DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below.
The carbonated water washer of the present invention is a raw water supply section that takes or stores raw water, a carbon dioxide addition section that adds carbon dioxide to the raw water to carbonate it, and discharges the carbonated water toward a part of the body. And a discharge portion.
The raw water supply unit in the carbonated water cleaning device of the present invention is a water intake pipe that can be connected to a raw water source such as a water tap or a water storage tank to take in raw water, a water storage tank that can store a certain amount of raw water, or the like.
When a water intake pipe is used as the raw water supply section, it can be connected to a raw water source such as a water tap so that raw water can be easily taken. When a water storage tank is used, a carbonated water scrubber can be used even in a place where there is no raw water source. The capacity of the water storage tank is not limited as long as it can store a certain amount of raw water, and a small tank with a capacity of about several hundred ml, a tank with a large capacity of about 10 m ³ , and the like can be exemplified.
Carbon dioxide gas is added to the raw water from these raw water supply sections at the carbon dioxide addition section to form carbonated water.
[0007]
The carbon dioxide addition section has a function of introducing carbon dioxide from a carbon dioxide source such as a carbon dioxide cylinder and adding carbon dioxide to the raw water. If carbon dioxide gas can be added to the raw water before the raw water is discharged from the discharge section, there is no restriction on the location and form of the carbon dioxide addition section, but the raw water supply section has a water intake pipe for taking the raw water. The carbon dioxide adding section is preferably an adding device for adding carbon dioxide to the raw water flowing through the intake pipe.
FIG. 1 shows an example of an addition apparatus which is one form of the carbon dioxide addition part of the carbonated water washing device of the present invention. Here, the addition apparatus is introduced into the intake pipe 2 from the side of the intake pipe 2. Tube 3. A check valve 4 may be provided in the introduction pipe 3. A carbon dioxide source such as a carbon dioxide cylinder can be connected to the introduction pipe 3, and carbon dioxide can be supplied from the outside. Carbon dioxide gas introduced into the intake pipe 2 from the introduction pipe 3 is added to the raw water 1 flowing through the intake pipe 2.
The introduction pipe 3 used here is not particularly limited as long as carbon dioxide gas can be added to the intake pipe 2, but by providing a check valve 4 in the introduction pipe 3, the raw water 1 is supplied with a carbon dioxide supply source. This is preferable because it can prevent backflow to the side.
Since carbon dioxide has a high solubility in water, even when carbon dioxide is blown directly into the raw water 1 that circulates, the carbon dioxide can be sufficiently dissolved in the raw water 1 to obtain carbonated water having a concentration of several hundred ppm.
In this way, the raw water supply section includes the intake pipe 2, and the carbon dioxide addition section is an addition device such as the introduction pipe 3 that can add carbon dioxide into the raw water 1 flowing through the intake pipe 2. Carbon dioxide gas can be blown directly into the raw water 1 that circulates, and carbonated water can be obtained easily. The obtained carbonated water further flows through the intake pipe 2 and is sent to the discharge section.
[0008]
When the raw water supply unit has a water storage tank that can store a certain amount of raw water, the carbon dioxide gas addition unit has a diffuser pipe for introducing carbon dioxide gas into the water storage tank, so that highly concentrated carbonated water can be obtained. preferable.
Specifically, as shown in FIG. 2, a mode in which a diffuser pipe 6 or the like is introduced into the water storage tank 5 as a carbon dioxide addition part, and carbon dioxide gas is bubbled into the raw water 1 from the diffuser pipe 6 and added. A carbon dioxide gas source such as a carbon dioxide gas cylinder can be connected to the air diffuser 6 and carbon dioxide gas can be supplied from the outside. The carbonated water to which the carbon dioxide gas has been added is supplied from the water storage tank 5 to the discharge section using a liquid feed means such as a liquid feed pump (not shown) or the pressure of the carbon dioxide gas as a drive means. The diffuser pipe 6 used here is not particularly limited as long as carbon dioxide can be added to the water storage tank 5, but any carbon dioxide can be ejected into the raw water 1 as fine bubbles. The contact area between the gas and the raw water 1 is increased, and high-concentration carbonated water can be obtained efficiently, which is preferable. For example, when a porous ceramic plate 6 a having a large number of fine holes is used at the tip of the air diffusion tube 6, carbon dioxide gas can be ejected as fine bubbles. Alternatively, if a porous ceramic tube or a porous hollow fiber membrane is used in the portion of the diffuser tube 6 introduced into the water storage tank 5, fine bubbles are generated not only from the tip of the tube but also from the side of the tube. This is preferable because it can be ejected and carbonated water can be obtained more efficiently. Moreover, the water storage tank 5 used here may be provided only for the purpose of adding carbon dioxide gas to the raw water 1, or may be used in combination with a water storage tank for storing the raw water 1 or the like.
