た、主として水の電気分解の前処理として使用さ
れる水の炭酸除去装置に関する。[Detailed description of the invention] [Field of application of the invention] The invention relates to a device for removing carbon dioxide from water. The water is mainly used as pre-treatment for electrolysis of water, which removes carbon dioxide gas etc. from the water by foaming water and separating the foam into gas and liquid in a separation chamber separate from the foaming chamber. This invention relates to a carbon dioxide removal device.
〔発明が解決しようとする課題〕
一般に、地下水、河川の水には遊離炭酸の状態
で炭酸が多く含まれている。この炭酸の起源は、
ほとんど、雨水に溶けている炭酸ガスであるが、
また、土壌中で生物の呼吸作用、バクテリアの分
解作用で発生する炭酸ガスでもある。そして炭酸
ガスの溶解と解離の関係は、
CO2＋H2O H2CO3（炭酸）
H2CO3 H+＋HCO3
HCO3 H+＋CO3
である。[Problems to be Solved by the Invention] Generally, groundwater and river water contain a large amount of carbonic acid in the form of free carbonic acid. The origin of this carbonic acid is
Most of it is carbon dioxide dissolved in rainwater,
It is also carbon dioxide gas, which is generated in the soil by the respiration of living things 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 .
従つて、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, H + and HCO 3 - or
When it is separated into H + and CO 3 - , it becomes OH - + H + H 2 O, and the hydroxyl groups are consumed, 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

もしくは、電極表面にスケールとして付着し、通
電率を低下させる。このため、Ca-を消耗してし
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. Alternatively, it adheres to the electrode surface as scale, reducing the current conductivity. For this reason, it also has the disadvantage of consuming Ca - .
そこで、水中に空気を吹き込むことにより、泡

単に水槽内の水に空気を送つて泡立たせる方式で
あるため気泡が大きくなり充分な気液接触面積が
得られず、また、水槽内の水全体をまんべんなく
空気と接触させることができないため充分な効果
を得ることができなかつた。 Therefore, a method was adopted in which air is blown into the water to create bubbles and remove carbon dioxide gas. Here, the conditions are gas solubility in water (atmospheric pressure and
Taking advantage of the fact that the temperature remains constant, the amount of dissolved carbon dioxide is substantially reduced by replacing carbon dioxide with air. A specific method for this is to supply air through a plate with a large number of holes at the bottom of the tank.
The air that rises in bubbles through the water in the aquarium,
The surface of the bubbles comes into contact with water and replaces carbon dioxide gas in the water. However, since this method simply sends air to the water in the aquarium to create bubbles, the bubbles become large and a sufficient air-liquid contact area cannot be obtained, and it is difficult to evenly contact the entire water in the aquarium with air. Because it was not possible to do so, sufficient effects could not be obtained.

率良く除去することにある。 The present invention was developed to solve the above problem, and its purpose is to diffuse water onto the porous partition wall to a thickness below a certain level, and to supply finely divided pressurized air from below the partition wall. By doing so, all the water passing through the bubbling chamber is foamed, and the water bubbles are separated into gas and liquid in a gas-liquid separation chamber communicating with the outside of the bubbling chamber, thereby efficiently removing carbon dioxide from the water in a short time.

The above-mentioned object of the present invention is to provide an overflow wall of a predetermined height on one side of a bottom partition plate having a porous partition wall, a whisking chamber with a bubble outlet above the overflow wall, and an overflow of the whisking chamber. a gas-liquid separation chamber provided on the downstream side of the flow wall; a means for continuously supplying water from one end of the foaming chamber so as to diffuse onto the partition wall; The overflow wall controls the thickness of the water layer on the partition wall of the whisking chamber to a predetermined value or less, and the air bubbles discharged beyond the overflow wall are vented in the separation chamber. This can be achieved by a water carbonation removal device that separates the liquid and recovers the water.
尚、空気圧送手段には電熱などによるヒーター
を設け、加熱空気を圧送するようにしてもよい。 Note that the air pressure feeding means may be provided with a heater using electric heat or the like to force feed the heated air.

In the present invention, water is diffused and sprayed onto the partition wall at the bottom of the foaming chamber, and at the same time, water is forcibly foamed by fine pressurized air that passes through the micropores of the partition wall while flowing over the porous partition wall. Therefore, all the water introduced into the foaming chamber comes into contact with the compressed air evenly and becomes foamed. In this case, the layer thickness of water on the partition wall is regulated to a certain layer thickness or less by the height of the overflow wall between the partition wall and the gas-liquid separation chamber, so bubbles do not grow and are maintained as fine bubbles.
また、泡立て室に充満した泡は圧送空気の圧送

る。 Further, the foam filling the foaming chamber is pushed out over the overflow wall into the gas-liquid separation chamber by the force of the pressurized air, and is separated into gas and liquid. Therefore, the water generated in the gas-liquid separation chamber is water that has been separated from water bubbles, that is, water that has been guaranteed to come into contact with fine air, so it is water from which carbon dioxide gas has been effectively removed by replacing it with air. is obtained.
尚、空気圧送手段にヒータを設けた場合は圧送
空気によつて泡立てられる際に水の温度が上昇す
るため水のガス溶存度が低下し、炭酸ガスは一層
効率的に除去される。 If the air pressure feeding means is provided with a heater, the temperature of the water increases when it is bubbled by the pressure air, so the degree of gas solubility in the water decreases, and carbon dioxide gas is removed more efficiently.

When the pressurized air fragments and enters the foaming chamber 2 through the partition wall 4, it foams the water flowing on its surface. This whisking rises to the ceiling of the whisking chamber 2, is further pushed toward the overflow wall 11, and at a position beyond the overflow wall 11,
In the gas-liquid separation chamber 12, air containing carbon dioxide gas and water from which carbon dioxide gas has been removed are separated.

As described above, in the present invention, the fine water droplets injected from the nozzle of the fountain pipe collide with the porous partition wall and are dispersed, and at the same time, the water diffused and injected onto the partition wall is dispersed by the compressed air from below the partition wall. Because of the foaming, the continuously introduced water comes into contact with gas and liquid in a short time, promoting the replacement of dissolved carbon dioxide gas in the water with air. In addition, the water bubbles generated in the bubbling chamber are led to a gas-liquid separation chamber separate from the bubbling chamber to separate the water, resulting in water that has been removed to the maximum extent possible, including carbon dioxide and chlorine gas. Efficient generation of electrolyzed alkaline ionized water can be achieved by electrolysis.
