The pressure vessel 1 according to the present invention includes an upper cap 3 integrally formed on the upper surface of the body 2 and the body, a lower cap 4 integrally formed on the lower surface of the body 2, and an upper cap 3. The outer cylinder 5 integrally formed on the bottom surface of the lower cap 4 and spaced apart from the upper surface of the lower cap 4, and integrally formed on the upper surface of the lower cap 4 and inserted into the outer cylinder 5 described above. An inner cylinder 6 spaced apart from an inner surface and spaced apart from a bottom surface of the upper cap 3, mounted in the center of the upper cap 3 described above, inserted into an inner surface of the inner cylinder 6 described above, and spaced apart from the inner cylinder 6; An inlet 7 spaced apart from the upper surface of the lower cap 4, a drain port 10 formed on one side of the body 2, and a drain formed in the lower cap 4 and disposed inside the inner cylinder 6; It consists of a part 12.

The outlet 10 described above has an outlet inlet 11 formed between the outer cylinder 5 and the body 2.

The outlet inlet 11 described above is preferably directed downward, and for this reason, bubbles are more likely to be discharged more smoothly because they have a rising property.

In particular, the inner diameter of the outlet 10 is preferably smaller than the inner diameter of the inlet 8, and for this reason, the pressure is a force acting per unit area, and the cross-sectional area of the outlet 10 is greater than that of the inlet 8. It is so small that it produces a pressure difference.

In addition, the outlet 10 described above may form a small inner diameter of the outlet 10 by inserting the bushing member 11a into the outlet 10 as shown in FIG. 3.

By inserting the bushing member 11a, it is possible to work more easily by manufacturing the same size when manufacturing the inlet 8 or the outlet 10, and inserting the bushing member 11a into the outlet 10 more easily. Can be reduced.

In addition, the outlet 10 described above can reduce the cross-sectional area that is drained by the source by forming the discharge hole (11b) on one side of the body 2, as shown in Figure 4, the cross-sectional area of the inlet 8 by reducing the cross-sectional area The difference between the two causes pressure difference.

In addition, although not specifically shown, the outlet 10 may be further equipped with a valve that can reduce or increase the cross-sectional area through which the fluid flows, and such a valve is used for a commercial valve, a detailed description thereof will be omitted.

That is, the pressure can be adjusted by operating the commercial valve.

The drain 12 is equipped with a drain valve 30 to control drain drainage.

In addition, a pressure gauge connecting socket 13 is formed on one side of the upper cap 3 so that the pressure gauge can be mounted, and a pressure valve connecting socket 14 is formed to allow the pressure valve to be mounted.

The pressure gauge and the pressure valve described above are equipped with a commercial product, and a detailed description thereof will be omitted.

The pressure gauge described above makes it possible to easily grasp the internal pressure of the pressure vessel 1, and when the pressure rises above the abnormal pressure, it is possible to open and close the pressure valve to take safety measures.

In addition, the pressure valve may be automatically opened when the pressure rises higher than the set pressure to lower the pressure.

In addition, the one side of the body (2) is formed by separating the entry and exit port 15 and the other entry and exit port 16 in the vertical direction, and transparent see-through portion 18 between the entry and exit ports (15, 16) Form a so that you can visually check the water level.

In addition, a plurality of support bases 17 are formed in the lower portion of the body 2 to support the pressure vessel (1).

In the pressure vessel 1 according to the present invention, as shown in FIG. 5, the water inlet 8 is connected to a water pump 20, and the water pump 20 is connected to a water supply pipe to form a water supply 23.

In addition, the air mixing unit 21 and the oxygen generator 22 may be further mounted on one side of the water supply pipe.

The above-described air mixing unit 21 is intended to allow the flow of general outdoor air.

In this way, the introduction of general outside air is to continuously supply air even when the oxygen generator fails or fails to function due to an unexpected cause.

The above-described oxygen generator 22 generates oxygen in itself to inject oxygen into the water pump 20.

Although not shown, a check valve may be installed at one side of the inlet of the water pump to prevent the pressure from being lowered or leaking.

Hereinafter, the operation and operation of the present invention will be described with reference to the accompanying drawings.

Initially, any one of the air mixer 21 and the oxygen generator 22 may be selectively opened or closed.

In addition, the drain valve 30 starts to operate in a closed state.

