Need to adopt bag to enter bag to the Exhaust Gas in above-mentioned working range and go out air draft filter element, be convenient to high efficiency particulate air filter to be placed in this unit, the hold-down mechanism of engagement unit and bag device, make attendant under isolation, pack sealing and to change new high efficiency particulate air filter contaminated high efficiency particulate air filter.
Summary of the invention
The object of the present invention is to provide a kind of bag to enter bag and go out air draft filter element, so that the replacing high efficiency particulate air filter of safety guarantees personal security and protection of the environment.
For achieving the above object, the present invention is by the following technical solutions:
A kind of bag enters bag and goes out air draft filter element, comprise a main box, main box is provided with differential manometer interface, upstream probe interface, downstream probe interface, in main box, be provided with three-stage filtration part, be respectively primarily efficient filter part, medium air filtration part, high efficiency filter part, this three-stage filtration part is contained in respectively in corresponding cavity, each cavity is respectively furnished with a set of hold down gag and PVC polybag obturator, the cavity of each filtration fraction is provided with access door, and three-stage filtration part is all furnished with differential manometer; Main box two ends are provided with the switching part of taper, and switching part is provided with stifling mouthful.
Preferably, described switching part is equipped with zero-leakage valve by external interface flange, enter bag and go out air draft filter element in order to close whole bag so that the filter that needs are changed of safety its carry out ozone or hydrogen peroxide suffocating sterilization.
Preferably, described hold down gag is contained in cavity air-out one side of filter, and hold down gag comprises handle and depression bar, the perpendicular connection of handle and depression bar.Rotating handles drives special depression bar, oppresses gradually filter after utilizing depression bar to rotate, and filter is forced to and box inner structure compresses, and reaches the effect of sealing.
Preferably, the four sides arc transition ditch cover with twice U-shaped groove is installed on described access door internal box panel, on it, cover has PVC polybag obturator.
Preferably, described PVC polybag obturator is the polybag with PVC elastic ring.
Preferably, described main box is full weld structure.
The invention has the beneficial effects as follows: filter element of the present invention is the dust that contains radioactivity harmful substance for filtering the filter of replacing filter that simultaneously can be safe.During especially for the high equipment exhaust of the class of pollution, operator can not be subject to the pollution of harmful substance in the time changing filter.So bag enters bag and goes out filter element (BAG IN BAG OUT FILTER UNIT) changing when filter, can prevent that contamination gas colloidal sol in equipment from can not leak into indoor, and operating personnel need not direct contacted filter, just can carry out filter replacement.This filter element has airtight case construction, changes the attendant of filter by the just replacing filter of energy safety of PVC polybag at access door place.Can be widely used in following environment: the biology laboratory that is applicable to BSL 3 and BSL 4 environment; ; Use the exhaust section of high activity medicament/high sensitization medicament factory building and hospital; The Biochemical Labs such as pathogen, virus, bacterium; Biovaccine workshop; Hospital, Disease Control and Prevention Center, Animal diseases research institute; Nuclear industry, radioactive substance laboratory, in the ventilating system in ventilating system treatment of fuels facility, incineration treatment of garbage factory, toxic chemical laboratory or the workshop that contains radioactive substance.
