Title:
SYSTEM FOR PRODUCING COMPRESSED AIR BY UTILIZING WASTE HEAT OF SHIP
Document Type and Number:
WIPO Patent Application WO/2019/201033
Kind Code:
A1
Abstract:
A system for producing compressed air by utilizing waste heat of a ship, relating to the technical field of ship construction. The system comprises a power subsystem and a compression subsystem, wherein the power subsystem comprises an evaporator (1), a turboexpander (2), a condenser (3), and a booster pump (4), wherein the evaporator (1), the turboexpander (2), the condenser (3) and the booster pump (4) constitute a circulation loop, and a working medium is heated by means of cylinder sleeve water to further drive the turboexpander (2) to rotate; the compression subsystem comprises a compressor (7), an air bottle (8) and an air supply pipeline (9), wherein the compressor (7) is connected to the turboexpander (2) by means of a coupling, an air inlet of the compressor (7) communicates with an external air pipeline, an air outlet of the compressor (7) communicates with an air inlet of the air bottle (8) by means of a compressed air pipeline (10), and an air outlet of the air bottle (8) communicates with the air supply pipeline (9). The system utilizes waste heat of cylinder sleeve water of a main engine and/or auxiliary engine and waste heat of a waste heat boiler and/or an economizer of a ship to produce compressed air, thus having good energy saving and synergistic effects.
