Description

  The present invention was devised from the well-known knowledge that microbubbles promote the absorption of biological substances, and the gas forming the microbubbles of microbubbles has a relatively high carbon dioxide component concentration.

  As described in the doctoral dissertation of Non-Patent Document 1, plant carbon dioxide absorption depends on the carbon dioxide concentration of the surrounding gas. Naturally, the higher the density, the better. The density range is appropriate, and the correlation is nonlinear and complicated. Moreover, it is easily imagined that it differs depending on the plant species and their state.

  Non-Patent Document 1 studies such a nonlinear and complex correlation, and shows that such a correlation can be determined recursively from experimental data as appropriate.

  Non-Patent Document 1 shows that the relationship between the carbon dioxide concentration of the surrounding gas and the opening degree is also correlated while observing the pore opening degree of the leaves under a microscope.

  Although there is no clarification in the literature here, carbon dioxide absorption in the pores suggests that the presence of moisture is important because carbon dioxide in the “gas phase” is not directly absorbed into the pores .

  In other words, since there is another knowledge that the amount of absorption decreases or the pores do not open if there is no water, carbon dioxide is dissolved in water or in a state similar to that of dissolved gas. It is thought that it moves to the site and is absorbed as appropriate.

  On the other hand, so-called “microbubbles” are known (see Non-Patent Document 2). I would like to propose here the idea of using this as a state similar to the state of dissolved gas in which carbon dioxide is dissolved in moisture.

  Microbubbles are said to have different properties from ordinary bubbles. This “microbubble” has a low concentration type: there is a distribution peak around 30 μm in diameter, the bubble concentration is about several hundreds / mL, and the appearance is that the water is slightly cloudy. “Microbubbles” have a high concentration type: a bubble distribution peak in the vicinity of 10 μm, the number of bubbles is more than several thousand / mL, and there are some that look like milk.

  In the present invention, if the “microbubble” is the “state similar to the state of dissolved gas in which carbon dioxide is dissolved in water”, the carbon dioxide absorption in the pores of the plant is greatly improved. Invented.

  Other findings that led to this idea are explained: “Microbubbles promote the uptake of animal cells”. That is, it is a finding that when there is a liquid containing microbubbles in the vicinity of the surface of an animal cell, it stimulates the cell membrane and promotes substance uptake (endocytosis) at the cell membrane.

  Specifically, oysters and scallops are encouraged to take up substances by subsea micro-bubbling, which increases the size. Already put into practical use in oyster farming and scallop farming, products are on the market.

  Further, in the human body, data is taken that the blood flow value increases when the blood flow on the skin surface is measured in a state where micro bubbling is performed in a bath. For this reason, activation of cellular activity of receiving oxygen from hemoglobin and expelling carbon dioxide at the cellular level of the human body is observed, and the former phenomenon of promoting oxygen uptake, which is oxygen uptake, has occurred.

  As a gas effect of such an acceleration phenomenon, (1) time required for cell culture is shortened, (2) substance uptake for converting normal cells into iPS is promoted, and iPS cell (induced pluripotent stem cell) acquisition yield is increased. Improvements are being conducted, mainly in the biotechnology field.

  Here, empirical differences between the above-mentioned two types of “microbubbles”: the low concentration type (30 μm) and the high concentration type (10 μm) generally indicate that the various effects given by the high concentration type (10 μm) are lower. It is much larger than that of the type (30 μm).

  Therefore, when the present invention is carried out, the high concentration type (10 μm) is similarly effective.

  A technique for generating high-concentration type (10 μm) microbubbles is described in Patent Document 1, for example. On the other hand, Patent Document 2 and Patent Document 3 describe low-concentration type (30 μm) or lower (millimeter-scale) type technologies having a larger bubble diameter.

  In Patent Document 1 and Patent Document 2, there is a description of “promotion of substance absorption from the outside of a cell” by microbubbles such as microbubbles, which is the same concept as the present invention. However, since there is no clear description about the carbon dioxide absorption of plants, the patentability of the present invention is not impaired.

  FIG. 1 is a schematic diagram for explaining the outline of the present invention. According to knowledge (conventional technology) based on conventional research, plants were placed in a high-pressure environment of carbon dioxide gas or carbon dioxide-rich gas was sprayed on the plant, but a significant absorption promotion effect of carbon dioxide was obtained. There wasn't.

  In the present invention, the microbubble-containing liquid composition using carbon dioxide as a gas source of microbubbles and the liquid composition were solved by misting the liquid composition and giving it to the plant (see the right side of FIG. 1).

  On the other hand, as an application of microbubbles, one of the inventors has applied for the inventions of Patent Document 4 to Patent Document 7. These control the environment as the gas phase inside the liquid phase of the culture solution with microbubbles, tuning of the ease of growth characteristic of individual cells that could not be done conventionally, or external substances characteristic of individual cells Is the technology to control the growth of single cells such as yeast and the production of ethanol, etc., which could not be achieved by conventional control of the gas phase environment (promoting endocytosis).

