Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a water spray dust removal device. Background Technology

[0002] In existing technologies, dust removal operations typically employ methods such as gravity settling, inertial separation, filtration, wet adsorption, or electrostatic adsorption. These technologies often involve initial filtration of large dust particles from the gas, followed by a second filtration of smaller dust particles using electrostatic or wet adsorption. However, when gas passes through the filter screen, the small pore size causes a decrease in gas velocity. This low-velocity airflow makes it easier for dust to deposit on the filter screen surface, forming a "dust cake" that clogs the pores, reducing the filter's filtration efficiency and overall dust removal effectiveness. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water spray dust removal device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water spray dust removal device, including a dust removal chamber, a dust suction mechanism connected to the side of the dust removal chamber, two filter boxes inside the dust removal chamber, the outer sides of the two filter boxes and the interior of the dust removal chamber being connected by a sealing plate, a spray mechanism above the two filter boxes, two mesh plates inside each of the two filter boxes, multiple stacked PVC multi-faceted hollow spheres between the two mesh plates, and an installation housing installed at the bottom of the two filter boxes, the installation housing communicating with the inner cavity of the filter box, and multiple spirally arranged fan-shaped plates inside the installation housing.

[0005] Preferably, two mounting housings have coaxially arranged mounting rods installed inside them. Multiple fan-shaped plates are spirally installed on the sides of the two mounting rods. The bottom ends of the two mounting rods extend to the bottom of the mounting housings. A square rod is connected between the bottom ends of the two mounting rods. A fixing plate is fitted onto the surface of the square rod. The two ends of the fixing plate are respectively installed on the outside of the two filter boxes. A drive motor is provided above the square rod. A circular plate is installed on the movable end of the drive motor and the top of the square rod. Multiple protrusions arranged at equal angles are installed on the top and bottom of the two circular plates. Adjacent protrusions are staggered in the vertical direction. The fixing plate is elastically connected to one of the circular plates.

[0006] Preferably, a compression spring is fitted onto the surface of the square rod, and the two ends of the compression spring are respectively mounted on the surface of the fixing plate and one of the circular plates.

[0007] Preferably, a connecting rod is connected between the bottom ends of the two mounting rods, and the bottom end of the square rod is mounted on the surface of the connecting rod.

[0008] Preferably, the dust collection mechanism includes a fan, the air inlet of which is connected to an exhaust main pipe, the exhaust main pipe passing through the side of the dust collection chamber and extending to one side of the two filter boxes, the surface of the exhaust main pipe being connected to two exhaust branch pipes, one end of each of the two exhaust branch pipes being installed through the side of the filter box, the bottom end of the dust collection chamber being installed through an air inlet pipe, one end of which is connected to an air duct, and the surface of the air duct is installed through multiple dust collection hoods.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This solution incorporates numerous PVC hollow spheres within the filter box. As airflow rubs against the surface of these spheres, the spheres, being made of plastic, readily generate static electricity, which adsorbs dust particles from the airflow. Furthermore, the larger pore size of the PVC hollow spheres compared to the filter screen allows airflow to pass through these pores, reducing airflow resistance, increasing airflow speed, and ultimately improving dust removal efficiency.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figure 1-5 The water spray dust removal device shown includes a dust collection chamber 23. A dust collection mechanism is connected to the side of the dust collection chamber 23. The dust collection mechanism includes a fan 3 and an air inlet pipe 6. The air inlet of the fan 3 is connected to the main exhaust pipe. The main exhaust pipe passes through the side of the dust collection chamber 23 and extends to one side of two filter boxes 24. Two exhaust branch pipes are connected to the surface of the main exhaust pipe. One end of each of the two exhaust branch pipes passes through and is installed on the side of the filter box 24. The bottom of the dust collection chamber 23 is connected to the air inlet pipe 6. One end of the air inlet pipe 6 is connected to a duct pipe 4. Multiple dust collection hoods 2 are installed through the surface of the duct pipe 4. The dust collection hoods 2 are connected to the duct pipe 4 by flexible hoses. The two ends of the flexible hoses are clamped. Fixed to the dust collection hood 2 and the air duct 4, the control fan 3 is powered on during dust collection. The fan 3 draws out the air from the filter box 24 and the dust collection chamber 23. At this time, the filter box 24 and the dust collection chamber 23 are under negative pressure. The gas in the external environment is discharged into the dust collection chamber 23 through multiple dust collection hoods 2, air duct 4 and air inlet pipe 6, so that the dust-laden airflow flows into the dust collection chamber 23. The dust-laden airflow is then dispersed and flows into the two mounting shells 7. The dust-laden airflow comes into contact with the surface of multiple spirally surrounding fan-shaped plates 12. Due to their large mass, the large dust particles in the dust-laden airflow are impacted by inertia onto the surface of the multiple fan-shaped plates 12, so that the large dust particles are discharged into the bottom surface of the dust collection chamber 23.

