Description

  The present invention relates to a high-concentration oxygen water generator that generates water with a high oxygen concentration suitable for crop growth.

  In general, to make good crops, it is necessary to make soil with sufficient oxygen, good water rich in oxygen, and well-balanced nitrogen, phosphoric acid, potash and trace elements.

  In addition, the nutrient absorption of crops is closely related to the concentration of nutrients in the soil solution present around the roots. If a particular nutrient is present at a too low concentration, the crop will not be able to absorb not only that nutrient but also other nutrients and growth will be suppressed.

  The body components of crops are mostly oxygen, hydrogen, and carbon, and these components account for about 94% of the total. Carbon is stored as an organic substance made from carbon dioxide in the air by photosynthesis. Therefore, crops are taking about 94% of their constituents from water and air other than fertilizer.

  When groundwater is used as agricultural water, harmful reducing substances such as divalent iron ions may be dissolved. If these harmful reducing substances are dissolved in groundwater, they will take away oxygen in the soil and form iron oxide, promote oxygen deficiency, and combine with iron and phosphoric acid to inactivate phosphoric acid. It becomes impossible to absorb the phosphoric acid in it, causing the nutrient balance in the crop to be lost. Therefore, obtaining agricultural water with good water quality has been an issue.

As a solution to this problem, there is a swirl type fine bubble generator as shown in Japanese Patent No. 3397154. The swirl type fine bubble generator is provided at a container body having a conical space, a liquid inlet opening in a tangential direction in a part of the inner wall circumferential surface of the space, and a bottom portion of the space. It is comprised from the gas introduction hole and the turning outlet port opened at the top of the space.
Japanese Patent No. 3397154

  However, in the conventional swirl type fine bubble generator described above, since the gas is mixed with the liquid in the conical narrow space, the bubble becomes coarse and is ejected, so that the contact area between the liquid to be processed and the bubble is sufficient. There was a problem that the amount of dissolved oxygen and the reaction efficiency could not be increased.

  In addition, since liquid and gas are mixed in a conical space, there is a limit to supplying a large amount of gas, and it is difficult to control the mixing ratio of liquid and gas to a predetermined value. There was also a problem that the pressure in the conical space fluctuated during on / off, the liquid flowed back to the gas introduction hole, and the gas introduction hole was easily clogged with solid matter mixed in the liquid, and continuous operation was not possible. .

  Therefore, the present invention has been made in view of the above-described conventional problems, and can generate fine bubbles having a very large gas-liquid contact area in the liquid of a gas-liquid reaction tank in agricultural water such as a water storage tank. High concentration that can significantly increase the amount of oxygen, suppress anaerobic bacteria, increase useful aerobic microorganisms, promote soil agglomeration and nutrients, and supply agricultural water that is extremely effective for crop growth An oxygen water generator is provided.

  A high-concentration oxygen water generating apparatus according to the present invention includes an apparatus main body that is installed in water and generates fine bubbles, an air pump that supplies gas to the apparatus main body, a controller that controls the apparatus main body and the air pump, The apparatus main body is installed at the bottom of a case in which a large number of holes are formed to supply a submersible pump for supplying water, a microbubble generator for generating microbubbles, the submersible pump and the microbubble generation A gas pipe that supplies a gas from the air pump is connected to the liquid pipe via a check valve, thereby solving the above-described problem.

  The present invention also includes an apparatus main body that is installed in water and generates fine bubbles, an air pump that supplies gas to the apparatus main body, and a controller that controls the apparatus main body and the air pump. The main body is a submersible pump that is installed at the bottom of a case in which a large number of holes are formed and supplies water, a microbubble generator that generates microbubbles, and a liquid pipe that connects the submersible pump and the microbubble generator And a plurality of the fine bubble generators are arranged around the submersible pump, thereby solving the same problem as described above.

  Furthermore, the present invention includes an apparatus main body that is installed in water and generates fine bubbles, an air pump that supplies gas to the apparatus main body, and a controller that controls the apparatus main body and the air pump, The main body is a submersible pump that is installed at the bottom of a case in which a large number of holes are formed and supplies water, a microbubble generator that generates microbubbles, and a liquid pipe that connects the submersible pump and the microbubble generator A gas pipe for supplying gas from the air pump is connected to the liquid pipe in the middle of the liquid pipe via a check valve, and the controller is configured to start a predetermined time after starting the air pump at the time of starting. The above-mentioned problem was solved by starting the submersible pump after the passage.

