Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of distillation, in particular to a distillation device. BACKGROUND

[0002] Distillation is a common extraction method, which can be used not only to extract some components in a mixture, but also to extract some effective components in a plant. Taking the extraction process of rose hydrolat as an example, the rose is placed in a distillation kettle containing water during the extraction process, and then some components in the rose are dissolved or dispersed in water at high temperature by heating the distillation kettle (or introducing high-temperature steam into the solution), and are overflowed with water vapor. The overflowed water vapor enters a condensing device to be condensed into a liquid (an oil-water mixture) and is collected. The oil-water mixture is separated, purified, concentrated, and the like to obtain a related product.

[0003] During distillation, especially condensation, oil (an organic matter to be extracted) and water will be liquefied when they contact the condensing device, and part of the organic matter will adhere to the condensing device. After a long time, a large amount of the organic matter will adhere to the condensing device, which will not only seriously affect the efficiency of the condensing device, but also seriously deteriorate the part of the organic matter, which cannot be used and will affect the quality of the subsequent extract. The common method is to clean the condensing device separately after stopping the machine, which will affect the production efficiency to some extent. SUMMARY

[0004] The present application aims to provide a distillation device which can automatically and in real time clean the condensing device on the basis of ensuring the condensing efficiency without affecting the production process.

[0005] The embodiment of the present application is implemented by the following technical solutions: the distillation device of the present application comprises a heating device and a condensing device which are in communication with each other; the condensing device comprises a plurality of hollow condensing plates which are distributed in a circular ring shape, a liquid discharge pipe which is in communication with the condensing plates, a communication pipe which is used to communicate adjacent condensing plates, and a plurality of steam guide pipes which are in communication with the exhaust port of the heating device; a cooling assembly is arranged in one of the condensing plates, and a valve is arranged in one of the steam guide pipes; a communication port is formed in the side wall of the communication pipe, and one of the steam guide pipes is connected to one of the communication ports; an L-shaped flow guide plate is arranged on the inner wall of the communication pipe, and the flow guide plate is arranged close to the communication port.

[0006] Further, the cooling assembly comprises a plurality of condensing pipes, and a circulating water device which is in communication with the condensing pipes.

[0007] Further, the cooling assembly further comprises a water drainage tank arranged above the condensing plate, a water drainage pipe in communication with the water drainage tank, and a water inlet pipe arranged in the condensing pipe; the upper end of the condensing pipe is arranged in the water drainage tank after penetrating through the condensing plate; one end of the water inlet pipe is arranged close to the bottom of the condensing pipe, and the other end of the water inlet pipe is connected with the circulating water device after penetrating through the water drainage tank; the water drainage pipe is connected with the circulating water device.

[0008] Further, the condensing pipe is arranged in an inclined manner.

[0009] Further, the outer wall of the condensing plate is provided with a cooling fin.

[0010] Further, the heating device comprises a heating tank and a feeding port arranged on the side wall of the heating tank; the heating tank is arranged below the condensing device.

[0011] Further, the inner wall of the condensing plate is coated with polytetrafluoroethylene.

[0012] Further, the valve is an electromagnetic valve or a pneumatic valve.

[0013] The technical scheme of the embodiment of the present application has at least the following advantages and beneficial effects: when the distillation device is used, the raw material is placed in the heating device for high-temperature heating, and the extract evaporates together with the water vapor and enters the condensing device for condensation. The high-temperature water vapor enters the communication pipe through the steam guide pipe and the communication port, and due to the L-shaped flow guide plate arranged at the communication port and the small gap between the flow guide plate and the communication pipe, the high-temperature steam enters the communication pipe and is sprayed in the direction of one of the condensing plates under the action of the flow guide plate. At this time, the cooling assembly in the condensing plate is rapidly washed by the high-temperature steam, which can wash off the grease adhered to the surface of the cooling assembly. When the water vapor passes through the condensing plate, it will not be affected by the flow guide plate when it enters the next communication pipe, so the flow rate of the water vapor is reduced at this time, which can well contact the subsequent cooling assembly and perform condensation operation. And since the entire condensing device is in a circular ring structure, it can accommodate a large amount of water vapor. In addition, only one valve is in an open state at the same time (the remaining valves are closed), so the cleaning operation of one cooling assembly in one condensing device can be performed at the same time. By periodically opening different valves, periodic cleaning of different cooling assemblies can be realized. Ensure that all cooling assemblies can maintain a high-efficiency working state, which can significantly reduce the frequency of manual cleaning and maintenance. BRIEF DESCRIPTION OF DRAWINGS

