Analysis and processing arrange, electrode type (such as flange electrode), material and size, gap distance, spark duration and breakdown
The influence of voltage and these minimum ignition energies.
1. Source Type of lighting a fire
The incendiary source is that there are two the spark ignition sources of electrode for band.
2. installing
Igniting occurs in the bottom of pipe, therefore electrode is fixed on the opposite direction of axis, on the upper surface in commutative hole
At 5mm~10mm.
(12) gas expansion tank 12
The expansion drum being connected between gas handling system and the outlet end of pipe, to simulate constant pressure exaggerated conditions.Extraction fan
Combustion product discharge in pipe is arrived into absorbing liquid by gas expansion tank, then remaining clean gas is arranged by exhaust outlet
Out.
(13) there is the collecting tank 13 for neutralizing solution
The combustion product of previous trial should be all thoroughly removed after test every time, and guarantees that combustion product will not be to work people
Member and environment generate adverse effect.Therefore suitable vent gas treatment mode should be selected, burnt especially for halogenated hydrocarbons
After can generate hydrogen fluoride or hydrogen chloride etc., should be neutralized as early as possible, reduce corrosion to instrument and equipment.
(14) material requirement: all components of all component, link member and experimental bench should resistance to gas attack, such as
Ammonia and copper can react, and other oxidation reactions etc..Stainless steel or other corrosion-resistant materials can be used.
