Description of the Related Art Conventionally, a method for increasing the concentration of carbon dioxide (CO 2 ) gas in an atmosphere in order to promote the growth of plants that carry out carbonic acid assimilation such as agricultural products and to increase the yield of agricultural products. , So-called CO 2 application was performed.
This method, LP gas, to generate CO 2 gas by combustion or by CO 2 gas cylinder of fossil fuels such as heavy oil,
By supplying this gas to a cultivation room such as a greenhouse, the concentration of CO 2 gas in the atmosphere is increased to activate photosynthesis, and as a result, the yield and quality of agricultural products and the like are improved.

現状であった。However, this method requires an airtight cultivation room such as a greenhouse, requires a large investment to install such a facility, and grows plants in the cultivation room. Inevitably, the cultivation area will be limited. Furthermore, if the CO 2 gas concentration in the cultivation room becomes too high, the health of human beings working may be impaired. When CO 2 gas is generated by burning fossil fuel, a large amount of nitrogen oxides (NO x )
Hazardous substances such as sulfur oxides (SO x ) and carbon monoxide (CO) are generated, which adversely affect the growth of plants and humans at work, and black smoke is generated due to incomplete combustion of the fuel. It may adhere to vinyl and reduce the amount of light reaching the plants. Moreover, since the temperature of the cultivation room rises due to the heat generated during combustion, it is necessary to pay attention to the temperature control of the cultivation room, and when ventilating, CO 2 gas is also discharged at the same time, which reduces the supply efficiency. Will end up. Especially in the summer, it was not possible to apply CO 2 in the CO 2 gas generation method by the combustion method because the indoor temperature rises too much.

自動化も困難である。Conventionally, as a CO 2 solution supply device used in this method, the above-mentioned combustion gas such as fossil fuel is supplied into a water tank, and CO 2 gas is directly contacted with water to generate CO 2 gas. A device for melting is considered.
However, according to this apparatus, a large amount of NO x gas and SO x gas contained in the combustion gas are also dissolved in water together with CO 2 gas, which adversely affects the growth of plants. Further, an apparatus for supplying CO 2 gas filled in a gas cylinder into a water tank and dissolving CO 2 by directly contacting with water has been considered, but this apparatus requires time and effort for replacement of the gas cylinder, Workability is poor and CO 2
Gas cylinders are also not suitable because they are expensive. Further, in any of the devices, the CO 2 gas is melted by directly contacting with water by supplying the CO 2 gas into the water tank,
Is supplied to plants, and according to this method, CO
2 Gas dissolution efficiency is poor. Further, since it is necessary to generate combustion gas and open the gas cylinder plug every time the CO 2 solution is required, workability is poor and automation is also difficult.

取り除くことができる。By the way, when water is electrolyzed for a long time, calcium (Ca) and magnesium (Mg) dissolved in water are dissolved.
Because like adheres so as to cover the cathode surface, CO 2
The dissolution efficiency will be significantly reduced. In particular, when a carbonaceous electrode is also used as the cathode, since there are many open pores, the adhesive force is extremely stronger than that of a metallic electrode such as stainless steel. Further, when the attached matter is physically removed, the electrode may be broken. Therefore,
In the case of a water electrolysis electrode in which the anode and the cathode are composed of carbonaceous electrodes, it is preferable to interpose a polarity switch between the electrolysis power source and the water electrolysis electrode. In this case, the cathode deposit can be easily removed by switching the polarity of the water electrolysis electrode.

