비말 방지 기액 접촉 장치Anti-splash gas-liquid contact device
본 발명은 기체와 액체가 접촉하는 구조를 포함하는 비말 방지 기액 접촉 장치에 대한 것이다. The present invention relates to an anti-splash gas-liquid contact device including a structure in which gas and liquid contact each other.
기체액체접촉에 의한 방식으로는 분무, 접촉, 투과등의 방식으로 기체와 액체의 접촉효율을 향상시키기 위한 방법이 모색되어 이용하고 있다.As a method by gas-liquid contact, a method for improving the contact efficiency of gas and liquid in a method such as spraying, contact, permeation, etc. has been sought and used.
액체를 이용하여 기체의 조건(온도, 습도, 가스상 오염 물질, 입자상오염물질, 방사선물질, 세균, 바이러스 등)과 기체를 이용하여 액체의 처리(산화, 용존농도조절, 수분조절, 온도조절, 살균 등)를 할 경우 정해진 장치의 면적 혹은 체적과 공간에서 희망하는 기체와 액체의 접촉 효율을 극대화하여야 한다.Gas conditions (temperature, humidity, gaseous pollutants, particulate pollutants, radioactive materials, germs, viruses, etc.) and treatment of liquids (oxidation, dissolved concentration control, moisture control, temperature control, sterilization) using liquids etc.), it is necessary to maximize the contact efficiency of the desired gas and liquid in the area or volume and space of the device.
액체와 기체의 접촉효율을 극대화 하기 위해서 기체의 풍속과 액체의 유속과 유량을 확대하고, 액체를 노즐 분사 혹은 여러 방법으로 접촉장치에 흐르게 하여 접촉작용을 극대화하는 기술이 개발되고 있는데, 이때 액체가 비산하여 공기와 함께 토출되어 본래 목적하는 조건의 제어 이외의 액체 오염과 액체비산에 의한 2차오염 등의 큰 문제를 야기한다. 이는 생산제품에 혼입되어 품질저하를 야기하고, 거주 체류공간의 공기조화에서는 비산오염을 야기하여 호흡기에 흡입되는 문제를 발생시킨다.In order to maximize the contact efficiency between liquid and gas, a technology is being developed to maximize the contact action by increasing the wind speed of the gas and the flow rate and flow rate of the liquid, and flowing the liquid through the contact device through nozzle spraying or various methods. At this time, the liquid It scatters and is discharged together with air, causing big problems such as liquid contamination other than the control of originally intended conditions and secondary contamination by liquid scattering. It is mixed with manufactured products to cause quality deterioration, and in the air conditioning of the residence space, it causes scattering pollution, causing a problem of being inhaled into the respiratory system.
이러한 문제를 해결하기 위하여 후단필터를 적용하여 사후 제거하는 방식을 주로 적용할 수 있으나, 후단필터의 적용은 정압손실 등으로 장치의 비대화와 높은 정압손실에 의한 에너지 과다소비, 소음 진동 등의 많은 문제를 야기한다. 또한 후단필터는 액체의 비산이나 비말의 완벽한 원천적인 해결도 불가능하다.In order to solve this problem, a post-removal method by applying a post-filter can be mainly applied, but the application of a post-filter causes many problems such as enlargement of the device due to static pressure loss, excessive energy consumption due to high static pressure loss, noise and vibration, etc. cause In addition, the post-filter cannot completely solve the problem of splashing or droplets of liquid.

