Description
Technical field
The present invention relates to a kind of gas turbine, particularly relate to a kind of regenerative heat type electricity and drive the female pipe of multiple pressure mechanism of qi gas turbine.
Background technique
For existing close coupled type gas turbine, the driving force of its gas compressor is provided by turbine.Gas compressor, firing chamber, turbine integral body pass to power equipment or generator by coupling with air horsepower as power source.For ship power or generating, the operating mode of gas turbine also changes thereupon in the time of its load variations.And for the gas compressor in the gas turbine, its Study on Variable Condition Features is more violent, and efficient also decreases when low operating mode operation, and more easily surging phenomenon occurs.Simultaneously, at present existing practical application in existing gas turbine of recuperating device, but it is as an equipment independently, and function is too single.
Summary of the invention
The present invention can't keep the problem of higher operational efficiency in wider load variations scope in order to solve existing gas turbine, provide a kind of regenerative heat type electricity to drive the female pipe of multiple pressure mechanism of qi gas turbine, recuperating device and the female duct ligation of gas compressor air are closed, on the basis of the occupation of land of not increase system and investment, improved the air temperature behind the gas turbine group gas compressor, the fuel use amount reduces under identical power, and then has further improved the Economy of gas turbine group.
The technical solution used in the present invention is: a kind of regenerative heat type electricity drives the female pipe of multiple pressure mechanism of qi gas turbine, it is characterized in that comprising two groups of above gas compressors and exports female pipe, firing chamber, turbine and load; Each gas compressor input shaft is connected with respectively the gas compressor motor by coupling; Export female pipe be provided with air inlet, air outlet slit and smoke inlet be connected each gas compressor of smoke outlet air outlet slit respectively with the outlet female pipe air inlet be connected, the air outlet slit that exports female pipe is connected with the air inlet of firing chamber, the outlet of firing chamber is connected with the fuel gas inlet of turbine, and the output shaft of turbine is connected with load by coupling; The smoke outlet of turbine is connected with the smoke inlet of the female pipe of outlet.
Be provided with the air channel that hot good conductor is made between the air inlet of described cold female pipe and air outlet slit, be provided with outside the air channel and be provided with the housing that is connected with smoke outlet with smoke inlet outside the air channel.
The present invention closes recuperating device and the female duct ligation of gas compressor air, on the basis of the occupation of land of not increase system and investment, improved the air temperature behind the gas turbine group gas compressor, the fuel use amount reduces under identical power, and then further improved the Economy of gas turbine group, make existing gas turbine can in wider load variations scope, keep the high rate operation.

Specific embodiment
The embodiment of the invention as shown in Figure 1, this regenerative heat type electricity drives the female pipe of multiple pressure mechanism of qi gas turbine and is provided with two groups of gas compressors 3,4, the group number of its concrete gas compressor is unrestricted during enforcement can arrange according to actual needs, the present embodiment is minimum group several two groups; Also be provided with the female pipe 5 of outlet, firing chamber 6, turbine 7 and load 8; Each gas compressor 3,4 input shafts are connected with respectively gas compressor motor 1,2 by coupling; The female pipe 5 of outlet is provided with air inlet, air outlet slit and smoke inlet, smoke outlet; Each gas compressor 3,4 air outlet slit are connected with the air inlet of the female pipe 5 of outlet respectively, the air outlet slit of the female pipe 5 of outlet is connected with the air inlet of firing chamber 6, the outlet of firing chamber 6 is connected with the fuel gas inlet of turbine 7, the output shaft of turbine 7 is connected with load 8 by coupling, and load 8 is generator or propeller cavitation; Be provided with the air channel that hot good conductor is made between the air inlet of the female pipe 5 of outlet and air outlet slit, be provided with the housing that is connected with smoke outlet with smoke inlet outside the air channel, the smoke outlet of turbine 7 is connected with the smoke inlet of the female pipe 5 of outlet.The female pipe of backheat is a kind of heat exchanger with female pipe, and commonly used arriving is a kind of double-work medium surface-type heat exchanger in thermodynamic system.
Working procedure of the present invention is: its gas compressor separately of the motor drives of many platform independent, and air enters gas compressor by gas compressor air inlet A, B, and the high-pressure air that produces after the compression enters that the female pipe of backheat mixes and by the flue gas that discharges behind the turbine turbine; Air after the heating enters firing chamber and the fuel mix burning that is entered by firing chamber fuel inlet C, the high-temperature fuel gas that forms enters the acting of expanding in the turbine, the air horsepower of turbine output passes to load by coupling, and the waste heat flue gas that discharges behind the turbine enters the pressurized air behind the female pipe heating of the backheat gas compressor.Because gas compressor is driven by motor independently, but the rotating speed free adjustment of gas compressor.The load of combustion machine has determined the number of units of enabling of gas compressor.Improved the operational efficiency of gas compressor under the prerequisite that has satisfied the load wide variation, regenerator has further been saved fuel consumption simultaneously, so that Economy has also obtained certain raising on the basis of guaranteed performance.