[0021] The dust collection chamber 23 is equipped with two filter boxes 24 inside. The dust collection chamber 23 is completely sealed. The door and body of the dust collection chamber 23 are sealed with rubber sealing gaskets.

[0022] The outer surfaces of the two filter boxes 24 and the interior of the dust collection chamber 23 are connected by a sealing plate. The bottom part of the dust collection chamber 23 is sealed by the sealing plate. The sealing plate is set at the gap between the two filter boxes 24 and the interior of the dust collection chamber 23. At the same time, the contact surfaces of the sealing plate with the interior of the dust collection chamber 23 and the exterior of the filter boxes 24 are sealed by sealant or rubber gaskets, so that the bottom space of the dust collection chamber 23 and the interior of the two filter boxes 24 are connected, and the airflow flows stably through the bottom space of the dust collection chamber 23 to the interior of the two filter boxes 24. The surface of the sealing plate has a through hole for the square rod 18 to pass through. A pipe is installed in the through hole, and the square rod 18 is inserted into the piston tube. The surface of the square rod 18 is tightly fitted with a piston block. The piston block is slidably sealed with the interior of the square tube, which facilitates the reciprocating movement of the square rod 18.

[0023] A spraying mechanism 5 is provided above the two filter boxes 24. The spraying mechanism 5 includes a spray box 19, which is installed inside the dust collection chamber 23. The spray box 19 is located above the two filter boxes 24. A conveying pipe 20 is provided inside the spray box 19. A conveying branch pipe is installed through the bottom of the conveying pipe 20. The bottom ends of multiple conveying branch pipes correspond to the internal positions of the two filter boxes 24. Atomizing nozzles 21 are installed at the bottom ends of multiple conveying branch pipes. One end of the conveying pipe 20 passes through the side of the spray box 19 and extends to the outside. One end of the conveying pipe 20 is connected to a submersible nozzle. Pump 22, a submersible pump, is located in the water source. After being powered on, the submersible pump 22 transports the aqueous solution in the water source to multiple atomizing nozzles 21 through the delivery pipe 20 and multiple delivery branch pipes. As the water pressure in the atomizing nozzles 21 increases, the aqueous solution in the atomizing nozzles 21 is atomized and sprayed out, forming a fine water mist. When fine dust particles are carried by the airflow around the droplets, larger particles cannot completely follow the airflow due to inertia. They will deviate from their original trajectory and collide with the droplets and be captured. The dust-laden droplets that are captured by the water and become larger settle to the bottom of the dust collection chamber 23 inside the equipment due to gravity.

[0024] Each of the two filter boxes 24 has two mesh plates 25 inside. The two mesh plates 25 allow airflow to pass through and also stabilize multiple stacked PVC multifaceted hollow spheres 9, improving the stability of the PVC multifaceted hollow spheres 9 in the filter box 24.

