The mixing chamber 1 is a place where the introduced seawater is mixed with ozone air by a pump, and there is an inlet 1a through which the seawater for purified water flows in. The inflowed seawater is pumped through a suction pipe 8a. The mixture is introduced into the air, mixed with ozone air, purified, and reintroduced through the discharge pipe 8b.

분리실(2)은 오존공기와 혼합되어 정수된 해수는 혼합실(1)에서 상승공(2a)을 통해 이 곳으로 유입되며, 이의 해수는 다량의 기포를 수반하게 된다. 따라서 이 곳에서는 해수속에 있는 기포를 분리하기 위한 곳으로, 해수는 하강공(2b)을 통해 저장실(3)에 모이게 되고, 기포는 기포유도관(4a)을 따라 기포수집실(5)에 모이게 된다.The separation chamber 2 is mixed with ozone air and the purified seawater is introduced into the place through the rising hole 2a in the mixing chamber 1, and the seawater is accompanied by a large amount of bubbles. Therefore, in this place, to separate the bubbles in the seawater, the seawater is collected in the storage chamber (3) through the downhole (2b), bubbles are collected in the bubble collection chamber (5) along the bubble induction pipe (4a) do.

배출실(4)은 정수되고 기포가 분리된 해수가 모이는 곳이며, 배출구(1b)를 통해 원하는 곳에 이 해수를 공급하게 된다.The discharge chamber 4 is a place where the seawater where the purified water and the bubbles are separated is collected, and the seawater is supplied to the desired place through the discharge port 1b.

기포수집실(5)은 분리실(2)에서 분리된 기포가 모이는 곳이며, 기포배출구(5a)를 통해 기포속의 공기가 빠져나게 된다. The bubble collection chamber 5 is a place where the bubbles separated in the separation chamber 2 are collected, and the air in the bubbles escapes through the bubble discharge ports 5a.

모터실(6)에는 펌프(8)와 이를 구동시키는 모터(6a)가 장치된 곳이며, 펌프(8)는 흡입관(8a)과 배출관(8b)을 통해 혼합실(1)과 연결된다. 흡입관(8a)을 통해 혼합실(1)의 해수가 펌프(8)로 유입되고, 또한 오존실(7)에 있는 오존발생기(7a)로부터 생성된 오존공기가 오존공기배출관(7d)을 통해 이 흡입관(8a)과 연결됨으로서 정수를 위한 해수와 정수역할을 하는 오존공기가 동시에 펌프(8)내로 혼합유입되는 것이며, 유입된 해수는 일반적으로 펌프(8)에 사용하는 다수개의 안내날개(9a)가 부착된 임펠러(9)와 달리, 이의 안내날개(9a)에 다수개의 관통홀(9b)을 형성한 것으로 펌프(8)내에서 해수의 파쇄효과를 높힌 것이다.The motor chamber 6 is a place where the pump 8 and the motor 6a for driving the pump chamber 6 are installed, and the pump 8 is connected to the mixing chamber 1 through the suction pipe 8a and the discharge pipe 8b. The seawater of the mixing chamber 1 flows into the pump 8 through the suction pipe 8a, and the ozone air generated from the ozone generator 7a in the ozone chamber 7 passes through the ozone air discharge pipe 7d. By being connected to the suction pipe 8a, seawater for purified water and ozone air acting as a purified water are simultaneously introduced into the pump 8, and the introduced seawater is a plurality of guide vanes 9a generally used for the pump 8. Unlike the impeller 9 is attached to the plurality of through-holes (9b) formed in the guide wing (9a) is to increase the crushing effect of seawater in the pump (8).

오존실(7)에는 오존공기를 발생하여 펌프(8)에 공급시키는 오존발생기(7a)가 설치되어 있으며, 이는 공기유입구(7c)로부터 공기가 유입되고, 공기필터부(7b)를 거쳐 공기유입관(7e)을 통해 오존발생기에 공기가 유입된다. 이는 다시 오존발생 기(7a)에서 오존공기를 생성시켜 오존배출관(7d)을 통해 펌프(8)의 흡입관(8a)에 연결되어 펌프(8)내로 공급하게 된다.The ozone chamber 7 is provided with an ozone generator 7a for generating ozone air and supplying it to the pump 8. The air flows in from the air inlet 7c and flows through the air filter unit 7b. Air flows into the ozone generator through the pipe 7e. This in turn generates ozone air in the ozone generator 7a and is connected to the suction pipe 8a of the pump 8 through the ozone discharge pipe 7d to be supplied into the pump 8.

이상과 구성된 본 발명의 실시예를 설명하면 다음과 같다.An embodiment of the present invention configured as described above is as follows.

