초록
본 연구는 소와 돼지 식육부산물의 위생처리를 위한 볼텍스 튜브를 이용한 오존수 제조 장치를 개발하기 위해 수행되었다. 오존가스발생에 있어서 가장 중요한 인자는 원료공기의 온도이며, 위생처리를위한 오존수 내 오존농도에 크게 영향을 미친다. 이러한 이유 때문에 오존발생기로 유입되는 원료공기의 온도를 낮추기 위해 볼텍스 튜브가 이용되었다. 성능평가의 결과에 의하면, 공기압축기의 배출공기압력 3~5bar, 볼텍스 튜브의 냉기비율 40~80%와 냉각공기의 압력 0.0~0.4bar가 28.2℃의 주변 공기온도 하에서 볼텍스 튜브의 냉각공기의 온도에 교호적으로 작용하는 것으로 나타났으며(p<0.05), 최적조건은 공기압축기의 배출공기 압력 4bar, 볼텍스 튜브의 냉기비율 40%, 냉각공기의 압력 0.3bar이었다. 최적조건과 주변 공기온도 35℃ 하에서 볼텍스 튜브를 이용한 오존수 제조 장치의 성능을 평가한결과에 의하면, 오존수 내 오존농도가 0.43ppm 이상이었다. 따라서 볼텍스 튜브를 이용한 오존수 제조장치의 성능이 우수하여 여름철 악조건 하에서도 이용이 가능한 것으로 판단된다.
Abstract
This study is carried out to develop an ozonated water generator using vortex tube tosanitarily process the meat by-products of beef and pork. The most influential factor whengenerating ozone is the temperature of raw air, which determines the concentration level ofozone in water. This study utilizes vortex tube as a way to control the temperature of the rawair flowing into the generator. The result of performance test shows that the compatibleconditions are: 3~5bar of air pressure exhausted from a compressor; 40~80% of cold air fromvortex tube; 0.0~0.4bar of cold air pressure; and 28.2℃ of ambient temperature(p<0.05). Theoptimal condition is 4bar of air pressure exhausted from a compressor; 40% of cold air fromvortex tube; and 0.3bar of cold air pressure. The device generates over 0.45ppm of ozonatedwater under the optimal condition with 35℃ of ambient temperature. In short, the generatorwith vortex tube has proven for great performance under a very warm summer seasons.
