摘要
文章结合企业实际,深入分析工艺装置的运行状况和存在的问题,按照"安全、可靠、经济、实用"的原则,设计了一套甲醛生产系统的自动化及安全联锁系统方案。阐述该系统的工艺流程、系统方案、硬件配置、系统安全控制功能等。该系统安全联锁项目内容主要有蒸发氧化和吸收工艺过程。实施后的控制系统技术先进、安全等级高、质量可靠、操作方便,生产效率大幅度提高。
The paper links to the enterprise reality, thorough analysis craft installment movement condition and existence question. According to ＂safe, reliable, economical, practical＂ the principle, we have designed an automation and safety interlocking system solution of formaldehyde production. Described the system＇s processes, rehabilitation programs, hardware configuration, system security control functions and so on. The system safety interlock project mainly includes evaporation oxidation and absorption. After transformation, the control system has an advanced technology, a high level of security, reliable quality, convenient operation, substantial increase in production efficiency.
