The input medium in the invention is garbage, sludge, biomass and coal, and the output medium is electricity, steam, cold medium and heat medium.
The specific working process of the invention is as follows:
the garbage is treated by the garbage direct-fired coupling system 1, then is fed into the power station boiler 7 to be combusted, and simultaneously is fed into the garbage gasification furnace 2 to be treated, and is changed into gasification fuel which is then fed into the power station boiler 7 to be combusted. Coal, sludge and biomass are respectively treated by a pulverizing system 6, a sludge pre-drying system 5 and a biomass direct-fired coupling system 4 to become dry powder particles, and the dry powder particles are fully mixed to form blended fuel and then are sent into a power station boiler 7 for combustion. The biomass is processed by the biomass gasification furnace 3 to become gasification fuel, and then is fully mixed with the garbage gasification fuel, and then is sent to the electric station boiler 7 for combustion.
High-grade steam output by the utility boiler 7 enters a steam turbine 8 to do work so as to drive a generator 9 to generate electricity to generate electric energy, and exhaust gas after doing work is directly extracted from the steam turbine 8 after the grade is gradually reduced to a specific grade so as to be supplied to industrial steam equipment 19, absorption refrigeration equipment 21 and a heat exchanger 23 in a park for use.
The electrical energy generated by the generator 9 is, in part, directed to a utility grid 12 and, in part, to a utility grid 10. Electric energy is supplied to an air separation plant 16, an electrolytic hydrogen production plant 17 and a public gas preparation plant 18 in the park for use through a plant power grid 10 to obtain various gas products such as nitrogen, oxygen, hydrogen and the like; it can also be used for a compression refrigeration equipment 20 and a compression heat pump 22 in a park.
The distributed photovoltaic power generation system 11 is additionally arranged on the roof or the open space of a plant of a thermal power plant. When the illumination is stable, the electric energy generated by the distributed photovoltaic power generation system 11 is converted and directly supplied to the heavy truck power exchange station 14 and the automobile charging pile 15 for use, and the redundant electric energy is sent to the plant power grid 10; when the illumination is unstable, the electric energy generated by the distributed photovoltaic power generation system 11 preferentially enters the power storage station 13 for relay storage, and then is supplied to the heavy truck power conversion station 14 and the automobile charging pile 15 for use.
When the thermal power plant needs to carry out deep peak shaving, redundant electric energy generated by the generator 9 is sent to the power storage station 13 for relay storage through the plant power grid 10; when abnormal shutdown of the thermal power plant occurs, the power storage station 13 may temporarily supply electrical energy to the plant grid 10 and the utility grid 12.
The compression refrigeration equipment 20 and the absorption refrigeration equipment 21 can jointly produce cold media, and the cold media are supplied to the cold supply equipment 26 in the garden through a pipe network. The pipe network is provided with a cold storage device 24 as a buffer, and the balance of cold supply capacity and cold demand capacity in the park is ensured by adjusting the distribution of cold medium flow in the pipe network in real time.
The compression heat pump 22 and the heat exchanger 23 can jointly produce a heat medium. The heat medium is supplied to the heating facility 27 in the campus via the piping network. Set up heat-retaining device 25 in the pipe network as the buffering, through the hot medium flow distribution in the real-time regulation pipe network, guarantee the balance of garden heating capacity and heat demand.
The invention utilizes the original coal-fired unit of the thermal power plant to extract steam from the steam turbine to realize steam supply and heat supply, utilizes the steam as the heat source of the absorption heat pump to realize cold supply, and utilizes the advantage of low cost of plant power, thereby being capable of supplying power for a public gas production system, such as air separation, electrolytic hydrogen and the like to prepare the public gas used by the power plant or an industrial park. In addition, the original coal-fired power plant boiler is technically improved, a set of garbage and sludge coupling device is added to realize the treatment of garbage and sludge, a set of biomass coupling coal-fired system is added to realize the coupling disposal of biomass.
In addition, the invention utilizes the roof of the factory building of the original thermal power plant or the open space to arrange a set of distributed photovoltaic, the electricity generated by the distributed photovoltaic is used for storing energy and charging the electric pile, the original coal-fired unit participates in deep peak regulation, and can be combined with the energy storage device to assist the deep peak regulation, so that the economic benefit of the thermal power plant not only earns deep regulation subsidies, but also can be discharged by the energy storage system when the electricity price is high and charged by the energy storage system when the electricity price is low, thereby realizing more online benefits. A set of charging piles of the electric heavy truck are built on the open space of the power plant, so that all electric automobiles in the industrial park are charged, and the power consumption cost is reduced.