  The fine bubble generator according to the present invention includes a container body having a conical space, a pressurized gas-liquid introduction port opened in a tangential direction to a part of an inner wall surface of the conical space, and the cone. A gas bubble vortex tube that is formed in a conical space and is formed to form a gas vortex tube that is swept out and tapered while forming a gas vortex tube. The above-mentioned problem was solved by generating a fine bubble by forcibly cutting the gas vortex tube by generating a swirl speed difference before and after the tube.

  In the high-concentration oxygen water generating apparatus configured as described above, since the fine bubbles ejected from the fine bubble generator into the water tank increase the contact area between the gas and the liquid, the amount of dissolved oxygen contained in the water is reduced. It can be increased to make water rich in active oxygen.

  When this water is given to crops, it suppresses anaerobic bacteria in the soil, increases the number of effective aerobic microorganisms, and promotes soil agglomeration and effective nutrients, so it has the excellent effect of improving crop growth. It is what you play.

FIG. 6 is a partially broken perspective view showing the configuration of the controller used in the high-concentration oxygen water generating device of FIG. 1, and FIG. 7 is another configuration of the high-concentration oxygen water generating device. FIG. 8 is an explanatory view showing a usage state of the high-concentration oxygen water generator.

  As shown in FIG. 1, the high-concentration oxygen water generating apparatus according to the present invention is installed in, for example, an aquarium 1 for agricultural water or the like. The apparatus main body 10 and a controller 30 for controlling the air pump 20 are configured. The apparatus main body 10 and the compressor (20) are a gas pipe 21 and a liquid pipe 14 via a check valve 22. It is connected to.

  As shown in FIGS. 2 and 3, the apparatus main body 10 of this high concentration oxygen water generating apparatus is installed in a case 11 in which a large number of holes are formed and supplies a submerged pump 12 for supplying water and fine bubbles. A fine bubble generator 13 that generates the liquid pipe 14 that connects the submersible pump 12 and the fine bubble generator 13 is provided. A gas pipe 21 for supplying gas from the air pump 20 is connected to the liquid pipe 14 via a check valve 22, and four fine bubble generators 13 are arranged around the submersible pump 12. . The gas main body 10 can be made compact without reducing the flow rate by making the gas 14 rectangular and vertical.

  As shown in FIG. 2, the case 11 of the apparatus main body 10 is formed in a hexagonal column from a highly durable material such as stainless steel, and has a large number of walls so that water can freely enter and exit the six-sided walls. Holes 11a1, 11a1, 11a1, 11a2, 11a2, 11a2, 11b1, 11b1, 11b1,... Are formed. A submersible pump 12 and a fine bubble generator 13 are installed at the bottom, and a detachable lid 11b is attached to the top. The lid 11b is provided with a handle 11c for carrying the apparatus main body 10.

  As shown in FIG. 4, the fine bubble generator 13 used in this water purification apparatus includes a container body 13 a having a conical space and a part of the inner wall surface of the conical space in a tangential direction. There are provided a pressurized gas-liquid inlet 13b and swirl gas-liquid outlets 13c and 13c opened at the tops on both sides of the conical space. As shown in FIG. 5, the shape of the swirling gas / liquid outlets 13c and 13c is formed in a funnel shape opened to the outside, and the opening angle is 65 to 65 so that the swirling gas / liquid can be ejected most efficiently. It is formed at an angle of 130 °. Further, on both sides of the conical surface of the container body 13a, cap support portions 13d, 13d, 13d,.

  As shown in FIG. 5, the fine bubble generator 13 configured as described above is a gas-liquid mixture in which gas and liquid are mixed and pressurized through a liquid pipe 14 from a pressurized gas-liquid inlet 13b in a tangential direction. When the fluid flows in at a high pressure, the fluid turns along the inner wall surface of the container body 13a and moves to the turning gas-liquid outlets 13c and 13c while being vigorously gas-liquid mixed. At this time, due to the difference in specific gravity between the liquid and the gas, centrifugal force acts on the liquid, centripetal force acts on the gas, and a negative pressure axis V is formed near the central axis of the container body 13a. Due to the generation of the negative pressure axis V, a force is exerted to suck the liquid outside the container body 13a in the vicinity of the center of the swirling gas-liquid outlets 13c, 13c.

