Metro Line 2 car air disinfection and purification upgrade case
Subway car air disinfection and purification upgrade case
Metro Line 2, is the third completed and operated subway line in Guangdong Province, China, Metro Line 2 is S-shaped east-southwest direction, west from the Southern Mountain Chiwan Station, through Futian District, east to Luohu District Lotus Tong Station, its logo color is orange.
After the Spring Festival, Metro will also usher in the peak of return to work passenger flow, passenger flow will rise significantly. Scientific prevention and control is essential. In the face of a significant increase in passenger traffic, Metro will be high standards, strict requirements to further strengthen the killing efforts, according to Metro staff, has been the station public areas and facilities and equipment, train seats, handrails, columns and other comprehensive increase in spraying and disinfection frequency.
Air disinfection purification technology, i.e. EBC sterilization filter technology and plasma disinfection sterilization technology, have also been used in the carrier, both technologies are 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.
Project Background

- Shenzhen is a young people’s hard-working paradise, the population of tens of millions of cities, subway daily average passenger flow of millions of times, how to disinfect and sterilize? How to ensure the health and safety of the public during the special period of epidemic prevention and control is a big problem.
- Especially after the Spring Festival to resume production, security machine conveyor belt every day to transport a large number of passengers luggage, the subway space is small, the air is relatively closed, the flow of people is huge, very prone to cross-infection and transmission.
- 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 corona virus transmission is very strong, do a good job of air killing work is urgent.
- Even if the air conditioning filter soaked disinfection, but the effect is not optimistic, ordinary filter is not the surrounding air environment dynamic killing state, constantly gathering fine particles, more likely to breed bacterial viruses, can not be completely killed, microorganisms in the filter inside will also quickly breed.
solution

According to medical experts, the new coronavirus mainly from droplet transmission, aerosol transmission and contact transmission of the three transmission of the isolation of the start to do a good job of protection measures. Shenzhen Metro Line 2 special use of Invic research and development of EBC disinfection filter technology and plasma disinfection sterilization technology, and achieved very good results.
- EBC sterilization 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 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.
Run the effect

- Shenzhen Metro Line 2 is running vehicle start-up transformation, optional EBC sterilization purification module for batch application before the verification work, while the vehicle software with the whole line upgrade, can monitor the working status of disinfection purifier online.
- EBC disinfection filter technology and plasma disinfection and sterilization technology make the air quality in the car more excellent, greatly reduce the risk of cross-infection of viral bacteria, to provide safe and healthy public transport services for the general public.
- 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

- EBC disinfection filter technology can produce oxidation reaction, antivirus punctures the cell membrane, destroys the activity of bioenzyme in cells, plays an killing role.
- EBC disinfection filter technology can also oxidize formaldehyde, quickly decomposed into carbon dioxide and water, no secondary pollution, no saturation restrictions.
- Plasma sterilization technology in plasma 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.
- 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.
- Plasma disinfection and 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.
- Invic air environment disinfection purifier to meet the rail industry two important indicators, quality is more secure!
