    二 解 决 方 案   The solution

 

       1 工 艺 流 程

 

        离子交换工艺方式:

           原水→原水增压泵→预处理系统→精密过滤器→阳树脂过滤床→阴树脂过滤床→阴阳树脂混床→微孔过滤器→用水点。

 

       反渗透工艺方式:

           原水→原水增压泵→预处理系统→精密过滤器→反渗透系统→纯化水箱→纯水泵→微孔过滤器→用水点。

 

       EDI+反渗透方式:

           原水→原水增压泵→预处理系统→精密过滤器→双级反渗透系统→中间水泵→EDI系统→抛光混床→微孔过滤器→用水点。

 

       1 technological process

 

        Ion exchange process:

           Raw water, raw water booster pump and pretreatment system, precision filter, Yang resin filter bed, anion exchange resin filter bed, anion and cation resin in the mixed bed, porous filters, water points。

 

       Reverse osmosis process:

           Raw water, raw water booster pump, pretreatment system, precision filter, reverse osmosis system, purified water tank, water pump, micro hole filter, water point。

 

       EDI+ reverse osmosis:

           Raw water, raw water booster pump, pre processing system, precision filter, dual stage reverse osmosis system, middle water pump, EDI system, polishing mixed bed, porous filters, water。

 

     2 设 备 特 点

      (1)采用PLC+触摸屏自动控制方式,稳定可靠、精致美观、一键式启动、操作简单方便。 。

      (2)人性化3D设计,符合人机工程学;触摸屏、开关、仪器、仪表设立高度位置,符合国人平均身高方便人工操作。

      (3)对各组件的动作如:水泵、阀门、水罐液位、设有动态监控画面(有需要可以升级远程监控)。

      (4)设管理权限,分别为:管理员、工程师、操作员三种级别的管理。

      (5)手动、自动模式转换方便,具备特殊提醒功能,以防止非操作人员误操作。

      (6)人性化的报警记录与提示功能;当遇到滤材更换周期到、满水、缺水、低压、超压在触摸屏事件记录栏会记录,当遇到水质、压力、流量出现异常会发出报警。

      (7)设水质纠偏功能,有最低使用水质预警功能,不会出现突发紧急的状态。

      (8)制水系统与供水系统分开控制,如遇更换耗材,可不必停止供水或者制水。

      (9)RO产水、冲洗时间可设定,当用水高峰期,可调节产水时间,使用水点稳定用水。

 

     2 Equipment characteristics

      (1)PLC+ touch screen automatic control method, stable and reliable, delicate and beautiful, one button start, easy to operate。

      (2)Humanized 3D design, in accordance with human engineering; touch screen, switch, instrument, instrument set up a high position, in accordance with the average height of the Chinese people to facilitate the manual operation。

      (3)The various components of the action such as: water pump, valve, water level, a dynamic monitoring screen (there is a need to upgrade the remote monitoring)。

      (4)Set management authority, respectively: the administrator, engineers, operators of the three levels of management。

      (5)Manual, automatic mode conversion is convenient, with special remind function, to prevent non operator error operation。

      (6)Humanized alarm record and prompting function; when filter replacement cycle, full of water, water shortage, low pressure and overpressure in the touch screen event record column will record when meet water quality, pressure, flow appear abnormal alarm。

      (7)Water quality rectification function, there is a minimum use of water quality warning function, there will not be a state of emergency。

      (8)The water supply system and the water supply system are separately controlled, and the water supply and the water supply system can not be stopped。

 

      (9)RO water production, washing time can be set, when the peak of water, can regulate the production of water, the use of water stable water。
