Description
[technical field]
This utility model relates to a kind of liquid nitrogen filling equipment, particularly relates to a kind of liquid nitrogen charging device using cryogenic air separation method to produce.
[background technology]
Deep Cooling Method air separation principle is with air as raw material, through overcompression, purification, makes air fluid be melted into the way of liquid air separation and Extraction nitrogen, oxygen again with heat exchange.It has been widely used, owing in air, nitrogen content is abundant, unnecessary liquid nitrogen is directly being discharged after meeting self industrial requirement by generally enterprise, but although air cost can disregard be compressed into liquid nitrogen after again discharge waste the energy, it is necessary to by be filled in nitrogen cylinder after unnecessary liquid nitrogen vaporization again with or export trade to reduce enterprise operation cost.
【Utility model content]
Technical problem to be solved in the utility model is to provide a kind of liquid nitrogen charging device that the unnecessary liquid nitrogen that cryogenic air separation method obtains fills utilization.
Technical problem to be solved in the utility model is achieved through the following technical solutions: provide a kind of liquid nitrogen charging device in cryogenic air separation unit fractionating column device, including liquid nitrogen feedway, the cryogenic liquid pump being connected with liquid nitrogen feedway, the carburator being connected with cryogenic liquid pump and the row of filling being connected with carburator, it is provided with three-way valve between described cryogenic liquid pump and liquid nitrogen feedway, described three-way valve connects liquid nitrogen feedway respectively by the first pipeline and the second pipeline, and the 3rd pipeline connects carburator.
Further, described in the row of filling equipped with piezometer, be electrically connected with between described piezometer and cryogenic liquid pump.
Further, the nitrogen pressure of described carburator output is not less than 15MPa.
Further, after the upper connection of the row of filling described in has some nitrogen cylinders, described nitrogen cylinder to fill nitrogen, internal pressure is not less than 13.5MPa.
Compared to prior art, the unnecessary liquid nitrogen that the liquid nitrogen charging device in cryogenic air separation unit fractionating column device disclosed by this utility model produces when can preferably reclaim beneficially cryogenic air separation unit.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of the liquid nitrogen charging device meeting this utility model in cryogenic air separation unit fractionating column device.
[detailed description of the invention]
As shown in Figure 1, meet the liquid nitrogen charging device 100 in cryogenic air separation unit fractionating column device of the present utility model, including the liquid nitrogen feedway 10 being connected with cryogenic air separation unit fractionating column (not shown), the cryogenic liquid pump 30 being connected with liquid nitrogen feedway 10, the carburator 40 being connected with cryogenic liquid pump 30 and the row of filling 50 being connected with carburator 40, wherein, liquid nitrogen feedway 10 can be low temperature storage tank can also be the pipeline directly led out from cryogenic air separation unit fractionating column, it is connected by three-way valve 20 between liquid nitrogen feedway 10 with cryogenic liquid pump 30, described cryogenic liquid pump 30 is preferably plunger displacement pump, three-way valve 20 includes the first pipeline 21 and the second pipeline 22 being connected with liquid nitrogen feedway 10, and the 3rd pipeline 23 being connected with carburator 40.Liquid nitrogen in liquid nitrogen feedway 10 can be transported to carburator 40 by the first pipeline 21 and the 3rd pipeline 23, the row of filling 50 is flowed to after pressure build-up vaporized, preferably, nitrogen pressure after boosting is not less than 15MPa, and then the row of filling 50 distribution nitrogen is not less than 13.5MPa to facilitate the later stage to use to each nitrogen cylinder 52 to bottle internal gas pressure.
In the present embodiment, equipped with piezometer 41 on the trunk roads (non-label) of the row of filling 50, on branch road (non-label), piezometer 51 is installed, described piezometer 41, 51 respectively and are electrically connected with between cryogenic liquid pump 20 by holding wire (not shown) or are intercoupled by third party's controller (not shown), when the pressure in nitrogen cylinder 52 reaches setting value time, feed back signal to cryogenic liquid pump 20 stop carrying liquid nitrogen to carburator 40, unnecessary liquid nitrogen is reversely transmitted back to liquid nitrogen feedway 10 by the second pipeline 22 simultaneously, avoid waste and ensure safety in production.
Meeting the liquid nitrogen more than needed that the liquid nitrogen charging device 100 in cryogenic air separation unit fractionating column device disclosed in this utility model can effectively utilize cryogenic air separation unit fractionating column to produce, the nitrogen cylinder 52 being filled with stores for future use or sells and more can reduce enterprise operation cost.
