ABSTRACT:
A simple, low cost and reliable total particulate (soot, polynuclear aromatic and aliphatic hydrocarbons and ash) control system is disclosed that separates the particulate burning process from the body of a particulate filter and that needs very little compressed air to regenerate. The system can retrofit any existing diesel-powered equipment. The particulate control system includes a stationary ceramic monolith trap that is regenerated by one or more pulses of high-pressure and low-velocity air that move in the opposite direction of the engine exhaust flow through the trap. The particulate control system in a single trap embodiment conducts the engine exhaust to the atmosphere during regeneration periods, and in a dual trap embodiment, conducts the engine exhaust through two traps that are operated alternatively such that while one is filtering the exhaust the other is being regenerated, and vice versa.
