The other end of the gas pipe 6 is communicated with a combustion chamber 7 of the gas turbine. The 16 groups of atomizing nozzles 19 are uniformly connected into the gas pipe 6 along the circumferential direction of the gas pipe 6.

It is understood that the ring pipes 13 of the present invention may be connected to 6, 10, 20 or more water spray pipes 14 according to the thickness of the gas pipes 6, the pressure of the desalted water, and the site conditions. Of course, only 1 group of water spraying pipes 14 can be communicated, and when the water conveying pipe 12 is communicated with only 1 group of water spraying pipes 14, the annular pipe 13 does not need to be arranged. The number of sprinkler pipes 14 is not limited by the present invention. The dust remover 3, the coal press 4 and the gas cooler 5 can be selectively arranged or not arranged according to factors such as the conveying length of the gas pipe 6, the powder impurity content of the gas, the concentration of the gas and the like. Of course, corresponding structures such as control valves for controlling the gas flow and pressure can be arranged according to the conveying requirements.

As shown in fig. 1 and 2, the water pipe 12 is provided with a flow control valve 10 and an isolation valve 11. The flow control valve 10 is provided at one end of the feed water main near the boiler 1 to control the flow of the demineralized water. The isolating valve 11 is arranged at one end close to the gas pipe 6 and is used for preventing gas from flowing backwards into the water conveying pipe 12. Wherein the number of isolation valves 11 is 3 groups. Of course, more sets of isolation valves 11 may be provided according to the length of the actual water pipe 12.

As shown in fig. 2, the ring pipe 13 has an octagonal ring structure, and the ring pipe 13 surrounds the outer circumference of the gas pipe 6. Every 2 groups of spray pipes 14 in 16 groups of spray pipes 14 are respectively arranged on the same side of the octagonal

annular pipe

13, 2 groups of atomizing spray heads 19 are distributed at intervals along the length direction of the

gas pipe

6, 2 groups of atomizing spray heads 19 are distributed at intervals along the circumferential direction of the gas pipe 6, so that 16 groups of atomizing spray heads 19 are arranged on the gas pipe 6 in a quincunx shape, atomized demineralized water can be uniformly and hierarchically sprayed to the gas pipe 6, and the atomized demineralized water is fully mixed with gas.

It is understood that the shape of the circular pipe 13 is designed according to the number of the water spray pipes 14, and when the number of the water spray pipes 14 is small, the circular pipe 13 can also be designed to be triangular, quadrangular or hexagonal; when the number of the water spray pipes 14 is large, the ring pipe 13 may be formed in a decagon shape, a dodecagon shape, or a tetradecagon shape. The arrangement of the atomizer nozzles 19 on the gas pipe 6 can also be set to a larger number of layers depending on the actual number.

As shown in fig. 2, the water spray pipe 14 is connected between the ring pipe 13 and the gas pipe 6 in a zigzag structure. Of course, the water spraying pipe 14 can be designed to be C-shaped, L-shaped or I-shaped according to the distance between the annular pipe 13 and the atomizing nozzle 19. The annular pipe 13 is connected with the annular pipe 13 through a flange, the annular pipe 13 is connected with the spray pipe 14 through a flange, and the annular pipe 13 and the spray pipe 14 can be conveniently mounted and dismounted. To increase the stability of the annular tube 13, a holder for supporting the annular tube 13 is attached to the annular tube 13. The structural form of the support includes, but is not limited to, a pull rod arranged on the gas pipe 6 or a support frame arranged on the ground.

As shown in fig. 3, the spray pipe 14 is connected with a first flange 15 at one end of the atomizer 19, the gas pipe 6 is provided with a hole for installing the atomizer 19, a bridge pipe 20 is welded at the hole, and the bridge pipe 20 is connected with a second flange 16. The atomizing nozzle 19 has a tubular body 17, and a stopper plate 18 is provided on the tubular body 17, and the diameter of the stopper plate 18 is the same as the diameter of the first flange 15 and the second flange 16. The first flange 15 and the second flange 16 are fixed by bolts, and the atomizer 19 is connected between the first flange 15 and the second flange 16 by the limiting disc 18 through threads, so that the atomizer 19 keeps a relatively fixed position. The demineralized water in the spray pipe 14 is input into the atomizing nozzle 19 through the pipe body 17, and the atomizing nozzle 19 extends into the gas pipe 6, so that the atomized demineralized water and the gas are fully mixed. Of course, the atomizer 19 can also be connected to the spray pipe 14 by welding or interference-connecting the pipe body 17 to the spray pipe 14.

When the atmospheric density is reduced, especially in summer, the high-pressure demineralized water in the feeding mother pipe of the boiler 1 is input into the atomizing nozzle 19 through the water conveying pipe 12, the annular pipe 13 and the water spraying pipe 14. The atomizing nozzle 19 atomizes the demineralized water and then sprays the atomized demineralized water into the gas pipe 6, so that the atomized demineralized water and the gas are fully mixed and then are conveyed to the combustion chamber 7 of the gas turbine through the gas pipe 6. Meanwhile, the air compressor 8 inputs air into the combustion chamber 7, and the air and the coal gas are combusted to do work on a combustion turbine 9 of the gas turbine.

Normally, the air flow in the combustion chamber 7 is larger than the gas flow. When the atmospheric density decreases, the amount of air decreases, resulting in a relatively high amount of gas. At this time, if the air and the gas continue to be combusted, the combustion temperature exceeds the upper temperature limit set by the combustion chamber 7, and only the input gas amount of the gas can be reduced. On the one hand, a reduction in the air-fuel ratio leads to a reduction in the ventilation of the combustion turbine 9, which reduces the output of the gas turbine. On the other hand, the upper temperature limit of the combustion chamber 7 limits the output of the gas turbine.

