Description

Technical Field

[0001] This invention relates to the field of purification tower technology, specifically a spray-type fiberglass purification tower. Background Technology

[0002] Industrial production processes generate a large amount of corrosive waste gas and harmful pollutants, such as hydrogen chloride, hydrogen fluoride, ammonia, and sulfuric acid mist. If these waste gases are directly emitted, they will seriously pollute the atmospheric environment and endanger human health. Therefore, it is necessary to use efficient and environmentally friendly treatment equipment for purification.

[0003] Currently, liquid absorption is the mainstream method for treating corrosive waste gas. Its core lies in the selection of purification equipment. Traditional purification equipment often has problems such as complex processes, cumbersome operation, and inconvenient maintenance. In addition, some equipment has poor corrosion resistance and a narrow range of applications, and cannot treat multiple pollutants at the same time. It is difficult to meet the treatment needs of enterprises for continuous and intermittent emissions, and may also affect the normal production of the workshop.

[0004] Meanwhile, traditional equipment suffers from high pressure drop, poor demisting performance, and difficulty in achieving national and local emission standards in terms of purification efficiency. Furthermore, the choice of tower material is limited, making it unsuitable for different working conditions. To address these pain points and meet the actual needs of industrial waste gas treatment, spray-type fiberglass purification towers have emerged, making them the preferred equipment for industrial waste gas purification.

[0005] Existing spray-type fiberglass purification towers cannot guarantee purification effect and efficiency during use. This is because, in order to improve purification efficiency, existing technologies inject purification liquid into the bottom of the tower body and prioritize injecting waste gas into the purification liquid. The waste gas is then initially purified by the purification liquid at the bottom of the tower body, and then further purified by spraying.

[0006] However, when the above purification method is used, the exhaust gas cannot fully contact the purification liquid at the bottom of the tower, thus failing to improve the purification efficiency. In addition, because the position of the spray nozzle is fixed during spraying, the exhaust gas will overflow from the blind area of ​​the spray, thus preventing the exhaust gas from being effectively purified.

[0007] Therefore, a spray-type fiberglass purification tower is needed to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a spray-type fiberglass purification tower to solve the problem mentioned in the background art that the existing spray-type fiberglass purification towers have poor efficiency and effectiveness in purifying waste gas.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A spray-type fiberglass purification tower includes a tower body and a drain outlet at its lower part. An exhaust port is located at the top of the tower body, and a spray plate for purifying waste gas is connected to the upper middle part of the tower body via a bearing. A water-absorbing layer is installed inside the exhaust port at the top of the tower body, and a gas-collecting plate is positioned between the water-absorbing layer and the spray plate. The gas-collecting plate is installed on the inner side of the tower body via support arms evenly distributed on its outer side, and an inlet pipe communicating with it is installed on the gas-collecting plate. The open end of the inlet pipe seamlessly extends to the outside of the tower body. The gas-collecting plate is connected to the spray plate via a liquid delivery hose evenly distributed on its outer side, and spray holes for spraying are provided on the lower surface of the spray plate. A mounting cover is provided on the bottom surface via a mounting base, and a support pipe is coaxially fixedly connected to the upper surface of the mounting cover. An exhaust seat is provided at equal angles on the upper surface of the mounting cover, which is connected to the outside of the support pipe. A connecting pipe is coaxially fixedly connected to the upper end of the support pipe. An air injection pipe is installed at the middle and lower end of the connecting pipe, and the open end of the air injection pipe extends seamlessly to the outside of the tower body. The upper end of the connecting pipe is connected to the spray plate via a threaded transmission mechanism, and the threaded transmission mechanism includes a support frame coaxially installed inside the spray plate. An intermittent purification mechanism is provided between the mounting cover, the exhaust seat, and the support pipe, and the intermittent purification mechanism includes a driven gear and a driving gear located inside the mounting cover.

