除塵器使用中的注意事項

   使用中要防止氣體在袋室內冷卻到露點以下,特別是在負壓下使用袋式除塵器更應注意.   使用中要防止氣體在袋室內冷卻到露點以下,特別是在負壓下使用袋式除塵器更應注意.由于其外殼常常會有空氣漏入,使袋室氣體溫度低于露點,濾袋就會受潮,致使灰塵不是松散地,而是粘糊地附著在濾袋上,把織物孔眼堵死,造成清灰失效,使除塵器壓降過大,無法繼續運行,有的產生糊袋無法除塵.|

  對于袋式除塵器來說,其使用溫度取決于兩個因素,第一是濾料的最高承受溫度,第二是氣體溫度必須在露點溫度以上.目前,由于玻纖濾料的大量選用,其最高使用溫度可達280℃,對高于這一溫度的氣體必須采取降溫措施,對低于露點溫度的氣體必須采取提溫措施.對袋式除塵器來說,使用溫度與除塵效率關系并不明顯,這一點不同于電除塵,對電除塵器來說,溫度的變化會影響到粉塵的比電阻等影響除塵效率.a
