A waste gas purification tower for plant oil soapstock acidification

Abstract

This invention relates to the field of waste gas purification technology, specifically to a purification tower for acidified vegetable oil soap residue waste gas. The tower includes a tower body and an inlet pipe and a wastewater pipe connected to the outer wall of the tower body. An upper rack is fixedly connected to the inner wall of the tower body, and a lower rack is fitted to the inner wall of the tower body below the upper rack. A circular tube is rotatably installed through the center of the upper rack, and a cylindrical shell is fixedly connected to the lower end of the circular tube. When the packing material, with its surface fully coated with an anti-sticking agent, comes into contact with the acidified vegetable oil soap residue waste gas, the sticky substances in the waste gas are not easily adhered to the packing surface and are easily washed off by the alkaline solution. Furthermore, the agitated packing material further promotes the contact effect between the packing material and the waste gas and alkaline solution, thereby improving the neutralization reaction efficiency. The lower rack also vibrates continuously during use and comes into contact with the anti-sticking agent, effectively preventing clogging of the lower rack and thus improving the overall purification effect.

Description

Technical Field

[0001] This invention relates to the field of waste gas purification technology, specifically to a waste gas purification tower for acidification of vegetable oil soap residue. Background Technology

[0002] Vegetable oil soap residue is a major byproduct of vegetable oil refining, primarily composed of sodium fatty acid salts, residual oils, gums, pigments, and small amounts of impurities. To recover the fatty acids, an acidification process is typically used industrially: strong acid is added to the soap residue, and a displacement reaction converts the fatty acid salts into free fatty acids. This acidification process generates acidification waste gas, which, if directly emitted, causes air pollution. Therefore, the waste gas needs to be purified using a spray tower.

[0003] During the purification process, the exhaust gas enters through the inlet pipe of the spray tower, then floats upward inside the tower, passes through two sets of alkaline spray and the packing layer, and is then discharged from the top of the tower. The alkaline solution removes acidic gases through neutralization reaction, while capturing some viscous droplets and particulate matter. The packing increases the gas-liquid contact area and contact time, improving absorption efficiency, thereby purifying the exhaust gas.

[0004] However, the acidified exhaust gas from vegetable oil soap residue also contains viscous substances (such as fatty acid droplets and residual grease), which not only easily adhere to the surface of the packing material, but also tend to adhere to the bottommost grid that supports the packing material. This leads to two problems:

[0005] Firstly, the core function of the packing is to increase the gas-liquid contact area and time through a porous structure. When viscous substances adhere to the surface of the packing, they will block the pores and channels of the packing. Furthermore, the sprayed alkaline solution is difficult to wash away the viscous substances adhering to the surface of the packing, resulting in insufficient gas-liquid contact and directly leading to a decrease in the neutralization reaction efficiency.

[0006] Secondly, the bottom grille is the first to come into contact with the exhaust gas. If sticky substances accumulate on the bottom grille over a long period of time, it will reduce the flow cross-section of the grille, which can easily cause the exhaust gas to flow off course in the tower, thus reducing the overall purification effect. Summary of the Invention

[0007] The purpose of this invention is to provide a purification tower for acidified waste gas from vegetable oil soap residue, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a vegetable oil soap residue acidification waste gas purification tower, comprising a tower body and a smoke inlet pipe and a sewage pipe connected to the outer wall of the tower body.

A second spring is slidably sleeved on the outer wall of the connecting post. The second spring is fixedly connected between the conical block and the splicing block.

[0012] Preferably, the rotating mechanism includes two discs and two bevel gears. The two discs are symmetrically fixedly connected to the inner wall of the cylindrical tube, and a motor is fixedly installed between the two discs. A connecting rod is fixedly connected to the output shaft end of the motor. The connecting rod passes through the inner wall of the center of the lower disc and the inner wall of the upper end of the cylindrical shell in sequence. The lower end of the connecting rod is rotatably connected to the bottom end of the inner wall of the cylindrical shell. A bevel gear is fixedly sleeved at the lower edge of the outer wall of the connecting rod. The two bevel gears are respectively fixedly connected to the two cylindrical tubes at their close ends, and both bevel gears mesh with the bevel gears.

