Description
Technical Field
The invention relates to a high-temperature ventilation sterilizing device for public transport means such as airplanes, trains (high-speed rails, common trains and subways), buses and the like.
Background
With the continuous development of human science and technology and the continuous improvement of social infrastructure, public transport means such as airplanes, trains, buses and the like bring indispensable functions for people going out. Statistically, more than 30 hundred million people take airplanes to travel each year since 2013. In addition, as the end of the first quarter of 2019, the number of passengers transported in high-speed rail in China is more than 100 hundred million, and the public transport is a necessary vehicle for people to go out every day. Therefore, the health and comfort of the environment such as an airplane, a train, a bus and the like are very important. However, in recent years, the public health is seriously threatened by frequent outbreaks of infectious diseases such as influenza, SARS, and new coronary pneumonia, and the transmission routes of these infectious diseases include respiratory droplet transmission, contact transmission, and aerosol transmission. The space of the transportation means such as planes, trains, buses and the like is closed and narrow, and the spread of infectious diseases is easily caused.
For example, when the vehicle is bumpy or trembling, the passengers need to touch different surfaces or handrails to maintain balance. Due to the tight space and crowding of the vehicle, the pathogen laden droplets produced by the patient can be readily transmitted to other people in the vicinity. Aerosol transmission refers to the situation that droplets with germs are mixed in the air, and the formed aerosol flows along with the air and is inhaled to cause infection. Viruses released by patients through sneezing, coughing and speaking accumulate in the air at higher and higher concentrations over time. Due to high tightness of transportation vehicles such as airplanes, trains, buses and the like, aerosol in a closed space is suspended in air and is not easy to diffuse, and the aerosol is finally deposited on the surfaces of bulkheads, seats and the like. In order to ensure the health of the air in a vehicle such as an aircraft before re-operation, it is necessary to rapidly sterilize and effectively sterilize such enclosed spaces before each operation.
The viability of a virus in air depends on the environmental conditions, in particular the ambient temperature and relative humidity. Existing studies have shown that respiratory syncytial virus and coronavirus are more likely to survive in cold and dry environments, which is also the reason influenza usually occurs in cold winter months. The low temperature drying environment creates an excellent environment for the growth and spread of influenza, coronavirus, etc., and therefore, controlling environmental parameters within the enclosed space can reduce the risk of virus spread, and in particular, disinfection and sterilization within the enclosed space can be achieved by rapidly increasing the air temperature within the enclosed space within a short time.
During the outbreak of epidemic, the efficient rapid disinfection and sterilization device is urgently needed to rapidly disinfect and efficiently sterilize the airplane, the train, the public bus and other closed spaces before the closed spaces stop and then operate again, so that the life safety of people is ensured. The following challenges are currently faced with rapid disinfection and efficient sterilization techniques for enclosed spaces:
1) High efficiency-how to achieve rapid disinfection and sterilization of air in enclosed spaces;
2) Safety-does not harm the health of passengers, does not produce harmful by-products, and does not adversely affect the operation of important equipment in the cabin;
3) Stability-the hot air in the enclosed space is stable and controlled;
4) Expandability-the same device can be used in spaces of different sizes, and the sterilizing capacity of the ventilation equipment can be adjusted.
