Description
Technical Field
The invention relates to an exhaust tail gas disinfection and filtration device of a reinforced biosafety laboratory (BSL-2 class laboratory). The classification belongs to the human living needs department according to the International Patent Classification (IPC), and relates to the A61L class of medical technology.
Background
The enhanced biosafety laboratory (BSL-2 class laboratory) is widely used in medical, scientific and biotechnology. By amplifying genes in the virus body through in vitro simulation of DNA replication process, viruses with low content can be detected. Is an important detection method for detecting virus infectious diseases in clinic, such as AIDS, hepatitis B, highly pathogenic respiratory viruses and the like. During the detection process, aerosol containing virus nucleic acid particles is generated, and key operation steps such as laboratory safety, nucleic acid extraction and the like are all carried out in a biosafety cabinet. The air in the laboratory and the biosafety cabinet is exhausted outdoors through an exhaust system, most of the laboratory at present adopts a mechanical ventilation system, and the system is used for controlling the air supply and exhaust proportion and maintaining the negative pressure requirement of each room so as to ensure the experiment. The air flow in the chamber is directed from the "clean" area to the "contaminated" area. The laboratory air supply system can be provided with primary, medium and high-efficiency tertiary air filtration, and the primary and medium-efficiency filters can play a role in prefiltering. The main method for reducing the emission of air pollution is to add a three-stage filtering membrane at the tail end of the exhaust gas so as to reduce the leakage of laboratory pathogens. Many laboratories do not have high efficiency filtration membranes or do not change filtration membranes for long periods, especially in public places. In particular, the nucleic acid fragments of the virus are too tiny and can penetrate through the high-efficiency filter to be discharged outside under the air pressure of the air compressor of the ventilation system. This can cause the pathogenic microorganisms to be directly discharged into the outdoor environment. In addition, in sand storm weather, the high-efficiency filtering membrane of the ventilation system is blocked, so that the negative pressure gradient of a laboratory is changed, the air flow cannot flow directionally, and polluted gas can flow back into the room, so that the experiment cannot be performed normally. Meanwhile, in order to cope with tiny pathogenic microorganisms, the high-efficiency filtering membrane has to be designed too densely, dust particles in the environment are easier to block the high-efficiency filtering membrane, and although the filtering device is improved and the adsorbent capable of adsorbing virus pathogenic microorganisms is added, the blocking of the filtering membrane caused by the dust particles and the like still cannot be solved. Floating landings in the environment cause infection and transmission around and to the population.
Not only are ventilation and exhaust systems of strong biosafety laboratories (BSL-2 class laboratories), hospital infectious disease wards, biomedical laboratories and production workshops, and various places where people gather and move in a room, but also the same problems are faced.

the end of the ventilation system is additionally provided with the inner closed rotary type exhaust device designed by the invention, so that the exhaust mode of the filtering membrane device system of the ventilation exhaust system for the exhaust gas of the current enhanced biosafety laboratory (BSL-2 class) is replaced. The discharged gas is discharged outdoors after being disinfected and cleaned by the inner closed rotary disinfectant and then is discharged into the air environment, so that the pollution and dispersion of the outdoor environment air caused by the overflow of pathogens are prevented. The danger of pollution to the laboratory environment caused by backflow of waste gas due to the change of laboratory pressure caused by the blockage of the filter membrane by dust particles in the atmosphere is avoided.

The gas discharged from the laboratory is sent into the sterilizing liquid in the box body and then is pushed by wind pressure, and directly enters the sterilizing liquid of the lower 2/3. The gas and the disinfection liquid are subjected to resistance to form vortex backflow, and in the process of vortex backflow, the collision frequency between molecules of the disinfection liquid and microbial pathogens is increased under the influence of the intense vortex swirling motion of the airflow, so that the disinfection and sterilization effect is improved, and the disinfection and sterilization process of the first stage is completed.

The liquid state is stable in normal temperature storage. The pH was 7.2. Detecting the heavy metal content of the disinfectant: the lead, arsenic and mercury contents were 0 mg/kg (zero detection). The disinfectant is a multicomponent disinfectant, has long-term effect by synergistic micro action, is completely decomposed into oxygen and water after the disinfectant acts, and does not generate any disinfection byproducts or other toxic and harmful substances. The health of human body is not endangered, and the environmental pollution is not caused. In the use process, the sterilization is thorough, colorless and odorless, high-efficiency sterilization is realized, the sterilization is rapid and safe without residues, the sterilization performance is stable, the sterilization is not influenced by environment ph, temperature and illumination, microorganisms are thoroughly killed, and spores can be killed within 3-5 minutes. The sterilization effect is rapid, and the time is greatly saved, thereby improving the biological effect of sterilization. Meets the requirements of GMP production environment conditions on aseptic medicine production.
