본 발명은 기체용해반응장치에 관한 것으로, 더욱 상세하게는 에너지 사용을 최소화하면서도 다양한 크기의 기포를 용해시킬 수 있을 뿐만 아니라 기체를 포화상태까지 용해시킬 수 있는 구조를 갖도록 한 기체용해반응장치에 관한 것이다.The present invention relates to a gas dissolving reaction apparatus, and more particularly, to a gas dissolving reaction apparatus having a structure capable of dissolving bubbles of various sizes while minimizing energy use and dissolving gas to a saturated state. will be.

일반적으로, 폐수처리시설이나 오염된 하천, 호소 등에서 수중의 용존산소 부족을 해결하기 위해서 산기관, 산기판에 따른 폭기, 전면폭기, 표면폭기, 심층폭기, 산소폭기, 순환폭기 등을 실시하고, 미생물의 활동을 유지하여 오수를 처리하 는 다양한 방법이 채용되고 있으며, 이러한 방법 중의 하나가 기체용해장치를 사용하여 오수내에 용존산소량을 증가시키는 것이다.In general, in order to solve the dissolved oxygen deficiency in wastewater treatment facilities, polluted rivers and lakes, aeration, front aeration, surface aeration, deep aeration, oxygen aeration, circulation aeration, etc. Various methods of treating sewage by maintaining the activity of microorganisms have been adopted, and one of these methods is to increase the amount of dissolved oxygen in the sewage using a gas dissolving device.

종래의 기체용해장치는 개략적으로 액체 토출구와 액체 배수구를 구비한 탱크와, 상기 액체 토출구와 연결되어 상기 탱크내로 액체를 펌핑하는 펌프와, 상기 탱크와 연통되게 연결되어 탱크내로 기체를 공급하는 가압기체공급기와, 상기 탱크의 액체 토출구에 장착되어 펌핑되는 액체를 탱크내로 분사하는 노즐로 구성되어 있다.A conventional gas dissolving device is a tank having a liquid discharge port and a liquid drain port, a pump connected to the liquid discharge port to pump liquid into the tank, and a pressurized gas connected to the tank to supply gas into the tank. And a nozzle for injecting the pumped liquid into the tank and attached to the liquid discharge port of the tank.

상기와 같은 구성을 갖는 종래의 기체용해장치는 상기 펌프에 의해 탱크내로 오수를 펌핑하는 동시에 상기 가압기체공급장치에 의해 탱크내로 가압기체가 공급됨으로 탱크내의 압력이 점차 높아지며 탱크내로 공급된 가압기체는 탱크내의 오수와 혼합되고, 이러한 상태에서 오수를 대기중에 감압배출시킴으로써 수중에서 용해된 기체를 미세기포로 만들고, 이 미세기포를 수중에 부유시킴으로써 이 기포의 산소를 수중에 용해시킴으로써 수중의 용존산소량을 높이는 것이다.In the conventional gas dissolving device having the configuration as described above, the pressure in the tank is gradually increased because the pressurized gas is supplied into the tank by the pressurized gas supply device while pumping the sewage into the tank by the pump, and the pressurized gas supplied into the tank is It mixes with the sewage in the tank, and discharges the sewage in the air under such a condition to make the gas dissolved in the water into micro bubbles, and by floating the micro bubbles in the water to dissolve the oxygen of the bubble in water to increase the amount of dissolved oxygen in the water. will be.

그러나, 이러한 종래의 기체용해장치는 단지 가압기체의 가압력에 의해서만 탱크내의 오수와 기체를 혼합하기 때문에 산소의 용해효율이 낮다는 문제점이 있었다.However, such a conventional gas dissolving device has a problem in that oxygen dissolution efficiency is low because only the pressurized gas pressurizes the sewage and the gas in the tank.
