Detailed Description
The following detailed description of the embodiments of the utility model, given by way of example only, is presented in the accompanying drawings to aid in a more complete, accurate, and thorough understanding of the inventive concepts and aspects of the utility model by those skilled in the art.
Example 1:
as shown in fig. 1, the utility model provides the circulating power generation device adopting the steam turbine, which comprises a gas turbine 2, a steam turbine 4, a main generator 3 driven by the gas turbine 2 and a steam turbine generator 7 driven by the steam turbine 4, and further comprises a blower 6, an air compressor 5, a waste heat boiler 8, a steam drum 9, a mixer 10, a superheater 11, a waterway system, a steam-water heat exchanger 13 and a steam-water heat exchanger 12. The steam-water heat exchanger 13 is used for heat exchange between steam and water, and the gas-steam heat exchanger 12 is used for heat exchange between steam and gas.
An air inlet of the air compressor 5 is connected with an air outlet of the air inlet machine 6, and air is fed by the air inlet machine 6. The air compressor 5 and the air inlet machine 6 are also driven by the steam turbine 4, so that the electricity consumption of the generator set is reduced, and the energy conversion efficiency is improved. The high pressure air provided by the air compressor 5 can raise the air pressure in the gas turbine 2 and the steam turbine 4 and provide combustion gas to the gas turbine 2. The gas inlet device 1 supplies gas through a gas inlet of the gas turbine 2.
The exhaust-heat boiler 8 has its inlet connected to the gas outlet of the gas turbine 2, its inlet connected to the waterway system, its flue gas discharge pipe connected to the exhaust gas discharge device of the power generation system, its steam outlet connected to the inlet of the drum 9, and its outlet connected to the recovery line of the waterway system.
The waterway system comprises a cooling system 14 and a water supply system 15, wherein the water supply system 15 comprises a water tank provided with a booster water pump, a water temperature detector is arranged in the water tank, the water tank is connected with a water supply pipeline, a water supplementing pipeline and a recovery pipeline, the water outlet of the water tank is the water outlet of the water supply system 15, the water inlet of the recovery pipeline is respectively connected to a water outlet of the waste heat boiler 8 and a water outlet of the steam turbine 4, and the water inlet of the water supplementing pipeline is connected to an external water source.
The cooling system 14 comprises a condenser, an evaporator and a cooling pipeline for cooling each device, the air inlet of the water path system is the air inlet of the condenser, the water outlet of the condenser is connected to the cooling pipeline through the evaporator, the backwater part of the cooling pipeline is connected to the water inlet of a water tank in the water supply system 15 through the water supply pipeline, and the water outlet of the water supply system 15 is connected to the water inlet of the waste heat boiler 8 through the water outlet pipeline. The waste heat boiler 8 converts water provided by the water supply system 15 into high-temperature steam by utilizing heat in high-temperature flue gas generated by the gas turbine 2, and provides a working medium for the steam turbine 4.
The steam drum 9 is provided with a steam-water separator inside in addition to the air inlet connected to the air outlet of said waste heat boiler 8, so that its air outlet is connected to the first air inlet of the mixer 10 and its water outlet is connected to the recovery line. The recovery pipeline can be a plurality of pipelines which are mutually independent and are connected with the water tank, and can also be a pipeline structure provided with a plurality of water inlet branch pipes and a water inlet main pipe. The air outlet of the air compressor 5 is connected to a gas-steam heat exchanger 12, and the gas-steam heat exchanger 12 is connected to the second air inlet of the mixer 10 and the air inlet of the gas turbine 2 through branch pipes. The mixer 10 thus mixes the high-pressure air with the high-temperature saturated steam supplied from the drum 9 and then further heats the mixture to obtain superheated steam by passing the mixture through the air outlet of the mixer 10 to a superheater 11 connected thereto.
The gas outlet of the superheater 11 is connected with the gas inlet of the steam turbine 4 to convey superheated steam, and the superheated steam is used for generating power through the operation of the superheated steam, so that the water content is low, the pressure is high, the power generation efficiency is enhanced, and the service life is prolonged. The steam exiting the outlet of the steam turbine 4 has a higher heat content, so that the heat is recovered further by the circulation system. The air outlet is connected to the air inlet of the waterway system through a heat supply pipeline of the air-steam heat exchanger 12 and a heat supply pipeline of the steam-water heat exchanger 13, and the heated pipelines of the air-steam heat exchanger 12 and the steam-water heat exchanger 13 are respectively connected with the air outlet pipeline of the air compressor 5 and the water supply pipeline of the waterway system. Therefore, the heat exchange of the high-pressure gas and the water supply pipeline can greatly improve the heat recovery efficiency and the energy conversion efficiency of the power generation device.
The water supply system 15 utilizes the water heated by the backwater part of the cooling system 14, and the condensate water generated by the recovery steam drum 9, the steam turbine 4 and the waste heat boiler 8 to further recover heat, so that the water supplied to the waste heat boiler 8 is higher in temperature and is easier to be converted into steam, and the energy utilization efficiency is improved. Since the high-pressure air supply is used to supply air to the mixer 10 and the gas turbine 2 and the exhaust steam is used to preheat the air, the power generation efficiency of the gas turbine 2 and the steam turbine 4 can be effectively improved, and energy can be saved.
Example 2:
as shown in fig. 2, the present embodiment differs from embodiment 1 in that the flue gas discharged from the gas turbine 2 is further processed. The flue gas discharge pipe of the waste heat boiler 8 is connected to the waste gas purification system 16 through a heating pipeline of the gas-water heat exchanger 17, and the water outlet of the water supply system 15 is connected to the water inlet of the waste heat boiler 8 through a heated pipeline of the gas-water heat exchanger 17. The flue gas discharged after heat is absorbed by the waste heat boiler 8 still has a certain temperature, so that the water outlet pipeline for supplying water to the waste heat boiler 8 by the water supply system 15 can be further heated, and the gas-water heat exchanger 17 is used for exchanging heat between the high-temperature flue gas and water. This is more advantageous in that the efficiency of steam generation is improved, the heat in the flue gas is recovered, and the flue gas discharged from the gas-water heat exchanger 17 is conveyed to the exhaust gas purification system 16 for purification to reduce pollution, because some harmful gases are also in the flue gas.
