1. Technical ideas
Aiming at the system's release of waste heat resources, based on the current process route, combined with the system process, the system's waste heat resource generation method, the amount of waste heat resources, and the parameter change range are investigated, and the returned steam is preferentially returned to the system for reuse according to the released steam. The principle of reasonable use of the minimum released steam can realize the cascade utilization of waste heat resources, improve the utilization of waste heat resources and the economic benefits of the system. Through the recovery of waste heat resources, combined with the actual cooling and heating loads and power equipment configuration in the system process network, it can be used to drive loads (such as pumps, fans), generate electricity, cool (for air conditioning or equipment cooling), and heat (such as heating, desalinated water) Deaeration, preheating medium, etc.).