액체 탱크(50)는 상기 기액 접촉 셀(10)을 통과한 액체가 저장되는 탱크 본체(51)와 상기 탱크 본체(51) 내부에 배치되며, 액체(F)보다 비중이 가벼워 액체에 뜨는 재질의 다공성 매체(52), 예를 들면 스펀지를 포함하며, 상기 탱크 본체(51)의 하부에는 액체 공급 라인의 연결관이 연결되어, 상기 탱크 본체(51)의 액체(F)가 펌프(60)를 통하여 다시 상부의 기액 접촉 셀(10)의 공급 자켓(11)으로 공급된다. 다공성 매체(52)는 액체 탱크(50) 내부의 유동을 방지하여 탱크에서의 비말형성을 방지할 수 있으며, 혹시 있을 기액 접촉 셀(10)로부터의 물방울 낙하로 인한 추가 비말 형성을 차단한다. The liquid tank 50 is disposed inside the tank body 51 in which the liquid that has passed through the gas-liquid contact cell 10 is stored and is disposed inside the tank body 51, and is made of a material that floats on the liquid because its specific gravity is lighter than that of the liquid F. It includes a porous medium 52, for example, a sponge, and a connection pipe of a liquid supply line is connected to the lower part of the tank body 51 so that the liquid F of the tank body 51 passes through the pump 60. Through this, it is again supplied to the supply jacket 11 of the upper gas-liquid contact cell 10. The porous medium 52 can prevent the formation of droplets in the tank by preventing the flow inside the liquid tank 50, and also prevents the formation of additional droplets due to possible droplets falling from the gas-liquid contact cell 10.
한편, 기액 접촉 셀(10)의 기액 접촉 구조(14)는 탱크 본체(51)에 저장된 액체(F)에 일부분이 접촉되도록 길이를 가지며, 따라서, 기액 접촉 구조(14)를 통과한 액체(F)는 비말이 되어 탱크 본체(51)로 들어가지 않을 수 있다. On the other hand, the gas-liquid contact structure 14 of the gas-liquid contact cell 10 has a length such that a part of it comes into contact with the liquid F stored in the tank body 51, and therefore, the liquid F passing through the gas-liquid contact structure 14 ) may become droplets and not enter the tank body 51.
펌프(60)는 액체 공급 라인에 배치되며, 탱크 본체(51) 내부의 액체(F)를 상기 기액 접촉 셀(10)의 공급 자켓(11)으로 공급한다. 펌프(60)의 전단에는 액체(F)의 이물을 거르는 필터가 배치될 수 있다. The pump 60 is disposed in the liquid supply line and supplies the liquid F inside the tank body 51 to the supply jacket 11 of the gas-liquid contact cell 10. A filter for filtering foreign substances of the liquid F may be disposed at a front end of the pump 60 .
한편, 도시하지는 않았지만, 상기 액체 공급 라인에는 공기와의 접촉에 의해서 증발되는 액체를 보충할 수 있도록 액체 공급부가 연결될 수 있다. 액체 공급은 공급라인에 직접 연결될 수도 있지만, 사용자가 직접 공급하는 것도 가능함은 물론이다. 또한, 액체 공급 라인에는 액체의 유속을 측정하는 유속 센서(62) 혹은 유량 센서가 배치될 수도 있다. 이러한 유속/유량 센서는 제어부(90)에 연결되며, 펌프(60)에 의해서 순환되는 액체의 양을 정확하게 제공한다. Meanwhile, although not shown, a liquid supply unit may be connected to the liquid supply line to replenish liquid evaporated by contact with air. The liquid supply may be directly connected to the supply line, but it is also possible that the user directly supplies it. In addition, a flow rate sensor 62 or a flow rate sensor for measuring the flow rate of the liquid may be disposed in the liquid supply line. This flow rate/flow sensor is connected to the controller 90 and provides an accurate amount of liquid circulated by the pump 60.
기액 접촉 셀(10)의 전방 및 후방에는 공기압을 측정하는 공기 압력 센서(71, 72)가 배치될 수 있다. 공기 압력 센서(71, 72)는 제어부(90)에 연결되며, 기액 접촉 셀(10)에서의 압력 손실을 측정하며, 공급되는 풍속을 측정한다. 제어부(90)는 공기 압력 센서(71, 72)의 측정값에 근거하여 상기 팬(40)을 제어할 수 있다. Air pressure sensors 71 and 72 for measuring air pressure may be disposed in front and rear of the gas-liquid contact cell 10 . The air pressure sensors 71 and 72 are connected to the control unit 90 and measure a pressure loss in the gas-liquid contact cell 10 and a supplied wind speed. The controller 90 may control the fan 40 based on the measured values of the air pressure sensors 71 and 72 .
