Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing dissolved oxygen-enriched water for producing water with an increased amount of dissolved oxygen.

[0002]

2. Description of the Related Art Generally, aeration is performed to increase the amount of dissolved oxygen in water for breeding fish such as tropical fish, live fish, and pond water, purify drinking water, and aerobically treat wastewater or sewage. Aeration) is taking place.

[0003] A commonly used aeration device comprises an air pump for supplying air, a tube for introducing the supplied air into water, and a diffuser attached to the tube (spray aeration device), or This is a natural fall aeration device consisting of an impeller or artificial waterfall that rotates on the surface of the water, forcing air bubbles into the water to increase the contact area between the water and air as much as possible, It is to dissolve.

[0004]

However, in the above-described conventional apparatus for producing dissolved oxygen-enriched water by aeration, when the outside air is brought into direct contact with water, the dust in the outside air is liable to be mixed with the water and thus is not suitable. It is sanitary, and the mixed sound of air and water in water or on the surface of the water sometimes causes noise, and it has not been possible to produce dissolved oxygen-enriched water sanitarily and without generating noise.

[0005] Further, such aeration treatment is usually performed by mixing air in a container filled with water or in a predetermined volume of still water, but such a method has a required concentration of dissolved oxygen. It has been difficult to produce water continuously and stably.

Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a device for producing dissolved oxygen-enriched water which can efficiently increase the oxygen concentration with a relatively simple structure, and which has low noise and hygiene. That is, an apparatus capable of producing dissolved oxygen-enriched water.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a ventilation pipe made of silicone rubber is accommodated in a water tank provided with a water supply port and a drain plug which communicates with a water supply device. Both ends of this ventilation pipe are projected outside the water passage container, and one end thereof is connected to a supply path from a supply device of an oxygen-containing gas. In the water passage tank, sea ash is extracted from a residue obtained by water extraction at pH 5 to 14. Thus, an apparatus for producing dissolved oxygen-enriched water filled with a powdery far-infrared radiator was obtained.

Alternatively, a silicone rubber vent pipe smaller than the inside diameter of the water pipe is passed between the outside of the vent pipe and the inside of the water pipe inside the silicone rubber water pipe connected to the water supply device. It is arranged so that a gap capable of water is formed, both ends of the ventilation pipe are projected outside the water pipe, and one end of the ventilation pipe is connected to a supply device of an oxygen-containing gas, and the water pipe has a pH of 5 to 5 for seaweed ash. The apparatus for producing dissolved oxygen-enriched water embedded in a powdery far-infrared radiator composed of the residue extracted with water in step 14 is provided.

In the apparatus for producing dissolved oxygen-enriched water having the above-mentioned structure, the oxygen-containing gas supply device is a pressurized pump, and a pressure regulating valve is attached to the other end of the ventilation pipe.

Further, the above-mentioned vent pipe is an apparatus for producing dissolved oxygen-enriched water having the above-described structure in which a plurality of silicone rubber pipes are collected in parallel.

An apparatus for producing dissolved oxygen-enriched water according to the present invention comprises:
A ventilation pipe made of silicone rubber is disposed inside the water pipe or the water tank, and an oxygen-containing gas such as air is supplied to the ventilation pipe, and water is supplied to the water pipe or the water tank. that time,
Oxygen dissolves in the water in the water pipe or water tank through the silicone rubber pipe wall that selectively allows oxygen to permeate easily, increasing the amount of dissolved oxygen in the water that passes or stays inside the water pipe or water tank. .

In the apparatus according to the present invention, since the oxygen-containing gas and the water pass through the ventilation pipe or the water pipe (or the water tank) without directly contacting each other, dust in the air in the production environment is generated. It can be prevented from being mixed with the treated water, and the dissolved oxygen-enriched water can be produced hygienically and continuously. Further, since water and air are not directly mixed, there is no mixing noise on the water surface or in water as in a conventional aeration apparatus, and it is possible to produce dissolved oxygen-enriched water with low noise.

Further, in the apparatus for producing dissolved oxygen-enriched water having the above-described structure, water passing through the water pipe (or water tank) is affected by a predetermined far-infrared radiator. That is,
The far-infrared radiator in the form of powder and granules composed of residues obtained by extracting seaweed ash with water at pH 5 to 14 uses seaweeds, which are considered to take in many kinds of elements from seawater, as raw materials. Is a far-infrared radiator whose emissivity and radiant intensity are considered to be ideally high even in a relatively wide wavelength range and at a low temperature of 17 to 40 ° C.

