The present invention relates to the technical field of disinfection and sterilization equipment, in particular to an innovative disinfection and sterilization equipment system.
In response to the severe and complex foreign new coronavirus pandemic and the frequent occurrence of viruses of other types abroad, Beijing CDC released the “Technical Guidelines for the Prevention and Control of International Mails and Express Mails During the Epidemic of New Coronary Pneumonia (First Edition)”, under which, when international mails enter the Chinese customs, the new coronavirus detection and monitoring shall be carried out according to the regulations, and comprehensive preventive disinfection shall be conducted on imported mail bags and outer packaging of express items after opening the bags; with regard to international express mails, customs supervision centers, ports, sorting centers and terminal outlets shall use 500 mg/L chlorine-containing disinfectants or other disinfectants that can be employed on surfaces to spray and sanitize all surfaces of outer packaging of each mail piece, and the surfaces shall get covered and wet completely with disinfectants being retained thereon for at least 30 minutes. The same applies to similar scenarios such as highway entrances and exits, entrances and exits of industrial parks, entrances and exits of farms and garbage stations in COVID-19 high-incidence areas.
At present, disinfectants are often utilized in chemical industries and are flammable, which require special handling and control during storage and transport; further disinfectants are highly corrosive and irritating to human eyes, skin, metals and so on; especially chemical disinfectants are consumables that need to be constantly repurchased in time; in addition, even most commonly used disinfectants leave significant residues that will harm and pollute the environment to some extent, and cannot be discharged via ordinary sewage channels. Therefore, it is urgent to propose an innovative disinfection and sterilization equipment system to solve technical problems mentioned above.
In order to address the technical problems mentioned in the background technology, the present invention provides an innovative disinfection and sterilization equipment system.
The present invention has following technical solutions to solve above-mentioned technical problems. An innovative disinfection and sterilization equipment system, comprises a tap water reservoir system, a disinfectant reactor system, a disinfection and safety door spraying system, a sewage recycling system and a sewage treatment system;
The innovative disinfection and sterilization equipment system of the present invention can carry out 360-degree sterilization spray for vehicles passing through the customs, highway entrances and exits, industrial park entrances and exits, farm entrances and exits, or garbage collection station entrances and exits within 3 minutes and with a sterilization rate over 99%; and the present invention achieves better disinfection and sterilization effectiveness because ozone in water has a half-life of 0.5 h and when passing through the disinfection and safety door spraying system, vehicles can be continually disinfected in at least 20 minutes.
Preferably, water treated by the sewage recycling system is required to have a pH value below 7.5.
Preferably, the general sewage purification scheme is designed only for recycled sewage, wherein garbage of large size such as leaves and stones fallen from vehicles is filtered by a filter system, after judgment by a water quality particle sensor, water is returned to the at least one water tank after precipitation for specific time and dusts and foreign matters are precipitated.
Preferably, the high-level sewage purification scheme is designed for recycled filtered sewage, specifically, garbage of large particles such as leaves, stones, etc., washed or fallen from freight vehicles are filtered through a filter system, and after judgment by a water quality particle sensor, precipitate for a specific time duration, after precipitation, ionize water molecules by at least two 4-inch BDD diamond membrane electrode modules or a plurality of small-size BDD diamond membrane electrode modules energized at low voltage (within 36V) and current of each pair of membranes more than 20 A, thus ozone water is generated to treat sewage to achieve sewage purification with a high cleanliness level.
A speed bump (or a speed limit sign) could be arranged in front of the present invention, so that drivers could slow vehicles down before entering into a disinfection area; size and position sensors could be provided to measure basic information of vehicles and goods like sizes of container trucks, based on which volumes of spray could be determined before starting the disinfection and sterilization equipment system of the present invention; inside the disinfection and safety door spraying system are provided disinfection spray nozzles, respectively arranged at four directions, up, down, left and right sides thereof, so as to spray evenly and increase disinfection efficiency; and the ozone water is sprayed in 360 degrees to ensure complete disinfection, and when disinfection is finished and vehicles depart from exits, infrared cameras could be arranged at exits to record disinfected vehicles, time information and so on.
Compared to the prior art, the present invention has following beneficial effects:
Firstly, the present invention can easily kill bacteria and viruses such as Escherichia coli, Staphylococcus aureus, Salmonella typhimurium, and new coronavirus in a short time, and achieves improved disinfection efficiency.
Secondly, instead of adopting chemical disinfectants, the present invention accomplishes disinfection and sterilization merely by means of adding some water which is easier to obtain.
Thirdly, the present invention makes no corrosive or irritating effect and is so environmentally friendly that would not cause harm to human bodies and would not corrode metal surfaces
Fourthly, the system of present invention can be used repeatedly, which is a one-time investment configuration and hardly needs follow-up costs.
Lastly, the present invention achieves remarkable disinfection and sterilization performance with no emission nor pollution, and is provided with a sewage recycling system so that water can be recycled and reused.
