Description

Technical Field

[0001] The present invention relates to the field of liquor processing, and more particularly to a high-efficiency condensation recovery device for liquor distillation steam. Background Art

[0002] Baijiu, a traditional Chinese distilled liquor with a long history and rich cultural connotations, is a key step in its production, separating and purifying the alcohol from the other components of the fermentation broth. This process typically involves heating the fermentation broth to evaporate the alcohol into vapor, which is then cooled and converted to a liquid form for collection in a condenser.

[0003] Condensation recovery in the liquor production process is a sealed process used to guide high-temperature alcohol vapor from the distillation tower to the condenser. Traditionally, these vapors rely on natural flow or slight pressure differences to move to the condenser. However, during this process, due to uneven steam flow speed and insufficient contact time with the condensing surface, some alcohol vapor is discharged from the system before it is fully liquefied, resulting in significant production losses and waste of resources. In addition, increasing the flow rate or lowering the temperature of the cooling medium to improve condensation efficiency often leads to a significant increase in energy consumption, increasing production costs. Summary of the Invention

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a high-efficiency condensation and recovery device for liquor distillation steam, which can absorb the alcohol vapor that has not been condensed and liquefied, and blow it back to the condenser to achieve contact, so as to maximize the recovery of the alcohol component in the alcohol vapor, reduce the product loss caused by incomplete condensation, and improve the overall condensation efficiency and resource utilization.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0011] Furthermore, magnet blocks are fixedly mounted on the top of each group of the sliding rods and the bottom of the cross plate, and two adjacent groups of magnet blocks are mounted by magnetic attraction.

[0012] Furthermore, a conical cover is provided on the lower side of each group of blowing holes, and each group of the conical cover is fixedly installed on the bottom of the mounting frame. A guide rod is provided inside each group of the conical cover, and the top end of each group of the guide rod is fixedly installed on the top wall of the inner cavity of the air storage cavity, and the bottom end of each group of the guide rod is contacted with the top of the condenser.

[0013] Furthermore, a funnel is provided on the lower side of the condensing tube, and the funnel is fixedly mounted on the inner cavity wall of the recovery box.

[0014] Furthermore, a vertical pipe is fixedly installed on the bottom end of the funnel, and a drainage pipe is fixedly installed on one side of the bottom of the recovery box.

[0015] Furthermore, each group of the reset springs is in a compressed state in its initial state, and the magnetic attraction force of two adjacent groups of the magnet blocks is greater than the elastic force of the reset springs.

[0016] Furthermore, each group of the sliding rods and each group of the magnet blocks in the horizontal direction are arranged in a circular array.

[0017] Furthermore, the annular frame and the protective frame are both made of heat-insulating materials.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution uses a suction fan to reciprocately absorb the alcohol vapor that has not been condensed and liquefied on the lower side of the condenser tube, and eventually it will be discharged downward through the blowing hole and blown directly onto the outer wall of the condenser tube. The uncondensed alcohol vapor can be brought back into contact with the condenser tube through the action of the suction fan, which helps to ensure that more alcohol vapor can be fully condensed, maximize the recovery of the alcohol content in the alcohol vapor, reduce product losses caused by incomplete condensation, improve the overall condensation efficiency and resource utilization, and can achieve a higher condensation rate without significantly increasing energy consumption, thus having an energy-saving effect.

[0020] (2) In this solution, the output shaft of the motor drives the cross plate to rotate slowly. The rotation of the cross plate can disperse the alcohol vapor discharged downward from each group of ports, and the alcohol vapor will diffuse downward and be evenly distributed on the surface of the condenser. This uniform distribution can increase the chance and area of ​​contact between the alcohol vapor and the condenser, thereby accelerating the condensation speed, improving the condensation efficiency, avoiding local overheating in some areas due to excessive concentration of alcohol vapor, and ensuring the balance of the condensation operation.

