Modular V-Configuration High-Volume Air Purification System for Skyscraper Rooftops

PROBLEMMetropolitan centers suffer from critical concentrations of airborne particulate matter (PM2.5/PM10) and volatile pollutants, frequently trapped at high densities between dense skyscraper corridors (urban canyon effect). Existing solutions are typically limited to indoor building HVAC filtration or isolated ground-level "smog towers." Ground towers require valuable public land, are architecturally obtrusive, and fail to filter the massive volumes of moving air circulating at higher altitudes. Conversely, traditional horizontal industrial fan boxes deployed on roofs fail to capture multidirectional urban wind currents efficiently, resulting in extreme mechanical strain, high energy consumption, and poor volumetric turnover. SOLUTION / CORE MECHANISMTo overcome these limitations, this disclosure introduces a structural, modular air-cleaning apparatus configured in a geometric "V" shape, specifically optimized for placement on flat, unutilized commercial skyscraper roofs.The system operates as an autonomous environmental lung and is comprised of the following integrated mechanical components:Convergence V-Frame Intake Housing: Two structural walls meeting at an acute angle to form a V-shaped footprint. This geometry serves as an aerodynamic funnel, catching ambient cross-winds from wide angles and compressing the air volume as it forces it down toward the apex of the V.Apex Multi-Stage Filtration Block: Located directly at the narrow junction (apex) of the V-frame. This contains a dense array of low-resistance industrial pre-filters, HEPA elements, or electrostatic precipitators designed to extract soot, carbon, and fine particulate matter.Apex Extraction Super-Fan: A high-velocity, industrial-grade motorized suction and propulsion fan positioned immediately behind the filtration block.Exhaust Propulsion Leg: The opposite internal channel of the V-housing, optimized to direct the pressurized, purified air stream away from the intake zone to prevent immediate re-filtration cycles.
