Bus disinfection system

Abstract

The invention provides a bus disinfection system. The bus disinfection system comprises a bus body; the bus body comprises a pedestrian volume counting system, a disinfectant preparation system and adisinfectant spraying system; the disinfectant preparation system comprises a water purification unit, a Venturi air-entrapping unit and a micro-nano bubble generator; the water purification unit is connected with the inlet end of the Venturi air-entrapping unit through a pipeline; and the outlet end of the Venturi air-entrapping unit is connected with the micro-nano bubble generator. The disinfectant preparation system is a nano-bubble water generation device based on spiral cutting and sawtooth cutting technologies, nano-bubble water contains a large number of active hydroxyl radicals and hydroxyl groups, and the nano-bubble water is used as an environment-friendly sterilization liquid, does not contain chemical additives and is green and environmentally friendly.

Description

technical field [0001] The present invention relates to the technical field of preparation of nano-bubble sterilizing liquid and air disinfection, in particular to a bus disinfection system and its production technology for environment-friendly sterilizing liquid. Background technique [0002] Buses are an important means of transportation for ordinary people to travel. Every day, a large number of passengers get on and off the bus, which inevitably causes public health problems. For example, parts such as rings, handles, chairs, and handrails are places where people use intensively and bacteria breed. [0003] At present, regular manual disinfection is mostly used for bus disinfection. Due to the dispersion of buses in the operation process, it is difficult to coordinate disinfection personnel to disinfect buses in a timely manner, and additional vehicles are required to transport disinfectant to each start and end station. Therefore, the current bus Car disinfection method...

[0003] At present, regular manual disinfection is mostly used for bus disinfection. Due to the dispersion of buses in the operation process, it is difficult to coordinate disinfection personnel to disinfect buses in a timely manner, and additional vehicles are required to transport disinfectant to each start and end station. Therefore, the current bus Car disinfection methods are difficult to provide effective health protection for passengers

[0004] Chinese patent "CN208591353U" discloses an automatic disinfection system for buses, which can realize automatic disinfection of buses. Ozone water is used as a disinfectant, which has potential safety hazards, and the system uses stepping motors, which has a complicated mechanism and high cost

Ozone can inactivate a variety of viruses and the speed is very fast. It can inactivate 90% of virus oocysts in 1 minute; chlorine dioxide needs to act for 1 hour, and it takes 90 minutes for 80ppm chlorine and 80ppm chlorine ammonia to achieve the same effect. However, dissolved ozone is extremely unstable, and it will emit a pungent odor, and it is easy to self-decompose to generate oxygen. The half-life in water is only about 20 minutes. It is difficult to achieve a high concentration in water by conventional dissolution methods; Gaseous ozone is more stable than dissolved ozone, and its half-life under normal conditions is close to 16 hours; under normal circumstances, breathing ozone at a concentration below 0.1PPM can kill harmful bacteria in the air, and will not cause health threats. Efficacy; but once the concentration exceeds 0.1PPM, it will cause great damage to human health, not only cannot play the role of purification and disinfection, but also produce secondary pollution, and even seriously affect the health of the human respiratory system; and ozone bubbles in The water body will quickly float and overflow. Due to the large overflow of ozone bubbles and self-decomposition, the utilization rate of ozone disinfection water is low, which makes it difficult to improve the treatment efficiency of viruses, bacteria and organic pollutants. Ozone water cannot effectively kill viruses.
