Description

  The present invention relates to an apparatus for dissolving a gas in a liquid excellent in the performance of dissolving the gas in the liquid in gas-liquid mixing for efficiently mixing the gas and the liquid, particularly ozone gas and water, and particularly to an ozone water generator. .

Ozone water is used not only for sterilization of medical equipment but also for a wide range of fields such as sterilization of food and preservation of freshness. Not only for large food factories and livestock facilities, but also for relatively small kitchen facilities, bathrooms, examination rooms, and laundry facilities. Generally, in an ozone water generator, ozone gas is pressurized and injected into raw water, or gas is self-injected and injected with an aspirator or the like to mix and dissolve ozone gas.
Many relatively small ozone water generators are not equipped with a high-pressure pump, a dissolution tank, and the like, and there are many types in which a gas and a liquid are simply mixed by an aspirator using tap water pressure. For example, Japanese Unexamined Patent Application Publication No. 2004-223441 (Patent Document 1) discloses a simple mixer connected to the downstream side of an aspirator that mixes tap water and ozone gas to promote dissolution and mixing.
The downstream side pipe is filled with a lot of oxidation-resistant beads to disperse, invert and convert bubbles (ozone gas), expand the contact area of ozone gas and tap water, increase the contact time, and ozone gas The amount of dissolution is improved. In other words, in addition to gas-liquid mixing / dissolution by an aspirator, further promoting it is an important issue in downsizing and simplifying the structure of the ozone water generator.

In order to secure the dissolving action of the ozone water in the bellows tube, it is desirable to provide the bellows tube in a circular shape as shown in FIG.
Next, the Example of the gas-liquid mixing unit used for the ozone water generator of this invention is described.

As shown in FIG. 2, the gas-liquid mixing unit of Example 1 is supplied with raw water 6 that is a liquid from a raw water supply pipe 3 attached to the upper part, and is attached to the side (from the left in FIG. 1). The gas ozone pipe 7 is supplied from the gas lead pipe 4 and the end of the raw water supply pipe 3 is screwed to the gas-liquid mixing unit 1 with the unit connecting pipe 2 having the unit outlet 1b penetrating through the center. It is configured. Furthermore, a stirring unit for stirring the running water is attached to the water discharge path portion 1 a formed on the outlet side of the unit connection pipe 2. The tip of the unit connection pipe 2 is connected to the bellows pipe opening 20 a of the bellows pipe 20 by the joint ring 5.
In the gas-liquid mixing unit 1 of the first embodiment configured as described above, the raw water 6 introduced from the raw water supply port 3a is supplied with ozone gas 7 supplied from the gas reed pipe 4 when jetted from the raw water jet port 3b. It flows into the unit outlet 1b while sucking. At this time, since the inside of the gas-liquid mixing unit 1 is depressurized by the flow rate of the raw water 6, the sucked ozone gas 7 passes through the water discharge path portion 1 a of the gas-liquid mixing unit 1 while being mixed and dissolved in the raw water 6. Then, it passes through the gap of the stirring unit (conical coil spring in this embodiment) 10 provided on the outlet side of the water discharge path portion 1a and flows into the bellows tube 20 from the bellows tube opening 20a.

  As shown in FIG. 2, the stirring unit 10 according to the first embodiment has a conical coil spring fitted in the throttle opening of the unit connecting pipe 2 so as to be installed in the unit water discharge path 1a. The internal position of the conical coil spring 10 may be anywhere as long as it is within the unit water discharge path portion 1a, and may be directly provided at the bellows tube opening.

FIG. 3 shows that in Example 1, a conical coil spring 10 is provided on the outlet side of the unit water discharge path portion 1 a formed on the outlet side of the unit connection pipe 2, and a part of its tip extends to the inside of the bellows pipe 20.

