Abstract
A zero-power-consumption self-adaptive distributed waste heat recovery and utilization system for an ethylene device is provided. The waste heat recovery and utilization system includes a waste heat collection pipeline system, multiple waste heat recovery devices arranged in groups, and a waste heat return pipeline system. The waste heat collection pipeline system is configured to lead out a working medium having waste heat from a waste heat source of the ethylene device and distribute the working medium to the waste heat recovery devices. The waste heat recovery devices are configured to heat combustion-supporting air of a bottom burner of an ethylene cracking furnace through the waste heat. The waste heat return pipeline system is configured to transport the working medium that has undergone waste heat recovery and utilization back to the waste heat source.
