Description

Technical Field

[0001] This invention belongs to the field of waste gas recovery technology, specifically a waste gas recovery device for waste treatment. Background Technology

[0002] In the process of municipal solid waste treatment, the collection, transportation, stockpiling, and fermentation of waste generate a large amount of waste gas containing pollutants such as particulate matter, volatile organic compounds (VOCs), hydrogen sulfide, and ammonia. Direct emission of these gases would seriously harm the surrounding atmospheric environment and the health of residents. Therefore, efficient purification of waste treatment waste gas has become a key link in achieving green and sustainable development in the waste treatment industry.

[0003] Currently, the mainstream waste gas treatment process typically employs a two-stage treatment mode of filtration and spraying. First, solid particulate matter in the waste gas is removed through equipment such as pre-filters and bag filters to achieve preliminary purification. Then, the waste gas is introduced into the spray chamber and mixed with absorbent liquid (such as water, alkaline solution, oxidant, etc.) sprayed from top to bottom. Utilizing the gas-liquid mass transfer process, soluble harmful components in the waste gas are captured, neutralized, or oxidized and decomposed by the absorbent liquid, ultimately achieving emission standards.

[0004] Traditional spraying devices mostly use fixed nozzles. Under the action of gravity, the spray liquid forms a continuous liquid film or large droplets, which has a limited contact surface area with the exhaust gas. It is also easy to form short-circuit flow in the chamber, causing some exhaust gas to be discharged directly without sufficient contact with the spray liquid, creating a purification blind zone. On the other hand, the liquid accumulated at the bottom of the chamber is often in a stagnant or slow-flowing state. It cannot be reused and is easy to become a dead zone for pollutant deposition and bacterial growth, and even produce foul odors and sludge, increasing the difficulty of equipment maintenance and the risk of secondary pollution.

[0005] Therefore, the present invention provides a waste gas recovery device for waste treatment. Summary of the Invention

The storage cylinder is fixedly installed on the inner wall of the mounting plate, and one end of the connecting pipe is fixed to the outer wall of the storage cylinder, while the other end extends into the interior of the absorption layer.

[0008] Preferably, the control mechanism includes a control motor, a drive shaft, and a shield; The drive shaft is rotatably connected to the closed cover, and one end extends into the inner cavity of the spray chamber. The control motor is fixedly installed on the outer wall of the closed cover, and the output shaft of the control motor is fixedly connected to the axial end of the drive shaft. The drive shaft passes through the mounting plate and is fixedly connected to the mounting plate. The shield is fixedly installed on the axial end of the drive shaft.

[0009] Preferably, a control plug is slidably installed in the inner cavity of the storage cylinder, a support plate is fixedly installed on the bottom surface of the control plug, the side wall of the support plate is slidably attached to the inner wall of the mounting plate, the bottom surface of the support plate is connected to the inner wall of the mounting plate through an elastic element, and a transmission rod is fixedly installed on the outer wall of the support plate. When the mounting plate rotates, the transmission rod is pressed against the heat exchange plate.

[0010] Preferably, a control rod is rotatably mounted on the outer wall of the mounting plate via a torsion spring, and a striking cylinder for striking the arc-shaped plate is rotatably mounted on one end of the control rod; A control gear is rotatably mounted on the outer wall of the mounting plate, and the control gear is used to move the control lever.

[0011] Preferably, a guide cylinder is fixedly installed on the outer wall of the mounting plate, a control shaft is rotatably installed inside the guide cylinder, a transmission cover is fixedly installed on the outer wall of the control shaft, a transmission ratchet is fixedly installed on the outer wall of the control gear plate, and a transmission ratchet bar that cooperates with the transmission ratchet is elastically installed on the inner wall of the transmission cover. A transmission plug is slidably installed in the inner cavity of the guide cylinder. A transmission ring is fixedly installed at the axial end of the transmission plug through a connecting rod. The control shaft passes through the transmission ring, and the outer wall of the control shaft slides against the inner wall of the transmission ring. The radial outer wall of the control shaft is provided with a helical groove, and the inner wall of the transmission ring is fixedly installed with balls that slide in cooperation with the helical groove. A guide rod is fixedly installed on the inner wall of the guide cylinder. The guide rod passes through the transmission ring and is slidably connected to the transmission ring. Multiple guide rods are provided, and the multiple guide rods are evenly arranged in a ring along the axis of the transmission ring.

