Description

超导磁体污水絮凝净化装置
技术领域
本发明涉及一种含磁性物质的污水处理净化装置,特别涉及一种超导磁体污水絮凝净化装置。
背景技术
磁种式污水处理技术,是通过向污水中添加絮凝剂、助凝剂及磁种,利用絮凝剂、助凝剂使污物絮凝,利用磁吸的方式使混有磁种的絮凝状污物聚集和与水分离出来。例如中国专利文献CN101838037A公开的“一种磁种式污水处理方法及装置”,是利用带非导磁板的永磁铁将含磁种的絮凝污物吸附住,然后依附在带有非导磁板的永磁体板的两面,待带有非导磁板的永磁体板的两面所吸附的胶体状絮凝污染物足够多时,将带有非导磁板的永磁体板从污水中移离出来,并通过刮板将带有非导磁板的永磁体板两面的胶体状絮凝污染物连同磁种刮到非导磁板上,然后通过推刮器将非导磁板上的胶体状絮凝污染物连同磁种,刮送到从污染物中分离磁种过程中的污泥输送皮带上。
这种污水处理装置,永磁体需要不断放入污水中进行吸附和从污水中移离出来以刮除磁种及絮凝污染物,因此生产连续性很差,而且由于永磁体磁场强度低,因此吸附力小,处理速度较慢。
超导磁体利用超导电磁线圈产生电磁力,螺线型超导磁体室温孔内的磁场强度远大于永磁铁。目前,超导磁体用于矿浆中铁磁性材料的分选,已经取得了不错的技术效果。
将超导磁体应用于污水处理,将取得永磁铁污水处理技术不可比拟的技术效果。
发明内容
本发明的目的在于提供一种能够用于污水净化的超导磁体污水絮凝净化装置,使得污水处理的生产连续性好、处理速度和处理效率高并且对磁性物质的吸附力强。
本发明的技术方案是这样实现的:
超导磁体污水絮凝净化装置,包括具有室温孔的螺线管式超导磁体、穿过所述室温孔运动的分离框;所述分离框内设置有非磁性筛;在所述室温孔的入口处设置有污水排放口,并且所述污水排放口位于所述分离框上方。
上述超导磁体污水絮凝净化装置,所述非磁性筛与所述分离框底面的夹角为30度—75度,使分离框非磁性筛上部的絮凝分离空间成楔形,有利于絮凝沉降的污泥是从最底部逐渐向上填充聚集,而保证上面筛网畅通。
考虑到分离框高度和在运行方向上水平宽度的比例,上述超导磁体污水絮凝净化装置,所述非磁性筛与所述分离框底面的夹角为45度—60度。
所述分离框中筛网下面的分离框底为多孔板,其总开孔面积小于所述分离框上方入口的面积,以使污水在分离框内有一定停留时间而不是直接冲下,保证污水有足够絮凝时间。
所述分离框是在驱动装置驱动下在所述超导磁体室温孔内作往复式运动。上述超导磁体污水絮凝净化装置,室温孔内出口一端在室温孔内或室温孔外低磁场区设置从下向上的冲击水流或气流,以利于分离框内污泥的排 出。冲击水流或气流设置在室温孔内时,对应地在室温孔内反冲段设置有上盖,并且所述上盖位于所述分离框的上方,以防止污泥从上方冒出到室温孔内。
所述分离框也可以是在驱动装置驱动下在所述超导磁体室温孔内外作环形循环式运动,这样不但可实现完全连续生产,而且当分离框转动到超导磁体下方分离框口向下时,在重力作用下分离框内污泥可以实现自动倒卸污泥。为进一步使粘附于非磁性筛上的污泥掉落,可以在室温孔外采用自上而下或自下而上的冲击气流或冲击水流,将污泥直接冲下,或者使非磁性筛受冲击而震动,将污泥抖落。
