【摘要】：MCO (MC表示机壳水平剖分结构,O表示单悬臂叶轮)空压机组是通过其自身的压缩级别来控制压缩机出口工艺气体压力的增压装置。MCO空压机组已广泛应用于空分、冶金、化工、电力、医药和食品等各工业部门。其结构越来越复杂,它的高效负荷,安全、长期运转与企业的经济效益有直接关系。 本课题来源于安徽晋煤中能化工股份有限公司20万吨／年合成氨原料路线调整改造工程MCO空压机组。该合成氨原料路线调整改造工程压缩机选用沈阳鼓风机集团有限公司生产的MCO1004+3BCL407压缩机组,汽轮机选用杭州汽轮机股份有限公司生产的NKS40/56汽轮机。 本课题的研究内容主要包括以下几个方面： (1)分析了MCO空压机组导叶调节器结构以及国外空压机组导叶调节器执行机构现状,阐明了MCO执行机构的拉力、推力计算过程及选型要求,确定导叶执行机构自动控制过程。 (2)分析MCO空压机组轴承振动和位移的监控和保护,通过倍频完成开车,完成机组监测保护系统设计。 (3)分析MCO空压机组入口介质温度随四季变化的特点,研发出适合于空压机组的防喘振控制方案。 (4)根据MCO空压机组工艺流程特点,完成MCO空压机组工艺流程设计。 (5)分析TS3000工作原理,阐明控制系统的重要性、必要性及可靠性,完成MCO空压机组控制系统设计。 本文阐述了空压机组的特点、仪表选型依据及优化控制,为进一步研究MCO空压机组控制系统提供了参考。
[Abstract]:MCO air compressor is a supercharging device that controls the process gas pressure at the outlet of compressor through its own compression grade. MCO air compressor has been widely used in air separation and metallurgy. Chemical industry, electricity, medicine and food and other industrial sectors. Its structure is becoming more and more complex, and its high efficiency load, safety and long-term operation are directly related to the economic benefits of the enterprise. This subject comes from Anhui Jinneng Chemical Co., Ltd. 200000 tons / year synthetic ammonia raw material route adjustment and transformation project MCO air compressor unit. The compressor of the synthetic ammonia raw material route adjustment and transformation project is MCO1004 3BCL407 compressor produced by Shenyang Blower Group Co., Ltd., and the steam turbine is NKS40/56 steam turbine produced by Hangzhou Steam Turbine Co., Ltd. The research contents of this subject mainly include the following aspects: (1) the structure of guide vane regulator of MCO air compressor unit and the present situation of actuator of guide vane regulator of air compressor unit in foreign countries are analyzed, and the tension of MCO actuator is expounded. The thrust calculation process and selection requirements are determined, and the automatic control process of guide vane actuator is determined. (2) the monitoring and protection of bearing vibration and displacement of MCO air compressor unit are analyzed, and the monitoring and protection system design of the unit is completed by frequency doubling. (3) the characteristics of the inlet medium temperature of MCO air compressor unit with four seasons are analyzed, and the anti-surge control scheme suitable for air compressor unit is developed. (4) according to the technological process characteristics of MCO air compressor unit, the technological process design of MCO air compressor unit is completed. (5) the working principle of TS3000 is analyzed, the importance, necessity and reliability of the control system are expounded, and the control system design of MCO air compressor unit is completed. This paper expounds the characteristics of air compressor unit, the basis of instrument selection and optimal control, which provides a reference for further study of the control system of MCO air compressor unit.
