미세기포펌프를 이용한 미세기포 혼합액체 발생장치{MICRO-BUBBLE SOLUTION GENERATING DEVICE USING TURBINE PUMP}MICRO-BUBBLE SOLUTION GENERATING DEVICE USING TURBINE PUMP}

본 발명은 미세기포펌프를 이용한 미세기포 혼합액체 발생장치에 관한 것으로서, 보다 상세하게는 와류가 발생하는 미세기포펌프에 액체와 기체를 동시에 투입하고, 임펠러의 회전에 의해 미세한 기포가 되도록 함으로써 액체와 기체가 골고루 혼합되도록 하는 미세기포펌프를 이용한 미세기포 혼합액체 발생장치에 관한 것이다.The present invention relates to a micro-bubble mixed liquid generating device using a micro-bubble pump, and more particularly to the liquid and gas to the micro-bubble pump to generate the vortex at the same time, by making the fine bubbles by the rotation of the impeller The present invention relates to a microbubble mixed liquid generator using a microbubble pump that allows gas to be evenly mixed.

물속에 녹아있는 이물질(화학물질, 고형유지(固形乳脂), 오염물질 등)을 제거하기 위해서 물속에 미세기포를 발생시켜 미세기포와 이물질이 결합하도록 하여 외부로 배출되도록 하는 기술이 개시되고 있다.In order to remove foreign substances (chemical substances, solid fats, contaminants, etc.) dissolved in water, a technique of generating micro-bubbles in water and allowing micro-bubbles and foreign substances to be discharged to the outside is disclosed.

미세기포와 결합된 이물질은 기포의 부력(浮力)에 의해 표면으로 떠오르게 되고, 표면에 모여진 물질을 제거함으로써 쉽게 오염수를 정화할 수 있다. 또한 액체 중에 녹아있는 유해한 기체와 액체를 좀 더 용해시키기 쉬운 기체로 변화시키고, 기체를 기화시킴으로써 오염원을 제거할 수도 있다.The foreign matter combined with the microbubbles are floated to the surface by buoyancy of the bubbles, and the contaminated water can be easily purified by removing the substances collected on the surface. It can also remove pollutants by converting harmful gases dissolved in liquids and liquids into more soluble gases and vaporizing them.

이와 같은 부상공법에 의한 오염 제거기술의 핵심이 되는 것이 미세기포를 발생시켜 오염수와 혼합하는 장치인데, 도 1은 종래기술에 따른 미세기포발생장치의 구성을 나타낸 개념도이다.The core of the decontamination technique by the flotation method is a device for generating micro-bubbles and mixing with contaminated water, Figure 1 is a conceptual diagram showing the configuration of a micro-bubble generating device according to the prior art.

종래기술에 따른 미세기포발생장치는 기체(공기)를 가압하여 투입하는 컴프레셔(102)와 액체(물)를 투입하는 가압펌프(108)를 포함하며, 컴프레셔(102)에서 나온 기체외 가압펌프(108)에서 나온 액체는 이젝터(106)에서 만나고 고정믹서(110)에서 균일하게 혼합된다.The microbubble generating device according to the prior art includes a compressor 102 for pressurizing a gas (air) and a pressurizing pump 108 for injecting a liquid (water), and an out-gas pressurized pump from the compressor 102 ( The liquid from 108 meets in the ejector 106 and is uniformly mixed in the fixed mixer 110.

이젝터(106)는 액체와 기체가 만나서 합류하는 지점이며, 고정믹서(110)는 스크류의 회전에 의해 액체와 기체가 와류를 일으키면서 혼합되는 곳이다. 고정믹서(110)를 나온 혼합액체는 압력탱크(112)에 들어가서 저장된다. 압력탱크(112)에는 압력 조절을 위한 밸브(114)가 구비되며, 내부의 압력을 측정하는 압력계(116)가 구비될 수 있다.The ejector 106 is a point where the liquid and gas meet and join, and the fixed mixer 110 is where the liquid and gas are mixed while causing the vortex by the rotation of the screw. The mixed liquid exiting the fixed mixer 110 is stored in the pressure tank 112. The pressure tank 112 is provided with a valve 114 for adjusting the pressure, it may be provided with a pressure gauge 116 for measuring the pressure inside.

