Description
Technical Field
The invention relates to the technical field of exhaust gas virus killing, in particular to an exhaust gas virus killing and deodorizing integrated device and a treatment method thereof.
Background
According to the diagnosis and treatment plan for novel coronavirus pneumonia published at 14.3.2022 (trial ninth edition), the transmission routes of the new coronavirus pneumonia include not only direct transmission and contact transmission, but also aerosol transmission. And cases judged to be infected by aerosol transmission through epidemiological investigation and analysis are found on 10 th and 12 th of 2022 at 4 months. In the novel coronavirus wastewater treatment process, associated waste gas is derived from waste gas formed by biological oxidation reduction, mechanical operation, oxygenation and the like, and may contain pathogenic microorganism aerosol, hydrogen sulfide, methane and the like. Therefore, accompanying waste gas generated in the process of treating the medical wastewater can cause virus transmission, is a potential secondary pollution source with extremely high risk level, and has great population exposure risk and secondary health risk. In order to prevent secondary pollution or infection caused by viruses and odor volatilizing from the upper surface of the medical water treatment structure into the atmosphere, it is necessary to kill pathogenic microorganisms in associated waste gas and eliminate odor in waste water and associated waste gas.
At present, waste gas treatment is mainly focused on the field of deodorization, the research on the killing of pathogenic microorganisms of associated waste gas is less, and a marketized device is avoided.
Common microbial aerosols have a particle size of 0.01 to 100. Mu.m, viral particles 0.02 to 0.3. Mu.m, bacteria and fungi etc. in the range of 0.3 to 100. Mu.m, with disease-related microbial aerosols having a diameter of predominantly 0.1 to 20 μm. The aerosol is relatively dispersed in the associated waste gas, is not easy to kill, and can be concentrated to kill after enrichment. Internationally recognized high-efficiency filter materials are widely applied to high-cleanness occasions such as operating rooms, animal laboratories, crystal experiments and aviation. Research shows that the removal rate of the high-efficiency filter material with the grade of H13-H14 to particles with the diameter of more than 0.3 mu m can reach 99.99 percent, and the high-efficiency filter material can be applied to the enrichment of virus aerosol.
The ultraviolet sterilization technology has the advantages of convenience in operation, remarkable sterilization effect, no chemical residue and the like, and multiple studies prove that ultraviolet light with different wave bands has a good inactivation effect on new coronavirus under specific conditions, and the ultraviolet mode is widely applied to killing of various viruses in the air.
The plasma generated under the action of the strong electric field contains a large amount of high-energy charged particles and active particles, and simultaneously generates heat radiation and ultraviolet rays, and the physicochemical factors can effectively destroy bacteria and viruses. Research proves that the technology is an effective means for killing the aerosol of the new crown.
The photocatalyst is excited by light to form a photogenerated carrier (electron-hole pair), and can initiate a free radical chain reaction to generate various active oxygen species, such as OH, O2, singlet oxygen (1O 2), hydrogen peroxide (H2O 2) and the like, so that the composition components of proteins, nucleic acids, saccharides, lipid substances and the like of viruses can be damaged, and the virus inactivation is realized.
Most of the traditional deodorization devices are biological deodorization, wherein odorous substances in gas are dissolved in water and then removed by the action of microorganisms. The method has high requirements on the humidity and the temperature of the living environment of the microorganisms in the deodorization device, has low automation degree and fussy operation, does not have a sterilization effect, and is not suitable for the treatment of associated waste gas containing viruses.
