Multifunctional testing system for suppressing explosion of flammable gas by water mist and testing method implementing same

Abstract

The invention relates to a multifunctional testing system for suppressing explosion of flammable gas by water mist and a testing method implementing the same. The multifunctional testing system is structurally characterized by comprising a device main part, a data acquisition part and an accessory part. The device main part comprises a testing pipeline, a seal head and ignition device, a rupture disk clamp and rupture disks. The data acquisition part comprises a pressure sensor, a temperature sensor, a flame sensor, a data acquisition instrument and bundled software. The accessory part mainly comprises connecting pipelines, valves and safety accessories. The testing operation method includes steps of experiment preparation, distribution premixing, explosion suppression testing, and purging and washing, The testing system is convenient to mount, flexible to combine and simple to operate. Preparation of level flammable mixed gas in various concentrations is achieved by a differential pressure distribution method; and various explosion parameters at different situations in explosion suppression process are acquired and recorded by matching with the various sensors. The defects that an existing device is single in function, complex to operate, narrow in suitability and the like are overcome. The multifunctional testing system and the testing method are widely applicable to tests for explosion suppression effects of water-based suppressant and analysis researches.

Description

technical field [0001] The invention relates to a multifunctional fine water mist suppression combustible gas explosion test system and a test method. The invention belongs to the technical field of gas explosion suppression testing. Background technique [0002] Combustible gases are common hazardous chemicals in industrial production processes, and are generally stored and transported in closed containers or pipelines. Due to the limitation of space, after the gas is mixed with air or other combustion-supporting gases and ignited under restricted conditions, a sharp pressure rise rate and a high explosion pressure will often occur, resulting in serious accident consequences. Explosion suppression technology is an effective means to suppress the explosion before the explosion may occur or when the explosion occurs. At present, the existing research directions of explosion suppression technology mainly include solid powder explosion suppression materials, metal porous expl...

AI Technical Summary

Problems solved by technology

First of all, the two systems have high requirements on the corresponding equipment manufacturing and operation level; second, the equipment structure of the two systems is single, and cannot be combined and replaced flexibly; Rough method, narrow application area, lack of flexibility

At the same time, the operation of the existing system involves too many steps, so the overall test process is more likely to be affected, and the accuracy of the test results is prone to deviation