[0011] Preferably, the threaded transmission mechanism further includes a drive shaft disposed inside the connecting pipe, the lower end of the support frame extends coaxially into the upper end of the connecting pipe through a sealed bearing, and the lower end of the support frame is sleeved on the outer side of the upper end of the drive shaft, and the inner side of the lower end of the support frame is connected to the outer side of the upper end of the drive shaft through a twisted thread.

[0012] Preferably, a square piston block is provided in the middle of the drive shaft, the connecting pipe has an outer circle and an inner square structure, and the outer side of the connecting pipe is fixedly connected to the inner side of the tower body by connecting arms distributed at equal angles. The square piston block is connected to the inner side of the connecting pipe in a seamless sliding connection manner, and the center of gravity of the drive shaft is located on the piston block.

[0013] Preferably, the outer side of the driving gear has a set of driven gears distributed at equal angles, the number of which corresponds to the number and position of the exhaust seats, and adjacent driven gears in the same set mesh with each other. The driving gear meshes with the driven gear closest to it. The inner bottom surface of the mounting cover is bearing a mounting shaft with a number and position corresponding to the driven gears, and the driven gear is keyed to the outer side of the corresponding mounting shaft. The inner bottom surface of the mounting cover is also bearing a support shaft, and the driving gear is keyed to the outer side of the support shaft. The support shaft passes through to the inner side of the support tube via a sealed bearing.

[0014] Preferably, the outer side of the portion of the support shaft extending into the inner side of the support tube is connected to a driven tube via a one-way bearing, and a drive tube is sleeved on the outer side of the driven tube. The inner side of the drive tube is also connected to the outer side of the driven tube via a twisted thread, and the drive tube is coaxially fixedly connected to the lower end of the drive shaft. The drive shaft coaxially passes through the upper end of the support tube, and the upper end of the support tube is connected to the connecting tube through vent holes distributed at equal angles. A torsion spring is provided between the inner side of the lower end of the driven tube and the upper surface of the mounting cover.

[0015] Preferably, the intermittent purification mechanism further includes an air-blocking ring disposed inside the support pipe, and the air-blocking ring is provided with through holes penetrating both sides thereon. Two sets of pressure-bearing blocks are disposed inside the air-blocking ring, and two pressure-bearing blocks are disposed in each set. A toggle block is disposed between the two pressure-bearing blocks in the same set, and the toggle block is fixedly connected to the lower outer side of the driven pipe.

[0016] Preferably, the outer side of the air-blocking ring is seamlessly slidably connected to the inner side of the support tube, so as to block the connection between the support tube and the exhaust seat.

[0017] Preferably, the inner side of the support tube is connected to two centrally symmetrical sleeves, and the inner side of the opening end of each sleeve is into which a corresponding sleeve rod front end extends. The rear end of the sleeve rod is connected to the inner side of the air-blocking ring, and a spring is provided between the front end of the sleeve rod and the inner end of the corresponding sleeve.

[0018] Preferably, the upper end of the mounting shaft passes through the mounting cover and the exhaust seat in sequence via a sealed bearing to the top of the exhaust seat, and a diffuser impeller is installed on the outer side of the mounting shaft portion above the exhaust seat. The upper part of the exhaust seat is provided with a one-way exhaust hole that passes through both sides, and the one-way exhaust hole is set at an equal angle with respect to the corresponding mounting shaft.

[0019] Compared with the prior art, the beneficial effects of the present invention are: when the exhaust gas comes into contact with the purification liquid inside the tower and forms bubbles, the spray-type fiberglass purification tower can cut the formed bubbles into dense microbubbles, thereby increasing the contact area between the purification liquid and the exhaust gas, which helps to improve the purification efficiency. In addition, the spray plate rotates back and forth when spraying the purification liquid, which can prevent the exhaust gas from overflowing from the blind area of ​​the spray, thus ensuring the purification effect.

