污泥干化压滤机
本专利技术属于污泥处理,尤其涉及一种污泥干化压滤机。
技术介绍
干化污泥的常规工艺是:污泥经带式压滤机或离心过滤机或板框压滤机干化后通过输送机收集,然后再传送至堆泥场。上述处理工艺存在的问题为:1、污泥经普通带式压滤机或离心过滤机干化后,通常含水率在80%左右,污泥所受的挤压过滤压力较低,无法提高脱水效果;2、普通板框压滤机和隔膜板框压滤机通过高压泵加入污泥,市政污泥压滤后含水率通常大于65%。污泥在添加石灰的条件下、含水率达到60%左右,污泥处置成本增大,污泥添加石灰后无法作为肥料资源;3、板框压滤机一般通过2MPa的高压泵加入污泥,工作时间长能耗高。隔膜板框压滤机的二次压缩比值小,是污泥压滤脱水的致命缺点,且工作效率低占用立体空间较大。专利文献公开号107673579A公开了一种智能污泥干化机,包括热泵装置和干燥装置,所述热泵装置包括压缩机、冷凝器、蒸发器和制冷剂,其特征在于:所述干燥装置包括空气、风机和网带,所述空气先通过所述热泵装置的冷凝器加热,再通过所述风机加压后,对所述网带上的污泥进行除湿干燥,产生的湿空气经所述热泵装置的蒸发器冷凝后分离成冷凝水和空气,所述冷凝水经排水管外排,所述空气重新进入所述热泵装置的冷凝器循环加热。专利文献公开号203625218U公开了一种污泥干化机,其特征在于:包括有干化室与循环风加热室,干化室顶部设有热风入口,近底部位置处设有循环风出口与补充风入口,底部设有补充风出口,在干化室内从上至下平行且错开式设置有若干层由变频电机驱动的不锈钢网带式传送台,最底层的不锈钢网带式传送台的传送末端伸出干化室,循环风 ...
