초록
섬유 염색 산업은 공장 주변의 주민들이 악취로 인하여 고통을 받고 있으며 반드시 해결해야할 대기오염 문제이며, 특히 텐타공정에서 발생하는 백연과 악취를 저감하여야 한다. 섬유 염색 산업의 주된 대기 오염물질은 탄화수소로 이루어진 유연제, 가소제, 발수제등을 사용하는 후처리 공정에서 주로 발생한다. 화학물질이 처리된 섬유를 텐타공정에서 건조하는 동안 섬유에 포함된 오염물질들이 기화하여 대기로 배출된다. 백연은 주로 1 마이크론 미만의 작은 고상 혹은 액상물질로 이루어져 있으며, 텐타공정에서 발생된 오염물질 분자들이, 이들 입자에 붙어서 상당히 먼 거리까지 이동하며 악취를 유발하게 된다. 텐타공정의 악취를 줄이는 가장 효과적인 방법은 이러한 미세한 오일미스트를 제거하는 것이다. 본 연구에서는 700CMM의 Full-scale EFC (Electric Fume Collector) 운전을 통하여, 악취 및 백연이 효과적으로 제거되었으며 많은 양의 오일을 회수 할 수 있었다.
The textile industry is suffered from air pollution problems which must be resolved. In particular, white smoke and odor after the tenter process require abatement. The major air pollution problem in the textile industry occurs during the finishing stages, where various chemicals are used for coating the fabrics. Lubricating oils, plasticizers, and water repellent chemicals are the fabric treatment chemicals. The coated fabrics are cured by heating in tenter facility. In this process, most of air pollutants emitted into the air. White smoke is basically made up of tiny solid or liquid particles of VOCs less than one micron in size. The oil mist can be carried over long distance from their point of origin. The most effective method of removing odor from tenter process is to get rid of tiny oil mist at the emitted gas. For this reason, the full-scale EFC (Electric Fume Collector) of 700 CMM was tested for removing odorous substances emitted from tenter facility. As a result of this study, odor and white smoke can be eliminated effectively and quite large amounts of oil can be recovered.