[0020] 1. When exhaust gas is injected into the connecting pipe through the injection pipe, the exhaust gas accumulates in the connecting pipe, gradually generating a large positive pressure. This causes the piston block and its connected drive shaft to move upwards. As the drive shaft moves upwards, the drive pipe coaxially connected to its lower end moves upwards simultaneously. The upward movement of the drive pipe drives the driven pipe to rotate, causing the torsion spring to accumulate elastic potential energy. The rotation of the driven pipe causes its connected actuating block to gradually approach the pressure block until the actuating block contacts the pressure block and drives the air-blocking ring to rotate a certain angle. During this process, the spring is first compressed and then released, causing the through hole on the air-blocking ring to rotate and connect with the exhaust seat. At this moment, the exhaust gas in the connecting pipe instantly enters the exhaust seat, thus allowing the exhaust gas in the connecting pipe to pass through. As the air pressure drops instantaneously, the torsion spring releases its accumulated elastic potential energy, causing the driven tube to rotate in the opposite direction. This, in turn, drives the support shaft to rotate via the one-way bearing. As the support shaft rotates, the drive gear connected to it rotates synchronously, and the driven gear meshing with the drive gear rotates at high speed. This, in turn, drives the diffuser impeller to rotate at high speed via the mounting shaft. The exhaust gas entering the exhaust seat is discharged into the purification liquid inside the tower body through the one-way exhaust hole. When the exhaust gas first enters the purification liquid, it forms large bubbles. At this time, due to the high-speed rotation of the diffuser impeller, the large bubbles can be cut into dense microbubbles, thereby increasing the surface area of ​​contact between the exhaust gas and the purification liquid, which helps to improve the efficiency of the purification liquid in purifying the exhaust gas.

[0021] 2. During the reciprocating movement of the drive shaft, the support frame will be driven to rotate back and forth, which in turn will drive the spray plate to rotate back and forth. When the spray plate rotates back and forth, it can greatly reduce the blind zone of spraying, which means that it can prevent exhaust gas from overflowing from the blind zone, thus ensuring the effect of purifying exhaust gas.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0037] Please see Figures 1-13 The present invention provides the following technical solution:

[0038] Example 1: To address the problem of fixed nozzle positions in traditional spray-type fiberglass purification towers, which easily lead to spray blind spots and allow exhaust gas to overflow, resulting in poor purification effects, the following technical solution is provided: A spray-type fiberglass purification tower includes a tower body 1 and a drain port 3 located at its lower part. An exhaust port 2 is located at the top of the tower body 1, and a spray plate 10 for purifying exhaust gas is connected to the upper middle part of the tower body 1 via a bearing. A water-absorbing layer 6 is installed inside the exhaust port 2 at the top of the tower body 1, and a gas collecting plate 23 is provided between the water-absorbing layer 6 and the spray plate 10. The gas collecting plate 23 is installed on the inner side of the tower body 1 via support arms 12 evenly distributed on its outer side. An inlet pipe 4 is installed on the gas collecting plate 23, and the open end of the inlet pipe 4 is seamlessly connected to it. To the outside of the tower body 1, the gas collecting plate 23 is connected to the spray plate 10 through a liquid delivery hose 24 set at equal angles on its outer side. The lower surface of the spray plate 10 is provided with spray holes for spraying. The inner bottom surface of the tower body 1 is provided with a mounting cover 8 through the mounting base 7. The upper surface of the mounting cover 8 is coaxially fixedly connected to a support pipe 22. The upper surface of the mounting cover 8 is provided with an exhaust seat 9 that is connected to the outside of the support pipe 22 at equal angles. The upper end of the support pipe 22 is coaxially fixedly connected to a connecting pipe 25. The middle and lower end of the connecting pipe 25 is installed with an air injection pipe 5 that is connected to it. The open end of the air injection pipe 5 is seamlessly connected to the outside of the tower body 1. The upper end of the connecting pipe 25 is connected to the spray plate 10 through a threaded transmission mechanism. The threaded transmission mechanism includes a support frame 27 coaxially installed inside the spray plate 10.

