Description

一种带恒电流输出直流电源的卷式电除盐器
技术领域
本实用新型涉及一种水处理装置，尤其是涉及一种带恒电流输出直流电源的卷式电除盐器。
背景技术
现有工业用水除盐提纯的水处理的方法中，较为先进的方法是将电渗析技术和离子交换技术相结合制取超纯水。例如，专利号为98223514的实用新型专利公开了一种螺旋卷式电除盐器水处理设备，它主要将阴阳离子交换膜与绝缘网隔板制成一特殊的膜袋式浓水流道单元，并与浓水配集管的侧壁相连通，每相邻的浓水流道单元之间夹入一张绝缘网隔板构成可充填入离子交换树脂的淡水流道单元，然后以浓水配集管为中心卷绕成圆筒体结构，再包以电极壳体。但现有的电除盐器两电极的设置较复杂，尤其是两电极间的控制电流仅简单通过桥式整流获得，易受水温、水量、水质等参数的变化影响而不稳定，结果造成出水水质也不稳定。
发明内容
本实用新型主要是解决现有技术电除盐器所存在的两电极的设置较复杂、两电极间的控制电流的因水温、水量、水质等参数的变化而不稳定，结果造成出水水质不稳定等的技术问题。
本实用新型的上述技术问题主要是通过下述技术方案得以解决的：一种带恒电流输出直流电源的卷式电除盐器，包括由阴阳离子交换膜，浓、淡水的配集管，设于浓、淡水通道内的网隔板和正负电极的电除盐器主体构件，且上述若干层的阴阳离子交换膜和设于浓、淡水通道内的网隔板均以浓水集(配)管为中心轴卷制成圆筒体，并在各淡水流道单元内充填有离子交换树脂，所述的浓水集(配)管兼作一电极，而包置于圆筒体外的金属壳体为另一电极，两电极之间设置有恒电流输出直流电源。
所述的浓水集(配)管接恒电流输出直流电源的正极，置于圆筒体外的金属壳体接恒电流输出直流电源的负极。
所述的恒电流输出直流电源为可调的单相自耦变压器T的输入端接交流电源，所述的变压器T的输出端分别与整流器ZD的输入端相连；所述的整流器ZD的直流输出端与滤波电容C并联后，其一端接三端可调式集成电压调整器IC的输入端，另一端与电位器W一端及电除盐器正电极相连；所述的电压调整器IC的调整端与电位器W的另一端相连，电压调整器IC的调整端和输出端之间并联一电阻R，电压调整器IC的输出端与电除盐器负电极相连。
所述的自耦变压器T的调压转动轴与电位器W旋转轴之间设置有机械联动机构。
所述的自耦变压器T的调压转动轴与小型直流电机旋转轴相连接，所述的直流电机与电压自动控制器相连，电压自动控制器接恒电流输出直流电源电路。
所述的电压自动控制器包括取样电路、标准电压电路和差值放大电路。
因此，本实用新型具有：1.两电极结构简单、合理；2.因设置了恒电流输出直流电源电路，两电极间的控制电流的不受电除盐器内的水温、水量、水质等参数的变化的影响，从而保证出水水质稳定、水质好；3.因直流电源的功耗基本恒定，节能。
附图说明
附图1是本实用新型的横截面结构示意图；
附图2是本实用新型的恒电流输出直流电源的电原理图。
具体实施方式
下面通过实施例，并结合附图，对本实用新型的技术方案作进一步具体的说明。
实施例：图1中浓水集(配)管1为中间阻断的金属管，位于横截面圆的圆心处，其上半段作为集水管，下半段作为配水管，同时兼作卷式电除盐器负电极。由一对阴阳离子交换膜组成的膜袋结构的浓水通道5及其中网隔板和相邻两浓水通道5之间的淡水通道4网隔板，均以浓水集(配)管为中心轴卷制成圆筒体，在圆筒体外包置一个筒状的金属壳体2为正电极，正负电极的极桩设置在外壳体3上。图2为恒电流输出直流电源的电原理图，图2中变压器T为可调的单相自耦变压器，变压器T的输入端接电网交流电源，变压器T的两个输出端分别与整流器ZD的输入端相连。整流器ZD的直流输出端与滤波电容C并联后，一端接三端可调式集成电压调整器IC的输入端Vin；另一端与电位器W一端、电位器W的调节端及电除盐器正电极相连。电压调整器IC的调整端ADJ与电位器W的另一端相连。电压调整器IC的调整端ADJ和输出端Vout之间并联一电阻W。恒电流输出直流电源工作时交流电经变压器T变压、整流器ZD整流、滤波电容C滤波后输入三端可调式集成电压调整器IC，电压调整器IC中的功率元件吸收多余的电功率实现输出电压的稳定，该电路不仅可连续调整直流输出电压，而且在改变输出电压时能够保持额定输出的电流不变、电压稳定。调整电压可通过调节自耦变压器T的调压手柄来达到，电位器作为辅助的调压；也可在自耦变压器T的调压转动轴与电位器W旋转轴之间设置机械联动机构，例如皮带或齿轮啮合联动同步调节。
电除盐器工作时先缓慢增大整流器的电压达到300伏，随着电除盐器中浓水电导率的逐步上升，电流也随只增大。当电流超过2.5A时，再调节电路的电压将电流稳定在2.5A，从而保持电除盐器出水水质稳定。
本实用新型也可采用自动控制来实现调压，将自耦变压器T的调压转动轴与小型直流电机旋转轴及减速机构相连接，该直流电机与一电压自动控制器相连，电压自动控制器接恒电流输出直流电源电路；电压自动控制器包括取样电路、标准电压电路和差值放大电路。通过取样电路和标准电压电路使输出的电流经常地与标准电压进行比较，比较差值经放大电路放大，控制直流电机及减速机构转动自耦变压器T的调压转动轴调节电压，保持输出电流稳定。