  Among the inventions of Patent Document 4 to Patent Document 7, Patent Document 4 describes a microbubble microbubble in which a gas component containing carbon dioxide is changed, and a device for generating the same. Patent Document 5 describes a microbubble having carbon dioxide microbubbles that can be used in the present invention and a device for generating the same (see FIG. 5).

  Further, Patent Document 6 suggests a method and apparatus that can change the particle size distribution of microbubbles relatively easily.

In addition, in the invention of Patent Document 7, a method of generating heat during micro-bubbling is described, and it is suggested that this method is useful for adjusting an environmental factor that is important for living organisms including plants.

  The problems of the present invention are as follows: (1) Promotion of fixation of carbon dioxide gas to reduce greenhouse gases and help prevent global warming; (2) Carbon dioxide assimilation of carbon dioxide gas generated by combustion and the like It will be converted into food and converted to food, which will help solve the food problem.

  To summarize the present invention, carbon dioxide microbubble water bubbled with a microbubbler and contained as microbubbles is misted and sprayed onto the plant on a ground plant. Misting is not required for underwater plants. Carbon dioxide microbubble water bubbled and contained as microbubbles is added directly to fresh water and seawater near plants.

  Both are inventions of an apparatus and method for controlling a desired absorption by mixing a gas inside the structure and diluting carbon dioxide to be absorbed in a gas-sealed large structure that covers the growing plant.

  That is, (refer to claim 1 and FIG. 3), a system that promotes carbon dioxide absorption of plants growing inside a gas-sealed structure to improve the environment and increase carbon dioxide assimilation, Or a system having means or devices E1 to E5 in the vicinity.

  E1, means for supplying carbon dioxide with concentration “A” from the outside of the gas-sealed structure, E2, carbon dioxide with concentration “A” supplied from E1, and the internal gas of the structure are mixed, Carbon dioxide concentration adjusting means for obtaining carbon dioxide having a desired concentration “B” (where A is a value larger than B) E3, carbon dioxide holding means for adjusting the adjusted concentration “B”, E4, A microbubble-containing device for producing a microbubble-containing liquid composition using carbon dioxide having a concentration “B” held by the holding means E3 as a gas source of microbubbles, and containing microbubbles generated by the microbubble device E4 It is a means for guiding the liquid composition to a group of plants that grow inside the gas-sealed structure.

  In other words, this system is a method for improving the environment and increasing carbon dioxide assimilation by promoting carbon dioxide absorption of the plant group P, which is installed in or near the gas-sealed structure. A method of performing at least the steps F1 to F5 with the means or apparatus E1 to E5.

  A step of supplying carbon dioxide having a concentration “A” from the outside of the gas-sealed structure by F1 and E1, and a carbon dioxide having a concentration “A” supplied from E1 and the internal gas of the structure by F2 and E2. In the carbon dioxide concentration adjustment step (where A is a value larger than B) F3 and E3, the adjusted concentration “B”. The step of holding the carbon dioxide of the liquid tank, and further sucking the liquid in the liquid tank by the liquid suction means while sucking the carbon dioxide having the concentration “B” from the holding means by the micro bubbling device of F4 and E4. A step of discharging microbubbles having a particle size of 30 μm or less from the discharge nozzle into the liquid, and the liquid composition discharged from the discharge nozzle of the micro-bubble device E4 is gas-sealed by F5 and E5. A step of inducing the vegetation growing in the interior of the object.

  Here, E1 (F1), that is, means (process) for supplying carbon dioxide having a concentration “A” from the outside of the gas-sealed structure is linked to the carbon dioxide centralized processing technology currently being rapidly researched and developed. The system (process) may be configured.

  Carbon dioxide intensive treatment technology has been developed to reduce greenhouse gases to prevent global warming. For example, carbon dioxide produced at power plants and steelworks is rapidly frozen and transferred to dry ice. It is a technology that makes it easy to make it centralized at the destination.

  In these carbon dioxide treatment technologies, the carbon dioxide concentration is generally high, as can be seen by recalling the state of sublimated dry ice. Such high-concentration carbon dioxide was described here as carbon dioxide having a concentration of “A”.

  The concentration “A” is not a concentration suitable for absorption by plants, so it needs to be diluted.

  Since it is appropriate and simple to use the internal gas of the gas-sealed structure for the dilution, the carbon dioxide having the concentration “A” supplied from E1 of E2 (F2) and the internal gas of the structure are used. Carbon dioxide concentration adjusting means (process) was prepared by mixing to obtain carbon dioxide having a desired concentration “B”.

