电除尘器振打控制器的设计 摘要 目前大气污染是一个备受关注的焦点，造成这种污染的主要源头是燃煤电厂。随着政府对气体污染物排放标准的日益严格，大多数企业建立了除尘效率较高的电除尘器振打控制系统，从而有效地减少了废气中粉尘的排放量，从而保护了环境。在电除尘器振打控制系统的设计中，如何控制振打锤的振打以及如何应用人机界面来方便地控制振打的运行是设计的关键之一。本设计重点介绍了电除尘器振打控制器的设计理论即：采用人机界面设计成的控制画面及功能说明。并电除尘器阴阳极振打系统，PLC；人机界面 ESP rapping controller Abstract At present, air pollution is a focus of concern, causing a major source of this pollution is coal-fired power plant. Gaseous pollutants with the Government of the increasingly stringent emission standards, the majority of enterprise to establish a high collection efficiency ESP vibration control system, which effectively reduces emissions of dust emissions, thereby protecting the environment. Rapping in the electrostatic precipitator control system design, how to control the vibration of the vibration hammer and how to facilitate the application of human-machine interface to control the operation of vibration is one of the keys to the design. The design focuses on the electrostatic precipitator of the vibration controller design theory that is: how PLC ESP rapping on some of the control, how to achieve the sub-branch vibration hammer out the best vibration control and timing , as well as the use of human-computer interface designed to control, and the functionality of the screen. And describes the development of the electrostatic precipitator, composition and principles of ESP Rapping polar system of yin and yang, PLC characteristics and development, PLC and the principle of the composition, PLC and expand the selection and analysis module, the implementation of component selection and characteristics and so on.
