本实用新型涉及的是反渗透净水机,具体是一种可反清洗自动控制式的反渗透净水机。 The utility model relates to a reverse osmosis water purifier, in particular to a reverse osmosis water purifier capable of reverse cleaning and automatic control.
背景技术 Background technique
水是人类生命的源泉,人们对饮用水质的要求及相应的标准在不断提高。但由于工业废水和生活污水等水体排放量的不断增加,致使水源污染日益加剧。人类经历了由最初的简单的沉淀净水到传统的煮沸处理,发展到现在的深度净化饮用水。目前解决饮用水污染问题有两条途径:一是通过保护饮用水水源,选用优质饮用水水源;二是强化饮用水处理工艺。在发达国家饮用水净化处理工艺已经很成熟而且净水机的使用也相当普及。 Water is the source of human life, and people's requirements for drinking water quality and corresponding standards are constantly improving. However, due to the continuous increase in the discharge of industrial wastewater and domestic sewage and other water bodies, the pollution of water sources has become increasingly serious. Human beings have experienced the initial simple precipitation water purification to the traditional boiling treatment, and developed to the current deep purification of drinking water. At present, there are two ways to solve the problem of drinking water pollution: one is to protect drinking water sources and select high-quality drinking water sources; the other is to strengthen the drinking water treatment process. In developed countries, the drinking water purification process is very mature and the use of water purifiers is quite popular.
反渗透RO(Reverse osmosis,简称为RO)膜是近年来发展的一种新型净化材料。该材料利用的是反渗透技术,即在高于溶液渗透压力的作用下,只充许水透过,而其它物质不能透过半透膜面从而将过些物质的水分离开来,从而使水由高含盐量逆流到低含盐量,去除水中绝大部分有害物质、重金属、可溶性固体等,只有水分子方能透过反渗透膜而成为纯水。由于逆渗透膜的孔径仅0.0001微米,一个细菌要缩小4000倍,过滤性病毒也要缩小200倍以上才能通过,因此能够有效地去除水中的溶解盐类、胶体、微生物、有机物等。目前的反渗透净水机有很多种,但由于使用过程中RO膜得不到及时冲洗,从而使膜上沉淀了太多的杂质,会影响反渗透净水机的过滤效果,大大减少了反渗透净水机的使用寿命。因此,需要发明一种可以定时反清洗的反渗透净水机。 Reverse osmosis RO (Reverse osmosis, referred to as RO) membrane is a new type of purification material developed in recent years. The material uses reverse osmosis technology, that is, under the action of the osmotic pressure higher than the solution, only water is allowed to pass through, while other substances cannot pass through the semi-permeable membrane surface, so as to separate the moisture of some substances, so that the water can pass through. High salinity counterflows to low salinity, removes most harmful substances, heavy metals, soluble solids, etc. in the water, and only water molecules can pass through the reverse osmosis membrane to become pure water. Since the pore size of the reverse osmosis membrane is only 0.0001 microns, a bacterium must be reduced by 4000 times, and a filter virus must be reduced by more than 200 times to pass through, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. There are many kinds of reverse osmosis water purifiers at present, but because the RO membrane cannot be washed in time during use, too many impurities are deposited on the membrane, which will affect the filtration effect of the reverse osmosis water purifier and greatly reduce the reverse osmosis water purifier. The service life of the osmotic water purifier. Therefore, need to invent a kind of reverse osmosis water purifier that can regularly backwash.

RO清洗系统10是对反渗透装置7定时进行清洗的装置。高压泵6和RO清洗系统10之间的管线上安装有电磁阀13,反渗透装置7和浓水出口之间的管线上安装有电磁阀13a,PLC的输出端分别和电磁阀13、电磁阀13a相连接。因此,由PLC定时打开电磁阀13和电磁阀13a,对膜组件表面进行低压清洗,将膜组件内的浓水冲走,防止反渗透膜浓水侧结垢,延长清洗周期。
The
为了对纯净水和浓水的量进行检测,可在纯净水出口处和浓水出口处均安装有流量计。 In order to detect the amount of pure water and concentrated water, flowmeters can be installed at the outlet of pure water and concentrated water.
使用时,首先启动原水泵2,10s后高压泵6启动,2s后电动慢开阀启动,同时电磁阀13a打开,阻垢剂加注系统启动。原水经过原水箱1、原水泵2,进入进水管线,然后经过了多介质过滤器3和活性炭过滤器4的过滤作用,除去一部分的杂质,经过阻垢剂加注系统向原水中添加适当的阻垢剂,经过保安过滤器5时,再次去除部分杂质,然后进入高压泵6进行加压。加压后的大部分高压水进入反渗透装置7进行彻底过滤,过滤后的纯净水储存在纯净水水箱8中,通过纯净水泵9输入到用水地点。由于高压泵6和RO清洗系统10之间的管线上安装有电磁阀13,当需要对反渗透装置7中的过滤膜进行清洗时,由PLC向电磁阀13发出指令,电磁阀13开启,高压水通过RO清洗系统10对反渗透装置7进行清洗,同时打开浓水出口处的电磁阀13a,清洗后的含有大量杂质的浓水从浓水出口排出。清洗完毕后,由PLC向电磁阀13发出指令,电磁阀13关闭,高压水重新进入反渗透装置7进行过滤。
When in use, start the raw water pump 2 first, start the high-
