煤炭制样单机除尘器
本技术涉及煤炭质量检测采、制、化三个环节中的制样室除尘装置,具体说是一种用于煤炭制样室除尘的单机除尘器。
技术介绍
粉尘是由自然力或机械力产生的,能够悬浮于空气中的固体细小微粒。国际上将粒径小于75μm的固体悬浮物定义为粉尘。在煤样制备过程中,试样需要通过破碎、缩分、混合和干燥等步骤,制备成能够代表原来样品特性的分析用样品。样品的破碎主要通过破碎设备(例如锤式破碎机)将大颗粒的样品通过挤压、撞击、切割等操作来制成分析样品。样品在制作的过程中会产生大量粉尘,这些粉尘从破碎设备中的缝隙中泄露,弥漫于整个制样室,造成扬尘。对制样工人的身体健康产生了极大的危害,是产生尘肺等职业病的主要原因。同时粉尘散落在机械转动部位,也会加快设备的磨损,减少使用寿命。制样室中制样设备有几台甚至十几台,现在制样室的除尘解决办法是采用一套大型工业除尘设备,除尘设备单独安放在一个单独房间,除尘系统通过管道与每一台破碎设备相连,并且和破碎设备进行信号传输,进行除尘工作的电器控制。这种大型除尘设备目前存以下问题:一是价格高,在20万左右,只有少部分用户能够接受,推广难度大;二是 ...
