Description

Technical Field

[0001] The present invention belongs to the technical field of scrubber spraying, and particularly relates to a scrubber spraying device for waste gas. Background Art

[0002] A scrubber spraying device for waste gas is a device for purifying waste gas. It mainly removes harmful components in the waste gas, such as acidic gases, alkaline gases, volatile organic compounds, etc., through liquid absorption, reaction or physical adsorption. Its basic principle is that inside the scrubber, the waste gas contacts with the spraying liquid, so as to realize the exchange of pollutants in the gas and the liquid. The pollutants are absorbed, dissolved or neutralized, and finally the purified waste gas is discharged into the atmosphere.

[0003] When the traditional scrubber spraying device for waste gas is in use, after injecting the waste gas into the scrubber and then passing through the shunt screen, the nozzles at the top of the scrubber spray water to purify the rising waste gas. Since the waste gas rises from the bottom and passes through the shunt screen, and then the washing liquid is sprayed by the top nozzles, there may not be enough contact time for the air flow to fully mix with the liquid in the rising path in the tower, which will cause the pollutants in the waste gas not to be effectively captured. Especially for pollutants with low concentration or difficult to remove, the purification effect may not be good. Moreover, the shunt screen cannot evenly distribute the air flow completely, making the air flow in the tower uneven. The air flow in some areas may be more concentrated, resulting in poor washing effect in these areas. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a scrubber spraying device for waste gas.

[0005] The technical solution adopted to solve the above technical problem is: a scrubber spraying device for waste gas, including a tower body. An exhaust pipe is installed at the top end of the tower body, and a filter plate fixedly connected to the inner wall of the exhaust pipe is arranged between the tower body and the exhaust pipe. One side at the bottom of the tower body is communicated with a waste gas inlet pipe, and a plurality of observation windows are linearly and symmetrically arranged on the outer wall of the tower body. At the same time, a water tank fixedly installed on the outer wall of the tower is arranged on one side at the bottom of the waste gas inlet pipe. A flow guide plate is arranged inside the tower body, and the flow guide plate is fixedly connected to the inner wall of the tower body at the center of the tower body. The top and bottom of the flow guide plate are arranged in a mirror-image trapezoidal structure. A water wave filtering mechanism fixedly connected to the inner wall of the tower is arranged inside the tower body at the bottom of the flow guide plate, which is used to increase the contact area and contact time between the waste gas and the liquid. A circulating swing spraying mechanism is arranged inside the tower body at the top of the flow guide plate, which is used to improve the coverage range of the sprayed liquid.

[0006] Through the above technical solution, the combined action of the revolving swing of the spray head and the staggered cyclic movement of several rings can significantly improve the uniform distribution of the airflow in the scrubbing tower. The multi-angle spraying of the spray head and the water wave flow formed by several rings avoid the concentration of waste gas in certain areas, ensure the uniform distribution of the airflow, and avoid the imbalance in waste gas treatment.

[0007] Furthermore, the water wave filtering mechanism includes a support frame fixedly connected to the inner wall of the tower body, and the support frame is arranged in a U-shaped structure. A plurality of cams are provided at the bottom of the support frame, and the plurality of cams are arranged in a staggered manner on the vertical plane of the support frame. At the same time, the plurality of cams are divided into two groups and arranged in a mirror image with the midline of the support frame as the axis. One of the cams is located at the midline of the support frame, and the tops of the plurality of cams are arranged in different directions. A fixing rod is rotatably connected through the plurality of cams, and the fixing rod is located at the eccentric position of the cam. At the same time, the connections between the cams in each group divided into two groups and the fixing rod are all different. Both ends of the fixing rod are rotatably connected to the support frame.

[0008] Through the above technical solution, the movement similar to water wave ripples can make the contact between the waste gas and the liquid more sufficient. The airflow shows a fluctuating flow under the action of several rings, making the liquid contact the waste gas more evenly, thereby improving the waste gas purification efficiency, and the pollutants in the waste gas are more easily adsorbed or dissolved into the liquid.

[0009] Furthermore, a fan wheel is rotatably connected to the bottom of the support frame, and chain assemblies are arranged on both sides of the bottom of the support frame. At the same time, the two sprockets in the chain assemblies are rotatably connected through the support frame. The through ends of the two sprockets in the chain assemblies are respectively fixedly connected to the fan wheel and the fixing rod. A connecting rod is rotatably connected to the tops of the plurality of cams, and the other end of the connecting rod is slidably connected through the support frame. At the same time, a ring is fixedly connected to the through end of the connecting rod.

