Abstract
The invention belongs to the field of radiation environment protection and provides a stereo sampling cabin for an extra-large flow aerosol sampler. The stereo sampling cabin comprises a sampling cabin body and a square-round reducer pipe. The square-round reducer pipe is installed at the bottom of the sampling cabin body which is a cuboid-shaped frame structure. The cuboid-shaped frame structure and four edges vertical to the bottom surface extend downward to form extension sections. The extension sections are used as supports of the stereo sampling cabin. The top and the periphery of the sampling cabin body are all provided with air inlets. A filter material rack is arranged at the air inlets. The filter material rack and the sampling cabin body are sealed by the use of sealing strips. The stereo sampling cabin provided by the invention has advantages of large filter area and small volume.
Description
Technical field
The invention belongs to radiation environment protection field, relate to a kind of for sampling ultrahigh flow aerosol device
Three-dimensional sampling cabin.
Background technology
In atmospheric aerosol, the concentration of radionuclide is the lowest, for improving monitoring sensitivity, in daily monitoring
In it is generally required to use sampling ultrahigh flow aerosol device to sample, its sampling flow is generally higher than
500m3/h.Normally used flow is 100m with environment monitoring3The big traffic sampling device of about/h is compared,
The sampling flow minimum of super-flow sampler improves about 5 times.In sampling process, filtering material and
The resistance that sample produces increases along with the increase of gas flow rate, causes the load of sampling pump to increase.In order to
Not increasing the load of sampling pump, the filter area of sampling ultrahigh flow aerosol device must increase accordingly, make
The volume becoming sampler samples cabin is excessive.
Summary of the invention
Based on background above technology, the invention provides a kind of standing for sampling ultrahigh flow aerosol device
Sampler body cabin, has that filter area is big, the feature of small volume.
The technical scheme is that
For the three-dimensional sampling cabin of sampling ultrahigh flow aerosol device, including sampling cabin main body and circumference reducing；
Described circumference reducing is arranged on the bottom of sampling cabin main body；It is characterized in that described sampling cabin main body
For cuboid frame structure, it has downwards extension with four seamed edges of plane perpendicular, and this extension is made
Bearing for solid sampling cabin；Top and the surrounding of described sampling cabin main body are air inlet, at air inlet
Filter material frame is installed；Sealing strip is used to seal between described filter material frame and sampling cabin main body.
In order to prevent rainwater from drenching into sampling cabin main body, above-mentioned three-dimensional sampling cabin also includes blast cap；Described blast cap
Be arranged on the top of sampling cabin main body by loose-leaf, blast cap rotates realization with loose-leaf for axle and opens or close.
Above-mentioned blast cap is spliced by two pieces of triangular plates and two pieces of trapezoidal plates.
Described three-dimensional sampling cabin also includes air spring and retaining mechanism；Described air spring is for opening at blast cap
Time fix blast cap；Described retaining mechanism is for fixing blast cap when blast cap closes.
Above-mentioned retaining mechanism is snap close or latch.
Above-mentioned filter material frame is fixed in the main body of sampling cabin by multiple pressing plates.
The invention have the advantage that
The sampling cabin main body of the present invention is cuboid frame structure, has five air inlets, pacifies at air inlet
Dress filter material frame, greatly increases filter area, reduces the volume of nacelle simultaneously.
Accompanying drawing explanation
Fig. 1 is the present invention top view when blast cap is opened；
Fig. 2 is the front view when blast cap closes of the present invention；
Wherein, 1-blast cap；2-loose-leaf；3-air spring；4-sealing strip；5-filter material frame；6-pressing plate；7-latch；
8-sampling cabin main body；9-has an area of reducing.
Detailed description of the invention
The structure such as Fig. 1 in the three-dimensional sampling cabin for sampling ultrahigh flow aerosol device provided by the present invention
Shown in Fig. 2.
Sampling cabin main body 8 is cuboid frame structure, and its top and surrounding are air inlet, at air inlet
Filter material frame 5 is installed；Filter material frame 5 is arranged in sampling cabin main body 8 by pressing plate 6, and with sealing strip 4
Seal.
The top of sampling cabin main body 8 is provided with blast cap 1, to prevent rainwater from drenching into sampling cabin master by loose-leaf 2
In body 8；Blast cap 1 rotates realization with loose-leaf 2 for axle and opens or close.Blast cap 1 and sampling cabin main body 8
On air spring 3 and retaining mechanism (such as snap close, latch etc.) are installed, wherein, air spring 3 is at blast cap
1 when opening for fixing blast cap 1, retaining mechanism is used for when blast cap 1 closes fixing blast cap 1；This enforcement
Example uses latch 7 to be fixed it when blast cap 1 closes；Blast cap 1 is by two pieces of triangular plates and two pieces
Trapezoidal plate is spliced.
The bottom of sampling cabin main body 8 is provided with circumference reducing 9, it is simple to sampling cabin is connected with rear end pipeline.
