    In order to implement the requirements for normalized prevention and control of the new crown pneumonia epidemic, guide all localities to do a good job in the construction of large-scale centralized isolation points, "combined peace and war" isolation places and other comprehensive centralized isolation places and the renovation of scattered isolation hotels


    Setting standards for centralized isolation of medical observation points


    Sterilization and disinfection device for exhaust port

    1.


    Products use a special high-energy ultraviolet light UV irradiation high ozone gas under irradiation of high-energy ultraviolet light, degrade into low molecular weight compounds, such as CO2, H2O and the like


    High-energy UV beam is used to crack the molecular bonds of bacteria in the gas, destroy the nucleic acid (DNA) of bacteria, and then conduct oxidation reaction through ozone to achieve the purpose of purifying and killing bacteria.


    1.


    Due to the existence of unbalanced and unsaturated molecular attraction or chemical bond force on the surface of activated carbon, when the surface of activated carbon is in contact with gas, it can attract gas molecules to concentrate and keep them on the surface of activated carbon.


    Photo-oxygen activated carbon combines photolysis oxidation technology and activated carbon adsorption technology to perform synergistic purification treatment from gasification to gasification.


    2.


    The large-area PTFE sterilizing filter element is adopted, and the quick-loading structure has a filtration accuracy of 0.

    The research shows that the oxidation potential (2.
    8eV) of active radical·OH is 35% higher than the oxidation potential (2.
    07eV) of ozone which is very oxidizing
    .
    · The reaction rate of OH radicals with organics is several orders of magnitude higher
    .
    Moreover, the reaction of OH radicals to oxidized pollutants is non-selective, and can trigger a chain reaction to directly oxidize most of the harmful substances in the polluted air into carbon dioxide and water or minerals
    .
    Its mechanism of action is as follows:

    H2S+ OH→HS+H2O

    HS+O2+O2++O2-→SO3+H2O

    NH3·OH→NH2+H2O

    NH2+O2+O2++O2→→NOX+H2O

    CH2O+ O2++O2→+·OH→H·COOH+H2O

    Product introduction

    Medical vacuum systems are widely used in medical and surgical operations to provide timely and reliable suction power
    .
    In the environment, increasing sensitivity to contamination and protection against infection make filtration a necessity for these systems
    .
    The necessity of vacuum system filtration has become widespread
    .
    Insufficient inlet filtration can damage the vacuum pump, destroy the vacuum, cause contamination and equipment to stop working
    .
    Inlet line contaminants include particles, dust, moisture and other gases
    .
    Outlet emissions can also include particulates, oil and noxious gases
    .
    Professional inlet and exhaust filters can effectively deal with these pollutants
    .

    Professional sterilization filtration has the danger of carrying a large number of germs in the pipeline and outlet of any vacuum system.
    In order to protect the health of patients, medical staff, other service personnel and the general public, countries have proposed to install and maintain bacterial filtration many years ago.
    device
    .
    Not installing or maintaining a sterilizing filter in front of the vacuum pump will not only damage the vacuum pump, but also make the vacuum pump a source of bacterial contamination
    .
    The right temperature and humidity for a vacuum pump is an ideal breeding ground for bacterial growth, which technically puts the vacuum pump itself at risk, leading to vacuum pump replacement
    .
