[0048] The application provides a condenser, which is used for condensing gaseous material into liquid material by heat exchange between the gaseous material in the condenser and two independent and opposite cooling medium flow channels.

[0049] Referring to Figures 1 to 7 The condenser comprises a shell 1, a first pipe box 2 arranged at the bottom of the shell 1, a second pipe box 3 arranged at the top of the shell 1, a first heat exchange group and a second heat exchange group. The shell 1 is vertically penetrated and surrounds a heat exchange space 111, the top of the side wall of the shell 1 is provided with an air inlet 112, and the bottom of the side wall of the shell 1 is provided with a liquid outlet 113. A first cavity 21 for entering cooling medium is constructed in the first pipe box 2, and the first cavity 21 and the heat exchange space 111 are independent of each other. A second cavity 31 for entering cooling medium is constructed in the second pipe box 3, and the first cavity 21, the second cavity 31 and the heat exchange space 111 are independent of each other. The first heat exchange group is located in the heat exchange space 111 and comprises a plurality of first heat exchange pipes 4, the plurality of first heat exchange pipes 4 are arranged at intervals and extend vertically, the bottom end pipe opening of the first heat exchange pipe 4 penetrates the shell 1 downward and is communicated with the first cavity 21, and the top end pipe opening of the first heat exchange pipe 4 penetrates the shell 1 upward. The second heat exchange group is located in the heat exchange space 111 and comprises a plurality of second heat exchange pipes 5, the plurality of second heat exchange pipes 5 are arranged at intervals and extend vertically, the top end pipe opening of the second heat exchange pipe 5 penetrates the shell 1 upward and is communicated with the second cavity 31, and the bottom end pipe opening of the second heat exchange pipe 5 penetrates the shell 1 downward. The first heat exchange pipe 4 and the second heat exchange pipe 5 are used for passing cooling medium, part of the cooling medium can pass through the first cavity 21 and pass through the plurality of first heat exchange pipes 4 from bottom to top, and the other part of the cooling medium can pass through the second cavity 31 and pass through the plurality of second heat exchange pipes 5 from top to bottom. When the cooling medium passes through the first heat exchange pipe 4 and the second heat exchange pipe 5, the cooling medium can exchange heat with the gas in the heat exchange space 111 and condense the gas in the heat exchange space 111 into liquid.

[0050] The first cavity 21 and the first heat exchange pipe 4 form a cooling medium flow channel, and the second cavity 31 and the second heat exchange pipe 5 form another cooling medium flow channel. By arranging two independent cooling medium flow channels in the heat exchange space 111 inside the condenser, the temperature inside the condenser can be precisely controlled and managed. By independently controlling the flow of cooling medium in each cooling medium flow channel, the heat exchange demand can be optimized. If the temperature of the area responsible for one cooling medium flow channel is relatively high, the flow of the channel can be increased to balance the temperature in the entire heat exchange space 111. If the temperature of the area responsible for one cooling medium flow channel is too low, the flow of the channel can be reduced to ensure that each part of the condenser is properly cooled, preventing excessive or insufficient cooling in some areas, and improving heat exchange efficiency.

[0051] Meanwhile, the directions of the two independent cooling medium flow channels are opposite, and the medium inlet positions of the two cooling medium flow channels are staggered, further balancing the internal temperature difference of the heat exchange space 111, improving the uniformity of heat exchange between the gas material and the cooling medium, achieving sufficient heat exchange, improving heat exchange efficiency, and making the properties of the condensed liquid material product more stable.

[0052] In actual use, the two independent cooling medium flow channels have different medium outlets, and the staff can plan and utilize the cooling medium after heat exchange according to the position of the cooling medium outlet. Meanwhile, the staff can also select different temperatures or different substances of the cooling medium according to the required condensed product. Different temperatures of the cooling medium can form a specific temperature gradient in the condenser, and can form a temperature change from high temperature to low temperature inside the condenser, so that the gas material can be more fully exchanged with the cooling medium during the condensation process, thereby improving the condensation efficiency and allowing more gas to be quickly and effectively converted into liquid whiskey to meet diversified production needs. In addition, when the condenser fails, planning the interior of the condenser into two different cooling medium flow channels can help the staff quickly locate the cooling medium flow channel area where the problem belongs, facilitating timely troubleshooting and repair.

