Description

Description: TECHNICAL FIELD The present invention relates to a method and apparatus for mixing ozone with water, and more particularly, to an air passage and a water passage around an ultraviolet lamp.
Although it has a very simple structure by providing air and water horizontally in a heavy ring shape, it can mix a large amount of ozone with water and can directly irradiate the water with ultraviolet rays, which can be used for commercial fishponds, etc. The present invention relates to a suitable ozone mixing method and apparatus.

2. Description of the Related Art Conventionally, various devices have been put to practical use for mixing ozone into water such as fish ponds using an ultraviolet lamp. However, the conventional device is simply used in a water pipe when jetting water with a jet nozzle, for example. To partially increase the flow velocity along the flow of water, and to provide a T-tube at the tip of this jet nozzle to provide an ozone generation space above the T-tube in which air flows vertically downward. It was supposed to be provided. Therefore, if a slight increase in flow path resistance due to clogging or bending occurs in the water supply pipe at the tip of the jet nozzle,
Since the water level in the T-shaped tube rises, the suction of ozone-mixed air weakens, and there is a problem that a large amount of ozone cannot be mixed. Further, in such a structure, since the water is not directly irradiated with a large amount of ultraviolet rays, there is a drawback that the sterilizing effect of water and the cleaning effect of water by the ultraviolet rays themselves are not so large.

The present invention was made in order to eliminate the above-mentioned drawbacks of the prior art, and its object is to form a double structure of an air passage and a water passage around an ultraviolet lamp to form an annular shape. Provided, forming an ozone generation space on the side of the air passage,
By jetting the water in the water passage into the water supply pipe across the ozone generation space by the jet nozzle, ozone mixed air can be directly drawn into the water for mixing, and the amount of ozone mixed can be dramatically increased. The object of the present invention is to provide a method and an apparatus for mixing ozone that can be sufficiently practically used in fish ponds for commercial use, by greatly promoting biological purification treatment of water.

Another purpose is to form a cylindrical partition wall between the air passage and the water passage with a transparent quartz glass tube and a waterproof cylinder with an opaque synthetic resin so that the ultraviolet rays emitted from the ultraviolet lamp can be cylindrical. It is not absorbed by the partition wall, it is directly exposed to water, and by preventing it from leaking to the outside of the waterproof cylinder, powerful sterilization is done against water without any harm to the human body, The excellent chemical action of ultraviolet rays is to decompose organic matter such as fish excrement and leftovers of feed, prevent spoilage of water and foul odor, and improve transparency of water.

In summary, the method of the present invention comprises: irradiating the air in the air passage around the ultraviolet lamp with ultraviolet rays by the ultraviolet lamp to generate ozone, while allowing the air to flow horizontally around the ultraviolet lamp. Water is passed through a water passage formed in a ring shape outside the air passage and isolated from the outside air passage, and the water is jetted into the water supply pipe from the water passage across the ozone generation space communicating with the air passage. The water is mixed with ozone, and the ozone-mixed water is supplied into the water supply pipe.

The water 30 therein is sucked up as indicated by arrow A and is pumped into the water passage 6 from the water intake 4a.

The waterproof partition wall 22 is formed at the right end portion 4b of the waterproof cylinder 4 in the figure, and thus is screwed to the threaded portion 4c, and the seal members 31 are attached between the waterproof partition wall 4 and the tubular partition wall 21, respectively. Therefore, the waterproof treatment with the electric cylinder 3 is performed. Since the waterproof partition wall 23 is formed at the other end 4d of the waterproof cylinder 4, it is screwed to the threaded portion 4e, and the seal member 32 is attached between the waterproof partition wall 23 and the cylindrical partition wall 21 and between the waterproof cylinder 4 and the waterproof partition 4, respectively.