[0021] (3) In the process of recovering the alcohol vapor that has not been condensed and liquefied, when the alcohol vapor is blown toward the outer wall of the condenser through the air hole, the alcohol vapor will blow toward the alcohol droplets on the outer wall of the condenser, which can increase the kinetic energy of the droplets and make it easier for them to slide down along the wall of the condenser. This helps to prevent the droplets from accumulating to form larger water droplets and reduce the thickness of the liquid film, thereby improving the heat exchange effect and further increasing the space and efficiency of subsequent steam condensation.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 5 , a white wine distillation steam efficient condensation recovery device, comprising a recovery box 1, a ring frame 2 is fixedly installed on the top of the recovery box 1, and a connecting pipe 3 is fixedly installed on one side of the ring frame 2;

[0031] Also includes:

[0032] Diffusion component, the diffusion component includes a protective frame 13 fixedly installed in the annular frame 2, a motor 14 is arranged in the protective frame 13, the motor 14 is fixedly installed with the recovery box 1, the output shaft of the motor 14 is fixedly installed with a cross plate 15, the cross plate 15 is arranged on the upper side of the inner cavity of the recovery box 1, and the bottom of the annular frame 2 and the top of the recovery box 1 are evenly provided with through openings 4, the inner cavity of the recovery box 1 is fixedly installed with a condenser 5, one end of the condenser 5 is fixedly installed with a water inlet end 11, and the other end of the condenser 5 is fixedly installed with a drainage end 12, and a circulation component is provided on the upper side of the condenser 5.

[0033] The circulation component includes an installation frame 8 arranged on the upper side of the condenser 5, an air storage cavity 16 is opened in the installation frame 8, a cavity 9 is opened in the top of the recovery box 1, one end of the installation frame 8 is fixedly installed on the inner cavity top wall of the recovery box 1, and is connected to the inner cavity of the cavity 9, and the other end of the installation frame 8 is sealed. A circulation pipe 6 is fixedly installed on one side of the inner cavity wall of the recovery box 1, and a suction fan 7 is fixedly installed in the inner cavity of the circulation pipe 6. The top of the suction fan 7 is fixedly installed on the inner cavity top wall of the recovery box 1 and is connected to the cavity 9. Blowing holes 10 are evenly opened at the bottom of the installation frame 8.

[0034] First, connect the connecting pipe 3 to the end of the liquor distillation tower that discharges alcohol vapor, then connect the output end of external cold water to the water inlet end 11, and connect the pipe for recovering hot water after heat exchange to the drainage end 12. The cold water will enter the condenser 5 through the water inlet end 11 and flow in the condenser 5, which can reduce the temperature of the condenser 5 in the recovery box 1, so that it forms a low-temperature state. The alcohol vapor will be discharged into the annular frame 2 through the connecting pipe 3, and the alcohol vapor in the annular frame 2 will flow downward through each group of ports 4. Turn on the motor 14, and the output shaft of the motor 14 will drive the cross plate 15 to rotate slowly. The rotation of the cross plate 15 can realize the The alcohol vapor discharged downward is broken up and diffused downward and evenly distributed on the surface of the condenser tube 5. This even distribution can increase the chance and area of ​​contact between the alcohol vapor and the condenser tube 5, thereby accelerating the condensation speed and improving the condensation efficiency. It avoids the situation where some areas are overheated due to excessive concentration of alcohol vapor, and ensures the balance of the condensation operation. After the alcohol vapor passes through the condenser tube 5 for heat exchange, it forms liquid alcohol droplets on the surface of the condenser tube 5. The alcohol droplets gradually slide down on the outer wall of the condenser tube 5 for collection. After the heat exchange, the cold water in the condenser tube 5 becomes hot, and the water in the condenser tube 5 after heat exchange is discharged and recycled through the drainage end 12.

