Gas combustion explosion process in pipeline is a complicated low calorific value and high.Flame in pipeline also exists acceleration communication process, thus causes the generation of pressure wave, and pressure wave can act on flame transmission process in turn.Spark arrester is as the safety equipment stoping flame to be propagated, and back-fire relief speed, explosion arrestment pressure are its main technical parameters.
Spark arrester is the safety device stoping flame to be propagated to source under the fortuitous event such as breaking out of fire during plant running and setting off an explosion.It is widely used in the systems such as storage tank, pipeline, air draft, torch；As last one safety curtain stoping disaster to occur, the Fire resistances of its product is most important.
Utility model content
The purpose of this utility model is the effective foundation in order to form the qualified judgement of spark arrester product, and spy provides a kind of spark plug flame test system.
This utility model provides a kind of spark plug flame test system, it is characterized in that: described spark plug flame test system includes: computer, data acquisition control system, air distribution system, ignition system, gas sampling system, test pipe, test the speed flame sensor, pressure transducer, spark arrester, flame sensor；
Wherein: the centre of test pipe is provided with spark arrester, test pipe part is on the right side of spark arrester for protecting test portion, side, and test pipe part is igniting test portion, side in the left side of spark arrester；
Igniting has been sequentially arranged air distribution system, ignition system in test portion, side from left to right, test the speed flame sensor and pressure transducer, air distribution system, ignition system, tests the speed flame sensor and pressure transducer is connected with data acquisition control system respectively；In test portion, protection side on test pipe, flame sensor and gas sampling system, flame sensor and gas sampling system are installed to be connected with data acquisition control system respectively；Data acquisition control system is connected with computer.
Described test pipe is φ 108 seamless steel pipe.
Described spark arrester is the II A level corrugated plate dst pipeline detonation type spark arrester of nominal diameter 100mm.
Test portion, protection side on described test pipe and igniting test portion, side, length is equal.
When flame is propagated in slit or narrow and small passage, if the spacing of slit or channel diameter are sufficiently small, flame propagate wherein after a segment distance will automatic distinguishing, this phenomenon is referred to as extinguishing.Corrugated plate fire arrestor utilizes this principle to realize back-fire relief function exactly, and the Fire resistances of actual spark arrester product is difficult to be obtained by computational methods, is all to be obtained by use experience and test method.