[0009]
When carbon dioxide gas is introduced and added to the raw water 1 stored in the water storage tank 5 in this way, the contact time between the raw water 1 and the carbon dioxide gas can be made sufficiently long, so a high concentration carbonated water close to a saturated concentration of about 1000 ppm. Can be obtained. Moreover, since the pressure in the tank 5 rises by blowing in carbon dioxide gas by making the water storage tank 5 into a closed system, carbonate water of higher concentration can be obtained.
Therefore, it is preferable that the raw water supply unit includes the water storage tank 5 and the carbon dioxide addition unit includes the air diffuser 6 for introducing the carbon dioxide gas into the water storage tank 5 because highly concentrated carbonated water can be obtained. Moreover, by using a small and small-capacity water storage tank 5, a portable carbonated water scrubber can be obtained.
[0010]
In order to obtain high-concentration carbonated water more efficiently, it is preferable that the carbon dioxide gas addition part includes a hollow fiber membrane module including a hollow fiber membrane having a gas-permeable non-porous layer. When the raw water and carbon dioxide gas are brought into contact with each other through a hollow fiber membrane having a gas-permeable non-porous layer, the contact area between the raw water and carbon dioxide gas greatly increases, and the carbon dioxide gas can be efficiently dissolved in the raw water. it can.
The material used for the gas permeable non-porous layer may be segmented polyurethane, silicone polymer, low density polyethylene, polyolefin such as poly-4-methylpentene-1, polyacrylamide, etc. Polymers such as urethane having a high gas permeability coefficient are preferred. By dissolving carbon dioxide gas in water through such a non-porous layer, carbon dioxide gas is added to water as a molecular state or as ultrafine bubbles, so that the dissolution efficiency can be improved. Further, since the non-porous layer does not allow water to pass therethrough, it is possible to prevent back flow of water into the gas phase.
The hollow fiber membrane having a non-porous layer used here is, for example, a three-layer structure in which a non-porous urethane thin film 7 as shown in FIG. 3 is sandwiched between both sides by a porous polyethylene membrane 8. Examples thereof include a yarn film 9 and the like. By making the hollow fiber membrane 9 into a three-layer structure, the non-porous urethane thin film 7 is protected by the porous polyethylene membrane 8, which is preferable. The form of the hollow fiber membrane module is not limited as long as the hollow fiber membrane 9 having a gas permeable non-porous layer can be used to contact raw water and carbon dioxide gas. For example, FIG. As described above, the hollow fiber membrane module 10 in which both ends of the plurality of hollow fiber membranes 9 are fixed to form a hollow fiber membrane element and the hollow fiber membrane element is housed in the container 15 is preferable.
[0011]
FIG. 4 is a cross-sectional view of the hollow fiber membrane module 10, and both ends of a large number of hollow fiber membranes 9 are supported and fixed by a potting material 11 such as an epoxy resin while keeping the open state of the hollow part. The raw water inlet 12 of the hollow fiber membrane module is connected to a raw water supply unit that takes or stores the raw water, the raw water is supplied from the raw water inlet 12, and the raw water is passed through the hollow portion of the hollow fiber membrane 9. On the other hand, a carbon dioxide source such as a carbon dioxide cylinder is connected to the carbon dioxide supply port 13 to supply carbon dioxide, and the carbon dioxide is press-fitted from the outside of the hollow fiber membrane 9 into the inside hollow portion. Carbon dioxide gas passes through the hollow fiber membrane 9, enters into the hollow part as molecular or ultrafine bubbles, and is added to the raw water flowing through the hollow part. Since carbonated water is obtained from the carbonated water outlet 14, carbonated water can be discharged from the discharge part by connecting the carbonated water outlet 14 and the discharge part.
When the hollow fiber membrane module 10 that contacts the raw water and the carbon dioxide gas through the hollow fiber membrane 9 is provided in the carbon dioxide gas addition unit, the contact area between the raw water and the carbon dioxide gas greatly increases, and the dissolution of the carbon dioxide gas occurs. Efficiency is improved. Therefore, highly concentrated carbonated water can be obtained efficiently. In addition, even if the small hollow fiber membrane module 10 is used, the raw water and the carbon dioxide gas are sufficiently in contact with each other.
[0012]
Carbonated water is sent to the discharge section and discharged. The discharge unit discharges carbonated water toward the body, and is a nozzle-like one in which the tip of the tube is gradually reduced in diameter, a shower head having a large number of holes, or the like. There is no restriction | limiting in particular in the shape of a discharge part, a magnitude | size, etc., It selects suitably according to the washing | cleaning feeling calculated | required and the site | part to be cleaned of a carbonated water cleaner.
