The device is advantaged b, include: jar body (1), air inlet (2), overflow mouth (3), gas vent (4), deionized water filling opening (5), organic glass window (6) and conductivity gauge head (7). The utility model provides an in the current technique, the UF6 who takes place in the gasification tank leaks the problem of unable externally direct observation and monitoring, use the utility model discloses a device can direct whether the leakage the UF6 of emergence in the gasification tank of externally be observed and monitor to can in time report to the police, prevent severe accident's emergence.
Description
Technical field
This utility model belongs to nuclear fuel element manufacturing technology field, is specifically related to a kind of UF6Gas leak detection sampler.
Background technology
Dry process prepares UO2Powder production is by by solid UF6Heating, is passed through reburner, reacts under certain condition, final prepared UO after special handling2Powder.
Wherein solid UF6Heating and gasifying operation be to will be equipped with UF6The gasification tank heating sealed sent into by the container of solid, and after reaching certain temperature and pressure, Open valve, by UF6Gas is passed through reburner and reacts.
Due to UF6Hazard of gas is high, and once a large amount of leakages will produce baneful influence.In process of production, if UF6Leak outside gasification tank, by with the steam vigorous reaction in air, phenomenon is more obvious, and monitoring means is more；But UF6Leak in gasification tank, due to the containment role of gasification tank, be difficult to from outside directly observe and monitor.
When UF occurs in gasification tank6During leakage, if finding the most in time, the UF of leakage6Airduct may be entered by the evacuated tube of gasification tank, when the gas eluting column drip washing effect that airduct connects is bad, the UF of leakage6Directly may enter air from blower fan, serious Environment Pollution Event will be caused.
Utility model content
This utility model technical issues that need to address are: in existing technology, the UF occurred in gasification tank6Leakage cannot directly be observed from outside and monitor.
The technical solution of the utility model is as described below:
A kind of UF6Gas leak detection sampler, including: tank body (1), air inlet (2), overfall (3), air vent (4), deionized water inlet (5), emissive plastic glazing (6) and electrical conductivity gauge head (7)；Wherein, described tank body (1) is cylindrical tank, and air inlet (2) is arranged at the bottom of tank body (1), and air inlet (2) is connected to UF6The gas sample pipeline of gasification tank, from UF6The gas that gasification tank samples out is continued in tank body (1) by air inlet (2)；Overfall (3) is provided with tank body (1) top, when in tank body (1), liquid level is too high, by overfall (3) overflow, it is ensured that the liquid level in tank body (1) maintains in the reasonable scope；Air vent (4) is arranged at the top of tank body (1), the discharge of gas in tank, and air vent (4) is connected to airduct；Described deionized water inlet (5) is arranged at the top of tank body (1), for injecting deionized water in tank；Described emissive plastic glazing (6) is arranged on tank body (1), and emissive plastic glazing (6) is transparent, for observing the liquid level in tank body；Described electrical conductivity gauge head (7) is arranged at the middle part of tank body (1), for detecting the electrical conductivity of pot liquid.
The beneficial effects of the utility model are:
Use device of the present utility model, it is possible to from outside directly to the UF occurred in gasification tank6Whether leak and observe and monitor, it is therefore prevented that the generation of major accident.
Accompanying drawing explanation
Fig. 1 is UF of the present utility model6Gas leak detection sampler structural representation；
Wherein, 1-tank body, 2-air inlet, 3-overfall, 4-air vent, 5-deionized water inlet, 6-emissive plastic glazing, 7-electrical conductivity gauge head.
Detailed description of the invention
Below in conjunction with the accompanying drawings with embodiment to a kind of UF of the present utility model6Gas leak detection sampler is described in detail.
Gas hex can occur following reaction when meeting water:
UF6+H2O→UO2F2+4HF
This reaction will complete in very short time, produces a large amount of negative ions, electrical conductivity of water will be caused to steeply rise in solution.
UF of the present utility model6Gas leak detection sampler is as it is shown in figure 1, include: tank body 1, air inlet 2, overfall 3, air vent 4, deionized water inlet 5, emissive plastic glazing 6 and electrical conductivity gauge head 7.
Described tank body 1 is cylindrical tank, and air inlet 2 is arranged at the bottom of tank body 1, and air inlet 2 is connected to UF6The gas sample pipeline of gasification tank, from UF6The gas that gasification tank samples out is continued in tank body 1 by air inlet 2.Overfall 3 is provided with tank body 1 top, when in tank body 1, liquid level is too high, by overfall 3 overflow, it is ensured that the liquid level in tank body 1 maintains in the reasonable scope.Air vent 4 is arranged at the top of tank body 1, the discharge of gas in tank, and air vent 4 is connected to airduct.Described deionized water inlet 5 is arranged at the top of tank body 1, for injecting deionized water in tank.Described emissive plastic glazing 6 is arranged on tank body 1, and emissive plastic glazing 6 is transparent, for observing the liquid level in tank body.Described electrical conductivity gauge head 7 is arranged at the middle part of tank body 1, for detecting the electrical conductivity of pot liquid.
Device of the present utility model in use, injects deionized water by deionized water inlet 5 in tank body 1, and the water level of deionized water should be able to flood electrical conductivity gauge head 7 completely.From UF6The gas that gasification tank samples out is entered in tank body 1 by lasting air inlet 2.The gas sampled out and deionized water drain into airduct from air vent 4 after being fully contacted, and by the conductivity variations situation of liquid in electrical conductivity gauge head 7 examinations tank body 1, as electrical conductivity steeply rises, then UF are described6UF is had in gasification tank6Gas overflowing.Observe the liquid level in tank body 1 by machine windowpane 6, if liquid level is less than the installation site of electrical conductivity gauge head 7, then need to supplement deionized water in time.