[0053] Figure 1 The structure of the condenser is shown.

[0054] Referring to Figure 1 The condensing device comprises a shell 1, which extends vertically and surrounds a heat exchange space 111. The heat exchange space 111 surrounded by the shell 1 can be in the shape of a cylinder, but is not limited thereto. The heat exchange space 111 can also be in the shape of a prism, a platform, or the like, which can be set according to actual conditions.

[0055] The top of the side wall of the shell 1 is provided with an air inlet 112, and the bottom of the side wall of the shell 1 is provided with a liquid outlet 113.

[0056] The air inlet 112 is located above the vertical centerline of the housing 1 and communicates with the top of the heat exchange space 111. The air inlet 112 can be used to connect with a structure that generates gaseous material, such as a Lane arm on a distiller, to obtain gaseous material for the heat exchange space 111.

[0057] The liquid outlet 113 is located below the vertical centerline of the shell 1 and is connected to the bottom of the heat exchange space 111. The liquid outlet 113 is lower than the air inlet 112, so that the liquid material formed after condensation can naturally gather at the bottom of the heat exchange space 111 and be discharged outside the condensation device.

[0058] Furthermore, the shell 1 includes a cylindrical body 12, a first tube sheet 13, and a second tube sheet 14. The cylindrical body 12 extends vertically to form a heat exchange space 111. The first tube sheet 13 is sealed at the bottom opening of the cylindrical body 12. The second tube sheet 14 is sealed at the top opening of the cylindrical body 12.

[0059] Both the first tube sheet 13 and the second tube sheet 14 of this application can be connected to the cylinder 12 by sealing connection methods such as welding.

[0060] like Figure 1 As shown, the condenser also includes a first tube box 2, a second tube box 3, a first heat exchange tube 4, and a second heat exchange tube 5. The first tube box 2 is mounted on a first tube sheet 13, and a first cavity 21 for the entry of the cooling medium is constructed within it. The second tube box 3 is mounted on a second tube sheet 14, and a second cavity 31 for the entry of the cooling medium is constructed within it. The first cavity 21, the second cavity 31, and the heat exchange space 111 are independent of each other. The first heat exchange tube 4 and the second heat exchange tube 5 are located within the heat exchange space 111. The bottom of the first heat exchange tube 4 extends through the first tube sheet 13 and communicates with the first cavity 21, while the top of the first heat exchange tube 4 can be connected to a pipe or cavity for discharging the cooling medium to the outside. The top of the second heat exchange tube 5 extends through the second tube sheet 14 and communicates with the second cavity 31, while the bottom of the second heat exchange tube 5 can be connected to a pipe or cavity for discharging the cooling medium to the outside.

[0061] Figure 2 This is a schematic diagram of the structure of the first tube sheet 13.

[0062] In this embodiment, the first tube sheet 13 has a plate-like structure. The first tube sheet 13 can be detachably connected to the first tube box 2, ensuring convenient maintenance.

[0063] A third connecting portion 131 and a fourth connecting portion 132 are formed on the first tube sheet 13 for connection with the first tube box 2.

[0064] Specifically, the first tube plate 13 is formed with a third connecting portion 131 along a radial direction. The first tube plate 13 is provided with a plurality of first bolt holes 1311 spaced apart along the extending direction of the third connecting portion 131. The third connecting portion 131 of the embodiment extends in a straight line and divides the first tube plate 13 into two parts along the radial direction. The position of the third connecting portion 131 corresponds to the position of the partition between the two cooling medium flow channels, facilitating the partition of the medium inlet and the medium outlet of the two cooling medium flow channels. The two cooling medium flow channels of the embodiment are arranged on opposite sides of the shell 1.