命化を図った方が好ましい。The electric resistivity ρ of the carbonaceous electrode conventionally used as an electrode for electrolysis is 1 × 10 −3 Ω ·
cm and copper (ρ = 1.7 × 10 −6 Ω · cm)
Since it is considerably larger than metals such as iron and iron (ρ = 9.7 × 10 −6 Ω · cm), the ohmic loss in the electrode becomes larger than that of the metallic electrode. Further, due to the resistance of the electrode itself, the amount of voltage drop in the electrode increases to a nonnegligible distance from the current introduction portion of the electrode, and the current density of the anode and the cathode becomes non-uniform. Therefore, when the anode and the cathode are arranged in parallel, the electrodes are consumed unevenly and it is difficult to extend the life. Therefore, in a water electrolysis electrode constituted by using a carbonaceous electrode as an anode and a cathode, the anode and the cathode are formed into a plate shape, and with a plate-like anode as the distance from the current introduction portion of the water electrolysis electrode increases. When the plate-shaped cathodes are arranged so that the surface distance between them becomes gradually smaller, the current density between the electrodes can be made constant, so that the consumption of the electrodes can be made uniform. It is preferable to dispose the anode and the cathode in this way to extend the life of the electrode.

交流−直流変換器を介して電解した方が好ましい。There is no particular limitation on the method of producing a CO 2 solution using a carbonaceous electrode, and among the anode and the cathode, at least the anode is a carbonaceous electrode for water electrolysis,
It suffices to soak in the supplied water and apply a voltage between the electrodes to electrolyze the water. The electrolysis voltage at this time depends on the distance between the electrodes and the amount of impurities contained in water, and cannot be uniquely determined. However, in the case of electrolyzing clean water, the distance between the electrodes is usually 5 to 10 mm. If 5 V or more, electrolysis can be performed. Here, at the time of electrolysis, it is preferable that the value obtained by dividing the total current by the operating area (current density) is 10 mA / cm 2 or less. When the current density exceeds 10 mA / cm 2 ,
This is because the surface of the carbonaceous electrode may be roughened and the electrolysis efficiency may be deteriorated or the life may be shortened. The electrolysis method is
A carbonaceous electrode is used for at least one of the anode and the cathode, which is an anode, and is brought into contact with water that has been supplied with water. It is usual to use a carbonaceous electrode for the cathode electrode, but a metal electrode such as stainless steel may be used for the cathode. Of course, electrolysis may be carried out in alternating current, but since electrolysis efficiency decreases,
It is preferable to electrolyze through an AC-DC converter.

きる。Also, the preferred C of the CO 2 solution formed is
The O 2 concentration range is 10 to 2000 mg / liter (room temperature). The reason will be described below. This is because CO 2 is a water-soluble substance, but if its concentration is less than 10 mg / liter, the growth promoting effect becomes weak. On the other hand, CO
2 dissolves in water and dissociates to generate hydrogen ions (CO 2 +
H 2 O ⇔ HCO 3 − + H + ), such a solution shows weak acidity, but if it exceeds 2000 mg / liter, the pH value of most plants will be too small, and the growth thereof will be poor. This is because it becomes less desirable.
Particularly optimum concentration is 30-500 mg / liter (room temperature)
Is. Here, the pH value depends on the carbonate hardness (KH) of water and the CO 2 concentration, and when KH is too low, p
The H value changes abruptly with a slight change in CO 2 concentration, and CO 2 also becomes difficult to dissolve, so caution is required. K
H generally exists naturally in the range of 0 to 140 ° dH, but any value can be used. However, since the concentration of CO 2 gas that can dissolve KH is in a proportional relationship, if a substance that raises KH, such as calcium carbonate, is added to raise KH, more CO 2 can be dissolved in water.

御される。When the contained water is electrolyzed, when both the anode and the cathode of the water electrolysis electrode are composed of carbonaceous electrodes, the electrode between the water electrolysis electrode and the electrolysis power source is separated. It is preferable to interpose a polarity switching device for switching the polarity. This is because the Ca, Mg, etc. adhering to the cathode can be removed and the CO 2 solution is generated on the side of the electrode that has newly become the anode simply by switching the polarity. Also in the case of this configuration example, a polarity switch (not shown) may be interposed between the water electrolysis electrode and the electrolysis power supply. The switching of the electrodes at this time is controlled so that the polarity is switched when the electrolysis time reaches a predetermined time in the range of, for example, 10 minutes to 4 hours, depending on the quality of the water to be electrolyzed.
