Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, in particular to an intelligent Venturi wet dust collector device. Background Art

[0002] When the Venturi wet dust collector is working, dust-laden gas enters the device from the air inlet pipe, while water is sprayed in from the throat entrance of the Venturi tube in the air inlet pipe. It is broken up by the high-speed flue gas flow, forming a large number of tiny water droplets. These water droplets move relative to the fly ash in the flue gas. Due to inertial collision and other effects, the ash particles adhere to the water droplets, forming larger ash-water droplets. Subsequently, in the diffuser of the Venturi tube, the air flow velocity gradually decreases and the pressure increases, causing the kinetic energy of the ash particles to be partially converted into pressure energy. Finally, the ash particles enter the droplet collector for sedimentation.

[0003] It is worth noting that when faced with certain sticky dusts, these dusts are often more difficult to be wetted and evenly dispersed by ordinary water. To overcome this problem, the existing technology has introduced a pre-spraying treatment process. Through pre-spraying, these sticky dusts can be more easily captured and effectively removed by subsequent dust removal equipment. However, the control of the water volume of the pre-spraying is crucial. It must be finely adjusted according to the wind speed and dust content under specific working conditions to ensure that the water volume is appropriate. Too much water will not only cause water accumulation inside the dust removal equipment, increase the burden on the equipment, but also increase unnecessary energy consumption and weaken the dust removal efficiency. Too little water will make it difficult to achieve the expected pre-spraying effect, affecting the overall performance of the dust removal.

[0004] What is even more complicated is that in the actual working process, the dust content and dust viscosity in the dust-laden gas at a certain wind speed often show dynamic fluctuations. This requires operators to pay close attention to changes in working conditions and flexibly adjust the pre-spray water volume to ensure that the dust collector always maintains the best working condition and achieves efficient and stable dust removal effects. This requires a high level of professionalism from the operators and is relatively troublesome. For this reason, we propose an intelligent Venturi wet dust collector equipment.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: an intelligent Venturi wet dust collector device, comprising an air intake pipe 1 and a pre-spray nozzle 11 installed in the air intake pipe 1, and also comprising:

[0037] The valve assembly 2 is provided on the air inlet pipe 1 and connected to the pre-spray nozzle 11, and is used to adjust the water output of the pre-spray nozzle 11;

[0038] A plurality of spiral guide blades 3 are evenly arranged in the air inlet pipe 1 and are designed to spirally guide the dust-laden gas and cause it to move forward in a rotating manner;

[0039] The inner tube 4 is rotatably arranged in the air intake pipe 1;

[0040] The transmission member 5 is provided on the air inlet pipe 1, and the valve assembly 2 is connected to the inner tube 4 via the transmission member 5, and is used to drive the valve assembly 2 to perform corresponding adjustment work when the rotating and forward dust-laden gas utilizes the viscosity of the dust to rub the inner tube 4 and drive the inner tube 4 to rotate;

[0041] Specifically, when the dust-laden gas enters the air intake pipe 1, the device effectively guides the exhaust gas to rotate forward through the spiral guide blades 3. During this process, the dust content and viscosity in the exhaust gas directly affect the adhesion to the inner tube 4: the more dust or the greater the viscosity, the stronger the adhesion to the inner tube 4, and the greater the rotation angle. It is worth noting that the rotation of the inner tube 4 will link the transmission part 5, automatically adjust the valve assembly 2 to flexibly control the size of the pre-spray nozzle 11, without the need for human intervention, showing a highly intelligent feature.

[0042] The valve assembly 2 includes a water pipe 21 which is conductively connected to the pre-spray nozzle 11. A hollow cylinder 22 is conductively connected to the water pipe 21. A rotating cylinder 23 is rotatably connected inside the hollow cylinder. A through hole 24 is provided on the rotating cylinder 23, and one end of the rotating cylinder 23 is fixedly connected to a shaft 25. The shaft 25 is rotatably connected to the air inlet pipe 1 through a bearing, and is used to drive the rotating cylinder 23 to rotate. The amount of water in the pre-spray nozzle 11 is adjusted by rotating the rotating cylinder 23 through the rotating shaft 25.

[0043] The transmission member 5 includes a toothed disc 26 fixedly connected to one end of the shaft 25. A plurality of tooth protrusions 27 that mesh with the toothed disc 26 are evenly and evenly fixedly connected to the inner tube 4. A torsion spring 28 is sleeved on the shaft 25. The two ends of the torsion spring 28 are respectively fixedly connected to the shaft 25 and the intake pipe 1. Rotating the inner tube 4 drives the shaft 25 to rotate. At the same time, the torsion spring 28 is twisted to provide a self-restoring elastic force.

[0044] Specifically, the torsion spring 28 provides resistance for the rotating cylinder 23. When the dust content or dust viscosity is higher, the force driving the inner tube 4 to rotate is greater at the same wind speed, thereby increasing the water volume of the pre-spray nozzle 11.

[0045] Multiple bleed air pipes 29 are evenly and evenly connected to the intake pipe 1. A circular ring 31 is slidably connected to the intake pipe 1. The circular ring 31 is connected to multiple spiral guide vanes 3. An electric push rod 32 is fixedly connected to the intake pipe 1. The extended end of the electric push rod 32 is fixedly connected to the circular ring 31, which is used to drive the spiral guide vanes 3 to move across the area of ​​the inner pipe 4 and simultaneously open the multiple bleed air pipes 29 to draw air to flush the inner pipe 4.

