电解车间的设计范围-中英对照
电解车间的设计范围和操作条件
电解车间设计必须保证在离子膜周期和设备负荷所有阶段符合说明书中的强制操作条件 （包括正常的操作、开车和停车）。这些条件根据离子
膜寿命和电解车间工作状态而改变。
离子膜寿命周期开始采用较高供给温度。由于离子膜寿命的原因，在规定负荷范围内，增加电压将导致电解槽内产生巨大的热能，因此要求降
低供给温度。而且，离子膜的使用寿命是由于过高和过低的负荷决定的，必须遵循电解车间里工艺设计全部操作条件、设备尺寸和流程控制系
统的规定。
设备设计人必须考虑全部项目设计条件对关键设备的影响。
流程设计考虑
盐水进料系统
供给盐水主要工艺设计特征，在电解槽加满和冲洗停车要求中作出定义正如3.2.3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。
对于全部的选择方案而言，重要的是提供盐水进料低流量跳闸装置，整流器断开以防止阳极液室的盐水水位下降操作而造成的组件损坏。由于
短期流量控制可造成干扰，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，电解槽的盐水进料必须灌满，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.由一个带盐水进料槽的预留容器，通过一个完整的泵送系统提供。
以上两例中，电解槽盐水进料的灌满流程通过紧急启动/停车阀门控制，而不受盐水供给流量控制阀控制。
随后的灌满流程十分重要，电解槽经过盐水冲洗（流量相当于至少一个电解槽阳极液容量），从而除去残余的氯气。供应的冲洗盐水需要具有
较高的完整性，可采用下列3种方式之一提供：
1.从灌满流程使用的同一压力槽中提供，增加压力槽容量，以便能提供两种进料方式。
2.从供给盐水槽里的预留容器中提供，盐水槽中要求具有较低的水位警报，以便在警报水位有足够的容积冲洗全部电解槽。提供一个可靠抽水
系统，包括2个盐水进料泵，要求装备有备用电源。
3.装备有冲洗和灌满盐水进料槽。防止低水位跳闸，保证盐水灌满留出足够的容积。泵送系统必须具有极高的完整性，可以进行冲洗和灌满作
业。
对于所有的选择而言，在长期停车极化条件期间，必须保证对电解槽装满和冲洗流程提供盐水，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。
Electrolytic workshop design scope and operating conditions
Design must guarantee in ionic membrane electrolysis workshop cycle and equipment load stage all conform to the specifications of mandatory operating conditions (including normal operation, driving and parking). These conditions according to the ion
Film life and electrolytic workshop working state.
High ionic membrane life cycle started using supply temperature. Because of ionic membrane life, within the scope of the specified load, increase the voltage will lead to huge heat generated in the electrolytic cell so requires
Low supply temperature. Moreover, the service life of ionic membrane is due to too high and too low load, must follow the electrolysis workshop process design in all operating conditions, the size of the equipment and process control system
The provisions of the system.
Equipment the designer must consider all project design conditions on the influence of key equipment.
Process design consideration
salt water feeding system
Supply brine process design features, mainly in electrolytic cell fill and flushing the parking requirements been defined as described in section 3.2.3. This chapter content of these regulations and other additional requirements
In this paper.
For all of the options, it is important to provide low feed brine flow tripping device, rectifier to disconnect in order to prevent the anolyte chamber of saline water level drop operation caused by the damage of components. Due to the
Short-term traffic control can cause interference in low flow fault reserve the trip delay in 60 seconds, prevent unnecessary trip.
Parking electrolytic cell, cell feed brine must fill up, maintain a complete feed process. Electrolytic tank filling process has two acceptable options provide:
(1) is provided by a dedicated pressure tank.
By a feed trough with brine reserve container, through a complete system of pumping.
Both cases the electrolytic tank brine feeding filling process through the emergency start/stop valve control, and there is no salt water supply flow control valve control.
Subsequent filling process is very important, electrolytic cell by saline irrigation (liquid flow is equivalent to at least one cell anodes capacity), so as to remove residual chlorine. Supply needs to be washing brine
High integrity, can use one of the following three ways:
1. From the fill process USES the same pressure tank, tank capacity increase pressure, so as to provide two feeding way.
2. On the supply of salt reserve container provided in the tank, salt in the sink with low water level alarm, in order to have sufficient volume of water in the alarm flush all the electrolytic cell. To provide a reliable water pumping
System, including two salt water feed pump, equipped with backup power.
3. Equipped with washing and filling of salt water feed tank. To prevent the low water level tripping, ensure the brine fill enough volume. The pumping system must have high integrity, washing and filling can be made
Industry.
For all options, during the long-term parking polarization condition, must make the pledge that we shall provide the brine of electrolyzer with and flushing process, at the same time guarantee for forced cooling of electrolyzer fuck before drainage
Make it. Requires at least two salt water supply pump installation.
