Inventor: KIM SEUNG HYUN
IPC: B01D47/06
Filed: 2020-03-19
Abstract: A technical field of the present invention relates to filtering technology for reducing exhaust gas (carbon, nitrogen, etc.) and fine particles generated from a factory and industrial facilities and vehicles using fossil fuels. First, water of a water tank is sent to a filter main body at high hydraulic pressure by a motor. When the size of water particles is reduced by 0.1 millimeter or less to 10 μm through a nozzle installed in the filter main body and the water is sprayed to exhaust gas inside the filter main body, carbon or other harmful particles with the similar size to that of the water particles included in the exhaust gas are combined to be swept. Non-swept soot particles and fine water particles are repetitively combined with the fine water particles sprayed from other nozzles while passing through a main body path, such that the water particles with the increased weight are eventually swept down by gravity. Accordingly, only the water is used, thereby filtering exhaust gas without requiring replacement of paper or fiber filters.