[0046] Specifically, the dust-laden gas will rotate and generate centrifugal force when passing through the spiral guide blades 3, thereby throwing the dust in the gas toward the inner wall of the intake pipe 1, so as to better fit the inner tube 4 to drive the inner tube 4 to rotate. Then, when the inner wall of the inner tube 4 needs to be cleaned, the dust-laden gas does not need to rotate, thereby first driving the spiral guide blades 3 to move across the inner tube 4 area, and then connecting the air duct 29 to the intake pipe 1, so that clean air from the outside is sucked into the intake pipe 1 and moves along the pipe wall to flush and clean the inner tube 4, thereby improving the accuracy of detection.

[0047] A ring body 33 is fixedly connected between the multiple spiral guide blades 3 to improve the stability of the device. A rectangular plate 34 is fixedly connected to one end of the spiral guide blade 3, and a magnet block 35 is fixedly connected to one end of the rectangular plate 34. A sliding groove 36 is opened on the inner wall of the intake pipe 1, and one end of the magnet block 35 is located in the sliding groove 36 and is slidably connected to the inner wall of the intake pipe 1.

[0048] A magnet block 35 is also fixedly connected to the circular ring 31. A chute 36 is also provided on the outer wall of the intake pipe 1. One end of the magnet block 35 is located in the chute 36 and is slidably connected to the inner wall of the chute. The magnet block 35 on the circular ring 31 is correspondingly adsorbed and connected to the magnet block 35 on the rectangular plate 34, so as to drive the spiral guide blade 3 to move when the circular ring 31 is moved.

[0049] During specific use, the electric push rod 32 is started to drive the ring 1 31 to move, and then the magnet block 35 cooperates to drive the multiple spiral guide blades 3 to move.

[0050] A cross tube 37 is connected to the air bleed pipe 29, and a sliding cylinder 38 is slidably connected inside the cross tube 37. An air hole 39 is opened on the sliding cylinder 38, and a guide rod 41 is fixedly connected to one end of the sliding cylinder 38. The guide rod 41 is slidably connected to the intake pipe 1, and a spring 42 is sleeved on the guide rod 41. The two ends of the spring 42 are respectively in contact with the sliding cylinder 38 and the intake pipe 1, pushing the sliding cylinder 38 to make the air hole 39 connect to the air bleed pipe 29. At the same time, the spring 42 is compressed and contracts to provide it with self-restoring elastic force.

[0051] Ring 1 31 is rotatably connected to ring 2 43, and multiple triangular blocks 44 are fixedly connected to ring 2 43. A linkage part 45 is provided between the electric push rod 32 and ring 2 43, which is used to continue to start the electric push rod 32 after ring 1 31 moves into place to drive ring 2 43 to rotate relative to ring 1 31, thereby driving multiple triangular blocks 44 to push multiple sliding cylinders 38 in sequence.

[0052] The linkage member 45 includes a mounting plate 46 fixedly connected to the circular ring 31. A hollow shaft 47 is rotatably connected to the mounting plate 46 via a bearing. A toothed disc 48 is fixedly connected to the hollow shaft 47. A plurality of tooth grooves 49 are evenly spaced on the circular ring 43 and mesh with the toothed disc 48.

[0053] A circular plate 51 is fixedly connected to the electric push rod 32. A tension spring 52 is fixedly connected between the circular plate 51 and the mounting plate 46, which is used to drive the ring 1 31 to move when the electric push rod 32 is started. A sliding post 53 is slidably connected within the hollow shaft 2 47. The extended end of the electric push rod 32 is fixed to the sliding post 53, and a spiral groove 54 is formed on the sliding post 53. A cylindrical protrusion 55 with one end located in the spiral groove 54 is fixedly connected to the hollow shaft 2 47.

[0054] Specifically, the electric push rod 32 is started to use the tension spring 52 to pull the ring 1 31 to move, thereby driving the spiral guide blade 3 to move. When it moves into place, the electric push rod 32 is continued to be started to drive the tension spring 52 to extend, and at the same time drive the sliding column 53 to move, and then use the spiral groove 54 to drive the cylindrical protrusion 55 and the hollow shaft 2 47 to rotate, and then drive the gear disk 2 48 to rotate, thereby driving the ring 2 43 to rotate, and then drive multiple triangular blocks 44 to push multiple sliding cylinders 38 in turn, so that multiple air ducts 29 are opened separately in turn to improve the cleaning effect.

One side of the friction plate 57 adopts an arc-shaped design. After the friction plate 57 is moved, it is pressed against the circular plate 56 to lock the shaft 1, thereby ensuring the stability of the pre-spray nozzle 11 when cleaning the inner tube 4.

[0057] A synchronizer 58 is provided between the circular ring 1 31 and the friction plate 57 , and the movable circular ring 1 31 drives the friction plate 57 to move by utilizing the synchronizer 58 .

[0059] Specifically, when the circular ring 31 moves, the strip plate 62 is driven to move, thereby using the inclined guide groove 63 to push the sliding column 61 to move, and then driving the arc portion of the friction plate 57 to press against the circular plate 56 to lock the shaft 25.
