Since air dust such as mist, carbon fine particles in exhaust gas, and salt particles are suspended, such air dust causes corrosion and pollution inside the gas turbine, and particularly adheres to the air compressor c. Causing a decrease in performance of the air compressor c,
There is a problem of reducing the power generation output. Therefore, in order to prevent the intake of atmospheric dust, a dust collector (filter unit) e for mechanically separating and removing atmospheric dust from the air is provided at the air suction port d of the gas turbine a.
Is installed. As disclosed in Japanese Patent Application Laid-Open No. 5-106464, this filter unit e includes a coarse filter f made of a roll-type band-shaped glass fiber filter medium and a medium-performance filter g in which an ion exchange fiber filter is folded. Two
It is structured in stages. In the figure, h indicates a turbine portion of the gas turbine a, and i indicates a generator driven by the gas turbine a. The conventional gas turbine intake filter unit cannot sufficiently remove atmospheric dust, resulting in a reduction in power generation output of the gas turbine. Also, since the dust holding capacity is small, it is necessary to replace the filter 2-3 times a year. Becomes Therefore, it is desired to propose a long-life gas turbine intake filter unit that can replace the filter at the time of periodic inspection of the gas turbine, which is obligatory once a year with a highly efficient intake filter unit that does not reduce the power generation output.

という問題がある。SUMMARY OF THE INVENTION In order to meet the above-mentioned demands, the present inventors have a four-stage type of panel type demister, winding belt type or windsock type prefilter, box type medium performance filter, and box type high performance filter. However, there is a problem that the intake filter unit becomes large and the installation space and the equipment cost become large, and a countermeasure against it is desired. Therefore, from the viewpoint of low pressure loss, high efficiency, and long life, it was concluded that the medium performance filter and the high performance filter should be combined, and the prior art regarding the combination was referred, but each had a problem. First, for the purpose of reducing the installation space, in Japanese Utility Model Laid-Open No. 62-132715, a filter paper having a predetermined capacity is provided on the downstream side of the gas flowing in the casing, and a collection capacity on the upstream side thereof is lower than that of the filter paper. Although it is disclosed that filter paper is provided in multiple stages, there is a problem that the filter is not small and the purpose of reducing the installation space cannot be achieved. In addition, for the purpose of removing salt particles,
Japanese Patent No. 373 discloses that a space-holding body having a void is sandwiched between two filter media having water repellency. This is because even if salt particles become water droplets, they are along the back surface of the filter media on the upstream side. Therefore, there is a problem that the thickness of the filter medium becomes large, and the filter medium area cannot be made large because the filter medium has a life of 8000 hours or more, and the pressure loss also becomes large. In addition, filtration efficiency (0.1μ
For the purpose of obtaining a high efficiency of mDOP) of 99.99% or more (so-called ULPA), JP-A-54-94176 discloses that a filter medium is composed of two layers and particles are formed in a layer on the downstream side in the air flow direction. A filter medium having a filtration efficiency of 99.97% or more is arranged for particles having a diameter of 0.3 μm, and a particle size of 0.
It is disclosed that a filter medium having a filtration efficiency of less than 99.97% and 75% or more with respect to 3 μm particles is arranged, and these two layers of filter medium are folded in a zigzag shape in a state of being closely overlapped. Has two layers of filter media from the viewpoint of dimensional restrictions and ease of making, compared to the two-stage one, but the purpose is to achieve high efficiency and the life is not taken into consideration. In this case, there is a problem that the filter material is clogged quickly and the filter needs to be replaced 2-3 times a year or more.

The low-efficiency filter medium and the high-efficiency filter medium are closely stacked from the upstream side in the air flow direction, and the filter medium structure is characterized in that the filter medium area of each of these filter medium is 25 to 35 m 2 / unit. In addition, the particle size of the filter medium is 0.3 μm in the layer upstream of the air flow direction.
Dispose a filter medium having a filtration efficiency of 10 to 70% with respect to the particles of
90-9 for particles with a particle size of 0.3 μm in the downstream layer
It is preferable to dispose a filter medium having a filtration efficiency of 9.99%.
Further, the filter medium is folded in a zigzag shape so as to be uneven in the air flow direction, and a sheet is inserted into the folded gap portion to insert a separator into which the corrugation is corrugated, and the wave height of the refraction of the separator is set to the rear end in the insertion direction. It is preferable that the height on the side is made larger than the height on the tip side in the insertion direction to form a taper shape. Further, a gas turbine intake air intake filter unit of the present invention is a gas turbine intake air filter unit comprising a plurality of stages of dustproof filters, wherein the dustproof filter is a panel type demister from an upstream side in the air flow direction,
It is characterized in that it comprises three stages of a take-up belt type or a blow-off type pre-filter and the gas turbine intake high performance filter of the present invention. In addition, it is preferable that the pre-filter is a flow-through type and has a filter medium area of 2 to 8 m 2 / unit.

