Peripheral test instrument comprises: reduction valve and the flowmeter of the intercommunication that is connected with air intake opening pipeline, the pressure tester of the intercommunication that is connected with pressure tap, drying agent and the hydrogen analyser of the intercommunication that is connected with survey concentration point, the thermocouple temperature measuring apparatus of the intercommunication that is connected with point for measuring temperature.
Its workflow is: first in casing, assemble catalyzer dehydrogenation unit by experiment demand, seal case, then the hydrogen configuring is connected with reduction valve with the mixed gas of air, after flowmeter, entering inner wall belt has the air intake opening pipeline of spiral fan to go forward side by side in gas distributor, mixed gas flows out and turns back upwards from the spout of gas distributor, through recording one group of empirical value by pressure measurement force and survey concentration point before catalyzer dehydrogenation unit, the mixed gas catalyzer dehydrogenation unit of flowing through, oxyhydrogen reaction heat release, the thermocouple assembly of casing both sides records the temperature of each locus between catalyst-assembly, mixed gas by catalyzer dehydrogenation unit after side pressure force by upper end and survey concentration point and record group reaction data, finally by distribution pipeline, discharge on gas outlet pipe road,
If experiment has humidity requirement, inject a certain amount of aqueous solution by water supplement port, make the spout of liquid level higher than gas distributor.While having soda acid requirement, also can allocate a certain amount of acidity or alkaline solution into.Mixed gas by turning back out in solution, can be brought acid/aqueous slkali into experimental enviroment after spout.After test, to clean in time bottom half.
Casing of the present invention adopts three stage structure, is convenient to dismounting and lays catalyzer dehydrogenation unit, and be convenient to process the cleaning after experiment; Bottom half has water supplement port, can experimental different demand filling liquids, solve the multiple nuclear power station operating condition such as air and steam atmosphere under dry air atmosphere, air and water vapor mixed atmosphere, acidity and alkali condition and the simulation of post accident environment.In the design of this flow process, the resistance running into when the catalyzer in order to reduce gas flow reserves space so that air-flow passes through between catalyzer dehydrogenation unit.The present invention has realized under above several conditions simultaneously, the test of the performance to aspects such as catalyzer high temperature resistance high humidity, soda acids.
