Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and in particular relates to a self-driven cyclone scrubbing tower for waste gas. Background Technology

[0002] In industrial production processes, large amounts of waste gas containing harmful substances such as dust, acidic gases, and organic pollutants need to be purified before being released into the atmosphere. As a common waste gas treatment device, the scrubbing tower effectively removes pollutants by spraying scrubbing liquid into the waste gas. It is widely used in industries such as chemical, pharmaceutical, metallurgy, and power. Currently, the main types of scrubbing towers on the market are packed towers, spray towers, and cyclone plate towers. Traditional scrubbing towers generally adopt a fixed structure. After the exhaust gas enters the scrubbing tower, it directly contacts the spray system. Due to the uneven airflow distribution, the gas-liquid contact efficiency is low, and the pollutant removal rate is difficult to meet the increasingly stringent environmental protection standards. For example, Chinese patent application number CN201310173085.9 discloses an exhaust gas scrubbing tower, including a tower body, a clean gas outlet at the top of the tower body, a wastewater tank at the bottom of the tower body, a water inlet pipe connected to one side of the bottom of the wastewater tank, an exhaust gas inlet in the middle of the bottom of the tower body, a bag filter dust collector installed inside the tower body at the exhaust gas inlet, a spray device installed above the tower body, a packing layer installed inside the tower body below the spray device, the spray device connected to the wastewater tank through a pipeline, a demisting layer installed above the spray device, and a dryer installed at the clean gas outlet above the demisting layer. However, the disadvantage of this technical solution is that no rotating guide component is installed inside the scrubbing tower. After the exhaust gas enters the scrubbing tower, it directly contacts the spray system. Due to the uneven airflow distribution, the gas-liquid contact efficiency is low, resulting in a low pollutant removal rate. Summary of the Invention

[0006] Furthermore, the spray assembly includes a lower spray pipe, one end of which extends out of the washing tower and is connected to the circulation pipe, and the other end of which is connected to the upper spray pipe through a bend. The upper spray pipe is arranged parallel above the lower spray pipe, and the lower spray pipe is fixedly connected to the upper spray pipe through a bracket.

[0008] Furthermore, the nozzle assembly includes a main nozzle pipe, which is rotatably connected to the lower spray pipe. A bearing is installed at the rotatable connection between the main nozzle pipe and the lower spray pipe. A flow channel is provided inside the main nozzle pipe, and the lower end of the insertion pipe is inserted into the flow channel. An impeller is fixed to the outside of the main nozzle pipe, and a baffle is provided inside the lower spray pipe near the impeller. A nozzle body is fixed to the lower end of the main nozzle pipe, and a liquid distribution chamber is provided inside the nozzle body. The flow channel communicates with the liquid distribution chamber.

[0009] Furthermore, the nozzle body is fixedly connected to four branch nozzles, and a telescopic hose is provided in the middle of the branch nozzle. The nozzle body is fixedly connected to one end of a fixed rod, and the other end of the fixed rod is rotatably connected to a second rotating rod.

The movable disc rotates outside the adjusting block, and the adjusting block is threadedly connected to a threaded rod. The threaded rod is fixed to the lower end of the nozzle body.

[0010] Furthermore, the demisting assembly includes a main frame, which is located inside the scrubbing tower near the gas outlet. A rectangular frame is fixed inside the main frame, and multiple baffles are fixed at equal intervals inside the rectangular frame. Four sets of sealing plate units are provided between the main frame and the rectangular frame. Each set of sealing plate units includes two sealing plates, which are fixed to the upper and lower ends of the main frame by locking bolts.

A cleaning block is fixed at the lower end of the cleaning plate and is slidably connected to an arc-shaped groove.

[0013] The advantages of this invention are: The exhaust gas enters the scrubbing tower through the exhaust gas inlet at the bottom of the tower. During its ascent, it first comes into contact with the non-powered rotating guide component, which uses the energy of the exhaust gas flow to rotate automatically, creating a high-intensity swirling flow field. The airflow then enters the spray area and comes into full contact with the scrubbing liquid sprayed by the spray component. The pollutants are captured or dissolved by the droplets. The preliminarily purified gas continues to rise and passes through the demister component to remove the entrained droplets. Finally, the clean gas is discharged from the gas outlet. The entire process achieves highly efficient purification of the exhaust gas. The non-powered rotating guide component is driven by the kinetic energy of the exhaust gas itself, eliminating the need for an additional power unit, significantly reducing operating energy consumption, while enhancing gas-liquid contact efficiency and improving pollutant removal rate.