For example, when the water pump 20 is operated while the air mixing unit 21 is opened and the oxygen generator 22 is stopped, water and outdoor air are mixed and introduced into the water pump 20, and the water pump ( 20) sends a mixture of water and air to the pressure vessel (1).

In addition, when the water pump 20 is operated while the air mixing unit 21 is closed and the oxygen generator 22 is operated, water and oxygen generated artificially are mixed and introduced into the water pump 20, and the water pump 20 sends a fluid mixed with water and oxygen to the pressure vessel (1).

Water is injected into the pressure vessel (1) through the mouth (7) and filled in the inner cylinder (6), the water filled in the inner cylinder (6) overflows the inner cylinder (6) and pours into the interior of the outer cylinder (5) to the body (2) It gets kicked up inside.

It is then drained through the outlet 10.

In particular, there is a difference in the cross-sectional area of the inlet 8 and the drainage cross-sectional area of the outlet 10, the pressure difference occurs and the pressure generated in this way is pressurized to the water inside the pressure vessel (1).

When water is pressurized, the water is contained in the water and the incoming air is transformed into microbubbles and the molecular size of the water is split.

In more detail, the human eye can think of water as a single fluid, but when external force is applied to the water, the water's cohesion weakens as the object breaks.

Therefore, when high pressure pressure is applied to the water, ultra-fine bubbles are generated and the water becomes cloudy as milk.

That is, the water drained through the drain 10 has a milky color, which means that the microbubbles are contained in a large amount in the water.

In addition, when the internal pressure of the pressure vessel 1 rises, the pressure is displayed on the pressure gauge and the pressure is adjusted to operate stably within the safety range.

In addition, the water level in the pressure vessel (1) is confirmed through the see-through section (18).

On the other hand, the flow rate of the effluent water discharged through the outlet 10 is inversely related to the pressure of the pressure vessel 1, and when the pressure is high, the flow rate of the effluent water decreases, and when the pressure is low, the flow rate of the effluent water increases.

On the other hand, the water flowing into the pressure vessel (1) is naturally introduced into the water passing through the filter, but due to an unexpected cause, residues or debris are introduced together, and the debris is discharged through the drain portion 12. .

In order to drain, when the drain valve 30 is opened, the debris accumulated in the inner cylinder 6 is discharged to the outside.

Hereinafter, the characteristics of the water generated using the pressure vessel 1 according to the present invention will be described in detail with reference to FIGS. 6 to 9.

Figure 6 is a measurement of the change in dissolved oxygen and compares the use of the pressure vessel (1) according to the present invention and when using only a general oxygen supply device.

The general oxygen supply device uses a method of increasing dissolved oxygen (DO) concentration by abandoning the air in the atmosphere through the acid pipe.

However, this method has a drawback that the contact area decreases depending on the bubble size and the oxygen transfer efficiency is very low, so that the dissolution rate of oxygen cannot be increased. After performing a general aeration for 5 minutes, the concentration of dissolved oxygen was examined with time. It can be seen that the trend is greatly reduced.

On the other hand, in the case of the effluent produced by mounting the pressure vessel 1 according to the present invention, DO is saturated even after the bubbles disappear, and the rate of decrease of the dissolved oxygen concentration with time is also slower than that of the general aeration.

Figure 7 is a measurement of the dissolved oxygen change by the oxygen dissolver is a comparison between the use of the pressure vessel (1) according to the present invention and the use of a general oxygen supply device.

As a method for artificially increasing the dissolved oxygen concentration of water, a method of increasing the dissolved oxygen concentration by using a pure oxygen or an oxygen generator to give up a high concentration of oxygen through an acid pipe is used.

After aeration of 3 liters (L) per minute using an oxygen generator in general for 1 minute, the concentration of dissolved oxygen and the pressure vessel (1) according to the present invention were aerated for the same time, and then the dissolved oxygen was compared. 5 times higher.

In addition, the result of measuring DO change by standing still showed that dissolved oxygen by oxygen dissolving agent showed 11.2mg / L after 1 hour, whereas it decreased to 10.1mg / L level in 2 minutes by normal acid organ. Appeared.

Accompanying drawings Figure 8 is a data analysis of the ultra-miniature fork size in the effluent generated by applying the pressure vessel (1) according to the present invention, Figure 9 is a data analysis of the ultra-miniature fork generated by the general electrolytic method.

In order to analyze and compare the size of microbubbles, a particle size analyzer (Melvern Inc./MAM5020) was used to compare the size of bubbles generated by electrolysis.

