Title: Innovations of Roy J Pellegrin
Introduction
Roy J Pellegrin is an accomplished inventor based in Wailuku, Hawaii. He holds five patents that showcase his innovative contributions to technology, particularly in the field of air filtration and absorption processes. His work has significant implications for both environmental protection and industrial applications.
Latest Patents
One of Pellegrin's latest patents is an absorber that utilizes a liquid solvent formed into a myriad of bubbles and micro-droplets. This solvent froth effectively targets selected components in an incoming gas stream. The design incorporates spaced apart mesh assemblies within absorber tubes or reaction vessels. By employing screens with rectangular wave cross-sections and optimal operating parameters, the absorber maximizes efficiency through solvent pulsing.
Another notable patent is a method and apparatus for simultaneously generating an aqueous froth and numerous micro-droplets for filtering contaminated air streams. This invention enhances the efficiency of an aqueous froth filter by using an array of saturated mesh assemblies that interact with incoming contaminated air. As the air flows through these assemblies, an aqueous froth is generated, and the velocity of the air stream causes bubbles to burst into micro-droplets. These micro-droplets work in conjunction with the froth to bind with contaminants, including chemical and biological warfare agents, making this invention crucial for both safety and industrial applications.
