Further, tank body Bonding pressure sensor, can automatically start according to pressure change or cut out the power supply of refrigerator, make cooling procedure more accurate, reduce human error.
The gas station that the utility model provides comprises above-mentioned storage tank, and because above-mentioned storage tank has above-mentioned technique effect, above-mentioned gas station also should have same technique effect, introduces no longer in detail at this.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of storage tank provided by the utility model.
Embodiment
Core of the present utility model is to provide a kind of storage tank of gas station, slows down the gasification rate of LNG Liquefied natural gas in storage tank and tank internal pressure is stablized, prevent non-essential emptying.Another core of the present utility model is to provide a kind of gas station comprising above-mentioned storage tank, by preventing the liquefied natural gas gasifying in storage tank from causing tank internal pressure to raise, and then prevents the waste because non-essential emptying causes.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of embodiment of storage tank provided by the utility model.
In this embodiment, LNG Liquefied natural gas loads in tank body 1, and is outside equipped with refrigerator 3 at tank body 1, and cryogen outlet and the cryogen entrance of refrigerator 3 are connected the two ends of heat exchange container respectively, cryogen can not be mixed with LNG Liquefied natural gas, and heat exchange container and tank body 1 conduct heat and arrange.Each jointing ensures to seal well, and LNG Liquefied natural gas and cryogen all can not be revealed.
When the affected by environment and Quick-gasifying of the LNG Liquefied natural gas in tank body 1, start refrigerator 3, cryogenic coolant exports by the cryogen of refrigerator 3 one end entering heat exchange container.By heat conducting mode, cryogenic coolant and the higher LNG Liquefied natural gas of relative temperature carry out heat exchange, and namely cryogenic coolant reduces the temperature of LNG Liquefied natural gas in tank body 1 by heat exchange container, and the LNG Liquefied natural gas gasified that again liquefies.High temperature cryogen after heat exchange enters the cryogen import of refrigerator 3 by the other end of heat exchange container, cooling down in refrigerator, and cooled cryogen enters heat exchange container again, so circulates, and realizes the cooling to LNG Liquefied natural gas in tank body 1.By the above-mentioned type of cooling, slow down the gasification rate of LNG Liquefied natural gas, maintain the stable of tank inner pressure, and then prevent the waste because non-essential emptying causes.
Heat exchange container can have various ways; cooling tube 2 can be specially; cryogen circulation in pipe has stronger directivity; prevent due to cryogenic coolant and high temperature cryogen that to mix the cooling caused insufficient; also other forms of heat exchange container can be adopted; as cooling plate, all within protection domain of the present utility model.
In the utility model embodiment, cooling tube 2 can be arranged in tank body 1, improves the efficiency of heat exchange, makes heat exchanging process no longer pass through other media.The two ends of cooling tube 2 are all connected with the external world of tank body 1, and namely the inwall of cooling tube 2 can not contact with the LNG Liquefied natural gas in tank body 1.One end of cooling tube 2 connects the cryogen outlet of refrigerator 3, and the other end of cooling tube 2 connects the cryogen import of refrigerator 3.Also cooling tube 2 can be arranged tank body 1 outer and be wound around tank body 1, cryogen carries out heat exchange, by cooling tube 2 and tank body 1 also within protection domain of the present utility model with LNG Liquefied natural gas.
In the storage tank that the utility model embodiment provides, cooling tube 2 has multiple set-up mode.Can obtain thus, make cooling tube 2 undulate be arranged in tank body 1, crest and trough are respectively towards the two ends of tank body 1.This setup can strengthen film-cooled heat and Homogeneous cooling, improves the efficiency of cooling.In order to realize above-mentioned technique effect, also can adopt other set-up modes, as made cooling tube 2 helical arrangement near inner tank wall, all within protection domain of the present utility model.
In the storage tank that the utility model embodiment provides, cooling tube 2 can be arranged on multiple position, in order to play better cooling effect, cooling tube 2 can be arranged at the bottom of tank body 1 inside, directly contact with the LNG Liquefied natural gas of tank inside, cooled LNG Liquefied natural gas and uncooled LNG Liquefied natural gas can be made to carry out sufficient heat exchange, make cooling more abundant.Also cooling tube 2 can be arranged at other positions, in the middle part of tank body 1, as long as the cooling of LNG Liquefied natural gas can be ensured, all within protection domain of the present utility model.
In the using process of gas station, environmental factor is in constantly change, and the pressure therefore in tank body 1 is also constantly change, in order to the pressure in Real-Time Monitoring tank body 1, can draw a pressure inlet tube from the inner chamber of tank body 1, and pressure inlet tube connects mechanical pressure gauge 4.Can pressure in Real-Time Monitoring tank body 1 by mechanical pressure gauge 4.Also mechanical pressure gauge 4 can not be used, as the pressure that whether can be above standard by the pressure in ambient temperature and gas station benefit estimation tank body 1, as long as the situation that tank body 1 internal pressure raises can be estimated in advance, all within protection domain of the present utility model.
Because environmental factor change is complicated, the pressure in tank body 1 changes and is not easy to estimate, can obtain thus, the storage tank that the utility model embodiment provides installs pressure transducer 5 additional.A pressure inlet tube is drawn, pressure inlet tube Bonding pressure sensor 5 from the inner chamber of tank body 1.When pressure transducer 5 monitor tank body 1 internal pressure be above standard pressure time, pressure transducer 5 can automatic control electric source switch, starts refrigerator 3, realizes the cooling to the LNG Liquefied natural gas in tank body 1.When being cooled to safety pressure, being monitored by pressure transducer 5, closing refrigerator 3.Make pressure drop in tank body 1 to safety pressure by the way, and ensure constant pressure.Owing to passing through pressure transducer 5 monitoring pressure, automatically starting or closedown refrigerator 3, make cooling procedure more accurate, reduce human error.When not using pressure transducer 5, as long as normal startup and the closedown of refrigerator 3 can be ensured, all within protection domain of the present utility model.
Except above-mentioned storage tank, embodiment of the present utility model also provides a kind of gas station comprising above-mentioned storage tank, and the structure of these other each several parts of gas station please refer to prior art, repeats no more herein.
Above gas station provided by the utility model and storage tank thereof are described in detail.Apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