The invention absorbs heat through the vaporization of the desalted water, can reduce the temperature of the coal gas, and reduces the temperature of the combustion of the air and the coal gas in the combustion chamber 7. On one hand, the temperature in the combustion chamber 7 is prevented from breaking through the upper temperature limit, and on the other hand, the input gas quantity of coal gas is not required to be reduced. Meanwhile, the desalted water is vaporized and contributes to the extra work of the combustion turbine 9 of the gas turbine, so that the output of the gas turbine unit in summer is greatly improved.

The invention fully utilizes the residual amount and high pressure of the demineralized water in the water supply main pipe of the boiler 1 by introducing the demineralized water in the water supply main pipe of the boiler 1, and avoids the problems of large energy consumption and high equipment purchase and maintenance cost caused by additionally arranging water supply pumps and other equipment. Meanwhile, the coal gas in the by-product of the blast furnace 2 is introduced, so that the coal gas resource produced by the blast furnace 2 is fully utilized, and the dispersion of the coal gas to the atmosphere is reduced. The problem that the load of the gas turbine is limited at high temperature in summer is solved, the advantage conditions of the iron and steel enterprise are combined, the existing energy of the iron and steel enterprise is fully utilized, and meanwhile, the environmental pollution is avoided.

Example 2:

the invention also provides a CCPP (combined cycle control protocol), which comprises a boiler 1, a steam turbine, a gas turbine and a load enhancement device of the gas turbine. Wherein, boiler 1 adopts exhaust-heat boiler, and the main pipe of giving water of boiler 1 is carried the demineralized water of atomizing to gas pipe 6 through atomizer 19. The gas pipe 6 is used for introducing gas generated by the blast furnace 2, and a dust remover 3 and a coal press 4 are respectively arranged between the gas pipe 6 and the blast furnace 2 and used for removing dust and pressure feeding of the gas generated by the blast furnace 2. A gas cooler 5 is connected between the input port of the dust remover 3 and the output port of the coal press 4 and is used for the backflow of the gas. The waste gas delivery outlet of gas turbine is connected with the waste gas input port of boiler 1 through wear-resisting high temperature resistant pipeline, and the steam delivery outlet of boiler 1 is connected with the steam input port of steam turbine through high temperature resistant pipeline.

The invention introduces the coal gas generated by the blast furnace 2 into the gas turbine as fuel, fully utilizes the coal gas resource of iron and steel enterprises, and avoids the coal gas from diffusing into the air. After the coal gas and the air are combusted, the coal gas and the air do work on a turbine of the gas turbine, so that the gas turbine inputs power to the generator set. Meanwhile, high-temperature exhaust gas generated by the gas turbine is conveyed to the boiler 1 through a wear-resistant and high-temperature-resistant pipeline, so that high-temperature steam is generated in the boiler 1. And high-temperature steam is conveyed to the steam turbine through a high-temperature-resistant pipeline, so that the steam turbine inputs power to the generator set. In the whole process, the gas turbine and the steam turbine are driven to simultaneously output power to the generator set, the coal gas of the blast furnace 2 and the waste gas of the gas turbine are fully utilized, and the environment is protected.

Example 3:

the present invention also provides a method for load enhancement of a gas turbine, as shown in fig. 4, using the load enhancement device for a gas turbine. The coal gas produced by the blast furnace 2 is input into a coal gas pipe 6 after the process steps of dust removal, cooling and the like. The demineralized water in the water supply main pipe of the boiler 1 is introduced into the water spraying pipe 14 through the water conveying pipe 12, and the demineralized water is sprayed into the gas pipe 6 after being atomized by the atomizing nozzle 19. The atomized demineralized water and the coal gas are fully mixed in the coal gas pipe 6 and then are conveyed to a combustion chamber 7 of the gas turbine. Air is input into the combustion chamber 7 through an air compressor 8, and the coal gas and the air do work on a combustion turbine 9 of the gas turbine after being combusted in the combustion chamber 7.

For example, normally, the air volume input by the air compressor 8 is 3 ten thousand square, the gas volume input by the coal press 4 is 1 ten thousand square, and the temperature of the combustion of the air and the gas in the combustion chamber 7 is 1200 ℃. In summer, when the temperature is high, the air compressor 8 can only input 2.5 ten thousand square gas flows under the rated power, and the gas flow of the coal gas is relatively high. If the combustion continues to cause the temperature of the combustion chamber 7 to exceed 1200 ℃, the gas input of the gas needs to be reduced to 0.8 ten thousand square. This results in a reduced ventilation of the air and gas combustion, which results in a reduced unit load of the gas turbine.

By inputting atomized demineralized water into the coal gas, the demineralized water is vaporized and absorbs heat when the air and the coal gas are combusted, so that the combustion temperature can be effectively reduced, and the temperature of the combustion chamber 7 is lower than 1200 ℃. At the moment, the gas input of the coal gas can be maintained at least at 1 ten thousand square, and can even be continuously improved. The ventilation of the combustion turbine 9 is increased, so that the unit load of the gas turbine is increased. In addition, the evaporated demineralized water also contributes to the ventilation of the combustion turbine 9, further increasing the unit load of the gas turbine in summer.

According to the invention, the boiler 1, the blast furnace 2 and the gas turbine are connected through the pipeline, and residual resources of the boiler 1 and the blast furnace 2 are fully utilized for recycling the gas turbine, so that the unit load of the gas turbine under the working condition of high temperature and low pressure in summer is effectively improved. Meanwhile, the waste of the demineralized water allowance of the boiler 1 is avoided, and the coal gas of the blast furnace 2 is prevented from being emitted to the atmosphere. The production capacity is improved, the environment is protected, and the purposes of energy conservation and emission reduction are achieved.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