[0065] In fact, the extending direction of the third connecting portion 131 matches the position where the first tube plate 13 and the first tube box 2 are connected. The first tube plate 13 and the first tube box 2 can be connected by multiple bolts at the third connecting portion 131. In other embodiments, the third connecting portion 131 can extend in a straight line, a fold, a curve, etc., and divide the first tube plate 13 into two parts arbitrarily. In fact, the two parts of the first tube plate 13 divided by the third connecting portion 131 cannot be regarded as the distribution positions of the first heat exchange group and the second heat exchange group. In fact, the difference between the first heat exchange tube 4 of the first heat exchange group and the second heat exchange tube 5 is that they are connected to different liquid inlet chambers and liquid outlet chambers. In addition, the first tube plate 13 and the first tube box 2 can also be connected and fixed by welding or irregular bolt connection points.

[0066] In other embodiments, the two cooling medium flow channels can also be arranged in sequence from inside to outside in the shell 1, i.e., one cooling medium flow channel is arranged on the outer periphery of another cooling medium flow channel. By feeding cooling medium of different temperatures into different cooling medium flow channels, the temperature of the cooling medium flow channel located on the outer periphery can be more uniform than that of the cooling medium flow channel located on the inside.

[0067] The outer periphery of the first tube plate 13 extends outward beyond the outer periphery of the cylinder 12 to form a fourth connecting portion 132 connected to the first box shell 23. Specifically, the first tube plate 13 is provided with a plurality of second bolt holes 1321 spaced apart along the extending direction of the fourth connecting portion 132, and a plurality of second bolts are arranged in a circle. The first box shell 23 can be connected to the second bolt holes 1321 by bolts, improving the connection stability of the first box shell 23. The second bolts on the fourth connecting portion 132 are staggered with the heat exchange space 111, reducing material leakage.

[0068] The first tube plate 13 is also provided with a first tube hole 133 and a second tube hole 134 connected to the first heat exchange tube 4 and the second heat exchange tube 5, respectively. The plurality of first tube holes 133 and the plurality of second tube holes 134 are arranged on opposite sides of the third connecting portion 131 and within the fourth connecting portion 132.

[0069] In addition, the structure of the second tube plate 14 can refer to the structure of the first tube plate 13, the third connecting part 131 and the fourth connecting part 132 for connecting with the second tube box 3 are formed on the second tube plate 14, and the first tube hole 133 and the second tube hole 134 for fixing the first heat exchange tube 4 and the second heat exchange tube 5 are formed on the second tube plate 14. In addition, the second tube plate 14 of the embodiment can be detachably connected with the second tube box 3, so that the convenience of maintenance is ensured.

[0070] The shell 1 further comprises an air inlet cover 15. The peripheral wall of the cylinder body 12 is provided with a plurality of air passing holes 121. The air inlet cover 15 is arranged on the upper portion of the side wall of the cylinder body 12, and the inner peripheral wall of the air inlet cover 15 is spaced from the outer peripheral wall of the cylinder body 12 to form an air charging chamber 151, and the air charging chamber 151 is communicated with the heat exchange space 111 through the air passing holes 121. The air inlet 112 is arranged on the side wall of the air inlet cover 15, and the liquid outlet 113 is arranged on the bottom of the side wall of the cylinder body 12.

[0071] Specifically, the air inlet cover 15 is arranged only on the top of the side wall of the cylinder body 12, and the inner peripheral wall of the air inlet cover 15 is spaced from the outer peripheral wall of the top of the shell 1 to form an annular air charging chamber 151. In addition, the shape of the air inlet cover 15 can also be matched with the shell 1 to be arranged in a prism shape or the like. When the gas material enters the air charging chamber 151, it fills the entire air charging chamber 151 and then uniformly enters the heat exchange space 111 from the air passing holes 121 on the outer peripheral wall of the shell 1, so that the gas material can enter the heat exchange space 111 uniformly from the circumferential direction, and the gas material can stably and uniformly contact the outer surfaces of each of the first heat exchange tube 4 and the second heat exchange tube 5 in the heat exchange space 111, and exchange heat with the cooling medium in the heat exchange tube, so as to improve the heat exchange efficiency of the gas material, realize sufficient heat exchange, reduce the consumption of the cooling medium, and avoid the situation that the gas material can only enter the heat exchange space 111 through the air passing holes 121 opposite to the air inlet 112. The condensed liquid material flows out from the bottom liquid outlet 113 of the cylinder body 12.

