い。<Conventional technology> Conventionally, as a mixer for supplying and dissolving a gas in a flow path of a liquid L, as shown in FIG. 2 (A), a gas nozzle is opened at a squeezed portion of a Venturi tube to form a gas (G). Orifice type for supplying gas to the narrowed portion at the tip of the center nozzle of the orifice type as shown in FIG. (B), and a gas nozzle simply inserted into the flow pipe as shown in FIG. A nozzle insertion type or the like is known, and in many cases, the entire mixer is integrally formed.

は殆ど使用できないという問題がある。<Problems to be Solved by the Invention> However, in the conventional mixer as described above, the mixing property of gas and liquid is extremely poor. For example, when ozone gas is dissolved in water, the dissolution rate at that temperature is 45 %, And the above-mentioned Venturi-type mixer has the drawback that it requires an ozone supply pressure higher than the feed water pressure (about 2 kg / cm 2 ). Generally, 0.5 kg / cm is required for generation and supply of ozone. There is a problem that it can hardly be used under circumstances where it is desirable that the number is 2 or less.

る。Further, in the orifice type mixer, there is a problem that the pressure loss of feed water is large and the water pressure downstream of the orifice type nozzle is reduced by about half. Further, the mixer of the nozzle insertion type has the drawbacks that the ozone bubbles to be supplied are too large to further reduce the mixing ratio and that the highest ozone supply pressure is required.

The method and apparatus disclosed in Japanese Patent Publication No. 24 are used to stably set the flow rate and pressure of high-concentration oxygen that adsorbs, separates and concentrates air in the atmosphere, and adjusts the applied voltage or frequency thereto. As a result, ozone having a required ozone concentration (ozone having a maximum concentration of about 95% can be stably obtained) is obtained. Subsequently, ozone is mixed with water by a mixing / separating device described below, etc., and the dissolved ozone concentration is set efficiently to obtain stable active ozone water.

る旋回室17を有している。The device for obtaining the ozone water will be described. The high-concentration ozone is mixed and mixed as shown in FIG.
It is mixed with water by a separator and separated into bubbles to be used as safe ozone water. The mixer 11 is formed by concentrically screw-connecting a sleeve-shaped nozzle body 12 and a mixing sleeve 13 to each other. The outer periphery of the base end of the nozzle body 12 forms a screw joint 16 with a water supply pipe 14, and The side has a swirl chamber 17 composed of a space (hole) having a relatively large diameter.

い旋回流に整えられ、細い直線状の旋回流となる。A spiral body 18 having substantially the same diameter as the swirl chamber and forming a spiral of about 1 to 2 pitches is accommodated in the swirl chamber 17 and supplied at a pressure of, for example, about 2 kg / cm 2 from the water supply pipe 14 side. It is a mechanism that instantaneously converts the flow of water into a swirling flow.
At the front center of the swirl chamber 17, a nozzle hole 19 having a constant diameter is formed in a predetermined length after being sequentially reduced in a conical shape, and a nozzle portion 21 is formed.
The swirling flow of the water is adjusted into a thin straight swirling flow in the nozzle hole 19, and becomes a thin linear swirling flow.

されながら旋回流とともに直進する。The base end of the mixing sleeve 13 is screwed to the outer periphery of the nozzle portion 21, and the first outer periphery and the distal end side of the nozzle portion 21 release the pressure of the swirling flow from the nozzle hole 19. The mixing chamber 22 is formed as a space surrounding the end of the nozzle section 21, and a gas supply nozzle 23 from the above-described ozone generator is provided on the peripheral wall behind the first mixing chamber 22 with the nozzle body 12 shaft. The connection opening is formed so as to intersect at an angle of 90 ° or less with respect to the core (swirl flow) direction. Ozone is supplied from the nozzle 23 at a low pressure of about 0.5 kg / cm 2 or less, is sucked into the swirling flow passing through the first mixing chamber 22, and travels straight along with the swirling flow while being mixed with water.

管29と接合されている。A straightening hole 24 having a diameter slightly larger than the nozzle hole 19 is formed in a predetermined length in front of the first mixing chamber 22 so as to form a taper whose diameter is sequentially reduced. It is arranged in a straight swirling flow and further enhances the mixing with ozone. Further, a second mixing chamber 26 having a hole having substantially the same diameter as that of the mixing chamber 22 is formed in front of the rectifying hole 24, and the outer periphery of the second mixing chamber 26 on the distal end side is connected to the bubble separator 27 side. The water supply pipe 29 is joined.

存率が高くなる。In the second mixing chamber 26, the ozone that has not been completely mixed until it exits the rectifying hole 24 is mixed while being engulfed in the swirling flow again. The swirling flow formed in the mixer 11 as described above flows linearly and in a streak flow into the second mixing chamber and the water supply pipe 29 and is concentrated at the center thereof.
The resistance to the inner peripheral surface of 29 etc. is small, the pressure loss decreases and the flow rate increases. In addition, since water forms a vortex in each cross section and converges at the center to form a swirling flow in a long range, the stirring and mixing of water and ozone are improved, and the dissolution rate of ozone is increased.

を用意することが可能である。The mixing sleeve 13 need not always be a sleeve, and its shape may be a block shape. When the nozzle body 12 and the mixing sleeve 13 are formed separately, various types of swirling chambers 17 on the nozzle body side having different dimensions and shapes are prepared to freely change and adjust the water flow rate and mixing ratio. Can be even more helical
By changing the nozzle 18 and the nozzle hole 19, it is possible to prepare a nozzle having a different mixing performance.

Is done. That is, the bubble separator 27 is composed of a pressure-resistant coupling 31 composed of, for example, a tank having an inner diameter of 100 mm and a height of about 350 mm, and an air vent 32 communicating with the inside of the upper end of the coupling 31 above the coupling 31. The water supply pipe 29 is connected and opened to the peripheral wall at a substantially intermediate height position, and a water supply pipe 33 for sending out ozone water is connected below the peripheral wall on the opposite side.

As a result, the supplied ozone water is
It rises to the upper part of the partition plate 34, flows over the partition plate 34, and flows downward to the lower water supply pipe 33.

とが出来る。<Effect of the Invention> As a result of the configuration of the mixer of the present invention as described above, when the gas is dissolved in the liquid, as in the case of dissolving ozone gas in water, the dissolution rate of the gas can be extremely increased. For example, in the case of dissolving ozone in water, a dissolution rate of 90% or more can be obtained with respect to the temperature, and it is safe and extremely high in sterilization, disinfection, deodorization, decolorization, etc. by each ozone cleaning as compared with the conventional one. High-concentration ozone water with high function can be obtained.
