一种输煤皮带除尘器高落差输灰缓冲降尘装置
本技术属于除尘器辅助设备
,具体涉及一种输煤皮带除尘器高落差输灰缓冲降尘装置。
技术介绍
输煤皮带输送过程中除尘器输灰系统卸料阀向皮带卸灰时,由于落差产生冲击正压,造成罩内煤尘逸向工作区逸散,对已降落到设备上、皮带通廊、厂房地面的粉尘,在设备运转、人员走动时将产生二次扬尘,长期产生大量生产性粉尘可能造成以下的危害:1.粉尘对人体健康的危害,接触生产性粉尘除了可能引起尘肺等呼吸系统职业病,还可引起眼睛及皮肤等疾病。2.粉尘爆炸危害,分散在空气(或可燃气)中的某些粉尘,在同时具备氧气、高温源、可燃粉尘、容器条件下,会燃烧、爆炸。粉尘的爆炸在瞬间产生,伴随着高温、高压、势空气膨胀形成的冲击波具有很大的摧毁力和破坏性。3.粉尘对能见度的影响,当光线通过含尘介质时,由于粉尘对光的吸收、散射等作用,光强会减弱,出现能见度降低的情况,这给工人的操作和检修带来极大的不便,同时也会给安全带来隐患。4.粉尘对设备的影响,含尘气流在运动时与壁面冲撞,产生切削和摩擦,引起磨损。粉尘污染还能影响设备的使用寿命。