제어부(90)는 압력 센서(71, 72), 유속 센서(62), 펌프(60) 및 팬(40)에 연결되어, 기액 접촉 셀(10)에 일정한 액체막을 유지하게 하여, 비말이 발행되지 않도록 기체/액체 공급비를 조절한다. 액체와 기체간의 접촉작용 최적화를 위한 액체/기체 비율, 액기비 비율(sol(kg/h)/air(kg/h))을 0.1 ~ 1.5 이내에서 기체의 종류와 액체의 종류에 따라 다르게 설정될 수 있다. 제어부(90)는 상기 범위의 액기비에서 기체와 액체의 종류에 따라서 목표치를 정하고, 그에 맞게 액체 공급량 및 기체 공급량을 조절한다. 이때, 제대로 공급되고 있는지를 상기 센서를 통하여 점검하면서 추종 제어한다. The control unit 90 is connected to the pressure sensors 71 and 72, the flow sensor 62, the pump 60 and the fan 40 to maintain a constant liquid film in the gas-liquid contact cell 10 so that no droplets are issued. Adjust the gas/liquid supply ratio so that The liquid/gas ratio and liquid-gas ratio (sol(kg/h)/air(kg/h)) for optimizing the contact action between liquid and gas can be set differently depending on the type of gas and liquid within 0.1 to 1.5. can The control unit 90 sets a target value according to the type of gas and liquid in the liquid-to-liquid ratio within the above range, and adjusts the liquid supply amount and the gas supply amount accordingly. At this time, follow-up control is performed while checking whether supply is properly performed through the sensor.
제어부(90)는 기액 접촉 셀(10)에서 풍속이 1.5㎧ ~ 2.5㎧ 범위가 되도록 팬(40)을 제어한다. 기체의 풍속은 접촉 작용을 크게하나, 기체의 풍속이 높아지는 경우에 기액 접촉 셀(10)의 액체막이 비산될 수 있다. 구체적으로, 1.5㎧ 미만에서는 액체의 표면장력을 극복하고 비산을 일으킬 수 없어 비산에는 유리하나 접촉작용이 미약하고 입자등의 질량물을 가속하여 액체와 충돌시킬 수 없고, 2.5㎧ 초과서는 접촉작용에 유리하지만, 액체의 표면평형을 깨트리고 접촉각을 크게하여 비산을 일으키기 쉬워 기액 접촉 셀(10)에서는 사용하지 않는다.The controller 90 controls the fan 40 so that the wind speed in the gas-liquid contact cell 10 is in the range of 1.5 m/s to 2.5 m/s. The wind speed of the gas increases the contact action, but when the wind speed of the gas increases, the liquid film of the gas-liquid contact cell 10 may be scattered. Specifically, less than 1.5㎧ can overcome the surface tension of the liquid and cannot cause scattering, so it is advantageous for scattering, but the contact action is weak, and mass objects such as particles cannot be accelerated to collide with the liquid. Although advantageous, it is not used in the gas-liquid contact cell 10 because it breaks the surface equilibrium of the liquid and increases the contact angle to cause scattering.
제어부(90)는 상기 압력 센서(71, 72)를 통하여 기액 접촉 구조(14)의 압력 손실을 측정하는 것도 가능하다. 압력 손실의 측정은 팬 조절에 활용될 뿐만 아니라, 차압이 변화되는 경우에 기액 접촉 셀(10)의 오염 및 액체막의 불균형을 예상할 수 있으므로, 사용자에게 알림을 주는 것도 가능하다. The controller 90 may also measure the pressure loss of the gas-liquid contact structure 14 through the pressure sensors 71 and 72 . The measurement of the pressure loss is not only used for controlling the fan, but also can give a notification to the user because contamination of the gas-liquid contact cell 10 and imbalance of the liquid film can be predicted when the differential pressure is changed.
