembly sprays water a second time inside the connecting pipe to enhance water-dust mixing. The exhaust fan drives the airflow sequentially through the first support tower and the connecting pipe to the second support tower, forming a negative pressure suction force. The water tank provides the spray water source and collects the settled dust.

[0007] Preferably, the main spray assembly includes a first spray pipe and a second spray pipe. One end of the first spray pipe is connected to a spray support pipe, and the other end of the first spray pipe extends into a first support tower. The second spray pipe is located inside the first support tower and is connected to and communicates with the first spray pipe. Both the first and second spray pipes are equipped with spray heads.

[0008] By adopting the above technical solution, the first spray pipe and the second spray pipe form a three-dimensional spray network, covering the cross-section of the first support tower, ensuring that the dust-laden airflow fully contacts the water. Multiple spray heads are evenly distributed on the first spray pipe and the second spray pipe. After large dust particles are captured by the water flow, they settle into the water tank through the first connecting bucket.

[0009] Preferably, a dispersing block is fixedly connected to the nozzle of the spray head, the dispersing block being used to break and disperse the concentrated water flow sprayed from the spray head into fine droplets or highly turbulent water flow; the main spray assembly also includes a turbine fan, the turbine fan being connected inside the first support tower; the turbine fan is used to accelerate the mixing of water and dust.

[0010] By adopting the above technical solution, the dispersion block is a tapered conical spiral structure, which is used to break the concentrated water flow into fine droplets, increase the water-dust contact area, and improve the fine dust capture rate. The turbine fan is driven to rotate naturally by the airflow, which enhances the turbulence inside the tower, forces the water and dust to mix, and prevents dust from escaping.

[0011] Preferably, the secondary spray assembly includes a third spray pipe and a dispersion plate. One end of the third spray pipe is connected to the spray support pipe, and the other end of the third spray pipe extends into the connecting pipe. The third spray pipe extending into the connecting pipe has a spray nozzle. The dispersion plate is connected into the connecting pipe, and the spray nozzle on the third spray pipe faces the dispersion plate. The dispersion plate is used to disperse the water sprayed from the spray nozzle.

[0012] By adopting the above technical solution, the spray nozzle of the third spray pipe directs the water flow to the dispersion plate, and the impact of the water flow forms a water mist curtain that covers the cross section of the connecting pipe, thereby providing secondary humidification for suspended fine dust.

[0013] Preferably, a dual-tower water dust collector further includes a filter assembly, which includes a support plate, a support cylinder, a retaining ring, a connecting piece, and a baffle. The support plate is connected inside a second support tower, the lower end of the support cylinder is connected to the support plate, the retaining ring is flared with a narrower top and a wider bottom, the upper end of the retaining ring is connected to the upper end of the support cylinder, and the lower end of the retaining ring seals against the inner wall of the second support tower. The connecting piece connects the baffle to the support cylinder, and the baffle is a conical cover with the apex pointing upwards, the lower diameter of the conical cover being larger than the upper diameter of the retaining ring.

[0014] By adopting the above technical solution, the baffle is a conical structure, which slows down the airflow and intercepts large dust particles; the flared slope of the baffle ring forms an annular channel with the baffle, the airflow is guided to generate swirling flow, and fine particles collide with the slope under the action of centrifugal force and settle into the water tank; the support cylinder and connecting plate are used to fix the baffle, the purified airflow is discharged from the upper end of the support cylinder and between the baffle, and the intercepted dust returns to the water tank through the second connecting hopper.

[0015] Preferably, a third observation window is connected to the side wall of the second support tower for observing the internal filter assembly. A third clamping member is also connected to the side wall of the second support tower for pressing the third observation window against the side wall of the second support tower.

[0016] By adopting the above technical solution, the third observation window is made of transparent material, which facilitates real-time monitoring of the filter component blockage; the observation window is tightened by the cooperation of the tightening wrench and the connecting lock to ensure the airtightness of the dust removal process.

[0017] Preferably, a dual-tower water dust collector further includes a dust scraping mechanism, which includes a transmission assembly and a support assembly; the support assembly includes a connecting box and a dust outlet box, the upper end of the connecting box is inclined away from the water tank, the lower end of the connecting box is connected to and communicates with the water tank; and the upper end of the dust outlet box is connected to and communicates with the connecting box, and the lower end of the dust outlet box has a dust outlet; the transmission assembly is used to scrape the dust settled on the bottom wall of the water tank along the bottom wall of the water tank to the bottom wall of the connecting box, and continue to scrape it to the connection port between the dust outlet box and the connecting box.

