SYSTEMS AND METHODS FOR REMOVING PARTICULATE MATTER FROM EXHAUST GAS STREAMS

摘要

A system for removing particulate matter from an exhaust gas includes a housing having an inlet, an outlet, and a drum region between the inlet and the outlet. A drum is rotatably mounted in the drum region of the housing and is aligned with the inlet and the outlet for intercepting the exhaust gas stream passing through the housing. The drum has a cylindrical shaped screen that allows the exhaust gas stream to pass through the drum while collecting the particulate matter present in the exhaust gas stream. As the screen rotates, a scrapper removes the particulate matter collected on the screen. A spray fixture located inside the drum sprays fluid at the inner surface of the screen to removes any particulate matter remaining on the screen after the outer surface of the screen has been scrapped.

1. A system for removing particulate matter from an exhaust gas stream comprising:
a housing having an inlet, an outlet, and a drum region located between said inlet and said outlet; a drum rotatably mounted in said drum region of said housing and being aligned with said inlet and said outlet for intercepting an exhaust gas stream passing through said housing; said drum having a cylindrical shaped screen that allows said exhaust gas stream to pass through said drum while collecting particulate matter present in said exhaust gas stream on an outer surface of said screen; a motor for rotating said drum as said exhaust gas stream passes through said housing; a scrapper adjacent said screen for removing said particulate matter collected on said screen; a spray fixture located inside said drum and having spray nozzles that face an inner surface of said screen for spraying fluid at the inner surface of said screen for removing said particulate matter remaining on the outer surface of said screen after the outer surface of said screen has been scrapped.