도 3 내지 8 에는 본 발명의 일실시예에 따른 비말 방지 기액 접촉 장치(100)의 기액 접촉 셀(10)이 자세히 도시되어 있다. 구체적으로, 도 3 에는 본 발명의 일실시예에 따른 비말 방지 기액 접촉 장치의 기액 접촉 셀에서 자켓 내부 사진이 도시되어 있으며, 도 4 에는 본 발명의 일실시예에 따른 기액 접촉 셀의 개략 사시도가 도시되어 있고, 도 5 에는 본 발명의 다른 실시예에 따른 기액 접촉 셀의 다른 실시예의 개략 사시도가 도시되어 있으며, 도 6 에는 본 발명의 일실시예에 따른 비말 방지 기액 접촉 장치의 기액 접촉 셀에서 심지관 표면의 개략 확대도가 도시되어 있다. 도 7 에는 본 발명의 일실시예에 따른 비말 방지 기액 접촉 장치의 기액 접촉 셀의 개략도가 도시되어 있으며, 도 8 에는 도 7 의 A의 확대도가 도시되어 있다. 3 to 8 show the gas-liquid contact cell 10 of the anti-splash gas-liquid contact device 100 according to an embodiment of the present invention in detail. Specifically, FIG. 3 shows a picture of the inside of a jacket in a gas-liquid contact cell of an anti-splash gas-liquid contact device according to an embodiment of the present invention, and FIG. 4 is a schematic perspective view of the gas-liquid contact cell according to an embodiment of the present invention. 5 is a schematic perspective view of another embodiment of a gas-liquid contact cell according to another embodiment of the present invention, and FIG. 6 is a gas-liquid contact cell of an anti-splash gas-liquid contact device according to an embodiment of the present invention. A schematic enlarged view of the wick tube surface is shown. 7 is a schematic diagram of a gas-liquid contact cell of an anti-splash gas-liquid contact device according to an embodiment of the present invention, and FIG. 8 is an enlarged view of A of FIG. 7 .
도 3 에서 보이듯이, 기액 접촉 셀(10)에서 액체 공급관(12)은 공급 자켓(11) 내부에서 수평 방향으로 연장하며, 상기 액체 공급관(12)은 공급 자켓(11)의 내부에서 일정 간격으로 구멍이 형성되어, 액체가 상기 구멍을 통하여 자켓(11)내부로 유입된다. 이렇게 공급되는 액체는 자켓 하부의 필터 부재(13)의 다공성 구조로 인한 모세관 현상, 막투과 및 자중에 의해서 하부에 연결된 기액 접촉 구조(14)로 흘러간다. As shown in FIG. 3, in the gas-liquid contact cell 10, the liquid supply pipe 12 extends horizontally inside the supply jacket 11, and the liquid supply pipe 12 extends inside the supply jacket 11 at regular intervals. A hole is formed, and the liquid flows into the inside of the jacket 11 through the hole. The liquid supplied in this way flows into the gas-liquid contact structure 14 connected to the lower part by capillary action due to the porous structure of the filter member 13 at the lower part of the jacket, membrane permeation, and its own weight.
공급 자켓(11)은 주변으로 공기의 유로가 형성되지 않도록 기체 차폐를 위한 차폐제를 구비하여 하면의 필터 부재(13)를 제외한 다른 경로로는 액체가 유출되지 않게 실링될 수 있다. The supply jacket 11 may be provided with a shielding material for shielding gas so that an air flow path is not formed around the supply jacket 11 so that liquid does not flow out through other paths except for the filter member 13 on the lower surface.
