Description
Technical field
The invention belongs to the air inlet technical field of marine gas turbine, be specifically related to the voltage stabilizer of a kind of symmetric type filtering bending air inlet.
Background technique
Air inlet voltage stabilizer need be installed additional under normal circumstances in turbine suction port front end, air-flow in wherein inlet flow field is dredged and organized, prevent the air velocity distribution in inlet flow field from undergoing mutation, improve compressor efficiency and anti-asthma, thus make combustion engine can in work that can be stable under various operating mode.The air inlet plenum of traditional air inlet voltage stabilizer is excessive, and the useful space of boats and ships is declined, and this is disadvantageous to the intensity of boats and ships and the useful space, and plenum its efficiency excessive also can be had a greatly reduced quality.In addition, in order to adapt to gas turbine, air inlet voltage-stabilizing system all can be designed to bending-type, and air flows in air inlet plenum in the mode of side direction air inlet, then air-flow enters gas turbine through a series of turning back, this type of flow will inevitably to a certain degree cause velocity field on cross section, temperature field, pressure field equal distribution uneven, and the effect of transverse-pressure gradient and channel wall boundary layer also can produce vortex motion and secondary flow loss.Comparatively serious Secondary Flow and the break-off of boundary layer, great majority occur in diffuser, and this can make the velocity field of compressor inlet uneven, can make gas compressor generation surge, make whole gas turbine operation unstable.Therefore need to invent a kind of compact structure, play and reasonably organize air-flow, the voltage stabilizer of the effect of stable air is provided for downstream.
Summary of the invention
The object of the invention is the problem that the excessive and velocity field of air inlet plenum in order to solve traditional air inlet voltage stabilizer, temperature field, pressure field equal distribution are uneven, provide the voltage stabilizer of a kind of symmetric type filtering bending air inlet, its technological scheme is as follows:
The voltage stabilizer of a kind of symmetric type filtering bending air inlet, it comprises gas storage chamber, air-strainer, admission line, voltage stabilizing pipeline and compressor air inlet machine connection mouth, the suction port place of gas storage chamber is provided with air-strainer, gas storage chamber is connected with one end of admission line, the other end of suction tude is provided with voltage stabilizing pipeline, and the cross sectional area of voltage stabilizing pipeline is greater than the cross sectional area of admission line; Voltage stabilizing pipeline is connected with compressor air inlet machine connection mouth, and the cross sectional area of compressor air inlet machine connection mouth is less than the cross sectional area of voltage stabilizing pipeline; Described air-strainer is symmetrical warp architecture.
Beneficial effect of the present invention is: one, and air-strainer adopts the bending air inlet of symmetric type, changes the direction of charge air flow, air-flow can produce and cross after the filter of multiple directions in plenum, reduce the generation of flow instabilities, and increase air inlet area, increase air inflow; Two, add the voltage stabilizing pipeline that cross section is larger, the gas flow in admission line, in voltage stabilizing pipeline, reduces flow velocity, the temperature of gas, pressure, and flow velocity etc. re-start integration, and each parameter is compared more even.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
embodiment:
With reference to Fig. 1, the voltage stabilizer of a kind of symmetric type filtering bending air inlet, it comprises gas storage chamber 1, air-strainer 2, admission line 3, voltage stabilizing pipeline 4 and compressor air inlet machine connection mouth 5, the suction port place of gas storage chamber 1 is provided with air-strainer 2, gas storage chamber 1 is connected with one end of admission line 3, the other end of admission line 3 is provided with voltage stabilizing pipeline 4, and the cross sectional area of voltage stabilizing pipeline 4 is greater than the cross sectional area of admission line 3; Voltage stabilizing pipeline 4 is connected with compressor air inlet machine connection mouth 5, and the cross sectional area of compressor air inlet machine connection mouth 5 is less than the cross sectional area of voltage stabilizing pipeline 4; Described air-strainer 2 is symmetrical warp architecture.
Described air-strainer 2 is made up of three joints, and the two joint air-strainer 2 being positioned at both sides are 160 degree with a middle angle saving air-strainer 2.
Embodiment, the cross sectional area of gas storage chamber 1 is: long 5000mm × wide 6000mm; The cross sectional area of air inlet admission line 3 is: long 1500mm × wide 1500mm; The cross sectional area of voltage stabilizing pipeline 4 is: long 2000mm × wide by 2000.
Inventive principle: air enters into gas storage chamber 1 through the air-strainer 2 of the warp architecture of symmetry and produces and cross, and changes traditional vertical air inlet, carries out initial tissue and integration to air; The cross sectional area of voltage-stabiliser tube is larger than admission line 3 cross sectional area, and because this reducing flowing velocity, make air flow energy carry out secondary integration in voltage stabilizing pipeline 4, the parameter of All aspects of is even; Finally by admission line 3, the air-flow flowed out from voltage stabilizing pipeline 4 is accelerated, reach and enter pressure required in gas compressor and speed.