[0010] Through the above technical solution, since the staggered movement of several rings can avoid the accumulation of impurities in the waste gas, reduce the wear and blockage inside the tower, therefore, the maintenance frequency of the equipment is low, the service life of the equipment is extended, and the maintenance cost is reduced.

[0011] Furthermore, several of the rings are sleeved with each other, and there are gaps between several of the rings. A metal ball is fixedly connected to the top end of the connecting rod located at the midline of the support frame, and the metal ball is located in the middle of several of the rings. Several of the rings are located in the middle of the flow guide plate.

[0012] Through the above technical solution, it is possible to effectively reduce the airflow dead zone and retention phenomenon in the scrubbing tower. Through the disturbance of the water wave pattern, the airflow can pass through the tower more smoothly, avoiding the situation where the waste gas cannot be fully treated, and improving the waste gas treatment capacity and effect.

[0013] Furthermore, the cyclic swing spraying mechanism includes a fixing frame fixedly connected to the inner wall of the tower body, and a support base fixedly connected to the bottom of the fixing frame. The top end of the support base is rotatably connected to a disc, and a spherical structure is arranged at the center of the bottom of the disc. At the same time, the spherical end at the bottom of the disc is located inside the top end of the support base and is rotatably connected thereto. A plurality of spray heads are fixedly connected to the bottom surface of the disc in a circumferentially symmetric distribution. A tapered pipe is welded to the center of the top surface of the disc, and the tapered pipe, the disc, and the spray heads are of a hollow structure. At the same time, the interiors of the tapered pipe, the disc, and the spray heads are in communication with each other.

[0014] Through the above technical solution, the cyclic swing spray head can avoid the long-term accumulation of liquid at the spray head, reduce the risk of spray head blockage due to liquid accumulation, scaling, or impurities. The swinging and rotating movements of the spray head help to remove impurities on the surface of the spray head, ensure the stable operation of the system, and reduce the maintenance frequency and downtime.

[0015] Furthermore, a connecting pipe is rotatably connected through the end of the tapered pipe away from the disc, and the penetrating end of the tapered pipe is located at the eccentric position of the connecting pipe. The top end of the connecting pipe is rotatably connected to the fixing frame. A L-shaped connecting plate is fixedly connected to the center of the top end of the fixing frame. A first bevel gear is rotatably connected to one side of the top of the L-shaped connecting plate, and the first bevel gear is drivingly connected to a second bevel gear. The connecting shaft of the second bevel gear is rotatably connected through the L-shaped connecting plate and the fixing frame. At the same time, the penetrating end of the connecting shaft of the second bevel gear is fixedly connected to the connecting pipe.

[0016] Through the above technical solution, through the revolution and swinging spraying, the spray head can more effectively spray the liquid to all corners of the tower body, avoid liquid waste, have a wide liquid coverage area, ensure that every drop of liquid can effectively participate in the waste gas purification process, thereby reducing the liquid consumption and saving resources.

[0017] Furthermore, a driving motor is installed on one side of the top of the tower body. The output end of the driving motor is rotatably connected through the tower body and the L-shaped connecting plate, and the penetrating end of the driving motor is fixedly connected to the first bevel gear. Two sides of the top surface of the disc are slidably connected with sliding rods, and the contact end of the sliding rods with the disc is of a hemispherical structure. The end of the sliding rod away from the disc is fixedly connected to a spring rod, and the other end of the spring rod is fixedly connected to the fixing frame.

[0018] Through the above technical solution, due to the movement mode of the rotary swing spraying, the liquid can collide with the waste gas with higher efficiency, increasing the contact time and surface area of the gas-liquid interface, thereby improving the absorption efficiency of pollutants in the waste gas.

[0019] Furthermore, a spray pipe is installed on one side of the outer wall of the tower body. One end of the spray pipe is fixedly connected through the outer wall of the tower body, and the penetrating end of the spray pipe is rotatably connected through the second bevel gear, the L-shaped connecting plate and the fixing frame. At the same time, the penetrating end of the spray pipe is located inside the connecting pipe. A hose is used to connect and fix the penetrating end of the spray pipe located inside the connecting pipe and one end of the conical pipe located inside the connecting pipe to achieve penetration.

