The rare gas exhaust recovery device mainly comprises a rare gas source, an air bag, a gas storage tank, a vacuum pump, a freezing cylinder, a filling bench and connecting pipelines, wherein the inlet of the air bag is connected with the rare gas source by a pipeline, the outlet of the air bag is connected with the gas storage tank by a pipeline, the gas storage tank is connected with the vacuum pump and the freezing cylinder respectively by pipelines, the freezing cylinder is connected with the filling bench by a pipeline, check valves are arranged at the inlet pipeline and the outlet pipeline of the air bag, a safety valve is arranged on the air bag, and a gas pressure gauge and a rupture disk are arranged on the gas storage tank and the pipeline between the freezing cylinder and the filling bench. The rare gas exhaust recovery device adopts a freezing method for absorbing the tail gas and filling the gas into the cylinder, is simple in equipment, and convenient and fast, and has high working efficiency and tremendous recovery benefit.
Description
Technical field
The utility model relates to a kind of rare gas gathering-device, relates in particular to a kind of rare gas device for recovering tail gas.
Background technique
In rare gas production and analysis using process, gas tail gas such as expensive krypton, xenon are discharged usually, cause very big waste.Krypton xenon-133 gas tail gas comprises that analysis fills with krypton xenon-133 gas tail gas and daily use krypton xenon-133 gas tail gas etc. with krypton xenon-133 gas tail gas, steel cylinder, because this part krypton xenon-133 gas tail gas amount is considerably less, and pressure is very low, there is not good way to reclaim before, existing rare gas device for recovering tail gas utilizes molding machine to carry out air-breathing and inflation, the pressure difference that can provide is very low, and effect is undesirable.
The model utility content
The purpose of this utility model is to overcome the prior art defective, and a kind of rare gas device for recovering tail gas is provided.
The technical solution of the utility model is achieved in that a kind of rare gas device for recovering tail gas, mainly by rare gas source of the gas, air bag, gas holder, vacuum pump, freezing bottle, fill platform and connecting tube is formed, the air bag import links to each other with the rare gas source of the gas by pipeline, the air bag outlet links to each other with gas holder by pipeline, gas holder also links to each other with freezing bottle with vacuum pump respectively by pipeline, and freezing bottle fills platform by the pipeline connection.
Preferably, on air bag import and outlet conduit, be equipped with safety check.
Preferably, safety valve is housed on air bag.
Preferably, on the gas holder and freezing bottle and fill on the connecting tube between the platform and be equipped with gas pressure gage and rupture disk.
The utility model characteristics:
1, adopt this device to reclaim rare gas, prepare a rubber pneumatic bag is used for krypton xenon tail gas as collection pans earlier, after treating that it collects certain volume rare gas tail gas, carry out next step recovery operation, and on the admission line of air bag, add safety check, prevent gas backstreaming pipeline or the source of the gas extremely before in the air bag, then discharge when gasbag pressure is too high by safety valve.
Secondly, with vacuum pump gas holder is vacuumized, treat its internal pressure be lower than before behind air bag and the pipeline pressure, can make the rare gas tail gas in the air bag enter gas holder automatically by valve control, in like manner, before gas holder, add on the admission line safety check prevent in the gas holder gas backstreaming to before pipeline or air bag.
Once more, when the gas build in the gas holder to a certain degree the time, freezing bottle is watered liquid nitrogen frozen, freezing pressure of the inside of a bottle is reduced, produce negative pressure, the gas in the gas holder is drawn in the freezing bottle, and is in a liquid state.
At last, close freezing bottle early gate, water freezing bottle with normal-temperature water, the rare gas in the freezing bottle expands, and pressure raises, and fills bottle by filling platform.
2, carry out in the gas filling process, the processing ease of pipeline valve and gas cylinder valve causes local superpressure in the pipeline, but pipeline pressure table real-time monitored exhaust duct pressure, so that regulate; Rupture disk plays a protective role when pipeline pressure is excessive, in case superpressure then release is carried out in the rupture disk explosion has guaranteed that all discharge process steadily carries out.
3, the utility model adopts " freezing " to carry out air-breathing to gas tail gas and fills bottle, and equipment is simple, and is convenient and swift, high working efficiency, and the price of every cubic metre of krypton gas and xenon is ten thousand yuan of 1-3, it is huge to reclaim benefit.

Embodiment
Be further described below in conjunction with accompanying drawing:
As shown in the figure, a kind of rare gas device for recovering tail gas, mainly by rare gas source of the gas 1, air bag 3, gas holder 7, vacuum pump 10, freezing bottle 16, fill platform 17 and connecting tube 19 is formed, air bag 3 imports link to each other with krypton xenon source 1 by flexible pipe, air bag 3 outlets link to each other with gas holder 7 by pipeline 19, gas holder also links to each other with freezing bottle 16 with vacuum pump 10 respectively by pipeline, and freezing bottle 16 fills platform 17 by the pipeline connection; On air bag 3 imports and outlet conduit, be equipped with safety check 2; Safety valve 4 is housed on air bag 3; On the gas holder 7 and freezing bottle 16 and fill on the connecting tube between the platform 17 and be equipped with gas pressure gage 8 and rupture disk 9.
Operating procedure:
1, rare gas source of the gas 1 tail gas enters air bag 3, and air bag 3 pressure are a little more than barometric pressure.
2, gas is heaved in air bag 3, and gas volume reaches at 80% o'clock, earlier gas holder inlet valve 6, outlet valve 11 is closed, and uses 10 pairs of gas holder 7 of vacuum pump to vacuumize then.
3, vacuumize end after, close vacuum pump 3 and connect valves, open gas holder inlet valve 6, rely on pressure difference that the gas in the air bag 3 is sucked gas holder 7.Use when this step only comes into operation in system, after this need not this step of repetition.
4, gas holder outlet valve 11 is opened, closed and fill platform suction valve 15, water freezing bottle 16 with liquid nitrogen simultaneously, then the gas in gas holder 7 and the air bag 3 can be sucked into freezing bottle 16, when also remaining the gas of 20%-30% to air bag, stops freezing.At this moment, the gas of recovery stores with liquid form in freezing bottle 16.
5, to after the freezing end of tail gas in the freezing bottle 16, close gas holder outlet valve 11, watering to freezing bottle 16 makes in the bottle liquid fully vaporize the pressure rising, open simultaneously and fill platform suction valve 15 and cylinder valve to be filled, gas enters steel cylinder and exists with gaseous form.
6, treat that the pressure in the steel cylinder rises to about 13.5MPa, gas filling finishes, and closes steel cylinder frame air intake valve and cylinder valve.
7, the steel cylinder of depositing tail gas is sent to purifier apparatus and is further purified.
