[0038] In the description of the utility model, the meaning of several is one or more, and the meaning of multiple is more than two, greater than, less than, more than, etc. are understood as not including the number, and above, below, etc. are understood as including the number.

[0039] The utility model provides a kind of condensing device, for by the way of heat exchange with cooling medium, to make high-temperature gaseous material condensation conversion into liquid material. The gaseous material in the present application can be used as wine steam, and the liquid material corresponds to base liquor.

[0040] As Figures 1 to 5The condensing device of the present application comprises a shell 1, a first tube box 2, a distribution plate 2 and a plurality of heat exchange pipes 4, the shell 1 encloses a heat exchange space 11, the first tube box 2 is arranged at the top or bottom of the shell 1, the distribution plate 2 separates the first liquid cavity 21 on the first tube box 2 into a first liquid cavity 211 and a second liquid cavity 212, the heat exchange pipes 4 are located in the heat exchange space 11, one end of the heat exchange pipes 4 is communicated with the second liquid cavity 212, and the other end of the heat exchange pipes 4 extends vertically and penetrates out of the shell 1 in a direction away from the first tube box 2. After the heat exchange medium enters the first liquid cavity 21 of the first tube box 2, the separation of the distribution plate 2 allows part of the heat exchange medium to be temporarily intercepted in the first liquid cavity 211, and the intercepted heat exchange medium is more evenly distributed on the distribution plate 2, then flows to the second liquid cavity 212 through a plurality of through holes 31 on the distribution plate 2, and then enters the heat exchange pipes 4 and exchanges heat with the gas material in the heat exchange space 11 of the shell 1, and then is discharged to the outside to condense the gas material into liquid material.

[0041] The design of the distribution plate 2 not only avoids the direct impact of the cooling medium on the heat exchange pipes 4, but also delays the residence time of the cooling medium, reduces the flow dead zone, and uniformly enters the cooling medium into each heat exchange pipe 4, thereby improving the heat exchange time between the cooling medium and the gas in the heat exchange space 11. Moreover, the distribution plate 2 allows the cooling medium to be fully dispersed before entering the heat exchange pipes 4, so that the flow of the cooling medium entering each heat exchange pipe 4 is more uniform, reduces the temperature difference between the cooling medium and the gas material during the heat exchange process, makes the heat exchange more sufficient, and improves the heat exchange efficiency.

[0042] Figure 1 The structure of the condensing device is shown. Figure 2 The structure of the upper tube box is shown. Figure 3 The top perspective view of the condensing device is shown. For ease of description, the vertical direction in the text corresponds to the figure and the following up and down directions.

[0043] Referring to Figure 1 The condensing device comprises a shell 1, which extends vertically and encloses a heat exchange space 11. The heat exchange space 11 enclosed by the shell 1 can be in the shape of a cylinder, but is not limited thereto, and can also be in the shape of a prism, a platform, etc. other than a cylinder, which can be set according to actual conditions.

[0044] The side wall of the shell 1 is provided with an air inlet 12 at the top, and the side wall of the shell 1 is provided with a liquid outlet 13 at the bottom.

[0045] The air inlet 12 is located above the center line of the shell 1 in the vertical direction and is communicated with the top of the heat exchange space 11. The air inlet 12 can be connected with a structure for generating gas material, such as a Lyne arm on a distiller, to obtain gas material for the heat exchange space 11.

[0046] The liquid outlet 13 is located below the center line of the shell 1 in the vertical direction and communicates with the bottom of the heat exchange space 11. The liquid outlet 13 is lower than the gas inlet 12, so that the condensed liquid material can naturally gather at the bottom of the heat exchange space 11 and be discharged out of the condensing device.

[0047] Further, the shell 1 further comprises a cylinder 14 and a gas inlet cover 15. The cylinder 14 surrounds the heat exchange space 11 inside, and the peripheral wall of the cylinder 14 is provided with a plurality of air passing holes 141. The gas inlet cover 15 is arranged on the upper part of the side wall of the cylinder 14, and the inner peripheral wall of the gas inlet cover 15 is spaced from the outer peripheral wall of the cylinder 14 to form an air charging chamber 151. The air charging chamber 151 communicates with the heat exchange space 11 through the air passing holes 141. The gas inlet 12 is arranged on the side wall of the gas inlet cover 15, and the liquid outlet 13 is arranged at the bottom of the side wall of the cylinder 14.

