Double-channel high-efficiency industrial flue gas purification device

The invention provides a double-channel high-efficiency industrial flue gas purification device, wherein, a primary purifier, a secondary purifier and a centrifugal fan are sequentially connected with the inner part of a casing; the primary purifier is formed by a plurality of parallel corrugated sheets that keep certain distances with one another; the secondary purifier is formed by a group of carbon fiber filter plates that are arranged in a zigzag line manner; the centrifugal fan is connected with a master exhaust pipe so as to form a first passage; a non-return valve is arranged on an outlet flue of the master exhaust pipe; a corrugated sheet section in the casing is connected with the centrifugal fan through an inner exhaust pipe so as to form a second passage; an oil collecting tank is connected with the side wall of the casing; and an automatic flushing device is arranged above the corrugated sheets and the carbon fiber filter plates.
