Description

LNG storage tank stirring apparatus
Technical field
The utility model relates to LNG storage tank technical field, especially LNG storage tank stirring apparatus.
Background technique
Along with extensive use and the develop rapidly of domestic LNG, the technology of LNG gas station and application are also at high speed development.In LNG transportation process or storage process, at any time the passing of time, stratification can appear in the LNG in the LNG storage tank, causes LNG to form a gradient density, and near-bottom temperature is low, upper strata temperature height, the gasification of LNG is accelerated, caused the pressure in the LNG storage tank to rise, adopt the interior BOG gas of blowdown vessel to come the regulating tank internal pressure usually, perhaps by spraying to reduce a jar internal pressure, the former can cause the pollution of environment and the waste of LNG resource like this; The latter's inefficiency also can cause the bigger waste of aspects such as electric energy and manpower simultaneously.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of LNG storage tank stirring apparatus is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of LNG storage tank stirring apparatus, comprise the LNG storage tank, stirring system and drive system, described LNG tank top is provided with pressure transducer, described LNG storage tank middle part is provided with the density sensing system, described stirring system comprises the driving steel pole, impeller and pedestal, described driving steel pole is arranged in the impeller center, and fixedly connected with impeller, described pedestal is fixed on the LNG reservoir walls, described driving steel pole two ends are rotationally connected with on the pedestal, described drive system comprises motor, electromagnetic block and motor cabinet, described drive system is fixedly connected on LNG storage tank outside by motor cabinet, corresponding with pedestal, described motor is fixedly connected on the motor cabinet, described electromagnetic block is fixedlyed connected with machine shaft, and described drive system is connected with pressure sensor signal, and described drive system is connected with the density sensor signal.
Particularly, described LNG storage tank is provided with solar electric power supply system outward.
Particularly, described solar electric power supply system is connected with the drive motor circuit.
Particularly, described some magnetic patch central shaft overlaps with driving steel pole central shaft.
The beneficial effects of the utility model are: a kind of LNG storage tank stirring apparatus that the utility model provides can reduce the pressure of LNG storage tank fast by the method for magnetic agitation, make the uniformity of temperature profile in the LNG storage tank, effectively prevented because of in the LNG storage tank because of density unevenness cause the rolling, install simple, energy-conservation, high working efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is LNG storage tank stirring apparatus schematic representation of the present utility model;
Fig. 2 is the partial enlarged drawing of " A " position among Fig. 1;
