Abstract
The invention relates to a leakage monitoring method of air exhausting filter which is biologic safety three-stage and four-stage, including : install a particle counting implement in the wind path which is behind each sending wind high efficiency filer in the biologic laboratory to measure the numbers of the particle with special diameter. It can send the monitoring results to the automatic monitoring system to monitor the leakage of the filter. The invention can monitor the effective monitoring of the leakage of the filter in the high dangerous biologic safety laboratory during the running of the laboratory sending wind system.
Description
Technical field
The present invention relates to automatic control system, exactly, is the automatic control system of dirt thing security laboratory.
Technical background
Three grades of bio-safeties, level Four laboratory are the Experimental Establishments that is used for finishing high-risk bio-safety related experiment, and the primary goal of this facility is safety and the environmentAL safety that guarantees the experimenter.The air draft high efficiency particulate air filter is the equipment that is used for getting rid of harmful substance from discharged air, is air unique assurance that contaminated air safety is discharged from the laboratory, is the important component part that dirt thing safety experiment chamber contamination leaks control.Therefore, must guarantee whenever the air draft high efficiency particulate air filter can not leak,, will in time take measures in case leak.
The leakage monitoring method that adopt present high-risk dirt thing security laboratory is before use in the laboratory mounted air draft high efficiency particulate air filter to be done disposable detection, but often the problem that occurs is: after air draft high efficiency particulate air filter in laboratory detects and passes through, through after a while, may go wrong in case just detect again.Leakage problem once more may take place along with use in this illustrative experiment chamber high efficiency particulate air filter, and if use middle filtrator to leak in the laboratory, may produce the major accident of secure context.
Summary of the invention
The invention provides a kind of to the air draft high efficiency particulate air filter in the high-risk biocontainment laboratory in laboratory ventilation system method of carrying out effective leakage monitoring in service.
Method provided by the invention comprises: the particle counting device is installed in the air channel of each air draft high efficiency particulate air filter back, dirt thing security laboratory, population by specified particle diameter in this measurement device air, the leakage of monitor filter, and monitoring result is sent to automatic monitored control system, thereby reach the purpose of the air draft high efficiency particulate air filter being carried out leakage monitoring.
Said dirt thing security laboratory is: by protective barrier and control measures, reach the biology laboratory and the Animal Lab. of dirt thing safety requirements.Biocontainment laboratory is handled the dirt thing extent of injury and the corresponding safeguard procedures classification of object according to it.The breadboard extent of injury of three-grade biological safety is defined as high individual harm, the harm of low colony; The extent of injury of level Four dirt thing security laboratory is defined as high individual harm, the harm of high colony.
Said air draft high efficiency particulate air filter is meant and is installed on the room air draft pipeline, detects according to GB GB 6165 (" high efficiency particle air filter performance test method "), and its efficient is not less than 99.9% air cleaner.
Said particle counting device is to meet GB GB 50243-2002 (" code for acceptance of construction quality of conditioning works ") requirement, population more than or equal to a certain specified particle diameter in the tested air is detected, and can be with the device of testing result teletransmission to automatic monitored control system.
Description of drawings
Accompanying drawing is the principle schematic of the inventive method.The indoor pollution air filters through high efficiency particulate air filter, enters in the wind output channel, detect by the sample lines extracting air by the particle counting device, and the air after will detecting by the feedback tubes rows to wind output channel.Testing result will be sent to automatic monitored control system at any time.
The specific embodiment
Specifically, monitoring method provided by the invention can adopt following method to realize:
Real time on-line monitoring, so-called real time on-line monitoring are meant administrative staff and do not add under the situation of intervention that following the tracks of continuously, in real time of finishing automatically detects, and carries out the monitoring method of respective handling.
Periodic monitoring;
Monitoring before experiment is carried out.
By the air particles number in the air channel behind the monitoring high efficiency particulate air filter, judge the leakage of whether having sent out dirt of this high efficiency particulate air filter.
