Abstract
Disclosed is a counterflow type filter trap system for filtering particulate matters from engine exhaust gases. A controller for receiving and sending information signals, is included. A metal fiber filter for capturing particulate matters included in the engine exhaust gases is provided. A back pressure sensor for sensing pressure difference between the inlet and the outlet of the metal fiber filter, is formed. A compressed air supplying portion is formed for injecting a compressed air in the opposite direction to the flow of the exhaust gases to separate the captured particulate matters from the metal fiber filter. A particulate matters collecting box for collecting the separated particulate matters and a guiding valve for guiding the separated particulate matters are provided. The life of the filter is lengthened and the apparatus has a simple structure. The filtering efficiency of the exhausted fumes is very high.
