Description
Technical field
The utility model relates to the device that a kind of gas reclaims and purifies, the recovery and the purification plant of the gasifying gas when particularly a kind of liquid argon gas fills.
Background technique
The scene does not have the industrial gas fueling station of cryogenic air separation plant at present, all adopt liquid canned form transportation for high-pure gas such as oxygen, nitrogen, argons, liquid gas is canned in the tank car storage tank, because the tank car storage tank is in normal temperature during canned beginning, the liquid gas that charges into will gasify rapidly, and the tank car tank body is cooled off fast simultaneously, after liquid, gas temperature of equilibrium, be full of jar, this part gas need be released.
After tank car was finished transportation, the liquid in its storage tank charged in the low-temperature storage tank and stores, so that charge into liquid gas at any time in Dewar vessel.During to the low-temperature storage tank topping up, the tank car storage tank needs constantly pressurization at the liquid of tank car storage tank, when canned finishing, and the just remaining gaseous state gas of high pressure in the storage tank, this part gas must discharge before the tank car storage tank is freighted once more.
At the tank car storage tank during to the refrigerated storage tank topping up, the saturated and pressure of low-temperature storage tank internal cause heat absorption raises, and needs relieving pressure to keep not superpressure of topping up engineering and jar internal pressure.
And Dewar vessel is when being charged into liquid gas, and the gas of gasification need constantly be released in the bottle, to keep the low-pressure state in the bottle.
The gasification that these need be released gas, if can recycle, will save cost of production greatly.Because the market price of argon gas will be several times as much as oxygen and nitrogen, therefore the Economy that in the practical application of argon gas this part gas of releasing is reclaimed can be very considerable.
In addition, the specification demand of argon gas is divided general argon (99.9%), straight argon (99.99%), high purity argon (99.999%), ultrapure argon (99.9999%) by NBS, general supply station need be provided with a plurality of liquid storage vessels or with the gas supply of a high grade when supply different purity product.The gas of three specifications of three storage tanks of producer's operated by rotary motion supply, wherein ultrapure argon is purchased from the outside, because the high purity argon and the super spring argon market price are very high, has caused the rising of cost of production, and can't reclaim the gas of having released in process of production, has caused waste.
Summary of the invention
The utility model is in order to overcome above-mentioned shortcoming, provide a kind of can the especially liquid argon gas reclaiming clean of liquid towards high-pure gas device.
The technical solution of the utility model is: a kind of cryogenic gas reclaiming clean device, comprise gas recovery system and gas purge system, gas recovery system comprises the tank car storage tank, during connecting respectively, the tank car storage tank presses energy-conservation jar and low-temperature storage tank, low-temperature storage tank connects Dewar vessel, presses energy-conservation jar during Dewar vessel connects, and the energy-conservation jar of middle pressure connects gas purge system by reduction valve, gas purge system connects low pressure buffer jar and compressor successively, and compressor deliver a gas to canned district by the pipeline connection.
Described gas purge system comprises Electric furnace, reactor, heat exchanger, vacuum pump, filter, wherein heat exchanger inlets 1 is pressed energy-conservation jar in connecting by reduction valve, heat exchanger outlet 1 coupled reaction device import, reactor is provided with Electric furnace outward, and reactor outlet connects heat exchanger inlets 2, heat exchanger outlet 2 connects vacuum pump and filter successively by pipeline, connects compressor behind the filter.
The utility model provides a kind of can reclaim the overpressure relief gas of tank car storage tank residual air, low-temperature storage tank and the reclaiming clean device that Dewar vessel discharges gas simultaneously, making gas products reduce loss when filling also can purify to reclaiming gas, system flow and operating process are simple, and Economy is strong.
