The invention is a low energy consumption circulation technology for direct drinking water. Direct drinking water without disinfection agent, easy to breed bacteria, in the pipeline transportation, straight drinking water in the pipeline for a long time may breed bacteria, resulting in water quality is not qualified, in order to solve this problem, generally need to direct drinking water in the pipeline cycle disinfection. At present, public drinking water circulating water supply system, using a water pump, which provides network power, network and keep enough pressure, therefore, the pump needs a larger lift, but in the circulatory system, poor energy-saving effect of frequency conversion technology in general, and because the system must be uninterrupted operation, large energy consumption. For the above problems, the invention adopts a new scheme, this scheme uses a pressure storage barrel, storage of drinking water water circulating pump is responsible for water circulation, separate water supply and circulation, the circulation pump only can overcome the long run loss, so the choice of low lift pump. Low flow, so as to achieve the purpose of energy saving.

直饮水低能耗循环技术
本专利技术涉及一种直饮水循环技术,尤其是涉及一种直饮水低能耗循环技术。
技术介绍
直饮水由于不含消毒药剂,易滋生细菌,在管道输送时,水在管道中长时间停留可能滋生细菌导致水质不合格,为了解决这个问题,一般需让直饮水在管道中循环进行消毒。目前,公知的直饮水循环供水系统,采用一台水泵,既提供管网循环动力,又保持管网足够的压力,因此,水泵需要较大扬程,但是在循环系统中,通常的变频调速节能技术效果欠佳,又因为系统必须不间断运行,能耗较大。
技术实现思路
征对以上问题,本专利技术采用一种全新的方案,该方案用一个储压桶,存储直饮水水压,循环泵只需负责管网水循环,将供水和循环分开,长期运行的循环泵只需克服沿程损失即可,因此可选择低扬程,低流量的循环泵,从而达到节能降耗的目的。本专利技术解决其技术问题所采用的技术方案是:一种供水方案,其特征在于,由储压罐1、循环泵2、压缩气泵3组成。所述供水方案,其特征在于,源水管与所述储压罐1连接,向所述储压罐1注水并压缩罐内气体,使罐内压强升高。所述供水方案,其特征在于,所述储压罐1出口管设所述循环泵2,所述循环泵2出口管网与储压罐循环回水口连接,形成闭合回路。所述供水方案,其特征在于,用户用水量较小时,所述循环泵2提供水循环动力,闭合回路中直饮水形成循环。所述供水方案,其特征在于,用户用水量较大时,储压罐出水口与循环回水口可同时向用户供水,供水量增大一倍,因此在所述供水方案设计时,可降低管径尺寸,从而节省材料,降低投资成本。所述供水方案,其特征在于,所述储压罐1与所述压缩气泵3通过气管连接,当所述储压罐1内气体不足时 ...
