Active technology to remove the amount of finedust in Seoul Special City

摘要

Among active particulate abatement technologies, the technology for removing large emission sources has been developed to a considerable extent, and various types of dust collectors are used. In comparison, outdoor air quality control, which has already been released, is limited in its kind and its effect is limited. Representative technologies include artificial rainfall, wet cleaning technology using water spraying / sprinklers, and cleaning vehicles using vacuum cleaners. The technology to remove fine dust that has already been discharged outdoors has a limited application condition such as artificial rainfall, a low level of technology development, a wide range of outdoor environment, Mostly. At this point, it is necessary to develop a technique to remove fine dust from the outdoors at low cost / low energy at a time when the high concentration fine dust which continues for several days is defined as a social disaster that threatens the health of the people.The proposed active dust reduction technology is a method of using topography / artifacts in the Seoul metropolitan area for all outdoor air quality control techniques at low cost / low energy. The first is an effective method to remove fine dust at low cost by using many high-rise buildings included in Seoul with wet cleaning technology using outer wall of high-rise buildings. Second, applying wet cleaning technology to the surface of the vehicle and installing it on a motorway can remove fine dust at low cost. For reference, water curtain technology can be applied to automobile roads. The third is a method of removing fine dust at low cost by installing a wet cleaning device capable of high-pressure / high-pressure spraying on the bridge of Han River and using Han River. The fourth is a method of removing fine dust at low cost by arranging several high-pressure / high-dusting fine dust-removing vessels, which are fire-extinguished on the Han River estuary, in the Han River estuary.
