Description

Technical Field

[0001] The present invention relates to the technical field of alcohol rectification equipment, and specifically relates to a continuous alcohol rectification device. Background Art

[0002] To improve the purity of alcohol, it is often necessary to carry out rectification and purification processing on alcohol, and thus alcohol rectification equipment is required. The invention patent with the patent application number CN201310268358.8 discloses a general distillation unit for edible alcohol and fuel alcohol, which transplants the azeotropic distillation method for producing anhydrous alcohol into the fuel alcohol system, replaces the molecular sieve system, adopts a unique design for the structure and process flow of the tower, and forms a brand-new distillation unit, which consists of a mash column, a rectification column, a dehydration / methanol column and a recovery / impurity column; the four distillation columns are all multi-functional columns, and using the same system, edible alcohol or fuel alcohol can be produced, achieving multi-purpose use of one machine, simplifying the production process, having less equipment investment, low energy consumption, strong product adaptability, and simple operation. The invention patent with the patent application number CN202010315835.1 discloses a multi-column differential pressure energy-saving anhydrous alcohol distillation system and an anhydrous alcohol energy-saving production method, which continuously uses heat-conducting oil to provide heat sources for the rectification column heater, alcohol evaporation heater and superheater, can accelerate the heat conduction speed and provide stable heat supply, has low energy consumption and high safety in producing anhydrous alcohol, and avoids the problems caused by using steam as a heat source. The high-temperature alcohol gas generated by the rectification column, water washing column and methanol column is recycled as a heat source. Since the rectification column uses heat-conducting oil for heating, it can generate high-temperature and stable alcohol gas, which can ensure the heat demand of the water washing column heater and methanol column heater. The alcohol gas generated by the water washing column and methanol column is respectively used to supply the first reboiler and the second reboiler of the rough distillation column, ensuring the heat energy supply for the rough distillation of the rough distillation column and improving the rough distillation efficiency. A flash tank is set to utilize the waste liquid to generate secondary steam for use by the recovery column heater. When the temperature of the recovery column does not reach the requirement, it is assisted by the recovery column heater for heating, and the flow rate of the heat-conducting oil is controlled to ensure that the recovery column can always maintain an appropriate working temperature during the production process. According to the disclosed technical solutions, when the existing alcohol rectification equipment is in use, on the one hand, during the rectification operation of alcohol, a certain amount of low-concentration alcohol aqueous solution will be generated in each distillation operation, which is not conducive to improving the purification rate of alcohol; on the other hand, when performing multiple rectification operations on alcohol, it is often necessary to consume a large amount of energy to heat the original liquid to a high temperature state, increasing the energy consumption; on the other hand, during the distillation process, the concentration will decrease with the evaporation of alcohol, which will cause more water to be carried away in the subsequent evaporation operation, and thus it is easy to cause the alcohol concentration to decrease due to more water in the rectification operation, which is not conducive to ensuring the purity of alcohol.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the continuous alcohol rectification device is in use, the alcohol solution enters the thin box through the inlet pipe and flows back and forth up and down through the elbow in the thin box to fully absorb the heat in the side box. The water pump 1 pumps the alcohol solution to the bottom of the auxiliary box, and it flows back and forth inside the cold cavity under the limit of the baffle, while absorbing the heat of the cold pipe. The alcohol solution flows upward through the outer pipe, absorbs heat in the cold cavity, then enters the top of the main box through the connecting pipe. The electric heating plate heats the alcohol solution to evaporate and separate the alcohol. The alcohol vapor enters the auxiliary box through the gas pipe and is absorbed and liquefied by the alcohol solution in the cold cavity, then falls to the inside of the hot cavity, and is heated and evaporated again by the electric heating plate in the hot cavity. The alcohol vapor flows downward through the cold pipe, liquefies in the cold pipe and then falls into the hot cavity again, and is heated and evaporated again until the purified alcohol vapor is cooled and liquefied in the cold pipe and flows out through the outlet. After each purification, due to the reduction of water, the concentration of the remaining solution in the hot cavity increases. At the same time, the floating block in the side sleeve presses the button to control the water pump 2 and the water pump 2 to transport the remaining solution to the previous link, so that the separated solution can be concentrated and purified in time, reducing the generation of residual liquid during the alcohol purification work and improving the purification rate of alcohol.

