Description
Technical field
The present invention relates to gas turbine, and in particular to one kind prevents gas turbine inlet air system willow catkins flying in the air from blocking gas handling system filter
The anti-willow catkins flying in the air device of gas turbine inlet air system of core.
Background technology
At present, protection of the gas turbine inlet air system generally for willow catkins flying in the air is weaker.Partial-air admission system is not provided with anti-willow catkins flying in the air
Device, in atmosphere in the presence of a large amount of willow catkins flying in the air in the case of, willow catkins flying in the air largely attach to gas handling system cartridge surface, humidity environment
Lower generation is permanent hardened.On the one hand cause the too frequent of filter core to be changed, cause largely to waste.On the other hand filtering system is caused
System pressure difference raises rapidly, causes unit non-programmed halt or drop to contribute and run, has certain potential safety hazard.Part is provided with anti-
The gas handling system of willow catkins flying in the air net, the overstocked then easy blocking of mesh, the excessively thin then interception willow catkins flying in the air effect of mesh is poor, and both can not take into account.

With reference to figure 6 to Fig. 8, as shown in Figure 6 to 8, in steel wire recovery bin 4, steel wire recovery bin housing 41 is main
Function as follows：
Clean steel wire after blowback is played a protective role；
The willow catkins flying in the air to blow off are played with certain receiving effect, and its favorable current is transported in willow catkins flying in the air suction channel 51；
Steel wire recovery bin roller 42 and roller scrolling mechanism 43 are played a supporting role；It is with steel wire 2 and enters air frame
The annexation of frame 3 is shown in partial view；
With reference to figure 9, as shown in figure 9, in willow catkins flying in the air collection device 5, pumping blower fan 54 is used for willow catkins flying in the air collection device case
52 are exhausted, and make it have certain vacuum degree；By the willow catkins flying in the air that back-blowing device 44 blows off by entering after willow catkins flying in the air suction channel 51
Cloth-bag type filter screen 53；Wherein, cloth-bag type filter screen 53 belongs to the part that can be changed.
The effect of the anti-willow catkins flying in the air device feature of gas turbine inlet air system：
Steel wire 2：Steel wire is the main part for intercepting willow catkins flying in the air；The mesh number of steel wire is according to contained by different geographical air
Willow catkins flying in the air composition is varied from, and generally thick and heavy catkin uses less mesh mesh number, and vice versa；
Air inlet framework 3：Air inlet chassis body forms for steel construction, and its shape has according to the filter of downstream different size
Changed；The function of main body frame is connection gas handling system, and the anti-other parts of willow catkins flying in the air device of gas handling system install admittedly
It is fixed；Its working condition is：Strip silk screen one side is air-flow upstream, and downstream part is connected with gas turbine inlet air system sealing；
Willow catkins flying in the air collection device 5：The willow catkins flying in the air of steel wire are peeled off after blowback can not enter air so as to be carried out again to filter screen
Pollution, it is therefore desirable to which willow catkins flying in the air are collected；Blower fan in willow catkins flying in the air collection device aspirates to the willow catkins flying in the air to blow off, and favorable current
Caught by cloth envelop collector；
Steel wire storehouse 1 and steel wire recovery bin 4：Two mechanism primarily serves the effect of storage steel wire, while to cleaning
Steel wire play a protective role；Meanwhile two warehouses carry reel wire mechanism, mechanism effect is enough in wire rope net surface accumulation
Willow catkins flying in the air, when steel wire upstream and downstream pressure difference is excessive, scrolling steel wire, the steel wire for making not yet to be infected with willow catkins flying in the air enters air inlet framework
Porch, while the steel wire for having caught willow catkins flying in the air enters back-blowing device progress blowback and removes catkin；
Back-blowing device 44：Back-blowing device is carried out using 2bar compressed air as source of the gas to the willow catkins flying in the air being attached on steel wire
Purging；Because willow catkins flying in the air generally exist in dry weather, therefore compressed air can reach good effect of blowing off to willow catkins flying in the air.
In the anti-willow catkins flying in the air device of the gas turbine inlet air system, air intake steel wire, which is constantly caught in surrounding air, to fly
Wadding, while gas turbine can monitor gas handling system pitot loss in itself；When pitot loss reaches certain numerical value, anti-willow catkins flying in the air system
System passes through scrolling steel wire, the clean steel wire in steel wire storehouse is devoted oneself to work, so as to reduce gas handling system total pressure head；
After steel wire in steel wire storehouse finishes close to use, by reverse scrolling steel wire, the recycling of next round is carried out；
When during clean steel wire constantly puts into operation, contaminated steel wire enters steel wire recovery bin；In recovery bin
Inside, row's shower nozzle carry out blowback to steel wire；In steel wire constantly after blowback recovers clean state again, final winding with
On recovery bin roller；
During blowback is carried out to steel wire, willow catkins flying in the air retracting device is constantly aspirated to recovery bin, and willow catkins flying in the air are sucked
In the sack cleaner of retracting device；Because sack cleaner is easy to clean, so as to reach the recycling of whole system；
Preferably, a large amount of steel wires are wound by roller in steel wire storehouse, intercepted greatly in the steel wire to put into operation
After measuring willow catkins flying in the air, the clean steel wire in steel wire storehouse can substitute contaminated steel wire and be operated, so as to reduce combustion gas wheel
Machine gas handling system total pressure head；
Preferably, the winding of steel wire is replaced work and carried out automatically by system, when monitoring that filtration system total pressure head reaches
After certain numerical value, motor automatic coiling roller carries out the replacement of new and old steel wire；
Preferably, contaminated steel wire is purged, by interception before steel wire recovery bin is entered by blowback system
Willow catkins flying in the air blow off；
Preferably, after the willow catkins flying in the air being intercepted on steel wire are blown off, aspirated by willow catkins flying in the air collection device；Willow catkins flying in the air pass through pipe
Road enters the sack cleaner of willow catkins flying in the air collection device, it is therefore prevented that secondary pollution of the willow catkins flying in the air to air.
The present invention protects because gas turbine inlet air filtration system main function is that molecule is filtered out so as to play
Protect the effect of gas turbine passage component.
Usual inlet air filter system will be changed after pressure difference reaches certain numerical value to filter cylinder.In atmosphere containing big
In the case of measuring willow catkins flying in the air, filtration system filter core is due to that can adhere to a large amount of willow catkins flying in the air in a short time, so as to greatly reduce filter core
Service life, cause economic loss.
The present invention avoids well in willow catkins flying in the air season：In the case of filtration system pressure difference rapid growth, easily cause combustion
Gas-turbine generating set influences heat and power supply, and then influence profit from power plant by forced-stopping machine；Such accident is set no longer to occur.This hair
It is bright that willow catkins flying in the air are intercepted using steel wire, and after certain interception amount is reached, blowback, collection are carried out to the willow catkins flying in the air on its surface,
So as to reach the uninterrupted purpose persistently used.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
