Description

기액 계면결합장치 {Fluid Film Coupling System}Gas-liquid interfacial bonding device {Fluid Film Coupling System}

본 발명은 액체에 특수기체를 결합시켜 액체의 특성을 살리는 장치에 관한 것으로서, 물의 경우, 산소가 부족한 물에 Do를 높혀 생물학적 호흡과 화학적 산화 촉진으로 수질개선을 하는 수처리장치에 관한 것이다.The present invention relates to a device that combines a special gas to the liquid to improve the properties of the liquid, in the case of water, a water treatment device for improving water quality by promoting Doo in the oxygen-deficient water to promote biological respiration and chemical oxidation.

일반적으로 물에 산소를 녹이는 장치 (Do)로서 (a) 물속에 공기를 분산 (수중산기 ; 디퓨져) 하는 방법과 (b)공기속에 물을 분산 (표면포기 ; 분수) 하는 방법이 있다. (a) (b)의 목적은 물과 공기의 접촉면적과 접촉시간을 극대화함에 있다. 접촉시간은 (a)의 경우 기포의 부력, (b)의 경우 수포의 중력을 극소화 해야 하고, 접촉면적은 기포, 수포의 크기에 역비례 하므로 크기를 극소화 해야 한다.Generally, as a device (Do) for dissolving oxygen in water, there is a method of (a) dispersing air in water (diffuser; diffuser) and (b) dispersing water in air (surface aeration; fountain). (a) The purpose of (b) is to maximize the contact area and the contact time between water and air. The contact time should minimize the buoyancy of bubbles in (a) and the gravity of blisters in (b), and the contact area should be minimized because it is inversely proportional to the size of bubbles and blisters.

미세 기포발생의 종래 기술은 물리적 산기기나 분사방식이었으나 미세기포의 극소화에 한계가 있으며, 산기기의 이물질 막힘을 피할 수 없었다.The prior art of microbubble generation has been a physical diffuser or injection method, but there is a limit to minimizing the microbubbles, and clogging of foreign matter in the diffuser is inevitable.

본 발명은 이러한 종래 기술의 문제점을 해결하기 위한 것으로서, 액체에 기체의 성분을 최단시간에 효율적으로 다량 결합시키는데 그 목적이 있다.The present invention has been made to solve the problems of the prior art, and an object thereof is to efficiently and efficiently bind a large amount of gas components to a liquid.

이와 같은 상기의 목적을 달성하기 위해 발명된 계면결합장치는 자체 가압펌프의 흡입 양정력(0.8 KPa)을 이용하여 기체 소모분을 자동 보충하는 기액 혼합장치를 두고, 가압펌프 후단에 기액 접촉시간과 기액 접촉면적을 증대 시키기 위한 분리장치 (기체모음판) 를 수평적층 배열하여, 액체가 그 사이를 회유하며 계면결합압력 (2 . 7 5 KPa)을 받아 계면결합하는 구성의 특징이 있다.In order to achieve the above object, the interface coupling device invented has a gas-liquid mixing device that automatically replenishes gas consumption by using suction lift force (0.8 KPa) of its own pressurized pump. A horizontal stacking arrangement of separators ( gas collection plates ) for increasing the gas-liquid contact area is provided, and the liquid is interfacially bonded under the interfacial bonding pressure (2.5 KPa).

또한, 본 발명에 따른 계면결합장치를 설치함에 있어서 액체 유입구에 5 0 μ정도의 여과장치를 설치하고, 기체 유입구에 특수기체를 정량 투입 할 수 있는 인젝터가 설치됨이 바람직하다.In addition, in installing the interfacial coupling device according to the present invention, it is preferable to install a filtration device of about 50 μm at the liquid inlet, and an injector capable of quantitatively injecting special gas into the gas inlet.

이하 첨부된 도면에 의거 본 발명을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

〈도3〉에서 나타난 바와 같이, 본 장치의 구성은 기액 혼합단계와 기액분리, 계면결합단계로 크게 나눌 수 있다.As shown in FIG. 3, the configuration of the apparatus can be roughly divided into a gas-liquid mixing step, a gas-liquid separation, and an interfacial bonding step .