[0020] The beneficial effects of the present invention are as follows: (1) By adopting the water wave filtering mechanism of the present invention, when the waste gas enters the tower body through the waste gas inlet pipe and moves upward, the waste gas drives the fan wheel to rotate, so that the chain components on both sides are driven, and then drives the fixed rod to rotate, so that several cams draw an elliptical motion with the connection point with the fixed rod as the origin. The cam and the fixed rod generate relative rotation, so that while the connecting rod generates relative rotation with the cam, it moves up and down reciprocally, prompting a metal ball and several rings to move up and down reciprocally synchronously. Since the connection points of the fixed rod and several cams in a group are separate eccentric points, several rings and a metal ball move up and down reciprocally at different time periods, realizing a movement similar to water wave ripples. Under the action of the guide plate, the waste gas passes through the gaps between the moving metal ball and the rings, greatly increasing the contact surface area between the air flow and the liquid, enabling the liquid to spread more evenly in the air flow, thereby effectively improving the contact effect between the waste gas and the liquid and enhancing the removal efficiency of pollutants;

[0021] (2) By adopting the circulating swing spray mechanism of the present invention, the driving motor runs to drive the first bevel gear to rotate, thereby driving the second bevel gear, driving the connecting pipe at the bottom to rotate, prompting the conical pipe connected to the eccentric part at the bottom of the connecting pipe to rotate synchronously with the connecting pipe, and the hose inside the connecting pipe deforms. Furthermore, while the disc rotates following the conical pipe, it swings up and down with the connecting pipe as the origin. The conical pipe and the connecting pipe generate relative rotation. While the disc rotates and swings up and down cyclically, the spray head at the bottom of the disc rotates and swings synchronously. The tap water in the spray pipe enters the conical pipe through the hose, and then passes through the disc and the inside of the spray head, and is sprayed out from the bottom of the rotating and swinging spray head to spray and purify the waste gas after flow disturbance, which can make the waste gas be more comprehensively treated in the scrubbing tower, not only increasing the contact opportunity between the liquid and the waste gas, but also ensuring that various pollutants in the waste gas are evenly absorbed, improving the overall treatment capacity of the waste gas purification tower.

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] As Figures 1-10As shown, a spray device for a waste gas scrubbing tower in this embodiment includes a tower body 11. An exhaust gas outlet pipe 13 is installed at the top of the tower body 11. A filter plate 17 fixedly connected to the inner wall of the exhaust gas outlet pipe 13 is provided between the tower body 11 and the exhaust gas outlet pipe 13. An exhaust gas inlet pipe 12 is connected to one side of the bottom of the tower body 11. A number of observation windows 15 are linearly arranged at intervals on the outer wall of the tower body 11. At the same time, a water tank 14 fixedly installed on the outer wall of the tower body 11 is provided on one side of the bottom of the exhaust gas inlet pipe 12. An existing water pump is installed in the water tank 14, and the water pump is connected to the inside of the tower body 11. A flow guide plate 18 is arranged inside the tower body 11, and the flow guide plate 18 is fixedly connected to the inner wall of the tower body 11 at the center of the tower body 11. The combined action of the revolution and swing of the spray head 311 and the staggered cyclic movement of a number of rings 23 can significantly improve the uniform distribution of the gas flow in the scrubbing tower. The multi-angle spraying of the spray head 311 and the water wave flow formed by a number of rings 23 prevent the waste gas from concentrating in certain areas, ensuring uniform gas flow distribution and avoiding uneven waste gas treatment. The top and bottom of the flow guide plate 18 are arranged in a mirror trapezoidal structure.

[0036] As Figures 2-9 As shown, a water wave filtering mechanism 2 fixedly connected to the inner wall of the tower body 11 is arranged inside the tower body 11 at the bottom of the flow guide plate 18 for increasing the contact area and contact time between the waste gas and the liquid. The water wave filtering mechanism 2 includes a support frame 21 fixedly connected to the inner wall of the tower body 11. A fan wheel 26 is rotatably connected to the bottom of the support frame 21. Chain assemblies 27 are arranged on both sides of the bottom of the support frame 21. At the same time, the two sprockets in the chain assemblies 27 are rotatably connected through the support frame 21. A movement similar to water wave ripples can make the contact between the waste gas and the liquid more sufficient. The gas flow shows a fluctuating flow under the action of a number of rings 23, making the liquid contact the waste gas more evenly, thereby improving the waste gas purification efficiency. Pollutants in the waste gas are more easily adsorbed or dissolved in the liquid. The through ends of the two sprockets in the chain assemblies 27 are respectively fixedly connected to the fan wheel 26 and a fixed rod 25. The tops of a number of cams 24 are rotatably connected to a connecting rod 22, and the other end of the connecting rod 22 is slidably connected through the support frame 21. At the same time, the through end of the connecting rod 22 is fixedly connected to a ring 23. A number of rings 23 are sleeved with each other, and gaps are provided between a number of rings 23.