Operation The present invention is configured as described above, and its operation will be described below. When the plug 19 is connected to the power source and the power of the pump P is turned on, the pump P immediately starts rotating, and the ultraviolet lamp 2 lights up after a few minutes. Pump P
As a result, the water 30 in the water tank 29 is sucked into the hose 26 via the strainer 28 as shown by the arrow A, passes through the water intake joint pipe 25, and enters the water passage 6 in the waterproof cylinder 4 from the water intake 4a by the arrow A. The water flows in as shown, and the inside of the water passage 6 is maintained at a considerably high pressure by the water pressure. Therefore, the water in the water passage 6 is vigorously jetted from the jet nozzle 9 toward the inside of the water supply joint pipe 35, as shown by the arrow A, and the entire amount thereof enters the water supply joint pipe 35. In this case, the jet of water crosses the ozone generation space 8. On the other hand, when the ultraviolet lamp 2 is turned on, ultraviolet rays are radiated radially from the ultraviolet lamp, and the cylindrical partition wall 21 is formed of a transparent quartz glass tube. Therefore, the ultraviolet ray is not absorbed by the cylindrical partition wall 21. All the water in the water passage 6 is irradiated with the light. Therefore, the water is subjected to a strong sterilizing action, the bacteria in the water 30 pumped from the water tank 29 are killed, and the water becomes clean water and is jetted from the jet nozzle 9. In this case, the air in the air passage 5 generates ozone by the ultraviolet rays emitted from the ultraviolet lamp 2, and a large amount of ozone is generated in the ozone generation space 8 and accumulated therein. In this case, the sterilized water is constantly jetted from the jet nozzle 9 at a high speed in the water passage 6, and there is a high-speed jet of water here, so that the jet mixes the ozone in the ozone generation space 8. The air flows as shown by arrow B and is sucked into the water supply joint pipe 35 together with the water. Therefore, the outside air is sequentially sucked from the air inlet 3b of the electric cylinder 3 as shown by the arrow B and flows around the ultraviolet lamp 2 as shown by the arrow B as well, and ozone is generated one after another and gathers in the ozone generation space 8, From here, it is sent into the water supply pipe 34 together with water, and is mixed with the water 30 in the water tank 29 from the water supply pipe 39 via the filtering device 38. Since ozone returns to oxygen in water, it assists the generation and growth of aerobic bacteria and promotes biological purification treatment (biological filtration) of water. In addition, the increase in the amount of dissolved oxygen is
It will enhance the appetite of seafood and greatly promote its development.

Further, in the present invention, since the cylindrical partition wall 21 made of a quartz glass tube is provided around the ultraviolet lamp 2, the ultraviolet rays are not absorbed and are all radiated to the water 30 in the water passage 6, and all the water is sterilized. Will be received. Therefore, due to the excellent chemical action of ozone and ultraviolet rays, it is possible to decompose organic matter such as fish excrement and food leftovers and the like, thereby preventing water from spoiling and generating a bad odor, and increasing the transparency of water. Moreover, since the waterproof tube 4 is made of an opaque synthetic resin, the ultraviolet rays from the ultraviolet lamp 2 never leak to the outside, and thus do not harm the human body at all.

EFFECT Since the present invention is configured and operates as described above, there are two air passages and water passages around the ultraviolet lamp.
Since it has a heavy structure and is annularly formed, an ozone generation space is formed on the side of the air passage, and the water in the water passage is jetted across the ozone generation space into the water pipe by a jet nozzle. Since air can be directly entrained in water and mixed, the amount of ozone mixed can be dramatically increased compared to the conventional example, and the effect of significantly accelerating the biological purification treatment of water can be obtained. As a result, there is an effect that it can be sufficiently used mainly in commercial fish ponds and the like, and an ozone mixing method and apparatus can be provided.

Also, the cylindrical partition between the air passage and the water passage is made of a transparent quartz glass tube, and the waterproof cylinder is made of an opaque synthetic resin, so that the ultraviolet rays emitted from the ultraviolet lamp are absorbed by the cylindrical partition. Since it is directly exposed to water and does not leak to the outside of the waterproof cylinder, it is powerfully sterilized against water without any harm to the human body, and it has excellent chemical properties of ultraviolet rays. By the action, there is an effect that organic matter such as fish excrement and feed leftovers can be decomposed, water can be prevented from spoiling and a foul odor can be prevented, and the transparency of water can be increased.