기액 혼합단계는 〈도4〉에서 나타난 바와 같이. 압력탱크 ( 2 ) 내의 수위를 검지하는 수위센서 ( 3 ) 와 검지신호에 따라 작동하는 수위조절기, Time Relay, 전기회로 등이 내장된 제어함 ( 4 ) 과 이에따라 제어되는 전자변 ( 5 ) 과 전자변 ( 5 ) 의 상태에 반응하는 날름변 ( 6 ) 으로 구성한다. The gas-liquid mixing step is shown in <Fig. 4>. A pressure tank (2) water level regulator that operates in accordance with the water level sensor 3, and a detection signal for detecting the water level in the, Time Relay, that this built-in control electric circuit 4 and yiettara control solenoid valve 5 and the solenoid valve is ( 5) consists of cutting edges (6) which respond to the state of.

〈도4〉에서 나타난 바와 같이 작동중 미세기포 생산으로 기체가 소모되어 압력탱크 ( 2 ) 내의 수위가 상승 (수위 ; A)하면 수위센서 ( 3 ) 의 검침봉 (가) (나) (다) 가 물에 의해 전기적 단락되어 검침봉 (나) (다) 가 개방될 때까지 수위조절기가 작동한다.As shown in Figure 4, when gas is consumed by the production of microbubbles during operation and the water level in the pressure tank (2) rises (water level; A), the reading rod of the water level sensor (3) (a) (b) (c) The water level regulator is operated until it is electrically shorted by water and the meter reading rod (b) is opened.

수위조절기가 작동하면 Time Relay가 〈도4〉에 표시된 것처럼 2초 닫고 8초 열림을 반복한다. 이 결과 전자변 (5)이 닫힌 2초동안 압력펌프( 1 ) 의 흡입 양정력이 날름변 ( 6 ) 을 개방시켜 기체가 흡입된다. 상기 동작은 제어함 ( 4 ) 내의 수위조절기가 기체 충진으로 수위하강 (수위 ; B) 될 때까지 작동한다. 이런 간헐작동은 압력펌프 ( 1 ) 에 유입되는 기체의 양을 조절하여 압력펌프 ( 1 ) 의 공회전을 막기 위함이다. When the level controller is activated, the Time Relay closes for 2 seconds and repeats opening for 8 seconds as shown in Figure 4. As a result, the suction lift force of the pressure pump 1 opens the cutting edge 6 for 2 seconds when the electromagnetic valve 5 is closed, and gas is sucked in. The operation is operated until the level controller in the control box (4) drops to level (B) with gas filling. This intermittent operation is to prevent the idling of the pressure pump (1) by adjusting the amount of gas flowing into the pressure pump (1).

기액분리 및 계면결합단계에 있어서, In the gas-liquid separation and interfacial bonding step ,

〈도2〉와 같이 bubble형태의 기체를 포함한 액체는 압력펌프 ( 1 ) 를 거쳐 압력탱크 ( 2 ) 하부에 도달하면 부력에 의해 기액분리가 이루어진다.As shown in FIG. 2, the liquid containing the bubble-shaped gas reaches the lower portion of the pressure tank (2) through the pressure pump (1), and gas-liquid separation is performed by buoyancy .

기액분리는 하단 첫 번째 기체모음판 ( 8 )부터 기체를 채우고 상하 통로를 거쳐 두번째 기체모음판( 8 )에 도달해 계속해서 기체를 채운다.Gas-liquid separation fills gas from the first gas collection plate (8) at the bottom, and reaches the second gas collection plate (8) through the up and down passages to continue filling gas.

기체가 압력탱크 ( 2 ) 상단 수위센서 ( 3 ) 까지 도달하면 수위가 B점까지 하강하여 수위센서 ( 3 )의 검침봉 (나) (다)가 물에 의해 전기적 개방되어 수위조절기가 멈춘다. 그로인해 전자변 ( 5 )이 개방, 날름변 ( 6 )이 폐쇄되어 기체유입이 중단되고 액체유입만 지속된다.When the gas reaches the pressure tank (2), the top level sensor (3), the water level drops to point B, and the meter reading rod (B) (C) of the level sensor (3) is electrically opened by water, which stops the level controller . As a result, the electron valve (5) is opened and the cutting edge (6) is closed so that the gas flow is stopped and only the liquid flow is maintained.

