Zhuhai College successfully developed a UVC ultraviolet light sterilization device to prevent the vertical transmission of the new coronavirus through the canal

The UV-C VentGuard (UV-C VentGuard) for rooftop ventilation ducts developed by Zhuhai College with funding from the URA has entered the application stage. A total of 5 devices were installed in the Central Market Building and the transit house in Soy Street in March and May, respectively. , Studies have shown that the device can effectively reduce the risk of poisoning through the throat.

Develop a device that can kill 99.9% of the new coronavirus in one second

The epidemic continues, and the virus has the risk of vertical transmission through the pipes of the building. The research and development team of the Department of Civil Engineering of Zhuhai University began research and development in October 2020. It took only 14 weeks to successfully develop a new UVC ultraviolet light sterilization device.

The newly developed UVC ultraviolet light sterilization device is mainly used at the outlet of the vent pipe connected to the feces. This vent pipe used to balance the air pressure may form a turbulent flow due to the wind blowing through the outlet, and the gas may be reversed. Get out of the building and bring the virus out.

If a UVC device is added to the ventilation pipe, the virus can be killed by strong ultraviolet light before the gas is discharged.

There are 6 UV-C ultraviolet lights in the device, which are activated 24 hours a day, and need to be replaced once every 10 months on average.

Tests by the Department of Biology of Baptist University have confirmed that 99.9% of the new coronavirus can be killed within one second. In addition, the Internet of Things is used for control and monitoring. The maintenance work can be analyzed based on big data to adjust the energy of UV light to balance it. The lifetime of each UV light can be replaced at the cheapest price.

Expert: The most difficult department has no literature to refer to

Lin Zhixiong, head of the Department of Civil Engineering of Zhuhai University, stated that given the high infection rate of COVID-19, the mortality rate is also higher than 2%, and the infection can also be transmitted vertically. "That is, there are 100 infected people, two of them don’t. Lucky will die.” He hopes to develop a new system to stop the vertical transmission of the new crown virus from the channel.

He recalled that the most difficult thing is that "Many foreign and local documents have no data to refer to, because no one may have noticed the threat of vertical transmission before." He hoped that the public would be able to learn about the effects and effectiveness of the device.

Lin Zhenyu, associate professor of the Department of Civil Engineering of Zhuhai University, said that because UVC ultraviolet light sterilization is already a recognized technology, "basically this device can kill all bacteria, H5N1, colds and colds, but more detailed data analysis is done. In the process of arranging."

Lin Zhixiong said that the most hard-working department has no literature to refer to.

Both airports and private properties are considering installation

Lin Zhixiong pointed out that the installation cost of a UVC ultraviolet light sterilization device is about HK$30,000, and the installation time is about two to three hours, depending on the ducts of the building.

At present, Hong Kong International Airport and different private properties are considering installation. If the public is interested in the installation, they can also contact Zhuhai College.

Lin Zhenyu said that the UVC ultraviolet light sterilization device can basically kill all bacteria.
