[0039] In order to facilitate the understanding of the present utility model, the present utility model will be further explained and described below with specific embodiments combined with the drawings, and the specific embodiments do not constitute a limitation on the embodiments of the present utility model.

[0040] Those skilled in the art should understand that the drawings are only schematic diagrams of the embodiments, and the components in the drawings are not necessarily necessary for the implementation of the present utility model.

[0041] As Figures 1 to 5 shown, the present utility model embodiment provides a kind of alcohol distillation efficient condensation recovery equipment, including distillation column 1, and the condensing device 2 being communicated with the distillation column 1, the condensing device 2 is communicated with alcohol recovery device 3.Mixed liquor is distilled in distillation column 1, alcohol vapor flows into alcohol recovery device 3 after condensation by condensing device 2, to ensure the safety and stability of the gas pressure in distillation column 1 during distillation, the steam in distillation column 1 can be discharged at any time according to the size of gas pressure.Specifically, the top of distillation column 1 is communicated with adapter pipe 5 by exhaust pipe 4, the radial end surface of adapter pipe 5 is equipped with air outlet hole 6, air outlet hole 6 is communicated with adsorption dilution device 7, the steam in distillation column 1 first enters adapter pipe 5 by exhaust pipe 4, then enters adsorption dilution device 7 by air outlet hole 6 on adapter pipe 5, after steam enters adsorption dilution device 7, it is filtered by the adsorption, dilution effect in adsorption dilution device 7 Odor and harmful gas.

[0042] In order to realize that the gas in distillation column 1 is discharged at any time according to the size of gas pressure, to ensure the pressure safety of distillation column 1, the inside of the adapter pipe 5 is equipped with a blocking valve 8 that can reciprocate axially along the adapter pipe 5, by the axial movement of the blocking valve 8 in the adapter pipe 5, the communication between the air outlet hole 6 and the exhaust pipe 4 can be closed. Figure 1 , Figure 5As shown, when the baffle valve 8 moves to the right side of the outlet 6, it blocks the communication channel between the exhaust pipe 4 and the outlet, and the distillate in the distillation column cannot be discharged. When the baffle valve 8 moves to the left side of the outlet 6, so that the outlet 6 is connected to the exhaust pipe 4, the gas in the distillation column can enter the adsorption dilution device 7 through the outlet 6.

[0043] At the other end of the transfer tube 5 (such as...) Figure 5 The left end of the transfer pipe 5 is provided with an end plate 9, and a receiving pipe 10 is connected to the left side of the end plate 9. The right end of the receiving pipe 10 is connected to the end plate 9. The other end of the receiving pipe 10 is closed. An elastic element 11 is provided inside the receiving pipe 10 to provide axial thrust to the barrier valve 8. Figure 1 , Figure 5 In the normal non-working state, the leftward thrust of the elastic element 11 pushes the baffle valve 8 to the right of the outlet 6, and the exhaust pipe 4 is blocked from the outlet. During the distillation process, when the gas pressure in the distillation column 1 is too high, the gas in the exhaust pipe 4 pushes the baffle valve to the left, and the elastic element 11 is compressed and deformed until the outlet 6 is connected to the exhaust pipe. The gas enters the adsorption and dilution device 7 through the outlet 6, and the gas pressure in the distillation column decreases to ensure safety. When the gas pressure in the distillation column decreases, the gas is insufficient to push the elastic element 11, and the elastic element 11 pushes the baffle valve back to its original position to prevent the gas from continuing to be discharged, thus ensuring the gas pressure in the distillation column and ensuring the distillation effect.

[0044] To ensure reliable and stable movement of the partition valve 8, a slide rod 12 is connected to the side of the partition valve 8 away from the exhaust pipe 4, i.e. Figure 5 As shown, a sliding rod 12 is connected to the left side of the barrier valve 8. A through hole is provided on the end plate 9, through which the sliding rod 12 movably passes through the end plate 9 and extends into the receiving tube 10, connecting with the elastic element 11. The elastic element 11 can drive the sliding rod 12 to push the barrier valve 8 to move, and the sliding rod 12 can slide within the receiving tube 10. Specifically, on the end of the sliding rod 12 near the barrier valve 8 (i.e.... Figure 5 A connecting plate 13 is fixedly provided at the right end of the sliding rod 12 (that is, the right end of the elastic element 11). The elastic element 11 is connected to the connecting plate 13, thereby pushing the sliding rod 12 to move through the connecting plate 13. The other end of the elastic element 11 is fixedly connected to the closed end of the receiving tube 10. In order to enable the sliding rod 12 to move stably, a sleeve 14 is connected to the closed end of the receiving tube 10. The diameter of the sleeve 14 is larger than the diameter of the sliding rod 12, and the sliding rod 12 can slide into the sleeve 14.

[0045] In this embodiment, the elastic element 11 is a spring, which is sleeved around the sleeve 14, with one end fixedly connected to the closed end and the other end fixedly connected to the connecting plate.

