Abstract

The invention provides a multifunctional experiment apparatus used for an emergent relief experiment research during runaway reaction. The whole process simulation of the runaway reaction is carried out, therefore useful data is provided for engineering design and type selecting of a safe relief apparatus, and essential data is provided for reactivity hazard assessment. The simulation experiment device comprises a reaction kettle, a pressure bearing kettle, a charging system, a relief control system, a temperature-control system, a pressure control system, a relief collection treatment system, a data acquisition and storage system, an automatic operation and control system and safe subsidiary facilities. The simulation experiment device has the advantages of novel structure design, strong function, convenient experiment, less time consumption and large reactant dosage; the invention employs pressure tracking and temperature tracking technology for realizing adiabatic heat metering test, the thermal inertia is small, the measured experiment data can be directly used in engineering, the whole process simulation of the runaway reaction is carried out, the useful data is provided for reactivity hazard assessment and emergent relief apparatus design.

Description

technical field [0001] The present invention relates to a simulation experiment device for emergency release of uncontrolled chemical reaction in petrochemical industry, in particular to design and type selection of safety release devices such as safety valves and burst discs used for chemical reaction risk assessment and testing of petrochemical devices The required basic experimental data and the simulation experimental device for simulating the emergency release process when an out-of-control reaction occurs. Background technique [0002] Safety relief means that once overpressure occurs in the closed pressure equipment, the emergency relief device of the equipment will be opened automatically, so as to avoid unbearable explosion pressure inside the equipment. The uncontrolled chemical reaction is one of the important reasons for the overpressure of the equipment. If the design of the emergency relief device is unreasonable, the overpressure of the equipment will be damag...