For example, animal and plant fibers and synthetic fibers. It is known that a large number of small elastic bodies are curled into a spring shape, and the small elastic bodies are coated and bonded with a binder to form a plate shape and enclosed in a metal frame. This demister generally has a thickness of 10 to 50 mm, a filtration efficiency (JIS type 8, colorimetric method) of 15 to 60% and a pressure loss of 1 to 10 mmAq at a wind speed of 2 m / s. The demister is characterized by a small pressure loss, that is, a small ventilation resistance and a high filtration efficiency against water drops, and when it becomes dirty, it can be reused by removing it from the frame and washing it. Of course, as the panel-type demister, a refraction-type blade-type eliminator in which rainwater is prevented from entering by a refraction path can also be used.

０ｇ／台である。As the prefilter constituting the gas turbine intake filter unit of the present invention, a take-up strip type or a windsock type is used. The take-up strip type is made of glass fiber as shown in FIG. A band-shaped filter medium 10 made of a filter-making medium is stretched so as to block the intake air passage 11, and a delivery roll 12 around which the filter medium 10 is wound is installed at the upper part and taken out from the delivery roll 12. A winding roll 13 for winding the filter medium 10 is installed in the lower part. This wound belt type pre-filter is generally a non-woven fabric using a filter medium material such as glass fiber and polyester fiber, a filter medium thickness of 20 to 70 mm, an average fiber diameter of 15 to 60 μm, and a wind speed of 2.5 m / s. Pressure loss is 4 to 8 mmAq, filtration efficiency (JIS15, weight method) is 60 to 90%, dust holding capacity is 500 to 1300.
It is g / m 2 . However, since the winding belt type requires maintenance of the drive unit for winding the filter medium, the following blower type having a wide filter medium area is preferable in order to be completely maintenance-free. As shown in FIG. 3 to FIG. 5, the windsock type has a head portion 24 having a plurality of bars 23 in which the filter medium 20 is formed by connecting a number of bags 21 to each other and the filter medium 20 is aligned with the opening 22. 2 screws to the frame body 25 via
It is attached with 6. However, the form is not limited to this, and may be a bag-like one that allows a desired filter medium area. In this flow-through type prefilter, generally, the filter medium has a thickness of 10 to 25 mm, the material is a dry nonwoven fabric of organic fibers such as polyester and acrylic, the average fiber diameter is 20 to 60 μm, the basis weight is 300 to 600 g / m 2 , and the wind speed is 2 The pressure loss at 0.5 m / s is 2 to 8 mmAq, the efficiency (JIS15 type, gravimetric method) is 60 to 90%, and using this filter medium, the filter medium area is 2 to 8 m 2 / unit, and the external dimension is vertical 5.
It was a flow-through type prefilter of 92 mm × width 592 mm × depth 500 mm. If the filter medium area is less than 2 m 2 / unit, the desired life of the filter unit cannot be obtained, and if the filter medium area exceeds 8 m 2 / unit, the pressure loss becomes high, which is not preferable. Therefore, the filter medium area is preferably 2 to 8 m 2 / unit. The performance of this filter is such that the pressure loss when the air volume is 50 m 3 / min is 2 to 8 mmAq, the efficiency (JIS15, weight method) is 60 to 90%, and the dust holding capacity is 1000 to 400.
It is 0 g / unit.

