Summary of the Utility Model

[0004] The technical problem to be solved by this application is to provide a horizontally arranged wet high-efficiency dust collector, which can further process the soot that has not been removed after secondary dust removal, thereby improving the dust removal effect of the wet high-efficiency dust collector.

[0005] To solve the above technical problem, this application adopts the following technical solutions:

[0006] This application provides a horizontally arranged wet high-efficiency dust collector, including a first barrel, with an air inlet on one side of the first barrel, and a fan is also provided inside the first barrel; a second barrel, connected to the first barrel, with an inclined wind baffle provided inside the second barrel, and both horizontal sides of the wind baffle are in contact with the barrel wall of the second barrel; a water spraying device, including a first spraying assembly and a second spraying assembly, the first spraying assembly is located at the position of the air inlet, and the second spraying assembly is located between the first barrel and the wind baffle.

Detailed implementation manners

[0023] The following will describe the technical solutions in some embodiments of the present application in combination with the drawings in some embodiments of the present application.

[0024] It should be noted that: Similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] Such as Figure 1 And 2As shown in the figure, an embodiment of the present application provides a horizontal wet high-efficiency dust collector, which includes a first barrel 1 and a second barrel 2 connected to each other. Among them, one side of the first barrel 1 is an air inlet, and the soot can enter from the air inlet. A fan 3 is also provided in the first barrel 1. After the fan 3 is started, it can generate negative pressure to suck the soot into the first barrel 1. The second barrel 2 is connected to the first barrel 1, and an inclined windshield 4 is provided in the second barrel 2. The windshield 4 is used to block the airflow. The first spray assembly 12 located at the air inlet position first sprays water on the soot in the first barrel 1 to achieve primary dust removal. The soot after primary dust removal enters the second barrel 2. After being sprayed with water by the second spray assembly 13 located between the first barrel 1 and the windshield 4, secondary dust removal is performed on the soot. At this time, most of the soot will flow into the first drainage groove 11 and the second drainage groove 21 respectively, while a small part of the soot still has not been mixed with the water mist and continues to flow with the airflow and is blocked by the windshield 4. Using the principle of inertial dust removal, that is, using the difference in inertial forces between the soot and the gas during movement to separate the dust-containing liquid droplets from the gas. By setting the windshield 4, when the soot and the airflow encounter the windshield 4, the dust-containing liquid droplets are separated from the gas, and the soot is separated from the airflow by using the difference in inertial forces between the soot and the gas, so as to achieve the purpose of dust removal, so that after the wet high-efficiency dust collector has undergone two dust removals, it can still perform dust removal one more time to improve the dust removal effect.

[0026] Optionally, both sides of the windshield 4 in the horizontal direction are in contact with the barrel wall of the second barrel 2, so as to improve the shielding area of the windshield 4 and prevent the airflow from flowing out from both sides of the windshield 4 in the horizontal direction.

[0027] Optionally, the windshield 4 can be a steel plate, which has a low cost and is simple to manufacture.

[0028] Optionally, the first barrel 1 includes a main body section 14 and a tapered section 15 connected to each other. The size of the tapered section 15 is smaller than that of the main body section 14, so that the soot that has not been mixed with the water mist can gradually converge in the tapered section 15 and is convenient to flow into the connection section 6 centrally. Of course, since the tapered section 15 is a curved surface structure, the tapered section 15 is also convenient to guide the mixture of the soot and the water mist to flow into the first drainage groove 11.

[0029] Optionally, the main body section 14 and the tapered section 15 can be connected by welding. Of course, they can also be connected by bolts.

[0030] Optionally, a first drainage groove 11 is provided at the bottom of the main body section 14. The first drainage groove 11 is communicated with the main body section 14. By setting the first drainage groove 11, the mixture of the soot and the water mist in the first barrel 1 can be collected and discharged.

[0031] Such as Figure 2As shown, as an implementation manner, the wind deflector 4 includes a horizontal portion 41 and an inclined portion 42. The horizontal portion 41 is connected to the second barrel 2, and the inclined portion 42 extends obliquely away from the fan 3, enabling the air flow to enter the second barrel 2. Moreover, the projected area of the inclined portion 42 in the direction of the air inlet of the second barrel 2 exceeds half of the area of the air inlet of the second barrel 2, making the area of the inclined portion 42 large enough to block more air flow and improve the dust removal effect.

[0032] Optionally, the air inlet of the second barrel 2 is the opening connected to the first barrel 1.

