During the peak power consumption period, the primary fuel gas and the secondary fuel gas are fully combusted in the fuel cell station 5 to generate water vapor to drive the steam turbine to work and generate power.

[0050] The specific working process is as follows:

[0051] During the day, the solar energy light tower 1 absorbs solar energy through the heat absorber and generates heat. The solid waste is first sent into the pretreatment chamber 7, the heat absorber supplies heat to the pretreatment chamber 7 to generate a preheating temperature of 100-200 DEG C, evaporates the moisture in the solid waste, and the solid waste is dried. The dried solid waste is transported into the gasification furnace 2 through the first crawler transport device.

[0052] The heat absorber supplies heat to the gasification furnace 2, and the gasification furnace 2 pyrolyzes the solid waste at a temperature of 500 DEG C, the stirring device 202 is used to ensure the uniformity of pyrolysis during the pyrolysis process, the pyrolysis time is about 1 hour, and the pyrolyzed solid waste becomes primary fuel gas, hot fuel oil and pyrolysis coke, wherein the primary fuel gas is in the uppermost layer, the hot fuel oil is in the middle layer, and the pyrolysis coke is in the lowermost layer. The primary fuel gas is directly collected into the gas storage tank 3 through the first gas collecting pipeline 8, the hot fuel oil and the pyrolysis coke are collected into the oil storage tank 10 and the pyrolysis coke storage room 9 respectively, and the primary fuel gas, the hot fuel oil and the pyrolysis coke still have a temperature of above 400 DEG C during the process of being transported to the corresponding collecting device. The heat collecting end of the heat collecting mechanism 14 collects the heat of the primary fuel gas, the hot fuel oil and the pyrolysis coke by heat exchange.

[0053] At night, the power consumption is greatly reduced, and the thermal power generator set 6 is forced to reduce the load. In order to ensure that the thermal power generator set 6 maintains a safe load, the hot fuel oil and the pyrolysis coke are mixed without limitation of the mixing ratio, the mixed hot fuel oil and pyrolysis coke are placed into the microwave pyrolysis equipment 4, the redundant power of the thermal power generator set 6 is supplied to the microwave pyrolysis equipment 4, the hot fuel oil and the pyrolysis coke are pyrolyzed at a temperature of 1000 DEG C, and the pyrolysis time is about 0.5 hours.

The temperature of the secondary fuel gas still has a temperature of 900 DEG C or above, and the heat collecting end of the heat collecting mechanism 14 collects the heat of the secondary fuel gas through heat exchange.

[0054] During the peak power consumption period, the fuel gas is delivered to the fuel cell station 5 through the gas storage tank 3 to generate power, reduce the load of the thermal power generator set, and realize the function of valley power peak shaving.

[0055] In the above process, when the light intensity is sufficient, the heat collecting mechanism 14 does not need to supply heat to the gasification furnace 2 or the pretreatment chamber 7; when the light intensity is insufficient, the heat collecting mechanism 14 supplies heat to the gasification furnace 2 or the pretreatment chamber 7 to maintain the pyrolysis function of the gasification furnace 2 and the preheating and drying function of the pretreatment chamber 7, and fully utilize the heat storage energy of the heat collecting mechanism 14 and the heat storage energy generated by the solar tower 1.

Compared with the traditional one-time microwave pyrolysis method, the application not only shortens the pyrolysis time, but also reduces the pyrolysis energy consumption.
