Description

Technical Field

[0001] The present invention relates to the technical field of Venturi scrubbing equipment, and in particular to a Venturi scrubber capable of adjusting its shape. Background Art

[0002] A Venturi scrubber is a wet pollution control device used to remove particulate matter and gaseous pollutants from industrial waste gas. It operates on the principle of the Venturi effect. Dust-laden gas enters the inlet section of the Venturi scrubber and is then accelerated in the contracting portion of the Venturi throat. According to the Venturi effect, the pressure of the fluid decreases as it passes through the contracting portion of the pipe, generating a high-speed airflow.

[0003] The currently used Venturi scrubber adopts the method of spraying in the middle to diffuse water into the exhaust gas for humidification, weighting and dust removal. It has a fixed shape and is inconvenient to adjust the middle part of the Venturi tube as needed to finely control the amplitude of the Venturi effect.

[0031] Install the scrubber indoors or in a factory building, and connect the reduction pipe 101 to the exhaust gas source to ensure continuous input of exhaust gas. Pre-fill water in the water supply tank 11, seal the water injection hole with a threaded plug after adding water, and then open the replenishment ball valve 603 to automatically replenish water to the circulating water tank 6; You can choose to use a water pump instead of the replenishing ball valve 603, set a water level sensor in the circulating water tank 6, and use the water pump to input water when the water level drops; Different types of core modules 2 are pre-made, such as a solid module for enclosing the Venturi core 1; a module with a tapered hole in the middle can reduce the air passing area and increase the pressure; a module with a conventional round hole in the middle maintains the original pressure; the core module 2 is automatically locked by the self-locking block 106. When installing a new module, the new module can be used to push the original module away to achieve switching, and the self-locking block 106 can automatically position.

[0032] Water Delivery and Control: Start the pump motor 806 to drive the transmission wheel 807 to rotate, thereby causing the cross hinge seat 804 eccentrically connected to the rear end of the transmission wheel 807 to rotate circumferentially, driving the four groups of delivery pistons 802 to perform intermittent piston movement, producing a delivery variable volume effect, and cooperating with the two groups of one-way valves 803 to extract water from the rear external connecting pipe 808 and input it into the front external connecting pipe 808; the water in the rear external connecting pipe 808 is reduced to generate negative pressure, and the water in the circulating water tank 6 is automatically sucked in to replenish; after the front external connecting pipe 808 is pressurized, the excess water passes through the front control ball valve 809 and is input into the atomizing nozzle 104 for spraying, or passes through the rear control ball valve 810 and enters the inner spray ring 303 for spraying. The front control ball valve 809 and the rear control ball valve 810 can be opened as needed to achieve dust removal at different positions; Electromagnet 902 controls the opening and closing of electromagnetic double-tube valve 9. When energized, it attracts T-shaped valve core 901 to open electromagnetic double-tube valve 9. When electromagnetic double-tube valve 9 connected to heating channel 10 is opened, water flows through heating channel 10 and is rapidly heated by the resistance heater within the channel, spraying out hot water to remove dust. The hot water is atomized into finer particles, which can enhance dust removal and sterilization effects. Example 2: Waste gas treatment and water circulation; The air passes through the contracting tube 101 and expanding tube 102, creating a Venturi effect, accelerating and mixing with water. The mixed water then enters the separation chamber 3. The dust-removed air is discharged from the clean air outlet 301, and the water mixed with sand flows into the sedimentation chamber 4 through the downpipe 302 below. The water naturally settles in the sedimentation chamber 4, and the dust and sand sink into the sediment pipe 401. After a certain period of accumulation, the mud discharge motor 404 is started to drive the screw propeller 403 to rotate, and the dust or mud is discharged from the mud outlet 402. Example 3: The water pipe 701 and the connecting pipe 702 form a communicating vessel. If there is no water in the water pipe 701 and the communicating pipe 702, first close the regulating ball valve 602 and the replenishing ball valve 603, pump water into the circulating water tank 6 to reduce the pressure, and use the negative pressure to pump water from the settling chamber 4 and fill the communicating vessel. The annular floating seat 5 floats inside the sedimentation bin 4 by means of water buoyancy, and the water in the sedimentation bin 4 passes through the filter cover 501, the water pipe 701 and the connecting pipe 702 and flows back to the circulating water tank 6 for recycling.

