Problems solved by technology

The disadvantage of this method is that the evaporation of LNG will be aggravated during the stirring process, and a large amount of BOG will be generated, which has potential safety hazards
In addition, power consumption is required and the operating cost is high

Embodiment Construction

[0025] like figure 1 As shown, the present invention relates to an LNG storage tank rollover suppression device, which mainly includes: an LNG storage tank 1, a heat pipe 2 and a connector 3, the heat pipe 2 is upright in the LNG storage tank 1, and several heat pipes 2 are in the LNG storage tank 1 Evenly arranged, adjacent heat pipes are connected to each other through connectors 3 .

[0026] like figure 2 The heat pipe 2 is a cylindrical body sealed at both ends, made of metal, filled with liquid nitrogen as a working medium after being evacuated into a vacuum, and annular fins 4 are evenly arranged on the pipe wall along the axial direction.

[0027] The heat pipe 2 transfers heat by the phase change of the internal working fluid and steam flow, and the latent heat transfer efficiency of the phase change is much higher than that of convective heat transfer and general heat conduction. The upper part of the heat pipe 2 is the condensing section, and the lower part is the...

Abstract

The invention relates to an LNG storage tank rollover suppression device which mainly comprises an LNG storage tank, heat pipes and connectors, wherein the heat pipes are upright in the LNG storage tank and uniformly arranged in the storage tank; two adjacent heat pipes are connected with each other through the connector. When a temperature gradient exists between liquid layers in the LNG storage tank, the heat pipes are rapidly started, and bottom heat is transferred to the top, so that the temperature in the storage tank is kept basically consistent, and a rollover phenomenon is suppressed from the source. Compared with the prior art, the LNG storage tank rollover suppression device disclosed by the invention has the advantages that the heat pipes are driven to work by virtue of the temperature difference of the liquid layers, and a mechanical motion part is avoided, so external motive power is not needed, the noise interference or pollution is avoided, daily maintenance is not needed, and the device is safe and reliable and can continuously work for a long time.

Description

[0001] Technical field: [0002] The invention relates to the technical field of LNG storage, in particular to a device for suppressing rollover accidents of an LNG storage tank. [0003] Background technique: [0004] Liquefied Natural Gas (Liquefied Natural Gas) is a liquid obtained by cooling purified and compressed natural gas below its boiling point (about -160°C) under normal pressure. Its weight is about 45% of the same volume of water, its volume is about 1 / 600 of the same mass of gaseous natural gas, its density is about 600 times that of methane under standard conditions, and its volumetric energy density is 72% of that of gasoline. Natural gas liquefaction can greatly save storage and transportation space, and has the characteristics of large calorific value and high performance. [0005] There are a certain number and scale of storage tanks in satellite liquefaction stations and LNG receiving stations. During the storage of LNG in the tank, there will be an unstab...
