其现场采用布袋除尘器进行高温烟气净化。从设备的实际性能考虑，滤袋容许承受温度一般为100℃左右,与高温烟气温度（一般可以达到300℃）相比差距很大，所以必须首先需要对高温烟气进行降温,并对降温过程进行实时监控。具体办法是：在吸风管道前后两端各安装一个温度传感器，分别用于检测烟气吸口处和布袋除尘器入口处的烟气温度；在管道中部安装一个电动蝶阀，当两个温度传感器感检测到的温度超过设定值时电动蝶阀打开，从而混入一定量的冷空气，把烟气冷却。


Bag filter is used to purify high-temperature flue gas on site. Considering the actual performance of the equipment, the allowable temperature of the filter bag is generally about 100 ℃, which is far from the high-temperature flue gas temperature (generally up to 300 ℃), so it is necessary to cool the high-temperature flue gas and monitor the cooling process in real time. The specific method is: install a temperature sensor at the front and rear ends of the air suction pipe to detect the flue gas temperature at the flue gas suction port and the inlet of the bag filter respectively; An electric butterfly valve is installed in the middle of the pipeline. When the temperature detected by the two temperature sensors exceeds the set value, the electric butterfly valve opens, so as to mix a certain amount of cold air to cool the flue gas.
