在北半球的冬天,那里许多化工厂的空压机运行时,都面临着结冰的现象。这样会损害空压机的运行。例如,大型离心式或往复式空压机的进口管吸入含有冰块的空气,会损害其叶片或其它内部零件。 当温度降到冰点以下时,为防护起见,消冰的方法是采用从空压机排出口或中间级引出压缩空气来预热进口空气,使进口空气温度达到露点以上,或者使用另外的预热方法,例如 During the Northern Hemisphere winter, many of the chemical plants’ air compressors faced icing when they were operating. This will damage the compressor operation. For example, a large centrifugal or reciprocating compressor inlet tube sucks in air containing ice and can damage its blades or other internal components. When the temperature drops below freezing, for protection, the method of de-icing is to preheat the inlet air with compressed air drawn from the air outlet or intermediate stage of the compressor so that the inlet air temperature is above the dew point or with additional preheating Method, for example