[0012] Preferably, a guide tube is fixedly installed on the outer wall of the mounting plate, and a sliding plug is slidably installed in the inner cavity of the guide tube. The guide tube has a unidirectional air inlet end and an exhaust end. The air inlet end of the guide tube is connected to the inner cavity of the spray chamber, and the exhaust end of the guide tube is connected to the inner cavity of the guide tube. The inner wall of the spray chamber is fixedly installed with a guide rail, the inner wall of the guide rail is slidably installed with an installation beam, the outer wall of the installation beam is fixedly installed with a transmission collar, and the outer wall of the transmission collar is fixedly connected to the outer wall of the sliding plug.

[0013] The beneficial effects of this invention are as follows: 1. This invention effectively solves the technical problems of insufficient gas-liquid mixing, purification blind spots, and easy sedimentation at the bottom in traditional spray devices by setting up an arc-shaped plate, an absorption layer, and a shield. When the arc-shaped plate rotates, it lifts up the bottom absorption liquid, forming a double gas-liquid contact with the top spray, which greatly increases the gas-liquid contact area and contact time, thereby improving the pollutant absorption efficiency. The absorption layer rotates with the arc-shaped plate, which can not only adsorb the absorption liquid to achieve secondary spraying, but also shake off the attached pollutants to avoid blockage. The shield can divert the waste gas to prevent excessive local concentration. At the same time, it disturbs the airflow with the rotation of the drive shaft, breaks the airflow short circuit, promotes the full mixing of waste gas and absorption liquid, and protects the sealing structure to reduce waste gas leakage. It significantly improves the purification stability of the device and solves the inherent defects of single spray. 2. This invention achieves multi-functional synergy and energy-saving optimization by setting up a transmission ratchet, a transmission ratchet wheel, and a guide tube. The unidirectional transmission of the transmission ratchet and the transmission ratchet wheel can convert the reciprocating rotation of the control shaft into the unidirectional rotation of the control gear plate, realizing the reciprocating impact of the arc plate without the need for an additional power source. The guide tube realizes the intermittent air injection of the guide tube through a one-way valve, and with the spring driving the transmission plug to slide back and forth, it drives the control shaft to rotate. This provides stable power for the impact and can further disturb the gas-liquid mixture in the spray chamber by utilizing airflow. At the same time, this structure does not require additional drive equipment, which greatly reduces energy consumption. It can also enhance the breaking effect of the absorbent liquid through impact and vibration, improving the long-term operational reliability of the device and the comprehensiveness of waste gas treatment.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1 to 8 As shown, the waste gas recovery device for waste treatment according to the present invention includes a treatment section, a spraying section, a control mechanism, a turbulence mechanism, and a jetting mechanism.

[0019] The treatment unit includes a filter 2, a spray chamber 1, and a sealing cover 3. The sealing cover 3 is detachably installed at one end of the spray chamber 1. The sealing cover 3 is connected to the spray chamber 1 through a flange to form a sealed chamber. An exhaust pipe is provided above the sealing cover 3, and a drain pipe is provided at the bottom of the sealing cover 3.

[0020] The output end of filter 2 is connected to the inner cavity of spray chamber 1. The waste gas generated by waste treatment is passed into filter 2 to filter the solid particles in the waste gas, and then passed into the inner cavity of spray chamber 1. After the waste gas is treated in spray chamber 1, the gas is discharged through the exhaust pipe and the liquid is discharged through the drain pipe.

[0021] The spray unit includes a spray head 8 and a heat exchange plate 5. The spray head 8 is fixedly installed on the top of the spray chamber 1, and the heat exchange plate 5 is fixedly installed on the bottom of the spray chamber 1. The spray head 8 is connected to an external water source. When the exhaust gas is introduced into the spray chamber 1, the absorbent liquid is sprayed to treat the exhaust gas. At this time, the heat in the exhaust gas is absorbed by the heat exchange plate 5 and discharged to the outside of the spray chamber 1.

