Description

Technical Field

[0001] This utility model specifically relates to an energy-saving and consumption-reducing distillation device, belonging to the technical field of distillation equipment. Background Technology

[0002] Distillation is a separation process that separates components in a mixture based on their different volatility. It is widely used in industries such as chemical, petroleum, and pharmaceutical. However, traditional distillation equipment often suffers from problems such as high energy consumption and low separation efficiency.

[0003] Traditional distillation columns typically require a continuous supply of a large amount of heat energy to the reboiler, while the overhead condenser consumes a large amount of cooling water to condense the overhead vapor, resulting in a huge waste of energy. Moreover, the gas-liquid contact inside some traditional devices is insufficient, leading to poor separation effect and requiring multiple distillations to achieve the expected purity, which further increases energy consumption and production costs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing an energy-saving and consumption-reducing distillation apparatus, including a distillation column body. A distillation assembly is installed on the outer surface of the distillation column body. The distillation assembly includes a reboiler body and a mounting plate. The reboiler body is installed at the bottom of the distillation column body. The mounting plate is installed on the outer surface of the distillation column body. A reboiler body is installed on the outer surface of the mounting plate. The output end of the reboiler body is connected to the outer surface of the distillation column body. The input end of the reboiler body is connected to a connecting pipe, and the output end of the connecting pipe is connected to the reboiler body.

[0005] Furthermore, a condenser body is provided above the mounting plate. The input end of the condenser body is connected to a fixed pipe, and the other end of the fixed pipe is connected to the upper surface of the distillation column body. Two reflux pipes are installed at the output end of the condenser body, and the output end of one of the reflux pipes is connected to the upper surface of the distillation column body.

[0006] Furthermore, a second heat exchanger and a first heat exchanger are respectively installed on the outer surfaces of the return pipe and the connecting pipe, and a circulation pipe connects the first heat exchanger and the second heat exchanger.

[0007] Furthermore, a circulation pump is installed on the surface of the circulation pipe.

[0008] Furthermore, the distillation assembly also includes a tray installed inside the distillation column body, and the upper surface of the tray is provided with sieve holes.

[0009] Furthermore, the distillation assembly also includes a bubble cap plate installed inside the distillation column body.

[0010] Beneficial effects:

[0011] By coordinating the distillation column body with the distillation components, the waste heat of the steam in the distillation column body can be recovered and used to preheat the liquid in the bottom of the column, which greatly reduces the heating energy consumption of the reboiler body and the cooling energy consumption of the condenser body, thus achieving the goal of energy saving and consumption reduction.

[0012] By combining the trays, sieves, and bubble caps, the gas-liquid contact area and contact time are increased, improving separation efficiency, reducing the number of distillation cycles, and further reducing energy consumption and production costs. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 As shown, an energy-saving and consumption-reducing distillation device includes a distillation column body 1. The distillation column body 1 is configured to store the mixture, thereby facilitating subsequent distillation of the mixture.

[0019] The outer surface of the distillation column body 1 is equipped with a distillation assembly 2, which includes a column bottom body 201 and a mounting plate 202. The column bottom body 201 is installed at the bottom of the distillation column body 1. The column bottom body 201 is mainly used for separation operations, especially when different components in the feed have different boiling points.

[0020] Mounting plate 202 is installed on the outer surface of the distillation column body 1. Reboiler body 203 is installed on the outer surface of mounting plate 202. Reboiler body 203 is an auxiliary heating device set in the stripping section during distillation operation. It is mainly used to improve the irreversibility of the separation process and reduce energy consumption costs by using a heat source with a lower grade than the bottom reboiler.

[0021] The output end of the reboiler body 203 is connected to the outer surface of the distillation column body 1. The input end of the reboiler body 203 is connected to the connecting pipe 204, and the output end of the connecting pipe 204 is connected to the column bottom body 201. The liquid in the column bottom body 201 is heated and vaporized, so that it re-enters the distillation column body 1 to participate in the separation process.

[0022] The input end of the condenser body 205 is connected to a fixed pipe 206, and the other end of the fixed pipe 206 is connected to the upper surface of the distillation column body 1. The output end of the condenser body 205 is equipped with two reflux pipes 207, one of which is connected to the upper surface of the distillation column body 1. The condenser body 205 is a type of heat exchanger that can convert gas or vapor into liquid and transfer the heat in the pipes to the air near the pipes in a fast manner. The condenser operation is an exothermic process, so the condenser temperature is relatively high.

[0023] The outer surfaces of the return pipe 207 and the connecting pipe 204 are respectively equipped with a second heat exchanger 209 and a first heat exchanger 208, and a circulation pipe 210 connects the first heat exchanger 208 and the second heat exchanger 209. The first heat exchanger 208 and the second heat exchanger 209 are energy-saving devices that realize heat transfer between materials between two or more fluids at different temperatures. They transfer heat from the fluid with a higher temperature to the fluid with a lower temperature, so that the fluid temperature reaches the index specified by the process to meet the needs of the process conditions.

[0024] A circulation pump 211 is installed on the surface of the circulation pipe 210. The distillation assembly 2 also includes a tray 212 installed inside the distillation column body 1. The upper surface of the tray 212 is provided with sieve holes 213. The distillation assembly 2 also includes a bubble cap plate 214 installed inside the distillation column body 1. The bubble cap plate 214 can make the rising vapor fully contact the liquid on the tray 212, increase the gas-liquid contact area and contact time, and improve the separation efficiency.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
