Visualized combustible material explosive chemical chain reaction process testing device and method thereof

Abstract

The invention discloses a visualized combustible material explosive chemical chain reaction process testing device and a method thereof. The device includes an explosion flame shooting system, a freeradical test system, an ignition system, a circulating water cooling system, a temperature control and thermal insulation system, a pressure control and monitoring system, a data acquisition system, amaster control system, an explosion gas rapid sampling system, a secondary pulsation atomization gas and liquid distributing system, a solid powder injection system and a spherical shell. Therefore,the shooting of explosion flame, the testing of explosion intermediate products and the rapid sampling and analysis of explosion gas can be realized; and through the coordination effects of the systems, and through the contrast and analysis before and after explosion reaction and the changing situations such as the explosion flame, reaction temperature, reaction pressure, explosive intermediate product free radicals and the explosion gas during processes, mechanisms and characteristics of combustible material explosion chemical chain reaction processes can be qualitatively and quantitatively studied, so that more comprehensive experimental data and information can be provided for researchers.
