Embodiment 1

[0014] Example 1: Please refer to figure 1 , A solar thermal and natural gas cold energy combined power generator power generation system, including a water supply tank 1, a solar thermal system 3, a preheater 5 and an ORC screw expansion power generator unit 6. The water supply tank 1 is connected to the water supply pump 2 The solar thermal system 3 is connected. The liquefied natural gas (LNG) integrated energy system uses a screw expander cold energy ORC power generation system, a turbo expander differential pressure power generation system, and a new technology that combines a solar thermal system. Use the effective space of its own area to arrange the solar thermal system, the water in the water supply tank 1 is fed into the solar thermal system 3 through the feed water pump 2, and the hot water generated by the system enters the organic working fluid evaporation system as the organic working fluid. The liquid becomes a vapor heat source for evaporation.

Embodiment 2

[0017] The second embodiment: on the basis of the first embodiment, the working fluid pump 9 is provided with multiple groups to facilitate the use of liquid supply. The feed water tank 1 is in communication with the evaporator 4 through a valve.

[0018] The invention is suitable for petroleum industry fields such as liquefied natural gas (LNG) receiving stations, oil fields, etc. It has certain infrastructure space, uses its own effective space to arrange solar thermal systems, collects solar clean energy, and converts solar clean energy from light energy. As heat energy, the hot water produced by the system enters the organic working fluid evaporation system as a heat source for the organic working fluid to change from liquid to vapor. The organic working fluid (ORC) screw expander power machine is used to convert heat energy into electric energy, and the exhausted steam after its work is used to cool the organic working fluid through the cold energy of liquefied natural gas (...

Abstract

The invention discloses a solar photo-thermal and natural gas cold energy combined power machine power generation system, and belongs to the field of power generation. The system comprises a water supply tank, a solar photo-thermal system, a preheater and an ORC screw rod expansion power machine generator set, wherein the water supply tank is connected with the solar photo-thermal system through awater supply pump, a liquid storage tank communicates with the preheater through a working medium pump, the preheater communicates with an evaporator, the evaporator communicates with the solar photo-thermal system, the evaporator communicates with the ORC screw rod expansion power machine generator set, and the ORC screw rod expansion power machine generator set communicates with a condenser. According to the solar photo-thermal and natural gas cold energy combined power machine power generation system, a comprehensive energy thermodynamic system is reasonable and scientific in heat energy,and efficient utilization is achieved; and in case of a disposing process, on the basis that LNG has the cold energy and pressure difference energy characteristics, the combination between a clean solar photo-thermal energy source and the cold energy and the pressure difference energy is adopted, so that the green and environment-friendly effects are achieved, the energy-saving concept is prominent, moreover, the life civilization environment of an LNG station is perfected, and the comprehensive energy utilization rate of the clean energy and the cold energy and the pressure difference energyis greatly improved.

Description

Technical field [0001] The invention relates to the field of power generation, in particular to a power generation system of a combined power machine of solar light heating and natural gas cold energy. Background technique [0002] Using liquefied natural gas (LNG)'s own cold energy, differential pressure energy, and solar energy in effective space, different characteristics of the surrounding environment of the region, according to the principle of localization, construct solar thermal systems and cooling in its effective space Energy and pressure difference can form a combined energy system, and the comprehensive energy (cold, heat, electricity) produced is all used for regional self-consumption, which greatly improves the civilized environment of LNG stations. Natural gas power generation has high thermal efficiency, and natural gas power generation has high thermal efficiency. At present, major companies have just launched or are developing "G" and "H" gas turbines. The init...