[0022] The turbulence mechanism includes a mounting plate 10, an arc-shaped plate 11, and an absorption layer 7. The absorption layer 7 is fixedly installed on the outer wall of the arc-shaped plate 11. The arc-shaped plate 11 is made of elastic material, and one end is fixedly connected to the radial outer wall of the mounting plate 10. The mounting plate 10 is rotatably installed inside the spray chamber 1. Rotating the mounting plate 10 drives the arc-shaped plate 11 to rotate synchronously. Multiple arc-shaped plates 11 are evenly arranged in a ring along the axis of the mounting plate 10.

[0023] The control mechanism is used to control the rotation of the mounting plate 10. After the absorbent sprayed by the spray head 8 accumulates at the bottom of the spray chamber 1, the control mechanism drives the mounting plate 10 to rotate inside the spray chamber 1. The mounting plate 10 drives multiple arc-shaped plates 11 fixedly connected to its radial outer wall to rotate synchronously. During the rotation, the arc-shaped plates 11 continuously stir up the absorbent collected at the bottom, so that the absorbent is thrown into the inner cavity of the spray chamber 1 in the form of droplets or liquid mist, and comes into contact with the exhaust gas introduced from the filter 2 again. At the same time, the absorption layer 7 fixed to the outer wall of the arc-shaped plate 11 will also rotate with it, further increasing the gas-liquid contact area and strengthening the mixing and mass transfer process of exhaust gas and absorbent.

[0024] The installation plate 10 drives the arc-shaped plate 11 to rotate, stirring up the absorbent liquid and creating a dynamic liquid mist field within the spray chamber 1. This forms a dual gas-liquid contact with the static spray from the spray head 8, significantly increasing the effective contact area and contact time between the exhaust gas and the absorbent liquid. This improves the absorption efficiency of pollutants in the exhaust gas and solves the problem of insufficient mixing effect from a single spray. The rotation of the arc-shaped plate 11 breaks the static state of the absorbent liquid at the bottom of the spray chamber 1, preventing pollutant deposition. At the same time, the slight vibration generated by the rotation of the elastic arc-shaped plate 11 can shake off particles attached to the absorption layer 7, reducing scaling and clogging, and improving the operational stability and service life of the device. The blowing mechanism includes a storage cylinder 19 and a connecting pipe 17. The storage cylinder 19 is fixedly installed on the inner wall of the mounting plate 10. One end of the connecting pipe 17 is fixed to the outer wall of the storage cylinder 19, and the other end extends into the interior of the absorption layer 7. The absorption and discharge of the connecting pipe 17 can be controlled by adjusting the air pressure inside the storage cylinder 19.

[0025] When the mounting plate 10 rotates to the point where the absorption layer 7 is below the surface of the absorbent liquid, the control connecting pipe 17 draws out the absorbent liquid. At the same time, the absorption layer 7 absorbs the absorbent liquid accumulated at the bottom of the spray chamber 1. When the mounting plate 10 rotates to the point where the absorption layer 7 is above the surface of the liquid, the control connecting pipe 17 vents the air. At this time, the absorbent liquid absorbed into the inner cavity is discharged, and the absorbent liquid is sprayed out through the absorption layer 7.

[0026] On the one hand, the absorption layer 7 is kept moist and in a highly efficient absorption state through the circulation of adsorption below the liquid surface and spraying on the liquid surface, avoiding the decrease in efficiency due to dryness or the adhesion of pollutants. At the same time, the sprayed absorbent liquid can form a secondary contact with the exhaust gas, further enhancing gas-liquid mass transfer. On the other hand, the air pressure regulation of the storage cylinder 19 and the connecting pipe 17 can precisely control the timing and flow of suction and discharge, making the utilization of the absorbent liquid more targeted. This not only improves the purification efficiency but also reduces the ineffective consumption of the absorbent liquid. At the same time, the absorbent layer 7 can be self-cleaned by the airflow, reducing the risk of scaling and clogging.

[0027] The control mechanism includes a control motor 4, a drive shaft 6, and a shield 9. The drive shaft 6 is rotatably connected to the closed cover 3, and one end extends into the inner cavity of the spray chamber 1. A sealed bearing is provided at the contact position between the drive shaft 6 and the closed cover 3.

