Description

[Detailed description of the invention] (Purpose of the invention and industrial application field) The invention relates to a reaction water supply device for gases such as ozone and oxygen, which generates water for washing and sterilizing processed foods. The water is used for washing meat, processed foods, etc. and as sterilizing water.

(Prior art of the present invention and problems to be solved) Currently, large amounts of water are used to wash meat and processed foods, and gases such as ozone and oxygen are mixed into this water for washing and sterilization. It is used as water for personal use.

Conventionally, the above-mentioned supply of reaction water containing gases such as ozone and oxygen has been carried out by releasing gases such as ozone into the passing water in the form of bubbles using an aeration pipe to generate reaction water. The reaction water of this type of equipment has a poor production rate due to the contamination of gases such as ozone, has difficulties in cleaning and sterilization, and lacks the ability to meet the demand for sufficient reaction water required for food processing. Therefore, a reaction water supply device that can supply a large amount of water has been desired.

The present invention has devised a supply device that can technically improve the above-mentioned difficulties and generate a large amount of effective gaseous reaction water such as ozone.

Hereinafter, specific embodiments of the present invention will be illustrated and explained.
The present invention is a vertical column-shaped reaction water supply apparatus made of a strong corrosion-resistant metal material. Figures 1 to 3 show the implementation configuration of a general-purpose ozone reaction water supply apparatus. 6 to 6 show an embodiment of a large amount ozone reaction water supply apparatus according to claim 2.

First of all, the embodiment of claim 1 shown in FIGS. 1 to 3 has a driving section a at the top, an ozone gas press-in section b in the middle, and a reaction chamber c at the bottom. (not shown) is a cylindrical supply device that is assembled in sequence through mounting plates on the top (not shown).

To explain in detail below, the uppermost driving section a has a cylindrical container body 10 equipped with a motor 11 as a driving source, and the container body is mounted on a receiving plate 12. A press-fitting part b for ozone air is provided at the lower part of the drive part a, and a support rod 14 is used to support between the receiving plate 12 and the lower receiving plate 13 of the driving part, and a chain coupling ring 15 is connected to the drive shaft provided below the driving part. The rotary shaft 16 is connected in an adjustable manner. An injection hole 17 for injecting ozone gas is vertically provided in the rotating shaft 16 and communicates with an ozone injection hole 19 of a bearing 18 mounted on the rotating shaft. Reference numeral 20 denotes an injection pipe attached to the ozone injection hole, which projects from the bearing 18 to the outside of the container. 21 is an injection nozzle. 23 is an annular groove provided in the bearing, and the injection pipe 20
The injected ozone gas is continuously injected into the injection hole of the rotating shaft via the annular groove. The bearing includes a bearing 22 and a washer 24 with a packing. C is a reaction chamber provided at the lower part of the injection part, and a stirring shaft cylinder 25 is connected to the lower part of the rotating shaft inside the reaction chamber. Reference numeral 26 indicates an ozone gas ejection hole drilled in a hanging stirring shaft cylinder, and reference numeral 27 indicates a stirring blade. As shown in Figure 3, three stirring blades are installed on the stirring shaft at 120° intervals, and water is taken in and stirred from the intake port 28 at the bottom of the reaction chamber, and the ozone gas spouted from the jet hole is stirred therein. The mixture is mixed to produce reaction water containing ozone, which is supplied from the supply port 29. As shown in FIG. 3, the stirring blades are mounted at regular intervals so as to generate a negative pressure on the opposite side of the rotation direction of the blades in order to reduce the ozone blowout action. In the example, the number of plates is 3, but the number may be increased or decreased to about 2 to 5 depending on the size of the reaction chamber and the diameter of the stirring cylinder. The flow rate of water to the reaction chamber is adjusted by installing a flow rate control valve 30 at the intake port.

Figures 4 to 6 show a reaction water supply device for a large amount of gas such as ozone as set forth in claim 2. The first difference from the small-sized reaction water supply device shown in paragraph 1 is that The mechanism must be such that reaction water is supplied uniformly and at an appropriate concentration to the water. Secondly, the reaction time should be lengthened in order to achieve uniform stirring and mixing. Thirdly, even though it is large, it should be vertical, which occupies less space.
This is a mechanical device that addresses these three issues and solves them.

The example is a cylindrical vessel 31 with a height of approximately 200 cm.
The intake part 32 was provided at the base, and the reaction chamber 36 was separated from the intake part at the upper part, and the reaction effect was reduced. That is, the ozone extraction pipe 33 was attached to the lower part of the container body, and the water jetting pipe 34 was attached to eject the water to the upper part of the container body. The ozone outlet pipe 33 is provided with a micron-sized ozone outlet hole 35 to reduce the effect of mixing with water, and the ozone outlet tube 33 is provided with an ozone outlet fine hole 35 in the micron unit to discharge water and ozone gas to the upper reaction chamber 36 at the same time. The reaction chambers are vertically installed in order to prolong the reaction time between a large amount of water and ozone gas and obtain uniform reaction water. In the reaction chamber, a plurality of stirring blades 38, 38 are attached to a stirring shaft 37 hanging from an upper driving source, and two stirring blades are used to stir water containing ozone gas to produce a uniform and appropriate concentration. Use as reaction water. As shown in FIGS. 5 and 6, the stirring blade 38 is installed horizontally to the stirring shaft vertically installed in the room, and at an installation angle of 30°.
The ozone-containing water rising from the intake part in the range of ~50° is held down to prolong the residence time of the passing water and ozone gas, and rotational agitation ensures that ozone bubbles are evenly mixed in, and It is produced as reaction water with an appropriate concentration. 39 is a bearing, 40 is a reaction water supply section, and 41 is a supply port. 42 is a drive motor;
43 is a chain spring, 44 is a bearing,
45 is a bearing, 46 is a support shaft, 47 is a mounting plate for each mechanism, and 48 is a support leg for the body device.

(Effects of the present invention) The present invention is an apparatus for supplying reaction water using gases such as ozone having the structural functions described above, and the reaction water supply apparatus shown in FIGS. This is a supply device with a simple structure that takes water and ozone directly into the reaction chamber installed at the base of the device, reacts the ozone gas ejected from the stirring cylinder with water, and supplies it as reaction water from the supply port. The test results showed that the following features and advantages were obtained compared to the reaction water supply structure using a diffuser tube.

First of all, the ozone admixture rate of the reaction water produced was conventionally 10%, but with this invention, it has been increased to 30%, which significantly improves the functionality of the device and provides reaction water with high cleaning and sterilizing effects. It became. Regarding the reaction water containing oxygen gas, a reaction effect of about 60% can be obtained. Structurally, the stirring blade has the advantage of sucking in ozone gas and reducing its ejecting action due to its rotating action that generates negative pressure around the shaft, supplying highly concentrated reaction water in a short period of time. Furthermore, the mechanism is simple and it is practical as a compact device with few failures.

Next, a large-sized device capable of supplying a large amount of ozone reaction water as shown in claim 2 takes in pressurized water and ozone air and blows it out into the reaction chamber at the top of the device, and has stirring blades installed in two stages, upper and lower, and strikes each downwardly. Since the water is stirred and rotated so that even a large amount of water is used, it is not temporary, and the mixing time with ozone gas is extended, so reaction water with a concentration suitable for sterilization and cleaning can be supplied.
According to tests, about 10 tons of reaction water can be obtained per hour, so it can be used as a large-scale supply device for mass production in factories. Further, by using several units of this apparatus connected in series, a larger amount of reaction water can be obtained.

As described above, the present invention is practical as an effective supply device for a gas such as ozone and has good reaction accuracy.