Therefore, when the apparatus is driven in a normal temperature environment, even if the raw water is at a temperature lower than the normal temperature, the raw water is heated relatively quickly while passing through the water pipe (or the water tank), Therefore, the gas permeation of the silicone rubber is also increased, and more oxygen is efficiently dissolved in water.

Further, if a pressurized pump is adopted as a supply device of the oxygen-containing gas, the pressurized oxygen-containing gas is supplied to the ventilation pipe, and a pressure regulating valve is attached to the other end of the ventilation pipe. And the dissolution rate of oxygen in water can be increased, so that the dissolved oxygen-enriched water can be produced more efficiently.

Further, in the invention in which the ventilation pipe is a collecting pipe in which a plurality of silicone rubber pipes are gathered in parallel, the oxygen-containing gas has a large area obtained by summing the surface areas of the plurality of silicone rubber pipes, and the oxygen-containing gas passes through the silicone rubber. As a result, the contact area between the water and the gas is increased as compared with a vent pipe composed of a single silicone rubber pipe, and the dissolved oxygen-enriched water can be produced more efficiently.

[0017]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, in the first embodiment, a water supply port 2 communicating with a water pipe (not shown) and a drain plug 3 with a built-in filter that can be opened and closed with a handle are provided in a cylindrical water tank 1 having an upper surface opening. , Silicone rubber vent tube 4

This is an apparatus A for producing dissolved oxygen-enriched water in which a powdery and granular far-infrared radiator 7 composed of a residue obtained by extracting ash with water at a pH of 5 to 14 is packed to a density that allows water permeation.

Here, the far-infrared radiator 7 in the form of a granular material is

In order to sufficiently increase the surface area, it is preferable that the powder has a particle size of about 200 mesh, but in order to increase the efficiency of water permeability, a powder having a particle size larger than this may be used.

By the way, the ventilation pipe 4 made of silicone rubber is used.
Is a polydimethylsiloxane (-
O-Si (CH ₃ ) _2- ) _n or a polydimethylsiloxane derivative is employed. As shown in Table 1 (excerpted from the Chemical Handbook, Applied Chemistry), poly (4-methylpentene-1) and poly (4-methylpentene-1) are used. It is much more excellent in oxygen permeability than a polymer membrane such as (2,6-dimethylphenylene oxide), and the gas permeability coefficient changes according to the temperature as shown in Table 2.

Incidentally, assuming that the wall of the ventilation pipe 4 made of silicone rubber is a non-porous membrane, the amount of gas permeating this is expressed by the following equation. Q = (P / l) (p ₁ −p ₂ ) At (where Q is a gas permeation amount, P is a gas permeation coefficient, p ₁ , p
₂ is the partial pressure of the gas supplied to the membrane and the partial pressure of the gas on the permeation side of the membrane, 1 is the film thickness, A is the permeation area, and t is the time. Therefore, when a silicone rubber vent tube is employed, the conditions for efficiently increasing the amount of dissolved oxygen are as follows: the wall thickness of the tube wall is made as thin as possible, the pressure in the vent tube is increased, and the vent tube is formed as long as possible. Is preferred.

The apparatus for producing dissolved oxygen-enriched water configured as described above supplies tap water from a water supply port 2 facing an upper opening of a water flow tank 1 and at the same time a required flow rate (flow rate) from an air pump 5. By supplying air, the handle of the drain plug 3 at the lower part of the water tank 1 can be opened and closed appropriately to take out the dissolved oxygen-enriched water.

As the oxygen-containing gas used in the present invention, air is usually employed, but in addition, a mixed gas artificially containing oxygen or pure oxygen may also be employed. In the above embodiment, a water pipe is used as a water supply device. However, a water supply device for groundwater or a well-known water supply device for supplying water previously stored in a container or the like may be used. The arrangement of the ventilation pipes 4 in the water tank 1 is not limited to a spiral shape along the inner peripheral surface, but is also arranged in a randomly bent state or in the longitudinal direction of a large number of ventilation pipes connected via manifolds. Arrangement arranged in a shape can also be adopted.

As shown in FIGS. 2 and 3, in the second embodiment, a silicone rubber water pipe 9 connected to a water pipe (not shown) via a hose 8 is provided with an inner diameter of the water pipe 9.

