Description
Technical Field
The invention belongs to the technical field of gas turbine application, and particularly relates to a gas turbine circulating system for deeply dehumidifying air intake by using waste heat and a dehumidifying method thereof.
Background
The gas turbine as a novel power machine consists of a gas compressor, a combustion chamber and a gas turbine, and has the advantages of small volume, low investment and quick start. Gas turbines have been widely used in the aerospace and marine fields, and are currently rapidly developing into a variety of fields such as power, petrochemistry, metallurgy, and transportation. China is wide in territory, spans a plurality of climatic zones such as tropical monsoon, subtropical monsoon, humid monsoon and the like, and many regions are humid and rainy and have high air moisture content. Humid air has a considerable influence on the operating performance of gas turbines, and is increasingly attracting attention, particularly in the field of sea. Through experimental analysis, the influence of air humidity on the gas turbine has the following aspects: firstly, the blade of the air compressor is easily damaged due to the increase of air humidity, and the energy consumption of the air compressor is increased; secondly, the combustion stability of the combustion chamber is easily deteriorated due to the increase of the air humidity; third, the increased air humidity increases the power of the gas turbine, but the relative internal efficiency of the gas turbine decreases. Therefore, the deep dehumidification of the inlet air of the gas turbine in advance has very important significance for improving the working performance of the gas turbine in a humid environment.
The dehumidification method commonly used in the industrial field at present is a condensation dehumidification method based on compression refrigeration, and the method needs to consume a large amount of high-grade electric energy, is not suitable for occasions with overhigh or overlow environmental temperature, and is troublesome to maintain. In view of the shortcomings and drawbacks of the conventional condensation dehumidification method, there is a need for a more efficient and energy-saving dehumidification method to improve the energy efficiency of the deep dehumidification process of the gas turbine inlet air. The solution dehumidification method utilizes the moisture absorption characteristic of the concentrated salt solution, does not need low refrigeration temperature compared with the condensation dehumidification method, and has great energy-saving potential. However, the existing solution dehumidification method still utilizes high-grade power to meet the low-grade dehumidification requirement and does not meet the cascade utilization of energy. By combining the above analysis, the exhaust waste heat of the gas turbine can be considered as the only driving energy for solution dehumidification to carry out waste heat recovery, and then the solution dehumidification method is used for deeply dehumidifying the intake air of the gas turbine, so that the heat efficiency of the gas turbine circulation system is improved, and the working performance of the gas turbine in a humid environment is improved.
Disclosure of Invention

Another object of the present invention is to provide a method for utilizing the residual heat of a gas turbine for deep dehumidification of intake air, which has low energy consumption and strong dehumidification capability.
The purpose of the invention is realized by the following technical scheme:
the invention relates to a gas turbine circulating system using waste heat for deep dehumidification of inlet air, which comprises a primary solution dehumidifier, a secondary solution dehumidifier, a gas turbine, a smoke type absorption refrigerator, a regenerative heater, a regenerator, a circulating pump, a primary water-cooled cooler, a secondary water-cooled cooler, a fresh air pipeline, a wind stroke pipeline, an air supply pipeline, a smoke pipeline, a concentrated solution pipeline, an intermediate solution pipeline, a dilute solution pipeline and a regenerative air pipeline.

2) The flue gas discharged by the gas turbine of the gas turbine firstly goes to the flue gas type absorption refrigerator as a driving heat source of the flue gas type absorption refrigerator, then goes to the regenerative heater for further releasing heat and then is discharged to the outside.
3) The concentrated solution of the regenerator is driven by a circulating pump, is cooled by a primary water-cooled cooler and then enters a primary solution dehumidifier, and after the concentrated solution in the primary solution dehumidifier absorbs moisture in humid air, the concentration of the concentrated solution is reduced and the concentrated solution is converted into an intermediate solution; the intermediate solution is firstly cooled for the first time by the two-stage water-cooled cooler and then enters the flue gas type absorption refrigerator for cooling for the second time to form a low-temperature intermediate solution, so that the solution dehumidification capacity is improved. The low-temperature intermediate solution enters a secondary solution dehumidifier to contact primary dehumidified air from a primary solution dehumidifier, and the concentration of the low-temperature intermediate solution is reduced after the low-temperature intermediate solution absorbs moisture in the primary dehumidified air, so that the low-temperature intermediate solution is converted into a dilute solution; the dilute solution firstly enters a regenerative heater to be heated to the regeneration temperature, then enters a regenerator to be contacted with regeneration air, moisture is transferred from the solution side to the air side, the dilute solution is converted into the concentrated solution, and a working medium cycle is completed.
After the scheme is adopted, the invention has the following advantages:

And secondly, the thermal efficiency of the gas turbine cycle is improved. The gas turbine of the gas turbine is respectively connected with the smoke absorption type refrigerating machine and the regenerative heater through pipelines to provide heat energy, the smoke absorption type refrigerating machine is used for recovering waste heat of high-temperature smoke discharged by the gas turbine, and the regenerative heater is used for further recovering low-temperature heat energy of the smoke, so that the heat efficiency and the fuel utilization coefficient of the gas turbine are greatly improved.
And thirdly, energy consumption in the dehumidification process is reduced. Because the invention is provided with the primary solution dehumidifier and the secondary solution dehumidifier, the traditional condensation dehumidification method is replaced by the two-stage solution dehumidification method, the dehumidification capacity is greatly enhanced, the energy consumption in the dehumidification process is reduced, the exhaust waste heat of the gas turbine is completely adopted as the only energy source for solution dehumidification, and the problem that the solution dehumidification method depends on high-grade electric energy is solved.
Fourthly, the application range is wide. The wet area of China occupies about one third of the area of the soil and the area of a wide sea area, and a huge space is provided for the application of the invention; in addition, the dehumidification method only depends on the waste heat of the gas turbine, does not need electric power or other external energy sources, and is suitable for more special occasions.
