Description
Technical Field
[0001] This utility model relates to the technical field of wet cyclone dust collectors, specifically to a wet cyclone dust collector. Background Technology
[0002] Most existing wet cyclone dust collectors draw in dust-laden air through a dust hood and suction duct. Inside the collection box, water mist thoroughly wets the fine dust particles, causing them to collide and agglomerate, forming a dust-water mixture. This mixture is then intercepted by the cyclone dust collector and dehydration device, forming sludge. Driven by the airflow, this sludge is collected in the diffusion and water collection section and discharged through a drain pipe. The purified air is then released into the roadway, achieving dust removal and purification of the dust-laden airflow. However, most existing dust collectors have a single cyclone dust collection structure inside the collection box, resulting in a relatively large size and high pressure loss. Utility Model Content

Each through hole is used to allow dust particles to enter the air duct.
[0010] Based on the above technical solution, the present invention can be further improved as follows:
[0011] Furthermore, the swirl structure includes multiple swirl tubes, each of which includes a tube body and a helical blade. The axial direction of the tube body is the same as the extension direction of the air duct, and the helical blade is connected to the inner wall surface of the tube body.
[0012] Multiple through holes are provided in the tube body;
[0013] Each of the swirling cavities is defined between each of the tube bodies and the corresponding helical blades.
[0014] Furthermore, for each of the tubes, the total area of the plurality of through holes accounts for 9% to 12% of the area of the inner wall surface of the corresponding tube.
[0015] Furthermore, each of the cyclone tubes also includes a connecting shaft, the axial direction of which is the same as the axial direction of the tube body;
[0016] The spiral blades are spirally connected to the periphery of the connecting shaft.
[0017] Furthermore, the swirl structure also includes at least two mounting plates, which are disposed opposite to each other in the air duct along the extension direction of the air duct and are adapted to the cross-section of the air duct. Both mounting plates are provided with a plurality of mounting through holes distributed in an array, and the plurality of mounting through holes of one mounting plate are arranged in a one-to-one correspondence with the plurality of mounting through holes of the other mounting plate.
[0018] Each of the tubes is inserted into two opposite mounting through holes along the extension direction of the air duct, and each of the tubes is adapted to the corresponding two mounting through holes.
[0019] Furthermore, the spraying device includes:
[0020] A spray pipe is installed inside the air duct, and the spray pipe is close to the air inlet;
[0021] A water inlet pipe, connected to the outside of the housing, is connected to the spray pipe; and...
[0022] Multiple spray heads are installed in the spray pipe and are distributed at intervals along the extension direction of the spray pipe.
[0023] Furthermore, the spray pipe is arranged in a ring shape, surrounding the inner perimeter of the air duct, and the outer peripheral wall of the spray pipe forms part of the peripheral side of the outer shell, and the outer peripheral wall of the spray pipe is provided with a water inlet.
[0024] The water inlet pipe is located on the outer casing, and the water inlet pipe has an outlet that communicates with the water inlet.
[0025] Furthermore, the lower side of the outer shell is provided with a connecting through hole, which corresponds to the vortex structure;

[0031] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0032] The negative pressure exhaust port draws in the flue gas, which enters the duct through the inlet and is initially cleaned by the high-density water mist sprayed by the spray structure. Before reaching the swirl structure, the gas undergoes regular mixing before entering the multiple swirl chambers, where it spirals. During gas-liquid mixing and entry into the swirl chambers, dust particles in the gas collide violently with water mist particles, becoming wetted and captured, increasing in mass and volume as well as inertia to form large dust particles. A water film forms on the walls of each swirl chamber, capturing the large dust particles. Due to the multiple through-holes, the pressure between the multiple swirl chambers is greater than the pressure within each individual swirl chamber; under inertia, the large dust particles in the water film are thrown into the duct, collect at the drainage structure, and discharged outside the duct. The clean gas formed after treatment is extracted by the exhaust port. In this way, the flue gas is sequentially dusted through the spray structure and the multiple swirl structures in the pre- and mid-stages, resulting in high dust removal efficiency, good effect, and small volume and pressure loss.

