Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, and in particular to a composite high-efficiency water mist removal tower. Background Technology

[0002] With societal development, various processing technologies across industries are constantly being upgraded and improved, especially water treatment processes, which are widely used. However, while these processes efficiently treat industrial products or pollutants, the ineffectiveness of conventional demisting equipment or components at the downstream end leads to water mist containing secondary pollutants entering subsequent processing equipment and the atmosphere, causing equipment corrosion and environmental pollution. According to incomplete statistics, over 4 million tons of steel are consumed annually due to corrosion, resulting in the scrapping and waste of over 400 million tons of steel products. China is a major importer of iron ore, currently incurring over $100 billion in import costs annually. Reducing equipment corrosion and extending product lifespan, thus addressing steel consumption at its source, would be beneficial for both enterprises and the national economy.

[0003] Furthermore, the water mist may contain various corrosive substances or microorganisms. For example, the water mist at the downstream end of spray towers in the electroplating industry contains large amounts of sodium salts, strong acids, or strong alkalis. These substances, when introduced into downstream equipment, can corrode the internal structure and shell, affecting the equipment's processing efficiency and lifespan. In more severe cases, it can lead to air leaks and structural collapse. When this type of water mist is released into the atmosphere, the corrosive substances can enter the respiratory tract and adhere to the moist mucous membranes, causing severe irritation to the upper respiratory tract and bronchi. If it enters the lungs, it can even lead to pneumonia, pulmonary edema, and acute respiratory failure.

[0004] The microorganisms in water mist containing microorganisms have a significant impact on downstream processing systems, human health, and the environment. When this water mist enters downstream processing systems and pipelines, the microorganisms continuously grow in the gaps, reducing ventilation area and exacerbating corrosion of the equipment's internal structure, leading to increased system operating resistance and a shorter lifespan. If this water mist enters the environment and is inhaled, it may cause allergic reactions or respiratory infections.

[0005] Currently, more than 20% of my country's total steel consumption is wasted annually due to corrosion, and the corrosion problem of steel structures is becoming increasingly prominent. Therefore, the development of composite high-efficiency water mist removal towers is of great significance for water mist treatment in various industries and for social development.

One end of the centrifugal blades is connected to the first drive shaft, and the other end of the centrifugal blades is in a free state.

[0027] like Figure 1 As shown, this invention discloses a composite high-efficiency water mist removal tower, which features stable operation, high water mist removal rate, and simple operation.

[0028] This water mist removal tower comprises a ring-shaped novel mesh demisting unit 5, a gas cooling unit 13, a hollow multi-faceted spherical packing demisting unit 6, a porous foamed surface-reinforced mesh demisting unit 7, a demisting unit with porous arc-hook plate-type baffles 8, a centrifugal demisting unit 9, a mechanical tray regeneration demisting unit 10, a tube bundle type ion terminal demisting unit 12, and a gas cooling unit 13. It comprehensively utilizes the advantages of various technologies, making it suitable for various water mist-containing gases and achieving higher demisting efficiency.

[0029] The water mist removal tower also includes a silent spray pump 1, a drain pipe 2, a maintenance window 4, an air intake auxiliary system 3, and a silent backwashing unit 11.

[0030] This invention employs a silent backwashing unit 11 and a drain pipe 2, which can maintain efficient demisting function for a long time and reduce manual maintenance. Its successful development and improvement can extend the service life of an enterprise's environmental protection system, save operating and maintenance costs, and generate significant economic and social benefits.

[0031] The annular novel mesh demisting unit 5 includes an annular porous foamed surface-reinforced mesh 19. The air inlet auxiliary system 3 includes a porous plate 15, which is located at the rear end of the air inlet auxiliary system 3 and is aligned with the annular porous foamed surface-reinforced mesh 19. The upper and lower surfaces 16 of the air inlet auxiliary system 3 are sealed, while the left and right sides are open. The front end of the air inlet auxiliary system 3 is connected to the tower wall of the composite high-efficiency water mist removal tower, and there is an opening in the tower wall. The front end of the air inlet auxiliary system 3 connects to the water mist-containing gas inlet pipe through this opening. The system is connected, and the water mist-containing gas enters the water mist removal tower from the front end of the air intake auxiliary system 3. Then, part of the water mist-containing gas enters the annular porous foamed surface strengthening mesh 19 through the porous plate 15 on the front side, and part of the water mist-containing gas enters the annular porous foamed surface strengthening mesh 19 through the left and right sides of the air intake auxiliary system 3. The front end of the air intake auxiliary system 3 is smaller and the rear end is larger, which is funnel-shaped and facilitates the flow of water mist-containing gas. The structure of the air intake auxiliary system 3 ensures that the water mist-containing gas passes through the annular porous foamed surface strengthening mesh 19 evenly.

[0032] like Figure 2 As shown, the annular novel mesh defogging unit 5 includes an annular sealed plate 14, and the annular porous foamed surface-reinforced mesh 19 is installed on the annular sealed plate 14.

