본 발명은 폐수 등을 정수하는 과정에서 산소를 공급하는 수중폭기장치에 관한 것으로, 특히 수중폭기장치의 전장품이 수중에 부상되게하여 전기사고를 예방함은 물론 공기방울을 미세화하여 용존효율을 극대화시킬 수 있도록 한 초미세 공기방울 생성을 위한 수중폭기장치에 관한 것이다. The present invention relates to an underwater aeration apparatus for supplying oxygen in the process of water purification of waste water, in particular, to prevent electrical accidents by making the electrical equipment of the underwater aeration apparatus float in the water, as well as to minimize the air bubbles to maximize the dissolved efficiency. It relates to an underwater aeration device for generating ultra-fine air bubbles.

일반적으로, 수중폭기장치는 산업폐수나 생활하수나 오수(이하 폐수라 함)를 정수처리하는 과정에서 이용되는 산소발생장치로서, 이 수중폭기장치는 폐수중에 포함된 각종 유기물질에 일정량의 산소를 공급하여 호기성 미생물의 배양이 신속히 이루어지게 하는 기능을 수행하게 된다. In general, an underwater aeration system is an oxygen generator used in the water purification process of industrial wastewater, domestic sewage, or sewage (hereinafter referred to as wastewater). The underwater aeration system uses a certain amount of oxygen to various organic substances contained in the wastewater. It is supplied to perform the function of culturing aerobic microorganisms is made quickly.

예컨대, 수중폭기장치는, 대기중의 공기를 강제로 흡인하여 폐수에 공급하여 용존시키는 것으로서, 대기중의 공기를 송풍하는 송풍기와, 상기 송풍기에 의해 송풍되는 공기를 흡인하는 흡인기 및, 상기 흡인기에 의해 회전 작동하면서 공기방울을 형성하는 공기분사기 등으로 구성된다. For example, the underwater aeration apparatus is forcibly sucking air in the air, supplying it to the waste water, and dissolving it. A blower for blowing air in the air, an aspirator for sucking air blown by the blower, and the aspirator. It is composed of an air injector and the like to form air bubbles while rotating.

따라서, 수중폭기장치의 모터에 직결된 임페라의 회전과정에서 발생하는 부압에 의해 대기중의 공기가 흡입되면서 폐수와 배합되고, 이 과정에서 임펠러의 회전력에 의해 공기방울이 발생함으로 인해 산소의 이동 및 혼합 효과를 일으켜 산소의 용존 현상을 가져오는 것이다. Therefore, the air in the atmosphere is sucked in by the negative pressure generated during the rotation of the impeller directly connected to the motor of the underwater aerator, and is mixed with the wastewater, and in this process, the air is generated by the rotational force of the impeller. It produces the effect of oxygen dissolution.

그런데, 수중폭기장치는 공기의 폭기현상(AERATION) 또는 공기와 폐수의 혼 합현상(MIXING)이 단순히 노즐 등과 같은 공기분사기구에 의해 이루어지는 상태이므로, 폐수 등에서 형성되는 공기방울이 큰 형태로 부상하므로, 산소의 용존효율이 경제적이지 못한 문제점이 있었다. However, the underwater aeration device is a state in which the aeration of air (AERATION) or the mixing of air and wastewater (MIXING) is simply made by an air injection mechanism such as a nozzle, so that the air bubbles formed in the waste water, etc. rises in a large form, There was a problem that the dissolved efficiency of oxygen is not economical.

그리고, 수중폭기장치의 공기분사기(노즐 등)에 형성된 분사공에 폐수중에 포함된 각종 이물질이 끼어져 막히게 되는 경우 수중폭기장치의 작동이 불가능해져 폐수정수에 따른 작업이 불능상태에 도달함은 물론 공기분사기의 교체와 같은 후속처리작업이 요구되는 문제점이 있었다. In addition, if various foreign substances contained in the wastewater are stuck in the injection hole formed in the air injector (nozzle, etc.) of the underwater aeration device, the underwater aeration device is impossible to operate. There was a problem that a subsequent treatment such as replacement of the air injector is required.

