Description

Technical Field

[0001] The 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, and water is sprayed in from the throat entrance of the Venturi tube in the air inlet pipe, and is broken by the high-speed flue gas flow to form 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, and then form larger ash water droplets. Subsequently, in the diffuser of the Venturi tube, the air flow velocity gradually decreases and the pressure increases, so that the kinetic energy of the ash particles is partially converted into pressure energy, and finally the ash particles enter the droplet collector for sedimentation;

[0003] It is worth noting that when facing some dust with high viscosity, it is often more difficult to be wetted and evenly dispersed by ordinary water. In order to overcome this problem, the prior art introduces a pre-spraying treatment link. 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 very important. It must be finely adjusted according to the wind speed and dust content under specific working conditions to ensure that the water volume is moderate. 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, while weakening the dust removal efficiency; while 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 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 the characteristics of 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 state 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 be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0037] The valve assembly 2 is arranged 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] An inner tube 4 is rotatably disposed in the air intake pipe 1;

[0040] The transmission member 5 is arranged on the air inlet pipe 1, and the valve assembly 2 is connected to the inner tube 4 through the transmission member 5, and is used to drive the valve assembly 2 to perform corresponding adjustment work when the rotating and advancing 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 adjusting the valve assembly 2 to flexibly control the size of the pre-spray nozzle 11 without manual 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, and 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 a shaft 25 is fixedly connected to one end of the rotating cylinder 23. 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.

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

[0045] The intake pipe 1 is evenly and evenly connected with a plurality of air ducts 29, the intake pipe 1 is slidably connected with a circular ring 31, the circular ring 31 is connected with a plurality of spiral guide blades 3, and the intake pipe 1 is fixedly connected with an electric push rod 32, the extended end of the electric push rod 32 is fixedly connected with the circular ring 31, and is used to drive the spiral guide blade 3 to move to cross the inner pipe 4 area and open the plurality of air ducts 29 at the same time, so as to inhale 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 the 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 the detection.

[0049] When in 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 plurality of spiral guide blades 3 to move.

The two ends of the spring 42 are respectively in contact with the sliding cylinder 38 and the air intake pipe 1, and the sliding cylinder 38 is pushed to make the air hole 39 connect to the air duct 29. At the same time, the spring 42 is compressed and contracts to provide it with self-restoring elastic force.

[0051] A second ring 43 is rotatably connected to the first ring 31, and a plurality of triangular blocks 44 are fixedly connected to the second ring 43.

[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 toothed 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, thereby improving the cleaning effect.
