Abstract

The invention relates to a storage tank implosion multi-field coupling experimental testing device. An igniter sleeve and a plurality of temperature sensor sleeves are arranged on an experimental storage tank of the storage tank implosion multi-field coupling experimental testing device and are the same in structural size, the temperature sensor sleeves are arranged at the tank top and the upper portion, the lower portion and the two sides of the tank wall respectively, an ignition nozzle and the igniter sleeve are detachably connected, and temperature sensors are detachably connected with the corresponding temperature sensor sleeves. A water storage tank, an oxygen cylinder and a combustible cylinder are connected with the experimental storage tank. Each temperature sensor is correspondingly provided with a pressure sensor, two displacement sensors are symmetrically arranged on the tank wall, and a plurality of strain sensors are arranged on the same straight line and the straight line perpendicular to the straight line from the tank top to the lower portion of the tank wall. The temperature sensors, the pressure sensors, the displacement sensors and the strain sensors are connected with a signal collecting system. Gas-liquid-solid three-phase coupling testing is carried out at different detonation point positions in the storage tank.

Description

technical field [0001] The invention relates to an experimental device for storage tank research, in particular to a storage tank implosion multi-field coupling experiment testing device. Background technique [0002] As an important storage equipment, vertical storage tanks are widely used in various industries, especially in the storage of medium in the petroleum and petrochemical industry. Various reaction media, refined oil and crude oil are storage containers of this structure. Because its internal storage medium is extremely volatile and flammable gas, if an accidental factor acts as an "ignition source", it will cause the storage tank to explode. The occurrence of such accidents is mainly due to the combustion and explosion of the internal storage medium, which leads to implosion damage of the storage tank under the action of instantaneous overpressure and temperature rise. The implosion failure of this kind of storage tank structure is a typical multi-field coupling...
