FLOW DISTRIBUTOR WITH SCREENS TO OPTIMIZE THE GAS FLOW IN CATALYZERS AND USE

摘要

This invention refers to a flow distributor using screen(s) to be applied in the catalyzers used in combustion internal motors, automotive or not. This purpose of the distributor is to optimize the flow distribution of the fumes that come from the motor when passing through the catalyzer. The screen(s) are duly determined and carefully placed at the entrance of the catalyzer, thereby reducing the pressure gradient, and avoiding the reverse flow or separation of the limiting layer responsible for the flow non-uniformization inside the catalyzer. This flow distributor with screens is cheap to produce, has a low counter pressure and little heat absorption, besides showing excellent results in improving the uniformity coefficient whenever applied in a catalyzer and compared with other devices currently on the market.
