Description

Oxygen Water Production Equipment {An Apparatus for Producing Water having High Density of Oxygen}

The present invention relates to an oxygen water production apparatus, and more particularly to an oxygen water production apparatus capable of containing a high concentration of oxygen in water.

Oxygen water refers to water in which the amount of oxygen dissolved (ie dissolved oxygen) is greater than the average average dissolved oxygen (approximately 7 ppm at room temperature in air). As mentioned above, such oxygen water is beneficial to plants, animals or humans because the amount of oxygen contained in the water is higher than that of ordinary water.

For example, supplying oxygen water to a fishbowl or aquaculture farms not only contributes to the growth of fish growing in a fishbowl or aquaculture farms, but also purifies water that contains feces or other suspended solids as they grow. There is an advantage that can proceed faster by a high concentration of oxygen.

In addition, the use of oxygen water for plant cultivation, the Agricultural Research Institute's research shows that the yield of agricultural products according to plant cultivation increases by more than 10% than when supplying general agricultural water.

In addition, when oxygen water is used as drinking water, oxygen can be supplied to the body even through water, so it may be helpful to the elderly, who are uncomfortable breathing through the respiratory system.

Therefore, there is a need to actively expand the oxygen water such as fishery (especially aquaculture) and agriculture.

On the other hand, this advantageous oxygen water production apparatus produces oxygen water in two ways. One is to produce oxygen water by using an electrolysis method, and the other is to produce oxygen water by simultaneously pressurizing water and oxygen to a plurality of partitions in which fine pores are formed.

However, the oxygen water production apparatus using the former method is expensive to manufacture and install, there is a problem that the generated oxygen is generated in the form of bubbles rather than dissolved in the water disappears into the atmosphere.

In addition, the oxygen water producing apparatus using the latter method has an advantage of obtaining a relatively high concentration of dissolved oxygen, but requires a considerably high pressure to increase the concentration of oxygen. In addition, the latter oxygen water production apparatus has a problem that the dissolved oxygen amount of the produced oxygen water is rapidly dropped in the atmosphere (see FIG. 9), it is difficult to be utilized in farms or agricultural products growers that require a large amount of oxygen water.

The present invention is to solve the above problems, it is an object of the present invention to provide an oxygen water production apparatus capable of producing oxygen water containing a relatively small amount of dissolved oxygen change with time while containing a high concentration of dissolved oxygen.

Preferably, the first rotating body and the second rotating body are respectively installed in succession of two or more sheets, and the first fixing body and the second fixing body are each of the first rotating body and the second rotating body. It is preferable to be installed in the case so as to correspond to the entire installation position.

The first rotating body, the second rotating body, the first fixing body, and the second fixing body may be disposed so that protrusions of adjacent members are shifted from each other.

In addition, the cover may be further provided with a gas micronization means to generate bubbles when mixing the liquid flowing through the first inlet and the gas flowing through the second inlet.

In addition, the gas atomization means is preferably a filter member provided in the second inlet.

Oxygen water production apparatus of the present invention has the advantage that can produce a high concentration of oxygen water through a relatively simple structure.

In addition, the oxygen water production apparatus of the present invention is not only possible to continuously produce the oxygen water, but also change the amount of dissolved oxygen of the oxygen water by changing the arrangement and arrangement number of the rotating body and the fixed body therein, It can be used in large farms or large agricultural fields that require high oxygen and high concentrations of oxygen.

As a result of the experiment, as shown in FIG. 7, when the oxygen supply amount was increased to about 200 kPa / min, the dissolved oxygen amount increased relatively rapidly to about 31 ppm, but when the oxygen supply amount was increased to 300 kPa / min or more. There was no significant increase in dissolved oxygen.

Applicants have found that the desired oxygen supply for 20 L / min of water is 300 kW / min through this experiment.

2. Relationship between Internal Pressure and Dissolved Oxygen

Applicants, in order to determine the correlation between the internal pressure and the dissolved oxygen amount of the oxygen water production apparatus of the present invention, two methods (the first method is to change the water supply amount, the second method is to open the opening 114 of the outlet 114) To adjust the internal pressure of the oxygen production apparatus.

As a result of the experiment, as shown in FIG. 8, the amount of dissolved oxygen was generally proportional to the internal pressure of the oxygen water production apparatus, but the change slope was not so large. Applicants have therefore found that the pressure increase could be one of the ways to increase dissolved oxygen, but this method is not very effective.

3. Relationship between the number of oxygen water generators and the amount of dissolved oxygen

Applicants have tried to connect the oxygen water production equipment under the same operating conditions in series in order to find out the correlation between the number of oxygen in the oxygen production apparatus and the dissolved oxygen amount in series. Table 1 shows the experimental results.

As a result, when the number of series connections of oxygen water production equipment was increased from 1 to 3 units, the amount of dissolved oxygen was generally increased proportionally, although the size of dissolved oxygen was largely increased, but the increase in dissolved oxygen amount was enjoyed more than 4 units. Could know.

Therefore, the applicant has found that the ideal number of series connections of the oxygen water production apparatus does not exceed three, and the increase rate of the number of series connections and the amount of dissolved oxygen according to this experiment is not so large.

4. Relationship between oxygen water storage period and dissolved oxygen content

Applicant has left the oxygen water produced by the oxygen water production apparatus of the present invention and the conventional oxygen water production apparatus for several days in the air in order to grasp the correlation between the storage time of the oxygen water and the dissolved oxygen amount.

As a result, as shown in FIG. 9, the dissolved oxygen content of the oxygen water produced by the conventional oxygen water production apparatus was rapidly decreased in about one day (about 60%), and after about five days, the dissolved oxygen content of the conventional water was (About 7 ppm). On the other hand, the dissolved oxygen amount of the oxygen water produced by the oxygen water production apparatus of the present invention was reduced by about 20% the next day, and decreased by about 50% on the fifth day.

Through this experiment, it was found that the oxygen water production device of the present invention lasted longer than the conventional oxygen water production device, but the storage period of oxygen water (ideally 5 days) was not very long. Was done.

5. Relationship between Rotational Speed and Dissolved Oxygen

Applicant tried to change the rotation speed of the rotating shaft 130 through the drive means in order to grasp the correlation between the rotation speed and the dissolved oxygen amount of the oxygen water production apparatus of the present invention.

As a result, as shown in FIG. 10, it was found that the amount of dissolved oxygen in the water began to increase significantly at 2500 rpm and increased rapidly at around 3500 rpm. However, when the rotating shaft 130 is rotated at an excessively high speed, water vapor is generated by friction between water and the rotating body, and therefore, it is preferable to rotate in the range of 3000 to 4000 rpm.

The above-mentioned experimental results are all operating conditions for optimizing the oxygen water producing apparatus of the present invention, but the characteristics of the present invention are not particularly limited, but the oxygen water producing apparatus of the present invention and the conventional oxygen water producing apparatus clearly It can be used as a distinguishing factor.