[0033] The water mist-containing gas first passes through the air inlet auxiliary system 3 (flow guide). The air inlet of the air inlet auxiliary system 3 is connected to the air inlet duct. The front air inlet surface uses a perforated plate 15 with a low flow rate. The top and bottom surfaces are sealed, while the left and right sides are open, allowing airflow that cannot pass through the front to enter the annular novel mesh demisting unit 5 evenly from all sides. The gas can quickly pass through the annular porous foamed surface reinforced mesh 19. The annular porous foamed surface reinforced mesh 19 uses a perforated plate filled with porous foam material. Compared with traditional PP wire mesh, PP wire mesh has the disadvantage of large pressure drop and is prone to carrying out mesh fibers after repeated washing and shaking, reducing the demisting effect. The perforated plate filled with porous foam material has the advantage of intercepting large water droplets at high speed without carrying out solid waste such as mesh fibers. The increased flow area and decreased wind speed of the airflow further improve the processing effect of subsequent processes.

[0034] Afterwards, the gas containing water mist enters the hollow multifaceted spherical packing demister unit 6. Large droplets containing particulate matter will collide with the hollow multifaceted packing spheres and fall to the bottom of the tower or into the packing spheres due to gravity. The packing spheres have large gaps, which can reduce the blockage of the packing by particulate matter or microorganisms.

[0035] like Figure 3 As shown, the porous foamed surface-reinforced mesh defogging unit 7 includes a porous plate 17 with surface-reinforced treatment, and the porous plate 17 with surface-reinforced treatment is filled with porous foamed material 18.

[0036] The gas containing water mist then enters the porous foamed surface reinforced mesh demisting unit 7. Traditional PP wire mesh, besides its large pressure drop, is prone to having its wires pulled out after repeated washing and shaking, reducing its demisting effect. The invented porous foamed surface reinforced mesh demisting unit 7, however, fills a porous plate 17 with porous foam material 18 and undergoes surface reinforcement treatment, achieving a demisting effect close to that of traditional PP wire mesh without its drawbacks. Smaller liquid droplets entrained in the gas phase encounter the porous foamed surface reinforced mesh demisting unit 7 and are adhered to or adsorbed. Through repeated adsorption of droplets, the extremely small droplets agglomerate and accumulate into larger droplets, which then fall off.

[0037] like Figure 4 , 5 As shown, the demisting unit 8 with a perforated arc hook plate includes a baffle plate 21 and an arc-shaped perforated hook plate 20, wherein the arc-shaped perforated hook plate 20 is connected to the baffle plate 21.

[0038] The water mist-laden gas then enters the demisting unit 8 with a porous arc-hook plate type baffle. When the water mist-laden gas passes through the baffle 21 at a certain angular velocity, the water mist impacts the baffle 21 due to the sudden change in airflow direction. However, traditional baffles have low demisting efficiency, and the efficiency gradually decreases as the water mist particle size decreases. While the hook-plate type baffle has better demisting efficiency, the added hook increases the pressure drop. The demisting unit 8 with a porous arc-hook plate type baffle of the present invention combines the advantages of traditional baffles and hook-plate type baffles. It improves the hook type by replacing the original straight plate with an arc-shaped porous hook plate 20 to reduce wind resistance. Furthermore, it adjusts the number and diameter of the holes in the arc-shaped porous hook plate 20 according to the air intake and pressure loss to achieve optimal results. After the water-containing mist gas finally passes through, the mist droplets are intercepted and adsorbed onto the surfaces of the baffle plate 21 and the arc-shaped porous hook plate 20 to form mist droplets. When a certain amount is formed, it will separate from the surfaces of the baffle plate 21 and the arc-shaped porous hook plate 20.

[0039] like Figure 6 As shown, the centrifugal demisting unit 9 includes centrifugal blades 28 and a first drive shaft 29. One end of the centrifugal blades 28 is connected to the first drive shaft 29, and the other end of the centrifugal blades 28 is in a free state. The first drive shaft 29 drives the centrifugal blades 28 to rotate at high speed to achieve the purpose of removing water mist.

[0040] like Figure 7As shown, the mechanical tray regeneration demisting unit 10 includes a scraper 30, a second drive shaft 31, a mechanical tray 32, a differential 33, and a motor. The mechanical tray 32 is provided with sponge filler. The motor is connected to the second drive shaft 31 through the differential 33. The mechanical tray 32 is connected to the second drive shaft 31. The sponge filler is demisted by the scraper 30.

[0041] After the gas containing water mist enters the centrifugal demisting unit 9, the first drive shaft 29 and the second drive shaft 31 of the mechanical tray regeneration demisting unit 10 are the same. Due to the heavier weight of the mechanical tray regeneration demisting unit 10 and the effect of the differential 33, the mechanical tray 32 will rotate at a lower speed, while the centrifugal demisting unit 9 will rotate at a higher speed. This causes the fine water mist to be separated by the high-speed rotating mesh plate under the action of centrifugal force, adhere to the inner edge of the tower body, and then slide down to the bottom of the tower body.