[0047] Please refer to Figure 1 , Figure 3 and Figure 7 This utility model provides a wet cyclone dust collector, including a shell 1, a spray structure 2, a drainage structure 3, and a cyclone structure 4; the shell 1 forms a through air duct 11, and the two ends of the air duct 11 respectively form an air inlet 111 and an air outlet 112; the spray structure 2 is used to spray water toward the air inlet 111; the drainage structure 3 is connected to the lower side of the shell 1 and is used to discharge the water in the air duct 11; the cyclone structure 4 is disposed in the air duct 11, and the cyclone structure 4 includes a plurality of cyclone chambers 411, each of the cyclone chambers 411 is arranged in a spiral shape, and the cavity wall of each cyclone chamber 411 is provided with a plurality of through holes 4121, each of the through holes 4121 is used to allow dust particles to enter the air duct 11.
[0048] The negative pressure exhaust port 112 draws in smoke and dust, which enters the air duct 11 through the air inlet 111. The high-density water mist sprayed by the spray structure 2 provides initial dust removal. Before reaching the swirl structure 4, the gas undergoes regular mixing before entering the multiple swirl chambers 411, where it spirals. During gas-liquid mixing and entry into the swirl chambers 411, dust particles in the gas collide violently with water mist particles, becoming wetted and captured, increasing in mass and volume, and inertial force to form larger dust particles. Furthermore, a water film forms on the walls of each swirl chamber 411, which captures the larger dust particles. Because of the multiple through holes 4121, the pressure between the multiple swirling chambers 411 is greater than the pressure within each individual swirling chamber 411. Under the action of inertia, large dust particles in the water film are thrown into the air duct 11, collect at the drainage structure 3, and are discharged outside the air duct 11. The clean gas formed after treatment is extracted by the air outlet 112. In this way, the flue gas is sequentially dusted after passing through the spray structure 2 and the multiple swirling structures 4 in the pre- and mid-stages, resulting in high dust removal efficiency, good effect, and small volume and pressure loss.
[0049] It should be noted that, in this embodiment, the width and height of the outer casing 1 are only 1.4 to 1.6 times the diameter of the outlet and inlet ducts. The length of the outer casing 1 is 1.9 to 2.1 times the diameter of the outlet and inlet ducts. Furthermore, the pressure drop of the wet cyclone dust collector is only 700 Pa to 900 Pa.
[0050] Specifically, refer to Figure 1 and Figure 7 In this embodiment, each of the swirling structures 4 includes multiple swirling tubes 41, each swirling tube 41 including a tube body 412 and a helical blade 413. The axial direction of the tube body 412 is the same as the extending direction of the air duct 11, and the helical blade 413 is helically connected to the inner wall surface of the tube body 412. Multiple through holes 4121 are provided in the tube body 412. Each swirling cavity 411 is defined between each tube body 412 and the corresponding helical blade 413, thereby making the swirling cavity 411 helically arranged. The structure is simple and easy to manufacture.
[0051] In another embodiment, each of the swirling structures includes a plurality of helical tubes, each of the helical tubes being helically bent.
[0052] More specifically, in this embodiment, reference continues to be made to... Figure 1 and Figure 7Each of the cyclone tubes 41 further includes a connecting shaft 414, the axial direction of which is the same as the axial direction of the tube body 412. The helical blade 413 is helically connected to the periphery of the connecting shaft 414, and the side of the helical blade 413 facing away from the connecting shaft 414 is connected to the inner wall surface of the tube body 412. This facilitates the installation of the helical blade 413 and the tube body 412.
[0053] In this invention, to ensure that the pressure in the space between the multiple tubes 412 is greater than the pressure within each of the swirling cavities 411, thus facilitating the ejection of large dust particles from the water film into the space between the multiple tubes 412, in this embodiment, the total area of the multiple through holes 4121 accounts for 9% to 12% of the area of the inner wall surface of the corresponding tube 412. This makes the space between the multiple tubes 412 almost a dead space, meaning that the gas flow within it is minimal, almost nonexistent. Therefore, the pressure in the space between the multiple tubes 412 is relatively high, while the pressure within each of the swirling cavities 411 is relatively low. Within each of the swirling cavities 411, large dust particles are ejected to the water film due to inertia, where they are captured by the water film or directly ejected through it. At this time, dust particles in the airflow can also be wetted and captured by the water film to form large dust particles. Large dust particles have a greater inertial force, and the pressure outside each of the swirling chambers 411 is less than the pressure inside each of the swirling chambers 411, so that large dust particles are thrown out from the water film or through the water film via the through hole 4121.
