Vacuum Filtration System for Removing Airborne Particulate Pollutants

Abstract

A vacuum filter apparatus is used to induce the influx of polluted air through a replaceable motor driven filter to remove airborne particulate pollutants. The apparatus comprises a frame with an inlet and outlet. The filter is covering the inlet while a vacuum generator is mounted on a hinged lid that covers the outlet. The filter is stretched over a drive roller and wrapped around a passive roller. The driver roller is connected to a motor through a gear box. The vacuum generator includes at least one blower that induces negative pressure inside the frame. A controller is used to control the normal operation of apparatus and alarms a user with the need of filter replacement. A lift assembly provides attachment of the apparatus to any extraneous carrier, thus, achieving substantial cleaning of polluted air right at fire/demolition sources when deployed in air by drones, lifts, etc.

DETAIL DESCRIPTIONS OF THE INVENTION

[0015] All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

[0016] The present invention is a vacuum filtration system for removing air particulate pollutants, especially generated by wildfires, building fires, building demolitions, house fires, etc. The vacuum filtration apparatus of the present invention is used to actively combat airborne particulate saturation through a filtering system that is continually refreshed through a reel and motor mechanism within a frame and interior thereof. Additionally, a negative air pressure may be generated within the frame through a plurality of fan/blower apertures and fan/blower motors thereof that continually generate negative pressure to draw airborne particulate and pollution into the bottom aperture. The filter of the filtering system is rendered parallel and near flush with the bottom surface of the frame, exposed to the bottom aperture to capture particulate and pollution that is drawn into the apparatus. Further, the apparatus of the present invention may be suspended above the sources of airborne particulate pollutants using an extraneous vehicle or structure to provide the effective air filtration. The extraneous vehicle of structure may include, but is not limited to, drone, crane, lift, truck, telescoping mast, actuated but anchored body and structure, any combination thereof, and so on. Further for a pre-planned control burn, an extraneous fastening means is used to suspend the filter apparatus over the area of the controlled burn in a forest. For uncontrolled and large-scale fire events such as wildfires, multiple squadrons of large autonomous drones flying in formations controlled by artificial intelligence or by operators on the ground can be used to suspend multiple filtering systems of present invention into the areas with the most smoke. Thus, the present invention provides effective, active, and efficient filtration to combat air particulate saturation and pollution such as those produced by wild fires, building fires and demolitions, house fires, and other particulate saturation hazards right at the sources.
