Abstract

The invention discloses experimental testing equipment for the mixed gas adsorption capacity of coal rock / shale. The experimental testing equipment is characterized in that a first gas storage cylinder (1) and a second gas storage cylinder (2) are communicated with a gas mixing container (22); the gas mixing container (22) is communicated with a reference tank (28) and a sample tank (29) in sequence through a gas storage tank (16); a first electromagnetic valve (5) and a first electromagnetic flowmeter (7) are arranged between the gas storage cylinder (1) and the gas mixing container (22); and a second electromagnetic valve (6) and a second electromagnetic flowmeter (8) are arranged between the second gas storage cylinder (2) and the gas mixing container (22).

Description

technical field [0001] The invention relates to an experimental test device for the adsorption capacity of mixed gas in coal rock / shale. Background technique [0002] The experimental equipment for testing the adsorption of gas in coal rock or shale is mainly the isothermal adsorption instrument, which mainly tests the adsorption amount of pure gas in coal rock or shale. At present, there is no experimental test device for the integration of the mixed gas distribution system and the adsorption system. To test the adsorption capacity of the mixed gas in coal rock or shale, it is necessary to prepare the mixed gas separately, and then use the isothermal adsorption instrument to test the adsorption capacity. Such a test method cannot change the concentration ratio of the mixed gas at any time according to the experimental requirements, but can only prepare the gas in advance according to the predetermined concentration ratio, thus bringing about no change in operation. At the...
