Abstract

The invention relates to an impregnated activated carbon sampling box for checking the iodine adsorber efficiency in the environment or a nuclear facility air purification system and inspecting whether radioactive gases contained in the air. The structure of the impregnated activated carbon sampling box comprises a housing and impregnated activated carbon adsorbent arranged in the housing. The housing comprises an upper end cover and a lower end cover which can be fastened together. End surfaces of the upper end cover and the lower end cover are provided with a porous air flow screen respectively. The impregnated activated carbon adsorbent is arranged on a space formed by the upper end cover and the lower end cover through combination. The impregnated activated carbon sampling box provided in the invention has advantages, such as small size, less airflow resistance, large ventilation area, high radioactive gas collecting efficiency, etc. Meanwhile, a plurality of the devices can be combined serially and installed in a special sampling device, so the diversification requirement of the nuclear air purification system and environment sampling can be satisfied to achieve the purpose of radioactive gas inspecting and monitoring.

Description

Immesion active carbon sampling box
Technical field
The invention belongs to core air purification field, be specifically related to a kind of Immesion active carbon sampling box that whether contains radgas in iodine adsorber efficiency in environment or nuclear facilities air cleaning system and check air that checks.
Background technology
In order to guarantee military project, nuclear industry, whether the nuclear facilities safe operations such as nuclear power station, research reactor, reprocessing plant and checking factory building have radio active gas contamination, the gaseous state radiomaterials such as prevention radioiodide enter ambient atmosphere and assurance enters factory building staff safety, set up multiple core air purification air supplying and exhausting systems in nuclear facilities factory building.These systems are under the normal operation of nuclear facilities and accident condition, to stop radioaerosol and radioiodine to enter the last barrier of ambient atmosphere, guarantee them in good state and what guarantee personnel region surrounding air is totally to reduce the important step that radiomaterial discharges source item and guarantees personal security.So, how to adopt quickly and easily to obtain radgas sample in environment or air cleaning system monitoring, be the key of problem.
Summary of the invention
The object of the invention is to for the key issue in sampling, provide a kind of structure can combination in any, realization can be adopted to obtain the Immesion active carbon sampling box of representative sample.
Technical scheme of the present invention is as follows: a kind of Immesion active carbon sampling box, comprise housing and be placed in the Immesion active carbon adsorbent in housing, wherein, described housing comprises upper end cover and the bottom end cover that can snap together, the end face of upper and lower end cap is respectively equipped with porous air-flow web plate, and Immesion active carbon adsorbent is placed in the space forming after upper and lower end cap combination.
Further, Immesion active carbon sampling box as above wherein, is lined with respectively the supporting layer of good air permeability in the porous air-flow web plate of upper and lower end cap.
Further, Immesion active carbon sampling box as above, wherein, described housing is ABS plastic material; Upper and lower end cap is combined and is formed a cylindrical space; Physical dimension after upper and lower end cap combination is Φ 55mm × 27mm.
Further, Immesion active carbon sampling box as above, wherein, the carbon layer of described Immesion active carbon adsorbent is 20mm.
Further, Immesion active carbon sampling box as above, wherein, described Immesion active carbon adsorbent is 40-60 object cocoanut active charcoal.
Beneficial effect of the present invention is as follows: in the present invention, Immesion active carbon sampling box volume is little, gas-flow resistance is little, draught area is large, high to radioactivity arresting efficiency, this sampling charcoal box can multiple tandem compounds (two adjacent sampling charcoal boxes connect with O-ring seal in sampling thief) simultaneously, adopt to more convenient and quicker to obtain representational sample in environment or core air cleaning system.

Embodiment
Below in conjunction with accompanying drawing and implementation process, the present invention is described in detail.
As shown in Figure 1, Immesion active carbon adsorbent 3 is placed in to the columniform ABS plastic shell of Φ 55mm × 27mm, shell is divided into upper end cover 4 and 1 two parts of bottom end cover.As shown in Figure 2, the structure of bottom end cover 1 as shown in Figure 3 for the structure of upper end cover 4.The end face of upper end cover 4 and bottom end cover 1 is respectively equipped with porous air-flow web plate 6,7.The supporting layer 5,2 that is lined with respectively good air permeability in the porous air-flow web plate of upper and lower end cap, supporting layer can adopt soft quality filter paper or other poromeric material.In the present embodiment, upper end cover supporting layer 5 is of a size of Φ 53mm, and bottom end cover supporting layer 2 is of a size of Φ 51mm, and supporting layer and end face can limit adsorbent thickness, movement, spill, and can also guarantee effective draught area simultaneously.
Immesion active carbon adsorbent is the 40-60 order cocoanut active charcoal having flooded, and sieves with 75 eye mesh screens, removes tiny carbon granule and powdered carbon.The carbon layer of Immesion active carbon adsorbent is 20mm.Dress charcoal amount is moderate, can guarantee density, is unlikely to again to break through too much supporting layer, general approximately 19.5 ± 0.5g.
After having loaded, clamp upper and lower end cap by bench vice, sealed firmly with sealing cement is bonding; Cambered surface at shell after bonding completing is labelled; Finally with vacuumizing plastic packaging machine, activated charcoal is packaged in polybag.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technology thereof, the present invention is also intended to comprise these changes and modification interior.