[0037] As Figures 3-9As shown, at the top of the connecting rod 22 located at the midline of the support frame 21, a metal ball 28 is fixedly connected, and the metal ball 28 is located in the middle of a plurality of rings 23. The plurality of rings 23 are located in the middle of the flow guide plate 18. The support frame 21 is arranged in a U-shaped structure. A plurality of cams 24 are arranged at the bottom of the support frame 21, and the plurality of cams 24 are arranged in a staggered manner on the vertical plane of the support frame 21. Since the staggered movement of the plurality of rings 23 can avoid the accumulation of impurities in the exhaust gas, reduce the wear and blockage inside the tower, therefore, the maintenance frequency of the equipment is lower, the service life of the equipment is extended, and the maintenance cost is reduced. At the same time, the plurality of cams 24 are divided into two groups and are arranged in a mirror image with the midline of the support frame 21 as the axis. One of the cams 24 is located at the midline of the support frame 21, and the tops of the plurality of cams 24 are arranged in different directions. A fixing rod 25 is rotatably connected through the plurality of cams 24, and the fixing rod 25 is located at the eccentric position of the cam 24, which can effectively reduce the air flow dead zone and retention phenomenon in the scrubbing tower. Through the disturbance of the water ripples, the air flow can pass through the tower more smoothly, avoiding the situation where the exhaust gas cannot be fully treated, improving the treatment capacity and effect of the exhaust gas. At the same time, the connections between the cams 24 in each group divided into two groups and the fixing rod 25 are different, and both ends of the fixing rod 25 are rotatably connected to the support frame 21.

[0038] As Figures 1-11As shown, a circulating swing spraying mechanism 3 is arranged inside the tower body 11 at the top of the deflector 18, which is used to improve the coverage range of the sprayed liquid. The circulating swing spraying mechanism 3 includes a fixing frame 31 fixedly connected to the inner wall of the tower body 11, and a support base 32 is fixedly connected to the bottom of the fixing frame 31. A disc 310 is rotatably connected to the top end of the support base 32, and a spherical structure is arranged at the center of the bottom of the disc 310. At the same time, the spherical end at the bottom of the disc 310 is located inside the top end of the support base 32 and is rotatably connected thereto. Due to the movement mode of rotating and swinging spraying, the liquid can collide with the waste gas with higher efficiency, increasing the contact time and surface area of the gas-liquid interface, thereby improving the absorption efficiency of pollutants in the waste gas. A plurality of nozzles 311 are fixedly connected to the bottom end surface of the disc 310 and are arranged in a circumferentially symmetric distribution. The circulating swing nozzles 311 can avoid the liquid accumulating at the nozzles 311 for a long time, reducing the risk of nozzle 311 blockage due to liquid accumulation, scaling or impurities. The swinging and rotating actions of the nozzles 311 help to remove the impurities on the surface of the nozzles 311, ensure the stable operation of the system, reduce the maintenance frequency and downtime. A conical pipe 39 is welded to the center of the top end surface of the disc 310. One end of the conical pipe 39 away from the disc 310 is rotatably connected through a connecting pipe 36, and the penetrating end of the conical pipe 39 is located at an eccentric position of the connecting pipe 36. The top end of the connecting pipe 36 is rotatably connected to the fixing frame 31. An L-shaped connecting plate 33 is fixedly connected to the center of the top end of the fixing frame 31. A driving motor 312 is installed on one side of the top of the tower body 11. The output end of the driving motor 312 is rotatably connected through the tower body 11 and the L-shaped connecting plate 33, and the penetrating end of the driving motor 312 is fixedly connected to the first bevel gear 34.

