Description
Technical field
The present invention relates to a kind of sterilizer, be particularly used for the paper or the one of textile fabrics such as coin, mail, medicated clothing
Plant sterilizer based on high-power electron beam.
Background technology
Day by day tight along with social activity, the exchange of each row practitioner is more frequent, bank note, mail, the medicated clothing etc. of donation
Paper products have also become the carrier of some pathogenic bacterias and biological virus with textile, cause the mutual infection of contactee, drastically influence
The health of people and social safety.
Hygiene department once detected up to 180,000 unexpectedly, the antibacterial carried in average each banknote from the bank note of domestic circulation,
Including Salmonella, escherichia coli, bacillus pyocyaneus, staphylococcus aureus, Bacillus proteus, hepatitis pathogenic bacteria etc.；Switzerland
Research finds, some influenza virus can survive up to 17 days on bank note, after trace hepatitis virus positive blood pollutes bank note,
Can survive 80 days in the environment of 4 DEG C～37 DEG C；Turkey's University Medical College also did investigation, found that savings person infects liver
Scorching probability reaches six times the most unexpectedly beyond general population！The visible pathogenic bacteria carrying banknote prevents and kills to seem the heaviest
Want.
Calendar year 2001 U.S.'s anthrax attacks event is the life starting several weeks by a definite date together from calendar year 2001 JIUYUE on the 18th occurred in the U.S.
The thing attack of terrorism.Within 18th, begin with people from calendar year 2001 JIUYUE and send the office of several news media the mail containing anthrax bacillus
Room and two democratic senators.This event causes five people dead, and 17 people are infected.This also illustrates that offender also may be used
To implement bioterrorism by the thing such as mail, books.Therefore sterilization scanning is carried out for the paper products such as books, mail
Also it is necessary.
Play its function to allow the textiles such as some duds things continue, be conveyed in the staff needed frequently by donations, so
And if former user has some to be carrier of infection, its used duds thing is possible with disease carrying germ.Therefore, right
It is critically important that these substantial amounts of donations medicated clothings carry out sterilizing, because this is related to the healthy of acceptor and life security.
But at present the sterilizing of the paper product such as coin, mail is only limitted to ultraviolet and ozone, and efficiency is low, effect
The poorest, reduce the circulation life-span of coin and the service life of paper product simultaneously；And to textile fabrics such as some donations medicated clothings
Sterilizing the most all use the working method of rinsing, this not only has directly damage to goods, is also easy to cause water resource
Waste and the sewage pollution to environment.
