IPC: B03C3/30
Filed: 2019-04-18
Abstract: The present invention is configured such that vibration generated when a vehicle naturally vibrates during driving is used and converted into an elastic means which uses an eco-friendly non-powered spring. Additionally, water or liquid is contained in a fresh water container and shaken such that vertical motion of the elastic means is further amplified by fluctuations and weight of the liquid shaken in the container. In addition, when the present invention is applied to a fixed facility, a rotation power unit and a crank shaft unit are additionally attached to the facility to have the same effect. More specifically, the present invention relates to a method of repeatedly generating friction static electricity and an apparatus of repeatedly removing fine dust, ultrafine dust, and particles of harmful materials. According to an order of electrification, one filter has a surface formed inside and made of a material easy to lose electrons, and the other filter has a surface formed inside and made of a material which is relatively easy to obtain electrons, and the filters are rubbed to each other by means of the vertical motion of the elastic means to obtain a charged body which repeatedly generates friction static electricity. Accordingly, fine dust, ultrafine dust, and particles of harmful materials which search and react to opposite polarity are repeatedly adsorbed onto the charged body. In addition, the dust and particles are fallen by means of a fallen object inducing means, and the fallen particles can be collected in a collecting container, and the particles in a large amount can be discarded.
