Description

technical field [0001] The invention relates to the technical field of detection instruments, in particular to a Claus desulfurization over-control on-line measurement gas swirl defogging device. Background technique [0002] for any set of H 2 S / SO 2 For online analyzers, one of the key points of control is to prevent sulfur (mainly liquid and gaseous) in the sample gas from condensing in the pipeline and monitoring pool, affecting equipment operation and gas monitoring, and increasing engineering maintenance and measurement costs. [0003] In order to solve the influence of liquid sulfur in the tail gas on the measurement, the current sampling desulfurization device mainly adopts two methods: one is cold desulfurization, and the other is thermal desulfurization. Among them, the basic principle of thermal desulfurization is: the whole process of heat tracing is adopted, and high-temperature heat tracing is carried out from sample gas sampling to discharge back to the proc...