[0033] Specific usage and function of this embodiment: In the present invention, the shrink tube 101 is connected to the exhaust gas source to continuously input the exhaust gas; In the water supply tank 11, water is pre-filled, the water injection hole is sealed with a threaded plug after water is added, and then the replenishment ball valve 603 is opened, and water is automatically replenished into the circulating water tank 6; Different types of core modules 2 are pre-made, such as solid core modules 2, which can enclose the Venturi core 1. A core module 2 with a tapered hole in the middle can be selected to further reduce the air passage area to increase the pressure, or a core module 2 with a conventional round hole in the middle can be used to maintain the original pressure. The core module 2 is automatically locked by the self-locking block 106. When another set of core modules 2 is installed, the core module 2 can be used to push the original core module 2 away to switch. The self-locking block 106 can automatically position. The pump motor 806 is started to drive the transmission wheel 807 to rotate, and the transmission wheel 807 drives the cross hinge seat 804 eccentrically connected at its rear end to rotate circumferentially, thereby driving the four groups of delivery pistons 802 to intermittent piston movement, producing a delivery variable volume effect, and cooperating with the two groups of one-way valves 803 to extract water from the rear external connecting pipe 808 and input the water into the front external connecting pipe 808; when the water in the rear external connecting pipe 808 is reduced, negative pressure is generated and the water in the circulating water tank 6 is automatically sucked in for replenishment; after the front external connecting pipe 808 is pressurized, the excess water passes through the front control ball valve 809 and is input into the atomizing nozzle 104, sprayed from the atomizing nozzle 104, and passes through the rear control ball valve 810 The water enters the inner spray ring 303 and is sprayed out from the inner spray ring 303; the front control ball valve 809 and the rear control ball valve 810 can be opened as needed to realize dust removal from different positions; the electromagnet 902 can control the opening and closing of the electromagnetic double-tube valve 9. When the electromagnet 902 is energized, the T-shaped valve core 901 is attracted to open the electromagnetic double-tube valve 9, allowing water to pass through the external connecting pipe 808; for example, the electromagnetic double-tube valve 9 connected to the heating channel 10 can be opened to allow water to pass through the heating channel 10. A resistance heater is set in the heating channel 10 to quickly heat the water, and then hot water is sprayed out to remove dust. After being sprayed, the hot water is easily atomized into finer particles, which improves the dust removal effect and can also provide sterilization and other effects; The air passes through the contraction tube 101 and the expansion tube 102, generating a Venturi effect, accelerating the air and mixing it with water. The mixed water then enters the separation chamber 3. The dust-removed air is discharged from the clean air outlet 301, and the water mixed with sand flows from the downpipe 302 below into the sedimentation chamber 4. After entering the sedimentation chamber 4, the water naturally settles, and the dust and sand naturally sink and fall into the sediment pipe 401. After a certain period of time, the mud discharge motor 404 can be started to drive the screw propeller 403 to rotate, pushing the dust or mud to be discharged from the mud outlet 402; The water pipe 701 and the connecting pipe 702 form a communicating vessel. The annular floating seat 5 automatically floats inside the sedimentation chamber 4 due to the buoyancy of the water. The water inside the sedimentation chamber 4 flows through the filter cover 501, the water pipe 701 and the connecting pipe 702 and flows back to the circulating water tank 6 for continuous use. If there is no water in the water pipe 701 and the connecting pipe 702, you can first close the regulating ball valve 602 and the replenishing ball valve 603. After pumping water in the circulating water tank 6, the pressure will drop, and the water in the sedimentation tank 4 will be pumped out with the negative pressure, so that the water will fill the water pipe 701 and the connecting pipe 702 to form a communicating vessel.