[0013] Preferably, the drive mechanism includes a support plate, a housing, and two bevel gears. The support plate is fixedly connected to the outer wall of the tower body, and a motor is fixedly installed at the upper end of the support plate. A long rod is fixedly connected to the output shaft end of the motor. The housing is slidably sleeved on the outer wall of the circular tube near the upper edge, and a support column is fixedly connected between the rear end of the housing and the inner wall of the tower body. The long rod is rotatably installed in the front inner wall of the housing. One of the bevel gears is fixedly connected to the end of the long rod away from the motor, and the other bevel gear is fixedly connected to the top end of the circular tube. The two bevel gears mesh with each other.

[0014] Preferably, the anti-sticking agent delivery mechanism includes a support frame and two conduits. The support frame is fixedly installed on the outer wall of the tower body, and a water pump and a storage tank are fixedly installed sequentially from front to back on the upper end of the support frame. A water pump is connected between the water inlet end of the water pump and the lower edge of the outer wall of the storage tank, and a delivery pipe is connected to the water outlet end of the water pump. The delivery pipe passes through the tower body and the outer shell sequentially, and the end of the delivery pipe away from the water pump passes through the inner wall of the center of a bevel gear one located on the circular tube. The upper ends of the two conduits are symmetrically fixedly installed in the inner wall of the upper disc, and both conduits pass through the lower disc. The lower ends of both conduits are connected to L-shaped pipes.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Through the coordinated operation of the upper and lower frame, circular tube, cylindrical shell, circular column, push pipe, one-way nozzle, rotating mechanism, drive mechanism, and anti-sticking agent delivery mechanism, the anti-sticking agent is sprayed out in a ring shape along the conical surface of the conical block, effectively expanding the spraying range. With the nozzle rotating around the center of the circular tube and rotating on its own axis, it can not only continuously turn over the packing between the upper and lower frame, but also evenly spray the anti-sticking agent into the packing. When the packing with the anti-sticking agent fully adhered to its surface comes into contact with the acidification waste gas of vegetable oil soap residue, the sticky substances in the waste gas are not easy to form stubborn adhesion on the surface of the packing and are easily washed off by the alkaline solution. Moreover, the turned packing can further promote the contact effect between the packing and the waste gas and alkaline solution, thereby improving the neutralization reaction efficiency.

[0018] 2. By setting up a vibration mechanism, the lower tray will vibrate continuously during use. Combined with the spraying of anti-sticking agent, the lower tray will also come into contact with the anti-sticking agent, which can effectively prevent the lower tray from clogging and thus improve the overall purification effect.

The ends of the horizontal sections of the two L-shaped tubes 36 are movably inserted through the ends of the two circular cylinders 40 that are far apart from each other.

[0035] The inner wall of the tower body 1 is fixedly installed with a main water pipe 7, and the outer wall of the main water pipe 7 is connected to multiple evenly distributed branch pipes 17. The main water pipe 7 and the multiple branch pipes 17 are all located above the upper frame 15.

[0036] Working principle: First, the waste gas conveying channel for acidification of vegetable oil soap residue is connected to the flue gas inlet pipe 3. The waste gas can enter the tower body 1 along the flue gas inlet pipe 3 and flow upward. There are many packing materials placed between the upper rack 15 and the lower rack 14. The main water pipe 7 is connected to the alkali conveying channel. The alkali solution will flow into the main water pipe 7 and multiple branch pipes 17, and be sprayed out from the nozzles on the multiple branch pipes 17. The alkali solution will wash the surface of the packing material. The waste gas will pass through the upper rack 15, the lower rack 14 and the packing material, and then upward through the sprayed alkali solution, the main water pipe 7 and the multiple branch pipes 17. Near the top of the tower body 1, there is another set of alkali solution spraying and packing material, which is not shown in the figure. Finally, it is discharged from the exhaust port at the top of the tower body 1, thereby purifying the waste gas. The purification principle is a known existing technology and will not be described in detail.