As shown in FIG. 3, the tip of the unit connection pipe 2 is connected to the bellows pipe opening 20 a of the bellows pipe 20 by the joint ring 5 with the packing 5 a sandwiched between the connection gaps.
In addition, the bellows tube 20 used in Example 1 is provided with a spiral unevenness or ring-shaped unevenness that circulates around the tube body, and is also a foldable tube called a serpentine hose, a flexible tube (flexible tube), a flex tube, or the like. Therefore, it is a well-known member that is also frequently used as an outdoor circulation pipe for a cooling / heating unit, a hot water supply connecting pipe, an electric wire protection pipe, and the like.

FIG. 4 is a partially broken cross-sectional view showing Example 2 of the gas-liquid mixing unit used in the ozone water generator of the present invention. The gas-liquid mixing unit 1 of the second embodiment is the same as the gas-liquid mixing unit of the first embodiment except that a gas lead pipe 4 for sucking ozone gas is joined to the middle of the orifice. The ozone gas 7 can be applied with an external pressure in addition to the suction action by the orifice.
Also in the second embodiment, the conical coil spring 10 is fitted and fixed to the water discharge path portion 1a of the gas-liquid mixing unit as in the first embodiment. The tip of the conical coil spring 1 is inserted from the bellows tube opening 20a toward the inside of the bellows tube 20. The raw water 6 mixed with the orifice and the ozone gas enter the spiral gap of the conical coil spring 10 provided in the water discharge path portion 1a and collide with the inner wall of the tube radially in the vicinity of the bellows tube opening 20a while generating a swirling flow. Thereafter, while the raw water mixed with the ozone gas passes through the bellows tube 20 while repeating turbulent flow generation and swirl flow generation due to the spiral irregularities of the inner wall of the tube, dissolution of the ozone gas into the raw water is promoted.

FIG. 5 is a partially broken sectional view showing Example 3 of the gas-liquid mixing unit used in the ozone water generator of the present invention. In the gas-liquid mixing unit 1 of the third embodiment, the raw water supply pipe 3 in which the gas lead pipe 4 is taken is introduced from the vertical direction with respect to the pipe peripheral surface of the water discharge path portion 1a.

Different from mixing unit.
In the gas-liquid mixing unit 1 of the third embodiment, the ozone gas 7 is guided from the gas lead pipe 4 into the gas-liquid mixing unit 1. When the suction pressure of the ozone gas is insufficient, the ozone gas 7 can be pressurized and injected by an external pressurizing means. The ozone water that has sucked ozone gas at the outlet 1b of the gas-liquid mixing unit 1 collides perpendicularly with the conical coil spring 10 from the outer peripheral direction in the water discharge path portion 1a of the gas-liquid mixing unit 1 to generate a swirling flow. The intense whirling flow passes through the connection portion and passes into the bellows tube 20 as it is. The gas dissolution is further promoted inside the bellows tube 20 as described in the second embodiment.

  FIG. 6 is a partially broken cross-sectional view showing Example 4 of the gas-liquid mixing unit used in the ozone water generator of the present invention. The gas-liquid mixing unit 1 according to the fourth embodiment is different in that, instead of the conical coil spring 20 according to the third embodiment, a rod body 11 having a spiral groove is fixed upright on the inner wall of the fixed lid 1c. This is the same as the gas-liquid mixing unit of the third embodiment. In the gas-liquid mixing unit 1 of the fourth embodiment, ozone water from the unit outlet 1b collides perpendicularly with the outer peripheral surface of the rod body 11 having a spiral groove in the unit outlet passage portion 1a to generate a swirling flow. The ozone water which has become a vigorous whirling flow passes through the bellows tube 20 through the connecting portion as it is. As described above, the dissolution of ozone gas is further promoted inside the bellows tube 20. The state in which the tip of the rod 11 having the spiral groove is inserted deeply into the bellows tube 20 can particularly enhance the effect of promoting ozone gas dissolution.

The ozone water generator according to the present invention generates ozone water with a high ozone concentration by mixing and dissolving ozone gas in a short time by providing a passage that generates whirling and turbulent flow in running water such as tap water. The ozone water generator can be miniaturized and the structure can be simplified, and the industrial utility value is extremely high.