[0046] Specifically, the adapter pipe 5 includes a valve pipe 51 and a transition pipe 52 connected to the valve pipe 51 at one end and to the exhaust pipe 4 at the other end. The inner diameter of the valve pipe 51 is greater than the outer diameter of the transition pipe 52; the diameter of the blocking valve 8 is greater than the inner diameter of the transition pipe 52 and less than the outer diameter of the transition pipe 52, and matches the inner diameter of the valve pipe 51. In this way, it is ensured that the blocking valve 8 can move smoothly in the valve pipe 51, that the blocking valve 8 can tightly fit the left end radial end face of the transition pipe 52, and that the communication between the exhaust pipe 4 and the gas outlet hole 6 is blocked.

[0047] In actual application, in order to avoid excessive movement of the blocking valve 8 to the left, the right side of the end plate 9 is provided with a communication pipe 15 through which the slide rod 12 moves, the diameter of the communication pipe 15 is greater than the diameter of the through hole, and the right end of the slide rod 12 is a slide column 31 matching the diameter of the communication pipe 15, the diameter of the slide column is greater than the diameter of the through hole.

[0048] The bottom of the distillation tower 1 is provided with a storage tank 16, and the sidewall of the storage tank 16 is provided with a first heating component 17; the sidewall of the distillation tower 1 is provided with a second heating component 18. The top of the distillation tower 1 is connected to the input end of the condensing device 2 through a first collection pipe 19, and the output end of the condensing device 2 is connected to the alcohol recovery device 3 through a second collection pipe 20; the top of the distillation tower 1 is connected to the output end through a reflux pipe 21. The reflux pipe 21 is connected to the output end through a reflux pump 22.

[0049] In combination Figure 3 As shown, the adsorption and dilution device includes a water tank 28, and two adsorption plates 29 are fixedly connected to the inner side upper portion of the water tank 28. When the excess steam enters the inside of the water tank 28 from the gas outlet hole 6, the adsorption plates 29 can effectively adsorb the odor substances, a small amount of impurities, and organic volatile substances in the alcohol steam, etc. The inside of the water tank 28 is fixedly connected with a water storage box 30, the steam from the distillation tower can fully contact with the water in the water storage box 30 and be diluted, and the discharge reduces the pollution of the environment. The side of the water tank away from the distillation tower 3 is fixedly connected with a water inlet pipe 23.

[0050] The second heating component 18 is a heating wire fixedly connected to the inside of the distillation tower 1, and the heating wires in the inside of the distillation tower are uniformly distributed in the bottom and the sidewall of the distillation tower. The heating wires adopt the principle of resistance heating, convert electric energy into heat energy, and adjust the temperature in the distillation tower by accurately controlling the current size of the heating wires to adapt to the distillation requirements of alcohol solutions with different concentrations. The first heating component 19 in the storage tank 16 is mainly used for secondary heating or preheating of the alcohol in the storage tank 16. The first heating component 19 can adopt an electric heating plate or other forms of heating elements, thereby improving the recovery rate of alcohol.

[0051] Storage tank 16 is connected to a delivery pipe 32 for alcohol. After the alcohol enters, the top is blocked to seal it. A reflux assembly for providing reflux force is fixedly connected to the top of the distillation column. The reflux assembly includes a reflux pipe 21, one side of which is fixedly connected to the inside of the distillation column. This effectively improves the purity of the alcohol and the recovery rate of the distillation. Through continuous circulation, the alcohol is better separated from other impurities. The other end of the reflux pipe 21 is connected to a reflux pump 22 and the inside of a protective shell 26 that connects to a condenser. This ensures that the refluxed alcohol vapor or liquid is evenly distributed within the protective shell 26, where it exchanges heat with the condenser 27 again or participates in other physicochemical changes during the distillation process. The two ends of the condenser extend out of the protective shell and are connected to an external refrigeration unit. The principle of the condenser is not described in detail here. The left side of the protective shell 26 is connected to a second collection pipe 20, which is connected to an alcohol recovery device 3 for collecting the final alcohol product. The storage tank, adsorption dilution device, and alcohol recovery device are all fixed on the base 25. The protective shell of the condensation device is fixed on the top of the support column 24, and the bottom of the support column 24 is fixed on the base 25.

[0052] The working principle of the high-efficiency condensation and recovery equipment for alcohol distillation described in this embodiment is as follows:

[0053] Heating wires evenly distributed within the distillation column heat the liquid mixture into vapor through precise temperature control, completing the initial distillation separation process. The generated vapor enters the protective shell through the first collection pipe 19 and flows into the adsorption and dilution device through the outlet. The gas flow rate is regulated by an elastic element in conjunction with a baffle valve, automatically opening and closing the outlet channel based on changes in vapor pressure to ensure safe gas flow control. When the pressure within the distillation column returns to normal, the spring force pushes the baffle valve back to its original position, closing the connection between the outlet and the exhaust pipe. The reflux pipe allows a portion of the vapor to be returned to the distillation column for secondary distillation, further improving the purity and recovery rate of the alcohol. Through continuous circulation, the separation effect between alcohol and impurities is significantly enhanced, achieving highly efficient alcohol distillation and recovery.

[0054] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that, based on the technical solutions disclosed in the present utility model, all modifications or variations that can be made by those skilled in the art without creative effort should be included within the scope of protection of the present utility model.
