气化炉激冷室、旋风分离器以及水洗塔液位测量管嘴堵塞和差压变送器膜片的氢渗透腐蚀在国内煤化工行业是个普遍的问题,通过多种工况的试验分析,并对现有的冲洗水装置进行改造,解决了测量管嘴堵塞问题,探讨了用雷达液位计进行测量的方法.%Both nozzle blocking of level measurement tube of the gasifier' s shock chamber,cyclone separator and water scrubber and the hydrogen permeation corrosion of the differential pressure transmitter generally troubles the coal chemical industry at home.The experiments at various conditions and the improvement on the water-flushing device in service were implemented to solve nozzle blocking of level measurement tube ; and making use of the radar level gauge in level measurement was discussed.
