      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.
