氨气传感器的研究

Research of Ammonia Gas Sensor

燃煤电厂脱硝过程中的氨逃逸现象,对环境造成严重的破坏,需要开发连续,稳定的氨气传感器对氨气进行监测。本综述主要介绍光学类传感器、金属氧化物氨气传感器和导电聚合物氨气传感器机理、性质和特点,重点阐述新型氨气传感器对氨气优良的检测特性,从而为快速简单的监控电厂烟气中的氨气含量,提供技术上的支持。

Ammonia escape in the process of denitration in the coal-fired power plants cause severe damage to the environment. It is important to develop a continues,stable ammonia gas sensor for monitoring ammonia. In this paper mainly introduces the mechanism,property and characteristic of optical ammonia gas sensors, mental oxide ammonia sensors and conductive polymer ammonia gas sensors,emphasis on new gas sensor for detecting ammonia excellent feature,which is quick and easy monitoring of ammonia content in the flue gas of power plant,providing technical support.