[0025] Between the two mesh panels 25, there are multiple stacked PVC hollow spheres 9. Each PVC hollow sphere 9 has 8-12 semi-fan-shaped blades. This design provides a large gap, facilitating gas flow. Simultaneously, the friction between the gas and the surface of the PVC hollow spheres 9 generates static electricity, which can also adsorb dust through electrostatic attraction.

[0026] The bottom of the two filter boxes 24 are equipped with mounting housings 7, which are connected to the inner cavity of the filter boxes 24. The interior of the mounting housings 7 is provided with multiple spirally arranged fan-shaped plates 12. When the dust-laden airflow flows into the two mounting housings 7 from the bottom space of the dust removal chamber 23, the dust-laden airflow will collide with the multiple fan-shaped plates 12. Large dust particles in the dust-laden airflow will impact the surface of the fan-shaped plates 12 due to inertia, causing some large dust particles to be electrostatically adsorbed at the bottom or fall off due to their large mass, which is used for preliminary filtration of dust in the dust-laden airflow.

[0027] Two mounting housings 7 are fitted with coaxially arranged mounting rods 11. Multiple sector plates 12 are spirally mounted on the sides of the two mounting rods 11. The bottom ends of the two mounting rods 11 extend to the bottom of the mounting housings 7. A square rod 18 connects the bottom ends of the two mounting rods 11. A fixing plate 17 is fitted onto the surface of the square rod 18. Both ends of the fixing plate 17 are mounted on the outside of the two filter boxes 24. A drive motor 13 is located above the square rod 18. Circular plates 14 are mounted on the movable end of the drive motor 13 and the top end of the square rod 18. The two circular plates 14... Multiple protrusions 15 arranged at equal angles are installed at both the top and bottom. Vertically, adjacent protrusions 15 are staggered. When the movable end of the drive motor 13 rotates under force, it drives the connected circular plate 14 to rotate synchronously. The circular plate 14 then drives the connected protrusions 15 to rotate synchronously. At this time, the lower circular plate 14 is in a horizontal, stationary state. As the upper circular plate 14 rotates, because the position of the drive motor 13 is fixed, the upper circular plate 14 does not change its horizontal position. The multiple protrusions 15 in the upper rotating state... 5. The upper protrusion 15 slides on the arc surface of the multiple protrusions 15 below it. The sliding trajectory is such that when the upper protrusion 15 is rotated under force, the bottom end of the upper protrusion 15 and the bottom end of the lower protrusion 15 are on the same horizontal plane. After being subjected to force, the bottom end of the upper protrusion 15 slides along the arc surface of the lower protrusion 15. The upper protrusion 15 applies a torque force to the lower protrusion 15 and also applies a vertical force to it. The square rod 18, due to its own shape and structure, and the fixing plate 17 having openings for the square rod, The square hole of the 18-part fitting prevents the square rod 18 from rotating on the fixed plate 17 after being subjected to force. When the bottom end of the upper protrusion 15 slides to the top end of the lower protrusion 15, the protrusion 15 is subjected to force and pushes the lower circular plate 14 to move downward. The lower circular plate 14 pushes the square rod 18 to slide synchronously in the square hole of the fixed plate 17. At the same time, the lower circular plate 14 applies pressure to the compression spring 16. At this time, the square rod 18 pulls down the two mounting rods 11 through the connecting rod 10. The two mounting rods 11 drive multiple sector plates 12 to move downward synchronously.As the bottom end of the upper protrusion 15 continues to rotate, the bottom end of the upper protrusion 15 separates from the top end of the lower protrusion 15. At this time, the lower circular plate 14 is not affected by external force. Through the elastic potential energy of the compression spring 16, it pushes the lower circular plate 14 upward. The lower circular plate 14 pushes the protrusion 15 connected to it to slide along the arc surface of the upper protrusion 15. With the continuous operation of the drive motor 13, it facilitates the continuous downward and downward reciprocating motion of the lower circular plate 14, so that the lower circular plate 14 drives the square rod 18 to reciprocate synchronously, and then through the connecting rod 1 The zero-transmitted torque drives two mounting rods 11 to reciprocate synchronously. These rods, in turn, drive multiple sector plates 12 within the two mounting housings 7 to reciprocate synchronously. This vibration causes most of the dust particles attached to the bottom of the sector plates 12 to be dislodged, facilitating the cleaning of dust adhering to the plates. During continuous long-term operation, the vibration of the sector plates 12 can be intermittently controlled to clean the dust adhering to their bottoms, allowing them to continue blocking dust particles and improving the initial dust treatment effect over extended periods.