[0039] The threaded transmission mechanism also includes a drive shaft 11 disposed inside the connecting pipe 25. The lower end of the support frame 27 extends coaxially into the upper end of the connecting pipe 25 through a sealed bearing, and the lower end of the support frame 27 is sleeved on the outer side of the upper end of the drive shaft 11. The inner side of the lower end of the support frame 27 is connected to the outer side of the upper end of the drive shaft 11 through a twisted thread. A square piston block is disposed in the middle of the drive shaft 11. The connecting pipe 25 has an outer circle and an inner square structure, and the outer side of the connecting pipe 25 is fixedly connected to the inner side of the tower body 1 through connecting arms 13 distributed at equal angles. The square piston block is connected to the inner side of the connecting pipe 25 by a seamless sliding connection, and the center of gravity of the drive shaft 11 is located on the piston block. The outer side of the drive gear 15 has sets of driven gears 14 distributed at equal angles, the number of which corresponds to the number and position of the exhaust seats 9. Adjacent driven gears 14 in the same set mesh with each other. The drive gear 15 meshes with the driven gear 14 closest to it. The inner bottom surface of the mounting cover 8 is bearing-mounted with mounting shafts 16 corresponding to the driven gears 14 in number and position. The driven gears 14 are keyed to the outer side of the corresponding mounting shafts 16. The inner bottom surface of the mounting cover 8 is also bearing-mounted with a support shaft 17, and the drive gear 15 is keyed to the outer side of the support shaft 17. The support shaft 17 extends through the inner side of the support tube 22 through a sealed bearing. The outer side of the portion of the support shaft 17 extending into the inner side of the support tube 22 is connected to a driven tube 19 through a one-way bearing. A drive tube 20 is sleeved on the outer side of the driven tube 19. The inner side of the drive tube 20 and the outer side of the driven tube 19 are also connected by a twisted thread. The drive tube 20 is coaxially fixedly connected to the lower end of the drive shaft 11. The drive shaft 11 coaxially extends through the upper end of the support tube 22. The upper end of the support tube 22 is connected to the connecting tube 25 through vent holes 28 distributed at equal angles. A torsion spring 21 is provided between the inner side of the lower end of the driven tube 19 and the upper surface of the mounting cover 8.

[0040] according to Figures 8-9 When in use, the air injection pipe 5 is connected to an external device for injecting waste gas, and the waste gas is injected into the interior of the connecting pipe 25 through the air injection pipe 5;

[0041] Meanwhile, the liquid inlet pipe 4 is connected to the external equipment for injecting purification liquid, so that the purification liquid enters the gas collecting plate 23 through the liquid inlet pipe 4, and is injected into the spray plate 10 through the liquid delivery hose 24, and finally sprayed out through the spray holes on the lower surface of the spray plate 10.

[0042] Because the passage between the exhaust seat 9 and the support pipe 22 is blocked by the air-blocking ring 29, the exhaust gas accumulates in the connecting pipe 25, which increases the pressure in the connecting pipe 25 and causes the drive shaft 11 to move upward under the action of the square piston block.

[0043] When the drive shaft 11 moves upward, it causes the support frame 27 and the spray disc 10 connected to it to rotate through the twisted thread connection with the support frame 27.

[0044] When the spray plate 10 rotates, it causes the trajectory of the purification liquid sprayed from the spray nozzles to change, which greatly reduces the blind zone of the spray, so that the exhaust gas cannot overflow through the blind zone, thus ensuring the purification effect of the exhaust gas.

[0045] Example 2: To solve the problem that the purification liquid inside the tower body 1 cannot fully contact the exhaust gas during the use of the previous spray-type FRP purification tower, resulting in poor exhaust gas purification efficiency, the following technical solution is provided: Specifically, an intermittent purification mechanism is provided between the mounting cover 8, the exhaust seat 9 and the support pipe 22, and the intermittent purification mechanism includes a driven gear 14 and a driving gear 15 installed inside the mounting cover 8.

