一、系统简介 在练焦过程中,将生产大量一氧化碳和其它挥发性气体,对它们虽然可以进行精制提取副产品。但是,如果压力过高或有泄漏,就会造成重大危害。上海宝钢二期焦炉煤气放散点火控制系统就是根据冶金部鞍山焦耐院关于焦化厂、煤气厂环境保护、消防、安全卫生设计技术规定(JNB002-90)的要求设计的。整个系统由可编程序控制器PC-110、放散阀GOM610LM、电子调节器EKC-211A、显示仪表KMH等设备组成。系统示意图如图1所示。 First, the system profile In the process of coke, will produce large amounts of carbon monoxide and other volatile gases, although they can be purified by-products. However, if the pressure is too high or there is a leak, it will cause serious harm. Shanghai Baosteel II coke oven gas emission ignition control system is based on the Ministry of Metallurgical Anshan Jiao Na hospital on the coking plant, gas plant environmental protection, fire safety and health and hygiene design and technical requirements (JNB002-90) requirements. The entire system consists of programmable logic controller PC-110, drain valve GOM610LM, electronic regulator EKC-211A, display instruments KMH and other components. System diagram shown in Figure 1.
