Abstract
An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream. In contrast to wet scrubbers which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy (in the form of electricity). The first use of corona to remove particles from an aerosol was by Hohlfeld in 1824. However, it was not commercialized until almost a century later. In 1907 Dr. Frederick G. Cottrell applied for a patent on a device for charging particles and then collecting them through electrostatic attraction - the first electrostatic precipitator. He was then a professor of chemistry at the University of California, Berkeley Cottrell first applied the device to the collection of sulfuric acid mist and lead oxide fame emitted from various adversely affected by the lead emission acid making and smelting activities. Vineyards in northern California were being At the time of Cottrell's invention, the theoretical basis for operation was not understood. The operational theory was developed later in the 1920s, in Germany Prof Cottrell used proceeds from his invention to fund scientific research through the creation of a foundation called Research Corporation in 1912 to which he assigned the patents. The intent of the organization was to invention brings made by educators (such as Cottrell into the commercial world for the benefit of society at large The operation of Research Corporation is perpetuated by royalties paid by commercial after commercialization occurs.
