Abstract
A kind of return-air low-temperature storage tank fast, belongs to Cryo Equipment and manufactures field.Perforated tube is become after water influent pipeline enters storage tank inner canister at the bottom of quick return-air low-temperature storage tank, the gas that pressure and temp is higher enters inner canister by pore and becomes tiny gas column, the little gas column of high-temperature fine rises and becomes tiny bubble in cryogenic liquide, and tiny bubble cools further and reduces gradually, and then liquefaction.Therefore achieve gas quick, thoroughly reclaim.
Description
Technical field
This practical tank car gas being newly solution low-temperature storage tank runs into when accepting cryogenic liquide reclaims difficult problem, belongs to Cryo Equipment and manufactures field.
Background technique
Cryogenic liquide (oxygen, nitrogen, argon, carbon dioxide, LNG) by liquid source through cryogenic liquid tank lorry accumulating to receiving terminal--low-temperature storage tank, being discharged to low-temperature storage tank from tank car all will, through the supercharging of cryogenic liquide pressurized machine to tank car, utilize pressure reduction that cryogenic liquide is depressed into low-temperature storage tank.Unsnatch the tank car of liquid with partial high pressure gas, now adopt the gas of tank car enter low-temperature storage tank the end (under) liquid inlet pipe to gas carry out liquefaction reclaim, but because water influent pipeline diameter is large, bubble very greatly and rise to liquid level fast, be difficult to cooling liquid, pressure of storage tank raises very fast, quick and tank car pressure balance, and then cannot gas recovery.This is all reluctant to see for user, transporter, and the LNG of high price particularly come for transporting for long-distance especially like this.Not only not only how also to be reclaimed into storage tank by the pressurized gas in tank car, and the speed reclaimed can not be very slow, reclaim soon but also thoroughly, this difficult problem annoyings people always.
Summary of the invention
the utility model-is fast at the bottom of return-air low-temperature storage tank (under) water influent pipeline becomes perforated tube after entering storage tank inner canister, the gas of higher temperature pressure enters inner canister by pore and becomes tiny gas column, the little gas column of high-temperature fine rises and becomes tiny bubble in cryogenic liquide, tiny bubble cools further and reduces gradually, and then liquefaction.Therefore achieve gas quick, thoroughly reclaim.
Accompanying drawing explanation
fig. 1, Fig. 2 are practical new structural representations
in figure 1, outer container 2, inner container 3, perforated tube 4, liquid inlet pipe be outside.
Embodiment
embodiment 1: the quick return-air low-temperature storage tank of one of the present embodiment, as shown in Figure 1, comprises 1 outer container, 2 inner containers, 3 perforated tubes, 4 liquid inlet pipes outsides.1 outer container, 2 inner containers are closed container, 3 perforated tubes, 4 liquid inlet pipes outside actual be two parts of a pipe, just name for convenience of explanation.The tank car of unsnatching liquid is connected with 4 liquid inlet pipe outsides, high temperature and high pressure gas in tank car enters 3 perforated tubes by 4 liquid inlet pipe outsides, enter inner canister by pore and become tiny gas column, the little gas column of high-temperature fine rises and becomes tiny bubble in cryogenic liquide, tiny bubble cools further and reduces gradually, and then is liquefied.Therefore achieve gas quick, thoroughly reclaim.
embodiment 2:: the quick return-air low-temperature storage tank of another kind of the present embodiment, as shown in Figure 2. the present embodiment is identical with embodiment 1 structure, and just two example one is vertical tank one is horizontal tank.
Claims (2)
1. a quick return-air low-temperature storage tank, is characterized in that liquid inlet pipe at the bottom of described low-temperature storage tank is perforated tube in inner container.
2. quick return-air low-temperature storage tank according to claim 1, it is characterized in that quick return-air low-temperature storage tank both can be vertical tank, also can be horizontal tank.