[0018] By adopting the above technical solution, the dust scraper moves along the bottom wall of the water tank and the connecting box via chain drive, scraping the settled dust from the water tank through the inclined connecting box to the dust outlet box, thus achieving automatic sludge removal; the inclined design of the connecting box allows the water carried away by the scraper to flow back to the water tank, reducing water loss.

[0019] Preferably, the transmission assembly includes a first support shaft, a second support shaft, a third support shaft, dust scrapers, a chain, and a dust scraper motor; the first and second support shafts are connected inside the water tank; the third support shaft is connected to the connecting box; each of the first, second, and third support shafts is equipped with a sprocket, the chain is hooked onto the sprockets on the first, second, and third support shafts, multiple dust scrapers are arranged along the length of the chain, and the lower ends of the dust scrapers abut against the bottom wall of the water tank and the bottom wall of the connecting box; the dust scraper motor is connected to the support assembly, and the dust scraper motor is used to drive the third support shaft to rotate.

[0020] By adopting the above technical solution, the dust scraper motor drives the third support shaft to rotate through the reducer. The third support shaft then drives the chain through the meshing of the sprocket. The chain then drives the dust scraper plate to move through the mounting plate. The dust scraper plate scrapes the dust that has settled on the bottom wall of the water tank along the bottom wall of the water tank and the bottom wall of the connecting box to the connection port between the dust outlet box and the connecting box. Then the dust falls down from the top of the dust outlet box and is finally discharged from the dust outlet.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. After dust-laden exhaust gas enters the system, it is immediately moistened by the spray water from the main spray assembly, and the mixing is enhanced by a turbine fan, causing the dust to lose its dry and loose properties, agglomerating into clumps or being encased in water droplets. The core principle is to maintain the captured dust in a moist state throughout the entire process and directly return the moist dust to the water, fundamentally eliminating the secondary dust generation problem caused by handling dry dust in the "dust removal" stage of traditional dry dust removal methods.

[0022] 2. The dust scraper moves along the bottom wall of the water tank and the connecting box via chain drive, scraping the settled dust from the water tank through the inclined connecting box to the dust outlet box, thus achieving automatic sludge removal; the inclined design of the connecting box allows the water carried away by the scraper to flow back to the water tank, reducing water loss.

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0039] This application discloses a dual-tower water dust collector, referring to... Figure 1 and Figure 3 The system includes a dust collection mechanism 1, a spraying mechanism 2, a dust scraping mechanism 3, a control box 4, and a water tank 5. The dust collection mechanism 1 is installed on the water tank 5 and is used to draw industrial waste gas into the dual-tower water dust collector. The spraying mechanism 2 is partially installed on the dust collection mechanism 1 and partially on the water tank 5. The spraying mechanism 2 is used to spray the dust drawn into the dual-tower water dust collector. The dust scraping mechanism 3 is partially installed outside the water tank 5 and partially inside the water tank 5. After being sprayed by the spraying mechanism 2, the dust falls onto the water surface in the water tank 5 and then sinks to the bottom wall of the water tank 5. The dust is then scraped off from the dual-tower water dust collector by the dust scraping mechanism 3. The control box 4 is installed on one side wall of the water tank 5 and is used to centrally control the operation of the dust collection mechanism 1, the spraying mechanism 2, and the dust scraping mechanism 3.

[0040] Reference Figures 1-3 The vacuuming mechanism 1 includes a first support tower 11, a first connecting bucket 12, a connecting pipe 13, a support box 14, a second support tower 15, a filter assembly 17, an exhaust fan 18, and a second connecting bucket 19. The first connecting bucket 12 is vertically arranged, and the upper diameter of the first connecting bucket 12 is larger than the lower diameter. The upper end of the first connecting bucket 12 is fixedly connected to the upper top wall of the water tank 5, and the lower end of the first connecting bucket 12 is located inside the water tank 5. The first support tower 11 is vertically arranged, and the lower end of the first support tower 11 is fixedly connected to the upper end of the first connecting bucket 12. A vacuuming pipe 111 is also fixedly connected to the side wall of the first support tower 11. The vacuuming pipe 111 communicates with the first support tower 11, the first support tower 11 communicates with the first connecting bucket 12, and the first connecting bucket 12 communicates with the water tank 5. The second support tower 15 is located on one side of the first support tower 11. The second support tower 15 is vertically arranged. The lower end of the second support tower 15 is fixedly connected to the upper top wall of the water tank 5. The lower end of the second support tower 15 is connected to the water tank 5. The exhaust fan 18 is fixedly connected to the upper end of the second support tower 15.

