Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a chemical fiber waste gas purification spray tower. Background Technology

[0002] In the production of chemical fibers, processes such as spinning, polymerization, and heat setting generate large amounts of industrial waste gas containing volatile organic compounds (such as styrene and caprolactam), acidic gases (such as hydrogen sulfide and sulfur dioxide), and fiber dust. If this waste gas is discharged directly without effective treatment, it will not only cause air pollution but also pose a serious threat to the surrounding ecological environment and the respiratory health of operators.

[0003] As a mature gas-liquid contact waste gas purification device, spray towers are widely used in the purification of chemical fiber waste gas due to their advantages such as relatively simple structure, high purification efficiency, and low operating costs. To increase the contact area between the waste gas and the purification liquid (such as alkaline absorbent or organic solvent absorbent), and to enhance the absorption and neutralization of pollutants, existing chemical fiber waste gas purification spray towers typically have multiple packing layers arranged along the height inside the tower shell. These packing layers are filled with spherical packing material—mostly plastic or metal. Due to their smooth surface and uniform porosity, these spherical packing materials allow the treatment liquid to better form a liquid film on the surface and reduce the resistance to waste gas flow. During operation, the treatment liquid is atomized by the spray components at the top of the tower and flows downwards through the packing layers, forming a uniform liquid film on the surface of the spheres. The chemical fiber waste gas is introduced from the bottom inlet and passes through each packing layer from bottom to top, fully contacting the liquid film. Pollutants in the waste gas are adsorbed, dissolved, or removed by chemical reactions by the treatment liquid, ultimately achieving purified emissions that meet standards.

[0004] However, the spherical packing layer is more prone to a series of problems during long-term operation, requiring regular replacement: On the one hand, fiber dust carried in the chemical fiber waste gas tends to accumulate in the gaps between the spheres—because the spheres are in point contact, dust is easily trapped in the gaps, and reaction products in the treatment liquid may precipitate and adhere to the surface of the spheres. As the usage time increases, the spherical packing is prone to local blockage, resulting in uneven airflow distribution in the tower and a significant decrease in purification efficiency; On the other hand, acidic or alkaline substances in the chemical fiber waste gas can corrode the spherical packing, especially plastic spheres, which are prone to aging and deformation after long-term immersion in the treatment liquid, while ceramic spheres may experience surface peeling due to corrosion, which not only weakens the gas-liquid contact effect, but the broken sphere debris may also be discharged with the airflow, causing secondary pollution.

[0005] Currently, most chemical fiber exhaust gas purification spray towers on the market adopt an overall closed structure. The spherical packing layer is usually supported by a grid plate fixed to the inner wall of the tower shell. The grid plate and the tower shell are mostly welded or bolted together to form a relatively closed internal space. This structural design makes replacing the spherical packing layer more challenging: The entire spray tower must be stopped before replacement, and any remaining treatment liquid and waste gas must be purged. Then, the inspection flange covers on the top or side of the tower shell must be removed. Because the spherical packing is loose and the inspection port is limited in size, operators must reach through the narrow port or use simple tools to retrieve the spheres one by one. This is not only extremely labor-intensive but also prone to causing spheres to get stuck in corners of the tower shell, resulting in longer replacement times. Simultaneously, residual harmful waste gas in the tower can easily evaporate during operation, increasing the risk of poisoning for operators. Furthermore, improper disassembly of the grating can easily lead to deformation of the grating or detachment of welds on the inner wall of the tower shell. Reinstallation requires repair of the tower, further increasing equipment maintenance costs and downtime, severely impacting the normal production schedule of chemical fiber enterprises.

[0006] In summary, existing chemical fiber exhaust gas purification spray towers suffer from technical pain points due to limitations in their closed structure and the fixed support method of the spherical packing layer. These pain points include greater difficulty in replacing the spherical packing, lower efficiency, higher safety risks, and higher maintenance costs. There is an urgent need for a spray tower structural design that can simplify the replacement process of the spherical packing, improve replacement efficiency, and ensure operational safety, so as to meet the needs of chemical fiber enterprises for efficient and stable exhaust gas treatment.

