Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
To shown in Figure 6, a kind of integrated form LNG skid aerator comprises low-temperature storage tank body 1 as Fig. 1, and described low-temperature storage tank body 1 one ends offer liquid outlet 2, evenly are provided with some radiating fin 3 in the described low-temperature storage tank body 1.
Described radiating fin 3 adopts a kind of in titanium alloy radiating fin, nickel alloy radiating fin, silver alloy radiating fin, aluminum alloy heat sink, magnesium alloy radiating fin, the copper alloy heatsink.It is better that the radiating fin 3 that these materials make passes warm radiating effect.
Described low-temperature storage tank body 1 one sides are provided with some bleed valves, and the BOG gas that needs in the low-temperature storage tank body 1 to discharge is discharged by bleed valve.
Described low-temperature storage tank body 1 is provided with pressure alarm, can in time report to the police to the pressure in the low-temperature storage tank body 1, reminds the staff manually to diffuse BOG gas, has improved Security.
Since in the low-temperature storage tank body 1 up and down the LNG liquid at two ends and low-temperature storage tank body 1 center have the temperature difference, therefore, as shown in Figure 2, described radiating fin 3 is and laterally is evenly arranged in the low-temperature storage tank body 1.Radiating fin 3 is separated into a plurality of compartments with low-temperature storage tank body 1 from top to down, these compartments can to gas phase in the low-temperature storage tank body 1 and liquid phase not the equality of temperature interlayer carry out fast and automatically, balance, the balanced temperature that passes, and rapid most heat absorption that the LNG of higher temperature is discharged, the local higher temperature of LNG liquid is promptly dispersed, make the pressure in the low-temperature storage tank body 1 be effectively controlled, thereby stoped evaporation and the discharge of BOG.
Because there is the temperature difference in the LNG liquid at two ends, the left and right sides and low-temperature storage tank body 1 center in the low-temperature storage tank body 1, therefore, as shown in Figure 3, described radiating fin 3 is and vertically is evenly arranged in the low-temperature storage tank body 1, radiating fin 3 is separated into a plurality of compartments with low-temperature storage tank body 1 from left to right, these compartments can to gas phase in the low-temperature storage tank body 1 and liquid phase not the equality of temperature interlayer carry out fast, automatically, balance, the balanced temperature that passes, and rapid most heat absorption that the LNG of higher temperature is discharged, the local higher temperature of LNG liquid is promptly dispersed, make the pressure in the low-temperature storage tank body 1 be effectively controlled, thereby stoped evaporation and the discharge of BOG.
Pass temperature in order to improve better, radiating effect, as shown in Figure 4, described radiating fin 3 is horizontal and vertical and is arranged alternately in the low-temperature storage tank body 1, radiating fin 3 is separated into a plurality of little compartments with low-temperature storage tank body 1, these little compartments can to gas phase in the low-temperature storage tank body 1 and liquid phase not the equality of temperature interlayer carry out fast, automatically, balance, the balanced temperature that passes, and rapid most heat absorption that the LNG of higher temperature is discharged, the local higher temperature of LNG liquid is promptly dispersed, pass temperature, radiating effect is more uniform and stable, reduce the pressure in the low-temperature storage tank body 1 widely, stoped evaporation and the discharge of BOG.
In order to reach more uniform biography temperature, radiating effect, as shown in Figure 5, be rotating center with radiating fin 3 symmetry center, described some radiating fin 3 Rotating with Uniform are distributed in the low-temperature storage tank body 1.
In addition, as shown in Figure 6, described radiating fin 3 also can be the arc radiating fin, and the arc radiating fin is compared with rectilinear radiating fin, and biography is warm, radiating effect is better.
Compared with prior art, integrated form LNG skid aerator of the present invention is simple in structure, easy to use, temperature minimum reaching-196 in the low-temperature storage tank body 1 ℃, the gas phase of local higher temperature in jar, the fluid temperature that the external environment condition of tank skin edge higher temperature is leaked the heat place all reduces greatly, especially when the new LNG liquid of unloading is gone into jar, make in the jar, the LNG of different temperatures reaches uniform temp rapidly in the tank car, the degrees of expansion of gas greatly reduces, the pressure of container sharply descends, and the high temperature gas phase is delivered to low temperature liquid phase fast in the storage tank to have fabulous can finishing automatically in moment, liquidus temperature transmits fast between different liquid levels and reaches balance, balanced performance.
Be enlightenment with above-mentioned foundation desirable embodiment of the present invention, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
