However, due to the long reaction process route, a large number of reaction devices are required, resulting in a complex structure and layout of the multi-stage distillation unit. This requires a large space for the equipment and hinders flexible equipment placement. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] This utility model provides a multi-stage alcohol distillation apparatus, such as... Figures 1-6 As shown, the multi-stage alcohol distillation apparatus includes:

[0033] The unit includes a condensation unit and a distillation unit, with the condensation unit arranged between the distillation units. The condensation unit consists of four sets of condensers: a first condenser 201, a second condenser 202, a third condenser 203, and a fourth condenser 204. The first condenser 201, the second condenser 202, the third condenser 203, and the fourth condenser 204 are arranged vertically from top to bottom.

[0034] The distillation unit includes a first evaporator 110, a second evaporator 120, a third evaporator 130, and a fourth evaporator 140;

[0035] The top of the first evaporator 110 has a discharge port that connects to the material inlet of the first condenser 201. The material outlet of the first condenser 201 is connected to the side wall of the second evaporator 120 with a feed inlet. The top of the second evaporator 120 has a discharge port that connects to the material inlet of the second condenser 202. The material outlet of the second condenser 202 is connected to the side wall of the third evaporator 130 with a feed inlet. The top of the third evaporator 130 has a discharge port that connects to the material inlet of the third condenser 203. The material outlet of the third condenser 203 is connected to the side wall of the fourth evaporator 140 with a feed inlet. The top of the fourth evaporator 140 has a discharge port that connects to the material inlet of the fourth condenser 204.

[0036] The material first enters through the feed port on the side wall of the first evaporator 110. After primary distillation inside the first evaporator 110, it exits from the top of the first evaporator 110. After being condensed by the first condenser 201, it reaches the second evaporator 120 for further distillation. Subsequently, the vapor in the second evaporator 120 exits from the discharge port at the top of the second evaporator 120. After being condensed again by the second condenser 202, it reaches the third evaporator 130. In the third evaporator 130, tertiary distillation is carried out to generate vapor, which is then condensed by the third condenser 203 and reaches the fourth evaporator 140. Finally, after quaternary distillation, the vapor passes through the fourth condenser 204 to complete the multi-stage distillation and purify the alcohol.

[0037] The condensers are connected in series through pipes between the first evaporator 110, the second evaporator 120, the third evaporator 130 and the fourth evaporator 140, and the flow direction of the material in the adjacent condensers is opposite.

[0038] The material flow direction is the same in the first condenser 201 and the third condenser 203, and the material flow direction is the same in the second condenser 202 and the fourth condenser 204. The first evaporator 110 and the fourth evaporator 140 are arranged on one side of the condensation unit, and the second evaporator 120 and the third evaporator 130 are arranged on the other side of the condensation unit. The first evaporator 110 and the second evaporator 120 are arranged diagonally, and the third evaporator 130 and the fourth evaporator 140 are arranged diagonally.

[0039] This application utilizes a stacked design of four condensers in the condensation unit, along with alternating arrangements of the first, second, third, and fourth evaporators, to rationally plan the floor space of the multi-stage alcohol distillation unit by taking advantage of the principle of material reciprocating motion. This rational planning method reduces the space occupied by the multi-stage alcohol distillation unit in the workshop.

[0040] In a preferred embodiment of this invention, the condensation unit includes a main condensation pipe and a secondary condensation pipe 302; the main condensation pipe includes a first condenser pipe 3011, a second condenser pipe 3012, a third condenser pipe 3013, and a fourth condenser pipe 3014;

[0041] The first condenser tube 3011 is connected to the coolant inlet of the first condenser 201, the second condenser tube 3012 is connected between the coolant outlet of the first condenser 201 and the coolant inlet of the second condenser 202, the third condenser tube 3013 is connected between the coolant outlet of the second condenser 202 and the coolant inlet of the third condenser 203, and the fourth condenser tube 3014 is connected between the coolant outlet of the third condenser 203 and the coolant inlet of the fourth condenser 204.

[0042] The condensation unit also includes a secondary condensation main pipe 302, which is provided with several sets of branch pipes. The secondary condensation main pipe 302 is connected to the second condensation pipe 3012, the third condensation pipe 3013 and the fourth condensation pipe 3014 through the branch pipes.

[0043] In this embodiment, the coolant in the main condenser pipe sequentially cools the first condenser 201, the second condenser 202, the third condenser 203, and the fourth condenser 204, making full use of the coolant and reducing pipeline layout by means of the stacked condenser units. At the same time, the auxiliary condenser pipe 302 replenishes the second condenser pipe 3012, the third condenser pipe 3013, and the fourth condenser pipe 3014 with new coolant to meet the subsequent condensation needs.