[0015] 2. When the continuous alcohol rectification device is in use, water enters the inside of the side box and flows back and forth up and down inside the side box along the gap between the thin box and the elbow, so that the heat of the water is fully absorbed by the thin box. When the solution flows in the thin box and the cold cavity, it can effectively absorb the heat of the hot water in the side box and the alcohol vapor in the cold pipe, reducing the energy consumption when heating the solution to the evaporation state and improving the energy conservation and emission reduction effect of the equipment.

[0016] 3. When the continuous alcohol rectification device is in use, after the alcohol in the solution at the top of the main box evaporates, the solution with reduced concentration enters the inside of the through pipe through the inner pipe. The floating plate ensures that the inner pipe can move up and down with the liquid level, thereby ensuring that the solution can flow stably downward, avoiding affecting the separation efficiency of alcohol due to flow rate fluctuations. The solution in the through pipe pushes open the pressure valve and flows downward to the partition at the adjacent bottom. As the concentration of alcohol decreases, its evaporation temperature increases. Under the heating of the electric heating plate, the alcohol vapor carries water vapor and flows upward through the elbow pipe. Due to the lower temperature at the top, the water vapor and part of the alcohol vapor liquefy and are separated together with the distillation work. When the liquid flows downward, the concentration of alcohol gradually decreases, reducing the alcohol residue and improving the separation rate of alcohol. When the gas flows upward, it continuously liquefies the water and returns it to the liquid, thereby effectively ensuring that the alcohol concentration of the steam entering the auxiliary box is fully increased, reducing the water content in the steam, and thus improving the purity of the finally purified alcohol.

The two ends of the bent pipe 21 are respectively welded to the bottoms of two adjacent partitions 14. An air pipe 22 is welded to the top of the main box 1. One end of the air pipe 22 passes through the cold chamber 8 at the top of the sub-box 2 and is connected to the adjacent hot chamber 9. A cold pipe 24 is welded inside the hot chamber 9. The top end of the cold pipe 24 is located at the top inside the hot chamber 9. The bottom end of the cold pipe 24 passes through the bottom of the hot chamber 9, coils inside the cold chamber 8, then passes through the bottom of the cold chamber 8 and is connected to the top of the hot chamber 9. An outlet 25 is welded to the bottom of the sub-box 2, and the outlet 25 is connected to the bottom end of the cold pipe 24. When in use, water enters the inside of the side box 3 and flows back and forth inside the side box 3 along the gap between the thin box 5 and the elbow 6, so that the heat of the water is fully absorbed by the thin box 5. When the solution flows inside the thin box 5 and the cold chamber 8, it can effectively absorb the heat of the hot water in the side box 3 and the alcohol vapor in the cold pipe 24, reduce the energy consumption when heating the solution to the evaporation state, and improve the energy conservation and emission reduction effect of the equipment.

