Description
Technical field
The utility model relates to art of refrigeration units, especially a kind of hybrid refrigeration cryogen matching device.
Background technology
Hybrid refrigeration is usually used in natural gas liquefaction and light ends unit, cold-producing medium of a great variety, can reach more than five kinds.When carrying out refrigeration cryogen proportioning, conventional way arranges refrigerant storage container to often kind of cold-producing medium, and each reservoir vessel is furnished with flowmeter, flowmeter is utilized to control the content of various cold-producing medium in azeotrope, the equipment of this proportioning mode is various, cost is higher, is applicable to big-and-middle-sized natural gas liquefaction and light ends unit.In the area that some are remote, because condition is limited, mostly adopt small-sized natural gas liquefaction device, and need often resettlement, if with conventional mode proportioning hybrid refrigeration cryogen, equipment is more, heavier, and carrying amount is large, increases the cost of enforcement.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of device requirement amount is few, convenient in carrying, cost-saving hybrid refrigeration cryogen matching device.
The utility model solves the technical scheme that its technical problem adopts: hybrid refrigeration cryogen matching device, comprise the metering device for measuring refrigerant cylinder weight, pipeline and mix refrigerant holding vessel, described pipeline one end is refrigerant cylinder link, the other end is connected with mix refrigerant holding vessel, and described pipeline is provided with valve.
Further, the by-pass line of described pipeline is provided with heater.
Further, described metering device is that explosion-proof electronic claims.
Further, be provided with data-signal control system, described data-signal control system claims to be connected with explosion-proof electronic.
Further, described valve is the automatic valve controlled by data-signal control system.
The beneficial effects of the utility model are: former hybrid refrigeration cryogen proportioning mode is applicable to big-and-middle-sized natural gas liquefaction device, and equipment is various, and cost is high, is not suitable for skid, is unfavorable for that device is moved.And the utility model utilizes meausring apparatus, the cold-producing medium weighing, calculate each refrigerant cylinder enters the quality of mix refrigerant holding vessel, adopts the mode of quality proportioning, makes the ratio of various cold-producing medium more accurate, reaches better refrigeration.Refrigerant storage container larger for original volume is changed the refrigerant cylinder for small volume, more saves space; Do not need multiple flowmeter, reduce device requirement amount, reduce cost, be more adapted to small-sized skid-mounted natural gas liquefaction device.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model hybrid refrigeration cryogen matching device.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, hybrid refrigeration cryogen matching device of the present utility model, comprise the meausring apparatus 1 for measuring refrigerant cylinder 2 weight, pipeline 4 and mix refrigerant holding vessel 3, described pipeline 4 one end is refrigerant cylinder link, the other end is connected with mix refrigerant holding vessel 3, and described pipeline 4 is provided with valve 5.
Former hybrid refrigeration cryogen is applicable to big-and-middle-sized natural gas liquefaction device, and equipment is various, and cost is high, is not suitable for skid, is unfavorable for that device is moved.And the utility model adopts bottled cold-producing medium, volume is less, more saves space, and weight is lighter, is convenient to carrying and weighs; During proportioning, do not need to use other auxiliary equipment, reduce device requirement amount, reduce cost.Utilize meausring apparatus 1 to weigh, calculate the quality that the cold-producing medium of each refrigerant cylinder 2 enters mix refrigerant holding vessel 3, realize quality proportioning, because the quality of cold-producing medium is not by the impact of external environment, makes the ratio of various cold-producing medium more accurate, reach better refrigeration.When using this mix refrigerant matching device, refrigerant cylinder 2 is connected with pipeline 4, is placed on meausring apparatus 1, record the reading S of now meausring apparatus 1; The requirement quality M of cold-producing medium is calculated again according to the ratio of configuration; Open valve 5 again, the cold-producing medium in refrigerant cylinder 2 enters in mix refrigerant holding vessel 3 by pipeline 4 under the effect of internal high pressure; Observe the reading of meausring apparatus 1, until when reading is shown as S-M, valve-off 5, and pipeline 4 is disassembled from refrigerant cylinder 2.Change the refrigerant cylinder 2 of the another kind of cold-producing medium of splendid attire, repeat aforesaid operations, until proportioning completes.Mix refrigerant holding vessel 3 is manufactured by carbon steel, and for being mixed by various refrigerant storage, after proportioning completes, mix refrigerant holding vessel 3 connects refrigeration system 8, mix refrigerant is passed into refrigeration system 8 and freeze.Pipeline 4 can adopt with refrigerant cylinder 2 and be threaded, and also can connect with quick detach joint.
Because indivedual cold-producing medium is high pressure, as ethene, under reduced pressure because throttling is less than, the temperature of cryogen can reduce, and because refrigerant storage tank 3 is carbon steel material, meets low temperature meeting embrittlement, so be provided with the heater 6 of bypass on pipeline 4, when installing the bottled cryogen of high pressure additional, just by the bypass heater 6 of pipeline 4, enter cryogen holding vessel 3 by after cryogenic coolant re-heat to normal temperature.When installing low pressure cryogen additional, then directly enter cryogen holding vessel 3 by pipeline 4.
Described meausring apparatus 1 claims for explosion-proof electronic.Explosion-proof electronic weighs more accurate, and reading is more convenient, and has explosion-resistance characteristic, meets the requirement of safety in production.
In order to ensure the instantaneity of reading, the automation mechanized operation of metering and accuracy, be provided with data-signal control system 7, described data-signal control system 7 claims to be connected with explosion-proof electronic.Described valve 5 is the automatic valve controlled by data-signal control system 7.Record by data-signal control system 7 reading that explosion-proof electronic claims, and control the open and close of automatic valve, more instant more rapidly than Non-follow control, guarantee the precise of cold-producing medium, and realize automated production.