Detailed Implementation

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] Example 1: As Figures 1-14As shown, a self-driven cyclone scrubbing tower for exhaust gas includes a scrubbing tower body 1, an exhaust gas inlet 2 at the bottom of the scrubbing tower body 1, a gas outlet 6 at the top of the scrubbing tower body 1, a non-powered rotating guide assembly 3 and a spray assembly 4 inside the scrubbing tower body 1, the spray assembly 4 being located above the non-powered rotating guide assembly 3, and a demisting assembly 5 being located inside the scrubbing tower body 1 near the gas outlet 6. The working principle of the above technical solution is as follows: the exhaust gas enters the tower from the exhaust gas inlet 2 at the bottom of the scrubbing tower 1. During the upward process, it first comes into contact with the non-powered rotating guide component 3. This component uses the energy of the exhaust gas flow to achieve automatic rotation, so that the airflow forms a high-intensity swirling field. Then the airflow enters the spray area and comes into full contact with the scrubbing liquid sprayed by the spray component 4. The pollutants are captured or dissolved by the droplets. The gas after preliminary purification continues to rise and passes through the demister component 5 to remove the entrained droplets. Finally, the clean gas is discharged from the gas outlet 6. The whole process achieves efficient purification of exhaust gas. At the same time, the non-powered rotating design greatly reduces energy consumption.

[0018] Example 2: Figures 1-14 As shown, a spray water tank 7 is fixed on the side of the washing tower body 1. The washing tower body 1 is connected to the spray water tank 7. The spray water tank 7 is connected to the spray assembly 4 through the circulation pipe 9. The circulation pipe 9 is equipped with a circulation spray pump 8 and a regulating valve 10. The working principle of the above technical solution is as follows: the spray tank 7 collects the washing liquid at the bottom of the washing tower 1 and delivers it to the spray assembly 4 through the circulation pipe 9 driven by the circulation spray pump 8. The regulating valve 10 precisely controls the flow rate of the circulating liquid to adapt to different working conditions. This circulation system realizes the reuse of washing liquid and reduces operating costs. The design of the spray tank 7 being directly connected to the washing tower 1 ensures smooth liquid return and avoids clogging problems.

[0019] Example 3: Figures 1-14 As shown, the non-powered rotating flow guide assembly 3 includes an annular support 301, which is fixedly connected to one end of a plurality of swirl plates 302. The other ends of the plurality of swirl plates 302 are all fixed on a fixed disc 303. A track 304 is provided on the outside of the annular support 301. The washing tower body 1 is rotatably connected to a roller 305 through a roller support. The roller 305 is in rolling contact with the track 304. The working principle of the above technical solution is as follows: When the unpowered rotating guide component 3 is working, the upward exhaust gas impacts the inclined surface of the swirl plate 302, generating a tangential force to push the annular support 301 to rotate along the track 304. The roller 305 supports the annular support 301 and greatly reduces the rotational resistance, enabling the component to start rotating at low flow rates. The high-speed rotating swirl plate 302 not only extends the airflow path but also generates a centrifugal force field, enhancing the collision frequency and intensity of the exhaust gas and subsequent spray droplets, significantly improving the pollutant removal efficiency. The fixed disk 303 ensures stable airflow in the central area and avoids the formation of vortex dead zones.