[0035] Turn on the suction fan 7. When the suction fan 7 works, it will absorb the gas on the lower side of the condenser 5 through the circulation pipe 6 and then discharge it upward through the circulation pipe 6. The circulation pipe 6 can absorb the alcohol vapor that has not been condensed and liquefied on the lower side of the condenser 5 and then discharge it into the cavity 9. The alcohol vapor in the cavity 9 will be discharged into the gas storage chamber 16 through the rear end of the installation frame 8. The alcohol vapor will flow in the inner cavity of the gas storage chamber 16. These alcohol vapors will eventually be discharged downward through the blowing hole 10 and blow directly on the outer wall of the condenser 5, thereby achieving a circulation effect. The uncondensed alcohol vapor can be brought into contact with the condenser 5 again through the action of the suction fan 7, which increases the chance and time of contact between the steam and the surface of the condenser 5, which helps to ensure It ensures that more alcohol vapor can be fully condensed, maximizes the recovery of alcohol components in the alcohol vapor, reduces product losses due to incomplete condensation, improves overall condensation efficiency and resource utilization, and can achieve a higher condensation rate without significantly increasing energy consumption, which has an energy-saving effect; when these alcohol vapors are blown toward the outer wall of the condenser tube 5 through the blowing hole 10, the alcohol vapor will blow toward the alcohol droplets on the outer wall of the condenser tube 5, which can increase the kinetic energy of these droplets and make it easier for them to slide along the tube wall of the condenser tube 5, which helps to prevent the droplets from accumulating to form larger water droplets, reduces the thickness of the liquid film, thereby improving the heat exchange effect, and then increasing the space and efficiency of subsequent steam condensation.

[0036] like Figure 4 and Figure 5As shown, slide bars 17 are evenly slidably installed on the mounting frame 8 , a round block 18 is fixedly installed at the bottom end of each group of slide bars 17 , and a reset spring 19 is fixedly installed between each group of round blocks 18 and the bottom of the mounting frame 8 .

[0037] A magnet block 20 is fixedly mounted on the top of each group of slide bars 17 and the bottom of the cross plate 15 , and two adjacent groups of magnet blocks 20 are magnetically mounted.

[0038] When the motor 14 drives the cross plate 15 to rotate, the cross plate 15 will drive the groups of magnet blocks 20 at its bottom to rotate synchronously. When the magnet block 20 at the bottom of the cross plate 15 breaks away from the magnet block 20 at the top of the slide bar 17, the magnetic attraction of the two groups of magnet blocks 20 is gone. Under the action of the reset spring 19, the reset spring 19 returns to its initial state and pushes the round block 18 to move downward to its initial position. The round block 18 will hit the top of the condenser tube 5. The movement of the round block 18 will slide on the mounting frame 8 through the slide bar 17. When the magnet block 20 on the cross plate 15 moves to the upper side of the magnet block 20 on the slide bar 17 again, the two groups of magnet blocks 20 enter the magnetic attraction range and the two groups of magnet blocks 20 will be magnetically attracted together. At this time, the lower magnet block 20 will pass through the slide bar 17 drives the round block 18 to move upward away from the top of the condenser 5 and squeezes the reset spring 19. At this time, during the rotation of the cross plate 15, the round blocks 18 of each group 18 can reciprocate and hit the top of the condenser 5, which can cause the condenser 5 to vibrate, thereby improving the fluidity of the alcohol droplets, prompting the already formed alcohol droplets to fall off from the surface of the condenser 5 faster, improving the collection efficiency, and reducing the residence time of the droplets on the tube wall. More condensation surface area can be freed up for new alcohol vapor to condense, thereby improving the overall condensation efficiency. At the same time, it helps to break up the local liquid accumulation or liquid film that may be formed, so that the alcohol vapor can more evenly contact the entire surface of the condenser 5 instead of concentrating in certain areas, which is conducive to improving the heat exchange efficiency.

[0039] like Figure 4 and Figure 5 As shown, a conical cover 21 is provided on the lower side of each group of blowing holes 10, and each group of conical covers 21 is fixedly installed on the bottom of the mounting frame 8. A guide rod 22 is provided in each group of conical covers 21, and the top end of each group of guide rods 22 is fixedly installed on the inner cavity top wall of the air storage cavity 16, and the bottom end of each group of guide rods 22 is contacted with the top of the condenser 5.

