Design and implementation of sensing and warning system for chimney corrosion

针对采用湿法脱硫工艺后的烟囱腐蚀问题,设计开发了一套实用性较高的超低功耗烟囱腐蚀度预警系统。介绍了该系统的硬件及软件设计:选用了超低功耗单片机MSP430F149作为控制芯片;使用交流电代替直流电作为传感导线的供电电源,以减少导线极化损耗;在单片机控制逻辑中简化程序,以降低运行负荷、延长使用寿命。该系统能保证维护人员及时发现渗漏点并进行维修,有效实现了安全、稳定、可靠并低投入的烟囱渗漏检测预警,达到了安全生产的目的。

This paper introduced a practical ultra-low power sensing and warning system for chimney corrosion based on the problem that chimney will be corrosive after wet flue gas desulfurization process. The design for hardware and software of this system was mainly introduced in this paper. The ultra-low power microcontroller MSP430F149 was chosen as a control chip,and alternating current was used instead of direct current power supply as a sensing wire to reduce the lead polarization loss. Also,simplifying procedures in microcontroller control logic can reduce operating load and prolong its service life. The system ensures the maintenance personnel can detect and repair leaks in time,which effectively achieve a safe,stable,reliable and low-input chimney leak detection warning system,and a purpose of safe production.