  Naturally, as pointed out in the description of Non-Patent Document 1 above, the value of the concentration “B” varies depending on the plant species and their state, but these may be determined experimentally as appropriate. Good.

  Even if there are a wide variety of plants with gas-sealed structures, there should be a cascaded carbon dioxide utilization chain like the sunlight utilization chain in the dense forest, so a plant using high-concentration carbon dioxide at the top of this chain It may be determined experimentally as appropriate with a focus on.

  Further, (see claim 2, FIG. 2), the gas-sealed structure covers a group of plants that grow on the ground, and the microbubble-containing liquid composition generated by the microbubble device E4 is misted (misted). It is preferable that a mist generating means E6 is further provided downstream of the liquid composition guiding means E5.

  If this is reduced to a method (Claim 6), the gas-sealed structure covers the plant group growing on the ground, and further comprises the following step F6. F6 is a step of misting (misting) the liquid composition discharged from the discharge nozzle of E4 by the misting (misting) means E6 further provided downstream of E5.

  FIG. 2 is an explanatory diagram of “a mist of microbubble-containing liquid” in FIG. 1, wherein M1 is a mist particle formed by making a liquid containing microbubbles into a mist form. M1R is the particle size of M1 and is a sub-millimeter size slightly smaller than millimeters. M2 shows that the microbubbles of carbon dioxide gas contained in the liquid containing microbubbles before misting remain in the particles of M1 misted with E6. M2R is the particle size of M2, and what can remain inside M1 is mainly microbubble microbubbles with a particle size of 30 μm or less, and these are clusters of gas molecules (aggregates of gentle bonds). I believe.

  For example, a known device and method such as a high-pressure nozzle and an ultrasonic wave may be used as the mist generating means.

  Here, there is absolutely no adverse effect that microbubbles collapse due to mist formation, but there are various mist formation means and tuning methods. It is only necessary to tune to the optimum value experimentally while accumulating the correlation data of M1R and M2R obtained as a result of changing the value of energy applied to the ultrasonic generation source.

  Further, (refer to claim 3 and FIG. 4), the gas-sealed structure covers the plant group that grows in water, and the micro bubbling device E4 is disposed at a height higher and lower than the water depth of the plant group that grows in water. In this case, the system further includes means E7 for pressurizing the liquid composition containing microbubbles generated by E4 according to the difference in height, or the micro bubbling apparatus E4 is provided with a water depth of a plant group that grows in water. When it arrange | positions in the substantially same height position, it is preferable to further have the means E8 which pressurizes the carbon dioxide of density | concentration "B" according to the water depth of this plant group.

  If this is reduced to a method (Claim 7), the method further comprises the following steps F7 or F8, and F7 arranges the micro bubbling device E4 at a high and low position higher than the water depth of the plant group growing in water. In this case, the step of pressurizing the microbubble-containing liquid composition with the pressurizing means E7 in accordance with the difference in the depth of the water depth, F8 causes the microbubble device E4 to be approximately the same as the water depth of the plant group growing in water. In the case where it is arranged at a position, it is a step of pressurizing carbon dioxide having a concentration “B” by the pressurizing means E8 according to the water depth of the plant group.

  The plant group that grows in water is generally all species that perform photosynthesis in water, such as aquatic plants, seaweeds, and algae, but chlorella and giant kelp (giant kelp) are preferred.

  The mist making means and the mist making process suitable for the above-mentioned ground plants according to claims 2 and 6 are unnecessary for the underwater plants. Instead, it is necessary to discharge the liquid or gas in water or under water pressure by means / steps for increasing the pressure described in claim 3.

  These underwater discharge means and processes may be diverted from underwater discharge engineering technology using a known underwater pump or the like, and are technically easy.

  Further, specifically for the micro bubbling apparatus E4 (see claim 4 and FIG. 5), E4 is connected to means for sucking carbon dioxide having a concentration “B” from the holding means E3, liquid suction means, and the liquid discharge means. A vortex pump and a discharge nozzle having a discharge end inside a gas-sealed structure, wherein the vortex pump rotates a built-in impeller with a motor, and sucks carbon dioxide with a concentration of “B”. While sucking carbon dioxide having a concentration of “B”, the liquid suction means sucks the liquid in the liquid tank, and microbubbles containing microbubbles having a particle size of 30 μm or less from the discharge nozzle are contained in the liquid tank. A micro bubbling device that generates a liquid composition containing microbubbles by discharging is preferable.

  The above micro bubbling apparatus is of a pressure dissolution type, but is advantageous in terms of cost performance and suitable for the generation of microbubbles in the present invention.