더욱이, 수중폭기장치의 전장품이 수중에 침적된 상태이므로 전기에 대한 누전 위험 내지는 폐수에 의한 부식문제가 항상 존재할 뿐만 아니라 노즐 등과 같은 회전기구에 의해 폭기현상과 혼합현상이 이루어지므로 용존효율이 저하됨은 물론 작동비용이 증대되는 문제점이 있었다. In addition, since the electrical equipment of the underwater aeration system is deposited in the water, there is always a risk of leakage of electricity or corrosion by waste water, and aeration and mixing are caused by rotating mechanisms such as nozzles. Of course, there was a problem that the operating cost is increased.

이에, 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 전장품이 수중에 부상되게 하여 전기사고를 예방함은 물론 공기방울을 미세화하여 용존효율을 극대화시킬 수 있도록 한 초미세 공기방울 생성을 위한 수중폭기장치를 제공하는 데에 그 목적이 있다. Thus, the present invention was devised to solve the problems as described above, to create an ultra-fine air bubble to maximize the dissolved efficiency by minimizing the air bubbles as well as preventing electrical accidents by causing electrical equipment to float in the water. The purpose is to provide a submersible aeration device for.

At this time, it is also possible to change the installation position of the motor 11 according to the working conditions and the working environment of the water purification plant, and if it is any rotation means operated by the motor 11 is naturally included in the technical category of the present application.

그리고, 침적부(20)는, 본체부(10)의 하단부에 고정되면서 폐수가 유입되는 것으로서, 상기 본체부(10)의 하단부에 고정판(22)을 통해 고정된 상태에서 폐수중에 침적되는 스커트부(23)와, 상기 고정판(22)에 형성되어 폐수가 유입되는 다수개의 유입공(21)으로 이루어진다. And, the immersion part 20, the waste water is introduced while being fixed to the lower end of the main body portion 10, the skirt portion which is deposited in the waste water in a fixed state through the fixing plate 22 to the lower end of the main body portion 10 23 and a plurality of inlet holes 21 formed in the fixed plate 22 into which wastewater is introduced.

이때, 스커트부(23)의 성형과정에서 예컨대, 그 상부측과 하부측에 확관부를 형성함으로써, 유입공(21)을 통한 폐수의 원활한 유입 및 공기방울의 원활한 배출 및 유동작용을 유도함이 바람직하다. At this time, in the forming process of the skirt 23, for example, by forming an expansion pipe in the upper side and the lower side, it is preferable to induce smooth inflow of wastewater through the inlet hole 21 and smooth discharge and flow of air bubbles. Do.

그리고, 송풍부(30)는, 대기중의 산소를 흡인하여 사용장소에 공급하는 것으로서, 폐수의 상부측에 위치하면서 대기중의 공기를 흡인하는 송풍기(34)와, 이 송풍기(34)와 상기 본체부(10)를 연결하는 제1공기관(31)과, 이 제1공기관(31)과 상기 용존부(40)를 연결하는 제2공기관(32) 및, 상기 제1/2공기관(31,32)을 개폐하는 각각의 밸브(33-1,33-2)로 이루어진다. The blower 30 sucks oxygen in the atmosphere and supplies it to a place of use, which is located on the upper side of the wastewater and blows air in the atmosphere, and the blower 34 and the A first air engine 31 connecting the main body 10, a second air engine 32 connecting the first air engine 31 and the dissolved part 40, and the first and second air engines 31, 32 each of the valves 33-1 and 33-2 for opening and closing.

이때, 본체부(10)의 둘레면에 제2공기관(32)을 장착하는 과정에서 슬리브(35)를 사용함이 바람직하지만, 그 밖에도 잠금구나 고리 등과 같은 고정기구 및 방법을 이용할 수도 있음은 당연하다.At this time, it is preferable to use the sleeve 35 in the process of mounting the second air pipe 32 on the circumferential surface of the main body portion 10, but it is natural that a fixing mechanism such as a lock or a ring can be used. .

물론, 본원발명에서는 초미세 공기방울의 형성기구로서 멤브레인디스크(42)에 한정하여 설명하였지만, 공기방울을 최소화하기 위한 작동기구라면 본원의 기술범주에 포함됨은 당연하다. Of course, the present invention has been described as limited to the membrane disk 42 as the formation mechanism of ultra-fine air bubbles, it is natural that the operating mechanism for minimizing air bubbles are included in the technical category of the present application.

이하, 본 발명에 따른 작용을 설명하면 다음과 같다. Hereinafter, the operation according to the present invention will be described.