本发明的有益效果是:本发明的超导磁体污水絮凝净化装置,超导磁体产生的磁场强度高,使得对磁性物质的吸附力大,可以使絮凝污物快速沉降,处理速度和处理效率高;超导磁体不动,利用分离框进出超导磁体,生产连续性好操作简便;本发明的超导磁体污水絮凝净化装置能够使污水中含磁种子的絮凝污染物快速絮凝沉降并从水中分离,而使污水得到净化,减轻环境污染并节约资源。

具体实施方式
结合附图对本发明做进一步的说明:
如图1所示,本实施例超导磁体污水絮凝净化装置,包括具有室温孔的螺线管式超导磁体1、穿过所述室温孔的链条2和安装在所述链条2上的分离框3;所述分离框3内设置有非磁性筛4,并且所述非磁性筛4与所述分离框3底面的夹角为50度;在所述室温孔的入口处设置有污水排放口6,并且所述污水排放口6位于所述分离框3上方以向分离框内进污水。
所述链条2以及链条驱动的分离框是张在位于超导磁体室温孔外的主驱动轮7和从动轮8上,电机驱动主驱动轮带动链条循环运动,从而带动所述分离框3在所述超导磁体室温孔内、外作环形循环式运动,沿整个链条长度方向均安装有分离框,这样分离框依次进出超导磁体室温孔形成循环。筛面上的沉淀物(积聚物)污泥在旋转到磁体下方低磁场区会因重力自行落下。为迫使(或加速)其脱落,设置自下向上的冲击气流(或水流)以使筛面上的沉淀物(积聚物)被振动与筛面脱离,当然如图1中所示采用自上而下的冲击气流(或水流)F,冲击力方向与重力方向一致,更有利于筛面上的沉淀物(积聚物)落下。
当然如果在室温孔内污水被净化处理完毕时,为排出沉淀物而设置的冲击气流或水流可以设置在室温孔内靠近出口的一段,为从下向上吹,在所述室温孔的出口处位于该反冲段的位置设置有上盖5,并且所述上盖5位于所述分离框3的上方,防止所述分离框3内的磁性污泥向上移出掉落到超导磁体内。
污水中事先加入了混有磁种的絮凝剂,使得经过含磁种絮凝剂絮凝的污水,在螺线管式超导磁体1的室温孔内,在强磁场作用下,利用磁场力使污物快速絮凝沉降,并被非磁性筛隔离住停留在筛面上,净化后的污水通过非磁性筛并向下流出分离框,然后从室温孔内流出。经过本实施例超导磁体污水絮凝净化装置处理后的污水出水口有尽可能好的清水指标,减轻环境污染并节约资源。
本实施例的超导磁体污水絮凝净化装置生产连续性好,超导磁体产生的磁场强度高,使得对磁性物质的吸附力大,处理速度和处理效率高。
如图2所示,本实施例超导磁体污水絮凝净化装置也可以设计成为往复式运动的形式,驱动装置往复拉链条2使分离框3穿过超导磁体1的室温孔作水平往复运动。污水通过污水排入口6加入分离框,在磁导磁体室温孔内时快速絮凝沉降,实现污染物与水的分离。当所述分离框3运动到另一端时,通过加自下而上的冲击气流或水流把所述分离框3中的筛面上的沉淀物(积聚物)冲出,然后再进行下一次分选。当冲击气流或水流设置在超导磁体室温孔内时,同样在室温孔内的反冲段要在分离框顶部位置设置上盖5。往复式运动形式的超导磁体污水絮凝净化装置同样也可以实现本发明创造的目的,但是其生产连续性不如环形循环式运动的超导磁体污水絮凝净化装置。
在另外一些实施例中,所述非磁性筛4与所述分离框3底面的夹角可以为30度—75度之间的任意数值;优选所述非磁性筛4与所述分离框3底面的夹角为45度—60度;使得所述非磁性筛4在所述分离框3中达到最佳的倾斜角度。以使污泥是在底部由下向上汇集,而不是均匀平铺在筛面上。水平设置非磁性筛,由于絮凝沉降的污泥均匀平铺在筛面上,只要很薄一层就会影响筛面的透水性。