[0048] Specifically, the gas inlet cover 15 is arranged only on the top of the side wall of the cylinder 14, and the inner peripheral wall of the gas inlet cover 15 is spaced from the top outer peripheral wall of the shell 1 to form an annular air charging chamber 151. When the gaseous material enters the air charging chamber 151, it fills the entire air charging chamber 151 and then uniformly enters the heat exchange space 11 from the air passing holes 141 on the outer peripheral wall of the shell 1. This allows the gaseous material to enter the heat exchange space 11 uniformly from the circumferential direction, so that the gaseous material can stably and uniformly contact the outer surfaces of the various heat exchange tubes 4 in the heat exchange space 11 and exchange heat with the cooling medium in the heat exchange tubes 4. This improves the efficiency of heat exchange of the gaseous raw material and reduces the resistance of heat transfer, realizes sufficient heat exchange, reduces the consumption of the cooling medium, and avoids the situation that the gaseous raw material can only enter the heat exchange space 11 through the air passing holes 141 opposite to the gas inlet 12. The condensed liquid material flows out from the bottom liquid outlet 13 of the cylinder 14.

[0049] In the embodiment of the present disclosure, the plurality of air passing holes 141 on the cylinder 14 are arranged at intervals on the peripheral wall of the cylinder 14, and the diameter of the air passing holes 141 is smaller than the diameter of the gas inlet 12. Therefore, the rate at which the gaseous material enters the air charging chamber 151 is greater than the rate at which the gaseous material enters the heat exchange space 11 through the air passing holes 141. This allows part of the gaseous material to accumulate in the air charging chamber 151 after entering the air charging chamber 151 through the gas inlet 12. When the amount of gaseous material in the air charging chamber 151 reaches a certain amount, the air pressure in the air charging chamber 151 increases. In addition, by allowing the gaseous material to enter the heat exchange space 11 uniformly, the temperature fluctuation inside the shell 1 can be reduced, thereby improving the stability of the condensing process of the condensing device.

[0050] At least one expansion joint 142 is formed on the outer peripheral wall of the cylinder 14. The expansion joint 142 is arranged on the cylinder 14 to compensate for the expansion difference between the heat exchange tubes 4 and the cylinder 14 due to different wall temperatures, thereby reducing the temperature difference stress of the cylinder 14 and improving safety.

[0051] Furthermore, the condensation device also includes a first tube box 2, a distribution plate 2, and multiple heat exchange tubes 4.

[0052] The first tube box 2 is located on the top of the shell 1. A first liquid inlet chamber 21 for the entry of cooling medium is constructed inside the first tube box 2. The first liquid inlet chamber 21 is independent of the heat exchange space 11. The first tube box 2 is provided with a medium inlet 22 for the entry of cooling medium.

[0053] The distribution plate 2 is installed inside the first pipe box 2. For example... Figure 2 As shown, the distribution plate 2 is horizontally spaced across the first liquid inlet chamber 21, dividing the first liquid inlet chamber 21 into a first liquid chamber 211 and a second liquid chamber 212. The medium inlet 22 is connected to the first liquid chamber 211. The distribution plate 2 is provided with a plurality of vertically penetrating through holes 31 to allow the cooling medium to enter from the first liquid chamber 211 and pass through the through holes 31 into the second liquid chamber 212.

[0054] Multiple heat exchange tubes 4 are spaced apart in the heat exchange space 11. The heat exchange tubes 4 extend vertically, with the upper end of the heat exchange tube 4 passing through the shell 1 upward and communicating with the second liquid chamber 212, and the lower end of the heat exchange tube 4 passing through the shell 1 downward.

[0055] Specifically, the cooling medium flows downwards under its own weight. After entering the first liquid inlet chamber 21, it passes through the first liquid chamber 211 and the second liquid chamber 212 before entering the heat exchange tube 4. Due to the distribution plate 2, the cooling medium is blocked by the distribution plate 2 before entering the second liquid chamber 212, so that the cooling medium is first evenly distributed on the distribution plate 2 and then enters each heat exchange tube 4 through multiple through holes 31. Multiple heat exchange tubes 4 are used for the passage of the cooling medium, which can exchange heat with the gas in the heat exchange space 11, condensing the gas entering the heat exchange space 11 into liquid.