압력탱크(112) 내부의 혼합액체는 액체 내부에 미세한 크기의 기포가 혼합되어 있는 형태를 가진다.The mixed liquid in the pressure tank 112 has a form in which bubbles of fine size are mixed in the liquid.

압력탱크(112)에서 나온 혼합액체는 운전탱크(124)로 이동하는데, 도중에 유입수저장탱크(120)에서 배출되는 유입수와 만나서 혼합된다.The mixed liquid from the pressure tank 112 is moved to the operation tank 124, and meets and mixes the inflow water discharged from the inflow water storage tank 120 on the way.

유입수는 오염물질이 혼합된 액체로서, 고형 또는 기체 상태의 이물질이 미세기포 혼합액체와 만나면서 이물질이 미세기포에 의해 운전탱크(124) 내부에서 부상하면서 제거된다. 운전탱크(124) 내부에 설치되는 노즐(126)에서는 고압의 혼합액체가 급격하게 감압되면서 분사되며, 이에 따라 다량의 미세기포가 운전탱크(124) 내부에 발생하게 된다.The inflow water is a liquid mixed with contaminants, and the solid or gaseous foreign matter meets the microbubble mixed liquid, and the foreign matter is removed while floating in the driving tank 124 by the microbubble. In the nozzle 126 installed inside the driving tank 124, the high pressure mixed liquid is injected while rapidly depressurizing, whereby a large amount of fine bubbles are generated in the driving tank 124.

운전탱크(124)의 일측에는 처리수배출구가 설치되며, 표면에 떠오른 오염물질을 배출하는 통로와 오염물질이 제거된 액체를 배출하는 통로가 구비되어 오염물과 액체를 분리하게 된다.One side of the driving tank 124 is provided with a treatment water outlet, and a passage for discharging the contaminant floated on the surface and a passage for discharging the liquid from which the contaminant is removed to separate the contaminant and the liquid.

일반적인 장치에서는 가압펌프(108)에서 배출되는 액체에 고압의 기체를 불어넣어서 섞이게 하고, 고정믹서(110)에서 스크류의 회전에 의해 기포를 미세하게 쪼개어서 미세기포가 생기게 하는 방식을 택하고 있다. 미세기포가 혼합된 액체는 대용량의 압력탱크(112)에 넣어서 보관하면서 유입수와 혼합한다.In the general apparatus, a high pressure gas is blown into the liquid discharged from the pressure pump 108 to be mixed, and fine bubbles are generated by splitting the bubbles finely by the rotation of the screw in the fixed mixer 110. The liquid mixed with microbubbles is mixed with the inflow water while being stored in a large-capacity pressure tank (112).

종래기술에서는 고압의 기체를 불어넣어야 하기 때문에 반드시 컴프레셔(102)가 필요하며, 미세기포를 생성하기 위한 고정믹서(110)와 미세기포 혼합액체를 유지하기 위한 압력탱크(112)가 필요하므로 설비가 대형화되고 이동설치가 어려운 문제점이 있었다.In the prior art, a compressor 102 is necessary because a high-pressure gas must be blown, and a fixed mixer 110 for generating microbubbles and a pressure tank 112 for holding a microbubble mixed liquid are required. There was a problem that it was difficult to install large and mobile.

이하에서 도면을 참조하여 본 발명의 실시예에 따른 "미세기포펌프를 이용한 미세기포 혼합액체 발생장치"(이하, '기포발생장치'라 함)를 설명한다.Hereinafter, with reference to the drawings will be described "micro bubble mixed liquid generator using a micro-bubble pump" (hereinafter referred to as "bubble generating device") according to the embodiment of the present invention.

도 2는 본 발명의 실시예에 따른 미세기포발생장치의 구성을 나타낸 개념도이다.2 is a conceptual diagram showing the configuration of a micro-bubble generating device according to an embodiment of the present invention.

본 발명의 기포발생장치는 미세기포펌프(202)에 액체와 기체를 동시에 투입하여 혼합과 미세기포의 발생이 동시에 이루어지도록 하며, 중간 압력탱크(208)에서 가압되었다가 운전탱크(220)에서 급격히 감압되면서 미세기포가 확산되도록 하는 것이 특징이다.In the bubble generator of the present invention, the liquid and gas are simultaneously introduced into the microbubble pump 202 so that the mixing and the generation of the microbubbles are simultaneously performed. It is characterized by allowing the microbubbles to diffuse while decompressing.

