Abstract

The invention relates to an LNG leakage water curtain restraint experiment device. The LNG leakage water curtain restraint experiment device mainly solves the problem that an LNG leakage water curtain restraint experiment device is not available yet in the prior art. The LNG leakage water curtain restraint experiment device comprises a discharging system, a water curtain system, a data acquisition system and a control system, wherein the discharging system comprises an LNG storage tank, an LNG discharging tank, an inert gas cylinder and a discharging spray head, the water curtain system comprises a water inlet pipeline and a water curtain nozzle, and the data acquisition system comprises a signal processor, a thermocouple, a methane concentration detector, an anemometer, a hygrometer and a high-speed camera. By the adoption of the LNG leakage water curtain restraint experiment device, the problem that LNG leakage water curtain restraint experiment device is not available yet in the prior art is well solved. The LNG leakage water curtain restraint experiment device can be applied to an LNG leakage water curtain restraint experiment.

Description

technical field [0001] The invention relates to a water curtain suppression experimental device for LNG leakage. 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 suppress the scope of influence of LNG leakage and spread, reduce its harmful consequences, so as to control the risk of its leakage and spread, [0003] It has become one of the key issues to ensure the safety of LNG. [0004] At present, water curtain is the most economical and effective technology to deal with LNG leakage. CN 203202588 U relates to a water curtai...
