Description
Technical field
The utility model relates to a kind of being applicable to and detects and the system of checking air strainer integrality, particularly a kind of on-the-spot online verification system of air strainer of air draft filtering system.
Background technology
Air-supply or xegregating unit air draft, as biological cabinet (Biological Safety Cabinets, BSC), laboratory exhaust hood and bag advance the integrality that cleanliness factor that bag goes out equipment etc. depends on the air strainer that is used to remove pollutant.High efficiency particle air filter is used to remove particulate pollutant usually.
Standardized operating protocol needs these air strainers regularly to be detected guaranteeing not leak.Be typically, such validation test need stop the operation of xegregating unit so that near tested filtrator.By making filtrator, and adopt the scanned filter of scan method to realize validation test through the tested person gasoloid.Because these xegregating units need often operation objectionable impurities, so need carry out necessary harmless treatment usually earlier before the filtrator validation test.
At present existing those skilled in the art adopt a kind of method that the air strainer of air draft filtering system is manually detected.In this manual detection method, the testing staff operates movably by being installed on gloves on the filter box that sampling probe carries out scanning leak detection.Employed gloves are then kept apart the pollutant in casing external environment condition and operation detection personnel and the casing.
Figure 1A～Fig. 1 D has provided the system of the air strainer integrality of an existing autoscan detection air draft filtering system.The critical piece of filters scan system comprises: filtrator air port or casing, in Figure 1A～Fig. 1 D, be expressed as traditional air draft filtering system 100, wherein, contaminated air earlier after the filtrator 130, the wind output channel 120 that are installed on the air draft plenum chamber 110 discharge.Exhaust outlet 140 illustrates on figure equally.Because all these type systematics 100 all comprise an air draft plenum chamber 110, therefore can utilize this space, in air draft plenum chamber 110 the air sampling inlet is installed, that is scanner head/sampling head 150.
This just means that also the testing staff can keep off filtrator 130 and can finish scanning leak detection for this filtrator.Scanner head 150 can be moved along X or Y direction automatically by XY travel mechanism 160 (scanister) control, perhaps along being installed on series of gears tooth bars in the air draft plenum chamber 110 (not shown) that moves.Fig. 1 C further provide a plurality of scanner heads 150 be linked to be one row and be connected on the scan arm 155.Fig. 1 D then is given in scan arm 155 ' and upward has a plurality of scanning holes or bar seam on big sampling cylinder 150 ' of installation.Sampling head 150 and sampling cylinder cylinder 150 ' are used to the whole downstream end face of mounted filtrator is carried out scanning leak detection.Provided simultaneously on the figure optical particle counter (optical particle counter, OPC) and one section exhaust duct 111.
In the existing autoscan leak detection system, the XY gearing is all sealed to be installed in the plenum chamber 110, the scanning mechanism running gear is installed on the squab panel 115 of plenum chamber 110, and only electric signal and sampling pipe pass to casing outer (not showing on the figure) by gastight joint.When needs were hunted leak, ability was powered to the XY travel mechanism and filtrator is carried out scanning leak detection.
One of them potential problems that existing autoscan leak detection system has are, have complicated scanning system in the inside of air draft plenum chamber, have not only increased the size and the expense of member, have also increased the expense of cleaning and maintenance.This is because existing scanning system is exposed among pollutant and the airflow continuously, and in addition, in some cases, thereby the size of equipment can excessively need extra storage space.Thereby this has caused because of the problem that system's too complex produces (shown in the system type among Fig. 1 C, needing many corpuscular counters to finish the gasoloid test), and shown in the system type among Fig. 1 D, desire is located can not realizing of local defect.
