Description

污泥细化设备
技术领域
本发明涉及一种污水处理设备,特别是涉及一种污泥细化设备。
背景技术
目前在污水处理过程中,均会产生一种副产物,污泥。污泥的成分包括多种物质,包括细菌菌体,胶体和各种微生物,目前,我国的城市污泥排放量达到千万吨,而且每年还以10%的速度在增长,这无疑给环境带来很大的负担和压力。现有的城市污泥,含有有机物,氮,钾等微量元素。有机物未经过稳定化的处理,很容易腐烂。从而营养元素与重金属物质也会造成二次污染。
因此,这就需要对污泥进行水处理,目前的处理方法是,包括重力沉降,机械脱水和超声波脱水。重力沉降可以使得污泥固含物重量提高2%-5%,而机械脱水通常需要较为复杂的设备,而超声波脱水方式较为科学。
现有的技术中公开有了超声波对污泥进行脱水的方法,但是简单的超声波脱水法,对于除去水分有一定效果,但是由于污泥中杂物繁多,因此,简单的超声波脱水法对于后期的污泥处理和资源回收再利用是不利的。
因此,这就需要一种对污泥预先处理的设备以解决污泥杂质多,颗粒度不均衡的缺陷。
发明内容
本发明的目的是提供一种过污泥进行细压处理,以解决现有技术中的污泥处理污泥杂质多,颗粒度不均匀的缺陷。
本发明中的设备方案是这样实现的:一种污泥细化设备,其用于对污泥进行细压处理,其特征在于:包括集料仓,所述集料仓底部设有多组辊筒,所述集料仓顶部设有双层过滤网,所述双层过滤网上层孔径大于下层孔径;所述辊筒底部设有传送带,所传送带顶部的设有用于挤压污泥成片状的污泥辊压筒
本发明的总体构思是:通过采用污泥进行辊压,使得污泥颗粒更加紧凑,杂质粒度变小更均匀后,便于后续的污泥处理。
本发明中,作为进一步的改进,所述污泥细化设备中的辊筒包括两个粗辊压筒,所述粗辊压筒中间设有调节辊压筒,所述调节辊压筒下部设有一个花键辊压筒,所述粗辊压筒,调节辊压筒和花键辊压筒相互相切接壤。
发明中,作为上述技术方案的进一步改进,所述粗辊压筒,调节辊压筒和花键辊压筒均活动固定在固定板上。
本发明与现有技术相比,具有如下有益效果:
1.本发明中,可以将污泥的颗粒度均衡到处理级别水平,颗粒度差别率小于±0.02mm,并且能够对污泥中的杂质进行细化,有利于后期污泥的处理。
2.本发明可以有效的减少污泥的杂质。
3.本发明制作成本低,便于本行业推广和运用。
附图说明
图1是本发明污泥细化设备的结构示意图;
图中零部件名称:
粗辊压筒1、调节辊压筒2、花键辊压筒3、污泥辊压筒4、传送带5、固定带6、挡泥板7、集料仓8、双层过滤网9。
具体实施方式
以下结合附图及实施例描述本发明过滤式污泥脱水处理设备及其处理方法。
如图1所示,本发明中的污泥细化设备包括集料仓8,集料仓8顶部设有双层过滤网9,第一层过滤网孔径小于第二层过滤网孔径;下部位置设有多组辊筒,多组辊筒包括两个粗辊压筒1,粗辊压筒1中间设有调节辊压筒2,调节辊压筒2下部设有一个花键辊压筒3,粗辊压筒1,调节辊压筒2和花键辊压筒3相互相切接壤。上述的粗辊压筒1,调节辊压筒2和花键辊压筒3均活动固定在固定板6上;
而上述设备的污泥细化是这样实现的:
污泥细化:将污泥进行打捞后,在其他设备中进行预脱水,将污泥水含水量降低至75%以下,引入污泥细化设备,并通过集料仓8顶部双层过滤网后,使得污泥速度缓慢的进入到多组辊筒中,通过粗辊压筒1和调节辊压筒2进行污泥挤压磨细外后,通过花键辊压筒3对污泥进行点压随后排入传送带5中;随后运送至后续的设备中进行污泥脱水处理即可,上述步骤后,污泥被细化后的颗粒大小为0.05~0.06mm。
