Heat exchange network optimization method

Abstract

The invention provides a heat exchange network optimization method, and belongs to the technical field of engineering optimization methods. The method comprises the following steps: 1, determining a heat exchange network optimization object; secondly, data related to the heat exchange network in the object range is collected and sorted; thirdly, the heat exchange network is evaluated and analyzed, and the heat exchange network is optimized based on the evaluation and analysis result; 4, carrying out implementation and safety analysis on the optimized heat exchange network, and if the implementation difficulty is high or a safety problem exists, carrying out optimization adjustment on the heat exchange network again until the implementation difficulty is low and the safety problem does not exist; and 5, taking the optimal economic benefit as a target, and finely adjusting the optimized heat exchange network to obtain a final transformation scheme. According to the method, energy utilization efficiency and economic benefits are considered, enforceable and safety factors are also considered, so that the transformation scheme optimized by the method is high in enforceability, safe, reliable and closer to production practice, and great economic benefits are brought to enterprises.
