Disclosed are a combustible gas explosion simulation test device and method for a high-voltage electrostatic precipitator, the device comprising: an explosion-proof cabinet (1); an anode cylinder (2) simulating the anode of the precipitator; a cathode rod (3) simulating the cathode of the precipitator; The conductive rod (4) for hanging the cathode rod (3); the insulator (5) for fixing the conductive rod (4); the pulse capacitor (6) for simulating the electrode capacitance of the dust collector; the connecting pulse capacitor (6) and the conductive rod (4) A high-voltage cable (7); a mica tube (8) for protecting the high-voltage cable (7); an intake unit for feeding combustible gas into the anode cylinder (2) of the explosion-proof cabinet; a pressure sensor (10) for measuring the explosion pressure; and observing the explosion Phenomenal cameras (11). Using the device to carry out a high-voltage electrostatic precipitator combustible gas explosion simulation test can simulate the process of the combustible gas explosion inside the precipitator caused by the spark discharge of the precipitator, and measure the characteristic quantities of the spark discharge and gas explosion, which has high safety.

Description

Technical field [0001] The present invention relates to the field of electrostatic precipitator spark discharge, in particular to the high-pressure electrostatic precipitator combustible gas explosion simulation test apparatus and method. Background [0002] High-voltage electrostatic precipitator is a commonly used dust removal method in factories at present, which has the advantages of high dust removal efficiency and low energy consumption. When performing high-pressure electrostatic precipitator removal for combustible gases such as coke oven gas, if the oxygen content in the gas exceeds the standard, once a spark discharge occurs in the dust removal electrode, it may lead to gas combustion and damage to the dust collector, and even lead to a serious explosion accident. [0003] At present, for the explosion prevention of combustible gases through high-pressure electrostatic precipitator, on the one hand, the oxygen content monitoring device is set up in the intake part of th...