[0013] An air supply pipe is fixedly installed on the tower shell assembly. The top end of the air supply pipe is located below a bottom orifice plate and below a baffle. Multiple addition pipes are fixedly installed on the tower shell assembly. Each orifice plate has an addition pipe above it, and each addition pipe is detachably fitted with a sealing cap.

[0014] Preferably, the liquid delivery assembly includes a second pump body and a connecting pipe assembly; the second pump body is fixedly installed on the outer surface of the lower housing, and the second pump body is fixedly connected to a third connecting pipe through the connecting pipe assembly.

[0015] Preferably, a rotating ring is rotatably connected to the top edge of each of the orifice plates, and an annular tube is fixedly installed on the upper surface of the rotating ring. The annular tube is rotatably connected to the inner surface of the tower shell assembly. The annular tubes at different heights are fixedly connected by multiple second connecting tubes. Multiple nozzles are fixedly installed at equal intervals in the circumferential direction of each annular tube.

[0016] The connecting pipe assembly includes a liquid outlet head, a main pipe, and a connecting pipe. The liquid outlet head is fixedly installed on the liquid outlet end of the second pump body, the main pipe is fixedly installed on one end of the liquid outlet head, and one end of the main pipe is fixedly connected to the third connecting pipe through the connecting pipe.

[0017] The other end of the main pipe is connected to the inside of the annular pipe through a branch pipe. A first valve and a second valve are fixedly installed on both ends of the main pipe, and the connection end of the liquid outlet head to the main pipe is located between the first valve and the second valve.

[0018] The tower shell assembly is equipped with a rotating component that enables the rotating ring to rotate.

[0019] Preferably, the rotating assembly includes a motor, a gear ring, and a gear. The motor is fixedly mounted on the tower shell assembly, the gear is fixedly mounted on the output end of the motor, the gear ring is rotatably mounted on the tower shell assembly, and the gear ring is fixedly connected to the rotating ring, with the gear ring and the gear maintaining a meshing state.

[0022] Compared with the prior art, the present invention provides a chemical fiber waste gas purification spray tower, which has the following beneficial effects:

[0023] 1. When replacing old packing, there is no need to disassemble the tower shell or have personnel enter the tower. Simply start the second pump to drive the telescopic rod to extend. After the baffle disengages from the orifice plate, the packing can fall down layer by layer along the funnel-shaped orifice plate and be discharged through the air supply pipe. When adding new packing, after the baffle blocks the orifice plate, the material is directly fed through the addition pipe. The whole process is simple and efficient, greatly reducing the downtime of the spray tower, reducing the difficulty of replacing packing, ensuring and reducing pollution to the operating environment, and taking into account both environmental performance and operational safety.

[0024] 2. This spray tower utilizes a flushing system of "rotating annular pipe + multi-angle nozzles" and shares pipelines with the second pump body. The "baffle drive" and "orifice plate flushing" functions can be switched by valve switching. The motor drives the annular pipe to rotate, and the nozzles spray clean water in all directions. This can both impact and dislodge the bonded packing material, ensuring that the old packing material is completely discharged, and clean impurities on the orifice plate. This ensures that the exhaust gas passes smoothly through the orifice plate and fully contacts the treatment liquid, avoiding the problem of incomplete pollutant removal caused by orifice plate blockage. This further improves the environmental protection of the equipment and helps chemical fiber enterprises achieve emission standards for exhaust gas.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0038] Please combine Figures 1 to 7 As shown, the present invention provides a chemical fiber waste gas purification spray tower. The chemical fiber waste gas treatment device includes a tower shell assembly composed of a lower shell 1 and an upper shell 2. The top end of the lower shell 1 is fixedly connected to the bottom end of the upper shell 2 through multiple fixing blocks 3. Multiple perforated plates 4 are fixedly installed inside the tower shell assembly. The perforated plates 4 are configured in a funnel shape. The bottom end of the perforated plate 4 is provided with a through hole. Multiple perforated plates 4 are evenly distributed in the height direction of the tower shell assembly.

