Abstract
The utility model relates to a rapid liquid collection device for a liquid hydrogen receiving container. The rapid liquid collection device comprises an inner container of the liquid hydrogen receiving container, wherein a liquid collection pipeline of which the bottom end is closed is vertically suspended in the inner container; a group of liquid outlet holes which are uniformly formed in the peripheral direction are formed in the liquid collection pipeline. By adoption of the rapid liquid collection device, the rapid liquid collection of the large/medium-sized liquid hydrogen receiving container can be realized, the device is good in safety performance, simple in structure and easy to implement, the precooling time is greatly shortened, and the waste of liquid hydrogen is obviously reduced.
Description
Technical field
The utility model relates to a kind of liquid collector, and especially a kind of quick liquid collector for liquid hydrogen receiving vessel, belongs to low-temperature pressure container technical field.
Background technique
The storage temperature of liquid hydrogen is generally below-253 DEG C, and its storage container is double-jacket vacuum insulation basin.Many employings are at present located at basin inner top, carry out liquid collecting through the liquid collector of spray precooling, its working principle is: in the situation that the liquid hydrogen daily output is limited, liquid hydrogen is entered by the inner container top of liquid hydrogen receiving vessel, and by spraying tube, inner container is carried out to overall precooling, this Pre-cooling Mode can not make the bulk temperature of inner container suddenly be reduced to liquid hydrogen temperature, therefore need carry out heat exchange with liquid hydrogen at a period of time inner container starting, the temperature of inner container is slowly reduced, liquid hydrogen is all vaporized.Because the bulk temperature of inner container reduces very slowly, cause liquid hydrogen in initial several days in container, not assemble, until inner container temperature just starts liquid collecting while dropping to liquid hydrogen temperature, pre-cool time is long, liquid hydrogen vaporization phenomenon is serious, can cause liquid hydrogen to waste.
Model utility content
The purpose of this utility model is: the problem existing for above-mentioned prior art, and propose one and can effectively shorten pre-cool time, reduce the quick liquid collector for liquid hydrogen receiving vessel of liquid hydrogen waste.
In order to reach above object, the utility model comprises the inner container of liquid hydrogen receiving vessel for the quick liquid collector of liquid hydrogen receiving vessel, its improvements are, are vertically hung with the liquid collecting pipeline of bottom sealing in described inner container, and described liquid collecting pipeline is shaped with one group of circumferential uniform liquid outlet opening.
The utility model further improves, and the top of described liquid collecting pipeline has liquid entering hole, and bottom has liquid outlet.The bottom liquid outlet of described liquid collecting pipeline is provided with blanking cover.
The utility model further improves, and described liquid collecting pipeline is arranged in inner container near lowest point.
The utility model further improves, and described liquid outlet opening is arranged on the middle and lower part of liquid collecting pipeline, and its gross area is equal to or greater than the cross-section area of liquid collecting pipeline.
The utility model has the advantage of: adopt liquid collector of the present utility model can realize the quick liquid collecting of big-and-middle-sized liquid hydrogen receiving vessel, Safety performance is good, simple in structure, easily realize, greatly shortened pre-cool time, significantly reduced the waste of liquid hydrogen.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the utility model embodiment one structural representation.
Fig. 2 is the structural representation of liquid collecting pipeline in the utility model.
Embodiment
Embodiment one
The present embodiment is for the quick liquid collector of liquid hydrogen receiving vessel, comprise the inner container 2 being arranged in liquid hydrogen receiving vessel, in inner container 2, be vertically hung with the liquid collecting pipeline 1 of bottom sealing, wherein liquid collecting pipeline 1 is Stainless Steel Tube, on it, be shaped with one group (10) circumferentially uniform liquid outlet opening 6, this group liquid outlet opening 6 is arranged on the middle and lower part of liquid collecting pipeline 1, and its gross area is equal to or greater than the cross-section area of liquid collecting pipeline 1.Separately, the top of liquid collecting pipeline 1 has liquid entering hole, and bottom has liquid outlet, and liquid outlet is provided with circular blanking cover 5, and liquid collecting pipeline 1 is arranged in inner container 2 near lowest point.
When use, liquid hydrogen enters liquid collecting pipeline 1 through top liquid entering hole, and gather in the bottom of liquid collecting pipeline 1, now the liquid outlet opening 6 of liquid hydrogen on liquid collecting pipeline 1 overflows and along tube wall landing, flow in the inner container 2 of liquid hydrogen receiving vessel, make the position between bottom and the liquid outlet of liquid collecting pipeline 1 have liquid hydrogen to exist always, cause the liquid outlet near zone of liquid collecting pipeline 1 to form a cold-zone (being district of topical hypothermia), this cold-zone can reach the temperature of liquid hydrogen very soon, by the outside precooling in this cold-zone, reach good precooling effect, therefore liquid hydrogen gathers in inner container 2 bottoms, the inner space of inner container 2 is divided into liquid hydrogen district 4, bottom and upper gaseous phase section 3, make the liquid collecting fast of big-and-middle-sized liquid hydrogen receiving vessel, solve the problem of big-and-middle-sized receiving vessel liquid collecting difficulty.
In addition to the implementation, the utility model also can have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
Claims (5)
1. for a quick liquid collector for liquid hydrogen receiving vessel, comprise the inner container of liquid hydrogen receiving vessel, it is characterized in that: in described inner container, be vertically hung with the liquid collecting pipeline of bottom sealing, described liquid collecting pipeline is shaped with one group of circumferential uniform liquid outlet opening.