[0041] Reference Figure 3 The second connecting bucket 19 is vertically arranged and fixedly connected inside the second support tower 15. The upper diameter of the second connecting bucket 19 is larger than the lower diameter. An extension pipe 191 is fixedly connected to the lower end of the second connecting bucket 19, and the lower end of the extension pipe 191 extends into the water tank 5.

[0042] Reference Figure 1 , Figure 3 and Figure 4The vacuuming mechanism 1 also includes a connecting plate 16, the lower bottom wall of which is fixedly connected to the upper end of the second connecting hopper 19, and the length direction of the connecting plate 16 is perpendicular to the axis of the second connecting hopper 19. The filter assembly 17 is located inside the second support tower 15. The filter assembly 17 includes a support plate 171, a support cylinder 172, a retaining ring 173, a connecting piece 174, and a baffle 175. The lower bottom wall of the support plate 171 is fixedly connected to the upper top wall of the connecting plate 16. The support cylinder 172 is vertically arranged, and its lower end is fixedly connected to the upper top wall of the support plate 171. The retaining ring 173 is vertically arranged and has an flared shape that is narrower at the top and wider at the bottom. The side wall of the retaining ring 173 is an outwardly inclined surface from the top to the bottom. The upper end of the retaining ring 173 is fixedly connected to... At the upper end of the support cylinder 172, the lower end of the retaining ring 173 abuts against the inner circumferential side wall of the second support tower 15. Connecting pieces 174 are vertically arranged, and multiple connecting pieces 174 are provided. The lower ends of the multiple connecting pieces 174 are fixedly connected to the top of the support cylinder 172 and are circumferentially distributed around the axis of the support cylinder 172. The baffle 175 is a conical hood, vertically arranged with the cone apex facing upwards. The baffle 175 is fixedly connected to the upper ends of the multiple connecting pieces 174. Gaps are provided between adjacent connecting pieces 174, forming a channel for the dust-laden airflow to pass through. The retaining ring 173 and the baffle 175 are coaxial. The diameter of the lower end of the baffle 175 is smaller than the diameter of the lower end of the retaining ring 173, and the diameter of the lower end of the baffle 175 is larger than the diameter of the upper end of the retaining ring 173.

[0043] Reference Figures 3-4 Under the suction of the exhaust fan 18, the dust-laden airflow enters the second support tower 15 and impacts the upward-facing baffle 175 at the top of the cone. Large dust particles are intercepted and slide down along the baffle 175. The lower end of the baffle ring 173 forms a seal against the inner wall of the second support tower 15, and the upper end of the baffle ring 173 is connected to the support cylinder 172. The diameter of the lower end of the baffle 175 is between the upper and lower ends of the baffle ring 173, forcing the airflow into the annular space between the baffle 175 and the inner inclined surface of the baffle ring 173. In this space, the airflow mainly flows upward, but is guided outward by the outward-sloping surface of the baffle ring 173. Finer dust particles slide down after colliding with the inclined surface due to inertia. The intercepted dust falls into the second connecting hopper 19 below and flows back to the water tank 5 through the extension pipe 191. The purified air rises through the gap between the connecting pieces 174 and is drawn out by the exhaust fan 18.

[0044] Reference Figure 1 and Figure 5The connecting pipe 13 is located between the first support tower 11 and the second support tower 15. One end of the connecting pipe 13 is fixedly connected to the upper end of the first support tower 11, and the support box 14 is fixedly connected to the side wall of the second support tower 15 near the lower end. The other end of the connecting pipe 13 is fixedly connected to the support box 14. Both ends of the connecting pipe 13 are connected to the first support tower 11 and the support box 14 respectively, and the support box 14 is connected to the second support tower 15. A guide plate 141 is fixedly connected to the side wall of the support box 14 away from the first support tower 11. An acute angle is provided between the guide plate 141 and the side wall of the support box 14. A guide groove 1411 is provided on the guide plate 141, which communicates with the support box 14. A speed reduction plate 142 is installed on the support box 14. Specifically, the end of the speed reduction plate 142 extends into the support box 14 through the guide groove 1411. A fixing screw 143 is threadedly connected to the guide plate 141. The fixing screw 143 is used to position the speed reduction plate 142 on the guide plate 141. The speed reduction plate 142 is used to adjust the air intake from the support box 14 to the second support tower. Specifically, by extending or withdrawing the speed reduction plate 142 into or out of the support box 14, the effective flow area of ​​the airflow between the support box 14 and the second support tower 15 is changed, thereby controlling the airflow speed entering the second support tower 15.