[0056] The design of the distribution plate 2 avoids direct impact or even penetration of the cooling medium into the heat exchange tubes 4. This not only slows down the residence time of the cooling medium, reducing flow non-uniformity and dead zones, but also ensures a uniform flow rate of the cooling medium entering each heat exchange tube 4, increasing the heat exchange time between the cooling medium and the gas in the heat exchange space 11, achieving sufficient heat exchange and improving heat exchange efficiency. Furthermore, it reduces the risk of impact and wear on the heat exchange tubes 4, extending their service life. Simultaneously, the distribution plate 2 evenly distributes the cooling medium across multiple heat exchange tubes 4, ensuring sufficient dispersion before entering each tube. This results in a more uniform flow rate within each heat exchange tube 4, guaranteeing a similar flow rate for each tube, reducing the temperature difference during heat exchange between the cooling medium and the gaseous material, leading to more complete heat exchange and further improving heat exchange efficiency.

[0057] It can be seen that by means of the through holes 31 on the distribution plate 2, the flow characteristics of the cooling medium can be optimized, the flow rate of the cooling medium at the inlet of the heat exchange tube 4 can be slowed down, and the flow of the cooling medium into each heat exchange tube 4 can be made uniform, so that the heat exchange efficiency is improved.

[0058] In combination Figure 2 The distribution plate 2 extends horizontally, and the distribution plate 2 is welded to the inner wall of the first tube box 2 through the outer periphery to fix the distribution plate 2. There is a gap between the top surface of the distribution plate 2 and the inner top surface of the first tube box 2 to form a first liquid cavity 211. There is a gap between the bottom surface of the distribution plate 2 and the end port of the heat exchange tube 4 and the shell 1 to form a second liquid cavity 212.

[0059] Referring to Figure 3 Further, the plurality of through holes 31 are staggered with the one end port of the plurality of heat exchange tubes 4.

[0060] Specifically, the through holes 31 are staggered with the heat exchange tubes 4 up and down, so as to avoid that the cooling medium after passing through the through holes 31 directly enters the inlet of the heat exchange tube 4, to promote the cooling medium to form a more sufficient distribution effect before entering the plurality of heat exchange tubes 4, to further hinder and slow down the flow of the cooling medium, to more uniformly distribute the flow of the cooling medium in each heat exchange tube 4, to help improve the heat exchange efficiency, and to improve the quality stability of the product. Moreover, by staggering the positions of the through holes 31 and the heat exchange tubes 4, the flow rate of the cooling medium is effectively reduced, which not only promotes the sufficient heat exchange between the cooling medium in the heat exchange tube 4 and the gas material in the heat exchange space 11, but also helps to prevent the impact and wear of the fluid to the heat exchange tube 4, to prolong the service life of the equipment. In the embodiment, all the heat exchange tubes 4 are staggered with all the through holes 31.

[0061] In another embodiment, some of the through holes 31 can be directly opposite the heat exchange tubes 4. Specifically, the through holes 31 directly opposite the heat exchange tubes 4 can be located at the periphery of the distribution plate 2, i.e. close to the inner wall of the shell 1.

[0062] Further, the inner diameter of the through holes 31 is smaller than the inner diameter of the heat exchange tubes 4. Specifically, the inner diameter of the through holes 31 is smaller, so that the flow of the heat exchange medium passing through the through holes 31 is reduced, the delivery flow of the cooling medium is further slowed down, the cooling medium can be first accumulated on the distribution plate 2, so that the edge through holes 31 of the distribution plate 2 can cover the cooling medium, the distribution effect of the distribution plate 2 on the cooling medium is improved, the cooling medium can uniformly pass through the plurality of through holes 31 on the distribution plate 2, the flow of the cooling medium in each heat exchange tube 4 is more uniformly distributed, which helps to improve the heat exchange efficiency and improves the quality stability of the product.

[0063] Figure 4 The specific structure of the distribution plate 2 is shown.

[0064] As Figure 4As shown, the inner diameter of the through hole 31 located at the periphery of the distribution plate 2 is smaller than the inner diameter of the through hole 31 located at the middle of the distribution plate 2.