[0039] As Figures 3-11As shown, slide rods 38 are slidably connected to both sides of the top surface of the disk 310, and the contact ends of the slide rods 38 with the disk 310 are arranged in a hemispherical structure. One end of the slide rod 38 away from the disk 310 is fixedly connected to a spring rod 37, and the other end of the spring rod 37 is fixedly connected to the fixed frame 31. One side of the top of the L-shaped connecting plate 33 is rotatably connected to a first bevel gear 34, and the first bevel gear 34 is drivingly connected to a second bevel gear 35. A spray pipe 16 is installed on one side of the outer wall of the tower body 11. One end of the spray pipe 16 is fixedly connected through the outer wall of the tower body 11, and the penetrated end of the spray pipe 16 is rotatably connected through the second bevel gear 35, the L-shaped connecting plate 33, and the fixed frame 31. At the same time, the penetrated end of the spray pipe 16 is located inside the connecting pipe 36. Through rotation and swinging spraying, the nozzle 311 can more effectively spray the liquid to all corners of the tower body 11, avoiding liquid waste, with a wide liquid coverage area, ensuring that every drop of liquid can effectively participate in the waste gas purification process, thereby reducing the consumption of the liquid and saving resources. The penetrated end of the spray pipe 16 located inside the connecting pipe 36 is connected and fixed to one end of a conical pipe 39 located inside the connecting pipe 36 through a hose to achieve penetration. Existing hoses are respectively connected and fixed to the spray pipe 16 and the conical pipe 39. When the connecting pipe 36 rotates, the hose rotates synchronously with the conical pipe 39 inside the connecting pipe 36 and undergoes bending deformation. The connecting shaft of the second bevel gear 35 is rotatably connected through the L-shaped connecting plate 33 and the fixed frame 31. At the same time, the penetrated end of the connecting shaft of the second bevel gear 35 is connected and fixed to the connecting pipe 36, and the conical pipe 39, the disk 310, and the nozzle 311 are arranged with hollow structures inside, and at the same time, the interiors of the conical pipe 39, the disk 310, and the nozzle 311 are in communication with each other.

[0040] The working principle of this embodiment is as follows. Before the present invention is used, after moving the overall equipment to the installation location, the spray pipe 16 is connected to the tap water pipeline, and the waste gas inlet pipe 12 is connected to the waste gas pipeline. Then, the waste gas enters the tower body 11 from the waste gas inlet pipe 12 and moves upward, while the clean tap water enters the top of the tower body 11 from the spray pipe 16 and is sprayed to spray and purify the upward-moving waste gas. The purified waste gas passes through the filter plate 17 and is discharged from the tower top outlet pipe 13. The liquid that falls to the bottom of the tower body 11 after spraying is recycled at the bottom of the tower body 11 under the action of the water tank 14 and the water pump inside it, or it can be discharged from the inside of the tower body 11.

[0041] When the waste gas enters the interior of the tower body 11 through the waste gas inlet pipe 12 and moves upward, the waste gas drives the fan wheel 26 to rotate, causing the chain assemblies 27 on both sides to drive, and then driving the fixed rod 25 to rotate, so that several cams 24 take the connection point with the fixed rod 25 as the origin and perform elliptical motion. The cams 24 and the fixed rod 25 generate relative rotation, so that while the connecting rod 22 generates relative rotation with the cams 24, it performs reciprocating up and down motion, prompting a metal ball 28 and several rings 23 to synchronously perform reciprocating up and down motion. Since the connection points of the fixed rod 25 with several cams 24 in a group are separate eccentric points, several rings 23 and a metal ball 28 perform reciprocating up and down motion at different time periods, realizing a motion similar to water ripple ripples. Under the action of the deflector 18, the waste gas passes through the gap between the moving metal ball 28 and the rings 23 to cause turbulence while reducing the air flow dead zone and retention phenomenon in the tower body 11.

[0042] Then the driving motor 312 operates to drive the first bevel gear 34 to rotate, thereby driving the second bevel gear 35, driving the connecting pipe 36 at the bottom to rotate, prompting the conical pipe 39 connected to the eccentric part at the bottom of the connecting pipe 36 to rotate synchronously with the connecting pipe 36, and the hose in the connecting pipe 36 deforms, so that while the disc 310 rotates following the conical pipe 39, it swings up and down with the connecting pipe 36 as the origin. The conical pipe 39 and the connecting pipe 36 generate relative rotation. While the disc 310 rotates and swings up and down in a cycle, the spray head 311 at the bottom of the disc 310 synchronously rotates and swings, and the sliding rod 38 generates relative sliding with the disc 310, and the two spring rods 37 contract to different degrees, thereby supporting the disc 310. Then the tap water in the spray pipe 16 enters the interior of the conical pipe 39 through the hose, and then passes through the interior of the disc 310 and the spray head 311, and is sprayed out from the bottom of the rotating and swinging spray head 311 to spray and purify the waste gas after turbulence. The way of spraying liquid is more flexible and comprehensive, which can increase the contact time and contact area between the waste gas and the liquid, and the enhanced gas-liquid contact helps to improve the removal efficiency of the scrubbing tower, especially for treating high-concentration or difficult-to-treat waste gas.