[0046] The intermittent purification mechanism also includes a blocking ring 29 disposed inside the support pipe 22, and the blocking ring 29 is provided with through holes penetrating both sides thereon. Two sets of pressure-bearing blocks 30 are disposed inside the blocking ring 29, with two blocks in each set. A actuating block 31 is disposed between the two pressure-bearing blocks 30 in the same set, and the actuating block 31 is fixedly connected to the lower outer side of the driven pipe 19. The outer side of the blocking ring 29 is seamlessly slidably connected to the inner side of the support pipe 22, used to block the communication between the support pipe 22 and the exhaust seat 9. Two centrally symmetrical sleeves are axially connected to the inner side of the support pipe 22. The tube 32 has a corresponding sleeve rod 33 extending into the inner side of the open end of each sleeve 32. The rear end of the sleeve rod 33 is connected to the inner side of the air-blocking ring 29. A spring 34 is provided between the front end of the sleeve rod 33 and the inner end of the corresponding sleeve 32. The upper end of the mounting shaft 16 passes through the mounting cover 8 and the exhaust seat 9 in sequence through the sealing bearing to the top of the exhaust seat 9. An air-dispersing impeller 18 is installed on the outer side of the mounting shaft 16 above the exhaust seat 9. The upper part of the exhaust seat 9 is provided with a one-way exhaust hole 26 that passes through both sides. The one-way exhaust hole 26 is set at an equal angle with respect to the corresponding mounting shaft 16.

[0047] according to Figures 4-13 As the drive shaft 11 moves upward, the drive tube 20 connected to its lower end moves relative to the driven tube 19, thereby driving the driven tube 19 to rotate.

[0048] Furthermore, the torsion spring 21 installed between the driven tube 19 and the mounting cover 8 gradually accumulates elastic potential energy;

[0049] During the rotation of the driven tube 19, the actuating block 31 connected to it gradually approaches the pressure block 30 in the direction of rotation until the actuating block 31 and the pressure block 30 come into contact and squeeze the pressure block 30, causing the air-blocking ring 29 to rotate.

[0050] After the air-blocking ring 29 rotates, the part where the exhaust seat 9 and the support pipe 22 are connected is reconnected. At this time, the exhaust gas in the connecting pipe 25 instantly enters the exhaust seat 9, and the pressure in the connecting pipe 25 instantly decreases, causing the driven pipe 19 to rotate in the opposite direction under the action of the elastic potential energy released by the torsion spring 21. At this time, the driven pipe 19 drives the support shaft 17 to rotate through the one-way bearing.

[0051] When the support shaft 17 rotates, it drives the drive gear 15 connected to it to rotate. Since the drive gear 15 is meshed with the driven gear 14, the driven gear 14 and its connected mounting shaft 16 rotate at high speed.

[0052] When the mounting shaft 16 rotates at high speed, the diffuser impeller 18 connected to it will also rotate at high speed. At the same time, the exhaust gas entering the exhaust seat 9 is discharged into the purification liquid in the tower body 1 through the one-way exhaust hole 26. At the moment the exhaust gas comes into contact with the purification liquid, large bubbles are formed. Because the diffuser impeller 18 rotates at high speed, it can cut the large bubbles into dense micro bubbles, thereby greatly increasing the contact area between the exhaust gas and the purification liquid, and thus improving the efficiency of exhaust gas purification.

[0053] When the driven tube 19 rotates in the reverse direction, the actuating block 31 rotates in the reverse direction and gradually approaches another pressure block 30, thereby driving the air-blocking ring 29 to rotate in the reverse direction at a certain angle, causing the air-blocking ring 29 to block the passage between the exhaust seat 9 and the support tube 22 again.

[0054] Then, repeat the above process;

[0055] During the rotation of the aforementioned air-blocking ring 29 at a certain angle, the spring 34 will be compressed and then released, thereby intermittently connecting the exhaust seat 9 and the support pipe 22.

[0056] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
