[0002] Sulfur in coal is a harmful element, and high-sulfur coal will cause great harm when burned, gasified or coked. For example, when high-sulfur coal is used as fuel, the sulfur dioxide gas generated after combustion will not only seriously corrode the boiler pipes, but also seriously pollute the atmosphere; in addition, the sulfur content also directly affects the calorific value of coal. Therefore, the sulfur content in coal is an important index for coal quality detection.

[0003] In the prior art, when using a coulomb sulfur meter to measure the sulfur content in coal, the coal sample is burned and decomposed in an air stream under the action of a catalyst, and the sulfur in the coal generates sulfur oxides, and then the electrolyte is used to absorb the sulfur oxides generated by combustion, and the total sulfur content in the coal is calculated according to the consumed electric quantity.

[0004] The existing sulfur meters can only complete the sample feeding, chemical analysis, and have a high dependence on manual labor. For example, weighing, adding samples, weighing and adding catalysts, etc. all rely on manual labor, and the degree of automation is low and needs to be improved. Content of the Utility Model
