Abstract
The utility model relates to an emptying liquid-stopping structure of low-temperature liquid storage and transportation equipment, which comprises an internal container, a liquid-stopping cover (2) and an emptying pipe (3), wherein the upper end of the liquid-stopping cover (2) and the inner wall of the top part of the internal container (1) are welded together, the upper part of the liquid-stopping cover (2) is provided with a notch (4), and the emptying pipe (3) extends into the liquid-stopping cover (2). The structure can stop low-temperature liquid in the equipment when the low-temperature liquid storage and transportation equipment conducts air-phase emptying, so that the liquid can not enter the emptying pipe, thus improving the safety of the storage and transportation equipment during emptying.
Description
Technical field
The utility model relates to a kind of cryogenic liquide storage and transportation equipment emptying liquid baffle structure.Be used for the gas phase emptying of cryogenic liquide storage and transportation equipment.
Background technique
The cryogenic liquide storage and transportation equipment because pressure sharply descends, causes cryogenic liquide volumetric expansion and boiling in the equipment in that pressure is higher when needing emptying, and partially liq can flow to along with dropping a hint into blow-down pipe and discharge, and can cause the injury of personnel and equipment.
Summary of the invention
The purpose of this utility model provides a kind of cryogenic liquide storage and transportation equipment emptying liquid baffle structure, can when the emptying of cryogenic liquide storage and transportation equipment gas phase cryogenic liquide be kept off in equipment, does not enter blow-down pipe.
The technological scheme that realizes above-mentioned purpose is: a kind of cryogenic liquide storage and transportation equipment emptying liquid baffle structure, comprise inner container, also comprise retaining liquid cover and blow-down pipe, the upper end of retaining liquid cover and the top inner wall welding of inner container, and the top of retaining liquid cover has breach, and blow-down pipe extend into retaining liquid cover inside.
Above-mentioned breach is crescent shape.
After adopting technique scheme, because the breach on the retaining liquid cover leaves the top at retaining liquid cover, when the cryogenic liquide storage and transportation equipment in that pressure is higher when needing emptying, the emptying air-flow enters retaining liquid cover from breach, enter blow-down pipe then, the expansion of liquids cause and the partially liq of boiling are kept off liquid cover retaining in inner container because pressure descends, thus the Security when improving the emptying of storage and transportation equipment gas phase.
Adopt the crescent shape breach more to help dropping a hint to flow to the blow-down pipe in the retaining liquid cover.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, a kind of cryogenic liquide storage and transportation equipment emptying liquid baffle structure comprises inner container 1, retaining liquid cover 2 and blow-down pipe 3, the upper end of retaining liquid cover 2 and the top inner wall welding of inner container 1, and the top of retaining liquid cover 2 has crescent shape breach 4, and blow-down pipe 3 extend into retaining liquid cover 2 inside.
Working principle of the present utility model is as follows:
When the cryogenic liquide storage and transportation equipment in that pressure is higher when needing emptying, the emptying air-flow enters retaining liquid cover 2 from crescent shape breach 4, enters blow-down pipe 3 again the expansion of liquids that causes and the partially liq of boiling are kept off liquid cover 2 retainings in inner container 1 because pressure descends.
Claims (2)
1. cryogenic liquide storage and transportation equipment emptying liquid baffle structure, comprise inner container, it is characterized in that: also comprise retaining liquid cover (2) and blow-down pipe (3), the upper end of retaining liquid cover (2) and the welding of the top inner wall of inner container (1), and the top of retaining liquid cover (2) has breach (4), and blow-down pipe (3) extend into retaining liquid cover (2) inside.
2. cryogenic liquide storage and transportation equipment emptying liquid baffle structure according to claim 1, it is characterized in that: described breach (4) is for being crescent shape.