[0072] As shown in Figure 1 The first tube box 2 is arranged on the bottom of the first tube plate 13, and the first cavity 21 and the third cavity 22 which are independent of the heat exchange space 111 and independent of each other are constructed in the first tube box 2. The second tube box 3 is arranged on the top of the second tube plate 14, and the second cavity 31 and the fourth cavity 32 which are independent of the heat exchange space 111 and independent of each other are constructed in the second tube box 3. In one cooling medium flow channel, the first cavity 21 is used for entering the cooling medium, and the fourth cavity 32 is used for discharging the cooling medium outward. In another cooling medium flow channel, the second cavity 31 is used for entering the cooling medium, and the third cavity 22 is used for discharging the cooling medium.

[0073] Figure 3 The structure of the first tube box 2 is shown in the figure.

[0074] Referring to Figure 3The first tube box 2 comprises a box shell 23, and two recesses 231 are formed on the box shell 23; one of the recesses 231 forms the first cavity 21, and the other recess 231 forms the third cavity 22. The first cavity 21 and the third cavity 22 of the first tube box 2 are integrally arranged on the same box shell 23, which facilitates disassembly and assembly.

[0075] The first connecting portion 232 of the first tube box 2 is in a protruding structure relative to the two recesses 231 on the box shell 23, and the extension direction of the first connecting portion 232 matches the third connecting portion 131 on the first tube plate 13, and the first connecting portion 232 is connected with the third connecting portion 131 through bolts. Correspondingly, the first connecting portion 232 is provided with connecting holes matching the first bolt holes 1311. As shown in Figure 1 the first connecting portion 232 of the first tube box 2 protrudes upward, and the first cavity 21 and the third cavity 22 of the box shell 23 are arranged at intervals to form an avoiding space, which facilitates the bolts to pass through the first connecting portion 232 of the first tube box 2 to be connected with the first tube plate 13.

[0076] The second connecting portion 233 is formed on the outer periphery of the two recesses 231 away from each other on the box shell 23, and the first connecting portion 232 of the box shell 23 and the second connecting portion 233 on the first tube plate 13 are detachably connected with the shell 1 through bolts. The second connecting portion 233 forms an annular structure around the two recesses 231, and the shape of the second connecting portion 233 matches the fourth connecting portion 132 on the first tube plate 13 and can be connected through bolts. Correspondingly, the second connecting portion 233 is provided with connecting holes matching the second bolt holes 1321.

[0077] Further, the first tube box 2 is provided with a first medium inlet 25 corresponding to the first cavity 21, and a second medium outlet 26 corresponding to the third cavity 22, and the first tube box 2 is provided with a blowdown port 24 corresponding to the positions of the first cavity 21 and the third cavity 22.

[0078] In some other embodiments, the first tube box 2 can further comprise two box bodies, one of which is recessed to form the first cavity 21, and the other of which is recessed to form the third cavity 22. The two box bodies can be independently connected to the first tube plate 13 of the shell 1, or the two box bodies can be connected to the first tube plate 13 after being welded to form a box shell 23.

[0079] Figure 4 FIG. 2 is a structural schematic diagram of the second tube box 3.

[0080] Referring to Figure 4The second tube box 3 comprises a box shell 23, and two recesses 231 are formed on the box shell 23. One of the recesses 231 forms the second cavity 31, and the other of the recesses 231 forms the fourth cavity 32. The second cavity 31 and the fourth cavity 32 of the second tube box 3 are integrally arranged on the same box shell 23, which facilitates disassembly and assembly.

[0094] The axial ends of the plurality of first heat exchange pipes 4 are respectively communicated with a first collecting chamber 611 and a second collecting chamber 621.

[0095] By providing the first partition plate 61 in the first cavity 21 and the second partition plate 62 in the fourth cavity 32, the speed of the cooling medium filling the first cavity 21 and the fourth cavity 32 can be slowed down and hindered, the time for the cooling medium to enter the first heat exchange pipe 4 from the first cavity 21 and be discharged from the fourth cavity 32 inside the cooling medium flow channel is delayed, the flow unevenness and flow dead zone are reduced, the heat exchange time between the cooling medium and the gas in the heat exchange space 111 is improved, full heat exchange is achieved, and the heat exchange efficiency is further improved.

