Guangzhou Metro Line 5 car air disinfection purification and
upgrading case (pilot)

Subway car air disinfection and purification upgrade case

Guangzhou Metro Line 5 is the 5th subway line completed and operated in Guangzhou, Guangdong Province, is the key construction project in Guangzhou City in 2008, Guangzhou Metro Line 5 starts at Lukou Station, stops at Wen Chong Station, runs through the old city center, Guangzhou city center group and Pearl River New City CBD, its logo color is red.

In the special period of epidemic prevention and control, according to the Guangzhou Metro, increase the frequency of air and surface disinfection is essential, stations to disinfect 4 times a day, key stations to 5 times a day. Security equipment, self-service equipment, escalators, Braille cards, trash cans, seats, public toilets, shops are not let go. After the operation is complete, it is fully disinfected again. In addition, Guangzhou Metro to 5 as a pilot using a new technology, namely EBC sterilization filter technology and plasma disinfection sterilization technology, both technologies from Invic.

Invic (A-share listing, stock code: 002837), founded in 2005, is a national high-tech enterprises. Master the world’s leading refrigeration system core technology, control technology, structural design technology, has a number of patents. Invic company to leading environmental control and energy-saving technology as the fundamental basis for continuous expansion of related areas to achieve sustainable development; To high-quality product quality and service to win the trust of first-class customers at home and abroad, products are widely used in China and overseas communications, IT, electricity, new energy vehicles rail transit train market.

Project Background

  1. Guangzhou metro daily average daily passenger flow of millions of people, how to carry out air disinfection sterilization? How to ensure the health and safety of the public during the special period of epidemic prevention and control is a big problem.
  2. In response to many people’s concerns about the daily transport of large numbers of passengers’ luggage by the security machine conveyor belt, the subway space is small, the air is relatively closed and the flow of people is huge. Cross-infection and transmission are highly susceptible to cross-infection and transmission if carriers of bacteria enter the carrier.
  3. Seat surface, every corner of the car, cushion pillow, car interior, handlebars, all kinds of passengers brought about by the virus, bacteria hidden dangers. And the new crown virus spread extremely strong, so that passengers are always in a dangerous and disturbed environment.
    Re-production, large flow of people, efficient disinfection and sterilization work is urgent.

solution

The new coronavirus should be protected from the isolation of the three transmission channels of droplet transmission, aerosol transmission and contact transmission. Guangzhou Metro to Line 5 part of the train carriages for the pilot selected Invic brand EBC Yingbao pure research and development of EBC disinfection filter technology and plasma disinfection sterilization technology to the air environment in the car disinfection and purification upgrade, and achieved a very good effect.

EBC disinfection filter technology can control the release speed of strong contact sterilization effect, wrapped in anti-virus substances, at the same time with sterilization and dealdehyde.

EBC disinfection filter technology can last more than 90 days, using a broad-spectrum high-efficiency killing rate, 60 seconds of rapid action.

Plasma in plasma disinfection and sterilization technology can directly interrupt the molecular bonds, so that proteins and other tissues in bacteria lysate gas into harmless gases.

Plasma disinfection technology can disinfect sterilization, purify the air, so that fresh air “0” distance. Bacterial killing rate of more than 99%, to achieve dynamic disinfection, human-machine coexistence, disinfection at any time online.

Run the effect

  1. EBC disinfection filter technology broke the traditional air-conditioning filter sterilization is not thorough, need to be replaced frequently technical bottlenecks, through the special formula of antivirus substances, such as the train carriages and other relatively confined space to do “deep cleaning”, improve the air safety in the car.
  2. Plasma disinfection and sterilization technology can disinfect sterilization, purify the air, make the air quality in subway cars more healthy and safe, greatly reduce the risk of cross-infection of viral bacteria, to provide safe and healthy subway transportation services for the general public.
  3. The technology can be used in the car crowd activity place, strong to kill all kinds of viruses, efficient decomposition of formaldehyde, no secondary pollution. It is safe and harmless to human body and has no side effects.

Technical details

  1. EBC disinfection filter technology can produce oxidation reaction, antivirus punctures the cell membrane, destroys the activity of bioenzyme in cells, plays an killing role.
  2. EBC disinfection filter technology can also oxidize formaldehyde, quickly decomposed into carbon dioxide and water, no secondary pollution, no saturation restrictions.
  3. Plasma in plasma disinfection and sterilization technology can directly interrupt the molecular bonds, so that proteins in bacteria and other tissues lysate gasification into H2,CO2,O2,N2 and other harmless gases. At the same time, the air of TVOC, formaldehyde and other harmful gases can be broken down into CO2, N2 and other harmless gases.
  4. Plasma disinfection sterilization technology can disinfect sterilization, purify the air, so that fresh air “0” distance. Bacterial killing rate of more than 99%, to achieve dynamic disinfection, human-machine coexistence, disinfection at any time online.
  5. Plasma disinfection sterilization technology has a reliable design, rail industry two important tests, this product through the simulation of subway vibration shock test, in line with the IEC61373: 2010 rail transport equipment shock vibration requirements, this product through rail DELIVERY EN50121 electromagnetic compatibility test requirements.
  6. Invic air environment disinfection purifier to meet the rail industry two important indicators, quality is more secure!
