Abstract

The invention discloses a sulfur measuring system, comprising a combustion tube (3), a drying tube assembly (5) filled with a magnesium perchlorate drying agent and a pre-dewatering device (4) arranged between the combustion tube (3) and the drying tube assembly (5), wherein the pre-dewatering device (4) comprises a nafion tube (41) and a shell (42) covering outside the nafion tube (41), the nafion tube (41) is connected between the outlet end of the combustion tube (3) and the air inlet end of the drying tube assembly (5), and the shell (42) is provided with an exhaust port and an air inlet for introducing dry gas. According to the sulfur measuring system, the nafion tube is used in the pre-dewatering device, and the nafion material is only used for bringing away internal moisture through external drying, so that the moisture flowing into the drying tube assembly is effectively reduced, the failure frequency of the magnesium perchlorate drying agent in the drying tube assembly is reduced, and the test cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of testing systems, in particular to a sulfur measuring system. Background technique

[0002] At present, the main method for testing the sulfur content in substances is infrared flow measurement. The test sample is burned at high temperature to generate sulfur dioxide, which is then sent to the infrared detection cell for detection.

[0003] However, the test sample will also produce water vapor during the combustion process, and the water vapor will react with sulfur dioxide to generate sulfurous acid after condensation, which will affect the accuracy of the test results.

[0004] Therefore, in order to remove the water vapor in the combustion gas, the gas generated after burning the test sample is passed into the drying tube assembly equipped with magnesium perchlorate, dried and then passed into the infrared detection cell for detection. However, the magnesium perchlorate desiccant will fail after abso...