[0040] A funnel 23 is provided on the lower side of the condensing tube 5 , and the funnel 23 is fixedly mounted on the inner wall of the recovery box 1 .

[0041] A vertical pipe 24 is fixedly installed at the bottom end of the funnel 23 , and a drainage pipe 25 is fixedly installed at one side of the bottom of the recovery box 1 .

[0042] When the alcohol vapor is discharged downward, the conical cover 21 can be used to diffuse the discharged alcohol vapor, thereby increasing the discharge area of ​​the alcohol vapor. The guide rod 22 can be used to guide part of the alcohol vapor discharged from the conical cover 21 to the top of the condenser 5, thereby guiding the flow. The alcohol droplets on the outer wall of the condenser 5 will fall into the funnel 23 when discharged, and the alcohol droplets will eventually flow along the funnel 23 and finally flow through the vertical pipe 24 to the bottom wall of the inner cavity of the recovery box 1 for collection. A valve is installed in the drain pipe 25. In the initial state, the valve is closed to make the recovery box 1 sealed. When the valve is opened, the alcohol liquid recovered in the recovery box 1 can be taken out for subsequent processes.

[0043] like Figure 4 and Figure 5 As shown, each group of reset springs 19 is initially in a compressed state, and the magnetic attraction force of two adjacent groups of magnet blocks 20 is greater than the elastic force of the reset springs 19 .

[0044] Each group of sliding rods 17 and each group of magnet blocks 20 in the horizontal direction are arranged in a circular array.

[0045] The annular frame 2 and the protective frame 13 are both made of heat-insulating materials.

[0046] The magnetic attraction force of the two adjacent groups of magnet blocks 20 is greater than the elastic force of the reset spring 19, so that when the two adjacent groups of magnet blocks 20 are magnetically attracted together, the round block 18 can be pulled upward to facilitate subsequent impact work. The groups of slide bars 17 and the groups of magnet blocks 20 in the horizontal direction are arranged in a circular array, which makes it easy for the upper magnet block 20 to stably absorb the lower magnet block 20 during movement. The annular frame 2 and the protective frame 13 are both made of heat-insulating materials to prevent the heat of alcohol vapor from being transferred to the motor 14, thereby preventing the motor 14 from overheating.

[0047] Working principle: First, connect the connecting pipe 3 to the end of the liquor distillation tower that discharges alcohol vapor, then connect the output end of external cold water to the water inlet end 11, and connect the pipe for recovering hot water after heat exchange to the drainage end 12. The cold water will flow in the condenser 5, making it form a low-temperature state. The alcohol vapor will be discharged into the annular frame 2 through the connecting pipe 3, and then flow downward into the recovery box 1 through the through port 4. The control motor 14 drives the cross plate 15 to rotate, which can disperse and diffuse the alcohol vapor. The diffused alcohol vapor will be evenly distributed on the condenser 5 to realize heat exchange. The alcohol vapor after heat exchange will form liquid alcohol droplets on the outer wall of the condenser 5. Turn on the suction fan 7 to make The circulation pipe 6 reciprocates to absorb the uncondensed alcohol vapor on the lower side of the condenser 5, and then discharges it into the air storage chamber 16, and blows it downward on the outer wall of the condenser 5 through the blowing hole 10 again to realize a reciprocating cycle. At the same time, the blowing force of the blowing hole 10 can quickly blow off and collect the alcohol droplets on the outer wall of the condenser 5. During the rotation of the cross plate 15, the cooperation of the magnet block 20 and the return spring 19 can make the round block 18 reciprocate and hit the condenser 5, which can further shake off the alcohol droplets on the outer wall of the condenser 5 for collection. The fallen alcohol droplets will flow to the bottom wall of the inner cavity of the recovery box 1 for collection. The alcohol liquid collected in the recovery box 1 can be taken out by opening the valve on the drain pipe 25.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
