Description
Technical field
The utility model relates to sampling thief field, particularly a kind of portable iodine sampling thief that gathers radgas and radioiodine.
Background technology
The monitoring of radioactive nuclide in atmosphere is an important method of radioactivity monitoring in environment and nuclear accident situation.In the monitoring of atmospheric radioactivity nucleic, obtain the sample continuously with the meaning of representing, be the prerequisite and basis that obtains accurate data and reliable conclusion.China is for particular place, facility in air radioactive nucleic monitoring in the past, and the monitoring of ambient atmosphere radioaerosol/iodine is carried out less.Need to reach the object of monitoring, just must first to radioaerosol/iodine in ambient atmosphere, sample.Therefore the sampling product of radioactive nuclide in atmosphere is had to the larger market demand.
While measuring radioaerosol, be the absorption of minimizing sorbing material to radioaerosol in air, to get rid of the interference of radioaerosol, in the serviceable life of improving sorbing material, will add ultrafine fiber filter paper at air intake opening, and radioaerosol is trapped on ultrafine fiber to reach measurement object.Because the aerial concentration of radioiodine is very low, be difficult to directly carry out qualitative, quantitative measurement.The function of sampling apparatus is to make the air of certain flow flow through sorbing material, airborne radioiodine concentrated on sorbing material, and the radioiodine activity concentrating on adsorbent by measurement, process converts and obtains the concentration of radioiodine in air.
At present, atmospheric sampling gasoloid and iodine can not be sampled simultaneously, and the volume of sampling thief is large, uses inconvenience.Particularly, under adverse weather condition, filter membrane easily causes the shortcomings such as test result is incorrect, unstable properties because climatic factor occurs to stop up.
Based on above-mentioned, how to design a kind of flexible gasoloid/iodine sampling thief simple to operate, stable and reliable for performance, portable, to be applicable to existing environmental monitoring and radiation protection requirements of one's work, be the problem that this area is needed solution badly.
Utility model content
The purpose of this utility model is to provide a kind of portable iodine sampling thief, solves existing sampling thief volume large, and unstable properties is unsuitable for the outdoor problem such as portably use.
The technical matters that the utility model solves can realize by the following technical solutions:
A portable iodine sampling thief, comprises cabinet, and cabinet is connected with an admission gear and an air-out apparatus, and high efficiency second order vacuum blower and electronic monitoring module are set in cabinet; Described admission gear is bell mouth shape, and hydraucone sets gradually locking device, filter paper, honeycomb aluminum membrane filtration chamber, iodine filter cartridge from outside to inside.
Described locking device is connected with hydraucone by screw thread is dismountable.
Described second order vacuum blower comprises inlet end and outlet side, and described inlet end is connected with described admission gear, and described outlet side is connected with described air-out apparatus.
In described electronic monitoring module, be provided with fan speed controller and flow sensor, described fan speed controller is connected with described second order vacuum blower, and described flow sensor is connected with the outlet side of second order vacuum blower.
Described electronic monitoring module also has LCDs, button pad pasting, the gauge tap that is arranged on cabinet outside.
The utility model is simple in structure, easy to use, and has advantages of as follows:
(1) adopt high rotating speed, Wind Volume, the vacuum blower of high blast replaces general vacuum pump, and blower fan low noise, high-level efficiency, the lightweight portable use of being convenient to;
(2) adopt the glass fiber filter paper of the high collection efficiency of particulate and impregnated carbon iodine filter cartridge.24 hours or gasoloid for more time/iodine sampling and easy to operate, sampling head and filter chamber have higher degree of protection, are applicable to outside atmosphere sampling;
(3) adopt built-in flow sensor, effectively guarantee sample gas measuring accuracy.
