在工业生产中,气体二氧化硫浓度的连续自动测定具有相当大的意义,它不仅在硫酸工业,而且在冶炼工业以及其他许多有关的生产过程中都是需要解决的问题。为此,我们研制了二氧化硫连续自动分析器。该仪器的特点是结构简单,成本很低,操作维护方便,而且测定范围广(从0.1％～15％),干扰气体少,仪器的使用具有一定的普遍性。结构和原理
In industrial production, the continuous and automatic determination of the concentration of sulfur dioxide in a gas is of considerable significance. It is a problem that needs to be solved not only in the sulfuric acid industry but also in the smelting industry and many other related production processes. To this end, we developed a continuous sulfur dioxide analyzer. The instrument is characterized by simple structure, low cost, easy operation and maintenance, and a wide range of measurement (from 0.1% to 15%), less interference gas, the use of the instrument has a certain degree of universality.
