Abstract
Claims
1. An ORC waste heat power generation skid for an offshore platform for generating power to an expander generator, characterized in that, The system includes a working fluid pump connected to a circulation system. The circulation system includes a preheater and an evaporator connected to each other. After the working fluid is injected by the pump, it enters the preheater. The preheater is used to input liquid working fluid into the evaporator. The evaporator changes the working fluid from liquid to gas, and the gaseous working fluid enters the expander generator to generate electricity. The circulation system also includes a condenser connected to the expander generator and the preheater. The condenser is used to change the working fluid after power generation back to liquid and then circulate it back into the preheater. The circulation system also includes a regenerator connected to both the condenser and the preheater. The regenerator is used to cool the working fluid from the condenser again.
2. The offshore platform ORC waste heat power generation skid of claim 1, wherein, The condenser is positioned above the working fluid pump.
3. The offshore platform ORC waste heat power generation skid of claim 1, wherein, The condenser is also connected to the evaporator and can convert the excess gaseous working fluid in the evaporator into liquid. The excess liquid working fluid can be circulated together with the liquid working fluid after power generation into the preheater.
4. The offshore platform ORC waste heat power generation skid of claim 1, wherein, The regenerator and condenser are arranged side by side.
5. The offshore platform ORC waste heat power generation skid of claim 1, wherein, The regenerator has an inlet and an outlet, with the inlet being lower than the outlet.
6. The ORC power generation skid from offshore platform waste heat according to any one of claims 1-5, characterized in that, There are at least two working fluid pumps, and the condenser is connected to the preheater through each working fluid pump. The outlet of the condenser is connected to the inlet of each working fluid pump, and the outlet of each working fluid pump is connected to the inlet of the preheater. The outlet of the working fluid pump is also connected to a bypass pipe, the end of which is connected to the inlet of the working fluid pump. A regulating valve for adjusting the flow rate of the working fluid is installed on the bypass pipe. The outlet of the preheater is connected to the inlet of the evaporator.
7. The offshore platform ORC waste heat power generation skid-mounted device according to claim 6, characterized in that, The working fluid pump is a single-unit horizontal pump.
8. The offshore platform ORC waste heat power generation skid of claim 6, wherein, The preheater, evaporator, condenser, and regenerator are connected by pipes, and the connecting pipes and bypass pipes are all equipped with insulation layers.
9. The ORC power generation skid from offshore platform waste heat according to any one of claims 1-5, characterized in that, The evaporator and condenser use shell-and-tube heat exchangers, while the preheater uses a plate heat exchanger.
10. An ORC waste heat power generation skid system, characterized in that, The offshore platform ORC waste heat power generation skid unit as described in any one of claims 1-9 was used.