기액 접촉 구조(14)는 표면에서 일정한 액체막 두께를 유지할 수 있다면 도 1 에 도시된 바와 같이 종래의 기액 접촉 구조(14)를 사용하는 것도 가능하다. 즉, 종래의 기액 접촉 구조(14)에 상기 필터 부재(13)를 통하여 일정량의 액체를 공급해주는 경우에 일정한 액체막이 형성/유지될 수 있는 구조라면 적용가능하다. 이때, 액체막은 0.1~0.5㎜ 의 두께를 가지는 것이 바람직하다. 액체막의 두께는 기액 접촉 셀(10) 비표면에서의 접촉작용을 최적화하기 위한 기체와의 직접접촉하는 물질로서, 0.1㎜ 미만일 경우는 액체막 두께가 너무 작아서 표면의 액체량이 적어 접촉작용에 의한 물질교환 짧은 시간에 포화되어 접촉효율이 저하될 뿐만 아니라, 신선액체의 공급이 원활하지 않게 된다. 0.5㎜ 초과일 경우는 충분한 신선액체의 공급이 원활하여 물질교환이 용이하고 접촉작용이 극대화 될 수 있으나 액체막의 두께가 너무 두터워서 중력에 의한 자연낙하, 미세공극의 채움, 미세돌기의 채움 등의 모세관현상을 이용한 기액 접촉 셀의 표면을 흐르는 액체의 유속을 통제할 수 없어, 자연낙하 폭포, 접촉각의 증대 등에 의한 액체의 비산을 유발하게 된다.As for the gas-liquid contact structure 14, it is also possible to use a conventional gas-liquid contact structure 14 as shown in FIG. That is, any structure capable of forming/maintaining a certain liquid film when a certain amount of liquid is supplied to the conventional gas-liquid contact structure 14 through the filter member 13 is applicable. At this time, the liquid film preferably has a thickness of 0.1 to 0.5 mm. The thickness of the liquid film is a material that is in direct contact with the gas to optimize the contact action on the specific surface of the gas-liquid contact cell 10. If the thickness is less than 0.1 mm, the liquid film thickness is too small and the amount of liquid on the surface is small, so the material is exchanged by the contact action. It is saturated in a short time and the contact efficiency is lowered, and the supply of fresh liquid is not smooth. If it exceeds 0.5mm, enough fresh liquid can be supplied smoothly, so material exchange is easy and contact action can be maximized. Since the flow rate of the liquid flowing on the surface of the gas-liquid contact cell using the phenomenon cannot be controlled, scattering of the liquid occurs due to a natural fall waterfall, an increase in the contact angle, and the like.
기액 접촉 구조(14)의 소재는 종이, 섬유, 부직포, 다공성 물질, 필터, 목재나 제올라이트 등의 천연물질, 화학물질이나 조직일 수 있으며, 해당 소재에 카본코팅, 제올라이트 코팅 등 친수성 표면 코팅을 할 수도 있다. 기액 접촉 구조(14)의 표면에는 미세구조의 돌기 요철,모세관, 공극 등에 의하여 친수성 표면이 형성되고 그 친수성 미세 돌기나 요철 공극에는 액체가 채워지므로 평형접촉각은 매우 작아 60도 이하가 되어 기체에 의한 비산이나 수적의 발생 방지할 수 있다. The material of the gas-liquid contact structure 14 may be paper, fiber, non-woven fabric, porous material, filter, natural material such as wood or zeolite, chemical material or tissue, and a hydrophilic surface coating such as carbon coating or zeolite coating may be applied to the material. may be On the surface of the gas-liquid contact structure 14, a hydrophilic surface is formed by microstructure protrusions, capillaries, and pores, and since the hydrophilic microprotrusions or concavo-convex voids are filled with liquid, the equilibrium contact angle is very small and is less than 60 degrees, so that the gas Scattering and water droplets can be prevented.
