一、概述硫酸工业在国民经济中占有相当重要的地位,在硫酸生产中酸浓度的准确分析控制具有极重大的意义。过去我厂93%H_2SO_4浓度一直依靠落后的人工分析来检测,操作工人每隔半小时取样分析一次,这样不仅劳动强度大,而且分析不准确,指导生产不及时,往往因不能及时反映酸浓度的变化,操作工人实际上是在进行盲目控制,因而操作不平稳,有时出现产品不合格,甚至造成事故停车,严重地影响了产品的质量和产
First, an overview Sulfuric acid industry occupies a very important position in the national economy, sulfuric acid production in the accurate analysis and control of acid concentration is of great significance. In the past, 93% H_2SO_4 concentration in our factory was always detected by backward manual analysis. The workers sampled and analyzed every half hour, which resulted in not only labor intensity but also inaccurate analysis, which led to the production not timely. Change, the operation of workers is actually under the blind control, so the operation is not stable, and sometimes appear unqualified products, or even cause an accident parking, seriously affecting the quality of the product and production