미세기포펌프(202)에는 액체와 기체가 투입되는 입구가 각각 형성되는데, 액체 투입라인에는 압력계(204)가 설치되어 투입되는 액체의 압력과 속도, 유량 등이 체크된다.The microbubble pump 202 is formed with an inlet through which liquid and gas are introduced, and a pressure gauge 204 is installed in the liquid inlet line to check the pressure, speed, and flow rate of the liquid to be introduced.

기체가 투입되는 입구에는 공기유량계(206)가 설치되어 기체의 압력과 속도, 유량 등을 체크한다.An air flow meter 206 is installed at the inlet of the gas to check the pressure, speed, and flow rate of the gas.

공기유량계(206)를 통과하여 미세기포펌프(202)에 들어온 기체는 미세기포펌프(202)의 회전에 의해 미세한 크기의 기포로 쪼개지면서 액체와 혼합된다. 미세기포가 혼합된 혼합액체는 압력탱크(208)에 들어가게 되며, 압력탱크(208)의 압력이 높아지면 배출밸브(210)가 열리면서 혼합액체의 일부가 빠져나가게 된다. 압력탱크(208) 내부의 압력은 바깥에 있는 압력계(212)에 의해 측정된다.The gas entering the microbubble pump 202 through the air flow meter 206 is mixed with the liquid while being split into bubbles of fine size by the rotation of the microbubble pump 202. The mixed liquid in which the microbubbles are mixed enters the pressure tank 208, and when the pressure of the pressure tank 208 is increased, the discharge valve 210 is opened so that a part of the mixed liquid is released. The pressure inside the pressure tank 208 is measured by an external pressure gauge 212.

혼합액체는 압력탱크(208) 내부에서 일정시간 동안 머무르면서 미세기포의 용해가 추가적으로 일어난다. 미세기포펌프(202)에서 배출되는 혼합액체는 상당한 압력을 가지고 있어서 압력탱크(208) 내부 역시 가압상태가 되어 미세기포의 용해가 더욱 용이해진다. 압력탱크(208)에는 별도의 가압장치가 설치되어 있어서 대기압보다 높은 상태로 혼합액체를 유지한다.While the mixed liquid stays in the pressure tank 208 for a predetermined time, dissolution of the microbubbles further occurs. The mixed liquid discharged from the microbubble pump 202 has a considerable pressure so that the inside of the pressure tank 208 is also pressurized, so that the microbubbles are more easily dissolved. The pressure tank 208 is provided with a separate pressurizing device to maintain the mixed liquid in a state higher than atmospheric pressure.

압력탱크(208) 내부의 혼합액체는 밸브(214)가 열리면서 바깥으로 나오게 되며, 운전탱크(220)로 이동하는 동안 외부의 유입수와 만나게 된다.The mixed liquid inside the pressure tank 208 comes out while the valve 214 is opened, and meets the external inflow water while moving to the operation tank 220.

유입수는 오염물질이 섞여있는 액체로서 유입수저장탱크(216)로부터 나와서 미세기포 혼합액체와 만난다. 유입수와 혼합된 미세기포 혼합액체는 운전탱크(220)로 들어간다.The influent is a liquid mixed with contaminants and comes out of the influent storage tank 216 to meet the microbubble mixed liquid. The microbubble mixed liquid mixed with the inflow water enters the operation tank 220.

혼합액체가 흘러가는 배관의 끝에는 노즐(222)이 설치되며, 노즐(222)은 운전탱크(220) 내부에 위치한다. 일반적으로는 운전탱크(220) 내부에 액체가 차있게 되는데, 노즐(222)은 액체에 잠긴 상태가 되며, 노즐(222)을 통해 분사되는 미세기포 혼합액체는 액체와 기체가 동시에 뿜어져 나오는 형태가 된다.A nozzle 222 is installed at the end of the pipe through which the mixed liquid flows, and the nozzle 222 is located inside the driving tank 220. In general, the liquid is filled in the driving tank 220, the nozzle 222 is submerged in the liquid, the micro-bubble mixed liquid sprayed through the nozzle 222 is a form in which the liquid and gas are sprayed at the same time Becomes

특히 고압의 혼합액체가 노즐(222)을 통해서 빠르게 분사되면서 혼합액체의 압력이 급격하게 낮아지게 되고, 이로 인해 더 많은 기포가 발생하면서 운전탱크(220) 내부의 액체로 퍼진다.In particular, as the high pressure mixed liquid is rapidly injected through the nozzle 222, the pressure of the mixed liquid is drastically lowered, and as a result, more bubbles are generated and spread into the liquid inside the driving tank 220.

