Title:
ZERO-POWER-CONSUMPTION ADAPTIVE DISTRIBUTED WASTE HEAT RECYCLING SYSTEM FOR ETHYLENE PLANT
Document Type and Number:
WIPO Patent Application WO/2023/221274
Kind Code:
A1
Abstract:
A zero-power-consumption adaptive distributed waste heat recycling system for an ethylene plant, comprising a waste heat collection pipeline system, waste heat recovery devices (9) arranged in groups, and a waste heat return pipeline system. The waste heat collection pipeline system leads out a working medium containing waste heat from a waste heat source of the ethylene plant and distributes the working medium to each waste heat recovery device (9); the waste heat recovery device (9) heats combustion-supporting air of a combustor at the bottom of an ethylene cracking furnace by using the waste heat; the waste heat return pipeline system returns the working medium in which the waste heat is recycled to an original waste heat source. The waste heat collection pipeline system comprises a collection master pipe (16), a collection trunk pipes (7), and collection branch pipes (12); the collection master pipe 16 is provided with master pipe flow control elements (17), the collection trunk pipes (7) are provided with trunk pipe flow control elements (6), and the collection branch pipes (12) are provided with branch pipe flow control elements (11), so that the flow of each group of waste heat recovery devices (9) is uniformly distributed. By means of flow distribution design, adaptive adjustment can be achieved, and the flow uniformity of each group of waste heat recovery devices (9) can be achieved without adding control valves, thereby ensuring the uniformity of a temperature field of a furnace chamber of the ethylene cracking furnace.
