Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, in particular to a multifunctional wet dust removal device. Background Art

[0002] A wet dust collector is a device that brings dust-laden gas into close contact with a liquid (usually water), and utilizes the inertial collision of water droplets and particles, or the full mixing of water and dust, and other effects to capture particles or enlarge them or retain them in a fixed container to achieve the effect of separating water and dust.

[0003] Wet dust collectors include spray dust collectors, Venturi dust collectors, cyclone water film dust collectors and self-excited dust collectors. Among them, the working principle of the Venturi dust collector is that after the dust-laden gas enters the Venturi tube, it first passes through the contraction tube, and the air flow velocity gradually increases; it reaches the highest velocity at the throat, forming a negative pressure, sucking in the liquid and atomizing it into extremely small droplets, which fully contact the dust particles in the high-speed airflow, and combine the dust particles and droplets through inertial collision, interception, diffusion and other effects; then the gas enters the diffusion tube, the velocity decreases, and the pressure rises. The combined dust droplets are separated and captured under the action of gravity, centrifugal force, etc.

[0004] However, existing Venturi dust collectors suffer from numerous problems. First, the throat size is fixed, making it difficult to flexibly adjust when handling dust-laden gases of varying flow rates and concentrations. This results in excessive energy consumption at low flow rates and reduced dust removal efficiency at high flow rates. Second, the intense mixing of gas and liquid in the throat easily leads to scaling and clogging, impacting normal operation and making cleaning and maintenance difficult. Third, the liquid atomization effect is significantly affected by fluctuations in gas flow, making it difficult to ensure stable dust removal. Summary of the Invention

[0026] The following is combined with Figure 1-6 This application is described in further detail.

[0027] The present application discloses a multifunctional wet dust removal device, referring to Figure 1 , including a separator and a venturi tube connected to the separator inlet, the separator includes a cylinder 1 connected to the venturi tube and a box cover 2 connected to the side wall of the cylinder 1, one end of the box cover 2 is rotatably connected to the cylinder 1 through a vertically arranged rotating shaft, and the other end is fixed by a snap-fit ​​structure, which facilitates internal maintenance and equipment replacement after the box cover 2 is opened.

[0028] Reference Figure 1 The bottom and top of the cylinder 1 are conical structures, which facilitate the outflow of impurities and the discharge of filtered gas. The bottom of the cylinder 1 is equipped with filtered water, which is used for dust removal on the one hand and acts as a water seal on the other hand to prevent gas from overflowing from the bottom of the cylinder 1.

[0029] Reference Figure 1 and Figure 2The venturi tube includes a contraction tube 3, a throat tube 4 and a diffusion tube 5 from the feed end to the discharge end. The contraction tube 3 is connected to a water inlet pipe 6. When the gas enters the separator through the venturi tube, the Bernoulli principle is used to make the water in the water inlet pipe 6 enter the venturi tube.

[0030] Reference Figure 1 and Figure 2 The throat pipe 4 includes an inner tube 7 and connecting plates 8 connected to both ends of the inner tube 7. The connecting plates 8 are respectively threadedly connected to the contraction tube 3 and the diffusion tube 5 to facilitate the disassembly of the throat pipe 4. The inner tube 7 is made of elastic material, and can be made of latex. A plurality of strip through holes are opened axially on the inner tube 7, and the plurality of strip through holes are evenly distributed circumferentially along the inner tube 7. The throat pipe 4 also includes an adjusting slider 9 arranged at the position of the strip through hole. The adjusting slider 9 is inserted into the corresponding strip through hole, and the inner tube 7 is fixed and sealed on the adjusting slider 9.

[0031] Reference Figure 2 、 Figure 3 and Figure 4 A control mechanism is provided on the connecting disk 8 to control the radial movement of the adjusting slider 9 along the inner tube 7. By making the adjusting slider 9 move along the radial direction of the inner tube 7, the inner tube 7 connected to the adjusting slider 9 is driven to retract or expand, thereby changing the diameter of the inner tube 7 and controlling the flow of the gas. The cam 13 is fixed to the cam 11 and the cam 12 is fixed to the cam 11, and the cam 13 is fixed to the cam 11, and the cam 13 is fixed to the cam 11.