이렇게 압력탱크 ( 2 ) 에 유입된 기체와 액체는 기체모음판 ( 8 ) 에 의해 층 분리되고, 층 분리된 기체층사이를 통해 액체가 흐른다. 이것은 단위시간에 많은 양의 기체와 액체가 계면결합 할 때 필요한 접촉시간과 접촉면적을 확보할 수 있는 장치의 구성이다.The gas and liquid introduced into the pressure tank 2 are separated into layers by the gas collection plate 8, and the liquid flows through the separated gas layers. This is a device that can secure the contact time and the contact area required when a large amount of gas and liquid interfacially bond in a unit time.

계면결합은 이렇게 기체와 액체가 계면결합 압력 ( 2 7 5 KPa)을 유지하며 액체 속에 기체가 용해되어 기액포화액이 된다. 이 기액포화액은 압력탱크( 2 ) 내에서 계면결합압력 ( 2 7 5 KPa)을 받으면 기체와 액체의 접촉경계면에 계면을 중심으로 자리한 경막의 저항을 줄인다. 이때 액체 속으로 용해된 기체는 매우 작아 눈에 보이지 않는다. (참고2)In the interfacial bonding, the gas and the liquid maintain the interfacial bonding pressure (2 7 5 KPa) , and the gas is dissolved in the liquid to form a gas -liquid saturated liquid . When the gas-liquid saturated liquid is subjected to interfacial bonding pressure (2 7 5 KPa) in the pressure tank (2), it reduces the resistance of the dura film centered on the interface at the interface between the gas and the liquid . The gas dissolved into the liquid is very small and invisible. (Note 2)

산업적으로 단시간에 많은 물량의 계면결합수가 필요할 경우 기체와 액체의 계면접촉면적과 계면접촉시간이 많아야 된다.When industrially required a large amount of interfacial water in a short time, the interfacial contact area and the interfacial contact time of gas and liquid should be large.

본 발명은 압력탱크 ( 2 ) 내에 기체모음판 ( 8 ) 을 설치해, 기체층을 상하 겹겹이 두고, 상하 유체통로를 좌우 번갈아 배치하여 액체가 기체층을 따라 지그재그로 흐름으로서 계면접촉면적과 계면접촉시간이 많아 단시간에 많은 물량의 계면결합수를 생산할 수 있다.According to the present invention, the gas collection plate 8 is installed in the pressure tank 2, the gas layers are stacked up and down, and the upper and lower fluid passages are alternately arranged left and right, so that the liquid flows in a zigzag pattern along the gas layer. Many can produce a large amount of interfacial water in a short time.

이 계면결합수는 압력조절기 ( 7 ) 를 거쳐 산기구 없이 pond로 보내져 상압에 도달하면 액체부피 전체에서 미세기포를 발생한다.This interfacial water is sent through a pressure regulator (7) to a pond without an diffuser , and when atmospheric pressure is reached, microbubbles are generated throughout the liquid volume .

이렇게 pond내에서 발생된 미세기포는 부력이 거의 없어 수평적 부유상태로 확산되며, pond 전체가 등압으로 확산되기 때문에 미세기포의 pond내 체류시간이 매우 길다.This micro-bubbles generated within the pond is spread by horizontal floating almost buoyant gone, because the whole pond will be spread in the residence time in the pond of isobaric microbubbles very long.

그 외 구성품으로 전자변 ( 5 ) 은 액체용 Solenoid Valve로서 기액혼합 시 액체의 통로를 폐쇄하여 압력펌프( 1 )의 흡입양정력(0 . 8 KPa)을 날름변 ( 6 ) 에 작용케 하는 전기적 Valve.In other components, the solenoid valve (5) is a solenoid valve for liquids. It is an electric valve that closes the passage of liquid during gas-liquid mixing and acts the suction lift force (0.8 KPa) of the pressure pump (1) on the cutting edge (6). .

날름변 ( 6 )은 기체용 Check Valve로서 기액혼합 시 압력펌프( 1 )의 흡입양정력 (0 . 8 KPa)으로 기체의 통로를 개방하는 기계적 Valve.The cutting edge (6) is a check valve for gas. It is a mechanical valve that opens the gas passage with the suction lifting force (0.8 KPa) of the pressure pump (1) during gas-liquid mixing.

