Description

[Detailed description of the invention] The present invention relates to a small-sized emergency water generation device, and is particularly a water generation device for obtaining drinking water in the event of a disaster or when it is difficult to obtain drinking water. This device incorporates a reverse osmosis membrane device made of hollow fibers and is equipped with a pump, making it compact and easy to handle.

For example, there are cases where it is difficult to obtain drinking water due to an earthquake disaster or a marine accident, and it is desirable to develop a simple bookbinding device.

In addition, various bookbinding devices have been proposed in the past, and some are in practical use, but the devices are large and inconvenient to transport, making it difficult to carry a compact and high-performance device. There wasn't.

Recently, research has been conducted into the desalination of seawater and brackish water using reverse osmosis, and permeable membrane modules that utilize hollow fiber membranes have attracted particular attention for their good performance, and the applicant has proposed various proposals for these modules. are doing.

This invention was arrived at as a result of various studies aimed at obtaining a simple freshwater generating device as described above using such a hollow fiber permeable membrane module. A suction section for water to be treated filled with filter material is provided in the cylinder, and the permeable membrane module device is enclosed in the upper chamber of the cylinder. A fluid pump device is provided at the top of the waist cylinder, and the water suction side vibrator is used to suck the water to be treated. The discharge side is connected to the treated water introduction side of the permeable membrane module device, and purified water that has permeated through the hollow fibers is taken out of the cylinder.

The present invention will be described in detail below based on the drawings, but the drawings show one example of a specific implementation, and the present invention is not limited to these illustrated examples.

FIG. 1 is a partially cutaway side view showing the configuration of the simple freshwater generating device of the present invention.

FIG. 3 is an explanatory diagram mainly showing the structure in a vertical cross section at the center of FIG. 1. FIG.

In these figures, the simple freshwater generating device of the present invention includes a pressure-resistant cylinder 1 made of metal or synthetic resin and with only the lower bottom open, and the open part screwed or fitted, or flanges formed with each other. The main body is formed of a lower cylindrical body 2 configured to be airtightly attached.

The lower cylindrical body 2 may be constructed as a cylindrical body with a bottom, but the figure shows a flange 3 provided with a base plate 4 attached thereto to match the outer periphery of the flange.

A permeable membrane module device, which will be described later, is enclosed in the cylindrical body 1 of the main body, and the lower cylindrical body 2 is provided with one or more raw water intake ports 2' on the peripheral wall, and the inside thereof is filled with a filter material 15. Ru.

The filter material 15 is a relatively coarse particle filter for removing impurities from raw water, and a net made of gold or copper is provided at the intake port 2' to prevent the filter material 15 from flying out.

- The above-described permeable membrane module device 10 is enclosed in the force cylinder 1, and the module device 10 includes a raw water intake side resin layer (upper resin layer) 20, a permeation side resin layer (lower resin layer) 1
9, and a perforated tube 2 is provided approximately in the center of the upper resin layer 20.
4 is opened and fixed.

A large number of hollow fibers 25 are formed around the perforated n24 in an inverted U shape.
Both ends of the hollow fibers 25 are embedded through the lower resin layer 19, and the hollow portions of the hollow fibers 25 are opened at the lower surface of the lower resin layer 19.

Therefore, the raw water that is forced in from the perforated cylinder 24 permeates through the semipermeable membrane formed of hollow fibers, and the permeated water passes through the hollow portion of the hollow fibers 25 and is taken out from the lower surface of the lower resin layer 19.

Note that these perforated tubes 24 may be water pipes or water guide columns of other shapes.

The module device 10 configured in this manner is formed as a single unit and is enclosed in a replaceable manner.

Then, when enclosing the module device 1, a snap ring or filter material is interposed on the inner circumferential surface of the cylindrical body 1, and the module device 1 is enclosed.
The peripheral portion of the hole 0 forms a cavity that communicates with the outlet 13 for the concentrated water that has not permeated.

Note that the discharge port 13 is provided with a valve for controlling the operating pressure of the module device.

Further, a double filter layer 22, 23 is provided on the upper part of the module device 10, and the module device 10 is placed via a snap ring 21. Below the lower waist resin layer 19, a space is formed to form a permeated water reservoir. A local portion 18 is formed.

It is recommended that the cavity 18 be configured as a filter tank filled with activated carbon.

Further, the hollow portion 18 is formed to be sealed by a dividing plate 16, and the dividing plate 16 is held by a snap ring 17.

Appropriate O-rings for sealing are provided on the circumferential surfaces of the upper and lower side fat layers 20 and 19 of the module device 10 and the circumferential surface of the dividing plate 16, so that the module device 10 is arranged in a watertight manner within the cylinder body 1. do.

Further, a suitable pump device 5 is provided at the top of the main body, and although the pump device 5 is shown as being constructed from a single cylinder in the figure, any suitable pump device known in the art may be used.

Generally, it is practical for these pump devices to be manual pumps, but if electric power can be easily obtained, it is preferable to use electric pumps or devices that can be used in combination with manual pumps.

In addition, these pump devices 5 need to be easily operated, and the illustrated example has a handle 8 for operation that is removable and can be held on the side of the main body when not in use. show.

Reference numeral 8' indicates a mooring device for the handle 8, and reference numeral 9 indicates a snap arresting device.

7 is a pump operating rod, and 6 is a fulcrum member.

A suction pipe 11 is provided on the suction side of the pump device 5 via a check valve, and the pipe 11 is connected to a cavity communicating with the raw water intake port 2' formed in the lower cylinder 2 at the lower part of the cylinder 1. Open at the end.

The discharge side of the pump device 5 also communicates with an intake port 1' provided at the top of the cylinder 1 through a suitable check valve.

A permeated water take-off hose 12 is connected to a hollow part of a permeated water reservoir formed in the lower part of the module device 10.

Note that 14 indicates a pressure gauge.

The fresh water generator constructed in this manner is placed in raw water as shown in FIG. It is force-fed into the bore tube 24.

Then, the permeated water that has permeated as described above is sent out from the take-out hose 12 through the cavity 18, and the concentrated water that has not permeated is discharged from the discharge port 13.

Since the simple water generation device of the present invention is constructed in this way, it is small and lightweight, and it is also simple.Since it uses a module device using a hollow fiber permeable membrane, it can generate water efficiently, especially for lifeboats, etc. It is extremely ideal for a permanent water production system.