[0042] Gas containing water mist passes through the mechanical tray regeneration demisting unit 10, where the water in the gas is demisted by the sponge packing of the mechanical tray 32. The mechanical tray regeneration demisting is divided into a reaction zone and a regeneration zone. The regeneration zone uses a fixed semi-elliptical scraper 30. When the sponge packing rotates at a constant speed, the sponge packing removes water mist by passing through the scraper 30. The reaction and regeneration are carried out simultaneously.

[0043] like Figure 8 As shown, the tubular ion terminal demisting unit 12 includes a tubular electrode cylinder 35 and a tubular high-voltage electrode 36, with the tubular high-voltage electrode 36 disposed inside the tubular electrode cylinder 35.

[0044] After passing through multiple processes, the water-mist-containing gas enters the tube bundle ion demister unit 12 for end-of-line demisting. The gas is left with only a small amount of water mist and fine droplets. To improve demisting efficiency, the tube bundle ion demister adopts an S-curve channel, using a particle stream formed by a high-energy particle beam to randomly impact the droplets and small amount of water mist, thus achieving the demisting effect.

[0045] The tube bundle ion demister unit 12 is installed at the tower outlet. The tube bundle ion demister unit 12 has a double-layer shell, with the inner layer made of stainless steel 304 and the outer layer made of PP material. The interior is divided into double-layer electrodes. The gas containing water mist enters the right half of the tube bundle ion demister layer 37 and then passes through the left half of the tube bundle ion demister layer 34. The gas passage is S-shaped.

[0046] like Figure 9As shown, the silent backwashing unit 11 includes a silent spray pump 1, a high-pressure nozzle 22, a high-pressure pipe 23, and a sound-absorbing housing 24. The silent spray pump 1 is installed inside the sound-absorbing housing 24. The silent spray pump 1 is connected to the high-pressure pipe 23. Multiple high-pressure nozzles 22 are installed on the high-pressure pipe 23. The sound-absorbing housing 24 is provided with a heat dissipation port 25. A shock-absorbing device 26 is provided at the bottom of the sound-absorbing housing 24.

[0047] like Figure 10 As shown, the water mist removal tower includes an inlet pipe 101 and an outlet pipe 102. One end of the inlet pipe 101 is connected to the gas cooling unit 13, and the other end of the inlet pipe 101 is connected to the hollow multifaceted spherical packing demisting unit 6. One end of the outlet pipe 102 is connected to the gas cooling unit 13, and the other end of the outlet pipe 102 is connected to the hollow multifaceted spherical packing demisting unit 6.

[0048] The hollow multifaceted spherical packing demisting unit 6 includes a spiral cooling pipe 103 and a multifaceted hollow packing 104 located on the spiral cooling pipe 103. The gas cooling unit 13 includes a cooling tower hot water zone 131, a lift water pump 132, a cooling tower cold water zone 133, a cooling tower grid zone 134, a lift water pipe 135, and a cooling fan 136. The water temperature in the inlet pipe 101 is low, while the temperature of the water mist-containing gas is high. The water in the inlet pipe 101 can be used to cool the gas (heat exchange will occur), and the water mist in the gas will condense into water droplets, thus achieving the purpose of removing water mist. After heat exchange, the water temperature in the water pipe will rise, and the water will return to the gas cooling unit 13 through the outlet pipe 102. After being cooled by the gas cooling unit 13, the water will enter the hollow multifaceted spherical packing demisting unit 6 through the inlet pipe 101.

[0049] After the equipment has been running for a period of time, the internal high-pressure nozzles 22 are opened to thoroughly clean each demisting unit, preventing the accumulation of particulate matter and microorganisms that could clog the demisting layer. A drain pipe 2 is installed at the bottom of the tower, allowing for automatic drainage or, after the backwashing process, draining all liquid inside the tower. To enhance environmental protection, the silent backwashing unit 11 is equipped with a sound-absorbing outer shell 24. The outer shell 24 is made of 2-3mm thick high-quality cold-rolled electrolytic steel plate combined with multiple layers of damping sound insulation material. The surface is electrostatically sprayed, and the spaces between the shells are filled with sound insulation boards, damping boards, environmentally friendly sound-absorbing cotton, etc., ensuring that the noise level of the silent backwashing unit 11 at one meter is ≤55dB while guaranteeing the required airflow for heat dissipation. Using the above process ensures effective removal of water mist from the gas.

[0050] This invention offers the following advantages: 1. High processing efficiency, effectively removing water mist; 2. High degree of automation, requiring no dedicated personnel for management and daily maintenance, only periodic inspections; 3. No need to add other chemicals, no secondary pollution, and low operating costs; 4. Long service life, with reasonable utilization of combined processes significantly reducing water mist damage to equipment; 5. Wide applicability, capable of removing water mist in water-bearing processes across various industries; 6. Strong ability to combine with other processes, and can be manufactured in vertical or horizontal shapes depending on site and process requirements.

[0051] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