또한, 앞에서 말한 바와 같이, 기액 접촉 구조(14)는 탱크의 액체(F) 안쪽까지 연장되므로, 액체 흐름의 단절이나 경사 등에 의한 낙차, 중력가속으로 인한 날림이나 수적, 폭포현상에 의한 기포 비산 등이 발생하지 않는다. In addition, as mentioned above, since the gas-liquid contact structure 14 extends to the inside of the liquid F in the tank, drop due to disconnection or inclination of the liquid flow, splashing or droplets due to gravity acceleration, bubble scattering due to waterfall, etc. this doesn't happen
기액 접촉 구조(14)는 연직 방향으로 연장형성되는데, 연직 방향이 아니라 연직 방향에 대하여 경사진 방향으로 연장형성되는 것도 가능하다. 다만, 이 경우에도 경사각은 경사면을 따라서 액체가 표면으 따라서 타고 흐를 수 있는 정도에 제한된다. The gas-liquid contact structure 14 extends in the vertical direction, but it is also possible to extend in a direction inclined to the vertical direction instead of the vertical direction. However, even in this case, the angle of inclination is limited to the degree to which the liquid can flow along the surface along the inclined surface.
도 4 및 도 5 에는 기액 접촉 셀(10)의 실시예가 도시되어 있다. 도 4 에서 보이듯이, 기액 접촉 셀(10)은 상부에 공급 자켓(11)이 배치되며, 상기 공급 자켓(11)로 액체 공급 라인에 연결된 액체 공급관(12)이 연결된다. 공급 자켓(11)의 하면에는 필터패드(13)이 배치되며, 필터 패드(13)의 하부에 기액 접촉 구조(14)가 배치된다. 4 and 5 show an embodiment of a gas-liquid contact cell 10 . As shown in FIG. 4, the gas-liquid contact cell 10 has a supply jacket 11 disposed thereon, and a liquid supply pipe 12 connected to a liquid supply line is connected to the supply jacket 11. A filter pad 13 is disposed on the lower surface of the supply jacket 11, and a gas-liquid contact structure 14 is disposed under the filter pad 13.
도 4 에서는 기액 접촉 구조(14)는 수평 단면이 유선형 형상을 가지는 다공성 구조의 소재로 기둥형상으로 형성된다. 기액 접촉 구조(14)는 종이, 섬유, 부직포, 다공성 물질, 필터, 목재나 제올라이트 등의 천연물질, 화학물질이나 조직일 수 있으며, 심지관이라고 할 수 있다. 심지관은 상하 방향으로 연장하며, 복수개가 필터 패드(13)의 하부에 복수의 열을 이루어 배치된다. 심지관은 복수의 열로 배치되며, 이웃하는 열에서 상기 심지관은 서로 엇갈려 배치된다. 심지관은 액체의 자유낙하흐름을 제어하며, 공기 흐름에 고른 접촉 효율을 얻을 수 있다. 이 실시예에서, 심지관의 수평 단면 형상은 대략 다이아몬드 형상이나, 이에 제한되는 것은 아니며 타원형, 원형, 각형등 공기흐름에 적합한 형상을 가질 수 있다. In FIG. 4 , the gas-liquid contact structure 14 is formed in a columnar shape with a porous material having a streamlined horizontal section. The gas-liquid contact structure 14 may be paper, fiber, nonwoven fabric, porous material, filter, natural material such as wood or zeolite, chemical material or tissue, and may be referred to as a wick tube. The wick tube extends in the vertical direction, and a plurality of wick tubes are arranged in a plurality of rows under the filter pad 13 . The wick tubes are arranged in a plurality of rows, and the wick tubes in adjacent rows are staggered with each other. The wick tube controls the free-falling flow of the liquid and can obtain even contact efficiency with the air flow. In this embodiment, the horizontal cross-sectional shape of the wick tube is approximately a diamond shape, but is not limited thereto, and may have an elliptical, circular, or angular shape suitable for air flow.
심지관은 상하 방향의 길이가 상기 공급 자켓(11)로부터 탱크 본체(51) 내측저면까지의 거리보다는 짧게 형성되되, 상기 액체(F)의 상면까지의 거리보다는 길게 형성되어 상기 심시관은 액체(F)에 담길 수 있도록 구성된다. 일예로, 심지관은 탱크 본체(51) 내측저면으로부터 5~10㎜ 정도 떨어지게 연장될 수 있다. The wick pipe has a length in the vertical direction shorter than the distance from the supply jacket 11 to the inner bottom surface of the tank body 51, but is formed longer than the distance to the upper surface of the liquid F, so that the wick tube is liquid ( It is configured so that it can be contained in F). For example, the wick tube may extend about 5 to 10 mm away from the inner bottom surface of the tank body 51 .