[0020] In this embodiment, the cold chambers 8 and the hot chambers 9 are alternately distributed inside the secondary tank 2, and the secondary tank 2 is installed on the other side of the main tank 1. One side of the first water pump 7 passes through the outer side of the side tank 3 and is connected to the thin tank 5. The other side of the first water pump 7 passes through the outer side of the secondary tank 2 and is connected to the cold chamber 8 at the bottom of the secondary tank 2. A baffle 10 is welded inside the cold chamber 8, and the baffles 10 are alternately distributed on both sides of the cold chamber 8. An outer pipe 11 is welded to the outer side of the secondary tank 2, and the adjacent cold chambers 8 are connected through the outer pipe 11. A connecting pipe 12 is welded to the secondary tank 2, and the cold chamber 8 at the top of the secondary tank 2 is connected to the top of the main tank 1 through the connecting pipe 12. The partition 14 is welded inside the main tank 1, and the partitions 14 are evenly distributed inside the main tank 1. The electric heating plates 15 are respectively welded to the bottom of the hot chamber 9 and the top of the partition 14. The guide plate 13 is welded to the top of the partition 14, and the guide plates 13 are alternately distributed on the inner walls on both sides of the main tank 1. The top end of the through pipe 16 is located at the top of the partition 14, and the bottom end of the through pipe 16 passes through the partition 14 and extends to the top of the adjacent bottom partition 14. The inner pipe 17 is stuck inside the through pipe 16, and the top end of the inner pipe 17 extends to the top of the through pipe 16. A floating plate 18 is welded to the top end of the inner pipe 17. The pressure valve 19 is installed on the outer side of the main tank 1 by bolts. One end of the pressure valve 19 passes through the outer side of the main tank 1 and extends to the inside of the through pipe 16. The bottom of the main tank 1 is connected to the side tank 3, and a drain port 20 is welded to one side of the side tank 3. When in use, after the solution at the top of the main tank 1 evaporates alcohol, the solution with reduced concentration enters the inside of the through pipe 16 through the inner pipe 17. The floating plate 18 ensures that the inner pipe 17 can move up and down with the liquid level, thereby ensuring that the solution can flow downward stably and avoiding affecting the separation efficiency of alcohol due to flow rate fluctuations. The solution in the through pipe 16 flows downward to the partition 14 at the adjacent bottom by pushing open the pressure valve 19. As the concentration of alcohol decreases, its evaporation temperature increases. Under the heating of the electric heating plate 15, the alcohol vapor carries water vapor and flows upward through the elbow pipe 21. Since the temperature at the top is relatively low, the water vapor and a part of the alcohol vapor are liquefied and undergo distillation separation work together. When the liquid flows downward, the concentration of alcohol gradually decreases, reducing the alcohol residue and improving the separation rate of alcohol. When the gas flows upward, the water is continuously liquefied and returns to the liquid, thereby effectively ensuring that the alcohol concentration of the vapor entering the secondary tank 2 is fully increased, reducing the water content in the vapor, and thus improving the purity of the finally purified alcohol.

[0021] In this embodiment, a dividing plate 23 is welded to the inner wall of the hot chamber 9. The dividing plate 23 is alternately welded to the inner walls of the top and bottom of the hot chamber 9. The second water pump 26 is installed on the outer side of the auxiliary tank 2 by bolts. The bottom of the hot chamber 9 is connected to the top of the adjacent hot chamber 9 through the second water pump 26. The third water pump 27 is installed on the outside of the auxiliary tank 2 by bolts. The hot chamber 9 is connected to the top of the main tank 1 through the third water pump 27. A side sleeve 28 is welded to the outer side of the auxiliary tank 2. The side sleeve 28 is connected to the bottom of the hot chamber 9. A floating block 29 is clamped inside the side sleeve 28. A button 30 is welded to the inner wall of the side sleeve 28. The button 30 is located on the top of the floating block 29. A control component is externally connected to the main tank 1. The control component is connected to the first water pump 7 and the button 30 through wires. The button 30 is connected to the second water pump 26 and the third water pump 27 through wires. During use, the alcohol solution enters the thin tank 5 through the inlet pipe 4 and flows back and forth up and down in the thin tank 5 through the elbow 6 to fully absorb the heat in the side tank 3. The first water pump 7 pumps the alcohol solution to the bottom of the auxiliary tank 2 and flows back and forth inside the cold chamber 8 under the limitation of the baffle 10, while absorbing the heat of the cold pipe 24. The alcohol solution flows upward through the outer pipe 11 and absorbs heat in the cold chamber 8, and then enters the top of the main tank 1 through the connecting pipe 12. The electric heating plate 15 heats the alcohol solution to cause alcohol evaporation and separation. The alcohol vapor enters the auxiliary tank 2 through the air pipe 22 and is absorbed by the alcohol solution and liquefied in the cold chamber 8, then falls to the inside of the hot chamber 9, and is heated and evaporated again by the electric heating plate 15 in the hot chamber 9. The alcohol vapor flows downward through the cold pipe 24, liquefies in the cold pipe 24 and then falls to the inside of the hot chamber 9 again, and is heated and evaporated again until the purified alcohol vapor is cooled and liquefied in the cold pipe 24 and flows out through the outlet 25. After each purification, due to the reduction of water, the concentration of the remaining solution in the hot chamber 9 increases. At the same time, the floating block 29 in the side sleeve 28 presses the button 30 to control the second water pump 26 and the third water pump 27 to transport the remaining solution to the previous link, so that the separated solution can be concentrated and purified in time, reducing the generation of residual liquid during the alcohol purification work and improving the purification rate of alcohol.

