Abstract

The invention discloses a method for measuring the liquid level of molten sulfur. The method comprises the following steps: measuring the weight of a sulfur melting tank, the total weight of the molten sulfur and the sulfur melting tank, the melting temperature of the molten sulfur in the sulfur melting tank; , to obtain the corresponding density correction coefficient value and the density of molten sulfur at the temperature; for the obtained molten sulfur and the total weight and density of the molten sulfur tank, obtain the liquid level of molten sulfur. In the method of the invention, by weighing and measuring the melting temperature, the liquid level value of the molten sulfur can be obtained according to the linear regression equation of the weight of solid sulfur, the density of the molten sulfur and the liquid level of the molten sulfur, and has the advantages of simple operation, strong practicability, It has the advantages of high measurement efficiency, high measurement accuracy, and little influence from external factors. The relative error between the detected value and the actual measured value is within 5%, which solves the problems of inaccurate measurement and large fluctuations affected by working conditions of conventional radar level gauges. , has a high use value and a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of chemical production and relates to a method for measuring the liquid level of molten sulfur. Background technique [0002] At present, the instruments and methods for measuring sulfur level include float level gauge, radar level gauge, and connecting pipe with steam jacket. For example, on the radar measurement window, the liquid surface may be solid, liquid or solid-liquid mixed state, and there may be an unmelted state locally, resulting in inaccurate liquid level measurement; the tank contains various vapors evaporated, which are corrosive to a certain extent and affect The measurement accuracy of the radar level gauge fluctuates greatly. Self-made float level gauge, the float is easy to get stuck, resulting in measurement failure. Even connecting pipes with steam jackets are prone to frequent blockages and require manual dredging, which brings difficulties to liquid level monitoring. Patent CN20182...
