PROBLEM TO BE SOLVED: To provide a filter device for gas turbine intake air capable of elongating a service life while suppressing pressure loss, and distributing a large amount of and high pressure air to a gas turbine generator while removing impurity particles and an impurity gas.SOLUTION: A filter device 2 for gas turbine intake air disposed on an intake portion of a gas turbine generator, includes a weather louver 3, a prefilter 4, a medium or high performance air filter 5, a chemical filter unit 6, and a quasi-HEPA filter or HEPA filter 7. The weather louver 3, the prefilter 4, the medium or high performance air filter 5, the chemical filter unit 6, and the quasi-HEPA filter or HEPA filter 7 are successively arranged in this order from an outer side of the intake portion in a direction toward the inside of the gas turbine generator. The chemical filter unit 6 is a unit in which a plurality of honeycomb filters 8 obtained by heating and molding an inorganic material including active carbon, are arranged on the same plane.SELECTED DRAWING: Figure 2 |