  Here, in particular, “characteristics of microbubbles” such as the particle size distribution of microbubbles of microbubbles may be sensitive to carbon dioxide absorption by plants. In order to adaptively change the “characteristics of the microbubbles” such as the particle size distribution of the microbubbles, the method and apparatus for variable speed control of the vortex pump motor disclosed in Patent Document 6 can be used. The change in the “characteristics of the microbubbles” can be grasped by detecting the optical characteristics of the liquid in the liquid tank, for example, by detecting turbidity.

  As a reference, the device claim of claim 6 of Patent Document 6 is transcribed.

  (Patent Document 6 Claim 6) In an apparatus for generating microbubbles in a liquid, a sensor for detecting the optical characteristics of the liquid in the liquid tank is provided, and an AC motor for rotating the impeller built in the vortex pump is provided. The apparatus further comprises means for variably controlling the number of revolutions, and further comprises control means for controlling the number of revolutions of the AC motor that rotates the impeller of the eddy current pump based on the optical characteristic signal of the liquid that is the output of the sensor. A device that generates microbubbles in a liquid.

  Furthermore, in the carbon dioxide-containing microbubble described here, it is preferable to add a plant activation promoting substance to the liquid in the vicinity or the liquid in the mist because a synergistic effect is obtained. “Drip” for weakened plants.

  In other words, not only carbon dioxide but also oxygen for breathing (O2) and minerals such as potassium and calcium ions involved in plant hormones are "drops" in the liquid phase of water or mist containing microbubbles or bubbles. It can also be added as an effect promoter.

  The amount of minerals such as oxygen (O2) for respiration and potassium and calcium ions involved in plant hormones is also appropriately determined according to the plant species and their state, as in the case of the carbon dioxide concentration “B”. It can be determined experimentally.

  Furthermore, in the present carbon dioxide-containing microbubble, in the present carbon dioxide-containing microbubble, gas components other than carbon dioxide, specifically nitrogen (N2) component, oxygen (O2) If the component has a specific component ratio different from that of the atmosphere, the plant may be stimulated and carbon dioxide absorption may be promoted.

  This specific component ratio is also different in accordance with the plant species and their state, so it cannot be generally stated, but it is often effective for promoting carbon dioxide absorption.

  For example, when nitrogen is at a high concentration of 80-90%, the plant feels the threat of depletion and tries to leave offspring (seed and fruits). Absorption has been reported.

  FIG. 6 shows the adjustment of the nitrogen (N2) component, oxygen (O2) component other than carbon dioxide, the adjustment of the amount of minerals such as potassium and calcium ions involved in the plant hormone, and the liquid that E4 sucks. It is added to this proposal that carbon dioxide absorption is assisted by adjusting environmental indicators such as temperature, pressure, hydrogen ion concentration, biological / chemical oxygen demand of (water) liquid tank. A schematic diagram of a preferred system is shown.

  In the auxiliary promotion system of FIG. 6, the method and apparatus for generating heat during the bubbling described in Patent Document 7 can be used for increasing the temperature for controlling the temperature.

  That is, when discharging microbubbles from the discharge nozzle into the liquid in the liquid tank, a means for changing the suction load may be provided at the suction end of the liquid suction means.

  For reference, the device claim of claim 1 of Patent Document 7 is transcribed.

  (Patent Document 7) Claim 1 comprises a vortex pump in which a gas suction means, a liquid suction means, and a liquid discharge means are connected, and the liquid suction means draws the liquid in the liquid tank while the gas suction means sucks the gas. A device for generating microbubbles in the liquid in the liquid tank by suction, wherein the vortex pump rotates a built-in impeller with a motor, and the microbubbles generate microbubbles having a particle size of 30 μm or less. An apparatus for generating heat by generating microbubbles in the liquid, wherein means for changing the suction load is provided at the suction end of the liquid suction means.

  For the block elements in FIG. 6, please refer to the section “Brief description of the drawings”. If a part of such an auxiliary carbon dioxide absorption promotion mode is defined as a subclaim, for example, it is as follows.

  E4 is a mode that combines means for adjusting the amount of minerals such as potassium and calcium ions involved in plant hormones in the liquid to be sucked, and also has means for assisting in carbon dioxide absorption. .

  E4 has both a gas source of gas components other than carbon dioxide and a means for adjusting the gas component of the microbubbles, and the gas component of the microbubbles adjusts the carbon dioxide component to a concentration “B” while other gases. It is an aspect that combines means to change the ingredients and promote it as an assistant.

E4 has a means to adjust the environmental index amount such as temperature, pressure, hydrogen ion concentration, biological / chemical oxygen demand in the liquid to be sucked, and a means to assist carbon dioxide absorption in a supplemental manner. It must be a mode that combines.

  According to the present invention, (1) carbon dioxide gas fixation is promoted and greenhouse gas emissions are reduced, which can help prevent global warming. (2) carbon dioxide gas generated by combustion or the like can be assimilated by carbon dioxide assimilation. It is converted into carbohydrates and converted to food, which helps solve food problems.
