The air purification and disinfection device blows fresh natural wind for the subway
The construction and opening of the subway marks that the economic and social development of a city has entered a new historical stage , and it also marks that the city's transportation has reached a new level. At the same time that the subway brings convenience and speed to people, the harm caused by a large number of harmful particles contained in the air of the subway and the hidden dangers of the fire in the relatively closed environment of the subway should also attract our attention. .
　　 February 28, 2003, South Korea Daegu subway fire station, 12 cars were burned and 192 people were killed and 148 people were injured, the cause of the accident is so serious casualties, which do not exhaust facilities within the station area Improvement is an important factor. In addition, a large amount of harmful substances such as carbon monoxide generated when the vehicle material is burned are not decomposed and discharged in time, causing many people to die of poisoning.
How to reduce the harmful particles in the subway air, keep the air in the subway car fresh, and give passengers a comfortable ride environment? How to ensure air circulation in the event of a fire safety accident, promptly eliminate toxic fumes, provide fresh air, and avoid secondary damage to passengers? It is not only a link that can not be ignored in the construction of the subway, but also a powerful pusher to enhance the image of the city. To this end, the reporter interviewed Jin Dahai, manager of Shanghai Kangjiu Environmental Protection Technology Co., Ltd., which specializes in the production of sterilization equipment.
Mr. Jin Dahai said that in the crowded underground station, passengers often feel a little stuffy, which is the dust and carbon dioxide in the air. In the subway, smoking fumes, formaldehyde, benzene, ammonia, hydrazine, TVOC, etc., which are volatilized by building decoration materials , are common sources of pollution. At the same time, the central air-conditioning ventilation system of the subway is easy to accumulate dust in the air duct, and the temperature and humidity of the air in the air duct are high, which is very suitable for the growth and reproduction of bacteria. Therefore, the air-conditioning duct itself is also a source of pollution.
"To reduce the concentration of these pollutants, the bacteria, germs and microorganisms in the airflow can be killed by high-voltage static electricity, and the inhalable dust can be collected to achieve air purification and disinfection, and the air in the public area can be cleaned. Sex and safety. At the same time, in the event of a fire or other safety incident, air circulation can be ensured, and toxic substances in the air can be purified to avoid further deterioration of the disaster."
It is understood that Shanghai Kangjiu's NICOLER pipeline sterilization equipment is a product that uses high-pressure ions for air purification and disinfection. It generates a counter-electric effect in the cavity of the NICOLER through a special pulse signal , and generates a large number of NICOLER high-energy ion bodies. Under the action of the negative pressure fan, the bacteria in the air, the metabolites in the human body, the bacteria in the return air, and the fresh air The secondary contaminants containing bacteria and the system itself (the surface chiller, the inner wall of the pipe, the filter, etc., which are breeding and spreading bacteria) are drawn into the cavity, are rapidly decomposed and kill the bacteria, and then the drug-impregnated activated carbon The secondary sterilization filter of the components enables the treated clean air to circulate rapidly and rapidly, increasing the natural fresh air volume and improving the air quality.
In addition, NICOLER pipeline sterilizing equipment adopts the cold stamping process of bullet casing, which is made of pure copper. It can be customized for the installed or newly installed air conditioning system and ventilation purification system. It can adapt to air conditioners with different air volume. . The installation position is in front of the main pipe of the air duct, the branch pipe or the air conditioner, and has little influence on the original air conditioning ventilation system. During use, there is no need to replace the accessories, no special maintenance is required, and the new fan group is started up. At the same time, NICOLER pipeline sterilization equipment also has energy-saving effect, which can reduce the air volume of the fan and reduce the frequency of replacement of filter consumables, thereby reducing the overall operating cost.
Mr. Jin Dahai believes that the application of the air purification and disinfection device in the subway can not only bring a fresh "natural wind" to the subway, but also give passengers a fresh and clean ride environment, reducing the bacteria and microbes in the air. The occurrence of mass public health incidents; on the other hand, it can decompose harmful substances in time, transport fresh air, reduce the secondary damage caused by the disaster to passengers, and provide a strong guarantee for subway safety.
