标准摘要
[中文适用范围]： 本文件规定了在开放循环冷却水系统中缓蚀阻垢剂试验评价装置的设计、运行及水质污染等方面的一般要求和参数。本文件涉及的参数包括试验单元设计、操作、水质和污染物等，还包括试验台装置的设计和操作以及试验单元中需要评价的参数。本文件规定了在试验规模测试计划中选择特定循环冷却水系统用水处理方案的准则。本文件仅适用于开放循环冷却水系统。不适用于闭式冷却系统和一次性通过的冷却水系统。 本文件仅适用于包含壳管式换热器且换热管为标准未涂覆光管的系统，且冷却水在管侧流动。本文件不适用于壳侧进水、板框式换热器以及螺旋式换热器和其他换热设备。然而，在正确设置测试条件以模拟更复杂的传热装置的表面温度和剪切应力时，测试结果可以预测设计中运行换热器的结果。本文件中建立的测试准则无意规范通常由水处理公司作为其专有产品开发计划的一部分进行的台架试验和小试试验的类型。然而，水处理公司可以选择将本文件中的准则作为指导，用于其自身产品开发测试程序的制定。 本文件规定了缓蚀阻垢剂试验评价装置的一般要求和建议。在设计缓蚀阻垢剂试验评价方案时，应考虑对循环冷却水系统的机械设计和运行进行评估。精确模拟特定工厂负荷或水流模式可能不可行。污染在试验冷却塔中的发展方式与实际系统不同，因此可能存在折衷。所有情况下都应遵循工厂的设计和操作，任何偏差均应在测试报告中记录。 为提高效率，可以在同一时间对两个或多个相同的试验单元进行研究。除了向循环冷却水中添加缓蚀阻垢剂外，还通常使用一些水处理方法来处理循环冷却水，包括：- 石灰软化法；- 离子交换法；- 反渗透脱盐法；- 电化学处理法；- 电磁法；- 旁流过滤法。这些方法在5.4中进行了讨论。设计试验装置时应特别注意使用这些方法对添加剂选择的影响。 [外文原描述]： This document specifies general requirements and parameters for the pilot test evaluation of corrosion and scaling control additives in open recirculating cooling water systems. This document covers parameters including test unit design, operation, water quality and contamination. It also covers the design and operation of pilot test devices as well as parameters to be evaluated in pilot test units. This document covers the criteria that are used in pilot scale testing programmes for selecting water treatment programmes for specific recirculating cooling water systems. This document is only applicable to open recirculating cooling water systems. It does not apply to closed cooling systems and once-through cooling water systems. This document applies only to systems that incorporate shell and tube heat exchangers with standard uncoated smooth tubes and cooling water on the tube side. This document does not apply to heat exchangers with shell-side water, plate and frame and/or spiral heat exchangers and other heat exchange devices. However, when the test conditions are properly set up to model the surface temperature and shear stress in more complex heat transfer devices, the test results can predict the results of operating heat exchangers of that design. The test criteria established in this document are not intended to govern the type of bench and pilot scale testing normally carried out by water treatment companies as part of their proprietary product development programmes. However, water treatment companies can choose to use the criteria in this document as guidelines in the development of their own product development test procedures.
