[0002] High-quality liquor is naturally derived and brewed with ingenuity. With its unique sweetness and richness, it interprets the gift of nature and the craftsmanship of craftsmen.

However, the actual wine collection stage is only the wine distillation stage, that is, only in the wine distillation stage, the steam escaping from the air outlet of the wine sieve can be condensed to obtain liquor, and the steam escaping from the air outlet of the wine sieve in the other two stages is wasted.

In this embodiment, the medium and low pressure steam can reach the secondary suction of the steam ejector 7 and mix the initial steam and the first wine vapor. The mixed steam enters the distillation pot 1 to achieve the effect of distilling wine. Compared with the prior art, the design of this embodiment is more energy-saving.

[0084] Preferably, a support shaft is erected on the bottom wall of the distillation pot 1, and the support shaft is passed through the tower plate 19 and is connected and fixed to the tower plate 19 to support the tower plate 19. The tower plate 19 and the support shaft can be detachably connected by bolt connection or the like, or can be fixedly connected by welding.

[0085] Figure 2 for Figure 1 Schematic diagram of the AA direction.

[0086] refer to Figure 1 and Figure 2 The tower tray 19 includes a tower plate 191, which is sleeved on a supporting shaft and used for supporting materials.

[0087] Preferably, a plurality of through holes 192 are provided at intervals on the tower plate 191 for passage of the steam in the distillation pot 1. This design increases the airway for the steam on the tower plate 191 to pass through, and can increase the contact porosity between the steam in the distillation pot 1 and the material located on the top of the tower plate 191, so that the steam in the distillation pot 1 can better contact with the material located on the top of the tower plate 191, and better transfer mass and heat, and more efficiently produce the first wine vapor or the second wine vapor, and thus better separate and purify to obtain high-concentration alcohol.

[0088] Specifically, a plurality of through holes 192 are arranged at intervals in the middle of the tower plate 191 , and the plurality of through holes 192 are distributed on the tower plate 191 in a circular array.

[0089] In this embodiment, the ratio of the through holes 192 on the tray 191 is determined according to the vapor-liquid load, and the aperture size of the through holes 192 is set according to the outer diameter characteristics of the material.

[0090] Preferably, the tray 19 includes a plurality of pilot valves 193, and the plurality of pilot valves 193 are disposed at intervals on the tray 191. In this embodiment, the pilot valves 193 are located at the periphery of the plurality of through holes 192.

[0091] In this embodiment, the guide valve 193 is penetrated through the tower plate 191 and is movably connected to the tower plate 191. Specifically, a perforation is provided at the tower plate 191 corresponding to the guide valve 193, and the guide valve 193 is penetrated through the perforation. The guide valve 193 can float up and down relative to the tower plate 191 to open or close the perforation. In practical applications, during the upward movement of the steam in the distillation pot 1, an upward force is given to the guide valve 193. After receiving the upward force, the guide valve 193 floats upward relative to the tower plate 191 to open the perforation, and there is a gap between the guide valve 193 and the tower plate 191, so that part of the steam can escape through the perforation and the gap between the guide valve 193 and the tower plate 191, and continue to move upward and contact with the material.

[0092] In this embodiment, the pilot valve 193 is a float valve.

[0093] Preferably, the guide valve 193 may also be provided with a steam hole for the steam in the distillation pot 1 to pass through. This design can prevent the guide valve 193 from being unable to float up and down relative to the tower plate 19, and can also allow the steam in the distillation pot 1 to pass through; and this design can increase the air passage for the steam on the tower plate 19 to pass through, and can increase the contact porosity between the steam in the distillation pot 1 and the material located on the top of the tower plate 19, so that the steam in the distillation pot 1 can better contact with the material located on the top of the tower plate 19, and better transfer mass and heat, and more efficiently generate the first wine vapor or the second wine vapor, and then better separate and purify to obtain high-concentration alcohol.

[0094] The number of the trays 19 can be one, two or more. When the number of the trays 19 is two or more, the trays 19 are arranged inside the distillation pot 1 at intervals up and down, and are sleeved on the support shaft at intervals up and down, and the tray 19 at the bottom is located above the steam inlet.

[0095] In this embodiment, the number of the trays 19 is two or more as an example for description. At this time, the reflux pipeline 13 refluxes the wine to the tray 19 located at the top.

[0096] Preferably, the tray 19 has a material descending portion 194 and a material receiving portion 195. In two adjacent trays 19, the material descending portion 194 of the upper tray 19 and the material receiving portion 195 of the lower tray 19 are arranged correspondingly up and down, and the projection of the material descending portion 194 of the upper tray 19 falls on the material receiving portion 195 of the lower tray 19. This design enables the material on the upper tray 19 to flow downward to the material receiving portion 195 of the lower tray 19, and perform mass transfer and heat transfer layer by layer, thereby making the wine liquid finally separated more and more pure.