[0045] Reference Figures 3-5 The inclined deceleration plate 142 forces the airflow entering the support box 14 to change direction, inducing a strong rotating airflow. The centrifugal force generated by the rotating airflow throws dust particles toward the inner wall of the second support tower 15, causing the dust particles to collide and settle. The deceleration plate 142 obstructs the dust-laden airflow, thereby increasing the residence time of the dust-laden airflow and promoting particle settling. Some medium and coarse dust particles are pre-separated, thereby reducing the burden on the subsequent filter assembly 17 to separate dust particles from the dust-laden airflow.

[0046] Reference Figures 5-7A first observation window 144 is installed on the side wall of the support box 14 away from the second support tower 15. A second observation window 146 is installed on the side wall of the support box 14 close to the first support tower 11. A third observation window 148 is installed on the side wall of the second support tower 15 away from the first support tower 11, and the third observation window 148 is installed near the filter assembly 17.

A third clamping member 149 is installed on the side wall of the second support tower 15. The third clamping member 149 is used to clamp the third observation window 148 onto the outer side wall of the second support tower 15. The first observation window 144, the second observation window 146, and the third observation window 148 are all made of transparent material. The first observation window 144 is mainly used to observe the internal condition of the support box 14, the second observation window 146 is mainly used to clean the dust adsorbed on the speed reduction plate 142, and the third observation window 148 is mainly used to observe and clean the filter assembly 17.

One side of the first observation window 144 is rotatably connected to the side wall of the support box 14. The first clamping member 145 includes a clamping wrench 1451, a mounting base 1452, a connecting pin 1453, a connecting latch 1454, and a connecting seat 1455.

The other end of the connecting latch 1454 is sleeved on the connecting seat 1455. When it is necessary to open the first observation window 144, turn the clamping wrench 1451 away from the support box 14, then disengage the connecting latch 1454 from the connecting seat 1455, and then open the first observation window 144. When it is necessary to lock the first observation window 144, first hang the latch on the connecting seat 1455, then turn the clamping wrench 1451 towards the support box 14 until the connecting latch 1454 is tightened between the clamping wrench 1451 and the connecting seat 1455, thereby pressing the first observation window 144 against the side wall of the support box 14.

[0048] Reference Figure 9A water inlet pipe 51 is fixedly connected to one side wall of the water tank 5, and a water inlet valve 511 is fixedly connected to the water inlet pipe 51. The spraying mechanism 2 includes a water pump 21, a water pumping pipe 22, a water delivery pipe 23, a spraying support pipe 24, a main spraying assembly 25, and a secondary spraying assembly 26.

One end of the water delivery pipe 23 is fixedly connected to the water pump 21. The spraying support pipe 24 is vertically arranged and fixedly connected to the water tank 5. The other end of the water delivery pipe 23 is fixedly connected to the spraying support pipe 24. When the water inlet valve 511 is opened, appropriate water is injected into the water tank 5 through the water inlet pipe 51. Then, the water pump 21 transfers the water in the water tank 5 to the spraying support pipe 24 through the water pumping pipe 22.

[0049] Reference Figure 2 , Figure 9 and Figure 10 In this embodiment, the main spray assembly 25 is partially installed on the spray support pipe 24 and partially installed inside the first support tower 11. In this embodiment, the main spray assembly 25 is provided in two sets, and the main spray assembly 25 includes a first water valve 251, a first spray pipe 252, a second spray pipe 253 and a turbine fan 256. One end of the first spray pipe 252 is fixedly connected to the spray support pipe 24, and the first water valve 251 is fixedly connected to the first spray pipe 252. The axis of the first spray pipe 252 is perpendicular to the axis of the spray support pipe 24. The other end of the first spray pipe 252 extends into the first support tower 11. A second spray pipe 253 is fixedly connected to the first spray pipe 252. The second spray pipe 253 is located inside the first support tower 11. The axis of the second spray pipe 253 is perpendicular to the axis of the spray support pipe 24. The first spray pipe 252 and the second spray pipe 253 are connected. The upper and lower side walls of the first spray pipe 252 are each provided with 4 spray heads 254, and the upper and lower side walls of the second spray pipe 253 are each provided with 4 spray heads 254. A dispersion block 255 is fixedly connected to the nozzle of the spray head 254. The geometry of the dispersion block 255 is a tapered conical spiral block. The diameter of the dispersion block 255 near the nozzle of the spray head 254 is larger than the diameter away from the nozzle of the spray head 254. The purpose of this design is to guide the water flow to accelerate diffusion through the tapered conical structure of the dispersion block 255, and to use the spiral pattern on its surface to force the water flow to rotate, divide, and violently shear, ultimately breaking and dispersing the concentrated water flow sprayed from the spray head 254 into fine droplets or highly turbulent water flow.

