Abstract
The utility model discloses the structure of a liquifying canning apparatus for low-temperature nitrogen. The large-sized low-temperature liquid container is connected with a small Dewar type container through a vacuum thermal insulation pipeline, a low-temperature valve, a liquid helium delivering Dewar pipe with a heat exchanger, a liquifier and a low-temperature valve are arranged between the large-sized low-temperature liquid container and the small Dewar type container. The efficiency of the utility model is 5.6 times as great as the efficiency of using normal-temperature helium to produce liquid helium and the utility model is a liquifying canning apparatus for low-temperature nitrogen with a good application market.
Description
The utility model relates to the fluid tank of gas phase, gas-liquid two-phase or liquid phase goes into the interior transmitting set of container.
After liquid helium creates, all be to deposit in the big main storage tank so that transportation, wait transport to the destination after, divide again to install in the little storage Dewar, so that the user uses.ZL96223550.4 number " and the liquid helium transmission Dewar pipe of band heat exchanger " patent discloses a kind of novel perfusion tube, its throttle efficiency, and the liquid helium loss has all improved many than prior art.
The purpose of this utility model is, provides a kind of low temperature helium liquefaction canned device, can make the helium ability bring up to 5.6 times.
Below in conjunction with accompanying drawing, the utility model is elaborated:
Accompanying drawing 1 is a structural drawing of the present utility model.
Among the figure: 1, little Dewar type container; 2, vacuum heat-insulated pipe; 3, liquifier; 4, the liquid helium transmission Dewar pipe of band heat exchanger; 5, large-scale low-temperature liquid helium container; 6,7, Subzero valve.
Structure of the present utility model is as shown in Figure 1: large-scale low-temperature liquid container 5 is through vacuum heat-insulating pipe Together 2 link to each other with little Dewar type container 1, Subzero valve 6 is housed therebetween, transmits with the liquid helium of heat exchanger Dewar pipe 4, liquefier 3, Subzero valve 7.
The course of work of the present utility model is: the cold conditions gas helium in the large-scale low-temperature liquid container 5 is through low Temperature valve 6, with the liquid helium delivering Dewar pipe 4 of heat exchanger, vacuum heat-insulated pipe 2 enters liquefier 3, Helium is liquefied as liquid helium after consuming some energy, through Subzero valve 7, and vacuum heat-insulated pipe 2 Pack in the little Dewar type container 1, for use.
Working principle of the present utility model is the cold that has utilized the cold conditions helium, thereby throttle efficiency is improved greatly.
Liquefying power of the present utility model is an example with the U.S.'s 1430 type liquifiers, can reach 192 liters/hour, improves 5.6 times than the efficient of producing liquid helium with the normal temperature helium.With 10 yuan of calculating of per kilogram liquid helium cost of production, create beneficial result is 1580 yuan/hour.For this reason, the utility model is the canned device of a kind of helium of low temperature efficiently liquefaction, and fabulous application prospect is arranged.
Claims (1)
1. the canned device of low temperature helium liquefaction, comprise little Dewar type container, vacuum heat-insulated pipe, the liquid helium transmission Dewar pipe of band heat exchanger, the large-scale low-temperature liquid-container, Subzero valve is characterized in that the large-scale low-temperature liquid-container links to each other with little Dewar type container through vacuum heat-insulated pipe, and liquid helium transmission Dewar pipe, liquifier and the Subzero valve of Subzero valve, band heat exchanger is housed therebetween.
