The bottom of the evaporation tank 2 is connected to the side wall of the extraction tank 1 through a connecting pipe 5. The connecting pipe 5 is detachably connected to the extraction tank 1. The top of the evaporation tank 2 is connected to the cooling tank 3 through an exhaust pipe 6. A defoamer 7 is provided on the exhaust pipe 6. The setting of the defoamer 7 can prevent foam from being generated during the evaporation of alcohol due to condensation. A cavity 8 is provided inside the cooling tank 3. A spiral guide plate 9 is provided inside the cavity 8. One side of the upper part of the cooling tank 3 communicates with a water outlet 10, and one side of the lower part communicates with a water inlet 11. A first thermometer 12 for monitoring the temperature inside is provided on one side of the outer wall of the cooling tank 3. When the temperature inside the cooling tank 3 rises after a long time of cooling, it can be monitored by the set first thermometer 12 and then feedback and control in time to make cooling water enter the cavity 8 from the water inlet 11 for replacement of the cooling water to realize the cooling tank 3, which can improve the cooling speed of the alcohol vapor. The bottom of the cooling tank 3 is connected to a collection tank 13. The bottom of the collection tank 13 communicates with a liquid discharge port 14.

[0021] A vacuum pump 15 is connected to the exhaust pipe 6 between the evaporation tank 2 and the defoamer 7. The design of the vacuum pump 15 can accelerate the speed of the alcohol vapor entering the cooling tank 3, increase the amount of the alcohol vapor entering, and further improve the alcohol recovery efficiency.

[0022] Preferably, the cooling tank 3 is of an inverted conical structure with a large upper end and a small lower end.

[0023] Several layers of cooling coils 16 are provided in the cooling tank 3 from top to bottom, and the cooling coils 16 are alternately arranged in pairs. The two ends of each cooling coil 16 are respectively connected to the cavity 8 on the opposite sides of the cooling tank 3, which can enable the alcohol vapor to directly contact the cooling and quickly form alcohol liquid and overflow into the collection tank, further improving the alcohol recovery efficiency.

[0024] One end of the air inlet pipe 4 connected to the extraction tank 1 is of a conical pipe structure, and several layers of gas-liquid separation meshes 17 are arranged at intervals inside the conical structure, which can block large-particle steam as much as possible and form water droplets that fall into the extraction tank 1 for secondary heating and evaporation, effectively accelerating the discharge speed of alcohol steam in the evaporation tank 2.

[0025] Preferably, a first exhaust valve 18 is provided on one side of the top of the cooling tank 3 and on one side of the top of the collection tank 13.

[0028] Working principle:

[0029] The extraction liquid containing alcohol is heated in the extraction tank 1. When the temperature formed by heating reaches a certain level, a mixture of water vapor and alcohol steam will be formed and enter the evaporation tank 2 through the air inlet pipe 4. When passing through several layers of gas-liquid separation meshes 17 before entering the evaporation tank 2, the large-particle steam will be retained on the separation meshes and drip downward into the extraction tank 1 for secondary heating and evaporation. After the water vapor and alcohol steam enter the evaporation tank 2 and are separated, the liquid part thereof enters the extraction tank 1 again through the connecting pipe 5 for heating, and its alcohol steam enters the cooling tank 3 through the exhaust pipe 6. Before the alcohol steam enters the cooling tank 3, the vacuum pump 15 can accelerate its passing speed and passing amount, and eliminate the foam generated by the condensation of alcohol during evaporation when passing through the defoamer 7. When the alcohol steam enters the cooling tank 3, it forms alcohol liquid after cooling and finally enters the collection tank 13.
