Description

기액 혼합촉진 수중폭기장치{Submerged Aerator for gas and liquid mixing acceleration}Submerged Aerator for gas and liquid mixing acceleration

본 고안은 하수, 오수, 폐수 등의 정화에 사용되는 수중폭기에 관한 것으로 하수, 오수, 폐수 등의 수중에 설치되어 수중에서 공기를 공급하는 폭기통에서 기액혼합체의 회전력과 상승속도로 증가시켜 보다 효율적으로 수중에 산소로 공급하여 오염된 물을 효율적으로 정화할 수 있는 기액 혼합촉진 수중폭기장치에 관한 것이다.The present invention relates to underwater aeration used for the purification of sewage, sewage, wastewater, etc., which is installed in the water of sewage, sewage, wastewater, etc. to increase the rotational force and ascending speed of the gas-liquid mixture in the aeration tank that supplies air from the The present invention relates to a gas-liquid mixing promotion underwater aeration apparatus capable of efficiently purifying contaminated water by supplying oxygen in water efficiently.

일반적으로 폐수의 정수처리를 위해 개발된 폐수의 정수 처리장치는 대개 협잡물을 걸러주는 스크린조, 부패조, 여과조, 호기성 생물을 배양하는 접촉산화조, 침전조, 소독방류조로 구성되어 있는데, 이러한 구성 중 수중 폭기장치를 사용하여 호기성 생물을 배양하는 접촉산화조의 역할이 상당히 중요하다고 할 수 있다.In general, the wastewater treatment system developed for the treatment of wastewater consists of a screen tank, a filtration tank, a filtration tank, a contact oxidation tank for culturing aerobic organisms, a settling tank, and a disinfection discharge tank. The role of the catalytic oxidizer, which uses aquatic aeration to cultivate aerobic organisms, is of great importance.

즉, 상기한 여러종류의 폐수는 강물을 오염시키는 유기물질이 다량 함유된 상태에서 배출되고 있는 바, 이러한 폐수를 효과적으로 정수처리 하려면 부패된 폐수에 산소를 원활히 공급하여 호기성 미생물의 배양이 신속히 이루어지도록 하여야 하며, 이를 위해 폐수의 정수처리시에는 산소를 원활히 공급하는 수중폭기장치를 주로 사용하고 있다.That is, the various kinds of wastewater are discharged in a state in which a large amount of organic substances contaminating rivers are discharged. In order to effectively purify the wastewater, oxygen is supplied smoothly to the decayed wastewater so that aerobic microorganisms can be cultured quickly. For this, the underwater aeration system that supplies oxygen smoothly is used for the purification of wastewater.

도 1에 도시된 바와 같이, 대한민국실용신안등록 제20-0292647에서는 공기이송관(43)을 통하여 유입된 공기에 의해 오리피스(44)를 통하여 흡수된 물은 와류판(41)을 통과하면서 기액혼합체를 이루고 이 혼합체는 공기혼합돌기(42)에 부딪히면서 더욱 잘게 쪼개져 수중에 산소를 공급하는 수중폭기장치를 제시하였다. 그러나, 이와 같은 수중폭기장치는 돌출된 공기혼합돌기에 의해 기포를 쪼개기 때문에 수중에 섬유상 물질을 포함한 여러 부유물질이 유입되면 공기혼합돌기에 걸려 막힘 현상이 일어나고, 또한 공기혼합돌기에 의해 저항을 받은 유체는 회전속도가 줄어들어 교반능력이 떨어지기 때문에 산소전달 효율이 어느 이상 상승하지 못한 단점이 있었다.또한, 오리피스가 종래 평면으로 형성되어 된 오리피스로 인하여 유입수가 원활하게 유입되지 못하는 단점이 있었다.As shown in FIG. 1, in the Korean Utility Model Registration No. 20-0292647, water absorbed through the orifice 44 by the air introduced through the air transfer pipe 43 passes through the vortex plate 41 to form a gas-liquid mixture. In addition, the mixture was broken into smaller pieces while hitting the air mixing protrusion 42 to propose an underwater aeration apparatus for supplying oxygen in the water. However, the underwater aeration apparatus splits bubbles by protruding air mixing projections, so that when various floating substances including fibrous materials are introduced into the water, they are caught in the air mixing projections and are blocked by the air mixing projections. The fluid has a disadvantage in that the oxygen transfer efficiency does not rise any more because the rotational speed is reduced and the stirring ability is decreased. In addition, the orifice has a disadvantage in that the inflow does not flow smoothly due to the orifice formed in the conventional plane.

