종래의 폭기장치는 제2도에 나타난 바와 같이 에어블로워(a)를 이용하여 폭기를 하여왔는데 이러한 방법은 폭기조용적(ℓ≒2h)의 크기와 비례관계가 있으므로 장치의 부지면적이 커야 하고 에어부로워(a)의 압력과 폭기조의 높이(h)로 인한 에어부로워 압력의 한계가 있으므로 이용을(대기압 20℃≒243mg/ ℓ)이 작은 문제점이 있었다.Conventional aerators have been aerated using an air blower (a) as shown in FIG. 2. Since this method is proportional to the size of the aeration tank volume (ℓ ≒ 2h), the area of the apparatus should be large and the air portion Since there is a limit of the air blower pressure due to the pressure of the lower (a) and the height (h) of the aeration tank, there is a problem that the use (atmospheric pressure 20 ° C ≒ 24 3 mg / L) is small.

본 고안은 상기 문제점을 해결하기 위하여 안출한 것으로 폭기시 브로워를 이용하는 대신 고압펌프 및 아스피레이터에 폭기 및 폐수순환을 행하므로서 용존산호 이용을 극대화시키고 장치 규모의 소형화를 기하고자 하는 데 그 목적이 있다.The present invention was devised to solve the above problems. Instead of using a blower during aeration, the purpose of the present invention is to maximize the use of dissolved corals and to downsize the device by performing aeration and waste water circulation in a high pressure pump and an aspirator. have.

상기 목적을 달성하기 위하여 본 고안의 아스피레이션 폭기장치는 폭기조, 아스피레이터, 고압순환펌프로 이루어져 있으며 이를 상세히 설명하면 상기 폭기조는 내부 일측에 방류벽이 그리고 반대측에 월류벽이 설치되어 있고, 상기 아스피레이터는 상기 폭기조 상부에 위치하며, 내부 중앙에는 꼬임형 주름관이 위치하고 상부에는 공기 유입구가 형성되고 하부에는 상기 폭기조 상부를 관통하는 유도관이 결합되어 있고, 유도관 하부에는 분사구멍이 형성된 산기관이 부착되어 있고, 상기 고압순환 펌프는 입구측이 상기 폭기조 하부와 연결되고 출구측이 아스피레이터의 꼬임형 주름관과 연결되어 있는 것을 특징으로 한다.In order to achieve the above object, the aspiration aeration device of the present invention consists of an aeration tank, an aspirator, and a high-pressure circulation pump. When this is explained in detail, the aeration tank is provided with a discharge wall on one side and a overflow wall on the opposite side. The aspirator is located in the upper portion of the aeration tank, a twisted corrugated pipe is located in the inner center, an air inlet is formed in the upper portion, and an induction pipe through the upper portion of the aeration tank is coupled to the lower portion, and an injection hole is formed in the lower portion of the induction pipe. The diffuser is attached, the high-pressure circulation pump is characterized in that the inlet side is connected to the lower aeration tank and the outlet side is connected to the twisted corrugated pipe of the aspirator.

본 고안의 구성을 도면에 의거 상세히 설명한다.The configuration of the present invention will be described in detail with reference to the drawings.

본 고안의 구성은 제1도에 나타난 바와 같이 크게 폭기조(1), 아스피레이터(11), 고압순환펌프(21)로 구성된다.The construction of the present invention is composed of the aeration tank 1, the aspirator 11, the high pressure circulation pump 21 as shown in FIG.

폭기조(1)는 고압순환펌프(21) 흡입측에 방류벽(2)을 설치하여 폭기조(1) 내부유체흐름의 급격한 변화를 없애고, 월류벽(3)을 오폐수 유입측과 반대편에 방류벽(2)보다 늦게 오폐수의 순환율을 높이도록 한다.The aeration tank 1 is provided with a discharge wall 2 on the suction side of the high pressure circulation pump 21 to eliminate the sudden change of the fluid flow inside the aeration tank 1, and the overflow wall 3 is disposed on the opposite side to the wastewater inflow side. Increase the circulation rate of wastewater later than 2).

