More specifically, the blower inhales some ozone remaining and consumed when the polluted water such as wastewater and wastewater is purified by using an ozone contactor, and the inhaled ozone is By repeatedly supplying the inside of the ozone contactor through a blower, the ozone utilization rate can be greatly increased, and the ozone oxidation device having an ozone recycling function that can save energy by minimizing the power of ozone use.

그러나 이러한 종래 오존은 오존접촉기에서 한번 반응한 후 그대로 대기중으로 버려지기 때문에 경제성이 낮은 단점이 있었다. 또한 오존발생기에서 공급되는 기체상태의 오존과 액체 상태의 오염수는 오존접촉기를 통해 접촉이 일어나는데 기존의 경우 터보믹서, 라인믹서, 인젝터등을 이용하여 일정한 수조속에 기포를 주입하는 방식이기 때문에 많은 발생기 동력에 버금가는 동력의 소모가 있다.However, the conventional ozone has a disadvantage of low economical efficiency because it is discarded into the atmosphere after reacting once in the ozone contactor. In addition, the gaseous ozone supplied from the ozone generator and the contaminated water in the liquid state are contacted through the ozone contactor. In the conventional case, many generators are injected because bubbles are injected into a constant tank using a turbo mixer, a line mixer, and an injector. There is a consumption of power comparable to that of power.

그리고 한번 투입된 오존은 소독과 같이 5ppm 이하의 저농도를 필요로 할 경우 6m 정도의 깊이에서 60% 정도지만 고농도에서는 이용율이 급격히 떨어져 저 오염 물질이 있는 오폐수의 경우 30%이하로 감소하는 문제점이 있었다.And once the ozone is injected, such as disinfection requires a low concentration of less than 5ppm 60% at a depth of about 6m, but at a high concentration there is a problem that the utilization rate is sharply reduced to less than 30% in the case of waste water with low pollutants.

다만, 본 발명은 오존을 재이용할 수 있도록 한 것으로 이는 도1과 도2에서와 같이 본 발명에 따른 오존접촉기(200)는 내부에 일정한 간격을 가지고 수직 방향으로 분리 형성되면서 제1접촉공간(610)과 제2접촉공간(620)을 각각 분리 마련하는 분리벽(600)이 형성된다.However, the present invention allows the ozone to be reused, which is the first contact space 610 while the ozone contactor 200 according to the present invention is formed in a vertical direction at regular intervals therein as shown in FIGS. 1 and 2. ) And a separation wall 600 for separating and providing the second contact space 620, respectively.

제1접촉공간(610) 내부에는 상부로 이동하는 오존과 오염수의 접촉시간을 늘려주면서 1차반응시키는 제1접촉막(630)이 형성되며, 이러한 제1접촉막(630)은 이산화망간이 30중량% ~ 80중량% 함유된 세라믹볼로 이루어지고 제1접촉공간(610)상에 충진 형성될 때 50~100cm 두께로 채워진다.Inside the first contact space 610, a first contact film 630 for first reaction is formed while increasing the contact time of the ozone and contaminated water moving upward, and the first contact film 630 is made of manganese dioxide. It is made of a ceramic ball contained by weight to 80% by weight and is filled to a thickness of 50 ~ 100cm when the filling is formed on the first contact space 610.

이송관(650)의 일단은 제1접촉공간(610) 상단에 형성되고 타단은 제2접촉공간(620) 하단에 형성된 상태에서 제1접촉공간(610) 내부에서 반응 처리되고 남은 일부 오존이 압력조절밸브(660)를 통하여 제2접촉공간(620) 하단으로 안내되게 하는 역할을 수행한다.One end of the transfer pipe 650 is formed at the upper end of the first contact space 610 and the other end is formed at the lower end of the second contact space 620 to react with the remaining ozone in the first contact space 610. It serves to guide to the bottom of the second contact space 620 through the control valve 660.

제2접촉공간(620) 내부에는 제1접촉공간(610)에서 반응이 완료된 일부 오존과 오염수가 상부로 이동될 때 2차 반응시키는 제2접촉막(640)이 형성되며, 이러한 제2접촉막(640)은 스레인레스 금속박막으로 구성된다.Inside the second contact space 620, a second contact film 640 is formed to secondly react when some of the ozone and contaminated water that have completed the reaction in the first contact space 610 are moved upward. 640 is composed of a stainless steel thin film.