In both cases, the average bubble size did not show a big difference, but when looking at the distribution of bubble sizes, it was found that the microbubbles in the effluent produced by applying the pressure vessel 1 according to the present invention had a more uniform size distribution.

The commonly used electrolytic method is pointed out the disadvantages of high power consumption and electrode contamination, when applying the pressure vessel (1) according to the present invention can generate the same bubble at a low cost, the oxygen by the pressure of the water pump The higher the dissolution rate, the better the dissolved oxygen concentration can be seen.

In addition, a comparative experiment was conducted to measure the amount of oxygen remaining, and the test results were analyzed according to the water quality test method (2005.2).

<Comparative Example 2>

<Comparative Example 3>

<Invention>

As can be seen from the above experimental results, it can be seen that the effluent produced by applying the pressure vessel 1 according to the present invention has a high residual amount of oxygen.

To explain this in more detail, look at how much oxygen per liter is present after 5 minutes have elapsed for the effluents generated in each of the same comparative examples.

In Comparative Example 1, the treated water was tested in a general aeration, and immediately after the outflow, it was 8.0 mg / L, and after 5 minutes, it was lowered to 4.8 g / L.

In Comparative Example 2, a general microbubble of water was tested, and it was 9.2 mg / L immediately after the outflow and decreased to 6.8 mg / L after 5 minutes.

In Comparative Example 3, the water treated with the general aeration by the oxygen generator was tested, and it was excellent at 18.2 mg / L immediately after the outflow, decreased to 7.9 mg / L after 5 minutes, and 5.8 mg / L after 1 hour. Lowered to L.

On the contrary, using the pressure vessel (1) according to the present invention and experimenting with water treated with general aeration, it was very good at 89.6 mg / L immediately after the outflow, and after 3 minutes, the remaining amount was excellent at 38.0 mg / L. It was 11.2mg / L even after 1 hour.

In other words, the use of the pressure vessel (1) according to the present invention was able to obtain a very good result compared to the conventionally generated treated water in the production of fine bubbles and dissolved oxygen.

Hereinafter will be described the application field of the pressure vessel (1) according to the present invention.

Example 1-Household

It can be used when taking a bath at home, and these ultra-foam bubbles are released and ultrasonic waves and negative ions in the process of creating and disappearing, and these characteristics are used for cleaning, sterilization, massage, diet, and stress relief.

In other words, ultra-mini-foam can clean old wastes in pores without skin irritation due to soap or bath towel, and because of its size, micro-foams are smaller than pores. The waste is positive and the waste is reacted with water and the waste, and the waste is separated from the pores and washed.

For reference, the size of the skin pores is 0.02mm ~ 0.05mm, ultra-micropore foam is 0.002 ~ 0.0002mm.

In addition, the pores and capillaries of the body surface are extended to transmit the warmth to the deeper parts of the body, so that the warm temperature of the bath water is more effectively transmitted to the body, thereby obtaining synergistic effects such as the warming effect.

In addition, when the ultra-mini-foam wraps the skin, blood circulation is promoted and skin cells are activated, so a massage effect can be expected.

In addition, the water turns milky and flows out, giving you a visual feeling as if you are taking a hot spring bath.

On the other hand, anionic effluents and cationic effluents or reactions react with each other to synthesize each other. have.

For example, when washing vegetables and fruits, residual pesticides can be removed cleanly, and bathing can be easily done without using shampoo or soap in bathing the dog, and cleans / sterilizes toys and the like to remove toxins from the toys. Can be removed.

In the fishery sector, more abundant oxygen can be supplied to the tanks during aquaculture, thereby eliminating the problem of fish waste being killed due to lack of oxygen.

In addition, in the field of water quality improvement, sludge and pollutants in sewage treatment plants can be effectively removed.

Although the invention has been described in detail only with respect to the specific examples described, it will be apparent to those skilled in the art that various modifications and variations are possible within the spirit of the invention, and such modifications and variations belong to the appended claims.

The pressure vessel according to the present invention can dissolve more oxygen in the water, and also produce ultra-miniature bubbles in the water, and can effectively use the net function of the anion generated in the process of generating and disappearing ultra-miniature bubbles.

In particular, by sufficiently dissolving oxygen in water, it is possible to prevent the death of fish and shellfish oxygen due to the lack of oxygen in fish and shellfish culture.

In addition, due to the additionally generated negative ions and very small ultra-small size gun can be expected to the effect of cleaning and washing in various fields.
