Abstract

The present invention relates to a minimum ignition energy test system and method for combustible gas explosion at ultra-low temperature. The test system includes a vacuum pumping system, a gas distribution system, a refrigeration system, an integral circuit ignition system and a data acquisition system. An explosion container is installed in the refrigeration system , the vacuum system communicates with the explosion vessel through the connecting pipeline of the gas distribution system, and the gas distribution system communicates with the interior of the explosion vessel through the connecting pipeline; the integral ignition system includes an ignition energy test bench, an ignition electrode located in the explosion vessel, a The probe and current transformer, the ignition energy test bench are connected to the ignition electrode, the high-voltage probe and the current transformer are respectively connected to the ignition energy test bench and the ignition electrode; the data acquisition system includes a data collector and is connected to the data collector and installed on Pressure sensor and temperature sensor inside the explosion vessel. The test system of the present invention has high safety performance and accurate test performance, and can accurately test the minimum ignition energy of combustible gas explosion at ultra-low temperature and high pressure, and the measured data is of great significance for guiding the safe production of the oxygen-containing coalbed methane liquefaction process.

Description

technical field [0001] The invention belongs to the technical field of industrial production safety, and in particular relates to a test system and method for researching the minimum ignition energy characteristics of combustible gas explosions in an ultra-low temperature environment. Background technique [0002] The deoxidation of coalbed methane is a technical problem at home and abroad. At present, the main deoxygenation technologies include adsorption method, membrane separation method, combustion deoxygenation method and low temperature separation method. Among them, the low-temperature separation method removes impurities completely and the product has high purity, so it is a more commonly used method. Existing research results show that the most dangerous part of the whole coalbed methane low temperature working condition is the fractionation stage (temperature -160~-170℃, pressure 0.1~0.3MPa), especially at the top of the fractionation tower, where the methane conc...