[0033] Optionally, the horizontal portion 41 can be connected to the second barrel 2 by bolts or welding.

[0034] Optionally, the second barrel 2 can be of a cuboid structure, enabling the vertical sides on both sides of the inclined portion 42 to abut against the second barrel 2.

[0035] Optionally, the area of the horizontal cross-section of the second barrel 2 is larger than the volume of the air inlet of the second barrel 2, which plays a role in expanding the air flow entering the second barrel 2. The air flow entering the second barrel 2 will have a reduced flow rate due to the increased volume of the second barrel 2. After the flow rate is reduced, it cannot drive the mixture of dust and water mist, so that the mixture of dust and water mist can flow into the second drainage trough 21, which also achieves the effect of dust removal.

[0036] As Figure 2 As shown, as an implementation manner, the exhaust port direction of the second barrel 2 is set upward, and the direction of the exhaust port forms an angle with the flow direction of the air flow blocked by the wind deflector 4, thereby being able to play a role in reducing the flow rate. On the one hand, it enables the mixture of dust and water mist to fall into the second drainage trough 21 by its own gravity; at the same time, it also enables the dust in the air flow not to drive the dust, causing the dust to also fall into the second water collecting trough. A wind distribution plate 5 for reducing the wind speed is also provided in the second barrel 2.

[0037] Optionally, a number of wind distribution holes are evenly distributed on the wind distribution plate 5, and the opening ratio of the wind distribution plate 5 is 0.32 - 0.4. After the air flow containing dust passes through the wind distribution plate 5, through the impact with the wind distribution plate 5, the flow rate of the air flow containing dust is reduced, so that the air flow cannot drive the dust, and the dust falls into the second drainage trough 21 by its own gravity, thereby improving the dust removal effect of the wet high-efficiency dust collector.

[0038] As an implementation manner, one end of the wind distribution plate 5 is connected to the barrel wall of the second barrel 2, and the other end is connected to the inclined portion 42, thereby being able to meet the stability of the wind distribution plate 5.

[0039] Optionally, the end of the wind distribution plate 5 connected to the second barrel 2 can be connected by bolts or welding, and the position connected to the inclined portion 42 can also be connected by bolts or welding.

[0040] As Figure 1 and 2 shown, as an implementation manner, the first barrel 1 is connected to the second barrel 2 through a connecting section 6. At least one vibrating wire filter plate 7 is installed on the connecting section 6. By setting the connecting section 6, an installation space is provided for the vibrating wire filter plate 7, and the vibrating wire filter plate 7 is located between the second spray assembly 13 and the wind shield 4. The vibrating wire filter plate 7 can play the role of dust collection and filtration. After the fan 3 is started, a swirling air flow is formed. The first spray assembly 12 sprays water for atomization at the position of the air inlet of the first barrel 1, and there is a large amount of water mist, so that the soot and the water mist are mixed, playing the role of primary dust removal; and the soot that is not mixed with the water mist continues to flow. Since the vibrating wire filter plate 7 is located between the wind shield 4 and the second spray assembly 13, therefore, before the soot enters the second barrel 2, it will also be mixed with the water mist of the second spray assembly 13, so that the mixture of the soot and the water mist directly falls on the vibrating wire filter plate 7, and the vibrating wire filter plate 7 further realizes the functions of dust collection and filtration, thereby improving the dust removal effect of the wet high-efficiency dust collector.

[0041] As Figure 3 shown, optionally, the vibrating wire filter plate 7 is usually composed of a bracket, warp stainless steel wires and weft stainless steel wires. The warp stainless steel wires are vertically arranged at intervals on both side surfaces of the bracket, and the weft stainless steel wires are horizontally arranged at intervals in the middle of the bracket. The two warp stainless steel wires and the weft stainless steel wires are separated from each other to form two sets of filter meshes.

[0042] Optionally, the first spray assembly 12 includes a water pipe and a nozzle. Among them, the nozzle is arranged towards the direction of the fan 3, and the water pipe extends to the center position of the air inlet, and sprays water mist around through the nozzle to improve the dust removal effect.

[0043] Optionally, a water pump or the like can be connected to the outside of the water pipe. The first spray assembly 12 has the same structure as the second spray assembly 13.

[0044] Optionally, the connecting section 6 and the first barrel 1 and the second barrel 2 can be respectively connected by bolts.