[0065] Specifically, the cooling medium will reduce the flow rate under the action of the viscous force of the inner wall of the shell 1. In this embodiment, the inner diameter of the through hole 31 located at the edge of the distribution plate 2 is smaller than the inner diameter of the through hole 31 located at the middle of the distribution plate 2, which can increase the flow rate of the cooling medium flowing through the through hole 31 at the periphery of the distribution plate 2, so that the flow rate of the cooling medium after passing through the distribution plate 2 tends to be uniform, and the occurrence of turbulent flow is reduced.

[0066] It should be noted that the position located at the middle of the distribution plate 2 is actually a part of the distribution plate 2 with a certain diameter range after removing the edge, rather than only referring to the center point of the distribution plate 2.

[0067] Further, the inner diameters of different through holes 31 gradually decrease from the center to the edge along the radial direction of the distribution plate 2. The smaller the through hole 31 that the cooling medium flows through, the faster the flow rate of the cooling medium. By setting the through hole 31 with a smaller inner diameter towards the edge of the distribution plate 2 on the distribution plate 2, the flow rate of the cooling medium after passing through the distribution plate 2 can be further made to tend to be uniform, and the occurrence of turbulent flow is reduced.

[0068] In addition, the inner diameters of the plurality of through holes 31 on the distribution plate 2 can be consistent or partially different.

[0069] In some embodiments, the inner diameter of the through hole 31 is 2mm-8mm.

[0070] In this embodiment, the through hole 31 includes a first through hole 311, a second through hole 312, and a third through hole 313. The plurality of through holes 31 located at the middle of the distribution plate 2 are the first through holes 311, the inner diameter of which is 6mm. The plurality of second through holes 312 are arranged around the outer periphery of all the first through holes 311, and the inner diameter of the second through hole 312 is 3mm. The plurality of third through holes 313 are arranged around the outer periphery of all the second through holes 312, and the third through hole 313 is closer to the edge of the distribution plate 2 than the second through hole 312, and the inner diameter of the third through hole 313 is 2mm. The inner diameters of the first through hole 311, the second through hole 312, and the third through hole 313 gradually decrease. In fact, the inner diameters of the first through hole 311, the second through hole 312, and the third through hole 313 can also be within other values of 2mm-8mm, which is not specifically limited in this embodiment.

[0071] The inner diameter of the pipe opening of the corresponding heat exchange pipe 4 is larger than the inner diameter of the through hole 31, so as to enable the cooling medium to enter and increase the heat exchange area between the cooling medium in the heat exchange pipe 4 and the gas material in the heat exchange space 11. The heat exchange pipe 4 in this embodiment can be selected in different specifications, and the inner diameter of the corresponding pipe opening has differences. The specific setting can be made according to the actual working condition and the product required.

[0072] Further, the part of the tube opening of the heat exchange pipe 4 vertically opposite to the distribution plate 2 is the flow blocking area 32, and a plurality of through holes 31 are arranged at intervals on the outer periphery of each flow blocking area 32. Specifically, the flow blocking area 32 is a part of the plate body of the distribution plate 2, and the tube opening of the heat exchange pipe 4 is opposite to the distribution plate 2, so that the positions of the through holes 31 are staggered with the heat exchange pipe 4. The cooling medium entering the first liquid inlet cavity 21 of the first tube box 2 will be blocked by the flow blocking area 32 first, so as to prevent the cooling medium from directly impacting the heat exchange pipe 4. In addition, the plurality of through holes 31 are arranged at intervals around the flow blocking area 32, so that the flow of the cooling medium passing through the outer periphery of each flow blocking area 32 is relatively uniform, which can further uniformly distribute the cooling medium to the plurality of heat exchange pipes 4, ensure that each heat exchange pipe 4 can obtain similar flow, reduce the temperature difference between the cooling medium and the gas material in the heat exchange process, make the heat exchange more sufficient, and further improve the heat exchange efficiency.

[0073] In the embodiment, the plurality of flow blocking areas 32 are closely distributed in a honeycomb-like shape to adapt to the positions of the tube openings of the plurality of heat exchange pipes 4. The outer periphery of one flow blocking area 32 surrounds six through holes 31, and the through holes 31 used for spacing between adjacent flow blocking areas 32 are shared. In the embodiment, the outer periphery of one flow blocking area 32 can be adjacent to six other flow blocking areas 32. In addition, the outer periphery of each flow blocking area 32 can also surround three, four, five, six or more through holes 31, which is not specifically limited in the embodiment. The cross section of the through hole 31 can be circular, oval, polygonal, etc.

[0074] Figure 5 A condensing device in another embodiment is shown.