정수를 위한 해수는 외부의 펌프(미도시)에 의해 유입구(1a)를 통해 혼합실(1)로 공급되면, 모터(6a)를 가동시켜 펌프(8)를 구동시킨다. 이에 펌프(8)내의 임펠러(9)가 고속 회전함에 따라 생기는 흡입력에 의해 혼합실(1)의 해수가 흡입관(8a)을 통해 펌프(8)내로 유입된다. 이 때 공기유입구(7c)와 공기필터부(7b)를 거쳐 정화된 공기는 오존발생기(7a)내로 유입되어 미량(0.05~0.10ppm)의 오존이 함유된 오존공기가 되어 흡입관(8a)에 연결된 오존공기배출관(7d)을 통해 배출되어 해수와 함께 펌프(8)내로 유입된다. 이와 같이 유입된 해수와 오존공기는 펌프(8)내에 고속 회전하는 임펠러(9)에 의해 해수를 파쇄시키게 되어, 해수는 미세기포화되어 오존공기가 투입 용존된다. 혼합실(1)내의 해수는 상기와 같은 과정을 반복하게 된다. 상기의 과정을 거친 해수속에는 다량의 기포가 섞여지게 되어, 이를 분리해야 한다. 따라서 이를 위해서 정수된 해수는 상승공(2a)을 통해 분리실(2)로 유입되며, 이 곳에서 해수속의 기포는 기포유도관(4a)을 통해 기포수집실(5)로 모이게 되며, 기포가 걸러진 해수는 하강공(2b)을 통해 저장실(3)에 모이게 된다. 이 해수는 연결관(2c)을 거쳐 배출실(4)로 유도되어, 배출구(1b)를 통해 원하는 곳에 정수된 해수가 공급되는 것이다.When the seawater for water purification is supplied to the mixing chamber 1 through the inlet port 1a by an external pump (not shown), the motor 6a is operated to drive the pump 8. Accordingly, the seawater of the mixing chamber 1 flows into the pump 8 through the suction pipe 8a by the suction force generated by the high speed rotation of the impeller 9 in the pump 8. At this time, the purified air through the air inlet (7c) and the air filter unit (7b) is introduced into the ozone generator (7a) is a ozone air containing a small amount (0.05 ~ 0.10ppm) of ozone connected to the suction pipe (8a) It is discharged through the ozone air discharge pipe 7d and flows into the pump 8 together with the sea water. The seawater and ozone air introduced in this way are crushed by the impeller 9 which rotates at high speed in the pump 8, and the seawater is micro-bubble and ozone air is added and dissolved. The seawater in the mixing chamber 1 repeats the above process. The seawater that passed through the above process is mixed with a large amount of bubbles, it must be separated. Therefore, the seawater purified for this purpose is introduced into the separation chamber (2) through the ascending hole (2a), where bubbles in the sea water are collected into the bubble collection chamber (5) through the bubble guide pipe (4a), bubbles The filtered seawater is collected in the storage compartment 3 through the downhole 2b. This seawater is led to the discharge chamber 4 via the connecting pipe 2c, and the purified seawater is supplied to the desired place through the discharge port 1b.

이상의 설명은 주로 해수를 정수하는데 관하여 설명하였으나, 본 발명은 해수의 정수에 한정하지 않고 담수를 정수 및 살균하는데에도 적용되는 것이다.Although the above description has been mainly described regarding the purification of seawater, the present invention is not limited to the purification of seawater, but also applies to the purification and sterilization of fresh water.

이상과 같이 본 발명은 활어수조 내에 활어가 생활하기에 최적한 농도의 오존수(0.03~0.05ppm)을 생산함에 있어서, 공기필터부(7b)를 거쳐 정화된 공기는 오존발생기(7a)내로 유입되어 미량(0.05~0.10ppm)의 오존이 함유된 오존공기가 되어 흡입관(8a)에 연결된 오존공기배출관(7d)을 통해 배출되어 해수와 함께 펌프(8)내로 유입되도록 하고, 펌프(8)내에 고속 회전하는 임펠러(9)에 의해 해수는 파쇄되어 미세기포화 되며, 이 해수에 오존공기가 투입 용존되는 것으로, 좁은 공간의 펌프(8)내에서 오존공기에 의해 정수 및 살균이 이루어지기 때문에 보다 간단한 구조로서 소음발생을 억제하면서 보다 높은 효율의 정수 및 살균이 이루어짐으로써 용존효율이 높은 경제적인 오존해수 및 담수를 얻을 수 있어 산업적으로 매우 유용한 것이다. As described above, the present invention produces ozone water (0.03 to 0.05 ppm) having an optimal concentration for living fish in a live fish tank, and the air purified through the air filter unit 7b is introduced into the ozone generator 7a. Ozone air containing a small amount (0.05 to 0.10 ppm) of ozone is discharged through the ozone air discharge pipe (7d) connected to the suction pipe (8a) to be introduced into the pump (8) with sea water, and the high speed in the pump (8) The seawater is crushed by the rotating impeller (9) to form micro-bubbles, and ozone air is introduced and dissolved in the seawater, which is simpler because water purification and sterilization are performed by ozone air in the pump (8) in a narrow space. As it is possible to obtain high-efficiency water purification and sterilization while suppressing noise, economical ozone seawater and fresh water with high dissolved efficiency can be obtained, which is very useful industrially.