[0020] Example 4: Figures 1-14 As shown, the spray assembly 4 includes a lower spray pipe 401, one end of which extends out of the washing tower body 1 and is connected to the circulation pipe 9. The other end of the lower spray pipe 401 is connected to the upper spray pipe 402 through a bend. The upper spray pipe 402 is arranged parallel above the lower spray pipe 401. The lower spray pipe 401 is fixedly connected to the upper spray pipe 402 through a bracket 404. The end of the upper spray pipe 402 is in a closed state. Multiple nozzle assemblies are rotatably connected inside the lower spray pipe 401. A bearing 407 is provided at the rotatable connection between the nozzle assembly and the lower spray pipe 401. A plug pipe 403 is fixed at the lower end of the upper spray pipe 402. The lower end of the plug pipe 403 is inserted into the nozzle assembly. A baffle 419 is provided inside the lower spray pipe 401 near the nozzle assembly. The working principle of the above technical solution is as follows: When the spray assembly 4 is working, the washing liquid enters the lower spray pipe 401 through the circulation pipe 9, and then flows into the upper spray pipe 402 through the bend pipe. The insertion pipe 403 guides the liquid in the upper spray pipe 402 into the rotating nozzle assembly below. The presence of the baffle 419 causes the fluid to concentrate and impact the impeller 408, enhancing the rotational driving force. The bracket 404 ensures a stable connection between the upper and lower pipes and withstands the internal fluid pressure and vibration. This design achieves full coverage of the spray area, and the rotational movement of the nozzle assembly makes the washing liquid distribution more uniform, avoids the formation of local dry areas, and improves washing efficiency.

[0021] Example 5: Figures 1-14 As shown, the nozzle assembly includes a nozzle main pipe 405, which is rotatably connected to the spray lower pipe 401. A bearing 407 is disposed at the rotatable connection between the nozzle main pipe 405 and the spray lower pipe 401. A flow channel 406 is provided inside the nozzle main pipe 405. The lower end of the insertion pipe 403 is inserted into the flow channel 406. A rotary sealing structure is provided between the insertion pipe 403 and the flow channel 406. An impeller 408 is fixed on the outside of the nozzle main pipe 405. A baffle 419 is provided inside the spray lower pipe 401 near the impeller 408. A nozzle body 418 is fixed at the lower end of the nozzle main pipe 405. A liquid distribution chamber 409 is provided inside the nozzle body 418. The flow channel 406 communicates with the liquid distribution chamber 409. The nozzle body 418 is fixedly connected to four branch nozzles 410. A telescopic hose 411 is provided in the middle of the branch nozzles 410. The nozzle body 418 is fixedly connected to one end of a fixed rod 417. The other end of the fixed rod 417 is rotatably connected to a rotating rod 416. The end of the rotating rod 416 is slidably connected to the branch nozzles 410. The rotating rod 416 is rotatably connected to the upper end of a rotating rod 415. The lower end of the rotating rod 415 is rotatably connected to a moving disk 414. The moving disk 414 rotates outside the adjusting block 413. The adjusting block 413 is threadedly connected to a threaded rod 412. The threaded rod 412 is fixed to the lower end of the nozzle body 418. The working principle of the above technical solution is as follows: When the spray assembly 4 is working, the washing liquid enters the lower spray pipe 401 through the circulation pipe 9. Under the action of the baffle 419, the washing liquid concentrates and impacts the impeller 408, causing the impeller 408 to rotate and the entire nozzle assembly to rotate at high speed. The bearing 407 ensures smooth rotation. The washing liquid flows into the upper spray pipe 402 through the bend pipe. The insertion pipe 403 guides the spray liquid in the upper spray pipe 402 into the flow channel 406. After flowing through the liquid distribution chamber 409, it enters the branch spray pipe 410 and is sprayed out, thereby realizing the rotational spraying of the spray liquid, enhancing the collision frequency and intensity of the exhaust gas and the spray droplets, and significantly improving the pollutant removal efficiency. When the regulating mechanism is working, when the system stops working, the worker can enter the scrubbing tower 1 and rotate the regulating block 413. The regulating block 413 rotates with the threaded rod 412, causing the regulating block 413 to move up and down. The moving disc 414 moves up and down, driving the linkage of rotating rod 1 415 and rotating rod 2 416. This causes rotating rod 2 416 to rotate with the fixed rod 417, changing the opening and closing angle of the branch spray pipe 410. The telescopic hose 411 ensures that the liquid flow is not affected. This design can change the spray range and optimize the spray mode according to the concentration and distribution characteristics of pollutants in the exhaust gas, saving water and improving purification efficiency.