[0039] Each orifice plate 4 is equipped with a spray pipe assembly, which consists of spray pipes 5 and spray heads 6. There are multiple spray pipes 5, and the sizes of the multiple spray pipes 5 are different. The size of the inner spray pipe 5 is smaller than that of the outer spray pipe 5. The multiple spray pipes 5 are fixedly connected by fixing pipes. Multiple spray heads 6 are fixedly installed on each spray pipe 5, and the water outlet of the multiple spray heads 6 all face the orifice plate 4.

[0040] A first pump body 7 is fixedly installed on the outer surface of the tower shell assembly. A conveying pipe 8 is fixedly installed on the water outlet end of the first pump body 7. One end of the conveying pipe 8 is fixedly connected to the spray pipe 5. The first pump body 7 conveys the treatment liquid for purifying chemical fiber waste gas to the spray pipe 5. Finally, multiple spray heads 6 spray it onto the packing to purify the chemical fiber waste gas and achieve the effect of environmental protection.

[0041] It should be noted that each first connecting pipe 9 penetrates the interior of the orifice plate 4 and is fixedly connected to the orifice plate 4, thereby achieving a fixed connection of multiple orifice plates 4. Among the multiple orifice plates 4, the orifice plates 4 located at the top and bottom are fixedly connected to the inner surface of the tower shell assembly through multiple mounting rods.

[0042] A baffle 16 is provided directly below the bottom of each orifice plate 4. An elastic telescopic rod 17 is fixedly installed below each orifice plate 4 by a mounting block. The movable end of the elastic telescopic rod 17 is fixedly connected to the baffle 16. A telescopic rod 18 is also fixedly installed below each orifice plate 4. Multiple telescopic rods 18 at different heights are fixedly connected by a third connecting pipe 25. The third connecting pipe 25 penetrates the interior of the orifice plate 4 and is fixedly connected to the orifice plate 4. A solenoid valve is fixedly installed on the fixed end of each telescopic rod 18.

[0043] A second pump body 20 is fixedly installed on the outer surface of the tower shell assembly. The second pump body 20 is fixedly connected to the third connecting pipe 25 through the connecting pipe group. When the second pump body 20 is started, water can be delivered to the inside of the telescopic rod 18, which can extend the movable end of the telescopic rod 18. At this time, the baffle 16 is disengaged from the bottom through hole of the orifice plate 4.

[0044] An air supply pipe 12 is fixedly installed on the tower shell assembly. The top end of the air supply pipe 12 is located below a bottom perforated plate 4 and below a baffle 16. There is a gap between the top end of the air supply pipe 12 and the baffle 16, allowing the chemical fiber waste gas to be purified to enter the tower shell assembly smoothly. Multiple addition pipes 10 are fixedly installed on the tower shell assembly. Each perforated plate 4 has an addition pipe 10 above it. Each addition pipe 10 is detachably fitted with a sealing cap 11, which can be threaded to the top end of the addition pipe 10.

[0045] To ensure the treatment effect of the chemical fiber waste gas treatment device on chemical fiber waste gas, when replacing the new packing, water is delivered to the inside of the telescopic rod 18 using the liquid delivery component. Since multiple telescopic rods 18 are connected, after water enters the internal cavity of the telescopic rod 18, the movable end of the telescopic rod 18 extends out, and the baffle 16 is disengaged from the bottom through hole of the orifice plate 4. The packing on the higher orifice plate 4 falls downward and finally falls onto the lowest orifice plate 4. The packing on the lowest orifice plate 4 falls into the air delivery pipe 12. The bottom end of the air delivery pipe 12 is disconnected from the chemical fiber waste gas delivery pipe, and the packing can be discharged from the end of the air delivery pipe 12.