[0050] Reference Figures 1-3A turbine fan 256 is fixedly connected inside the first support tower 11. The turbine fan 256 is positioned above the first spray pipe 252 and the second spray pipe 253, and is coaxial with the first support tower 11. When the exhaust fan 18 is started, a strong negative pressure is generated at the exhaust port of the exhaust fan 18. This negative pressure is transmitted through the second support tower 15, support box 14, connecting pipe 13, and first support tower 11 to the inlet of the suction pipe 111. The negative pressure generated by the exhaust fan 18 drives the dust-laden airflow to flow at high speed through the blades of the turbine fan 256. The aerodynamic torque generated by the airflow acting on the blades drives the fan to rotate. The turbine fan 256 is used to mix the water sprayed into the first support tower 11 with the dust, so that the subsequent filter assembly 17 can filter the dust.

[0051] Reference Figures 11-12 In this embodiment, two sets of secondary spraying components 26 are provided, both sets of which are installed on the connecting pipe 13. Taking one set of secondary spraying components 26 as an example, the secondary spraying component 26 includes a second water valve 261, a third spray pipe 262, and a dispersion plate 263. One end of the third spray pipe 262 is fixedly connected to the spray support pipe 24, and the other end of the third spray pipe 262 extends into the connecting pipe 13. The axis of the third spray pipe 262 is perpendicular to the axis of the spray support pipe 24. The second water valve 261 is fixedly connected to the third spray pipe 262 and is located outside the connecting pipe 13. The dispersion plate 263 is horizontally fixedly connected inside the connecting pipe 13 and is located above the third spray pipe 262. The third spray pipe 262 extending into the connecting pipe 13 is provided with a water nozzle 2621, which faces the dispersion plate 263. The water jet from nozzle 2621 hits the spray plate, thus breaking up the water jet so that the water can mix with the dust-laden airflow again.

[0052] Reference Figure 1 , Figure 3 and Figure 4 The dust-laden airflow, after being mixed with water twice, enters the second support tower 15 from the support box 14. After passing through the filter assembly 17, the dust and water in the airflow are filtered out, and the purified air is drawn away by the exhaust fan 18. Specifically, the dust-laden, humid airflow entering the second support tower 15 impacts the conical baffle 175, while large dust particles and water droplets are intercepted and slide off. Because the lower end of the baffle ring 173 is sealed against the tower wall, the airflow is forced to turn towards the annular space between the baffle 175 and the inclined surface of the baffle ring 173. The airflow flows along the inclined inner wall of the baffle ring 173, and finer dust particles and water droplets collide with the inclined surface, are captured, and slide off. The mixture of dust and water droplets that slide off falls into the second connecting hopper 19 and flows back to the water tank 5, while the purified air is drawn upward by the exhaust fan 18.

[0053] Reference Figure 1 , Figure 3 and Figure 13The dust scraping mechanism 3 includes a transmission assembly 31 and a support assembly 32. The transmission assembly 31 is partially installed on the water tank 5 and partially installed on the support assembly 32. The transmission assembly 31 includes a first support shaft 311, a second support shaft 312, a third support shaft 313, a dust scraper 318, a chain, and a dust scraper motor 319. The first support shaft 311 and the second support shaft 312 are arranged along the length direction of the water tank 5, and the axes of the first support shaft 311 and the second support shaft 312 are perpendicular to the length direction of the water tank 5, respectively. The first support shaft 311 and the second support shaft 312 are rotatably connected to the water tank 5. The first support shaft 311 is located below the first support tower 11, and the second support shaft 312 is located below the second support tower 15. A sprocket 314 is fixedly connected to each end of the first support shaft 311 and the second support shaft 312. The support assembly 32 includes a support frame 321, a connecting box 322, and a dust discharge box 323. The connecting box 322 is inclined, with its upper end tilted away from the second support tower 15. The lower end of the connecting box 322 is fixedly connected to the end of the water tank 5 near the second support tower 15. An observation port 3221 is provided on the upper top wall of the connecting box 322, and an observation cover plate 3222 is rotatably connected to the upper top wall of the connecting box 322. The support frame 321 is installed below the connecting box 322, with its upper end fixedly connected to the lower bottom wall of the connecting box 322. The dust discharge box 323 is located below the connecting box 322, vertically connected to the upper end of the connecting box 322, and has a dust discharge port at its lower end.

