Zhengzhou Metro Line 3 full line car air disinfection and
purification upgrade case

Subway car air disinfection and purification upgrade case

Zhengzhou Metro Line 3, is the sixth subway line opened in Zhengzhou City, Henan Province, China, is a northwest to southeast of Zhengzhou City, the backbone of urban rail transit line, the logo color for the world orange.

Outbreak, out of the need for prevention and control, Zhengzhou Metro temporarily closed some station entrances and exits, with the resumption of some enterprises, Zhengzhou Metro passenger flow gradually rebounded, in order to meet passenger travel needs, the subway will be reopened. Zhengzhou Metro in the station vehicle facilities disinfection and ventilation work at the same time, but also strive to minimize the safety problems brought about by the dense number of car personnel, and further do a good job in epidemic prevention services.

Zhengzhou Metro special and Invic (A-share listing, stock code: 002837) cooperation, was established in 2005, is a national high-tech enterprises, mastering the world’s leading refrigeration system core technology, control technology, structural design technology, has a number of patents. To high-quality product quality and service to win the trust of first-class customers at home and abroad.

Project Background

  1. Many enterprises began to resume production and return to work after the Spring Festival increased the number of people, for the subway epidemic prevention and control work has raised new challenges.
  2. The subway is densely populated, especially as a large population of Henan Province, the provincial capital city Zhengzhou subway passenger traffic is huge can be imagined. The new coronavirus is mainly transmitted by droplets, aerosols and contact, and is highly contagious.
  3. Even if the daily for the train ventilation filter to strengthen disinfection cleaning work, daily spraying and disinfection of the filter. However, there is still a large number of people flow of bacterial virus problems, the air inside the car is difficult to ensure safety.
  4. In the ventilation ducts of air conditioning in cars, more viruses, bacteria and molds are grown and hidden, circulating through the air in the vehicle and being inhaled into the human body, especially during the outbreak, it is very easy to cross-infection and transmission.

solution

The new coronavirus is transmitted by droplets, aerosols and contact, and is highly contagion, so air disinfection is the top priority. Zhengzhou Metro special use of Invic research and development of EBC sterilization filter technology and plasma disinfection sterilization technology, and has a very good effect.

  1. 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.
  2. EBC disinfection filter technology can last more than 90 days, using a broad-spectrum high-efficiency killing rate, 60 seconds of rapid action.
  3. 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. At the same time, the air of TVOC, formaldehyde and other decomposition into 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.

Run the effect

Zhengzhou Metro Line 3 after technical review and tender, through the approval of the Qingdao Quartet, the entire line equipped with EBC air sterilization purifier.

  1. EBC disinfection filter technology broke the traditional air conditioning filter technology bottleneck, through the carrier air environment disinfection purification upgrade antivirus, the train car 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 is available in the car crowd activity place, is harmless to human body, 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!