[0028] The control motor 4 is fixedly installed on the outer wall of the closed cover 3, and the output shaft of the control motor 4 is fixedly connected to the axial end of the transmission shaft 6. The control motor 4 drives the transmission shaft 6 to rotate synchronously.

[0029] The drive shaft 6 passes through the mounting plate 10 and is fixedly connected to the mounting plate 10. When the drive shaft 6 rotates, it drives the mounting plate 10 to rotate, thereby controlling the rotation of the arc plate 11.

[0030] The shield 9 is fixedly installed on the axial end of the drive shaft 6. The shield 9 has an arc-shaped structure with its arc surface facing the air inlet of the spray chamber 1. When the filter 2 inputs gas into the spray chamber 1, it impacts the surface of the shield 9 and then disperses, avoiding the formation of blind spots due to excessively high local exhaust gas concentration. In addition, the shield 9 is fixedly installed on the axial end of the drive shaft 6 and rotates synchronously with the drive shaft 6, which can further disturb the airflow in the spray chamber 1, promote full contact between the exhaust gas and the absorbent liquid sprayed by the spray head 8, the liquid mist stirred up by the arc plate 11, and the absorbent liquid seeping out of the absorbent layer 7, enhance the gas-liquid mass transfer efficiency, and at the same time reduce the direct impact of exhaust gas on the sealed bearing, reduce the wear at the seal and the risk of exhaust gas leakage. In conjunction with the drive shaft 6 driven by the control motor 4 to drive the rotation of the mounting plate 10 and the arc plate 11, the coordinated optimization of airflow disturbance and liquid flow circulation is achieved, improving the overall exhaust gas purification effect.

[0031] In a preferred embodiment of the present invention, a control plug 20 is slidably installed in the inner cavity of the storage cylinder 19. By sliding and adjusting the control plug 20, the pressure inside the storage cylinder 19 can be adjusted, thereby enabling the suction and discharge of the connecting pipe 17.

[0032] A support plate 15 is fixedly installed on the bottom surface of the control plug 20, and the sliding support plate 15 drives the control plug 20 to slide synchronously.

[0033] The side wall of the support plate 15 slides against the inner wall of the mounting plate 10. The bottom surface of the support plate 15 is connected to the inner wall of the mounting plate 10 through an elastic element. A transmission rod 14 is fixedly installed on the outer wall of the support plate 15. When the mounting plate 10 rotates, the transmission rod 14 is pressed by the heat exchange plate 5. Pressing the transmission rod 14 drives the support plate 15 and the control plug 20 to slide.

[0034] Initially, the elastic element on the bottom surface of the support plate 15 is in a naturally extended state, the transmission rod 14 is not in contact with the heat exchange plate 5, and the control plug 20 inside the storage cylinder 19 remains in its initial position. When the control motor 4 drives the mounting plate 10 to rotate via the transmission shaft 6, the mounting plate 10 synchronously drives the transmission rod 14, the support plate 15, and the control plug 20 to rotate. As the rotation angle increases, the transmission rod 14 contacts and is pressed against the heat exchange plate 5 at the bottom of the spray chamber 1, thereby driving the support plate 15 to overcome the elastic force of the elastic element and slide along the inner wall of the mounting plate 10. The support plate 15 drives the control plug 20 to slide synchronously inside the storage cylinder 19, completing the pre-adjustment of the air pressure inside the storage cylinder 19. When the mounting plate 10 continues to rotate to... When the absorption layer 7 on the outer wall of the arc plate 11 is below the liquid level of the bottom absorbent in the spray chamber 1, the transmission rod 14 separates from the heat exchange plate 5, and the control plug 20 slides back to its original position under the elastic force of the elastic element, so that a negative pressure is formed in the inner cavity of the storage cylinder 19, and then the absorbent is drawn out through the connecting pipe 17. At the same time, the absorption layer 7 absorbs the bottom absorbent. As the mounting plate 10 continues to rotate, the transmission rod 14 contacts the heat exchange plate 5 again and is pressed down, which drives the support plate 15 and the control plug 20 to slide again, changing the air pressure in the inner cavity of the storage cylinder 19. The absorbent drawn out in the storage cylinder 19 is pushed to the absorption layer 7 through the connecting pipe 17 and sprayed into the inner cavity of the spray chamber 1 through the absorption layer 7, realizing the extraction and discharge cycle of the absorbent.

