In order to be more clearly understood from the use principle of the biological safe type glove box type isolator of this utility model offer,
Below the leak detection flow process in situ and disinfection process to being carried out using this utility model is illustrated.
1st, original position (original state when as just installing) the leak detection flow process of exhaust-air filter:When first order air draft is filtered
When device 27 needs to be detected, at its upstream aerosol generator should be used (such as at the air inlet 24 of powered air-purifying device 3)
Aerosol (finely ground particles) is sent, after aerosol is stable, in air intake surface (the i.e. exhaust outlet of first order exhaust-air filter 27
17) using photometer or particle counter, (photometer and particle counter can be used for aerosol in gathered air at place
Concentration is calculated), the aerosol concentration from upstream is sampled, then photometer or particle counter are connected to into
First downstream sampling of aerosol mouth 29 of one-level exhaust-air filter 27 carries out downstream sampling of aerosol, and (upstream and downstream may also be employed one
Particle counter);
After sampling terminates, according to the aerosol concentration percentage ratio of upstream and downstream, the filtration of first order exhaust-air filter 27 is calculated
Efficiency, the filtration rank (i.e. the levels of the standard of filter efficiency) nominal with first order exhaust-air filter 27 is contrasted, so as to sentence
Disconnected filter and its installation frame whether there is leakage, if being not reaching to the nominal filtration grade of first order exhaust-air filter 27
Not, then illustrate that filter or installation frame have leakage, conversely, explanation is without leakage.
For this utility model, when second level exhaust-air filter 30 needs to be detected, aerosol generator is connected
The first downstream sampling of aerosol mouth 29 to first order exhaust-air filter 27 is (as the aerosol injection of second level exhaust-air filter
Mouthful), aerosol is then sent, after aerosol is stable, then particle counter is connected to into upstream aerosol thief hatch 31, from
And upstream sampling of aerosol is carried out, after reaching the concentration that the relevant criterion for pre-setting is required, particle counter is connected to down
Faint breath colloidal sol thief hatch 34, is sampled and is moved the filters scan leak detection sampling probe 38, and second level air draft is filtered
Device 30 and its frame installed are scanned leak detection, judge that second level exhaust-air filter 30 and its installation frame whether there is and let out
Leakage.If during scanning sample, detecting doubtful leak source, it is then attached to be fixed sampling at doubtful leak source position, if adopting
The population for collecting continues to increase, then illustrate that filter has leak source.
2nd, the disinfection process of isolator:Before sterilization, biological airtight valve 12 is closed so that the second level air draft is filtered
