According to the utility model, gas of a gas-phase part in the liquid storage tank can be filled before the jump pressure of a safety valve is reached, and high-purity nitrogen gas that can be automatically depressurized can be recycled; natural consumption can be lowered, and about 10% of high-purity gas raw material cost can be saved; the recycle device is unique in design, safe, reliable and energy-saving.
Description
Technical field
The utility model relates to gas and reclaims field, and the high-purity gas enforcement of in industrial gas filling process, raw material liq storage tank being vaporized partly is naturally reclaimed, particularly a kind of gas liquid storage tank pressure release emptying recycle device.
Background technique
High pure nitrogen, high-purity argon gas and high purity oxygen gas are all respectively purposes gas very widely in industrial production, after separating liquefaction, transport, store before this entering in point process of assembling with liquid state in air.
High pure nitrogen, high-purity argon gas and high purity oxygen gas in the flow process that fills into gaseous state gas cylinder are: empty subsidiary factory separates airborne nitrogen, and---------liquid tank boxcar transports---liquid charging stock storage tank stores---pressure liquid pump---air vaporizer---high-pressure cylinder bottle group fills----bottled high pure nitrogen finished product in wet tank storage in liquefaction.
Liquid nitrogen, the vapourizing temperature of liquid argon gas and liquid oxygen extremely low (190 ℃), although storage tank has insulation, but in air, naturally have for a long time a considerable amount of liquid nitrogens and can be vaporized into gaseous nitrogen, liquid argon can be vaporized into gaseous state argon, liquid oxygen can be vaporized into gaseous oxygen, be enriched in liquid charging stock tank body, due to liquid nitrogen, liquid argon gas, the pressure of liquid oxygen head tank generally all only has 1MPa left and right, the nitrogen of enrichment, argon gas or oxygen pressure can rapid superchargings, for preventing wet tank blast, tank body is provided with safety valve protection, while arriving 1MPa, safety valve can automatic take-off, by the nitrogen of enrichment, argon gas or oxygen are to aerial pressure release.The higher liquid nitrogen of temperature, liquid argon gas, the vaporization of liquid oxygen are more, and safe take-off pressure release number of times is more, wastes also manyly, conventionally can reach 10% left and right of finished product consumption, badly influence the cost of production of high-purity gas.
Meanwhile, because nitrogen, argon gas or the oxygen of enrichment can produce bubble in liquid nitrogen, liquid argon gas, liquid oxygen, can badly influence the service behaviour of pressure liquid pump, and can damage the parts of pressure liquid pump.
Model utility content
Model utility object of the present utility model is the shortcoming in order to overcome above-mentioned background technology, provides a kind of design ingenious, safe and reliable, energy-conservation, and repacking is easy to the recycle device of liquid gas storage tank enriched gas.
The technical solution of the utility model is: a kind of gas liquid storage tank pressure release emptying recycle device, it comprises: gas liquid storage tank, pressure liquid pump, air vaporizer, knock out drum, gas compressor, gas cylinder fills group, gas phase connecting tube, described high-purity gas wet tank top gas phase mouth is connected with air vaporizer by gas phase connecting tube, complete the recovery approach of pressure release nitrogen, gas liquid tank bottom liquid phase mouth is connected with pressure liquid pump, described pressure liquid pump is connected with air vaporizer, described air vaporizer is provided with two pipelines, wherein a pipeline directly fills to organize with gas cylinder by gas phase connecting tube and is connected, this pipeline is normally to fill the subordinate line pipeline doing, in the time not needing to reclaim the enriched gas of high-purity gas wet tank, use, another pipeline is connected with knock out drum entrance, described knock out drum top exit is provided with pipeline and is connected with gas compressor intakeport, the enriched gas of high-purity gas wet tank is introduced to gas compressor, described gas compressor relief opening fills group entrance with gas cylinder and is connected, complete the connection that fills overall process, and can implement reclaim fill.
Described gas liquid storage tank is high pure nitrogen wet tank, high-purity argon gas wet tank and high purity oxygen gas wet tank.
The beneficial effects of the utility model are: the utility model is by being connected with air vaporizer nitrogen, argon gas or oxygen liquid emptying storage tank pipe, after being connected with gas compressor intakeport, can be by before safety valve jumping up pressure, gas phase portion gas in nitrogen, argon gas or oxygen wet tank is implemented to fill, will originally can be recycled by self-relieving high pure nitrogen.Can reduce natural wastage, save High Purity Nitrogen cost of material 10% left and right, the utility model design is ingenious, safe and reliable, energy-conservation.