심지관의 표면에는 액체의 청정도 유지를 위한 필터기능을 갖으며 필터의 정화기능을 위하여 카본, 제올라이트, 활성탄, 분자 흡착제등의 선택적 코팅이 수행되는 것도 가능하다. The surface of the wick tube has a filter function for maintaining the cleanliness of the liquid, and it is possible to perform selective coating of carbon, zeolite, activated carbon, molecular adsorbent, etc. for the purification function of the filter.
또한, 심지관의 표면은 미세 돌기가 형성될 수도 있으며, 이러한 모습은 도 6 에 도시되어 있다. 도 6 에서 보이듯이, 기액 접촉 구조(14)인 심지관의 표면에는 미세 돌기(14b)가 형성될 수 있으며, 이러한 돌기에 의해서 액체(F)가 심지관의 표면에 고르게 분포될 수 있다. 이때, 액체가 미세 돌기(14b)의 모세관 현상에 의한 표면 접촉각(θ)이 60도 이하인 것이 바람직하다. 여기서 접촉각이란, 액체가 미세 돌기(14b)에 있을 때 평형을 이뤘을 때의 각을 의미한다. 접촉각이 90도 이하인 경우에 친수성, 90도 초과인 경우에 소수성으로 구분하는데, 기액 접촉 셀(10)은 불안정한 상태에서 가동되므로, 평형 접촉각이 60도 이하로 안정적인 상태에 되어야 미세 돌기(14b)에 채워지는 액체가 음각의 접촉각을 가져서 비산의 문제로부터 안전하게 된다. In addition, fine protrusions may be formed on the surface of the wick tube, and this appearance is shown in FIG. 6 . As shown in FIG. 6, fine protrusions 14b may be formed on the surface of the wick tube having a gas-liquid contact structure 14, and the liquid F may be evenly distributed on the surface of the wick tube by these protrusions. At this time, it is preferable that the surface contact angle (θ) of the liquid is 60 degrees or less due to the capillarity of the fine protrusions 14b. Here, the contact angle means an angle when the liquid is in equilibrium when it is present on the fine protrusions 14b. If the contact angle is less than 90 degrees, it is classified as hydrophilic, and if it exceeds 90 degrees, it is classified as hydrophobic. Since the gas-liquid contact cell 10 operates in an unstable state, the equilibrium contact angle must be in a stable state of 60 degrees or less to form fine protrusions 14b. The liquid to be filled has a negative contact angle, making it safe from splashing.
미세 돌기(14b)가 없는 경우에도 기액 접촉 구조(14)의 미세 공극에서의 접촉각은 60도 이하인 것이 바람직하다.Even in the case where there are no fine protrusions 14b, the contact angle in the fine pores of the gas-liquid contact structure 14 is preferably 60 degrees or less.
도 5 에는 기액 접촉 셀(10)의 다른 실시예가 도시되어 있다. 도 5 의 경우에 도 4 와 유사하게 기액 접촉 구조(14)는 수평 단면이 유선형 형상을 가지는 다공성 구조의 소재로 기둥형상으로 형성된다. 기액 접촉 구조(14)는 종이, 섬유, 부직포, 다공성 물질, 필터, 목재나 제올라이트 등의 천연물질, 화학물질이나 조직일 수 있으며, 심지관이라고 할 수 있다. 심지관은 상하 방향으로 연장하며, 복수개가 필터 패드(13)의 하부에 복수의 열을 이루어 배치된다. 심지관은 내부에 내관(14a)이 형성되며, 필터 부재(13)를 통과한 액체는 내관(14a)으로 공급되어 내관(14a) 내벽을 따라 흐르면서 내관(14a) 주변의 심지부로 모세관현상 혹은 공극 흡수 현상을 통하여 표면으로 이동되어 공기와 접촉하게 된다.5 shows another embodiment of a gas-liquid contact cell 10 . In the case of FIG. 5, similar to FIG. 4, the gas-liquid contact structure 14 is formed in a columnar shape with a porous structure material having a streamlined horizontal cross section. The gas-liquid contact structure 14 may be paper, fiber, nonwoven fabric, porous material, filter, natural material such as wood or zeolite, chemical material or tissue, and may be referred to as a wick tube. The wick tube extends in the vertical direction, and a plurality of wick tubes are arranged in a plurality of rows under the filter pad 13 . An inner tube 14a is formed inside the wick tube, and the liquid passing through the filter member 13 is supplied to the inner tube 14a and flows along the inner wall of the inner tube 14a to the wick around the inner tube 14a, causing capillarity or voids. It moves to the surface through the absorption phenomenon and comes into contact with the air.