[0045] Optionally, the connecting section 6 is of a square structure, so as to facilitate connection with the vibrating wire filter plate 7. The connecting section 6 can be provided with two positioning grooves in two opposite directions, such as the upper and lower directions. The vibrating wire filter plate 7 can be inserted into the positioning grooves to play a positioning role.

[0046] As Figure 1 and 2As shown, as an implementation manner, a baffle demister 8 is further installed at the top of the second barrel 2. The baffle demister 8 can play a role in dehydrating, intercepting water mist, so that water flows along the barrel wall of the second barrel 2 into the second drainage tank 21, avoiding a large amount of water mist in the air flow flowing out of the second barrel 2. Of course, after multiple dust removals, a small amount of mixture of soot and water mist falls on the surface of the baffle demister 8, and the baffle demister 8 can also play a role in dust collection.

[0047] Optionally, the baffle demister 8 can be detachably connected to the second barrel 2 by bolts or other clamping forms. On the one hand, the baffle demister 8 can be regularly disassembled and cleaned, and on the other hand, the baffle demister 8 can be regularly replaced.

[0048] Optionally, since the second barrel 2 is of a cuboid structure, it is convenient to connect with the baffle demister 8. Two positioning grooves can be provided in two horizontally opposite directions of the second barrel 2, and the baffle demister 8 can be inserted into the positioning grooves to play a positioning role.

[0049] As Figure 2 shown, as an implementation manner, the fan 3 includes an impeller 32 facing the air inlet and a motor 31 connected to the impeller 32. When the impeller 32 rotates, it can generate a swirling air flow, so that after the soot and water mist are mixed, they move along the outer surface of the waterproof cylinder 9 towards the air guide fan blade 10. The outside of the motor 31 is covered with a waterproof cylinder 9. By setting the waterproof cylinder 9, it can be avoided that water mist enters the fan 3 and causes a short circuit to the motor 31.

[0050] Optionally, the motor 31 can be powered by an external wire.

[0051] Optionally, the waterproof cylinder 9 and the motor 31 can be connected by a flange and bolts.

[0052] As Figure 2 shown, as an implementation manner, an impeller 32 is installed on the output shaft of the motor 31. The impeller 32 includes an impeller rear disc 322 for blocking water. Through the impeller rear disc 322, it can be avoided that water mist and soot enter the motor 31 from the output shaft of the motor 31, thus playing a role in waterproofing and dustproofing.

[0053] Optionally, the impeller rear disc 322 is conical, and the output shaft and the impeller rear disc 322 can be connected by a connecting plate to improve the stability between the impeller rear disc 322 and the output shaft. The impeller 32 further includes blades 321 and a front disc 323. The blades 321 and the front disc 323 are both welded to the impeller rear disc 322. When the output shaft rotates, the impeller 32 is synchronously driven to rotate.

[0054] As an implementation manner, a plurality of supporting members for supporting the waterproof cylinder 9 are further provided on the outer surface of the waterproof cylinder 9, so as to play a role in fixedly supporting the blower 3.

[0055] Optionally, the supporting members are arranged at intervals along the circumferential direction of the waterproof cylinder 9.

[0056] Optionally, the supporting members can be metal members to ensure the structural strength.

[0057] As Figure 2 shown, as an implementation manner, an inclined air guiding fan blade 10 is further provided between the waterproof cylinder 9 and the first barrel 1. The air guiding fan blade 10 is of a bent structure. The inclination and the bent structure of the air guiding fan blade 10 can enable the air flow to form a spiral air flow. Under the action of centrifugal force, the mixture of dust and water mist enters the first drainage groove 11 and flows out of the first barrel 1, achieving the purpose of primary dust removal.

[0058] Optionally, the air guiding fan blade 10 is respectively connected to the waterproof cylinder 9 and the first barrel 1 by welding, so that the air guiding fan blade 10 can also play a supporting role.

[0059] As Figure 2 shown, as an implementation manner, the first barrel 1 includes a first drainage groove 11 at the bottom of the first barrel 1. The first drainage groove 11 is communicated with the chamber inside the first barrel 1. By providing the first drainage groove 11, the mixture of dust and water mist inside the first barrel 1 can be collected and discharged; the second barrel 2 includes a second drainage groove 21 at the bottom of the second barrel 2. The second drainage groove 21 is communicated with the chamber inside the second barrel 2. The mixture of dust and water mist flows into the second drainage groove 21.

[0060] Optionally, the first drainage groove 11 is inclined to facilitate sewage discharge; the second drainage groove 21 is also inclined to facilitate sewage discharge.