블로워(500)의 상단은 제2접촉공간(620) 상단과 연결 설치되고 하단은 통로(610)와 연결 설치된다. 이러한 블로워(500)는 오존접촉기(200) 내부에서 오존과 오염수가 혼합 용존되면서 기액분리가 이루어지면 소모되고 남은 일부 오존을 흡입하고, 흡입된 오존을 3회 이상 오존접촉기(200) 내부로 반복 공급하여 오존과 오염수가 재 접촉되게 하도록 구성된다. The upper end of the blower 500 is connected to the upper end of the second contact space 620 and the lower end is connected to the passage 610. The blower 500 inhales some remaining ozone when gas and liquid are separated while ozone and contaminated water are mixed and dissolved in the ozone contactor 200, and repeatedly supplies the inhaled ozone to the ozone contactor 200 more than three times. The ozone and contaminated water again.

이와 같이 구성된 본 발명의 오존발생기(400)는 오존을 발생시키고 발생된 오존은 통로(610)를 통하여 오존접촉기(200) 내부 하단으로 공급되고, 오,폐수와 같은 각종 오염수는 집수조(100) 내부에 집수된 후 이송펌프(110)에 의해 유입구(220)를 통하여 오존접촉기(200) 내부 하단으로 각각 유입된다.The ozone generator 400 of the present invention configured as described above generates ozone and the generated ozone is supplied to the lower end of the ozone contactor 200 through the passage 610, and various contaminated water such as wastewater and waste water is collected in the tank 100. After being collected therein, the feed pump 110 is introduced into the lower end of the ozone contactor 200 through the inlet 220.

오존접촉기(200) 하단으로 공급되는 오존은 기포를 발생하면서 상부로 상승하고, 오존이 상부로 상승할 때 제1접촉공간(610) 내부에 형성된 제1접촉막(630)을 거치는 과정에서 오존과 오염수와의 접촉시간이 늘어난다. 이때 오존이 오염수에 용존됨과 동시에 1차 반응하는 과정에서 오존은 소모되며 오,폐수와 같은 오염수는 정화처리 된다. The ozone supplied to the lower portion of the ozone contactor 200 rises to the upper side while generating bubbles, and when the ozone rises to the upper side, ozone and ozone in the process of passing through the first contact layer 630 formed inside the first contact space 610. Increased contact time with contaminated water. At this time, ozone is dissolved in contaminated water and ozone is consumed during the first reaction, and contaminated water such as waste and waste water is purified.

이후 제1접촉공간(610) 내부에서 반응 처리되고 남은 일부 오존은 이송관(650)과 압력조절밸브(660)를 통하여 제2접촉공간(620) 하단으로 안내되고, 제2차접촉공간(620) 하단으로 안내된 오존이 상부로 이동될 때 제2접촉막(640)을 거치면서 2차 반응 처리된다.Afterwards, the remaining ozone after the reaction treatment in the first contact space 610 is guided to the bottom of the second contact space 620 through the transfer pipe 650 and the pressure control valve 660, and the second contact space 620. When the ozone guided to the bottom is moved upward, the second reaction process is performed while passing through the second contact membrane 640.

한편, 오존접촉기(200) 내부에서 오존과 오염수가 혼합 용존되면 기액분리가 이루어지는데, 기액분리된 기체는 오존이 이에 해당하고 오존은 오,폐수를 정화 처리시 소모되며, 정화 처리된 오염수는 배출구(230), 처리수 이송펌프(300)를 통하여 방출된다. Meanwhile, when ozone and contaminated water are mixed and dissolved in the ozone contactor 200, gas-liquid separation is performed. The gas-liquid separated gas corresponds to ozone, and ozone is consumed when the wastewater is purified. It is discharged through the outlet 230, the treatment water transfer pump 300.

그리고, 제2접촉공간(620) 상부에서 소모되고 남은 일부 오존은 블로워(500)로 흡입되고 흡입된 오존은 통로(610)를 통하여 오존접촉기(200) 하단 내부로 3회 이상 반복적으로 공급되기 때문에 오존과 오염수는 반복 접촉되는 효과를 갖는다.Since some of the ozone consumed and remaining in the upper portion of the second contact space 620 is sucked into the blower 500 and the sucked ozone is repeatedly supplied to the lower portion of the ozone contactor 200 through the passage 610 at least three times. Ozone and contaminated water have the effect of repeated contact.
