中文摘要:
      为加强消防系统的安全性和实用性,实现甲醇罐区喷淋冷却水的节水回用,依据相关规范,从形式选择、设计计算、系统布置和操作控制等方面阐述了消防及冷却系统设计的优化方法。根据点火源模型的计算结果,提出甲醇罐区泡沫消防管道设计宜采取分散布置,替代原来集中布置的敷设形式,优化后夏季喷淋冷却系统的水回用率达到了98.25%。通过优化,降低了储罐事故状态下热辐射对相邻泡沫管道的影响程度,减少了消防车械的拥堵状况,提高了消防精度。此外,循环夏季喷淋冷却系统还有效减少了企业污水的排放量,人工操作量小,实现了较为智能的冷却水回用功能。
英文摘要:
      In order to enhance the safety and practicability of fire protection system, and realize water saving and reuse of spray cooling water in methanol tank farm, according to the relevant standards, the form of system selection, the calculation method, the system arrangement and the operation process of fire fighting and cooling system are expounded. According to the calculation result of the ignition source model, the optimization design of foam fire pipeline in methanol storage tank is put forward, and the layout of the pipeline is replaced by "scatter arrangement" instead of "concentrated arrangement". The overall water reuse rate of the cooling water system for summer spraying could be up to 98.25%. Through this optimization, the impact of thermal radiation on the adjacent storage tank foam pipe is reduced under the condition of accidents, so does the congestion of fire trucks, and the accuracy of fire fighting is improved. In addition, the system effectively reduces the discharge of sewage in enterprises, and the manual operation is simple, so that the intelligent cooling water reuse function is realized.
