气体检测的关键结构单元是气敏元件和气体传感器。该文概述了气体传感器的主要类型及其应用范围，根据装置的特点选用电化学传感器，并配置以记录仪和声、光报警器组合成对含氯气体的环境监测报警技术，能保证铂重整装置催化剂再生系统的正常运转。该监测报警技术不仅适用于铂重整装置催化剂再生系统，对其它含氯气体的环境监测报警也具有普遍的实用意义。
The key structural units for gas detection are gas sensors and gas sensors. This paper summarizes the main types of gas sensors and their application range, selects electrochemical sensors according to the characteristics of the device, and configures an environmental monitoring and alarm technology for chlorine-containing gas with a combination of recorder and sound and light alarm to ensure platinum weight The entire device catalyst regeneration system of normal operation. The monitoring and alarming technology is not only applicable to the catalyst regeneration system of the platinum reformer, but also has universal practical significance for environmental monitoring alarms of other chlorine-containing gases.
