碱液循环 (阴极) 系统-中英对照
供给碱液的主要工艺设计特征，在电解槽加满和冲洗停车要求中作出定义正如3.2.4章节中的描述。本章节内容对这些规定和其它额外要求进行
了阐述。
必须提供碱液进料低流量跳闸装置，通过断开整流器，防止阳极液室的碱液水位下降和组件损坏。由于短期流量控制造成的干扰，在低流量故
障时候保留60秒的断开延迟，防止不必要的跳闸。
电解槽停车时，电解槽的碱液进料必须立即进行灌满，并保持完整的进料流程。电解槽的灌满流程有两项可接受选项提供：
1.由一个专用的压力槽提供。
2.由一个预留容器在盐水进料槽通过一个完整的泵送系统提供。
以上两例中，电解槽碱液进料的灌满流程通过紧急启动/停车阀门控制，而不受碱液供给流量控制阀控制。
在长期停车极化条件期间，所有的选择必须保证装满和冲洗电解槽的盐水进料，同时保证在排水之前进行电解槽的强制冷却操作。要求至少安
装二台盐水供给泵。
输送管线设计
排放总管布局
对于BICHLORTM 电解槽而言，产生的液体和气体流入每个单元槽的顶部时并不分开，而是顺BICHLORTM出口总管排出，同时传输气体和液体两个
产品。这些气体和液体通常用一个较大的T形连接装置通过出口总管排出。
在气体/液体分离点的输送管线必须设计为，液体采用重力方式分离到阳极液和阴极液槽。在全部可能的操作条件下，出口输送管线里的液体水
位必须保持在气体液体分离点的水平下面。防止给离子膜和电解槽造成任何背面加压，避免将液体带进气体总管。
为了这种情况，电解车间通常设置在底楼，方便对电解液槽发出指令。电解槽的气体和液体分开点之间的升高差别和电解液槽的入口，必须能
承受液体压降、电解槽和大气压，以及电解液槽的满负荷操作压力 （250 mbar） 之间的压力差。如图4.4.1 说明
在输送管线的排水处设置进料封闭器，当电解槽准备维修时，电解槽流体出口处设置有一个隔间或者铲形物，确保其它电解槽里没有生产的气
体进入该通道。 经验表明，连接电解车间液体压力槽顶部的输送管道可能发生问题，当隔间背后侧的出气口可能发生故障¬——或许受气压影
响和从压力槽产生释放气体。连接电解车间压力槽的底部可以使这个问题减小到最少，但会挡住封闭器，造成排水和收集破碎残渣的困难。在
总管下方一半的位置采用一个斜角连接是最好的选择。
Lye recycling (cathode) system
Supply main technological design features of lye in electrolytic cell fill and flushing the parking requirements been defined as described in section 3.2.4. This chapter is about the content of regulations and other additional requirements in this paper.
Low alkali liquor feed flow tripping device, must be provided by disconnect rectifier, prevent the anolyte chamber of lye water level decline and damage of components. Interference caused by short-term flow control, in the low flow
Disabled when disconnection of reserved 60 seconds delay, prevent unnecessary trip.
Parking electrolytic cell, cell inlet must immediately lye to fill up, and keep a complete feed process. Electrolytic tank filling process has two acceptable options provide:
(1) is provided by a dedicated pressure tank.
2. Reserve by a container in salt water feed channel through a complete system of pumping.
Both cases the electrolyser lye feed fill process through the emergency start/stop valve control, and there is no lye supply flow control valve control.
During the long-term parking polarization conditions, all you have to choose to ensure full and flushing feed brine electrolyzer, at the same time guarantee for forced cooling of electrolyzer operation before drainage. Requires at least Ann
Two salt water supply pump.
Pipeline design
Discharge duct layout
For BICHLORTM cell produced by liquid and gas flow into each unit tank top is not separated, but a suitable discharge BICHLORTM export manager, at the same time two transmission of gas and liquid
Products. Usually these gases and liquids with a larger tee joint device through the export manager.
In gas/liquid separation point must be designed for conveying pipeline, and liquid separation by way of gravity to the liquid anode and cathode liquid trough. In all possible operating conditions, the export of liquid water in the pipeline
Who must remain under the level of gas liquid separation point. To prevent to cause any pressure on the back of ionic membrane and electrolytic cell, to avoid the liquid into gas main.
To this case, the electrolytic workshop is usually set on the ground floor, convenient for electrolyte slot issue instructions. Electrolytic tank of gas and liquid separation point and the rise of differences between the electrolyte slot entrance, must be able to
Liquid pressure drop and electrolytic cell and atmospheric pressure, and electrolyte slot at full capacity the pressure differential between the operating pressure (250 mbar). As shown in figure 4.4.1 instructions
A setting in the drainage pipeline feed closure, when cell ready to repair, cell fluid outlet set have a compartment or spade, ensure there is no other cell production
Access to the channel. Experience has shown that connecting the electrolytic workshop liquid pressure tank at the top of the pipeline problem can occur, when the lateral compartment behind the outlet may be down, perhaps by air pressure
Ring and release gases from pressure tank. Connect the bottom of the electrolysis workshop pressure tank can reduce the problem to a minimum, but will block closure, cause problems for drainage and collecting crushing residue. in
The position of the main below half USES a bevel connection is the best choice.
