Description
Technical Field
The utility model relates to a gas turbine sea water heat exchanger field, concretely relates to intercooling circulation marine gas turbine sea water heat exchanger based on constant temperature mixing system.
Background
The gas turbine is a typical conventional fuel power device, has the characteristics of small volume, high power, light weight, quick start and the like, and is widely applied to the industrial core fields of aviation, electric power, ships, natural gas transmission and the like. The intercooling cycle gas turbine optimizes the thermodynamic cycle mode by adding the intercooler on the basis of the simple cycle gas turbine, can reduce the temperature of air entering the high-pressure compressor, reduces the power consumption of the high-pressure compressor, improves the power by the simplest technical approach with the minimum change, and quickly obtains the optimal means of a type of high-power gas turbine. The seawater heat exchanger is a core component of an external circulation heat exchange system of the indirect cooling circulation gas turbine, and is used for taking away heat of high-temperature fresh water in internal circulation by using low-temperature seawater and finally playing a role in reducing the air temperature behind the low-pressure gas compressor. In general, no special requirement is made on the inlet temperature of the seawater heat exchanger. However, in the development stage of the marine gas turbine, the inlet temperature needs to be controlled to a fixed value, such as 27 ℃ specified by the naval conditions in China or 32 ℃ specified by the naval conditions in the United states, so as to better test the real performance of the marine gas turbine in the standard marine environment. Therefore, a special constant-temperature blending system is required to be designed for the gas turbine seawater heat exchanger for the intercooling cycle ship.
The research on the gas turbine for the intercooling cycle ship mainly focuses on the following aspects: the model development of the gas turbine for the intercooling cycle ship is realized, for example, WR-21 type gas turbines are jointly developed by Rollse-Royce company, AlliedSignal company and CAE electronic company designated by the US naval; the European Union multination develops a new concept high pressure ratio intercooling aero-engine under the 6 th frame; the GE company has developed LMS-100, etc., which is an indirect cooling type heavy gas turbine, in conjunction with Volvo aircraft engine, Sweden, Avion, Italy, and Sumitomo, Japan. Secondly, optimizing, analyzing and researching the performance of the gas turbine for the intercooling cycle ship, such as R.C.Wilcock and the like, which proves that the influence of the improvement of the turbine inlet temperature on the performance of the intercooling cycle gas turbine is provided; liushuron et al analyzed ICR cycle population and system and analyzed ICR gas turbine variable behavior using a high order deviation method. Thirdly, researching the simulation technology of the complete machine or key components of the gas turbine for the intercooling cycle ship, wherein a simulation model of the intercooling cycle gas turbine is established on a Matlab/Simulink simulation platform by adopting a volumetric inertia method by using a Luoping method; the Wang construction request adopts an object-oriented modular modeling method to establish a simulation model of the indirect cooling circulation gas turbine, and contrasts and analyzes the operating characteristics under different indirect cooling conditions; wen Chazhu et al developed an intercooler design program, and can design and analyze the distribution and variation trend of parameters such as temperature, pressure, speed, local heat transfer coefficient and the like of a plurality of sections of an intercooler; in Huangyu, simulation models of the simple cycle gas turbine and the intercooling regenerative cycle gas turbine are established based on an Easy5 simulation platform, steady-state characteristic analysis is respectively carried out on the simulation models, the simulation models are compared under two cycle modes, finally, dynamic characteristic research is carried out on the intercooling regenerative gas turbine, and control strategy exploration is carried out on the gas turbine under different cycle modes preliminarily. Although a great deal of research has been carried out by domestic and foreign scholars and enterprises, no design work for a constant temperature mixing system of a seawater heat exchanger exists from the public data.
The problem that the current indirect cooling circulation marine gas turbine seawater heat exchanger generally exists is that: the cooling capacity is changed along with the fluctuation of the sea water amount and the sea water temperature, and the inlet temperature of the sea water heat exchanger is not fixed, so that the real performance of the indirect cooling circulation marine gas turbine in the standard marine environment cannot be accurately tested. When key performance comparison is carried out on the gas turbines for the intercooling cycle ships of different models, the comparison calculation can only be carried out through a performance conversion method due to different ocean environment temperatures. However, for the indirect cooling cycle gas turbine, the performance conversion method is not mature and has no unified standard, so that the uncertain factors during performance comparison are too many, and the accuracy and the objective fairness of the comparison are influenced.
In summary, the cooling capacity of the existing seawater heat exchanger of the indirect cooling circulation marine gas turbine changes along with the fluctuation of the seawater volume and the seawater temperature, the inlet temperature of the seawater heat exchanger is not fixed, so that the real performance of the indirect cooling circulation marine gas turbine in the standard marine environment cannot be accurately tested, the critical performance of the indirect cooling circulation marine gas turbine of different models can be compared and calculated only by using the existing performance conversion algorithm, the calculated result is not unified to the standard to measure, and the accuracy and the objective fairness of comparison are influenced.