도 7 및 도 8 에는 본 발명에 따른 기액 접촉 셀(10)의 개략도가 도시되어 있다. 본 발명에 따른 기액 접촉 셀(10)에서 액체가 상부의 공급 자켓(11)에 공급되면, 액체는 필터 패드(13)를 통과하여 기액 접촉 구조(14)로 공급된다. 기액 접촉 구조(14)의 경우에 다공성 구조의 재질로 형성되어 있어서, 필터 패드(13)를 통과하여 배출되는 액체는 상기 기액 접촉 구조(14)를 타고 하부로 내려가게 된다. 필터 패드(13)는 모세관 투과막(13a)을 포함하여 상기 모세관 투과막(13a)을 통하여 일정한 액체가 기액 접촉 구조(14)로 스며들며, 이렇게 액체가 이동됨으로써 비말이 형성되지 않을 수 있다. 7 and 8 show schematic diagrams of a gas-liquid contact cell 10 according to the present invention. In the gas-liquid contact cell 10 according to the present invention, when liquid is supplied to the upper supply jacket 11, the liquid passes through the filter pad 13 and is supplied to the gas-liquid contact structure 14. Since the gas-liquid contact structure 14 is made of a porous material, the liquid discharged through the filter pad 13 goes down along the gas-liquid contact structure 14 . The filter pad 13 includes a capillary permeable membrane 13a so that a certain liquid permeates into the gas-liquid contact structure 14 through the capillary permeable membrane 13a, and droplets may not be formed as the liquid moves in this way.
이때, 기액 접촉 구조(14)의 표면에 액체막이 형성되게 되며, 이렇게 형성된 액체막과 상기 기액 접촉 셀(10)을 통과하는 공기가 만나면서 물질교환, 에너지교환, 화학 반응, 살균, 세정 등의 효과가 발생된다. 특히, 본 발명에서는 위와 같은 기액 접촉 셀(10)의 구조를 가지며, 액체의 공급량과 기체의 공급량이 조절되는 상태에서 기액이 접촉하기 때문에, 접촉 시 액체가 비산하지 않아서 비말이 형성되지 않으며, 필터 패드(13)를 통과한 액체도 기액 접촉 구조(14)를 타고 탱크(50)로 이동되기 때문에 비말 발생이 없다. 따라서, 비산 입자로 인한 초미세먼지의 생성이 없어서 액체에 특정 성분이 포함된다고 하더라도 인체에 영향을 끼칠 우려가 없다. At this time, a liquid film is formed on the surface of the gas-liquid contact structure 14, and as the liquid film thus formed and the air passing through the gas-liquid contact cell 10 meet, effects such as material exchange, energy exchange, chemical reaction, sterilization, and cleaning are achieved. occurs In particular, the present invention has the structure of the gas-liquid contact cell 10 as described above, and since the gas-liquid contacts in a state in which the supply amount of the liquid and the supply amount of the gas are controlled, the liquid does not scatter during contact and no droplets are formed, and the filter Since the liquid that has passed through the pad 13 is also moved to the tank 50 along the gas-liquid contact structure 14, there is no generation of droplets.
