Description

Technical Field

[0001] This utility model belongs to the field of riboflavin fermentation production technology, specifically, it relates to a device for recovering and utilizing oxygen carriers from riboflavin fermentation tail gas. Background Technology

[0002] The riboflavin fermentation process generates a large amount of exhaust gas, which contains components such as oxygen, nitrogen, and carbon dioxide. Among these, oxygen, as an important oxygen carrier, can be effectively recovered and reused, which can not only reduce production costs but also reduce resource waste. At the same time, the rational treatment and utilization of other components in the exhaust gas also meets the current industrial requirements of green environmental protection and sustainable development.

[0003] When replacing the oxygen-enriched membrane in existing recycling devices, the fixed structure and non-adjustable installation port position often limit personnel to operating from a specific angle. This not only greatly increases the difficulty of replacement but also makes operation extremely inconvenient, especially in space-constrained situations. It can even require a significant amount of time to make temporary adjustments to surrounding equipment, severely impacting work efficiency. To address this, we propose a riboflavin fermentation tail gas oxygen carrier recycling device. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 4 As shown, a riboflavin fermentation tail gas oxygen carrier recovery and utilization device includes a separation cylinder 1 and an oxygen-enriching membrane 8. Connecting barrels 2 are connected to both sides of the separation cylinder 1. Each connecting barrel 2 has a gas guide barrel 3 connected to one end, and the gas guide barrel 3 is rotatably connected to the connecting barrel 2. An air inlet pipe 4 is connected to one end of the left connecting barrel 2, and an air outlet pipe 5 is connected to one end of the right connecting barrel 2. An exhaust pipe 6 is connected to the top of the left connecting barrel 2. A back pressure valve 7 is installed on the exhaust pipe 6. The top and bottom of the separation cylinder 1 are provided with mounting grooves 10. The bottom of the inner wall of the mounting groove 10 is provided with an mounting port 19. A fixing frame 9 is inserted into the mounting port 19. The oxygen-enriching membrane 8 is installed on the inner wall of the fixing frame 9. A cover plate 12 is engaged in the mounting groove 10. A limiting component for fixing the cover plate 12 is provided on the outer wall of the separation cylinder 1. A fixing component for fixing the connecting barrel 2 is provided between the gas guide barrel 3 and the connecting barrel 2.

[0018] Furthermore, a T-shaped ring plate 26 is installed at the other end of the air guide barrel 3, and a T-shaped rotating groove is opened at one end of the connecting barrel 2. The T-shaped ring plate 26 is rotatably connected to the T-shaped rotating groove.

[0019] The T-shaped ring plate 26 can be used to limit the connection barrel 2, so that the connection barrel 2 can be fixed and rotated on the air guide barrel 3.

[0020] Furthermore, a sealing ring 28 is installed at the other end of the air guide barrel 3, and the sealing ring 28 is tightly fitted to one end of the connecting barrel 2.

[0021] By setting a sealing ring 28, the sealing performance between the air guide tank 3 and the connecting tank 2 can be increased.

[0022] Furthermore, the limiting component includes a clamping plate 13, a T-shaped connecting shaft 15 is installed at the bottom of the clamping plate 13, a T-shaped connecting groove 14 is opened on the outer wall of the separating cylinder 1, the T-shaped connecting shaft 15 is rotatably connected to the T-shaped connecting groove 14, a torsion spring 16 is connected between the inner wall of the T-shaped connecting groove 14 and the outer wall of the T-shaped connecting shaft 15, and the clamping plate 13 is clamped on the outer wall of the cover plate 12.

[0023] The cover plate 12 can be fixed by setting a locking plate 13 so that it can be snapped onto the outer wall of the cover plate 12.

[0024] Furthermore, a magnetic plate 17 is fixedly embedded at the top of the cover plate 12, and a magnetic block 18 is fixedly embedded at the bottom of the card plate 13. The magnetic block 18 is magnetically connected to the magnetic plate 17.

[0025] By setting up magnetic block 18 and magnetic plate 17, the card plate 13 can be attracted, thereby improving the stability of the card plate 13 engagement.

[0026] Furthermore, the fixing assembly includes a fixing ring plate 20 and a fastening screw 24. The fixing ring plate 20 is fixedly sleeved on the outer wall of the connecting barrel 2. A fixing plate 23 is installed on the outer wall of the air guide barrel 3. The fastening screw 24 is threadedly connected to the threaded hole opened on the fixing plate 23. A fixing ring groove 21 is opened on the outer side of the fixing ring plate 20. One end of the fastening screw 24 is inserted into the fixing ring groove 21.

[0027] The fastening screw 24 can be used to fix the fixing ring plate 20.

[0028] Furthermore, a knob 25 is installed at the other end of the fastening screw 24.

[0029] The knob 25 is designed to facilitate operation by allowing personnel to rotate the fastening screw 24.

[0030] Furthermore, a pad 22 is installed on the inner wall of the fixing ring groove 21, and one end of the fastening screw 24 is tightly fitted with the pad 22. The pad 22 is made of PVC soft rubber.

[0031] By setting the abutment 22, the friction between the fastening screw 24 and the inner wall of the fixing ring groove 21 can be increased.

[0032] The implementation principle of a riboflavin fermentation tail gas oxygen carrier recovery and utilization device is as follows: During use, the dried tail gas enters the left-side gas guide tank 3 through the inlet pipe 4, and then passes through the oxygen-enriched membrane 8, so that the oxygen in the tail gas permeates through the oxygen-enriched membrane 8 faster than the nitrogen. An oxygen-enriched flow is formed on the right permeation side of the membrane, while most of the nitrogen and carbon dioxide are intercepted, and an oxygen-deficient flow is formed on the left interception side of the membrane. The oxygen-enriched flow is discharged through the outlet pipe 5 for recovery, while the oxygen-deficient flow is discharged through the exhaust pipe 6 and the back pressure valve 7 for recovery, which is convenient for subsequent utilization. When the oxygen-enriched membrane 8 needs to be replaced after prolonged use, depending on the installation environment of the device, turn knob 25 to move the fastening screw 24 outward, so that the fastening screw 24 is no longer pressed against the fixing ring groove 21 and no longer fixes the fixing ring plate 20. At this time, rotate the separation cylinder 1 so that one of the two mounting ports 19 on the separation cylinder 1 faces the direction of disassembly. Then rotate the clamping plate 13, so that the clamping plate 13 drives the T-shaped connecting shaft 15 to twist the torsion spring 16, so that the clamping plate 13 is no longer stuck to the outer wall of the cover plate 12. Then remove the cover plate 12, pull the fixing frame 9 outward, and the fixing frame 9 will pull the oxygen-enriched membrane 8 away from the separation cylinder 1. Then replace it with a new oxygen-enriched membrane 8 and replace the cover plate 12 again. When the clamping plate 13 is released, the T-shaped coupling 15 will be driven by the resetting force of the torsion spring 16 to clamp the clamping plate 13 back onto the cover plate 12 for positioning. Then, the fastening screw 24 is tightened, causing the fastening screw 24 to press against the fixing ring groove 21 again, thus fixing the separation cylinder 1 and completing the disassembly and replacement. Through the above structure, two mounting ports 19 are provided on the separation cylinder 1, and when the fixing component is used to release the separation cylinder 1, the separation cylinder 1 can rotate freely, allowing the mounting ports 19 to face any angle. This makes it easy for personnel to disassemble and replace the oxygen-enriched membrane 8 from any angle, making the device adaptable to various installation environments, greatly reducing the difficulty for personnel in disassembling and replacing the oxygen-enriched membrane 8, and improving the work efficiency of personnel.