[0096] Further, referring to Figure 5 , the first partition plate 61 and the second partition plate 62 are staggered with each other in vertical projection.

The cooling medium can flow reciprocally in the first collecting chamber 611 and the second collecting chamber 621 to form multi-pipe-pass heat exchange, that is, the cooling medium in part of the first heat exchange pipes 4 flows from top to bottom, and the cooling medium in another part of the first heat exchange pipes 4 flows from bottom to top. The cooling medium can flow between at least two first collecting chambers 611 and second collecting chambers 621 to realize multiple heat exchanges, thereby improving the heat exchange efficiency.

[0097] A first liquid collecting cavity 611 is communicated with a first medium inlet 25 for the cooling medium to enter, and a second liquid collecting cavity 621 is communicated with a first medium outlet 34 for the cooling medium to output externally. The first liquid collecting cavity 611 where the first medium inlet 25 is located and the second liquid collecting cavity 621 where the first medium outlet 34 is located are staggered in vertical projection. The cooling medium entering the first liquid collecting cavity 611 from the first medium inlet 25 is directly discharged externally from the second liquid collecting cavity 621 provided with the first medium outlet 34 through the first heat exchange pipe 4, further increasing the residence time of the cooling medium in the condenser and improving the heat exchange effect.

[0098] Specifically, referring to Figure 5 and Figure 6 , the first partition plate 61 has two, and the two first partition plates 61 divide the first cavity 21 into three first liquid collecting cavities 611, and the three first liquid collecting cavities 611 are respectively a liquid collecting cavity a 6111, a liquid collecting cavity b 6112, and a liquid collecting cavity c 6113. The liquid collecting cavity a 6111 is communicated with the first medium inlet 25 for the cooling medium to enter.

[0099] The second partition plate 62 has two, and the two second partition plates 62 divide the fourth cavity 32 into three second liquid collecting cavities 621, and the three second liquid collecting cavities 621 are respectively a liquid collecting cavity d 6211, a liquid collecting cavity e 6212, and a liquid collecting cavity f 6213. The liquid collecting cavity f 6213 is communicated with the first medium outlet 34 for the cooling medium to output externally.

[0100] As shown in Figure 6 , the first heat exchange pipe 4 includes at least one heat exchange pipe a 41, at least one heat exchange pipe b 42, at least one heat exchange pipe c 43, at least one heat exchange pipe d 44, and at least one heat exchange pipe e 45.

The cooling medium forms a S-shaped reciprocating flowing direction in the cooling medium flow channel formed by the first cavity 21, the first heat exchange pipe 4 and the fourth cavity 32, and the cooling medium can realize multi-pipe pass heat exchange through the plurality of first heat exchange pipes 4, thereby improving the heat exchange efficiency. The bottom of the collecting cavity b 6112 and the collecting cavity c 6113 is respectively provided with a blowdown port 24, and the top of the collecting cavity d 6211 and the collecting cavity e 6212 is respectively communicated with an air exhaust port 33.

The cooling medium can overflow from a first collecting cavity 611 to an adjacent first collecting cavity 611, or from a second collecting cavity 621 to an adjacent second collecting cavity 621, so that the cooling medium has different flowing directions.

[0106] Specifically, the adjacent first collecting cavities 611 can be communicated with each other by providing a through hole 633 on the first partition plate 61, or by providing a gap between the first partition plate 61 and the inner wall of the first tube plate 2 and the first tube plate 13, so that the cooling medium can flow through the plurality of first collecting cavities 611 in turn. The adjacent second collecting cavities 621 can be communicated with each other by providing a through hole 633 on the second partition plate 62, or by providing a gap between the second partition plate 62 and the inner wall of the second tube plate 3 and the second tube plate 14, so that the cooling medium can flow through the plurality of second collecting cavities 621 in turn.

[0107] The first heat exchange pipe 4 is staggered with the first partition plate 61 and the second partition plate 62, and is arranged on both sides of the first partition plate 61 and the second partition plate 62.

