Outdoor Air Purification Tower

Controlling air pollution, particularly from PM 2.5 particulate matter, is crucial for protecting human health and the environment. These microscopic particles can penetrate deep into the respiratory system, causing serious health issues such as respiratory illnesses, cardiovascular problems, and even premature death. PM 2.5 is a leading cause of poor air quality, especially in densely populated regions of Asia, where industrial emissions, vehicle exhaust, and biomass burning are prevalent. Reducing this pollution is vital to minimizing its harmful health effects and improving air quality. 

To address this pressing issue, this technology has been developed that focuses on air purification through an automatic hybrid air purification tower based on a wet scrubber system. This system can capture particles as small as 0.3 microns, significantly reducing PM2.5 levels in the air. The hybrid power system ensures that it operates with lower electricity consumption compared to traditional scrubbers, making it both energy-efficient and effective. Additionally, this technology uses water instead of packing materials reducing waste generation. By leveraging this technology, urban environments can see a marked improvement in air quality, leading to better health outcomes and a cleaner atmosphere for all. 

The technology owner seeks collaborations in environmental sustainability, urban development, and public health to support scaling, co-development, R&D collaboration and licensing.  

The system draws in polluted air via an exhaust fan, passing it through two layers of high-speed spray nozzles that enhance water surface tension to capture particles as small as 0.3 microns. The purified air is then disinfected using ultraviolet germicidal irradiation (UVGI) technology and released at breathing level, supported by a propeller for airflow control. A hybrid power system reduces electricity usage during daylight, and water is recycled and sterilized through ozone technology and a filtration system, ensuring efficient, sustainable operation.
