[0001]

[Industrial applications]

 The present invention relates to an ozone mixing device that injects ozone in order to sterilize and purify a water flow flowing in a water flow pipe and efficiently mixes and dissolves the ozone in the water flow.

[0002]

[Prior Art]

 Conventionally, in order to sterilize and purify water in various water tanks, a circulation type water flow pipe is formed to take out and return the water in the water tank, and an ozone supply device and a filtration device are provided in the middle of the water flow pipe. There are water treatment devices provided with an ultraviolet irradiation device. In this water treatment device, an ozone mixing device in which a plurality of resistance rods are arranged in an internal pipe and a main pipe in a state of intersecting with a water flow into which ozone has been injected is conventionally known (see JP-A-1-194990). ).

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, a diversion pipe is connected from the upstream side of the water flow pipe, an ozone injection part is provided in this diversion pipe, and the downstream side of this diversion pipe is made into an internal pipe, and the downstream side of the main pipe. It is further inserted into the center of the main pipe, and it is extended to the upstream side of the main pipe in parallel with the main pipe, and it is discharged from the tip against the main water flow, and both water flows are mixed by the collision phenomenon of the main water flow and the diversion flow. Furthermore, since a plurality of resistance rods are arranged in a state where they intersect with the water flow and the water flow is mixed by colliding with the resistance rod, a structure for mixing ozone with the water flow is provided, for example, by providing a diversion pipe. It is necessary to install a resistance rod, insert a diversion pipe in the main pipe, and install the tip so as to resist the main water flow, which makes the device itself complicated and expensive, and ozone Insert the diversion pipe to be injected into the main pipe to resist the main water flow. Since it is installed in the water supply system, the ozone-injected water stream must be provided with a pressurizing unit to discharge it against the main water stream. There was a problem that caused it. In view of this point, the present invention is an ozon that can reliably mix ozone with a water flow by closing the end of the water flow pipe and opening an appropriate number of holes in the water flow pipe to open the main pipe. It is intended to provide a mixing device.

[0004]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned problems, and in an ozone mixing apparatus, an ozone injection part is provided in an upstream water flow pipe, a lid is provided at an end of the upstream water flow pipe, and an upstream side is provided from the end. A suitable number of holes are provided around the upstream water flow pipe toward the appropriate length, and a main pipe is provided so as to cover the upstream water flow pipe in which the holes are formed, and the main pipe is provided at one end of the main pipe. The technical means of connecting the water flow pipe was adopted.

[0005]

[Action]

 According to the present invention, by adopting the above technical means, the ozone-injected water flow ejected from the numerous holes formed in the water flow pipe is discharged to the main pipe and discharged to the water flow pipe on the downstream side. At this time, since the end of the water flow pipe is blocked, the ozone-injected water flow is randomly ejected from many holes. When the ozone-injected water stream that has been ejected and is flowing into the main pipe, and the ozone-injected water stream that flows later is ejected from the multiple holes into the main pipe, it collides with the previously ejected water flow in the main pipe. To do. This is because the collision phenomenon occurs continuously simply by flowing the water flow that has been injected with ozone, and the ozone micronized by this collision is sufficiently mixed into the water flow.As a result, Since ozone gas is mixed and dissolved in a water stream in a mist state, it has a strong sterilizing and deodorizing effect.

[0006]

【Example】

 It is recognized that ozone treatment in water treatment technology is extremely effective for deodorization, removal of color, and inactivation of bacteria and viruses. An example of an optimum apparatus for mixing and dissolving ozone gas in water by this ozone treatment will be described in detail with reference to the accompanying drawings. A circulation type water flow pipe is formed that takes out water from a water tank (not shown) and returns it to the outside of the tank.In the middle of this water flow pipe, an ozone supply device, an ozone mixing device, a filtering device, an ultraviolet irradiation device, etc. are respectively provided. It is provided. Among these, as the ozone supply device, the filtering device, and the ultraviolet irradiation device, conventionally known existing devices are adopted, and thus detailed description thereof will be omitted. Therefore, the ozone mixing apparatus of the present invention will be described in detail with reference to FIG. 1. From the ozone injection section 2 at an appropriate location of the upstream water flow pipe 1, the water flow sent by a pump (not shown) or the like will be described. Ozone is injected, and the end 3 of the upstream water flow pipe 1 to which ozone-injected water is sent is closed with a lid 4 such as a screw-in type (this may be a fixed closed lid or a removable lid. However, a plurality of holes 5 are regularly or irregularly formed around the water flow pipe in an appropriate length range from the closed end portion 3 toward the upstream side. From the upstream side to the downstream side, the holes are arranged such that the holes are arranged in order from the largest to the smallest, the smaller holes are arranged alternately, or the smaller holes are arranged to the larger hole. Further, the same holes 5 are provided (this is because even in the same hole, due to the water pressure, the force ejected by each hole and the timing vary). Then, a main pipe 6 having a diameter larger than that of the water flow pipe is provided so as to cover the portion of the hole 5 bored in the upstream water flow pipe 1, and the end portion 7 of the main pipe on the upstream side is fixed to the upstream water flow pipe 1. The end portion 7 of the downstream main pipe is fixedly connected to the downstream water flow pipe 8. The main pipe 6 may be attached by welding or the like, or may be detachable by using a flange or the like. Further, both ends of the main pipe 6 are inclined or conical so as to remove the corners 12 as shown in the figure, and the inclined end portion 9 of the main pipe 6 is provided so as to smooth the flow except for a portion that collects even a little. May be provided. When adopting the inclined end portion 9 of this main pipe, the corner portion 12 is naturally removed. Ozone is supplied from the ozone generator 10 to the water flow pipe from the hose 11 via the compressor (not shown) and the ozone injection part 2. When a larger ozone supply amount is required, a spare supply port may be provided so as to connect to another ozone generator. Then, this ozone-injected water is sent through the water flow pipe, but since the end portion 3 of the upstream water flow pipe 1 is closed, each of the holes formed in a certain range of the upstream water flow pipe 1 The ozone-injected water is ejected from the hole 5 toward the inside of the main pipe 6, and at the time of ejection, the ozone-injected water is mixed with the ozone-injected water that has been ejected into the main pipe 6 and is flowing. , Dissolve. Moreover, the ozone-injected water ejected from each hole 5 repeatedly collides with a time lag and is sent toward the downstream side, and the ozone is quickly and evenly mixed and dissolved, so the water is deodorized. It is sterilized and circulated through the downstream water flow pipe 8. It should be noted that the ozone gas in the water flow pipe is discharged after it is converted to oxygen gas by irradiating it with ultraviolet rays, etc., so that the surrounding atmosphere is not affected and safer and cleaner treatment can be performed.