[0075] Further, the condensing device further comprises a second tube box 5. The second tube box 5 is arranged at the bottom and the top of the shell 1 separately from the first tube box 2, and a liquid collecting cavity 51 independent of the heat exchange space 11 is constructed in the second tube box 5; the heat exchange pipe 4 comprises at least one first heat exchange pipe 4, the top end tube opening of the first heat exchange pipe 4 is communicated with the second liquid cavity 212, and the bottom end tube opening of the first heat exchange pipe 4 penetrates the shell 1 downward and is communicated with the liquid collecting cavity 51.

[0076] The liquid collecting cavity 51 can output the cooling medium outward. The second liquid cavity 212, the first heat exchange pipe 4 and the liquid collecting cavity 51 constitute a first channel for the flow of the cooling medium.

[0077] In some embodiments, the first tube box 2 can be welded or fixed on the top of the shell 1 by bolts and flanges.

Specifically, the first channel and the third channel form two parallel and independent flow channels, and the heat exchange medium can be introduced into the two channels respectively, so that the temperature in the heat exchange space 11 is more uniform, and the heat exchange efficiency is improved. In fact, the heat exchange medium introduced into the first channel and the third channel can be different media or different temperatures. In another embodiment, the flow directions of the heat exchange medium in the first channel and the third channel can be parallel upward, parallel downward or opposite, and at this time, the second liquid inlet cavity 24 is used for the outlet of the cooling medium, and the liquid outlet cavity 52 is used for the inlet of the cooling medium. In addition, the second liquid inlet cavity 24 can also be transversely separated by a partition plate 2 or other flow blocking structure.

[0083] The first tube box 2 can include two separate tank shells which respectively form the first liquid inlet cavity 21 and the liquid return cavity 23. Alternatively, the first tube box 2 includes a tank shell which simultaneously forms the first liquid inlet cavity 21 and the liquid return cavity 23.

[0085] Specifically, the position of the baffle plate 6 is lower than the position of the gas inlet cover 15, and the cross-sectional area of the baffle plate 6 is smaller than the cross-sectional area of the heat exchange space 11, so that the plurality of baffle plates 6 can be reciprocally staggered on the opposite sides inside the shell 1, and the gas material can flow reciprocally above the plurality of baffle plates 6 in sequence, thereby prolonging the flow distance of the gas material in the heat exchange space 11, slowing down the flow of the gas material, and allowing the gas material to fully exchange heat with the cooling medium in the plurality of heat exchange tubes 4, thereby improving the condensation effect of the condensing device. Moreover, the heat exchange tube 4 can be arranged through the baffle plate 6, so that the baffle plate 6 can be used to strengthen the support of the heat exchange tube 4, thereby reducing the shaking of the heat exchange tube 4 and the risk of deformation and damage of the heat exchange tube 4.

[0086] In addition, the baffle plate 6 of the present application is supported by at least two support members 61, further improving the installation stability of the baffle plate 6.

The support rod and the baffle plate 6 can also be fixedly connected by welding or bolt connection. In fact, there can be a gap between the baffle plate 6 and the inner side wall of the shell 1, or part of the baffle plate 6 is fixedly connected to the inner side wall of the shell 1.

The first tube box 2 of the condensing device is arranged at the top of the shell 1, and the cooling medium is water, which passes through the heat exchange tube 4 from top to bottom and absorbs the heat of the heat exchange space 11. The heat recovery device receives the cooling medium after passing through the heat exchange tube 4, heats the cooling medium to form water vapor, and then discharges the water vapor.

[0088] Specifically, the temperature of the cooling medium is increased after heat exchange with the gas material in the condensing device, and only a small amount of energy is needed to heat the cooling medium to form steam in the heat recovery device. The water vapor formed by heating can flow to the distiller located upstream of the condensing device for reuse. In addition to meeting the normal condensation requirements of the original wine steam, the warm water from the heat exchange tube 4 can be slightly heated to become steam, realizing the recycling of steam and saving the energy efficiency of the entire system.

[0089] In specific embodiments, the cooling medium of the present application is liquid water, and the medium inlet 22 can enter normal temperature water or warm water at other temperatures, and can form warm water or hot water with higher temperature after heat exchange with the original wine steam. In addition, the cooling medium can also be other cooling media capable of heat exchange with high-temperature wine steam.
