Waste heat circulation system of floating production platform and floating production platform

Abstract

The invention relates to a waste heat circulation system of a floating type production platform and the floating type production platform. The waste heat circulation system comprises a waste heat recovery device, an auxiliary heating device, a heating medium user module, a dual-fuel generator set, a cooling water heat exchanger and a seawater heat exchanger. A cooling water outlet of the dual-fuel generator set is connected with a hot side inlet of the cooling water heat exchanger, and a cold side outlet of the cooling water heat exchanger is connected with an inlet of the waste heat recovery device or an inlet of the auxiliary heating device. An outlet of the waste heat recovery device or the auxiliary heating device is connected with an inlet of the heating medium user module; an outlet of the heating medium user module is connected with a cold side inlet of the cooling water heat exchanger, and a hot side outlet of the cooling water heat exchanger is connected with a hot side inlet of the seawater heat exchanger. The cooling water outlet of the dual-fuel generator set enables high-temperature waste water to pass through the cooling water heat exchanger, the waste heat recovery device or the auxiliary heating device, waste heat is recovered and used for the heating medium user module, energy consumption is reduced, cost is reduced, and the energy utilization rate is increased.
