基于大面积BDD电极的工业用电解水处理器的设计

摘要

为了解决大面积BDD电极的实际应用问题,设计了基于大面积BDD电极的水处理器,确定了反应器的类型为箱式循环式反应器,电极联结方式为单极式,液路连接为并联液路.为了使水处理器具有更好的通用性,设计电解槽中用于固定电极的卡槽长度超过100 mm,可以同时放置2块50 mm×100 mm×2 mm的电极构成更大面积的100 mm×100 mm×2 mm电极.对设计的电解槽进行仿真,研究了500 mL/min和800 mL/min 2种不同流量条件下电解槽内水的流线、流速和温度.仿真结果发现,当流量为800 mL/min时,水流在电解槽内形成的涡流少,水流停滞少,并且出口处的水温不高,水流不断带走电极上的温度,系统散热很好.%In order to solve the problem of practical application of large area BDD electrode,this paper designs a water processor based on large area BDD electrode.Monopole type electric connection and liquid path in parallel are applied to the electrolytic cell.In order to make the water processor more general,the length of card slot for fixing electrode is more than 100 mm,that two electrodes (100×100×2 mm) can be placed in it.The flow field is investigated by using finite element method (FEM).The simulation results show that when the flow rate is 800ml/min,the vortex flow formed in the electrolytic cell is less,the water stagnation is less,the water temperature in outlet is not high and cooling system is very good.