먼저, 폐수를 정수처리하기 위하여, 폐수중에 침적부(20)가 잠겨질 정도의 높이를 갖도록 수중폭기장치(1)를 설치하면, 침적부(20)에 형성된 유입공(21)을 따라 처리하고자하는 폐수가 유입된다. First, in order to purify the waste water, when the underwater aeration apparatus 1 is installed to have a height that is enough to submerge the sediment 20 in the waste water, to process along the inlet 21 formed in the sediment 20 Wastewater is introduced.

이렇게 하면, 수중폭기장치(1)에 구성된 모터(11) 등과 같은 전장품이 폐수중에 침적하지 않고 부유상태가 되는 것이다. In this way, electrical equipment such as the motor 11 and the like, which are configured in the underwater aeration apparatus 1, become suspended without being deposited in the wastewater.

그런 다음, 수중폭기장치(1)의 작동스위치(미도시)를 작동하면, 모터(11)에 의해 프로펠러(12)가 회전함과 동시에 송풍부(30)에 의해 흡인되는 공기가 본체 부(10)와 용존부(40)로 공급된다. Then, when the operation switch (not shown) of the underwater aeration device 1 is operated, the air sucked by the blower 30 at the same time as the propeller 12 rotates by the motor 11, the main body portion 10 ) And the dissolved part 40 are supplied.

즉, 송풍부(30)의 밸브(33-1)를 개방하면, 송풍기(34)에 의해 공급되는 공기가 프로펠러(12)의 회전과정에서 흡인되어 본체부(10)로 공급된다.That is, when the valve 33-1 of the blower 30 is opened, air supplied by the blower 34 is sucked during the rotation of the propeller 12 and is supplied to the main body 10.

동시에, 송풍부(30)의 밸브(33-2)를 개방하면, 송풍기(34)에 의해 공급되는 공기가 제1공기관(31)과 제2공기관(32)을 경유하여 용존부(40)로 공급된다. At the same time, when the valve 33-2 of the blower 30 is opened, the air supplied by the blower 34 flows into the dissolved portion 40 via the first air pipe 31 and the second air pipe 32. Supplied.

이어서, 송풍부(30)의 제2공기관(32)에 의해 공급되는 공기가 용존부(40)의 지지축(41)으로 공급되므로, 멤브레인디스크(42)에 관로를 경유하여 공극을 통해 배출되면서 초미세 공기방울을 만든다. Subsequently, since the air supplied by the second air pipe 32 of the blower 30 is supplied to the support shaft 41 of the dissolved portion 40, the air is discharged through the air gap through the conduit to the membrane disc 42. Create ultra-fine air bubbles.

즉, 멤브레인디스크(42)에 형성된 공극이 2마이크로 이하로서 초미세 공기방울이 만들어지므로, 예컨대 침적부(20)에 유입되는 폐수와 공기의 접촉면적이 커져 산소의 용존효율이 증대되는 것이다. That is, since the ultrafine air bubbles are made with the voids formed in the membrane disk 42 less than 2 micro, the contact area between the wastewater and the air flowing into the deposition portion 20 is increased, for example, and the oxygen dissolution efficiency is increased.

이상에서 설명한 바와 같이 본 발명에 따른 초미세 공기방울 생성을 위한 수중폭기장치에 의하면, 수중폭기장치에 의해 형성된 초미세 공기방울에 의해 폐수와 공기의 접촉면적이 넓어져 산소의 용존효율이 증대되므로 수중폭기장치의 정수효율이 향상됨은 물론 장치의 구동에 따른 각종 부대비용이 절감될 뿐만 아니라, 수중폭기장치에 구성된 전장품이 폐수중에 부상된 상태이므로 전기에 대한 누전 위험 내지는 부식문제가 자연스럽게 해결되어 장치의 유지 및 보수에 따른 각종 부대비용이 절감되는 효과가 있는 것이다. As described above, according to the underwater aeration apparatus for generating ultra-fine air bubbles according to the present invention, the contact area between the wastewater and the air is increased by the ultra-fine air bubbles formed by the underwater aeration device, so that the oxygen dissolution efficiency is increased. In addition to improving the water purification efficiency of the underwater aeration system, not only the additional costs associated with the operation of the device are reduced, but also the electrical components configured in the underwater aeration system are injured in the wastewater, so the risk of leakage of electricity or corrosion problems is naturally solved. It is effective to reduce the various incidental costs of maintenance and repair.
