Technique radgas filter is the common process equipment of nuclear engineering, the purification for radgas.Tradition
Technique radgas filter be arranged in canyon either in equipment room when filter reaches prescribed dose value or pressure difference
, it is necessary to which operating personnel go directly to be replaced when excessive, personnel are easily irradiated.And according to the requirement of technique, technique row
The pneumatic filter combination that gas generally requires multigroup different efficiency could meet filtering requirement.Single filter is an equipment,
Dispersed placement, pipeline length, occupied space is larger, and dose monitoring cable is more, is also unfavorable for unified monitoring dosage.
Utility model content
For defect existing in the prior art, the purpose of this utility model is to provide a kind of pneumatic filter, solves single
A filter arrangement disperses the problem of occupied space is big.
The technical solution of the utility model is as follows：
A kind of pneumatic filter, including supporting plate and at least one set of filter element device；Maintenance container is provided with the supporting plate to connect
Mouthful；The filter element device includes at least two filter element cylinders for being separately installed with different efficiency filter cores；The filter filter
Core cylinder is arranged on the maintenance container interface；Air inlet pipe and air outlet pipe are provided with the filter element cylinder；Same group of filter
In core apparatus, the air inlet pipe of filter element cylinder of the air outlet pipe of the filter element cylinder in upstream with being in downstream is in
Between pipeline connect.
Further, above-mentioned pneumatic filter, the filter element cylinder include cylinder, seben component and break off relations to compress
Device；The seben component sets the opening of the cylinder, and the unhook pressing device is arranged at the seben component and institute
Between the filter core for stating inner barrel.
Further, above-mentioned pneumatic filter, the cylinder lower end are provided with sewer pipe.
Further, above-mentioned pneumatic filter, is provided with positioner and dose monitoring device on the supporting plate.
Further, above-mentioned pneumatic filter, is provided with two groups of filter element devices on same supporting plate.
The beneficial effects of the utility model are as follows：
It is determined that filter element device is laid out by supporting plate, avoids multiple filters and arrange that occupied spaces are big, pipe-line cloth
Inconvenience is put, easy to the arrangement and lead of dose monitoring device.Filter provided by the utility model is completely cut off by supporting plate to be radiated
Property canyon, filter core is overhauled in radiology devices room next door, reduce radiation injury, ensure safety.
