Description
技术领域
本发明涉及一种反渗透纯化水***,特别是一种可用于医药技术领域的反渗透纯化水***。
背景技术
反渗透纯水***是通过反渗透膜法来制取纯水的装置。其主要的工作原理是用足够的压力使溶液中的溶剂(一般是水)通过反渗透膜(或称半透膜)而分离出来,因为这个过程和自然渗透的方向相反,因此称为反渗透。反渗透法能适应各类含盐量的原水,尤其是在高含盐量的水处理工程中,能获得很好的技术经济效益。反渗透法的脱盐率提高,回收率高,运行稳定,占地面积小,操作简便,能在除盐的同时,也将大部分细菌、胶体及大分子量的有机物去除。目前,亦有各种公开的反渗透纯化水***专利。例如,CN106477744A公开了一种纯化水***,包括用于存储原水的原水箱、用于净化原水的过滤***、用于原水反渗透的反渗透***、纯化水箱、用于纯化水杀菌的杀菌***和纯化水输送***,所述用于净化原水的过滤***包括依次连接的多介质过滤器、活性炭过滤器和精密过滤器,所述多介质过滤器的进水口与原水箱的出水口联通,所述多介质过滤器的进水口与原水箱的出水口之间还设置有原水泵,所述精密过滤器与活性炭过滤器连通的进水口处还设置有阻垢剂投加装置。该纯化水***通过一系列的过滤、渗透和杀菌,克服了现有技术的缺陷,实现了制备用水的纯化。现有的纯化水***大多注重于原水的防渗透处理,在进行初步过滤(主要包括机械过滤和活性炭过滤)前,一般都没有对原水进行进一步的处理,极有可能会影响到反渗透处理后的水质。
发明内容
本发明要解决的技术问题是提供一种结构简单合理的反渗透纯化水***,可对原水进行多重处理,从而制得适用于医药技术领域的纯化水。
为解决上述技术问题,本发明采用以下技术方案:
一种反渗透纯化水***,包括依次通过管道连接的原水箱、软化器、机械过滤器、活性炭过滤器、精密过滤器、一级反渗透器、一级水箱、二级反渗透器、二级水箱、EDI纯水机、纯水箱和超滤机,所述原水箱外设置有空气泵,空气泵通过管道连通于原水箱的下部,所述纯水箱和超滤机之间设置有杀菌装置;所述精密过滤器和一级反渗透器之间的管路上设置有一级高压泵,所述一级水箱和二级反渗透器之间的管路上设置有一二级高压泵;所述二级水箱和EDI纯水机之间的管路上设置有增压泵。
作为上述技术方案的进一步改进,所述的反渗透纯化水***管路上设置有多个水泵,以便提高整个***的输送能力。其中,所述原水箱和软化器之间的管路上设置有原水泵;所述纯水箱和超滤机之间的管路上设置有出水泵。
优选的,所述杀菌装置为紫外线杀菌器。
优选的,所述反渗透纯化水***的操作压力范围为1~1.5MPa。
本发明的有益效果为:
本发明的反渗透纯化水***在进行机械过滤和活性炭过滤前,可对原水进行空气泵加氧和原水水质的软化,此后再经过多重过滤、二次反渗透、EDI纯水和超滤膜处理后,可获得水质优良的纯化水,该***具有高效率、低成本的优点。