[0054] In this embodiment, the effect is best when the total area of the plurality of through holes 4121 accounts for 10% of the area of the inner wall surface of the corresponding tube body 412. This allows a water film to be continuously formed on the inner wall surface of each tube body 412, while facilitating the ejection of large dust particles from or through the water film.
[0055] In this invention, the shape of the air duct 11 is not limited, as long as the air outlet 112 and the air inlet 111 can be connected to the air inlet pipe and the air outlet pipe. In this embodiment, refer to... Figure 1 and Figure 3 The cross-section of the middle part of the air duct 11 is rectangular, the two ends of the outer shell 1 are tapered in opposite directions, and the air inlet 111 and the air outlet 112 are circular to match the air inlet pipe and the air outlet pipe.
[0056] Specifically, in order to install multiple tubes 412, in this embodiment, referring to Figure 1 , Figure 3 and Figure 7The vortex structure 4 further includes at least two mounting plates 42. The two mounting plates 42 are disposed opposite each other in the middle of the air duct 11 along the extension direction of the air duct 11, and are both rectangular in shape to match the cross-section of the middle of the air duct 11, thereby forming a closed space between the two mounting plates 42. Each of the two mounting plates 42 is provided with a plurality of mounting through holes distributed along the array, and the plurality of mounting through holes of one mounting plate 42 are respectively corresponding to the plurality of mounting through holes of the other mounting plate 42. Each tube body 412 passes through the two opposite mounting through holes along the extension direction of the air duct 11, and each tube body 412 is adapted to the two corresponding mounting through holes, so that each tube body 412 is located in the closed space. Each vortex cavity 411 is connected to the closed space through the corresponding plurality of through holes 4121, so that when the air outlet 112 is drawn, the space gap between the plurality of tube bodies 412 is almost a dead space.
[0057] More specifically, in this embodiment, the distance between the two mounting plates 42 is adapted to the length of each of the tubes 412, and the two ends of each tube 412 are respectively installed in two mounting through holes that are distributed opposite to each other along the extension direction of the air duct 11; large dust particles are thrown out from each of the through holes 4121 into the space between the multiple tubes 412. The large dust particles have a large mass, volume and inertial force, so the large dust particles fall from top to bottom and are collected and discharged by the drainage structure 3.
[0058] In this embodiment, refer to Figure 1 , Figure 4 and Figure 6 The spraying device includes a spray pipe 21, a water inlet pipe 22, and multiple spray heads 23. The spray pipe 21 is located inside the air duct 11 and is close to the air inlet 111. The water inlet pipe 22 is connected to the outside of the outer casing 1 and communicates with the spray pipe 21. The multiple spray heads 23 are all located on the spray pipe 21 and are spaced apart along the extension direction of the spray pipe 21. The water inlet pipe 22 fills the spray pipe 21 with water, and then the multiple spray heads 23 spray out high-density water mist.
[0059] Furthermore, the spray pipe 21 is disposed within the air duct 11 and is located near the air inlet 111, with a certain distance between the spray pipe 21 and the vortex. The spray pipe 21 is arranged in a ring, surrounding the inner perimeter of the air duct 11. The outer peripheral wall of the spray pipe 21 forms part of the peripheral side surface of the outer shell 1, and the outer peripheral wall of the spray pipe 21 is provided with a water inlet 211; the water inlet pipe 22 is disposed within the outer shell 1, and the water inlet pipe 22 is provided with a water outlet 221 communicating with the water inlet 211.
[0060] In this embodiment, refer to Figure 1 , Figures 4 to 6 The spray pipe 21 is integrally formed with the outer casing 1, and the spray pipe 21 is rectangular. The water inlet pipe 22 is located on the upper side of the spray pipe 21, and the size of the water inlet 211 is adapted to the upper part of the outer peripheral wall of the spray pipe 21. The water outlet 221 surrounds the periphery of the water inlet 211, allowing water in the water inlet pipe 22 to quickly enter the entire spray pipe 21. The design is aesthetically pleasing and efficient. The spray pipe 21 is located between the air inlet 111 and the vortex structure 4, and is spaced apart from the vortex structure 4. Multiple spray heads 23 are distributed circumferentially along the spray pipe 21. Thus, after the flue gas enters the air inlet 111, the multiple spray heads 23 spray high-density water mist to surround the flue gas, achieving efficient preliminary dust removal. A regular mixed flow is formed in the space between the spray pipe 21 and the vortex structure 4, facilitating gas-liquid mixing.
