Description

[Detailed Description of the Invention] The present invention relates to a distillation apparatus, and more specifically, to a distillation apparatus in which a droplet entrainment prevention section is disposed between a steam generator such as a boiler and a condenser. It is something.

Generally, in distillation equipment, in order to obtain high-purity distilled water, a type of droplet prevention part called a baffle plate is installed between a steam generator such as a boiler and a condenser. The droplet entrainment prevention unit removes droplets by meandering the steam path from the steam generator to the condenser, or by appropriately arranging plate-like members or rod-like members in the path. It is. However, in the past, it has not been possible to reliably prevent entrainment of droplets, and this has not been fully satisfactory.

The present invention was created in view of the conventional problems mentioned above.The entrainment prevention part installed in the steam path from the steam generator to the condenser has a triple structure, and the inner cylinder connected to the condenser is used to prevent condensation. In addition, the lower end of the inner cylinder is placed below the position of the communication port provided in the intermediate cylinder to prevent entrainment of droplets. This is to make it more reliable.

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 1 shows a front sectional view of a distillation apparatus according to the present invention. The distillation apparatus includes a boiler 1 as an example of a steam generator, and a condenser 3 for condensing the steam from the boiler 1, and a droplet entrainment prevention part 5 is provided between the boiler 1 and the condenser 3. It is something that The boiler 1 includes a raw water supply port 1A for supplying raw water, and a heater attachment port 1B for attaching a suitable heater. This boiler 1 uses a heater to heat raw water supplied into the interior from a raw water supply port 1A to generate steam, and the generated steam is discharged through a discharge port 1C provided at the top.
It is something that rises and is discharged from.

The condenser 3 receives and condenses steam from the boiler 1, and has a cylindrical shape, with a steam inlet 3A provided at one end and a distilled water outlet at the other end. A distilled water outlet 3B is provided. Further, inside the cylindrical condenser 3, a cooling pipe 7 through which cooling water flows is installed in a spiral manner, and both ends of the cooling pipe 7 are provided with cooling water inlet/outlet ports 7A, 7.
B is provided.

As is clear from the figure, the splash entrainment prevention section 5 has a triple structure, and is connected to the outer cylinder 5A and the discharge port 1C for discharging steam from the boiler 1. . An inner cylinder 5B on the inside of the droplet entrainment prevention section 5 is integrally connected to the steam inlet 3A of the condenser 3. The outer cylinder 5
Between A and the inner cylinder 5B, there is disposed an intermediate cylinder 3C which blocks the boiler 1 and the condenser 3 from being in full communication with each other. This intermediate cylinder 5C is the outer cylinder 5
A, it is integrally connected to the inner cylinder 5B and forms a dew condensation chamber 5D. As shown in FIG. 2, the intermediate cylinder 5C is formed with a plurality of communication ports 5E that open in a substantially tangential direction of the inner cylinder 5B, and the bottom thereof is provided with a plurality of communication ports 5E as shown in FIG. As shown, the outlet 5F is formed diagonally downward. Said inner cylinder 5B
The condensation chamber 5D is surrounded by the intermediate cylinder 5C and extends into the condensation chamber 5D, and its lower end extends below the communication port 5E at the lowest position. be.

In the above configuration, steam generated by heating raw water in the boiler 1, which is an example of a steam generator, reaches the outer cylinder 5A of the droplet entrainment prevention part 5 from the exhaust port 1C of the boiler 1. , is ejected into the condensation chamber 5D from the communication port 5E formed in the intermediate cylinder 5C. The communication port 5E is connected to the inner cylinder 5.
Since it is opened almost in the tangential direction of B,
The steam ejected into the dew condensation chamber 5D comes into contact with the circumferential surface of the inner cylinder 5B and is rotated, descending toward the lower end of the inner cylinder 5B. Then, it passes through the inner cylinder 5 and flows into the condenser 3,
Condensed in the condenser 3, the distilled water is discharged from the outlet 3B.
It is obtained as distilled water from

By the way, as mentioned above, the communication port 5 of the intermediate cylinder 5C
Steam is ejected from the condensation chamber 5D from the inner cylinder 5.
When it comes into contact with the circumferential surface of B, excess steam such as droplets in the steam will condense and drip. At this time, since the steam descends while swirling, the dripping of water droplets condensed on the outer peripheral surface of the inner cylinder 5B, the inner peripheral surface of the intermediate cylinder 5C, etc. is promoted. Therefore,
Steam and water separation is reliably and effectively carried out in this part, and high-quality steam flows into the condenser 3, resulting in high-purity distilled water. Note that the water droplets dropped in the condensation chamber 5D flow down into the boiler 1 from the water outlet 5F at the bottom.

As can be understood from the above description of the embodiments, the gist of this invention is the configuration as described in the claims of the utility model registration, so the steam ejected into the interior from the communication port of the intermediate cylinder is It comes into contact with the cylinder and descends toward the lower end of the inner cylinder. Therefore, dew condensation is likely to occur on the outer circumferential surface of the inner cylinder, and the resulting water droplets are encouraged to drip, thereby ensuring reliable and effective separation of steam and water. Therefore, high-quality steam flows into the condenser, making it possible to obtain distilled water with higher purity.

Note that this invention is not limited to the above-mentioned embodiments, but can be implemented in other forms by making appropriate design changes.
For example, it is possible to have a triple structure or more if necessary.
