[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-4 ,in, Figure 1 A front cross-sectional view of a preferred embodiment of the waste gas treatment equipment for fatty acid oil processing provided by this utility model; Figure 2 for Figure 1 An enlarged structural diagram of part A shown in the figure; Figure 3 for Figure 1 An enlarged structural diagram of part B shown in the figure; Figure 4 This is a schematic diagram of the assembly structure of the inner ring and outer ring in this utility model.

[0018] The waste gas treatment equipment for fatty acid oil processing includes: a tank 1; a liquid nitrogen pipe 3 installed inside the tank 1 via a connecting pipe 2 for storing liquid nitrogen to assist in the cooling and condensation of gaseous substances; an inner ring 4 sleeved on the liquid nitrogen pipe 3 for scraping off viscous residues; an outer ring 5 sleeved on the inner ring 4 and in contact with the inner wall of the tank 1 for scraping off viscous residues; a threaded cylinder 6 fixed on the outer ring 5; and a connection structure detachably installed on the threaded cylinder 6 for providing an operating grip point. By setting up the liquid nitrogen pipe 3, the equipment achieves the effect of using liquid nitrogen to assist in the cooling and condensation of gaseous substances, effectively improving the treatment of organic matter in the waste gas from fatty acid oil processing. The condensation efficiency is improved by setting the inner ring 4, which scrapes away viscous residues outside the liquid nitrogen tube 3, preventing high-boiling-point or easily polymerizable components from adhering and affecting the condensation effect. The outer ring 5, which contacts the inner wall of the tank 1, can scrape away viscous residues from the inner wall of the tank 1, keeping the inner wall of the tank 1 clean and ensuring the stable operation of the waste gas treatment equipment. The threaded cylinder 6 and detachable connection structure make it easy for operators to hold the connection structure and rotate the inner ring 4 and outer ring 5 to clean the residues. The operation is convenient and the detachable design facilitates maintenance and replacement, thus improving the overall operating efficiency and stability of the fatty acid oil processing waste gas treatment equipment.

[0019] The connecting structure includes a threaded rod 7 threaded inside the threaded cylinder 6, a connecting rod 8 fixed to the threaded rod 7, and the connecting rod 8 extending outside the tank body 1. An adjusting block 9 is installed on the connecting rod 8 to provide an operating grip point. By setting the threaded rod 7 threaded inside the threaded cylinder 6, the connecting structure achieves a stable and detachable connection with the outer ring 5, facilitating subsequent maintenance and component replacement. The connecting rod 8, fixed to the threaded rod 7 and extending outside the tank body 1, extends the operating position from inside the tank body 1 to the outside, allowing operators to operate from the outside. The adjusting block 9 installed on the connecting rod 8 provides the operator with a clear operating grip point, enabling easier and safer rotation of the connecting rod 8, which in turn drives the inner ring 4 and outer ring 5 to rotate. This effectively scrapes away viscous residues from the inner wall of the tank body 1 and the outside of the liquid nitrogen pipe 3, improving the convenience and safety of equipment cleaning and ensuring the continuous and efficient operation of the waste gas treatment equipment.

[0020] A fixing bracket 14 is fixed to the top of the tank body 1. A spring 15 is installed on the inner wall of the top of the fixing bracket 14. A blocking plate 16 is installed at the bottom of the spring 15. The top of the tank body 1 has a pressure relief port connected to the connecting pipe 2. The blocking plate 16 is used to close the pressure relief port. A sealing gasket is installed at the bottom of the blocking plate 16. By setting the fixing bracket 14, a stable installation position is provided for the spring 15 and the blocking plate 16, ensuring the stability of the overall structure. The spring 15 provides elastic support for the blocking plate 16, making the blocking plate 16 more stable. Plate 16 can move flexibly within a certain pressure range. By setting plate 16 to seal the pressure relief port at the top of tank 1, it can effectively prevent exhaust gas leakage and ensure the sealing of the equipment under normal working conditions. By setting a sealing gasket at the bottom of plate 16, the sealing effect of the pressure relief port is further enhanced. When the pressure inside the tank rises abnormally, spring 15 is compressed and plate 16 moves upward to open the pressure relief port to release pressure. This design enables the equipment to have an automatic pressure relief function, effectively avoiding safety accidents caused by excessive pressure and improving the safety and reliability of equipment operation.

[0021] Both sides of the tank body 1 are threaded with plugs 10 for auxiliary support of the outer ring 5 via threaded rings 11. Each plug 10 has a handle 12 fixed to it, providing a gripping point. The handle 12 has a sealing ring 13 that contacts the outer wall of the tank body 1 to prevent air leakage. By setting the plugs 10 threaded with the threaded rings 11, the outer ring 5 is effectively supported, ensuring its stability during rotation and cleaning, reducing shaking, and improving cleaning efficiency. The handles 12 fixed to the plugs 10 provide a gripping point, facilitating the installation or removal of the plugs 10 by the operator, and also allowing for rotation to adjust their position. The sealing ring 13 on the handle 12, contacting the outer wall of the tank body 1, ensures a tighter connection between the plugs 10 and the tank body 1, effectively preventing exhaust gas leakage and guaranteeing the sealing and safety of the equipment operation.