／台である。The high performance filter for gas turbine intake according to the present invention is obtained by combining a high efficiency filter medium and a low efficiency filter medium. The high efficiency filter medium has a particle size of 0.3 μm.
It is preferable to use a filter having a filtration efficiency of 90 to 99.99% with respect to the above particles. If it is less than 90%, it is not possible to prevent dust from adhering to the compressor of the gas turbine.
If it exceeds, it is effective for preventing dust from adhering, but the pressure loss increases, which causes a problem of shortening the life.
Further, as the low-efficiency filter medium, it is preferable to use one having a filtration efficiency of 10 to 70% with respect to particles having a particle size of 0.3 μm. This is because if it is less than 10%, the burden on the high-efficiency filter medium on the downstream side becomes large, and if it exceeds 70%, the problem that clogging of the filter medium becomes faster occurs. These high efficiency filter media 3
0a and the low-efficiency filter medium 30b are closely stacked,
In order to increase the area of the filter medium, it is folded in a zigzag shape so that it becomes uneven with respect to the flow direction of the intake air, and it is incorporated into a box-shaped frame body 31 with a sealing material 32, and a sheet is placed at the folding interval. Separator 3 bent into a wave shape
3 is inserted. Incidentally, as shown in the drawing, the separator 33
By using a so-called slanted separator in which the height H1 of the refraction of the above is larger than the height H1 on the rear end side in the insertion direction than the height on the front end side H2 in the insertion direction, the wave height of the refraction is increased like a normal separator. It is possible to improve the performance of the filter with a large amount of air as compared with a filter having a uniform length over the entire length. This high-performance filter generally has a thickness of each filter medium of 0.4 to 2.0 mm and a basis weight of 100 to 200 g /
Pressure loss at m 2 and wind speed of 5.3 cm / s is 5 to 45 m
mAq, efficiency (0.3 μm DOP) 90 to 99.9%
The separator is a metal foil of aluminum, stainless steel or the like, paper such as kraft or synthetic fiber, synthetic resin film such as polyarylate, polyethylene terephthalate, etc., the filter medium is zigzag, and the separator is inserted, and the filter medium area is 25 to 35m 2 / unit, external dimensions are vertical 610mm ×
A high-performance filter with a width of 610 mm and a depth of 290 mm was used. If the area of the filter medium is less than 25 m 2 / unit, the pressure loss becomes high and the life becomes short, and if it exceeds 35 m 2 / unit, there is a problem that the space between the filter medium cannot be maintained. Therefore, the filter medium area is preferably 25 to 35 m 2 / unit. The performance of this filter is such that the pressure loss when the air volume is 50 m 3 / min is 15 to 45 mmAq and the efficiency (0.3 μm DOP) is 90.

%, A filter medium with a large filter medium area of 25 to 30 m 2 / unit is used so that the pressure loss is not increased due to the dust passing through from the low efficiency filter medium on the upstream side to the high efficiency filter medium on the downstream side. For example, a high-efficiency filter medium capable of preventing the machine from being soiled and having a filtration efficiency of 90 to 99.99% for particles having a particle size of 0.3 μm is selected and arranged. By closely overlapping these low-efficiency filter media and high-efficiency filter media, it is possible to fold a large area of the filter media into the filter frame without increasing the thickness.

る。As is apparent from the above table, Japanese Patent Application Laid-Open No. 5-1
As described in JP-A-064644, in the two-stage type of the conventional winding band type pre-filter and box type medium performance filter, the output of the gas turbine is reduced by about 10% after long-term use. Further, the filter becomes clogged and the life of the filter is shortened, so that it is necessary to replace the filter and clean the compressor 2-3 times a year. Further, in Comparative Example 1, the efficiency of reducing the output of the gas turbine is as high as 99.97%, so the dust adhesion to the compressor can be prevented, the filter life can be extended, and the filter can be replaced once a year. However, the demister, pre-filter, medium-performance filter, and high-performance filter are four-stage type, and the installation space of the filter becomes huge and the equipment cost increases. On the other hand, in the first embodiment of the present invention, it is possible to combine the medium performance filter and the high performance filter, and
In the stepped type, the filter unit having a length of 3300 mm is 2300 mm in the present invention, and a space saving of about 1000 mm can be achieved, and the filtration efficiency is excellent as in Comparative Example 1, so that the dust adhesion to the compressor can be prevented, and more dust than that in Comparative Example 1. The holding capacity is increased due to the low pressure loss, and as a result, the life of the filter is further extended. However, since the pre-filter is of the winding band type and is automatic, maintenance and inspection of the drive unit are required due to the relation of the drive unit. Further, in the second embodiment of the present invention, by using the pre-filter of the first embodiment as a blow-off type, it is possible to prevent the output reduction of the gas turbine, save space, and achieve maintenance-free for 8,000 hours or more.

る。As described above, according to the gas turbine intake air filter unit of the present invention, it is sufficient to replace the filter only at the time of regular inspection once a year according to the law.
Maintenance work such as filter replacement and compressor cleaning is reduced. Further, since a high performance filter such as a HEPA filter is used, the output reduction of the gas turbine due to the adhesion of atmospheric dust can be suppressed. In addition, the intake filter unit is compact and space can be saved. Furthermore, since the number of filters is one and three steps less than that of the four-step type filter, the volume of waste such as used filters can be reduced. .
