The invention also comprises a disinfection and sterilization method acting on the disinfection and sterilization device, wherein the disinfection and sterilization device is connected to the outlet end of the vacuum pump waste gas and waste liquid discharge negative pressure pipeline of the central negative pressure suction system of the hospital, and the method comprises the following steps:
(1) the negative pressure pipeline is connected to a gas-liquid separation tank 11, and an ozone ultraviolet lamp 12 in the gas-liquid separation tank is started to generate ozone and ultraviolet rays to preliminarily sterilize gas;
(2) the gas flows into the tank-type ultraviolet disinfection device 21 through a pipeline, so that the gas is subjected to ultraviolet irradiation for a longer time and fully;
(3) the gas flows into the bacteria filtering device 24, and harmful substances, viruses and bacteria in the gas are filtered and isolated by the filter element unit.
The working principle is as follows:
the ultraviolet germicidal lamp belongs to a low-pressure mercury lamp, and the main two luminous spectral lines are: one is 253.7nm wavelength (approximately equal to 254 nm); the other is 185nm wavelength, both of which are ultraviolet light invisible to the naked eye. The 185nm ozone ultraviolet germicidal lamp can ionize oxygen in air into ozone. The ozone has strong oxidation effect, can effectively kill bacteria, and can make up for the defects that the ultraviolet rays only spread along a straight line and have dead angles in disinfection. The 254nm ultraviolet germicidal lamp can kill bacteria by irradiating DNA of microorganisms, and can play a good role in sterilization by destroying bacterial chromosomes at the wavelength of 250nm-260 m.
The top of the gas-liquid separation tank 11 is provided with a 185nm wavelength ozone ultraviolet lamp 12 which is detachably connected. The ozone ultraviolet lamp 12 is disposed in the glass sleeve and inserted into the gas-liquid separation tank 11. The ozone ultraviolet lamp 12 generates ozone and ultraviolet rays simultaneously to primarily sterilize the gas. The subsequent filter unit that is equipped with of this device that kills, can filter the decomposition to the poor ozone of stability, thereby avoid the combustion gas to remain ozone and pollute external whole air. In addition, the top and bottom outer sides of the gas-liquid separation tank 11 are respectively provided with a water inlet 34 and a water outlet 33 for supplying water.
After gas-liquid separation and preliminary sterilization are performed in the gas-liquid separation tank 11, the gas flows into the near-bottom portion of the can-type ultraviolet sterilizer 21 through the air connection pipe 6 provided.

The ultraviolet germicidal lamp 22 is placed inside a glass sleeve and inserted into the can type ultraviolet sterilizing apparatus 21. In operation, the ultraviolet germicidal lamps 22 are switched for use in turn in order to increase the life span of the can type ultraviolet germicidal device 21 and avoid damage due to excessive heating. During the gas flows through the can type ultraviolet ray sterilizing apparatus 21, the ultraviolet ray irradiation is received for a longer time, so that the bacterial virus in the gas is further killed.
The gas is sterilized and disinfected in the tank type ultraviolet disinfection device 21 and flows into the bacteria filtering device 24. In the present embodiment, the bacteria filtering device 24 is provided with two sets of filters, and a filter cartridge unit is provided in the filters. The filter element unit adopts a microporous membrane filter element. The microporous membrane is a membrane separation technology, the filter is a cylindrical structure, the filter shell is made of 304 stainless steel, and a microporous folding filter element is used as a filtering unit, so that particles and bacteria with the particle size of more than 0.1 mu m in liquid and gas can be filtered. After the gas flows into the filter, the filtering of virus, bacteria and impurities is completed, and the aims of purifying the gas and sterilizing are further achieved.
The gas is filtered by the bacteria filter 24 and then discharged to the atmosphere through the exhaust duct 25.
The sterilization device is used for sterilizing and discharging the gas flowing to the negative pressure suction unit system in the negative pressure pipeline at the clinical end of medical treatment, so that the efficiency of the negative pressure suction system in discharging, filtering and sterilizing the gas is improved, and the gas discharged by the negative pressure system is thoroughly purified; and this sterilization device adopts multiple disinfection combination mode, and ozone and ultraviolet ray primary sterilization disinfection in the gas-liquid separation jar, exhaust gas pass through the disinfection of can-type ultraviolet sterilization device secondary sterilization after, and viral bacterium and impurity are filtered to rethread filter core at last for the device reaches higher sterilization filtration level.