[0028] The fixed plate 17 and one of the circular plates 14 are elastically connected. A compression spring 16 is sleeved on the surface of the square rod 18. The two ends of the compression spring 16 are respectively installed on the surface of the fixed plate 17 and one of the circular plates 14. When one of the circular plates 14 moves downward, the compression spring 16 is compressed after being subjected to force. At this time, the compression spring 16 is in an energy storage state. When one of the circular plates 14 is not subjected to external force, the compression spring 16 pushes one of the circular plates 14 upward through elastic potential energy, so that one of the circular plates 14 can be reset.

[0029] A connecting rod 10 is connected between the bottom ends of the two mounting rods 11. The bottom end of the square rod 18 is mounted on the surface of the connecting rod 10. The connecting rod 10 is used to connect the square rod 18 and the two mounting rods 11, so that the force on the square rod 18 can be synchronously transmitted to the two mounting rods 11, enabling the two mounting rods 11 to move stably under force.

[0030] The exhaust port of the fan 3 is connected to the demisting box 1 through a pipe. The demisting box 1 consists of a box body, a box cover, and a desiccant built into the box body. The box body and the box cover are sealed together and opened and closed by multiple buckles. The desiccant is used to absorb the aqueous solution in the airflow, improve the dryness of the gas discharged into the external environment, and maintain the working environment around the equipment.

[0031] In this scheme, a drain port 8 is provided at the bottom of the dust removal chamber 23. One end of the drain port 8 is connected to a valve, and the dust-containing aqueous solution accumulated in the dust removal chamber 23 can be conveniently discharged from the dust removal chamber 23 by opening and closing the valve.

[0032] Working principle: During dust removal operation, the fan 3 is first powered on. The fan 3 drives the airflow in the dust removal chamber 23 and the two filter boxes 24 to circulate. The airflow carrying dust passes through multiple dust suction hoods 2, air ducts 4 and air inlet pipes 6 and is discharged into the bottom space of the dust removal chamber 23. The dust-laden airflow is then transported to the dust removal chamber 23 and dispersed into the two mounting shells 7. The dust-laden airflow collides with multiple fan-shaped plates 12. Large dust particles in the dust-laden airflow will impact the surface of the fan-shaped plates 12 due to inertia. Some of the large dust particles are attracted to the bottom due to electrostatic adsorption or fall off due to their large mass, which is used for preliminary filtration of dust in the dust-laden airflow.

[0033] After preliminary filtration, the dust-laden airflow is transported to the filter box 24. The dust-laden airflow flows through the gaps of multiple PVC multi-faceted hollow spheres 9 and generates static electricity by friction on their surfaces. Dust is adsorbed by electrostatic adsorption and used to filter the dust in the dust-laden airflow again.

[0034] At the same time as the fan 3 starts, the submersible pump 22 is powered on synchronously. The submersible pump 22 delivers the aqueous solution from the water source to the inner cavity of the two filter boxes 24 through multiple nozzles 21. The water mist sprayed from the multiple nozzles 21 can adsorb the dust in the airflow in the filter box. The dust-laden droplets captured by the water agglomerate and become larger. Due to gravity, they settle to the bottom of the dust removal chamber 23 inside the equipment, thus filtering the dust three times.

[0035] Some of the water mist is transported by the fan 3 through two exhaust branch pipes, the exhaust main pipe and the fan 3 to the demister box 1, and then discharged into the external environment after being dried in the demister box 1.