미세기포가 포함된 혼합액체는 운전탱크(220) 내부에 머물면서 미세기포와 오염물질을 결합시킨다. 미세기포와 결합된 오염물질은 부력에 의해 위로 떠오르게 되고, 처리수배출구(224)에서 외부로 빠져나간다.The mixed liquid containing the microbubbles stays inside the driving tank 220 to combine the microbubbles with the contaminants. The contaminants combined with the microbubbles are lifted up by buoyancy and exit from the treated water outlet 224 to the outside.

그리고 오염물질이 제거된 액체는 다시 배관을 타고 이동하여 미세기포펌프(202)로 되돌아간다.The liquid from which the contaminants have been removed is moved back through the pipe and returned to the microbubble pump 202.

이와 같이 미세기포가 혼합된 액체는 오염물질을 제거한 후에 다시 돌아오는 순환과정을 거치면서 지속적으로 동작하게 된다.As such, the liquid mixed with microbubbles continues to operate while undergoing a cyclic process of returning after removing the contaminants.

만약 본 발명의 기포발생장치를 오염물질 제거용도가 아닌 오존(O3)이나 기포가 용해된 물을 만드는 용도로 사용하는 경우에는 유입수저장탱크(120)를 통해 깨끗한 물을 투입하고, 미세기포펌프(202)에는 오존이나 산소를 주입하는 방식을 사용한다.If the bubble generating device of the present invention is used to make ozone (O 3 ) or bubbles dissolved water, which is not intended to remove contaminants, clean water is introduced through the inflow water storage tank 120 and the microbubble pump is used. In 202, ozone or oxygen is injected.

미세한 하얀색 기포가 포함된 물을 욕조나 연못에 사용할 경우, 기포로 인한 시각적인 변화와 함께 조명장치를 이용하여 문자나 영상을 연출할 수 있다. 그리고 액체 중에 기포가 포함되어 있을 경우, 전기나 음파가 잘 전파되지 못하는 성질을 이용하여 음파나 전기, 초음파 등의 차폐에도 이용할 수 있을 것이다.When water containing fine white bubbles is used in a bathtub or a pond, a character or an image can be produced by using a lighting device with a visual change caused by bubbles. In addition, when bubbles are included in the liquid, electric or sound waves may not be propagated well and may be used for shielding sound waves, electricity, and ultrasonic waves.

이외에도 반도체공장에서 폐수를 처리하거나 추순수를 만들 때, 식품산업이나 축산업, 양어장 등에서 폐수를 처리할 때에도 본 발명의 기포발생장치를 사용할 수 있을 것이다.In addition, when the wastewater is treated in the semiconductor factory or the autumn water is made, the bubble generator of the present invention may be used when treating the wastewater in the food industry, animal husbandry, fish farm, and the like.

한편, 도 3은 미세기포펌프의 내부 구조를 나타낸 절개사시도이며, 도 4는 미세기포펌프의 내부 구조를 나타낸 단면도이다.On the other hand, Figure 3 is a cutaway perspective view showing the internal structure of the microbubble pump, Figure 4 is a cross-sectional view showing the internal structure of the microbubble pump.

본 발명에서 액체와 기체가 혼합되면서 미세기포가 발생하는 핵심적인 부분은 미세기포펌프(202)이며, 미세기포펌프(202)로 사용될 수 있는 대표적인 펌프는 터빈펌프이다. 도 3과 4에서는 터빈펌프의 구조를 기준으로 하여 설명한다.In the present invention, the essential part in which the microbubbles are generated as the liquid and gas are mixed is the microbubble pump 202, and a representative pump that can be used as the microbubble pump 202 is a turbine pump. 3 and 4 will be described based on the structure of the turbine pump.

