필터가 장착 된 먼지 감소 팬을 포함하여 새로운 유형의 Composite Cyclone Scrubber를 개발하고, 목표 설치 및 유지 보수 비용에 대해서는 기존 도로 오염 저감 시스템 대비 64 %의 투자비 절감 (61 억 원 vs. 170 억 원), 기존 도로 오염 저감 조치 (72.6 억 원) 대비 사회적 비용편익이 43 % 증가, 50.8 억 원)가 예측되고 있다. 장치의 구성은 송풍기 형 나선형 가이드 베인이며, 분사 압력은 미세먼지를 포집한다. 분사 각도 및 접촉 범위가 다양한 노즐, 스프레이 액체 등과 순환 수를 이용한 스프레이이며, 분사 된 물이 Guide Vane과 45도 각도로 충돌로 인해 오염된 가스를 만나기 때문에 41.4 % 더 많은 미세 먼지를 포집한다. 이는 기존의 집진기보다 141 % 증가한 것이다. 포집 액체, 순환 빗물 및 우물 공급원과 관련하여 우리는 특허에서 막대한 양의 에너지와 경제적으로 절약되는 친환경 시스템을 기대한다. 가이드 베인 및 금속 필터는 90 % 이상의 미세 먼지를 줄였으며, 분무 된 물은 베인과 필터를 청소하여 유지 관리 예산을 최소화했다. 개발 된 설계의 예비 평가를 통해 특징적인 물분사로 인하여 유지 보수 예산을 줄일 수 있다.

Four developed patents have applied for a new type of Composite Cyclone Scrubber followed by the previous research (Cho and Kim, 2017), including dust reducing fan with filters. Regarding target installation and maintenance cost, 64% reduction for investment costs (6.2 billion won vs. 17 billion won) compared to existing road pollution reduction system, while social benefit costs increase by 43% compared to existing road pollution reduction measures (72.6 billion won vs. 50.8 billion won). The composition of the device is an air blower type spiral guide vane, and an injection pressure collecting dust efficiency. A nozzle varies Injection angle and contact range, spray liquid species (waterworks, salty water). The proposed patent tests are circulation water Time-by-Time Spray and collected 41.4% more increased micro dust since the sprayed water meets contaminated gas due to the 45° degree colliding, which is 141% increased conventional dust collector. (Ratio of collection over 85%). As regards the source of collection liquid, circulated rainwater and well water, we expect a huge amount of energy and economically saved eco-friendly system in our patent. Finally, the guided vane and metal filter reduced over 90% micro-dust, while sprayed water cleans the vane and filters, resultantly minimizing the maintenance budget. The preliminary evaluations of the developed design make it possible to reduce not only cheaper maintenance budget due to the characteristic water spraying but the cost of water comes from mainly rain and underground.

가설 설정
1) Direct road injection only at night when the concentration of fine dust is getting worse.
1) The proposed system could work on the roadside or in the basement as a vertical type and horizontal type.
2) The proposed system could work in the subway in a horizontal type.
제안 방법
The final goal of this research is development of composite cyclone structure utilizing reserved water in order to reduce micro dust, range from 2.5 nm to 10 nm size.
The preliminary evaluations of the developed design make it possible to reduce not only cheaper maintenance budget due to the characteristic water spraying but the cost of water comes from mainly rain and underground. The calculated results are possible to be designed over 85% reduced micro dust results.
성능/효과
3) Collecting droplet shows the maximum ratio when they meet directly (0 degree), which is 141% larger pressure value than the conventional one in which water flow upper and lower directions only.
후속연구
The calculated results are possible to be designed over 85% reduced micro dust results. However, the optimum nozzle size and spraying angle with pressure are sensitively dependent with angle of attached guided vanes and the number of metal filters, which needs additional experiments.