[0022] The spring 15 is provided with a limiting telescopic rod for limiting the extension and retraction path of the spring 15. The top of the blocking plate 16 is equipped with a guide rod 17 that movably passes through the fixing frame 14. The top of the tank body 1 is provided with an opening for providing an installation channel for the connecting rod 8. A sealing block is detachably installed in the opening. By setting a limiting telescopic rod in the spring 15, the extension and retraction path of the spring 15 is limited, preventing the spring 15 from shifting or twisting during the extension and retraction process, thus ensuring the stability and reliability of the spring 15. By setting the guide rod 17 that movably passes through the fixing frame 14 at the top of the blocking plate 16, the blocking plate 16 is guided to move stably, so that the blocking plate 16 can maintain vertical movement when opening or closing the pressure relief port, improving the accuracy of the pressure relief operation. The opening at the top of the tank body 1 provides an installation channel for the connecting rod 8, and the sealing block is detachably installed in the opening, so that the connecting rod 8 can be installed smoothly and the sealing of the tank body 1 can be guaranteed when not being cleaned.

[0023] An air inlet pipe is provided on one side of the tank body 1, and a discharge cylinder 18 is installed at the bottom of the tank body 1. A limit frame 19 is installed at the bottom of the discharge cylinder 18, and a collection box 21 for collecting viscous waste is detachably installed inside the limit frame 19. By setting the air inlet pipe on one side of the tank body 1, the waste gas from fatty acid oil processing is introduced into the tank body 1 for treatment, ensuring the smooth progress of the waste gas treatment process. The discharge cylinder 18 installed at the bottom of the tank body 1 serves to discharge the condensed waste, making it convenient to discharge the viscous waste generated during the processing into the tank body 1 in a timely manner. The limit frame 19 is set at the bottom of the discharge cylinder 18, and the collection box 21 is detachably installed, so that the collection box 21 can be placed stably and is easy to disassemble, facilitating the centralized collection of the discharged viscous waste.

[0024] The collection box 21 is equipped with a baffle to seal the limiting frame 19 to prevent air leakage. The limiting frame 19 is equipped with an exhaust pipe 20 for discharging waste gas for subsequent treatment. A connecting rod 8 is installed between the inner ring 4 and the outer ring 5. By installing a baffle on the collection box 21 to seal the limiting frame 19 to prevent air leakage, the sealing effect of the equipment is enhanced, effectively preventing waste gas from leaking from the connection between the limiting frame 19 and the collection box 21, ensuring the environmental protection and safety of the waste gas treatment process. The exhaust pipe 20 installed on the limiting frame 19 serves to discharge waste gas for subsequent treatment, allowing the treated waste gas to be discharged in an orderly manner, facilitating subsequent centralized treatment or emission to meet standards. The connecting rod 8 installed between the inner ring 4 and the outer ring 5 serves to firmly connect the two and rotate synchronously, ensuring that the inner ring 4 and the outer ring 5 can work together when cleaning viscous residues, improving cleaning efficiency and effectiveness.

[0025] The working principle of the waste gas treatment equipment for fatty acid oil processing provided by this utility model is as follows: During use, fatty acid oil processing waste gas enters the tank 1 through the inlet pipe. Liquid nitrogen stored in the liquid nitrogen pipe 3 assists in cooling and condensing the waste gas, causing the organic matter in the waste gas to condense. Under normal operating conditions, spring 15 elastically supports the plug plate 16, which, together with the sealing gasket, seals the pressure relief port at the top of the tank 1 to prevent waste gas leakage. When the pressure inside the tank abnormally increases, spring 15 is compressed, and the plug plate 16 moves upward to open the pressure relief port for pressure release. The viscous waste generated during the process is discharged into the collection box 21 through the discharge cylinder 18. The baffle on the collection box 21 seals the limiting frame 19 to prevent air leakage. The treated waste gas is output through the exhaust pipe 20 for further processing. To clean the viscous residue on the outside of the liquid nitrogen tube 3 and the inside of the tank 1, screw the plug 10 to support the outer ring 5. The operator holds the connecting rod 8 through the adjusting block 9, which drives the threaded rod 7 to rotate inside the threaded cylinder 6, connecting the outer ring 5 and the connecting rod 8. At this time, first remove the plug 10 and then push the connecting rod 8, which will cause the inner ring 4 and the outer ring 5 to move. The inner ring 4 scrapes off the viscous residue on the outside of the liquid nitrogen tube 3, and the outer ring 5 scrapes off the viscous residue on the inside of the tank 1. After cleaning, remove the connecting rod 8 from the opening at the top of the tank 1 and install the sealing block to ensure the sealing of the tank 1. At the same time, the collection box 21 can be removed from the limit frame 19 to process the collected viscous waste.

[0026] Compared with related technologies, the waste gas treatment equipment for fatty acid oil processing provided by this utility model has the following beneficial effects: This utility model provides a waste gas treatment device for fatty acid oil processing. By setting up a liquid nitrogen pipe 3, liquid nitrogen is used to assist in cooling and condensing the gaseous substance, which can effectively improve the condensation efficiency of organic matter in the waste gas of fatty acid oil processing. By setting an inner ring 4 to scrape off viscous residues outside the liquid nitrogen pipe 3 and an outer ring 5 to scrape off viscous residues on the inner wall of the tank 1, it is possible to prevent the residues from accumulating too thickly and affecting the condensation effect. Furthermore, through the threaded cylinder 6 and the detachable connection structure, it is convenient for operators to operate from the outside to slide the inner ring 4 and the outer ring 5 to clean the residues.