[0061] In this embodiment, refer to Figure 1 and Figure 3 The lower side of the outer casing 1 is provided with a connecting through hole, which corresponds to the vortex structure 4. The drainage structure 3 includes a drainage hopper 31 and a drainage pipe 32. The drainage hopper 31 is connected to the lower side of the air duct 11 and surrounds the connecting through hole, with the tip of the drainage hopper 31 pointing downwards. The drainage pipe 32 is connected to the lower end of the drainage hopper 31. Large dust particles thrown out fall into the drainage hopper 31, are collected in the drainage hopper 31, and are then discharged through the drainage pipe 32.
[0062] Furthermore, in this embodiment, reference continues to be made to... Figure 1 and Figure 3 The drainage hopper 31 has an opening on one side; the wet cyclone dust collector also includes a cover plate 5, which is bolted to the opening. During normal operation of the wet cyclone separator, the cover plate 5 is installed in the opening. When maintenance or cleaning of the drainage hopper 31 is required, the bolts are removed to take off the cover plate 5 to open the opening. The opening is circular, and the cover plate 5 is also circular. The drainage hopper 31 has multiple threaded holes corresponding to the opening, and the cover plate 5 has multiple mounting holes that correspond one-to-one with and are connected to the multiple threaded holes. Multiple bolts are threaded into the multiple threaded holes, one-to-one passing through the multiple mounting holes, to install the cover plate 5 in the opening.
[0063] To observe the air duct 11, in this embodiment, refer to... Figure 1 and Figure 4The outer casing 1 has at least two observation ports 12 on one side, each corresponding to a position between the cyclone structure 4 and the air inlet 111. The wet cyclone dust collector also includes at least two door panels 6, each door panel 6 having one side rotatably connected to a corresponding observation port 12, allowing the other side of each door panel 6 to be flipped to move closer to or away from the observation port 12. This allows the corresponding door panel 6 to be opened to observe the operation within the air duct 11, or to facilitate maintenance.
[0064] Specifically, in this embodiment, one side of each door panel 6 is hinged to the outer casing 1, such that the other side of the door panel 6 is close to or far from the observation port 12. In another embodiment, one side of each door panel 6 can also be rotatably connected to the outer casing 1 via a pivot or a hinge.
[0065] In this embodiment, refer to Figure 1 and Figure 2 Each door panel 6 is provided with a plurality of locking components 7 on its periphery. The plurality of locking components 7 are distributed at intervals along the periphery of the observation port 12. Each locking component 7 includes a hinge seat 71, a screw 72, a stop block 73, a nut 74 and a handle 75. Each hinge seat 71 is provided on the periphery of the corresponding observation port 12. One end of the screw 72 is hinged to the hinge seat 71 with a certain interference so that the other end of the screw 72 can rotate closer to or further away from the door panel 6. The stop block 73 is provided with a notch 731, and the other end of the screw 72 passes through the notch 731. The nut 74 is screwed to the other end of the screw 72 and presses against the side of the stop block 73 away from the hinge seat 71 so that the stop block 73 abuts against the door panel 6. The handle 75 is connected to one end of the screw 72 and extends radially along the screw 72 so as to facilitate manual gripping and rotation of the screw 72. Furthermore, there is no limitation on the amount of interference between one end of the screw 72 and the hinge seat 71, as long as the screw 72 does not rotate away from the door panel 6 when the stop block 73 abuts against the door panel 6.
[0066] In this embodiment, three observation ports 12 are provided, corresponding to three door panels 6. Of the three observation ports 12, one observation port 12 corresponds to the position between the vortex structure 4 and the air inlet 111, and the other two observation ports 12 correspond to the vortex structure 4. The other two observation ports 12 are distributed at intervals along the length direction of the plate on which the outer shell 1 is located, so as to be able to view more of the vortex cavities 411.
