Abstract

A hybrid fabric filter system with a tangential inlet was developed to enhance the performance of the conventional fabric filter systems and its performances were evaluated to compare to that of the existing dust collector. The pressure drop increased rapidly with the increased elapsed time and the face velocity in two filtration systems. But, the increasing ratio of a hybrid fabric filter system compared to the existing dust collector was lower. This result was confirmed from the performance such as cleaning interval, residual pressure drop and dust loading rate. The overall collection efficiency of the hybrid fabric filter system was more than 99.6%, 2% improvement compared to that of the existing dust collector. Especially, the fractional collection efficiency at the particle size of around $1\;\mu\textrm{m}$ was about 10% higher than that of the existing dust collector.

접선유입 방식의 하이브리드형 여과집진장치가 기존의 여과시스템의 성능을 향상시키기 위하여 개발되었고, 기존여과포집진장치와 성능을 비교하기 위하여 성능평가가 이루어졌다. 시간의 경과 및 여과속도의 증가에 따라 두가지 집진장치에 있어서 압력손실이 급격하게 증가하였고, 기존 집진장치에 비해 하이브리드형 여과집진장치의 경우 압력손실 증가율이 적은 것으로 나타났다. 이는 탈진가격 및 잔류압력손실, 먼지부하율 등에 대한 성능비교결과를 토대로 알 수 있었다. 총괄집진효율은 하이브리드형 여과집진장치의 경우 99.6% 이상으로 기존의 집진장치에 비해 2% 정도 향상되는 것으로 나타났다. 특히, $1\;\mu\textrm{m}$ 부근의 미세먼지의 부분집진효율이 기존 장치에 비하여 약 10% 정도 높았다.
