Method and apparatus for agglomerating dry dust particles in a gas stream and separation

摘要: Method and apparatus for improving the efficiency of dry dust recovery from moving gases. A constriction is located in a duct carrying ''''dirty'''' gas dust-producing industrial operation, such as, example, blast furnace, to catcher. The may be central orifice plate or similar means which reduces cross-sectional flow area one portion about one-fourth remaining portions duct, thereby accelerates velocity through that duct. location when used with cyclone type catcher must at least five diameters upstream order increase collection preferably ten