  On the other hand, the gas-liquid mixed fluid in the container main body 13a is swung along the inner wall surface of the container main body 13a, and the inner wall surface of the container main body 13a is narrowed as it approaches the swirling gas-liquid outlets 13c, 13c. Becomes faster, becomes the fastest in the vicinity of the swirling gas-liquid outlets 13c, 13c, and presses against the negative pressure liquid. Therefore, the gas collected in the vicinity of the negative pressure axis V passes while being compressed and sheared between the gas-liquid mixed fluid ejected while swirling at the swirling gas-liquid outlets 13c and 13c. The fine gas bubbles are ejected to the outside from the swirling gas-liquid outlets 13c and 13c.

  Next, the controller 30 that controls the operation of the high-concentration oxygen water generator configured as described above will be described with reference to FIG. The controller 30 houses the air pump 20 inside a box-shaped case 31. A main power switch 33, a power lamp 34, an air extraction coupler 35, a pump operation lamp 36, a pressure gauge 37, an air amount adjustment knob 38, and an outlet 39 for the submersible pump 12 are attached to the front panel 32 of the controller 30. Yes. A check valve 22 is attached between the air pump 20 and the air extraction coupler 35.

  The main power switch 33 is a switch that activates the controller 30 of the high-concentration oxygen water generator, and when activated, the power lamp 34 is lit. When the submersible pump 12 is operated, the pump operation lamp 36 is turned on, and the pressure gauge 37 indicates a pressure scale. The air amount adjustment knob 38 adjusts the pressure gauge 37, and is adjusted so that the controller 30 is started at 700 ml / min and the submersible pump 12 is operated at 300 ml / min. .

  When the submersible pump 12 operates earlier when the high-concentration oxygen water generator is started, the controller 30 has a stronger water pressure than the inflow pressure of the air pump 20, and therefore the check valve 22 of the gas pipe 21. Air is not sent to the submersible pump 12 side, and the device does not work well. In order to prevent this, the air pump 20 operates quickly after the main power switch 33 is turned on, and then the liquid pipe 14 operates. An appropriate time difference between the air pump 20 and the submersible pump 12 is about 45 seconds, and this time is set by a timer mechanism (not shown).

  In the high-concentration oxygen water generator configured as described above, the fine bubbles ejected from the fine bubble generator 13 into the water tank 1 increase the contact area between the gas and the liquid, so that dissolved oxygen contained in the water The amount can be increased to water with high active oxygen. When this water is given to the crop, the anaerobic bacteria in the soil are suppressed, effective aerobic microorganisms are increased, and the soil is aggregated and the nutrients are promoted, so that the growth of the crop is improved.

  Further, since this water has a small cluster (water molecule group) of 10 to 30 μm, it easily penetrates into the tissue cells of the crop, and promotes the biochemical reaction to help the growth. And since a surface tension will become small if a cluster becomes small, there exists a surface active effect | action, adhesion and absorption of agrochemicals etc. will improve, and the usage-amount of agrochemical can also be reduced.

This high-concentration oxygen water generator is a large-scale high-concentration oxygen water generator installed on land. This high-concentration oxygen water generator is installed in a sealed hexagonal stainless steel tank 19, and four microbubble generators 13 are arranged in a cross shape in a socket 23 connected to a pipe 18. It is set. High-concentration oxygen water generated by the fine bubble generator 13 is supplied to the outside through a hose 24. The controller 30 is installed in the vicinity of the inlet of the tank 19 through the check valve 22, and the time difference built-in timer can be set for one hour or more depending on the head and distance of the water source pond.

  As shown in FIG. 8, the high-concentration oxygen water generator configured in this way is mainly installed outdoors, and after pumping up water from a pond or a reservoir with a hose 17, the pump is passed through a filter 15. At 16, the pipe 18 is supplied to the high-concentration oxygen water generator. And it supplies to a water storage tank etc. with the hose 24, and is used for watering etc. of a field. In golf courses and the like, it is also possible to activate the water in the pond by circulating high-concentration oxygen water as a countermeasure against blue sea bream generated in the pond.
