Title
(EN) AIR SATURATOR WITH CIRCULATED WATER SPRAYING NOZZLES HAVING SPIRAL OUTLETS
(KO) 나선형 출구의 순환수 분사노즐을 구비한 공기포화장치
Abstract
(EN)
The present invention relates to an air saturator with circulated water spraying nozzles having spiral outlets. The air saturator comprises: a pressurizing tank which receives pressurized air to make saturated water by saturating the pressurized air in the water; a circulated water inlet pipe which make the circulated water flow through the circulated water spraying nozzles into the pressurizing tank; and a saturated water discharging pipe which discharges the saturated water from the pressurized tank. The air saturator is used for a multistage dissolved air flotation (DAF) method whereby pollutants in raw water is drifted up in order to separate solid from liquid. A spraying hole of the circulated water spraying nozzle is formed in the conical shape. At the same time, a plurality of spiral outlets are formed at intervals from one end portion to the other end portion of an outer circumferential side of the conical spraying nozzle. The air saturator has increased efficiency of saturating air and thus can increase the amount of generated microbubbles for drifting pollutants up. COPYRIGHT KIPO 2015

본 발명은 나선형 출구의 순환수 분사노즐을 구비한 공기포화장치에 관한 것으로서, 물속에 압력공기를 포화시켜 포화수로 만들도록 압력공기를 공급받는 가압탱크, 순환수 분사노즐을 통해 상기 가압탱크 내에 순환수를 유입하는 순환수 유입배관, 상기 가압탱크에서 포화수를 유출하는 포화수 유출배관으로 구성되어, 원수 내의 오염물을 부상시킴으로써 고액분리가 이루어지도록 하는 용존가압부상(DAF) 공법에 사용되는 공기포화장치에 있어서, 상기 순환수 분사노즐의 분사구를 원추형으로 형성됨과 동시에 상기 원추형 분사구의 바깥둘레 면에는 일단부에서 타단부의 나선형을 따라 출구를 비스듬히 기울인 다수개의 나선형 출구를 일정 간격을 두고 형성한 것이며, 공기포화 효율을 높여 오염물 부상을 위한 미세기포의 발생량을 증가시키는 효과가 있다.