A pressure adjusting valve 13 is attached to a communication port of the joint 11 with the vent pipe 10. The water pipe 9 is housed in a cylindrical container 14 having an upper surface opening in a spirally wound state, and in the container 14, a powdery and granular material comprising a residue obtained by extracting water from sea ash at pH 5 to 14 is formed. , And a water pipe 9 is buried in the radiator 7 to constitute a dissolved oxygen-enriched water producing apparatus B.

The pressurizing pump 12 compresses air that has passed through a built-in filter, and can pressurize the air to, for example, about 1 to 5 atm. In addition,
Of course, a compressed air cylinder filled with an oxygen-containing gas or the like may be used as an oxygen-containing gas supply device instead of the pressurized pump 12.

As shown in FIG. 3, the L-shaped double pipe joint 11
Is installed inside a water-permeable pipe fitting 15 made of synthetic resin or a metal such as copper or iron.

A threaded surface 17 is formed inside one end of the water-passing pipe joint 15 constituting the L-shaped pipe double pipe joint 11, and a similar threaded surface is formed at one end of the hose joint 18. Then, the two can be attached in a liquid-tight manner.

In the second embodiment, a description has been given of a configuration in which the vent pipe 10 protrudes from the L-shaped water pipe fitting 15. However, the water pipe fitting 15 having such a form is used. It is needless to say that the ventilation pipe 10 may be formed to project obliquely from the water pipe 9.

In the above-described second embodiment, when the pressure in the ventilation pipe 10 is driven to be higher than normal pressure (atmospheric pressure),
The amount of oxygen permeating through the wall of the ventilation pipe 10 made of silicone rubber increases accordingly, and the dissolved oxygen-enriched water can be produced more efficiently.

Next, the ventilation pipe 19 shown in FIGS.
Is a collecting pipe that can be used in any of the above-described two embodiments. A large number of small-diameter silicone rubber pipes 20 are collected in parallel at predetermined intervals, and both ends of the collecting pipes are collectively placed on a disc 21. And the two discs 2
1 are hermetically attached to the inside of the funnel tube 22 by bonding or the like.

When such a ventilation tube 19 is attached to the first or second embodiment, a plurality of silicone rubber tubes 20 are provided.

A filter having an outer diameter of 3 mm, an inner diameter of 2 mm, and a pipe pressure of 0.5 mm was used, and air at a flow rate of 15 liter / min was supplied to the filter by a pump with a filter. A 10-liter container was filled with 8 kg of a powdery far-infrared radiator composed of a residue obtained by extracting seaweed ash at pH 5 to 14 with water.

When dissolved oxygen-enriched water was produced under the above-described conditions, the amount of dissolved oxygen in tap water as raw water was 7.4 m.
g / L, but the dissolved oxygen content of the dissolved oxygen-enriched water that passed through the water pipe was 8.1 mg / L, and water that was clearly rich in dissolved oxygen could be produced. Also, around the water pipe at the time of manufacture, there is no mixing sound of water and air,
Since tap water is enriched in dissolved oxygen without contacting the outside air, it could be produced sanitarily.

As described above, according to the present invention, a dissolved pipe is provided in which a ventilation pipe made of silicone rubber is disposed inside a water pipe, an oxygen-containing gas such as air is supplied to the ventilation pipe, and water is introduced into the water pipe. Since the oxygen-enriched water production system is used, the oxygen-containing gas and water flow through each pipe without directly contacting each other, and the dissolved oxygen-enriched water is continuously and efficiently produced with a sanitary and relatively simple structure. There is an advantage that it can be manufactured, and since it does not introduce bubbles into water, there is also an advantage that there is little noise in the driving state.

In the apparatus for producing dissolved oxygen-enriched water according to the present invention, since the water passing through the water pipe is affected by the predetermined far-infrared radiator, the water passing through the water pipe is heated and the silicone rubber is heated. This has the advantage that more oxygen is efficiently dissolved in the water in the water pipe.

Further, in the invention of the apparatus in which a pressure adjusting valve is attached to the ventilation pipe to supply a pressurized oxygen-containing gas, more oxygen is efficiently dissolved in the water in the water pipe by the increased gas pressure. There is also an advantage that the dissolved oxygen-enriched water can be produced extremely efficiently.

Further, in the invention in which the ventilation pipe is a collecting pipe in which a plurality of silicone rubber pipes are gathered in parallel, the contact area with water is larger than that of a ventilation pipe formed of a single silicone rubber pipe. Therefore, there is an advantage that the dissolved oxygen-enriched water can be efficiently produced.