도 2 및 도 3에 도시된 바와 같이, 본 고안의 폭기통은 본체(25)의 하부가 후술하는 하부지지체(14)에 고정되고, 본체의 상부는 경사면(27)을 따라 축소되어 본체의 직경보다 축소된 경부를 갖는 토출구(28)가 형성된다. 본체의 내부에는 하부지지체(14)를 통해 유입되는 유입수(2)를 와류시키는 "X"자형의 와류판(26)이 형성되고, 본체 상부의 경사면(27)에는 다수의 공기절단날개(29)가 형성되어 있다.폭기통본체(25)에 결합되는 하부지치체(14)는 내부와 외부가 곡면을 갖는 반원형상으로 형성되고 하부 중앙에 내부가 중공형태의 공기토출구(21)인 결합관(23)이 돌출 형성되고, 내부 곡면을 따라 다수의 오리피스(24)가 배치되어 유입수(2)가 바닥면과 측면으로부터 유입될 수 있도록 한다.As shown in Figures 2 and 3, the aeration container of the present invention is fixed to the lower support 14, which is described below the lower portion of the main body 25, the upper portion of the main body is reduced along the inclined surface 27 to the diameter of the main body A discharge port 28 having a smaller diameter portion is formed. Inside the main body, an “X” shaped vortex 26 is formed to vortex the inflow water 2 flowing through the lower support 14, and a plurality of air cutting blades 29 are provided on the inclined surface 27 of the upper part of the main body. The lower support body 14 coupled to the aeration cylinder body 25 is formed in a semi-circle shape with a curved surface inside and outside, and a coupling pipe having a hollow air outlet 21 inside the hollow at the lower center thereof ( 23 is formed to protrude, and a plurality of orifices 24 are disposed along the inner curved surface to allow the inflow water 2 to flow from the bottom surface and the side surface.

하부지지체의 결합관(23)은 내주벽에 나조가 형성되고 공기이송관의 공기배출부(11)의 외주벽에 형성된 나조(13)에 나사결합되며, 외주벽에는 공기이송관의 공기배출부(11)에 결합될 때에 안정된 구조를 만들기 위하여 4개의 서포트(22)로 지지되는 결합관(23)을 구비한다. 따라서, 이러한 결합에 의해 하부지지체의 공기 토출구(21)는 공기이송관의 공기배출구(11)에 연통하여 공기가 유입된다.따라서, 하부지지체(14)는 반원형상의 중심이 폭기통본체(25)에 결합되기 때문에 구조적으로 안정된다. 또한, 종래에는 유입수가 바닥으로만 유입되었으나 본 고안의 유입수(2)는 바닥면과 측면으로부터 유입되는 장점이 있다.Coupling pipe 23 of the lower support is screwed to the screw thread formed on the outer circumferential wall of the air outlet portion 11 of the air delivery pipe is formed on the inner circumferential wall, the air discharge portion 11 of the air transport pipe on the outer peripheral wall The coupling pipe 23 is supported by the four supports 22 to make a stable structure when coupled to the). Accordingly, the air outlet 21 of the lower support communicates with the air outlet 11 of the air transport pipe by this coupling. Thus, the lower support 14 has a semicircular center in the aeration cylinder body 25. Because they are bonded, they are structurally stable. In addition, conventionally, the inflow water was introduced only to the bottom, but the inflow water 2 of the present invention has an advantage that the inflow from the bottom and the side.