[0054] Reference Figure 3 , Figure 13 and Figure 14 The third support shaft 313 is rotatably connected inside the connecting box 322. The third support shaft 313 is also located at the upper end of the dust outlet box 323. The axis of the third support shaft 313 is parallel to the axis of the second support shaft 312. A sprocket 314 is fixedly connected to each end of the third support shaft 313. In this embodiment, two chains are provided, namely the first chain 315 and the second chain 316. The first chain 315 is hooked onto the sprocket 314 on the same side of the first support shaft 311, the second support shaft 312, and the third support shaft 313. Similarly, the second chain 316 is hooked onto the sprocket 314 on the other side of the first support shaft 311, the second support shaft 312, and the third support shaft 313. On the first chain 315 and the second chain 316, a plurality of mounting plates 317 are fixedly arranged at intervals along their length. The dust scraper 318 is L-shaped and includes a horizontal section and a vertical section. The two ends of the horizontal section of the dust scraper 318 are fixedly connected between two mounting plates 317 at corresponding positions on the two side chains 315. The lower end of the vertical section abuts against the inner bottom wall of the water tank 5 and the lower end of the vertical section abuts against the inner bottom wall of the connecting box 322.

[0055] Reference Figure 1 , Figure 3 and Figure 14 A reducer 3110 is fixedly connected to the side wall of the connecting box 322. The output end of the reducer 3110 is fixedly connected to the third support shaft 313. The dust scraper motor 319 is fixedly connected to the reducer 3110. The dust scraper motor 319 transmits power to the third support shaft 313 through the reducer 3110. When the dust scraper motor 319 is working, it drives the third support shaft 313 to rotate through the reducer 3110. The third support shaft 313 then engages with the chain drive through the sprocket 314. The chain then drives the dust scraper plate 318 to move through the mounting plate 317. The dust scraper plate 318 scrapes the dust that has settled on the bottom wall of the water tank 5 along the bottom wall of the water tank 5 to the bottom wall of the connecting box 322, and continues to scrape it to the connection port 324 between the dust outlet box 323 and the connecting box 322. Then the dust falls down from the top of the dust outlet box 323 and is finally discharged from the dust outlet. Since the connecting box 322 is set at an angle, the water that is scraped from the water tank 5 onto the connecting box 322 by the dust scraper 318 will flow back into the water tank 5 along the inner bottom wall of the connecting box 322.

[0056] The implementation principle of a dual-tower water dust collector according to an embodiment of this application is as follows: The exhaust fan 18 generates negative pressure, and dust-laden exhaust gas enters the first support tower 11 through the suction pipe 111. Coarse dust particles settle directly into the water tank 5 due to gravity via the first connecting hopper 12. The spraying mechanism 2 draws water from the water tank 5 into the first support tower 11 and sprays it through the spray head 254. The turbine fan 256 rotates under the influence of the airflow, enhancing the mixing of water and dust. The mixed airflow enters the connecting pipe 13, where the secondary spraying assembly 26 sprays water for secondary mixing. The airflow forms a vortex through the adjustable deceleration plate 142 inside the support box 14, and centrifugal force causes medium and coarse particles to impact and settle against the box wall. After entering the second support tower 15, the airflow impacts the baffle 175, slowing it down and intercepting large particles. The airflow is forced to enter the inclined channel between the baffle 175 and the baffle ring 173, where fine particles are captured by collision and centrifugal force and slide down the inclined surface to the water tank 5. The purified gas is discharged by the exhaust fan 18. Dust settling at the bottom of water tank 5 is scraped along the chain by dust scraper 318 to dust collection box 323, and automatically discharged from the dust outlet. Control box 4 centrally regulates the operation of dust collection mechanism 1, spraying mechanism 2 and dust scraping mechanism 3.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
