Abstract

The current disinfection method of vehicles being applied in South Korea has various shortcomings. So, the epidemic has generated continuously at livestock farms. It is very important to develop an effective disinfection system for reduction of the epidemic. And various basic data is required for this development. Therefore, this study was performed to identify the nozzle type and proper discharge pressure of sprayers. The experiment was conducted from January 10, 2012 until February 28, 2012. All the performance measurement experiments were repeated five times. The subjects of experiment were the A, B and C company's products. The sprayed capacity, angle of spray and the covering area ratio were measured for each product. As a result, the sprayed capacity, angle of spray and the covering area ratio were increased as the discharge pressure of the sprayer was increased. In conclusion, the conical shaped of the nozzle is considered more appropriate than V-shaped, and the proper discharge pressure is expected to be at least 20kg/㎠.

본 연구는 현재 우리나라에서 이뤄지고 있는 차량소독방법의 미흡한 점을 개선하여 국내 축산농가에서 지속적으로 발생하고 있는 각종 전염병을 차단할 수 있는 소독시스템을 개발하는데 필요한 노즐형태와 동력분무기의 적정토출압력을 구명하기 위해 실시되었다. 실험은 2012년 1월 10일부터 2012년 2월 28일까지 진행되었고, 모든 성능실험은 5회 반복으로 측정하였으며, 실험대상은 A사, B사, C사의 제품을 사용했다. 각 회사별 제품에 대해 분무량, 분무각, 피복면적비, 노즐별 분무압력을 측정한 결과, 분무량, 분무각, 피복면적비는 분무기 토출압력이 증가함에 따라 증가하였다(p<0.05). 위 결과와 각 제품의 노즐 위치별 분무량, 분무각, 피복면적비를 측정한 결과를 종합해봤을 때, 노즐의 형태는 부채꼴형 노즐 보다 원추형 노즐의 성능이 우수한 것으로 판단되었으며, 피복면적비를 고려했을 때 분무기의 적정토출압력은 20kg/㎠ 정도면 충분할 것으로 판단되었다.
