摘　　要：棉纺织企业的粉尘大多属于可燃性粉尘,在达到爆炸危险浓度,具有足够的氧气,遇到明火,就会发生爆炸事故。对棉纺织企业清花梳棉车间有安全隐患的蜂窝除尘机组进行调研,测试机组内部粉尘浓度,第一级粉尘浓度最低为2.968mg/m^(3)(生产涤纤维),最高为32.261mg/m^(3)(生产棉纤维),均低于粉尘爆炸下限50g/m^(3);而第二级更是远低于爆炸下限,完全没有达到爆炸危险浓度。但为了降低爆炸风险,建议在除尘机组安装泄爆装置,并增加火花探测和熄火系统,彻底消除产生爆炸的安全隐患。Most of the dust in cotton textile enterprises is combustible dust.When it reaches the dangerous concentration of explosion and has enough oxygen,an explosion accident will occur when encountering an open flame.The honeycomb dedusting unit with potential safety hazards in the clear-cut carding workshop of cotton textile enterprises was investigated.The dust concentration inside the unit was tested.The minimum dust concentration of the first level was 2.968 mg/m^(3)(for polyester fiber production),and the maximum was 32.261 mg/m^(3)(for cotton fiber production),both of which were lower than the lower dust explosion limit of 50 g/m^(3).The second level was far below than the lower explosion limit,and did not reach the explosion hazard concentration.However,in order to reduce the risk of explosion,it was recommended to install an explosion venting device in the dust removal unit,and add spark detection and flameout systems to completely eliminate the potential safety hazards of explosion.