[0097] At this time, the tray 19 may further include a receiving plate 196. The receiving plate 196 is connected to one end of the tray 191, and the top of the receiving plate 196 forms a receiving portion 195. The other end of the tray 191 forms a material drop portion 194. The material drop portion 194 may be formed by opening a material drop hole on the tray 191, or the material drop portion 194 may be formed by a gap between the tray 191 and the inner wall of the distillation pot 1.

[0098] Preferably, in two adjacent layers of tower trays 19, a material lowering plate 21 is protruding from the bottom of the end of the material lowering portion 194 of the upper tower tray 19, and the material lowering plate 21 is used to guide the material on the upper tower tray 19 to flow downward to the material receiving portion 195 of the lower tower tray 19.

[0099] The working principle of the above distillation system is as follows:

[0101] The initial steam from the steam source is transported to the extension pipeline 5 through the transport pipeline 2, and is sprayed upward into the distillation pot 1 through the steam distributor 6, and then a part of the steam moves upward through the through hole 192 on the tower plate 191 and contacts the material on the tower plate 191, a part of the steam moves upward and gives an upward force to the guide valve 193 to open the guide valve 193 and open the perforation, so as to escape from the perforation and the gap between the guide valve 193 and the tower plate 191 and contact the material, and a part of the steam passes through the steam hole on the guide valve 193 and contacts the material.

[0102] After the initial steam is introduced into the distillation pot 1 for a period of time, the first wine vapor is formed in the distillation pot 1 under the full contact between this part of the initial steam and the material, and the first wine vapor enters the delivery pipeline 2 through the steam outlet of the distillation pot 1 and the circulation pipeline 4 in turn, and is refluxed and mixed with the original initial steam in the delivery pipeline 2, and then enters the steam distributor 6 through the extension pipeline 5 together, and is sprayed into the distillation pot 1 under the action of the steam distributor 6, so as to realize the recycling of the first wine vapor.

[0103] As the initial steam and the first wine vapor act on the material, when the distillation system enters the wine distillation stage, the first control valve 8 is closed, the second control valve 10, the first regulating valve 14 and the second regulating valve 12 are opened, and the condenser 3, the flash tank, the cooling tower device 15 and the cooler 18 are opened.

[0104] During the wine distillation stage, the steam in the distillation pot 1 is in full contact with the material, and a second wine vapor is formed in the distillation pot 1. The second wine vapor enters the condenser 3 through the steam outlet, the connecting pipe 9, and the steam inlet of the distillation pot 1 in sequence. At the same time, the cooling water produced by the cooling tower device 15 enters the condenser 3 through the outlet of the cooling tower device 15 and the water inlet of the condenser 3 to exchange heat with the second wine vapor, so that the second wine vapor is condensed to form wine liquid and flows out of the condenser 3 from the infusion port.

[0105] Among them, the cooling water heated after heat exchange enters the flash tank through the water outlet of the condenser 3 and the liquid inlet of the flash tank, and a part of the cooling water is converted into flash steam under the action of the flash tank. The flash steam enters the steam ejector 7 through the steam delivery port of the flash tank and the steam delivery pipeline 17, and after being mixed with the initial steam under the action of the steam ejector 7, it enters the steam ejector through the delivery pipeline 2 and the extension pipeline 5 to realize the recycling of condensed water. In addition, a part of the cooling water can be returned to the cooling tower device 15 through the discharge port of the flash tank and the inlet of the cooling tower device 15, and then reused for a second time.

[0106] Among them, among the wine liquid condensed by the condenser 3, a part of the wine liquid flows back to the top of the tower plate 19 located at the uppermost layer in the distillation pot 1 through the reflux pipe 13 and the reflux port for secondary distillation; a part of the wine liquid enters the cooler 18 through the wine delivery pipe 11 and the liquid inlet of the cooler 18.

[0107] At the same time, the cooling medium produced by the cooling medium generator enters the built-in channel of the cooler 18 from the first end thereof to exchange heat with the wine in the cooler 18, thereby further cooling the wine. The wine then flows into the wine storage container through the liquid outlet and the guide pipe of the cooler 18 for storage. The cooling medium after heat exchange flows back to the cooling medium generator through the second end of the built-in channel to realize the recycling of the cooling medium.

[0108] When the distillation system is in the stage of distilling and distilling wine, the ratio of the flow rate of wine flowing into the cooler 18 and the flow rate of wine returning to the distillation pot 1 can be adjusted by adjusting the valve core opening of the first regulating valve 14 and the second regulating valve 12, thereby adjusting the alcohol concentration of the wine output to the wine storage vessel.

[0109] It can be seen from the above technical solution that the utility model has at least the following advantages and positive effects:

[0110] In the above-mentioned distillation system, by connecting the steam inlet and the steam outlet of the distillation pot, the first wine vapor that cannot meet the needs of making wine liquid can be returned to the distillation pot through the circulation pipeline to heat the material in the distillation pot, thereby realizing the secondary utilization of the first wine vapor and improving the utilization rate of the steam in the distillation system.

[0111] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
