袋式过滤器排泄阀及留渣情况的分析与解决

袋式过滤器的操作是非常简单的,但是在使用过程中还是要注意下它的排泄阀及留渣情况,下面就一起来了解下吧~

袋式过滤器在泵启动后,其过滤机上压力表就会微微上升,其设备的初始压力为0.05MPa左右,在使用时会随着其使用时间的延长,这样缸内的滤渣就会逐渐增多,这样当压力达到0.4MPa时,应停机打开筒盖,检查滤机袋留渣情况。

袋式过滤器的压力一般会调节在0.1-0.3MPa比较合适,在进行使用时可以通过回流管路或者泵上回流阀来进行调节,其设备的过滤压力过高这样就会直接损坏滤袋以及保护网,在进行使用时需要格外注意。

袋式过滤器在平时使用的过程中千万不能在设备有压力的情况下开盖,否则剩留液体可能喷出,并造成液体流失和人员伤害。闭输入阀;出口处有压力时,关闭输出阀。确认排气阀所接管道已被接到安全处或吸料口后,再打开排气阀,防止液体对工作人员及周围环境造成伤害和污染。

袋式过滤器有排泄阀的,确认排泄液接到回收处,打开排泄阀;待袋式过滤机中的剩留液体经排泄阀流尽,关闭排泄阀。此排放工作可配合加压方式完成。
