行される水の炭酸除去装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is primarily concerned with the removal of carbonation from water, which is carried out as a pre-treatment, for example, for the purpose of converting tap water into drinkable water by electrolysis or electroosmosis. It is related to the device.
一般に、地下水、河川の水には遊離炭酸という

である。 Generally, groundwater and river water contain a large amount of carbonic acid called free carbonate. The origin of this carbonic acid is mostly carbon dioxide gas dissolved in rainwater, but it is also carbon dioxide gas generated in the soil by the respiration of living organisms and the decomposition of bacteria. The relationship between dissolution and dissociation of carbon dioxide gas is CO 2 + H 2 OH 2 CO 3 (carbonic acid) H 2 CO 3 H + + HCO 3 - HCO 3 - H + + CO 3 - .
したがつて、電解作用によつて、陰極室側の水
に水酸基を多量に発生しても、H+とHCO3 -ある
いはH+とCO3 -に分かれた状態で、
OH-+H+→H2O
となり、水酸基を消耗してしまうので、電解効率
が著しく低下することになる。 Therefore, even if a large amount of hydroxyl groups are generated in the water on the cathode chamber side by electrolytic action, they will be separated into H + and HCO 3 - or H + and CO 3 - , and OH - +H + →H 2 O and consumes the hydroxyl group, resulting in a significant drop in electrolytic efficiency.
また、電解作用を与えた時、陰極室側には有用

してしまう欠点もある。 In addition, when electrolytic action is applied, useful calcium ions gather on the cathode chamber side, but the carbonic acid mentioned above shows a reaction of H 2 CO 3 +Ca→H 2 +CaCO 3 , becomes calcium carbonate, and precipitates. Otherwise, it may adhere to the electrode surface as scale, reducing the current conductivity. For this reason, it also has the disadvantage of consuming Ca - .

れない状況にある。 Therefore, a method was adopted in which air was blown into the water to create bubbles and remove carbon dioxide gas. This takes advantage of the fact that the degree of gas solubility in water is constant depending on the conditions (atmospheric pressure and temperature), and by replacing carbon dioxide with air, the amount of dissolved carbon dioxide is substantially reduced. In this specific method, air is supplied through a plate with many holes at the bottom of the aquarium, and the air rises in the form of bubbles through the water in the aquarium, and is brought into contact with the water on the surface of the bubbles. There are some that achieve replacement of carbon dioxide gas in water. However, in this method, the amount of air supplied relative to the amount of water is small, the bubbles are large, and a sufficient surface area of gas-liquid contact cannot be obtained, so that the expected carbon dioxide removal cannot be achieved.

去装置を提供しようとするものである。 The present invention was made based on the above circumstances, and in a situation where fragmented pressurized air is ejected through a porous partition wall, water is diffused along the partition wall, and all the water is removed. The object of the present invention is to provide an apparatus for removing carbon dioxide from water, which achieves a high level of air contact by foaming, thereby effectively removing carbon dioxide gas in a short period of time.

In the figure, reference numeral 1 denotes a box-shaped main body of the apparatus, in which a foaming chamber 2 is provided in the center and a pressurized air supply chamber 3 is provided at one end. One end of the bubbling chamber 2 is provided with a porous material such as ``Pulcon'' (trade name), which is made by unglazing or semi-molten agglomeration of fine particles of synthetic resin, so as to separate it from the pressurized air supply chamber 3. A porous partition wall 4, such as a plate or the like, having pores is provided, and the divided pressurized air is supplied from the pressurized air supply chamber 3 into the bubbling chamber 2 through the partition wall 4. The pressurized air supply chamber 3 is connected to a blower 5, and a heater 7, such as an electric heater, is provided in a communication area 6 between the blower 5 and the pressurized air supply chamber 3.

る。 On the other hand, above one end side of the whisking chamber 2, a fountain pipe 8 is arranged corresponding to the width of the whisking chamber 2, and a fountain pipe 8 is provided through nozzles 9 arranged in parallel in the longitudinal direction of the fountain pipe 8. Water is diffused and released toward the partition wall 4. The fountain pipe 8 is connected to a water pipe (not shown) via a solenoid valve 10. Further, apart from the fountain pipe 8, for example, on the opposite side of the bubbling chamber 2, a gas-liquid separation chamber 12 is connected via an overflow wall 11, and the bottom of the gas-liquid separation chamber 12 A discharge port 14 to the water storage tank 13 is opened at.

とが分けられる。 In such a configuration, by driving the blower 5 and opening the solenoid valve 10 (this can be done manually, but it can also be done automatically by a signal from a level detector installed in the water tank 13, etc.). When the pressurized air fragments and enters the foaming chamber 2 through the partition wall 4, it foams the water flowing down to its surface. This whisking moves the whisking chamber 2 in the direction of the air flow and is pushed toward the overflow wall 11 side. Then, at a position beyond the overflow wall, air containing carbon dioxide gas and water from which carbon dioxide gas is removed are separated in a gas-liquid separation chamber 12.

うに設定される。 The pumping force of the supplied air is so strong that even if water remains in the bubbling chamber 2, the water bubbles flowing from the partition wall 6 to the gas-liquid separation chamber 12 will not be obstructed by the water. The amount of water supplied to the fountain pipe 8 is set to be a huge amount of air.

きる。 The present invention has been described in detail above, and includes a whisking chamber provided with a porous partition on one end side, a means for diffusing supply water along the partition, and a means for pumping air into the whisking chamber through the partition. and a means for extracting water bubbles formed by dispersion of water in the bubbling chamber and separating the gas and liquid, so that the water is forced onto the partition wall by a finely divided air stream. The water is then finely whipped, sent sequentially to expand the bubbles, and finally released to separate the gas and liquid.
For this reason, unlike the method of blowing air into the water,
By increasing the amount of air contact per area, the carbon dioxide contained in the water is taken out into the air and replaced with air, making it possible to significantly increase carbon dioxide emissions.