[0046] When adding new packing material, the baffle 16 is located directly below the through hole. Remove the sealing cap 11 on the adding pipe 10, and then put the new packing material into the adding pipe 10. This makes it easier to replace the packing material and enables the chemical fiber waste gas treatment device to maintain a strong chemical fiber waste gas treatment capacity and better environmental performance. Example

[0047] After prolonged use, a sticky substance easily forms on the surface of the packing material, which can prevent some of the packing material from entering the through holes of the orifice plate 4. To solve this problem, a rotating ring 13 is rotatably connected to the top edge of each orifice plate 4. An annular tube 14 is fixedly installed on the rotating ring 13 and is rotatably connected to the inner surface of the tower shell assembly. Annular tubes 14 at different heights are fixedly connected by multiple second connecting pipes 24. Multiple nozzles 15 are fixedly installed at equal intervals along the circumference of each annular tube 14.

[0048] The connecting pipe assembly includes a liquid outlet head 19, a main pipe 21, and a connecting pipe 29. The liquid outlet head 19 is fixedly installed on the liquid outlet end of the second pump body 20, the main pipe 21 is fixedly installed on one end of the liquid outlet head 19, and one end of the main pipe 21 is fixedly connected to the third connecting pipe 25 through the connecting pipe 29.

[0049] The other end of the main pipe 21 is connected to the inside of the annular pipe 14 through the branch pipe 30. The first valve 22 and the second valve 23 are fixedly installed on both ends of the main pipe 21 respectively. The connection end of the liquid outlet head 19 and the main pipe 21 is located between the first valve 22 and the second valve 23.

[0050] A motor 26 is fixedly installed on the tower shell assembly, and a gear 28 is fixedly installed on the output end of the motor 26. A gear ring 27 is rotatably installed between the top end of the lower shell 1 and the bottom end of the upper shell 2, and the gear ring 27 is fixedly connected to the rotating ring 13. The gear ring 27 and the gear 28 are in a meshing state.

[0051] After the second pump body 20 is turned on, water is delivered to the inside of the telescopic rod 18. After the movable end of the telescopic rod 18 extends, the baffle 16 is disengaged from directly below the through hole. At this time, only a part of the packing material falls into the air delivery pipe 12 by its own weight, while a part of the packing material is still stuck on the upper surface of the orifice plate 4, and there are many impurities on the orifice plate 4.

[0052] At this time, the first valve 22 is closed to keep the telescopic rod 18 extended, and the second valve 23 is opened. Water enters the interior of the annular pipe 14 through the branch pipe 30. Multiple annular pipes 14 are connected through the second connecting pipe 24, so water enters each annular pipe 14 and is sprayed out by multiple nozzles 15. In addition, the motor 26 drives the gear 28 to rotate, which in turn drives the gear ring 27 to rotate. The gear ring 27 is fixedly connected to an annular pipe 14. As a result, multiple annular pipes 14 rotate, so that the nozzles 15 can flush the impurities on the orifice plate 4 from all directions, keep the air holes on the orifice plate 4 unobstructed, and allow the chemical fiber waste gas to pass through the orifice plate 4 smoothly, ensuring the purification efficiency of the chemical fiber waste gas. It can also impact the packing material that is adhered to the orifice plate 4, so that all the packing material can enter the air delivery pipe 12 smoothly.

[0053] After the packing is completely discharged, the fixed end of the telescopic rod 18 is in an open state, the solenoid valve on the telescopic rod 18 is opened, and under the elastic force of the elastic telescopic rod 17, the baffle 16 returns to the bottom of the through hole, and the water inside the telescopic rod 18 is also discharged. A limit ring is fixedly installed on the inner surface of the telescopic rod 18 to limit the moving end of the telescopic rod 18, so that the water in the third connecting pipe 25 can smoothly enter the interior of the telescopic rod 18.

[0054] A drain pipe is fixedly installed on the bottom end of the lower housing 1, and a drain valve is fixedly installed on the drain pipe. The generated sewage is discharged through the drain pipe.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
