Description
Technical field
The technical field that the invention belongs to be pressurized uranic hexafluoride gas in nuclear industry uranium conversion industry, and in particular to
It is a kind of using compressed air as the small flow UF of power6Gas pressurized device.
Background technique
In the fluorination process of uranium conversion production, mainly by UF4With F2Reaction generates UF6Product is gaseous state, is claimed
For furnace gas.To guarantee UF4With F2Sufficiently reaction, should be added excessive F2.But if excessive addition F2Not only waste material but also
Make postorder to residual F2Processing difficulty increase, be unfavorable for environmental protection.Pass through F in detection furnace gas2Content can preferably control F2's
Additional amount can reduce cost and be conducive to environmental protection again.Comprehensive country's state of the art and ability detect UF using chromatography6Furnace
F in gas2Content.But UF in process of production6Furnace gas is micro-positive pressure, if to carry out on-line analysis using chromatograph, it is necessary to be just
It is pressed into sample.Simultaneously as UF6Gas easily condenses at normal temperature, to keep the temperature to material while needing to be pressurized.Therefore,
Will test medium to be promoted by slight positive pressure state highest to 0.3MPa and maintain the temperature at 80 DEG C or more, can be only achieved it is chromatographic into
Gas sampling request.The country is existing can be by UF6The device of gas boosting is ftercompction machine, dedicated sieve of external You Laibao company production
Thatch pump, but all it is used in UF6The biggish occasion of gas flow, and amplitude of boosting is much smaller than 0.3MPa.
Summary of the invention
The present invention measures UF for chromatography6F is remained in furnace gas2UF when content6Gas flow is smaller and boosts amplitude very
High feature can be steadily by UF by the method that piston compresses using compressed air as power6Gas boost is to 0.3MPa.
In order to achieve the above objectives, the technical solution used in the present invention are as follows:
It is a kind of using compressed air as the small flow UF of power6Gas pressurized device, connecting plate are installed on the upper cover, in upper cover
Close bottom at be drilled with proper crossover stomata pass to driving gas side piston, driving gas side piston and upper cover using flange company

It is obtained by the present invention to have the beneficial effect that
The present invention can be steadily by UF by the method that piston compresses6Gas boosts to 0.3MPa by 60kPa, and guarantees defeated
Gas pressure is constant out, reaches chromatograph sample introduction is analyzed and require.Firstly, Pneumatic booster device can automatic pressure-maintaining and pressure maintaining not
Energy consumption；When work, the rapid working in reciprocating mode of Pneumatic booster device, the reciprocal fortune of piston when with output pressure close to setup pressure value
Dynamic speed reduces until stopping.And this pressure is kept, energy consumption very little, empty calory generate at this time, no part movement.Work as pressure
Dynamic balance is broken, and Pneumatic booster device automatically begins to work to next balance, can guarantee that output gas pressure is constant.Secondly,
Cylinder is kept the temperature using ribbon heater so that temperature of charge is constant.It is examined by verifying, which can be quickly by U
F6Gas is promoted to 0.3MPa by micro-positive pressure and maintains the temperature at 80 DEG C or more, meets chromatograph air inlet sampling request.The dress
It sets and applies on production line at the scene, stable and reliable operation.
