摘要
随着节能减排在发电厂、钢厂等高耗能企业的实施,对其产生的过热蒸汽测量尤为重要。涡街流量计传感器检测感应元件为压电陶瓷,由于其极化时居里温度的限制,只能在低于240℃介质中使用。为了提高传感器耐受温度,利用技术冲突以及物理冲突理论,建立传感器系统功能模型,然后进行因果分析,确定冲突区域,在此基础上,确定多个创新方案,通过对比确定最优解。
With the implementation of energy conservation and emission reduction in high energy-consuming enterprises such aspower plants and steel mills,the superheated steam temperature measurement is very important.However the sensor of the vortexstreet flow meter is piezoelectric ceramic,as a result of the limitation of Curie temperature,sensor can only work in less than240degrees medium.In order to raise the heat resistance temperature we will build sensor system function mold,analyze cause andresult relationships and determine the conflict area.Many innovation schemes can be obtained by conflict theory and physical conflicttheory,the optimal solution can be determined by comparing.