제어함 ( 4 ) 은 수위조절기와 Time Relay 및 전기적 Control Box로 구성.The control box (4) consists of a level controller, a time relay and an electrical control box.

압력조절기 ( 7 )는 수동식 반고정 Valve로서 압력탱크 ( 2 ) 내의 압력 (2 7 5 KPa)을 유지하기 위한 것이다.The pressure regulator (7) is a manual semi-locking valve for maintaining the pressure in the pressure tank (2 7 5 KPa).

압력탱크 ( 2 ) 는 내부에 기체모음판 ( 8 ) 을 내장한 원주형 밀폐탱크로서 입력측에 압력펌프( 1 )와 출력측에 압력조절기 ( 7 ) , 압력지시계, 상부에 수위조절기를 포함한 계면결합용 압력탱크이다.The pressure tank (2) is a cylindrical closed tank having a gas collection plate (8) inside. The pressure for interfacial coupling including a pressure pump (1) on the input side and a pressure regulator (7) on the output side, a pressure indicator, and a water level regulator on the top. It's a tank.

본 발명은 액체에 기체를 효율적으로 결합시켜, 액체 사용 목적을 최대 효율화 함에 있다.The present invention is to efficiently combine the gas to the liquid, to maximize the purpose of the liquid use.

물의 경우 양식장의 산소포화, 수질개선, 살균, 약품첨가, 제3의 이용수 창출 등이 가능하며, 다른 액체도 특수 기체를 결합시켜 제3의 액체 창출이 가능하다.In the case of water, it is possible to saturate the farm, improve the water quality, sterilize, add chemicals, and create a third use water, and other liquids can also create a third liquid by combining special gases.

본 발명은 미세기포의 크기(산기시:3-5m/m, 계면결합시;0.03-0.05m/m)를 미분화하므로 용존산소(Do)의 효율은 기체의 용해율 내에서 최대의 효율을 산출할 수 있다. 총 미세기포 면적(ΣA)은 기포크기 비율(Rm)에 역비례하여 ΣA=1/Rm, 용존산소(Do)의 효율은 K*ΣA*T이며, (K;용해율, T;체류시간) 이는 기포의 크기를 산기식의 1 / 1 0 0로 분할하면, 용해율 범위 내에서 ΣA=100배,T=1000배 이상일 때, 100,000배의효율을 얻는다. 고로, 기포의 크기를 쪼개, (5 0 μ정도) 초미세기포를 만들면 부력이 거의 작용치 않아 체류시간 (T)이 산기식의 1000배 이상이 되어 무한한 결합효율을 산출할 수 있다.The present invention micronizes the size of the microbubbles (acidity: 3-5m / m, interfacial bonding; 0.03-0.05m / m), so the efficiency of dissolved oxygen (Do) can yield the maximum efficiency within the gas dissolution rate. Can be. The total microbubble area (ΣA) is inversely proportional to the bubble size ratio (Rm), and the efficiency of ΣA = 1 / Rm and dissolved oxygen (Do) is K * ΣA * T, where (K; dissolution rate, T; residence time) If the size of is divided by 1/1 0 of the acid formula, 100,000 times efficiency is obtained when ΣA = 100 times and T = 1000 times or more within the dissolution rate range. Therefore, if the size of the bubble is broken down (about 5 0 μ) to make an ultra-fine foam, the buoyancy is hardly applied, and the residence time (T) is more than 1000 times of the acidic formula, and thus infinite coupling efficiency can be calculated.

또한 초기 유입수단계에 물리적 여과단계를 두고, 최종단계에 생물학적, 화학적 여과단계를 설치하여 하수처리장 등 산업에 이바지 하는 효과를 갖는다.In addition, the physical infiltration stage is placed in the initial influent stage, and biological and chemical filtration stages are installed in the final stage, which contributes to industries such as sewage treatment plants.

또한 pond내에 산기구 없이 방출하여 액체의 출렁임과 기체의 분사 소음이 없어 양식어의 스트레스 해소와 미세오니의 침전작용에 유용하다.In addition, it is useful for relieving stress of fish and sedimentation of micro sludge because there is no squirt of liquid and no injection noise of gas because it is discharged without acid apparatus in pond.