[0022] Example 6: Figures 1-14 As shown, the demisting component 5 includes a main frame 501, which is located inside the scrubbing tower 1 near the gas outlet 6. A rectangular frame is fixed inside the main frame 501, and multiple baffles 504 are fixed at equal intervals inside the rectangular frame. Four sets of sealing plate units are provided between the main frame 501 and the rectangular frame. Each set of sealing plate units includes two sealing plates 502. The two sealing plates 502 are fixed to the upper and lower ends of the main frame 501 by locking bolts 503. A sealing gasket is provided between the main frame 501 and the sealing plates 502. The main frame 501, the rectangular frame, and the two sealing plates 502 form a sealed chamber, and a cleaning unit is provided inside the sealed chamber. The working principle of the above technical solution is as follows: In the demisting component 5, the airflow carrying tiny droplets is forced to change direction when passing through the baffle 504. The droplets impact the plate surface due to inertia and gather into larger droplets, which then flow into the collection structure below with gravity. The sealed chamber design between the main frame 501 and the rectangular frame, with the cleaning unit located inside the sealed chamber, ensures that the hydraulic cylinder 507 in the cleaning unit will not come into contact with water vapor, thus improving the service life of the hydraulic cylinder 507. The detachable sealing plate unit is fixed by locking bolts 503, which facilitates regular maintenance and replacement of core components. This modular design greatly reduces maintenance difficulty, shortens downtime, and improves the overall availability of the equipment.

[0023] Example 7: Figures 1-14As shown, an arc-shaped groove 505 is provided below the baffle plate 504. The arc-shaped groove 505 is fixedly connected to the rectangular frame. The end of the arc-shaped groove 505 abuts against the inner wall of the main frame 501. A water outlet channel 506 is provided at the connection between the main frame 501 and the arc-shaped groove 505. The working principle of the above technical solution is as follows: the droplets captured by the baffle plate 504 flow down the plate surface to the lower end and drip into the arc-shaped groove 505. The design of the arc-shaped groove 505 ensures that the liquid will not flow back into the gas channel. The end of the arc-shaped groove 505 is in close contact with the inner wall of the main frame 501, ensuring that the droplets are smoothly discharged to the inner wall of the washing tower 1 through the arc-shaped groove 505 and the water outlet channel 506, and slide down the inner wall of the washing tower 1 to the bottom of the washing tower 1, avoiding contact between the droplets and the rising gas, thus increasing the demisting efficiency. This structural design is simple and efficient, and can achieve efficient demisting without the need for power equipment. At the same time, the collected washing liquid can be returned to the circulation system, reducing consumption.

[0024] Example 8: Figures 1-14 As shown, the cleaning unit includes a hydraulic cylinder 507, which is located in a sealed chamber and fixed on a rectangular frame. The output end of the hydraulic cylinder 507 is connected to a telescopic rod 508. A sealing packing is provided at the sliding connection between the telescopic rod 508 and the rectangular frame. A cleaning plate 509 is fixed at the front end of the telescopic rod 508. The cleaning plate 509 is slidably connected to a baffle plate 504. A cleaning block 510 is fixed at the lower end of the cleaning plate 509. The cleaning block 510 is slidably connected to an arc groove 505. Small holes are provided on both the washing tower body 1 and the main frame 501. The pipeline assembly of the hydraulic cylinder 507 passes through the small holes. Sealing packing is provided between the washing tower body 1 and the pipeline assembly, and between the main frame 501 and the pipeline assembly. Pipeline components include tubing and cables; The working principle of the above technical solution is as follows: When too many pollutants accumulate on the surface of the baffle plate 504, affecting the demisting efficiency, the hydraulic cylinder 507 is activated, the telescopic rod 508 retracts, and the cleaning plate 509 slides along the surface of the baffle plate 504 to scrape off the attached substances. At the same time, the cleaning block 510 cleans the deposits in the arc-shaped groove 505 to ensure smooth drainage. The sealing packing prevents water vapor from entering the sealed chamber, ensuring that the hydraulic cylinder 507 works in a dry environment. After cleaning is completed, the telescopic rod 508 moves the cleaning plate 509 to the preset position, and the demisting work continues. This automatic cleaning mechanism can be automatically triggered according to the preset time or pressure drop signal, which greatly reduces the frequency of manual maintenance, extends the service life of the equipment, and maintains a long-term stable demisting efficiency.
