Equipment for testing gas adsorbing or desorbing rate

Abstract

The invention provides equipment for testing the gas adsorbing or desorbing rate. The equipment comprises a gas storage tank, a heating furnace, a connecting pipe and a base, wherein the heating furnace is fixedly arranged on a second bracket, the heating furnace is hollow and is internally provided with a reaction tank, one end of the reaction tank is sealed by virtue of a sealing piece while the other end of the reaction tank is connected with the connecting pipe, and a reactor is arranged at one end of the sealing piece, close to the reaction tank and the reactor is arranged in the reaction tank; the base is fixedly arranged on a first bracket, the gas storage tank is installed on the base, the base is internally provided with a gas pipeline, a gas inlet-out valve is arranged at one end of the gas pipeline while the other end of the gas pipeline is connected with the connecting pipe, and the connecting pipe is provided with a safety valve, a plurality of control valves are arranged on the side edge of the gas pipeline, a pressure gauge is fixedly arranged on one side of the connecting pipe, and a thermocouple is fixedly arranged on the other side of the connecting pipe. The equipment for testing provided by the invention is simple in structure and can be used for quickly testing the adsorbing or desorbing rate of gas in a liquid or a solid.

Description

technical field [0001] The invention relates to a device for testing gas adsorption or desorption rate. Background technique [0002] During the manufacturing process of hydrogen storage alloy powder, hydrogen will be adsorbed or desorbed in solid powder, and the adsorption rate or desorption rate of gas in solid powder can be used to evaluate the grade or quality of hydrogen storage alloy powder. At present, the test method of the adsorption rate or desorption rate of gas in solid is generally carried out by using a small amount of solid under sufficient gas source conditions. The solid needs to be ground very uniformly and finely. The test conditions are relatively strict, and the requirements for experimental instruments are also relatively Precise, this method is more complicated to operate and requires higher requirements. Contents of the invention [0003] The invention aims to provide a device for testing gas adsorption or desorption rate with simple structure and ...