[0035] A control lever 18 is rotatably mounted on the outer wall of the mounting plate 10 via a torsion spring. After the control lever 18 is rotated and adjusted, it is released. The spring force of the torsion spring drives the control lever 18 to reset. A striking cylinder 16 for striking the arc plate 11 is rotatably mounted on one end of the control lever 18. During the reset process of the control lever 18, the striking cylinder 16 strikes the outer wall of the arc plate 11, thereby causing the arc plate 11 to vibrate.

[0036] A control gear 21 is rotatably mounted on the outer wall of the mounting plate 10. The control gear 21 is used to actuate the control lever 18. Rotating the control gear 21 pushes the control lever 18 to deflect. After the control gear 21 and the control lever 18 separate, the control lever 18 returns to its original position and is then struck by the striking cylinder 16 to achieve the striking of the arc plate 11.

[0037] On the one hand, it can shake off the pollutants and particulate matter attached to the absorption layer 7 on the outer wall of the arc plate 11, avoid clogging of the absorption layer 7, maintain its absorption performance, and reduce the scale buildup on the surface of the arc plate 11, thus reducing the frequency of equipment maintenance. On the other hand, the shaking of the arc plate 11 can further break up the absorbent liquid it stirs up, forming a finer liquid mist, increasing the gas-liquid contact area, and enhancing the mixing and mass transfer efficiency with the exhaust gas introduced from the filter 2. At the same time, the energy generated by the shaking can be transferred to the absorbent liquid at the bottom of the spray chamber 1, reducing pollutant deposition, and cooperating with the suction and discharge circulation of the storage cylinder 19 and the connecting pipe 17.

[0038] In a preferred embodiment of the present invention, a guide cylinder 22 is fixedly installed on the outer wall of the mounting plate 10, and a control shaft 32 is rotatably arranged inside the guide cylinder 22, with the axis of the control shaft 32 coinciding with the axis of the guide cylinder 22.

[0039] A transmission cover 27 is fixedly installed on the outer wall of the control shaft 32, and a transmission ratchet 28 is fixedly installed on the outer wall of the control gear plate 21. A transmission ratchet 29 that cooperates with the transmission ratchet 28 is elastically installed on the inner wall of the transmission cover 27. Through the cooperation of the transmission ratchet 29 and the transmission ratchet 28, the unidirectional transmission between the control shaft 32 and the control gear plate 21 is realized. By reciprocating the rotation of the control shaft 32, the control gear plate 21 is driven to rotate in the same direction, thereby actuating the control lever 18 to strike the arc plate 11.

[0040] A transmission plug 25 is slidably installed in the inner cavity of the guide cylinder 22, wherein the outer wall of the transmission plug 25 is slidably attached to the inner wall of the guide cylinder 22.

[0041] A transmission ring 31 is fixedly installed on the axial end of the transmission plug 25 via a connecting rod. The axis of the transmission plug 25 coincides with the axis of the transmission ring 31. The sliding adjustment of the transmission plug 25 drives the transmission ring 31 to slide synchronously. The control shaft 32 passes through the transmission ring 31, and the outer wall of the control shaft 32 slides against the inner wall of the transmission ring 31. The axis of the transmission ring 31 coincides with the axis of the control shaft 32.

[0042] The radial outer wall of the control shaft 32 is provided with a spiral groove 30, and the inner wall of the transmission ring 31 is fixedly installed with a ball that slides with the spiral groove 30. The outer wall of the guide cylinder 22 is provided with a through hole, and a spring connected to the inner wall of the guide cylinder 22 is provided on the outer wall of the transmission plug 25. Gas is input into the inner cavity of the guide cylinder 22. At this time, some gas is discharged through the through hole outside the guide cylinder 22, and the gas pressure in the inner cavity of the guide cylinder 22 increases. The transmission plug 25 slides and finally stops injecting gas into the guide cylinder 22. The spring force affects the reset of the transmission plug 25, thereby realizing the reciprocating sliding adjustment of the transmission plug 25.

