空分项目中拖动空压机的方式有2种,一种是电机拖动,一种是汽轮机拖动。选择拖动空压机的原动机,主要还是以经济和安全为原则。随着我国经济的蓬勃发展,特别是近年来冶金、化工、石化等行业的飞速发展,要求空分设备向大型化发展,空压机的功率也随之越来越高;而且现在一般新型化工厂很少采用电机拖动的形式。由此可见,采用汽轮机拖动空压机的需求是很大的。
将汽轮机和空压机作为一个统一的被控对象,其优势主要体现在以下几个方面:
人机界面统一:可以与空分系统画面相互切换,画面风格统一。
数据共享:直接与空分系统共享数据。
组态方便:符合国际标准的组态语言和人性化的组态界面方便用户对汽轮机进行算法组态和画面组态。
控制策略灵活:可以根据用户的实际需求修改和丰富控制策略,空压机的测点可以直接参与汽轮机的联锁与控制。There are two ways to drive the air compressor in the air separation project, one is motor drive and the other is steam turbine drive. The prime mover for dragging the air compressor is mainly based on the principles of economy and safety. With the vigorous development of China's economy, especially the rapid development of metallurgy, chemical industry, petrochemical and other industries in recent years, air separation equipment is required to develop to large-scale, and the power of air compressor is also higher and higher; And now the general new chemical plants rarely use the form of motor drive. It can be seen that there is a great demand for using steam turbine to drive air compressor.
Taking steam turbine and air compressor as a unified controlled object, its advantages are mainly reflected in the following aspects:
Unified man-machine interface: it can switch with the screen of air separation system, and the screen style is unified.
Data sharing: directly share data with air separation system.
Convenient configuration: the configuration language in line with international standards and humanized configuration interface facilitate the user to configure the algorithm and screen of the steam turbine.
Flexible control strategy: the control strategy can be modified and enriched according to the actual needs of users, and the measuring points of air compressor can directly participate in the interlocking and control of steam turbine.
