Description
Technical field
The utility model is related to gas turbine technology fields, specially gas turbine inlet air filtration system.
Background technology
Gas turbine is using the gas continuously flowed as working medium impeller high speed rotation, by the energy conversion of fuel to have
Diligent internal combustion type dynamic power machine is a kind of rotary vane type Thermal Motor.The course of work of gas turbine is compressor
(i.e. compressor) continuously sucks air and is compressed it from air；Compressed air enters combustion chamber, the combustion with penetrating
Material mixing after-combustion, becomes high-temperature fuel gas, flows into expansion working in gas turbine immediately, pushes turbine wheel with gas compressor blade
Wheel rotates together；The capacity for work of high-temperature fuel gas after heating significantly improves, thus gas turbine is while compressor is driven,
Still there is output mechanical work of the complementary work as gas turbine.When gas turbine is by standing start, starter need to be used with rotation, it is to be added
After speed to energy independent operating, starter just disengages.The course of work of gas turbine is simplest, referred to as simple cycle；In addition,
Also extraction cycle and complex loops.The working medium of gas turbine comes from air, last to drain into air again, is open circulation；In addition,
Also working medium is closed the closed cycle of recycling.Gas turbine is known as combined cycle plant with what other heat engines were combined.
Gas turbine is made of compressor, combustion chamber and gas turbine etc..Compressor has axial-flow type and two kinds centrifugal, and axial-flow type is calmed the anger
Engine efficiency is higher, suitable for the occasion of big flow.In small flow, axial-flow compressor is because several grade blades below are very short, efficiency
Less than centrifugal.Power is in several megawatts of gas turbine, some compressors using axial-flow type add one it is centrifugal make final stage, because
And shorten axial length while greater efficiency is reached.The future developing trend of gas turbine is to improve efficiency, use
High-temperature ceramic materials utilize nuclear energy and development coal combustion technology.It is to improve combustion gas initial temperature to put forward efficient key, that is, improves turbine leaf
The cooling technology of piece develops the high-temperature material for being resistant to higher temperature.Secondly improving compression ratio, series less compression ratio is developed
Higher compressor.It is the efficiency for improving all parts again.
From 168 test run combustion engine oepration at full load November in 2016, exist to combustion engine gas handling system strainer pressure difference on December 08
Alarming value is comparatively fast risen in such short time.Check that the inside for finding gas handling system coarse filtration is adsorbed with a large amount of dust after shutdown
And being formed on surface hardened, coarse filtration differential pressure has reached stale value；Refined filtration surface blackening is serious, and refined filtration pressure difference rises very fast.It is comprehensive
The reason of analyzing pressure difference formation, it is believed that there are the following problems for Site Design：
1st, since air problem in recent years is increasingly severe, haze weather increases, and dustiness is high, and how overcast and rainy the south of the lower reaches of the Yangtze River is
Weather, dust, humidity in air increase, and the plate and frame coarse filtration dust containing capacity of original design G4 precision is limited, and combustion engine is caused to be transported
Air inlet rough filtering failure is very fast during row, shortens refined filtration service life.
2nd, air inlet rough filtering, refined filtration are arranged in pulse filter module, if replacing coarse filtration, filtered dirty sky during operation
Gas can cause refined filtration a degree of damage, and due to the presence of intake pressure difference, the replacement of coarse filtration should not be carried out, during operation
When appearance coarse filtration pressure difference is excessive, then shutdown is needed to be handled.As thermal power plant unit, very big economic damage can be caused by forced-stopping machine
It loses.
3rd, meet an urgent need boiler, induced cooling tower be arranged in the northeast corner in combustion engine room with it is positive in the east, and with combustion engine room
It is closer to the distance, when east wind a large amount of steam discharge of boiler, induced cooling tower of meeting an urgent need enter the inlet scoop of combustion engine gas handling system, greatly
The air of humidity is greatly to test to combustion engine air inlet screen.
4th, the floss hole design of combustion engine lubricating oil oil-smoke expulsion pipe, fuel engine power generation secret oil sealing smoke discharging pipe stretching workshop exists
Combustion engine gas handling system air inlet elbow depends on Xi Chu, and lasting oil smoke easily accumulates in fuel engine power generation computer room top, due to combustion engine air inlet air draught
The tiny structure of mouth, oil smoke are inhaled into gas handling system pollution strainer, and oily matter is adhered on refined filtration papery filter cylinder and easily causes to block up
Plug, and be difficult to be cleared up with compressed air blowback.
In conclusion the filter effect of traditional gas turbine inlet air filtration system is difficult to ensure that, to gas turbine inlet air
The improvement of filtration system is extremely urgent.
