Hanyang University's Fourth Industrial Revolution Research Center registered a patent for efficient dust purification of underground tunnels on August 31.

The Hanyang University Industry-University-Research Cooperation Foundation completed the registration of a patent (patent registration number 10-2144020) for underground spaces using quantum energy fields and waterfalls, natural ventilation methods of tunnels, and purification systems. This is the result of a study by Professor Cho Byung-wan, the director of the Fourth Industrial Revolution Research Institute and a professor in the Department of Civil and Environmental Engineering, to solve the fine dust problem in underground tunnel spaces, such as subways, which is one of the causes of fine dust in Korea.
 
Along with the recent increase of subway construction, the number and length of tunnels has increased, causing air inside the tunnels to flow into the outlet without being ventilated properly with the outside and not purified, causing urban fine dust. The air inside such tunnels contain a number of pollutants that are harmful to the human body, such as micro dust, nitrogen oxides (NOx), sulfur oxides (Sox), formaldehyde, and volatile organic compounds (VOCs).
 
In the case of subways, most of the operating sections are made of underground spaces, which by the piston effect causes train wind when the train enters or leaves the underground station. Such train winds are threatening the health of citizens as fine dust enters the platform through cracks in the screen as well as causing noise, resulting in major air pollution in the platform and on the train. 

To purify the air inside the tunnel, a jet-fan is installed inside the tunnel and filters are applied in ventilation facilities to filter pollutants. In general, expensive purification filters are rarely used due to huge operating costs and noise problems caused by huge electricity consumption of fan-type dust collectors. Fine dust collection vehicles and cleaning vehicles are operated as temporary measures if necessary, but the actual purification effect is insignificant.

The patent describes the natural ventilation methods and devices that maximize the flow of the energy field-based Bernoulli fluid, which is identified by the new advanced quantum mechanics by applying advanced scientific technology in the era of the fourth industrial revolution. Furthermore, it also provides technologies for increasing the flow rate of polluted air inside the tunnel using the sectional change through the dust collector and natural ventilation methods and devices for underground space tunnels using plasma and waterfalls that purify the internal air in real time through quantum energy field-based nano plasma light falls or nano hydrogen antioxidant spray falls in the space of the tunnel.
 
Professor Cho said, "We will consult as the world's first scientific system to solve the serious global fine dust problem in subways including developed countries, so that it can be extensively used in the construction of subways, roads and underwater tunnels around the world with the technology of the fourth industrial revolution, so that it can become a breakthrough in Korea’s construction and management of tunnels."