미세기포펌프(202)는 케이스(202a)의 내부에 회전하는 임펠러(202b)를 구비하여 회전력에 의해 유체를 가압하여 배출하는 구조를 갖는다. 케이스(202a)의 일측 상단에는 제1유입구(202c)와 제2유입구(202d)가 형성되며, 타측 상단에는 배출구(202e)가 형성된다.The microbubble pump 202 has an impeller 202b that rotates inside the case 202a to pressurize and discharge the fluid by the rotational force. A first inlet 202c and a second inlet 202d are formed at an upper end of the case 202a, and an outlet 202e is formed at the other upper end.

본 발명에서는 제1유입구(202c)를 통해 액체(물 등)가 투입되고, 제2유입구(202d)를 통해 기체(공기, 산소, 오존 등)가 투입되며, 배출구(202e)를 통해 혼합액체가 배출되는 것으로 설명한다.In the present invention, liquid (water, etc.) is introduced through the first inlet 202c, gas (air, oxygen, ozone, etc.) is introduced through the second inlet 202d, and the mixed liquid is discharged through the outlet 202e. Explain that it is discharged.

제1유입구(202c)와 제2유입구(202d)를 통해 투입된 액체와 기체는 임펠러(202b)와 함께 회전하면서 혼합되는데, 기체는 임펠러(202b)의 고속 회전에 의해 발생되는 와류로 인해 잘게 쪼개지면서 더욱 미세한 기포가 되며, 액체와 균일하게 섞인 상태에서 배출구(202e)를 통해 나간다.The liquid and gas introduced through the first inlet 202c and the second inlet 202d are mixed with the impeller 202b while rotating, and the gas is finely divided due to the vortex generated by the high speed rotation of the impeller 202b. It becomes a finer bubble and exits through the outlet 202e while being uniformly mixed with the liquid.

만약 미세기포가 액체와 잘 섞이지 않으면 혼합액체가 밖으로 배출되었을 때, 미세기포가 쉽게 공기중으로 흩어지게 되어서 오염물질과의 결합이 잘 이루어지지 않는다. 본 발명에서는 이와 같이 미세기포가 쉽게 액체로부터 분리되지 않도록 잘게 쪼개면서 액체 중에 섞이도록 하는 것이다.If the microbubbles are not mixed well with the liquid, when the mixed liquid is discharged out, the microbubbles are easily dispersed in the air, so that the microbubbles are not easily combined with the contaminants. In the present invention, the micro-bubbles are mixed in the liquid while being finely divided so that the micro-bubbles are not easily separated from the liquid.

한편, 도 5는 오존수 발생을 위한 구성을 나타낸 개념도이다.On the other hand, Figure 5 is a conceptual diagram showing the configuration for the generation of ozone water.

전술한 바와 같이 본 발명은 오존이 혼합된 물(오존수)를 만드는 데에도 사용할 수 있는데, 이를 위해서는 미세기포펌프(202)의 제2유입구(202d)에 오존을 투입하는 라인을 연결한다.As described above, the present invention can also be used to make ozone-mixed water (ozone water). For this purpose, a line for injecting ozone into the second inlet 202d of the microbubble pump 202 is connected.

오존은 PSA산소발생기(302)에서 발생된 산소(O2)를 오존발생기(304)가 전기충격을 통해 생성하는 방식을 사용한다. 그러나 오존을 발생시키는 방법은 이외에도 여러 가지가 있으며, 다양한 방식으로 생산된 오존을 미세기포펌프(202)에 투입하여 오존수를 생성할 수 있다.Ozone uses a method in which the ozone generator 304 generates oxygen (O 2 ) generated by the PSA oxygen generator 302 through electric shock. However, there are many other methods for generating ozone, and ozone produced in various ways may be introduced into the microbubble pump 202 to generate ozone water.

미세기포펌프(202)의 제1유입구(202c)에는 순수한 물을 투입하고, 제2유입구(202d)를 통해서는 오존을 투입하여 미세기포펌프(202)를 회전시키면 오존과 물이 혼합되면서 균일한 오존수를 생산할 수 있다.Pure water is introduced into the first inlet 202c of the microbubble pump 202, and ozone is introduced through the second inlet 202d to rotate the microbubble pump 202 so that ozone and water are uniformly mixed. Can produce ozone water.

생산된 오존수는 압력탱크(208)를 거쳐서 필요한 설비로 이동한다.The ozone water produced is transferred to the necessary equipment via the pressure tank (208).
