The method comprises the steps of converting redundant electric power into liquid oxygen, drying broken solid waste materials, pyrolysis oil and other high-energy-carrying materials, and when a wind-solar power station stops running, gasifying and blowing organic solid waste and liquid oxygen into an iron melting bath gasification furnace 301 to generate synthetic gas and convert the synthetic gas into hydrogen, wherein the synthetic gas and the hydrogen are used for gas turbine power generation, internal combustion engine power generation and fuel cell power generation, so that the external network is permanently and stably powered, and the technical scheme that the annual power supply time reaches 7000-8000 hours is realized. The method comprises the following steps:
As shown in fig. 1 and 2, the wind power photovoltaic coupling liquid oxygen molten iron bath gasification gas energy storage power generation system is applied to an energy storage type integrated power generation system with peak clipping and valley filling, and comprises a wind power photovoltaic integrated power station 101, a molten iron bath pure oxygen gasification system and a gas power generation unit;
The wind power and photovoltaic integrated power station 101 is connected to a public power grid 105 to supply power to the outside, and meanwhile internal power supply is performed through an internal power supply dispatching station 104;
In this embodiment, electricity generated by the wind-electricity photovoltaic integrated power station 101 is connected to the power distribution station 102, and the power distribution station 102 is connected to the inner power supply dispatching station 104 and the outer power supply dispatching station 103 respectively through dispatching by the power distribution station 102, the outer power supply dispatching station 103 is connected to the public power grid 105 for externally supplying power, and the inner power supply dispatching station 104 is used for internally supplying power, so as to preferentially ensure that the cryogenic air separation unit 201 produces liquid oxygen and the molten iron bath pure oxygen gasification system produces synthetic gas and the like.
The internal power supply dispatching station 104 is respectively connected with a cryogenic air separation unit 201, a material crushing unit 202, an electrothermal drying baking furnace 203 and a pyrolysis furnace 204.
As shown in fig. 3 and fig. 4, when sufficient wind and light resources exist, the redundant power of the wind and photovoltaic comprehensive power station 101 is utilized to start the cryogenic air separation unit 201, the material crushing unit 202, the electric heating drying baking furnace 203 and the pyrolysis furnace 204 to store energy sources as required; as shown in fig. 5 and 6, when there is no wind-light resource, the pure oxygen gasification system of the molten iron bath is started as required to produce synthetic gas by using the reserve energy source, and the synthetic gas is used for generating electricity.
The cryogenic air separation unit 201 is used for preparing liquid oxygen by using surplus green electricity and storing the liquid oxygen in the liquid oxygen storage tank 210 when sufficient wind and light resources exist, and inputting the oxygen with pressure into the molten iron bath gasifier 301 to be used as a gasifying agent by gasifying the liquid oxygen in the liquid oxygen storage tank 210 when no wind and light resources exist. The pressurized oxygen is heated before being input into the molten iron bath gasifier 301, and then is generated by the first gas turbine generator set 216, and the electricity generated by the first gas turbine generator set 216 is input into the public power grid 105 through the external power supply dispatching station 103.
In this embodiment, the outlet of the liquid oxygen storage tank 210 is connected with a liquid oxygen valve 211, the opening and closing of a pipeline is controlled by the liquid oxygen valve 211, when the liquid oxygen is required to be gasified, the liquid oxygen is opened, the liquid oxygen is sequentially pressurized by a liquid oxygen booster pump 212, gasified and heat exchanged by a first air heat exchange vaporizer, heated by a first primary heater 214 (a heat source is from medium-temperature waste heat 340 recovered by a gas power generation unit), heated by a first secondary heater 215 (a heat source is from high-temperature waste heat 345 recovered by the gas power generation unit), the enthalpy value is increased, then the first gas turbine generator unit 216 generates electricity, oxygen is temporarily stored by the high-pressure oxygen storage tank 302, and the oxygen can be immediately supplied to the molten iron bath gasifier 301 as a gasifying agent when no wind light resource exists. Because the volume and the preservation cost of the liquid oxygen are far lower than those of the oxygen, the liquid oxygen storage adopted before the process can obviously reduce the cost, and can store a plurality of liquid oxygen, and then the liquid oxygen is used for generating electricity when the oxygen is needed, so that the generating capacity and the energy utilization rate are improved.

The outlet of the liquid nitrogen storage tank 220 is connected with a liquid nitrogen valve 221 in the same way as liquid oxygen gasification, the opening and closing of a pipeline are controlled through the liquid nitrogen valve 221, when liquid nitrogen is required to be gasified, the liquid nitrogen valve 221 is opened, the liquid nitrogen is sequentially pressurized through a liquid nitrogen booster pump 222, gasified and heat-exchanged by a second air heat-exchanging gasifier 223, the temperature of the second primary heater 224 is raised (heat source comes from medium-temperature waste heat 340 recovered by a gas power generation unit), the temperature of the second secondary heater 225 is raised (heat source comes from high-temperature waste heat 345 recovered by the gas power generation unit), the enthalpy value is increased, then the second gas turbine generator unit 217 generates power, oxygen is temporarily stored through the high-pressure oxygen storage tank 302, and the oxygen can be immediately supplied to the molten iron bath gasifier 301 to be used as a gasifying agent when no wind light resource exists. Because the air is deeply cooled and separated to produce liquid oxygen and simultaneously generate a part of liquid nitrogen, the liquid nitrogen storage is adopted, so that the storage of the liquid nitrogen can be increased, and then the electricity is generated along the way according to the requirement, so that the electricity generation capacity and the energy utilization rate are improved.
Preferably, as shown in fig. 7, in order to further improve the energy utilization rate, the organic solid waste is crushed, and the low-temperature crushing system is further included, wherein the low-temperature crushing system comprises a liquid nitrogen storage tank 220, a liquid nitrogen valve 221, a liquid nitrogen booster pump 222, a liquid nitrogen crusher 403, a low-temperature nitrogen crusher 401, a dust remover 402, a second air heat exchanger vaporizer 223, a second primary heater 224, a second secondary heater 225, a second gas turbine generator unit 217 and a high-pressure nitrogen buffer tank 330 which are sequentially arranged, and the crushed material parts of low-temperature liquid nitrogen and low-temperature nitrogen are used as gasification raw materials of the molten iron bath gasifier 301. If the waste rubber and the waste tire are separated from the solid waste, the waste rubber and the waste tire sequentially pass through a low-temperature nitrogen pulverizer 401 and a liquid nitrogen pulverizer 403 to obtain the rubber superfine powder for comprehensive utilization.