[0032] Reference Figure 2 and Figure 3The adjustment slider 9 includes a mounting block 14 slidably mounted on two connecting plates 8. Mounting blocks 14 have mounting slots defined in the sidewalls of the inner tube 7. A movable block 15 is slidably mounted within the mounting slots. A control spring 16 is secured within the mounting slots, pushing the movable block 15 toward the inner tube 7. When airflow laden with impurities impacts the inner tube 7 and the movable block 15, the control spring 16 allows for fine adjustment of the movable block 15. A first ultrasonic transducer 17 is embedded within the movable block 15. The first ultrasonic transducer 17 generates ultrasonic waves with a frequency of 20-40 kHz. When the device is in operation, these waves are emitted into the throat 4, promoting more uniform mixing of the gas and liquid within the throat 4 and enhancing the collision and agglomeration of dust particles and liquid droplets. Under the influence of ultrasonic waves, smaller dust particles are more likely to combine with liquid droplets, forming larger particles that facilitate subsequent separation and further improve dust removal efficiency. Ultrasonic waves also provide a certain degree of anti-scaling effect, reducing dust adhesion to the inner wall of the throat 4.

[0033] Reference Figure 3 and Figure 4 A heating groove is provided on the end face of the movable block 15 near the axis of the inner tube 7, in which a heating element 18 is fixedly installed. The heating element 18 is a ceramic heating plate. When processing dust-laden gas containing easily condensable components or high humidity, the heating element 18 is activated to keep the surface temperature of the regulating slider 9 within a suitable range, preventing dust from condensing on the inner wall of the throat 4 due to temperature drop, avoiding blockage and ensuring the continuous and stable operation of the dust collector.

[0034] Reference Figure 4 and Figure 5 A deflection device for increasing the resistance of the exhaust gas to upward movement is installed in the cylinder 1. A filter device 19 is provided in the cylinder 1 above the deflection device. The filter device 19 includes a coarse filter, a medium filter and a fine filter installed from bottom to top. The apertures of the coarse filter, the medium filter and the fine filter increase in sequence. A number of spray heads 20 are installed in the cylinder 1 above the filter device 19. The spray heads 20 are connected to an external water pump through a water pipe. The corresponding reagents or water are sprayed into the cylinder 1 through the spray heads 20 to fully react with the gas, and the internal cleaning is facilitated by spraying water.

[0035] Reference Figure 4 and Figure 5 The deflection device includes a horizontally arranged mounting net 21, on which are fixed several inclined and parallel fixed plates 22, and a sliding frame 23 is provided on the outer cover of the fixed plate 22. A first magnet block 24 is fixed on the mounting net 21, and a second magnet block 25 adsorbed on the first magnet block 24 is fixed on the sliding frame 23. When too many impurities accumulate on the surface of the sliding frame 23, the first magnet block 24 and the second magnet block 25 separate, and the sliding frame 23 slides obliquely downward along the direction of the fixed plate 22.

[0036] Reference Figure 4 and Figure 5 Several groups of sliding grooves 10 are opened on the sliding frame 23 along the sliding direction, and sliding blocks 26 are fixed on the fixed plate 22 and penetrate into the corresponding sliding grooves 10. A scraper 27 connected to the same group of sliding blocks 26 is fixed on the sliding block 26. When the sliding frame 23 slides downward, the scraper 27 cleans the impurities on the surface of the sliding frame 23.

[0037] Reference Figure 3 A spiral guide blade 28 is provided on the inner wall of the cylinder 1, and a discharge electrode is arranged on the central axis of the spiral guide blade 28 to form a centrifugal and electrostatic coupling separation zone; a plurality of second ultrasonic transducers 29 are installed in the cylinder 1 above the spiral guide blade 28, and the plurality of second ultrasonic transducers 29 are distributed in an array to form an acoustic wave agglomeration and enhancement zone.

[0038] The dust-laden gas forms a high-speed vortex under the action of the spiral guide blades 28. The discharge electrode applies negative high voltage to form a corona discharge zone. The dust is charged and migrates to the wall. The airflow enters the acoustic agglomeration and strengthening zone. The ultrasonic wave causes the fine particles to agglomerate and grow. The droplets are intercepted and agglomerated and then flow downward.

[0039] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