[0029] Embodiments

[0030] The following is further illustrated in conjunction with specific embodiments, such as the accompanying drawings Figure 1 - the accompanying drawings Figure 8As shown, the distillation apparatus of this embodiment includes a heating device and a condensing device that are interconnected. The condensing device includes multiple hollow condensing plates 11 arranged in a ring shape, a drain pipe 18 communicating with the condensing plates 11, a connecting pipe 12 for connecting adjacent condensing plates 11, and multiple steam conduits 15 communicating with the exhaust ports of the heating device. A cooling component is provided inside each condensing plate 11, and a valve 16 is provided in each steam conduit 15. A connecting port 13 is opened on the side wall of the connecting pipe 12, and a steam conduit 15 is connected to a connecting port 13. An L-shaped guide plate 14 is provided on the inner wall of the connecting pipe 12, and the guide plate 14 is disposed close to the connecting port 13. Specifically, in use, the raw material is placed in the heating device for high-temperature heating, wherein the extract evaporates along with water vapor and enters the condensing device for condensation (the condensed liquid is discharged through the drain pipe 18). High-temperature steam enters the connecting pipe 12 after passing through the steam conduit 15 and the connecting port 13. Because an L-shaped guide plate 14 is provided at the connecting port 13, and the gap between the guide plate 14 and the connecting pipe 12 is small (as shown in the attached diagram)... Figure 8 As shown, high-temperature steam enters the connecting pipe 12 and, under the action of the guide plate 14, is sprayed towards one of the condensing plates 11. At this time, the cooling components in the condensing plate 11 are rapidly washed away by the high-temperature steam, removing grease adhering to their surfaces (since the cleaning process is performed in real time, it does not affect the distillation process at all, and the washed-off grease can still be used). After passing through the condensing plate 11, the steam entering the next connecting pipe 12 is not affected by the guide plate 14, thus reducing the steam velocity and allowing for better contact with subsequent cooling components for condensation. Furthermore, because the entire condensing device has a circulating ring structure, it can accommodate a large amount of steam. In addition, only one valve 16 is open at a time (the rest are closed), allowing for the cleaning of one cooling component in one condensing device simultaneously. By periodically opening different valves 16, periodic cleaning of different cooling components can be achieved. This ensures that all cooling components maintain efficient operation and significantly reduces the frequency of manual cleaning and maintenance.

[0031] The cooling assembly in the embodiment comprises a plurality of condensing tubes 22 and a circulating water device communicating with the condensing tubes 22. The cooling assembly further comprises a drain tank 21 arranged above the condensing plate 11, a drain pipe 24 communicating with the inside of the drain tank 21, and a water inlet pipe 23 arranged in the condensing tube 22; the upper end of the condensing tube 22 penetrates through the condensing plate 11 and is arranged in the inside of the drain tank 21; one end of the water inlet pipe 23 is arranged close to the bottom of the condensing tube 22, and the other end penetrates through the drain tank 21 and is connected with the circulating water device; the drain pipe 24 is connected with the circulating water device. Specifically, the circulating water device sends cooling water to the bottom of the condensing tube 22 through the water inlet pipe 23, the cooling water flows upward from the bottom of the condensing tube 22 and flows into the drain tank 21, and finally returns to the circulating water device through the drain pipe 24 connected with the drain tank 21.

[0032] The condensing tube 22 in the embodiment is arranged obliquely. Specifically, this can better wash off the oil adhered to the condensing tube 22.

[0033] The outer side wall of the condensing plate 11 in the embodiment is provided with a cooling fin 17.

[0034] The heating device in the embodiment comprises a heating tank 31 and a feeding port arranged on the side wall of the heating tank 31; the heating tank 31 is arranged below the condensing device.

[0035] The inner wall of the condensing plate 11 in the embodiment is coated with polytetrafluoroethylene. Specifically, coating the inner wall of the condensing plate 11 with polytetrafluoroethylene (or other oil-repellent materials) can effectively avoid oil adhesion. However, coating the condensing tube 22 with oil-repellent materials will seriously reduce the condensing effect. Therefore, the condensing tube 22 still needs to use a material with high thermal conductivity.

[0036] The valve 16 in the embodiment is an electromagnetic valve or a pneumatic valve. Specifically, in addition to the process of opening only one valve 16 at a time, all the valves 16 can also be opened, and only one valve 16 is opened only when the condensing tube 22 needs to be cleaned. Specifically, the setting can be made according to the adhesion strength of the extract.

[0037] In summary, the distillation device of the present embodiment uses the heating device to heat the raw material at high temperature, and the extract evaporates with the water vapor and enters the condensing device to be condensed. The high-temperature water vapor enters the communication pipe 12 through the steam guide pipe 15 and the communication port 13. Since the L-shaped flow guide plate 14 is arranged at the communication port 13, and the gap between the flow guide plate 14 and the communication pipe 12 is small, the high-temperature steam entering the communication pipe 12 is sprayed in the direction of one of the condensing plates 11 under the action of the flow guide plate 14. At this time, the cooling components in the condensing plate 11 are quickly washed by the high-temperature steam, which can remove the oil adhering to the surface of the cooling components. After the water vapor passes through the condensing plate 11, it enters the next communication pipe 12 and is not affected by the flow guide plate 14. Therefore, the flow rate of the water vapor is reduced at this time, which can be in good contact with the subsequent cooling components and perform condensation operation. Since the entire condensing device is in a circular ring structure, it can accommodate a large amount of water vapor. In addition, only one valve 16 is open at the same time (the rest are closed), so the cleaning operation of one cooling component in one condensing device can be performed at the same time. By periodically opening different valves 16, periodic cleaning of different cooling components can be achieved. This ensures that all cooling components can maintain high-efficiency working state, which can significantly reduce the frequency of manual cleaning and maintenance.

[0038] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
