Abstract

The invention discloses a gas diffusion coefficient measuring device and an operating method thereof, and belongs to the field of experimental devices. The gas diffusion coefficient measuring device is characterized in that: a Stefan diffusion tube is suspended inside a tank body of a thermotank, and a vertical section of the Stefan diffusion tube is provided with scales; a water supply device isused for supplying water to the thermotank; a magnifier is used for observing the scale of the vertical section of the Stefan diffusion tube; a gas supply device is used for supplying gas to the thermotank, and a gas preheater is arranged inside the thermotank; when the gas supply device supplies gas to the thermotank, the gas enters a horizontal section of the Stefan diffusion tube after being preheated by the gas preheater. The gas diffusion coefficient measuring device of the invention can ensure stability of gas flow, reduce error and solve the problems of nonuniform temperature, inaccurate data reading, and large experimental error of a conventional gas diffusion coefficient measuring experiment device. The operating method of the gas diffusion coefficient measuring device disclosed by the invention has the characteristics of simplicity in operation, accuracy in data reading and small test experiment error.

Description

technical field [0001] The invention belongs to the field of experimental devices, and relates to a gas diffusion coefficient measuring device and a working method thereof. Background technique [0002] The temperature of the existing gas diffusion coefficient measurement experimental device is unstable, the main glass water tank is not insulated, and the uneven water temperature requires the assistance of a stirring device, the process is complicated, time-consuming and laborious; The device is only heated locally by the heating rod, and the water temperature is uneven, resulting in large test errors; and there is no scale on the core component Stephen diffusion tube, which leads to errors in reading data; the existence of the above three errors will lead to inaccurate measured diffusion coefficients. precise. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of inaccurate measurement of gas diffusion coefficient due ...