[0108] Further, referring to Figure 3 , the first cavity 21 and the third cavity 22 are arranged in sequence along the horizontal transverse direction, and the first partition plate 61 extends along the transverse direction to divide the first cavity 21 into at least two first liquid collecting cavities 611 in the longitudinal direction. Here, the transverse direction and the longitudinal direction are two directions along the horizontal and vertical directions.

[0109] Specifically, the first connecting portion 232 of the first tube box 2 extends along the longitudinal direction and sequentially divides the first cavity 21 and the third cavity 22 along the horizontal transverse direction, the first partition plate 61 is arranged transversely perpendicular to the extension direction of the first connecting portion 232, and two first partition plates 61 are arranged in sequence along the longitudinal direction and divide the first cavity 21 into three first liquid collecting cavities 611 in the longitudinal direction. In other embodiments, the first partition plate 61 and the extension direction of the first connecting portion 232 can be arranged at an acute or obtuse angle.

[0110] Referring to Figure 4 , the second cavity 31 and the fourth cavity 32 are arranged in sequence along the horizontal transverse direction; the second partition plate 62 extends along the transverse direction to divide the fourth cavity 32 into at least two second liquid collecting cavities 621 in the longitudinal direction.

In other embodiments, the first partition plate 61 and the extension direction of the first connecting portion 232 can be arranged at an acute or obtuse angle.

[0112] In this embodiment, the bottom edge and the two lateral edges of the first partition plate 61 are welded to the inner wall of the first tube box 2.

[0113] Figure 7 It is a partial enlarged view of the condenser.

[0114] Referring to Figure 7The flow resistance structure further comprises a distribution plate 63 horizontally arranged in the second cavity 31 and separating the second cavity 31 into an upper liquid cavity 631 and a lower liquid cavity 632, and a plurality of vertical through holes 633 are arranged on the distribution plate 63 to allow the cooling medium to flow from the upper liquid cavity 631 to the lower liquid cavity 632. The top of the second heat exchange pipe 5 is communicated with the lower liquid cavity 632.

[0115] Specifically, the distribution plate 63 horizontally extends, and the cooling medium sequentially passes through the upper liquid cavity 631 and the lower liquid cavity 632 before entering the second heat exchange pipe 5, thereby forming another cooling medium flow channel. Because of the arrangement of the distribution plate 63, the cooling medium needs to be blocked by the distribution plate 63 before entering the lower liquid cavity 632, so that the cooling medium is uniformly distributed on the distribution plate 63 before entering the second heat exchange pipe 5, and the cooling medium is uniformly distributed in the second heat exchange pipe 5, so that the flow of the cooling medium entering each second heat exchange pipe 5 is more uniform, and the flow of each second heat exchange pipe 5 is similar, so that the heat exchange is more sufficient, and the heat exchange efficiency is improved. Moreover, the design of the distribution plate 63 can avoid the direct impact of the cooling medium on the second heat exchange pipe 5, and even the cooling medium can pass through the second heat exchange pipe 5, which not only delays the residence time of the cooling medium, reduces the flow non-uniformity and flow dead zone, and improves the flow rate of the cooling medium entering each second heat exchange pipe 5, improves the heat exchange time between the cooling medium and the gas material in the heat exchange space 111, realizes sufficient heat exchange, further improves the heat exchange efficiency, and reduces the impact and wear risk of the cooling medium on the second heat exchange pipe 5, prolongs the service life of the heat exchange pipe.

[0116] In addition, the distribution plate 63 is welded on the inner wall of the first tube box 2 corresponding to the second cavity 31 by the outer periphery, so as to fix the distribution plate 63.

[0117] Through the through holes 633 on the distribution plate 63, the flow characteristics of the cooling medium can be optimized, the flow rate of the cooling medium at the inlet of the second heat exchange pipe 5 is slowed down, the cooling medium is prevented from directly passing through the second heat exchange pipe 5, and the flow of the cooling medium entering each second heat exchange pipe 5 is uniformed, thereby improving the heat exchange efficiency.

