The invention discloses a chemical waste heat utilization system comprising an energy storage unit and a design method thereof. The design method comprises the following steps: (1) obtaining stream data of an industrial system; (2) formulating an energy target for the industrial system of each single cycle; (3) based on the energy characteristics of each stream of the industrial system in a single period, the industrial system is divided into blocks, and a heat exchange network structure corresponding to the industrial system in the period is obtained through calculation; and (4) the multi-period heat exchange network structure and the energy target are integrated, the optimal installation position of the multi-layer energy storage unit is determined, and the industrial system heat exchange network comprising the energy storage unit is obtained. According to the method, on the basis of single-cycle heat exchange network topology optimization design, actual working condition parameters are combined, the energy
