LNG leakage water curtain inhibition experiment method

Abstract

The invention relates to an LNG leakage water curtain inhibition experiment method which aims at mainly solving the problem of the blank of the LNG leakage water curtain inhibition experiment method in the prior art. According to the technical scheme adopted by the invention for well solving the problem, due to the adoption of the LNG leakage water curtain inhibition experiment method, LNG leakage water curtain inhibition experiment is implemented by virtue of an LNG leakage water curtain inhibition experiment device; the experiment method comprises the following steps: (1) guiding LNG in an LNG storage tank into a leakage tank; (2) opening a leakage nozzle and spraying the LNG out of the leakage nozzle; (3) starting a data acquisition system, carrying out data acquisition and recording image; (4) starting a water curtain system, spraying water out of a water curtain nozzle to form a water curtain, and carrying out data acquisition by virtue of the data acquisition system and recording the image; and (5) sequentially closing the leakage system, the water curtain system and the data acquisition system after the data collected by a monitoring point array is stable so as to end the experiment. The method can be applied to the LNG leakage water curtain inhibition experiment.

Description

technical field [0001] The invention relates to an experimental method for suppressing an LNG leakage water curtain. Background technique [0002] As a clean and efficient energy source, liquefied natural gas (LNG) has been widely used in industry and civil use in recent years, and has become one of the fastest growing energy sources. LNG has dangerous characteristics such as ultra-low temperature, flammability and explosion. Once a leak occurs, the low-temperature LNG vapor will spread along the surface. If it encounters an ignition source, it may cause catastrophic consequences such as fire and explosion. How to restrain the scope of influence of LNG leakage and spread, reduce its harmful consequences, so as to realize the control of the risk of its leakage and spread has become one of the key issues to ensure the safety of LNG. [0003] At present, water curtain is the most economical and effective technology to deal with LNG leakage. CN 203202588 U relates to a water c...
