Therefore, the tail gas needs to be recovered and treated. Generally, the recoverable substances are separated from the tail gas through forms such as condensation and liquefaction for recovery. The tail gas first enters the condenser. In the condenser, through the flow of the condensation medium (usually water or other coolants), substances such as ethanol and organic matters in the tail gas are condensed into liquid state. The condensed liquid then enters the separator for physical or chemical separation to obtain valuable chemical substances or for harmless treatment. However, the device still has the following defects: when the above-mentioned equipment is in use, in the process of tail gas treatment by the existing condensation recovery device, some chemical reactions may occur, such as polymerization reaction, to generate incomplete products such as polymers.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A tail gas condensation recovery device for ethanol preparation, comprising: a recycling device body 1. In this design, the model of the recycling device body 1 is: FLK-CWR-10. In this technical solution, the recycling device body 1 is provided with a condenser at its top and a separation mechanism at its bottom. This mechanism is a conventional technology in this field and has no relevance to the technical problems in this technical solution. Therefore, no excessive description is made in this technical solution. In specific use, the tail gas enters the condenser at the top of the recycling device body 1 and exchanges heat with a cooling medium (such as water or other low-temperature fluids). Since the temperature of the cooling medium is lower than the boiling point of ethanol, the ethanol in the tail gas will condense into a liquid state, and then the liquid ethanol is separated from other components in the tail gas through the separator 8. The separated liquid ethanol can be recycled and reused, such as being reintroduced into the production process.

[0021] At the front end of the main body 1 of the recycling device, there is a discharge port 2. A first sleeve 3 is sleeved on the surface of the discharge port 2. The inner wall of the other side of the first sleeve 3 is threadedly connected to a threaded pipe 4. A connecting pipe 5 is sleeved on the inner wall of the threaded pipe 4. The lower end of the connecting pipe 5 is sleeved with a second sleeve 6. The bottom of the second sleeve 6 is threadedly connected to a limiting pipe 7. The inner wall of the limiting pipe 7 abuts against the connecting pipe 5. The bottom of the limiting pipe 7 is connected to a separator 8. The bottom of the separator 8 is connected to the surface of the main body 1 of the recycling device.

[0022] Preferably: The end of the first sleeve 3 near the discharge port 2 is made of rubber material. The inner wall of the first sleeve 3 is provided with a threaded structure whose shape and size match those of the threaded pipe 4.

[0023] During specific use, the first sleeve 3 threadedly connected to the threaded pipe 4 sleeved on the upper surface of the connecting pipe 5 is rotated downward together, so as to disengage from the sleeved discharge port 2, enabling the connecting pipe 5 to be disassembled and replaced.

[0024] Preferably: Eight through grooves are annularly formed on the surface of the limiting pipe 7. Semi-circular convex blocks are provided on both sides of the lower end of the connecting pipe 5 and abut against the upper groove of the second sleeve 6. A threaded groove is formed on the inner wall of the second sleeve 6 whose shape and size match those of the threaded groove on the surface of the limiting pipe 7.

[0025] During specific use, the second sleeve 6 threadedly fixed on the limiting pipe 7 is rotated upward, so that the bottom of the connecting pipe 5 abutting against the inner wall of the limiting pipe 7 can be pulled out from the top of the separator 8.

[0026] Preferably: A support plate 9 is connected to the bottom of the condenser at the top of the main body 1 of the recycling device. A screw rod 10 is threadedly connected to one side of the support plate 9. The side wall of the screw rod 10 penetrates and connects to a support rod 11. The two sides of the top surface of the support rod 11 are fitted and connected to the connecting ears on the side wall of the support plate 9. The bottom of the support rod 11 is rotatably connected to a base 13 by a rotating shaft 12. The bottom surface of the base 13 is threadedly connected to a bottom plate 14. The front end of the bottom plate 14 is slidably connected to the bottom support frame of the main body 1 of the recycling device. A fixing bolt 15 is threadedly connected at the intersection of the bottom support frame of the main body 1 of the recycling device and the plate 14.

[0027] During specific use, the base 13 is threadedly fixed in the threaded groove formed on one side of the top of the bottom plate 14, thereby fixing the position of the support rod 11. At the same time, the rotating shaft 12 connected to the bottom of the support rod 11 enables it to rotate and adjust the angle on the top of the bottom plate 14, so as to be fitted into the groove on one side of the support plate 9 and support and fix the main body 1 of the recycling device.

[0028] Preferably: The support plate 9, the screw rod 10 and the support rod 11 form a threaded connection structure.

[0029] During specific use, the screw rod 10 fixed between the support plate 9 and the support rod 11 is screwed out, so as to facilitate the separation of the support plate 9 and the support rod 11 and the disassembly of the support rod 11.

[0030] Preferably, a chute is formed at the bottom of the main body 1 of the recycling device, and its shape and size are in line with those of the bottom plate 14. Two threaded through-holes are formed at the transverse ends of the bottom plate 14, and their shape and size are in line with those of the fixing bolts 15.

[0031] During specific use, the fixing bolts 15 penetrate through the main body 1 of the recycling device and are fixed in the corresponding grooves formed at the top of the bottom plate 14, thereby fixing the position of the bottom plate 14. Then, the base 13 is threadedly fixed in the threaded groove formed at one side of the top of the bottom plate 14, thereby fixing the position of the support rod 11.

[0032] Working principle: When the main body 1 of the recycling device processes the tail gas for ethanol production, the fixing bolts 15 fixed between the base 13 and the bottom plate 14 are unscrewed, and then the bottom plate 14 is pulled outwards so that it slides outwards at the bottom of the main body 1 of the recycling device to the corresponding position. After that, the fixing bolts 15 penetrate through the main body 1 of the recycling device and are fixed in the corresponding grooves formed at the top of the bottom plate 14, thereby fixing the position of the bottom plate 14. Then, the base 13 is threadedly fixed in the threaded groove formed at one side of the top of the bottom plate 14, thereby fixing the position of the support rod 11. At the same time, the rotating shaft 12 connected to the bottom of the support rod 11 enables it to rotate and adjust the angle at the top of the bottom plate 14, so as to be fitted into the groove on one side of the support plate 9. The connection between the support plate 9 and the support rod 11 is fixed by screwing the screw rod 10 through the side wall of the support plate 9 and the threaded groove at the top of the support rod 11. The position of the main body 1 of the recycling device is supported by the support rod 11 and the bottom plate 14, increasing the contact area between the ground and the main body 1 of the recycling device and making it more stably fixed in place. Then, the condenser at the top of the main body 1 of the recycling device condenses the tail gas generated during ethanol processing, and then it is transmitted to the separator 8 through the connecting pipe 5 and finally discharged through the exhaust port. After the processing is completed, the second sleeve 6 threadedly fixed on the limiting pipe 7 can be rotated upwards, so that the bottom of the connecting pipe 5 abutting against the inner wall of the limiting pipe 7 can be pulled out from the top of the separator 8. At the same time, the first sleeve 3 threadedly connected to the threaded pipe 4 sleeved on the upper surface of the upper end of the connecting pipe 5 is rotated downwards together, so as to be disengaged from the sleeved discharge port 2, enabling the connecting pipe 5 to be disassembled and replaced to avoid the accumulation of dirt inside it during long-term use, which affects the normal operation of the main body 1 of the recycling device.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
