    防止工業煙塵污染是環保的重要任務之一。為了消除工業煙塵污染,首先要知道煙塵排放量,因此必須對煙塵源進行監測、自動顯示和超標報警。煙道里的煙塵濁度是用通過光在煙道里傳輸過程中的變化大小來檢測的。如果煙道濁度增加,光源發出的光被煙塵顆粒的吸收和折射增加,到達光檢測器的光減少,因而光檢測器輸出信號的強弱便可反映煙道濁度的變化。
    Preventing industrial dust pollution is one of the important tasks of environmental protection. In order to eliminate industrial smoke pollution, first of all, we must know the amount of smoke and dust emissions. wushui.37ix.com.cndiaosurw.37ix.com.cnzhagungp.37ix.com.cnzhibanx.37ix.com.cnwalengzhi.37ix.com.cn xianweisu.37ix.com.cnTherefore, we must monitor, display and alarm the sources of smoke and dust automatically. The smoke turbidity in flue is measured by the change of light in the process of transmission in flue. If the flue turbidity increases, the light emitted by the light source is absorbed and refracted by the dust particles, and the light arriving at the photodetector decreases. Therefore, the intensity of the output signal of the photodetector can reflect the change of flue turbidity.