[0037] Before purifying the exhaust gas, motor 8 is started to drive the long rod 9 to rotate. The long rod 9 will drive the connected bevel gear 18 to rotate. This bevel gear 18 will drive another bevel gear 18 that meshes with it to rotate. The other bevel gear 18 will drive the circular tube 21 to rotate within the upper plate frame 15. The circular tube 21 will also drive the cylindrical shell 20, rotating column 25, limiting ring 28, two push columns 29, two push tubes 23, and the internal structure connected to the circular tube 21 to rotate together. At the same time, motor 2 34 inside the circular tube 21 is started. Motor 2 34 will drive the connecting rod 41 to rotate. The connecting rod 41 will drive the bevel gear 3 38 to rotate. The bevel gear 3 38 will drive two bevel gears 3 3 8 to rotate. The two bevel gears 3 3 8 will drive their respective connected circular columns 40 to rotate. The two circular columns 40 will drive their respective connected push tubes 23 to rotate. That is to say, the two push tubes 23 will not only rotate around the center of the circular tube 21, but will also rotate on their own axis. The nozzles 19 outside the two push tubes 23 will also rotate in the same way.

[0038] In the above process, water pump 5 is simultaneously activated. Water pump 5 can input the anti-sticking agent inside the storage tank 6 into the round pipe 21 through the water suction pipe 12 and the delivery pipe 11. The anti-sticking agent will also be delivered along the two conduits 35 and the two L-shaped pipes 36 and fill the two push pipes 23 respectively. Under the action of water pressure, the conical block 39 at the end of each spray pipe 19 will be opened. The conical block 39 will drive the connecting column 26 to slide within the splicing block 42 and stretch the spring 22. The anti-sticking agent will be sprayed out in a ring shape along the conical surface of the conical block 39. This can... It effectively expands the spraying range. With the nozzle 19 rotating around the center of the circular tube 21 and rotating on its own axis, and the two push tubes 23 being in the middle position between the upper plate frame 15 and the lower plate frame 14, it can not only continuously flip the packing between the upper plate frame 15 and the lower plate frame 14, but also evenly spray the anti-sticking agent into the packing, so that the anti-sticking agent can fully contact the packing. Then, the water pump 5 is turned off. After the water pressure is lost, the cone block 39 can also self-seal the nozzle 19 under the reaction force of the spring 22, preventing the subsequent exhaust gas from entering the nozzle 19.

[0039] In summary, when the filler with a fully coated anti-sticking agent comes into contact with the acidification waste gas from vegetable oil soap residue, the sticky substances in the waste gas are less likely to form stubborn adhesion on the filler surface (the low surface energy film formed by the anti-sticking agent on the filler surface can significantly reduce the interfacial tension between the sticky substances and the filler), and are easily washed off by the alkaline solution. Furthermore, the agitated filler can further promote the contact effect between the filler and the waste gas and alkaline solution, thereby improving the neutralization reaction efficiency.

[0040] It should be noted that silicone oil can be selected as the anti-sticking agent. Silicone oil has good chemical stability, is not compatible with most organic substances, does not react with alkaline solutions, and an appropriate amount of silicone oil does not affect the properties of the filler. It does not react with acidic gases, nor does it undergo esterification, oxidation, or other reactions with fatty acids, oils, or other organic substances.

[0041] It should also be noted that when the round tube 21 drives the cylindrical shell 20, rotating column 25, limiting ring 28, two push columns 29 and two push tubes 23 to rotate together, the two push columns 29 will rotate to compress their respective hemispherical blocks 27. Under the action of the compressing force, the two hemispherical blocks 27 can be driven to move upward and move the lower plate frame 14 upward a short distance. The lower plate frame 14 will drive multiple guide columns 31 to slide upward in their respective connecting blocks 32 and stretch the spring 30. When the two push columns 29 rotate away from their respective hemispherical blocks 27, under the reaction force of the spring 30, the lower plate frame 14 will move downward and hit the limiting ring 28. As the two push columns 29 continue to rotate, the lower plate frame 14 will vibrate continuously. With the spraying of the anti-sticking agent mentioned above, the lower plate frame 14 will also come into contact with the anti-sticking agent, which can effectively prevent the lower plate frame 14 from clogging, thereby improving the overall purification effect.

[0042] It should also be noted that the anti-sticking agent can be sprayed intermittently, with the anti-sticking agent being sprayed after the filler has been used for a period of time.