[0118] In specific embodiments, the plurality of through holes 633 on the distribution plate 63 are staggered with the plurality of second heat exchange pipes 5, so as to avoid the cooling medium directly entering the inlet of the second heat exchange pipe 5 after passing through the through holes 633, promote the cooling medium to form more sufficient distribution before entering the plurality of second heat exchange pipes 5, further hinder and slow down the flow of the cooling medium, more uniformly distribute the flow of the cooling medium in each second heat exchange pipe 5, and help to improve the heat exchange efficiency and improve the quality stability of the product.

[0119] Further, the inner diameter of the through hole 633 is smaller than the inner diameter of the second heat exchange tube 5. Specifically, the inner diameter of the through hole 633 is smaller, so that the flow rate of the heat exchange medium passing through the through hole 633 is reduced, further delaying the delivery flow rate of the cooling medium, so that the cooling medium can first accumulate on the distribution plate 63, so that the cooling medium can cover the edge through hole 633 of the distribution plate 63, improve the distribution effect of the distribution plate 63 on the cooling medium, and the cooling medium can be uniformly passed through the multiple through holes 633 on the distribution plate 63, more evenly distribute the flow rate of the cooling medium in each second heat exchange tube 5, help to improve the heat exchange efficiency, and improve the quality stability of the product.

[0120] The cooling medium passing from top to bottom through the second cavity 31, the second heat exchange tube 5, and the third cavity 22 has a higher temperature after heat exchange with the gas material in the condenser. The outlet of the cooling medium is located at the bottom of the condenser, which facilitates the connection of the heat recovery device of the external device.

[0121] In this embodiment, the cooling medium is liquid water, which can actually be other cooling media. During production, cooling media at room temperature, room temperature to 60°C, or higher than 60°C to lower than the temperature of the wine steam can be selected to be introduced into the first cavity 21 and the second cavity 31, so that the temperature of the cooling medium after heat exchange with the gas material is different. If the cooling medium is discharged to the heat recovery device of the external device, cooling media at a higher temperature can be selected to be introduced, and the temperature of the cooling medium after heat exchange with the gas material can reach above 90°C, so that the heat recovery device can heat the cooling medium to form steam by using a small amount of energy. The steam formed by heating can flow to the distiller located upstream of the condenser for reuse, realizing steam recycling and saving the energy efficiency of the entire system, and realizing efficient condensation of whiskey TVR in application.

[0122] The condensing device of the embodiment further comprises multiple baffle plates 7, which are horizontally arranged in the heat exchange space 111. The multiple baffle plates 7 are vertically spaced apart, and the two adjacent baffle plates 7 are staggered along the opposite sides of the shell 1.

[0123] Specifically, the position of the baffle plate 7 is lower than that of the gas inlet cover 15, and the cross-sectional area of the baffle plate 7 is smaller than that of the heat exchange space 111, so that the plurality of baffle plates 7 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 7 in sequence, thereby prolonging the flow distance of the gas material in the heat exchange space 111, so that the gas material flows slowly, so that the gas material can be fully heat-exchanged with the cooling medium in the plurality of first heat exchange pipes 4 and the plurality of second heat exchange pipes 5, thereby improving the condensing effect of the condensing device. In addition, the first heat exchange pipe 4 and the second heat exchange pipe 5 can penetrate the baffle plate 7, and the baffle plate 7 can be used to strengthen the support of the first heat exchange pipe 4 and the second heat exchange pipe 5, so as to reduce the shaking of the first heat exchange pipe 4 and the second heat exchange pipe 5, and reduce the risk of deformation and damage of the first heat exchange pipe 4 and the second heat exchange pipe 5.

[0124] In addition, the baffle plate 7 of the present application is supported by at least two support members, further improving the installation stability of the baffle plate 7. The support member of the present embodiment is a vertical support rod 8, which connects the baffle plate 7 and is spaced apart from the first heat exchange pipe 4 and the second heat exchange pipe 5. The support rod 8 and the baffle plate 7 can also be fixedly connected by a welding connection mode. In fact, there can be a gap between the baffle plate 7 and the inner side wall of the shell 1, or part of the baffle plate 7 is connected and fixed to the inner side wall of the shell 1.

[0125] Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. The application is intended to cover any variations, uses or adaptive changes of this application following, in general, the principles of the application and including such insubstantial variations or changes that are obvious to those skilled in the art.