[0043] The reciprocating sliding transmission plug 25 drives the transmission ring 31 to slide back and forth. Through the cooperation of the ball and the spiral groove 30, it drives the control shaft 32 to rotate back and forth, which in turn drives the control gear plate 21 to rotate, thereby realizing the reciprocating impact on the arc plate 11.

[0044] To prevent the transmission ring 31 and transmission plug 25 from deflecting, a guide rod 26 is fixedly installed on the inner wall of the guide cylinder 22. The guide rod 26 passes through the transmission ring 31 and is slidably connected to the transmission ring 31. By setting the guide rod 26, the sliding trajectory of the transmission ring 31 is limited, thereby preventing the transmission ring 31 and transmission plug 25 from deflecting. Multiple guide rods 26 are provided, and the multiple guide rods 26 are evenly arranged in a ring along the axis of the transmission ring 31, further improving the sliding stability of the transmission ring 31.

[0045] A guide tube 24 is fixedly installed on the outer wall of the mounting plate 10. A sliding plug 23 is slidably installed in the inner cavity of the guide tube 24. The guide tube 24 has a unidirectional air inlet end and an exhaust end, and a one-way valve is provided in both the air inlet end and the exhaust end.

[0046] The air inlet of the guide tube 24 is connected to the inner cavity of the spray chamber 1, and the exhaust end of the guide tube 24 is connected to the inner cavity of the guide tube 22. The reciprocating sliding adjustment of the sliding plug 23 realizes the intermittent air injection into the inner cavity of the guide tube 22.

[0047] The inner wall of the spray chamber 1 is fixedly installed with a guide rail 12, and the inner wall of the guide rail 12 is slidably installed with a mounting beam 13. The guide rail 12 is designed to limit the stability of the sliding of the mounting beam 13.

[0048] A transmission collar 33 is fixedly installed on the outer wall of the mounting beam 13. The outer wall of the transmission collar 33 is fixedly connected to the outer wall of the sliding plug 23. The transmission shaft 6 passes through the transmission collar 33 and is connected to the transmission collar 33 through a reciprocating thread. When the transmission shaft 6 rotates, the transmission collar 33 slides back and forth, thereby controlling the sliding plug 23 to slide back and forth.

[0049] The control motor 4 drives the transmission shaft 6 to rotate, which in turn drives the transmission ring 33 to slide back and forth through the reciprocating thread. This, in turn, drives the sliding plug 23 to slide back and forth within the guide tube 24. The guide tube 24 intermittently injects air into the guide tube 22 through a one-way valve. When air is injected, the air pressure pushes the transmission plug 25 to slide. After the air injection stops, the transmission plug 25 returns to its original position under the action of the spring, achieving reciprocating sliding. The transmission plug 25 drives the transmission ring 31 to slide back and forth synchronously. The guide rod 26 ensures its sliding stability. The transmission ring 31 drives the control shaft 32 to rotate back and forth through the cooperation of the ball and the spiral groove 30. The one-way cooperation of the transmission ratchet 29 and the transmission ratchet 28 causes the control shaft 32 to rotate back and forth, driving the control gear 21 to rotate in one direction. The control gear 21 deflects the control rod 18. After separation, the control rod 18 returns to its original position under the action of the torsion spring, driving the striking cylinder 16 to strike the arc plate 11, causing it to vibrate and achieving reciprocating striking.

[0050] The reciprocating tapping of the tapping cylinder 16 against the arc-shaped plate 11 causes the elastic material of the arc-shaped plate 11 to vibrate regularly. This not only shakes off pollutants and particulate matter attached to the absorption layer 7, preventing blockage and maintaining absorption performance, but also breaks up the absorption liquid stirred up by the arc-shaped plate 11, increasing the gas-liquid contact area and enhancing the waste gas purification efficiency. At the same time, the tapping power comes from the transmission shaft 6 driven by the control motor 4, which does not require an additional power source, saving energy and disturbing the gas flow inside the spray chamber 1, breaking the airflow balance, promoting the full mixing of waste gas and absorption liquid, and further improving the overall treatment effect.
