防止工业烟尘污染是环保的重要任务之一。为了消除工业烟尘污染,首先要知道烟尘排放量,因此必须对烟尘源进行监测、自动显示和超标报警。烟道里的烟尘浊度是用通过光在烟道里传输过程中的变化大小来检测的。如果烟道浊度增加,光源发出的光被烟尘颗粒的吸收和折射增加,到达光检测器的光减少,因而光检测器输出信号的强弱便可反映烟道浊度的变化。
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.