[0022] This continuous alcohol rectification device provides electrical energy for all electrical equipment through an external power supply. During use, the alcohol solution enters the thin box 5 through the inlet pipe 4 and flows back and forth up and down through the elbow 6 in the thin box 5 to fully absorb the heat in the side box 3. The first water pump 7 pumps the alcohol solution to the bottom of the auxiliary box 2 and flows back and forth inside the cold cavity 8 under the limitation of the baffle 10 while absorbing the heat of the cold pipe 24. The alcohol solution flows upward through the outer pipe 11, absorbs heat in the cold cavity 8, and then enters the top of the main box 1 through the connecting pipe 12. The electric heating plate 15 heats the alcohol solution, causing the alcohol to evaporate and separate. The alcohol vapor enters the auxiliary box 2 through the gas pipe 22 and is absorbed and liquefied by the alcohol solution in the cold cavity 8, then falls to the inside of the hot cavity 9 and is heated and evaporated again by the electric heating plate 15 in the hot cavity 9. The alcohol vapor flows downward through the cold pipe 24, liquefies in the cold pipe 24 and then falls into the hot cavity 9 again, and is heated and evaporated again until the purified alcohol vapor is cooled and liquefied in the cold pipe 24 and flows out through the outlet 25. After each purification, due to the reduction of water, the concentration of the remaining solution in the hot cavity 9 increases. At the same time, the floating block 29 in the side sleeve 28 presses the button 30 to control the second water pump 26 and the third water pump 27 to transport the remaining solution to the previous link, so that the separated solution can be concentrated and purified in time, reducing the generation of residual liquid during alcohol purification work and improving the purification rate of alcohol. After the alcohol in the solution at the top of the main box 1 evaporates, the solution with a reduced concentration enters the inside of the through pipe 16 through the inner pipe 17. The floating plate 18 ensures that the inner pipe 17 can move up and down with the liquid level, thereby ensuring that the solution can flow stably downward and avoiding affecting the separation efficiency of alcohol due to flow rate fluctuations. The solution in the through pipe 16 flows downward to the partition 14 at the adjacent bottom by pushing open the pressure valve 19 under pressure. As the concentration of alcohol decreases, its evaporation temperature increases. Under the heating of the electric heating plate 15, the alcohol vapor carries water vapor and flows upward through the elbow 21. Due to the lower temperature at the top, the water vapor and a part of the alcohol vapor liquefy and are separated by distillation together. When the liquid flows downward, the concentration of alcohol gradually decreases, reducing the alcohol residue and improving the separation rate of alcohol. When the gas flows upward, the water is continuously liquefied and returns to the liquid, thereby effectively ensuring that the alcohol concentration of the vapor entering the auxiliary box 2 is fully increased, reducing the water content in the vapor, and thus improving the purity of the finally purified alcohol. The water enters the inside of the side box 3 and flows back and forth up and down inside the side box 3 along the gap between the thin box 5 and the elbow 6, so that the heat of the water in the side box 3 is fully absorbed by the thin box 5. When the solution flows in the thin box 5 and the cold cavity 8, it can effectively absorb the heat of the hot water in the side box 3 and the alcohol vapor in the cold pipe 24, reducing the energy consumption when heating the solution to the evaporation state and improving the energy conservation and emission reduction effect of the equipment.
