Abstract

The invention discloses a slope adjustable and underlying surface adjustable small-scale flowing fire simulation experiment device and method. The device comprises a flowing groove system, an oil supply system, an overflowing oil collection system and a data acquisition system, wherein the flowing groove system comprises a rectangular flowing groove, an underlying surface, a lifting table, a supporting table, a flowing stabilizing device and an optical leveling device, the oil supply system comprises a peristaltic pump, a hose and an oil supply barrel, the overflowing oil collection system comprises an oil outlet pipe and an oil collecting barrel, and the data acquisition system comprises a thermocouple array, a first camera, a second camera, a thermal infrared imager, an electronic balance, a data conversion module and a computer. According to the invention, parameters such as spreading distance, spreading rate, temperature, flame height and the like of flowing fire can be studied, sothat the influence mechanism of bottom surface gradient and underlying surface heat loss on fire spreading speed characteristics can be studied, and favorable basis and support are provided for emergency treatment of flowing fire accidents.

Description

technical field [0001] The invention relates to the intersecting field of materials and safety, and more specifically relates to a flow fire simulation experiment device and method under the environment of variable slope and variable underlying surface material environment. Background technique [0002] In the production, storage, transportation and use of petrochemical industry, liquid fuel leakage accidents occur from time to time. If it is ignited by an open flame, it will form an oil spill fire. Flowing fire is a dynamic development process, which will connect the surrounding tanks and equipment into a whole, so that both equipment and personnel will suffer great threats. At the same time, the flowing fire spreads rapidly and affects a large area, which greatly increases the difficulty of rescue. According to the difference in the fuel liquid leakage environment, the spreading behavior of flowing fire may occur under different slopes and different thermal and physical ...