아스피레이터(11)는 본장치의 핵심으로 꼬임형 주름관(12), 공기 유입구(15'), 유도관(16), 산기관(14)으로 구성되어 있고, 본 아스피레이터(11)는 폭기조(1) 상부에 위치하며 유도관(16) 및 산기관(14)은 폭기조 내부에 위치하여 효과적으로 폭기작업을 수행할 수 있게 한다.The aspirator 11 is composed of a twisted corrugated pipe 12, an air inlet 15 ′, an induction pipe 16, and an diffuser 14 as the core of the apparatus. Located above the aeration tank 1, the induction pipe 16 and the diffuser 14 are located inside the aeration tank to effectively perform aeration.

고압순환펌프(21)는 입구측이 상기 폭기조(1) 하부의 오폐수 유입구쪽과 연결되고 출구측이 아스피레이터의 꼬임형 주름관(12)에 연결되어 있어 유입되는 오폐수를 아스피레이터(11)의 노즐을 통하여 폭기조(1)로 공급한다.The high pressure circulation pump 21 is connected to the waste water inlet side of the lower aeration tank 1 and the outlet side is connected to the twisted corrugated pipe 12 of the aspirator. It supplies to the aeration tank 1 through the nozzle of.

이와 같이 구성된 본 고안의 작용효과를 설명하면, 유입구를 통해 들어온 유입수(4)는 고압순환펌프(21)에 의해 아스피레이터의 꼬임형 주름관(12)으로 보내어지고 여기에서 가압오폐수는 꼬임형 주름관(12)에 의해 회전력을 갖게 되어 회전하게 되고, 회전하는 오폐수는 아스피레이터 노즐(13)을 통과하면서 유속이 급격히 빨라지고 이때 공기유입구(15)에서는 마이너스 압력이 작용하여 공기의 아스피레이션 현상이 발생한다. 아스피레이터 노즐(13)을 통과한 물은 공기와 함께 유도관(16)을 따라 산기관(14)에 도달하여 상부로 분사된다.Referring to the operation and effect of the present invention configured as described above, the inflow water (4) coming through the inlet is sent to the twisted corrugated pipe 12 of the aspirator by the high-pressure circulation pump 21, where the pressurized waste water is twisted corrugated pipe (12) has a rotational force and rotates, the rotating waste water passes through the aspirator nozzle 13, the flow velocity is rapidly increased at this time, the negative pressure is applied at the air inlet (15), the aspiration phenomenon of air Occurs. Water passing through the aspirator nozzle 13 reaches the diffuser 14 along the induction pipe 16 along with the air and is sprayed upward.

상부로 분사된 공기는 헨리의 법칙에 의거 수도(H1)차에 의한 압력에 비례하여 용해도가 증가 용존산소량이 증가한다.According to Henry's law, the air injected to the top increases the solubility in proportion to the pressure caused by the water (H 1 ) difference, and the amount of dissolved oxygen increases.

고압순환펌프(21)의 흡입량은 유입수(4)의 유입량에 따라 방류벽(2) 상부에서 조절되고 고압순환펌프(21)압력에 비례하여 용존산소량도 증가하게 되므로 양호한 산호조건을 만든다.The suction amount of the high pressure circulation pump 21 is adjusted in the upper part of the discharge wall 2 according to the inflow amount of the inflow water 4, and the dissolved oxygen amount also increases in proportion to the pressure of the high pressure circulation pump 21, thereby making a good coral condition.

아스피레이터(11)에서 공기가 아스피레이션 되기 위한 조건은 P1〉P2+P3+유도관 내용적의 공기부력 +(P1-P4)이어야 하고 고압순환펌프의 압력은 H2(M) R10+1.25(펌프효율 80% 고려) 이상이 되어야 한다.The condition for air to be aspirated in the aspirator (11) must be P1> P2 + P3 + .The air buoyancy + (P 1 -P 4 ) of the inductor volume is equal to the pressure of the high-pressure circulation pump H 2 (M) R10 + It should be at least 1.25 (considering 80% pump efficiency).

본 장치는 아스피레이터의 원리를 이용한 장치로서 따로 브로워를 설치하지 않으므로 부지면적과 장치비용을 절감할 수 있을 뿐 아니라 고압순환펌프(21)에 의한 가압으로 수중 용존산소를 증대시킴으로 용존산소에 의한 산화조건을 극대화할 수 있는 장치이다.This device is a device using the principle of aspirator, so it does not install a separate blower, which not only reduces the land area and equipment cost but also increases the dissolved oxygen in the water by pressurization by the high pressure circulation pump 21. It is a device that can maximize oxidation conditions.
