Case study of upgrading and reformation of air environment disinfection and purification

Bus Group

The Bus Group was founded in 1975 and became a state-owned holding company in 2004. After 45 years of development, the bus group has become a public transportation-based business, with a full license supported by tourism transportation, car rental, long-distance passenger transportation, advertising media, station construction, property management, new energy charging operations, and smart transportation.

Integrated bus industry Group, is an international joint public transport will (UITP) bus Committee of China’s first executive, taxi and car committee about the rotating presidency of the network unit.
Faced with the increase in passenger flow brought about by the resumption of work and production in various industries in the city, Zaqsons Bus Group optimized its public transportation operation services, and focused on both the prevention and control of the epidemic and the resumption of production and production.

Go all out to provide safe and healthy public transportation services to the general public.
For this reason, Zaqsons Bus Group cooperated with Invic (listed on A shares, stock code: 002837) and was established in 2005 as a national high-tech enterprise. Master the world’s leading refrigeration system core technology, control technology, structural design technology, and have a number of patents. Based on leading environmental control and energy-saving technologies, Invic continues to expand related fields to achieve sustainable development; it has won the trust of first-class customers at home and abroad with high-quality product quality and service, and its products are widely used in communications in China and overseas. , IT, electricity, new energy vehicle rail transit train market.

Project Background

With the increase in the return passenger flow in Shenzhen after the holiday and the return to work and school, all bus lines in the city have gradually returned to normal. The 91 Spring Festival transport bus lines passing through airports and stations are key guarantees, 111 commuter buses serving citizens to and from get off work are encrypted, and point-to-point “epidemic prevention and resumption special lines” are opened to serve medical staff, enterprises and institutions…Shenzhen Bus Group is going all out to adjust the bus capacity Arrangements to ensure that citizens travel during the return to Shenzhen to work.

  1.  The bus space is closed and people are concentrated. During the epidemic, virus and bacteria carriers enter the compartment, and cross-infection and spread are extremely easy to occur.
  2. The seat surface, every corner of the car, cushion pillows, car interiors, handles, and hidden dangers of viruses and bacteria caused by various passengers. Moreover, the spread of the new crown virus is extremely strong, leaving passengers in a dangerous and uneasy environment at all times;
  3. In the ventilation ducts of the air conditioner in the car, more viruses, bacteria, and molds breed and hide, and they are inhaled into the human body through the air circulation in the car;
  4. The effect of the return air filter used in the ordinary air conditioner is not optimistic. The ordinary filter continuously accumulates fine particles, which is more likely to breed bacteria and viruses, and cannot be completely killed. Microbes will quickly breed inside the filter element.

solution

According to medical experts’ recommendations, the new coronavirus should start with the isolation of the three transmission routes of droplet transmission, aerosol transmission, and contact transmission. Shenzhen Bus Group specially adopted EBC disinfection and sterilization filter technology and plasma disinfection and sterilization technology developed by Invic, and achieved very good results.

  1. The EBC disinfection and sterilization filter technology can control the release rate and have a strong contact sterilization effect. It contains anti-toxin substances and has the functions of sterilization and aldehyde removal.
  2. The EBC disinfection and sterilization filter technology can last for more than 90 days, adopt a broad-spectrum and high-efficiency killing rate, and act quickly in 60 seconds.
  3. Plasma in plasma disinfection technology can directly break molecular bonds, cracking and gasifying tissues such as proteins in bacteria into harmless gases.
  4. Plasma disinfection and sterilization technology can sterilize and purify the air, so that the fresh air “0” distance. The germicidal rate is as high as 99%, realizing dynamic disinfection, coexistence of man and machine, and disinfection online at any time.

running result

  1. Shenzhen Bus has installed and used vehicle air disinfection and purifiers in batches, and installed air detection modules in some vehicles. You can check the air quality parameters in the vehicle in real time by following the official account.
  2. EBC disinfection and sterilization filter technology and plasma disinfection and sterilization technology make the air quality in the car better, greatly reduce the risk of virus and bacteria cross-infection, and achieve safe and healthy public transportation services for the general public.

Technical details

  1. The EBC disinfection and sterilization filter technology can produce an oxidation reaction, the anti-toxin substance pierces the cell membrane, destroys the activity of the biological enzyme in the cell, and plays a killing effect.
  2. The EBC disinfection and sterilization filter technology can also oxidize formaldehyde and quickly decompose it into carbon dioxide and water, without secondary pollution and saturation restrictions.
  3. Plasma in plasma disinfection technology can directly break molecular bonds, cracking and gasifying tissues such as proteins in bacteria into harmless gases such as H2, CO2, O2, and N2. At the same time, it can decompose harmful gases such as TVOC and formaldehyde in the air into harmless gases such as CO2 and N2.
  4. Plasma disinfection and sterilization technology can sterilize and purify the air, so that the fresh air “0” distance. The germicidal rate is as high as 99%, realizing dynamic disinfection, coexistence of man and machine, and disinfection online at any time.
  5. Plasma disinfection and sterilization technology has a reliable design, and two important tests in the rail transit industry. This product has passed the simulated subway vibration and shock test and complies with the IEC61373: 2010 rail transit equipment shock and vibration requirements. This product has passed the rail transit EN50121 electromagnetic compatibility test requirements.
  6. Invic’s air environment disinfection and purification upgrade plan meets two important indicators of the rail transit industry, and the quality is more guaranteed!