이상과 같이 구성된 본 고안의 작용효과로 상세히 설명하면 다음과 같다.본 고안은 반응조 바닥에 설치된 공기이송관(10)에 공기를 주입하면 공기유체(1)가 공기배출구(11)를 통하여 분출되고, 이 공기의 에어 리프트 효과에 의해 오리피스(24)를 통하여 물이 하부지지체(14)로 흡수되면서 기액혼합유체(3)가 형성되어 폭기통본체(25)로 유입되면서 상승한다. 상승하는 기액혼합유체(3)는 "X"자형 와류판(26)을 통과하면서 기액혼합유체(3)의 상승력의 일부가 회전력으로 바뀌어 회전하면서 상승하는 회전와류형 혼합유체(4)가 발생된다.It will be described in detail as a working effect of the present invention configured as described above. When the air is injected into the air transfer pipe (10) installed on the bottom of the reactor, the air fluid (1) is ejected through the air outlet (11), Due to the air lift effect of the air, the water is absorbed into the lower support 14 through the orifice 24 and as a result, the gas-liquid mixed fluid 3 is formed and rises as it flows into the aeration body 25. As the rising gas-liquid mixed fluid 3 passes through the "X" shaped vortex plate 26, a part of the lifting force of the gas-liquid mixed fluid 3 is changed into a rotational force, and a rotating swirl-type mixed fluid 4 which rises while rotating is generated.

이와 같이 발생된 회전와류형 혼합유체(4)는 토출구(28)를 향해 경사진 경사면(27)을 통과하면서 상승과 회전속도가 증가된다. 이때, 경사면(27)의 내면에 형성된 공기절단날개(29)와 부딪히면서 미세기포로 분해되어 토출구(28)를 통해 미세기포형 혼합유체(5) 상태로 수중에 방출되어 산소공급과 교반의 목적을 달성하게 된다.The rotary swirl-type mixed fluid 4 generated as described above rises and rotates while passing through the inclined surface 27 inclined toward the discharge port 28. At this time, while colliding with the air cutting blades 29 formed on the inner surface of the inclined surface 27 is decomposed into fine bubbles and discharged into the water in the state of the micro-bubble mixed fluid (5) through the discharge port 28 to achieve the purpose of oxygen supply and stirring Done.

이와 같이 본 고안은 종래의 수중폭기장치에서 공기혼합돌기를 없애므로 운전 중 유입되는 부유물질에 의한 막힘 현상을 없애고 상승력과 회전력이 증가된 미세기포형 혼합유체를 발생시킴으로써 종래 장치에 비하여 고장원인이 대폭 줄어들며 폭기효율을 증가시킬 있다.As such, the present invention eliminates air mixing protrusions in the conventional underwater aeration apparatus, thereby eliminating clogging caused by suspended substances introduced during operation, and generating a microbubble type mixed fluid with increased lift and rotational forces, thereby causing failure. It can drastically reduce and increase aeration efficiency.

이상 살펴본 바와 같이, 본 고안의 기액 혼합촉진 수중폭기장치는 폭기통에 유입된 기액혼합유체의 상승력과 회전력을 증대시켜 폭기성능을 향상시킬 수 있는 장점이 있다.또한, 폭기통 내부에서 발생된 회전와류형 혼합유체가 공기절단날개에 부딪히면서 미세기포로 분해시킬 수 있으면서도 유입되는 부유물질에 의한 막힘 현상을 방지할 수 있는 장점이 있다.As described above, the gas-liquid mixing promotion underwater aeration apparatus of the present invention has an advantage of improving the aeration performance by increasing the lifting force and the rotational force of the gas-liquid mixture fluid introduced into the aeration tank. While the flow-type mixed fluid hits the air cutting blade, it can be decomposed into microbubbles, but also has the advantage of preventing clogging caused by the introduced suspended matter.
