2. Description of the Related Art When a gas turbine burns, the inside of an air compressor is polluted with dust and the like in the sucked air, which lowers the output of the gas turbine. As a countermeasure against this, an intake filter for filtering the intake air with a filter. Has been installed. A pre-filter was used as this filter. However, in order to achieve efficient use of energy, improvement of gas turbine performance, and extension of the gas turbine overhaul and inspection cycle, the conventional intake filter with only a pre-filter is not sufficient for cleaning intake air. Therefore, the intake filter has been developed into a combination of a pre-filter and a medium-performance filter, and further into a combination of a pre-filter, a medium-performance filter and a high-performance filter, and the air cleaning process has been further advanced.

When the intake filter is composed of a combination of a pre-filter, a medium-performance filter and a high-performance filter, each of these filters is connected in series in the air flow direction as shown in FIG. However, there is a problem in that the total length of the intake air filter device becomes long because a space is required to replace each filter. Further, since the intake amount of the gas turbine is large, each filter is not used one by one, and two or more stages are stacked for each filter and two or more rows are arranged side by side, and a total of four or more are installed in the intake filter device. Often. Therefore, there is a problem that the intake filter device becomes large in width, height, and length and becomes heavy. In addition, the intake filter device is on the roof of the outdoor building,
Since it is often installed on a soundproof room of a gas turbine or on a pedestal installed on the ground, wind pressure resistance, snow resistance,
From the standpoint of earthquake resistance, it is desirable that the intake filter device be compact and lightweight. An object of the present invention is to provide a structure for reducing the size and weight of an intake air filter device.

As a measure for reducing the size and weight of an intake air filter device, it is conceivable to reduce the number of coarse dust particles, medium performance filters, and high performance filters. From the point of view, it is not desirable to reduce the number of these filters, ie the width and height dimensions of the intake filter device cannot be reduced. Therefore, we focused on shortening the length of the intake filter device. As a countermeasure, the weather louver for preventing rainwater intrusion attached to the front face of the intake air filter device is opened and closed, and the coarse dust filter is replaced from this front face. The intake filter device for a gas turbine of the present invention has a plurality of divided weather louvers attached to the front surface of the prefilter,
At least one of the divided weather louvers can be opened and closed like a door, the remaining weather louvers can be moved in the left-right direction, and the pre-filter can be replaced from the front opening thereof. It is preferable that one or both of the outermost portions of the divided weather louvers can be opened and closed like a door. It is preferable that all of the divided weather louvers can be opened and closed like a door. As the shape and structure of the weather louver in the present invention, conventionally known ones can be applied.

The weather louver has conventionally been fixed to the front surface of the intake filter device by bolts, but in the present invention, the width direction of the weather louver is divided into two or more, and at least one of them is connected to the front surface of the intake filter device. It can be opened and closed with a hinge. The remaining divided weather louvers can be moved left and right along guide grooves (or guide rails) provided on the upper and lower sides of the front surface of the intake air filter device. When inspecting or replacing the filter, open the weather louver that can be opened and closed, and inspect and replace the filter located in the opening. In this case, it is necessary to determine the size of the opening / closing weather louver so that the size of the opening is larger than the width of the filter. Next, with the weather louver open, the weather louver, which is movable left and right, is moved to the left or right to inspect and replace the filter located at the opening. This eliminates the need for a door for replacing the coarse dust filter, which was conventionally present on the side surface of the intake air filter device, and also eliminates the space for the replacement. This space is for an operator to enter inside and perform replacement work, and depending on the number of filter stages stacked in the height direction of the filter, it is roughly 6
A space having a width of about 00 to 800 mm is required. Therefore, the length of the intake filter device of the present invention is about 6
It can be shortened by 00 to 800 mm.

In the intake filter device for cleaning the combustion air of the gas turbine, the weather louver on the front surface of the intake filter device is divided into a plurality of parts, and the divided weather louvers can be freely opened and closed and can be moved left and right. By replacing the coarse dust filter through the openings with the structure, the space for replacing the coarse dust filter and the replacement door of the conventional structure have been eliminated, so the intake filter is significantly smaller and lighter. Thus, the manufacturing cost and weight of the intake air filter device itself can be reduced, so that the strength of the structure supporting the intake air filter device can be reduced and the economic effect can be great. In addition, when replacing the coarse dust filter that is the most likely to get dirty in the intake air filter, the dirty filter is replaced from the front side of the device, so that the inside of the intake air filter device is not contaminated.
