Abstract

PURPOSE:To enable the operating floor of a turbine building to be used effectively by forming the turbine building which stores a turbine, turbine shielding plate and hygroscoptic moisture eliminators in such a way that the turbine shielding plates can be installed on the walls around the hygroscopic moisture eliminators. CONSTITUTION:In a turbine house 20, turbines 2 put in connection in series axially and generator 3 are arranged, and hygroscopic moisture eliminators 4 are arranged around the turbines 2. In addition an operating floor 5 is provided on the installation floor of the turbines 2. In this case, shielding wall 21 formed with concrete wall is arranged around the hygroscopic moisture eliminators 4 due to the requirement or the like stemming from radiation shield, and embedded hardwares 22 in which lugs 23 are planted are added to the upper and lower positions of this shielding wall 21. Also cutout portions 25 are formed at plural places on the circumference of turbine shielding plates 24 surrounding the turbines 2 so that the shielding plates 24 which are lifted by a crane or the like at the time of decomposition checking for equipment can be installed on the shielding wall 21 by means of linking the cutout portions 25 on the lugs 23.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a turbine building that houses a turbine.

(Prior Art) A conventional turbine building will be explained with reference to FIG. Fourth
In the figure, a turbine 2 is disposed within the turbine building Plil, and a generator 3 is disposed on an axial extension of the turbine 2. Moisture separation around this turbine 2! A4 is a layout line, and an operating floor 5 is formed in the installation area of the turbine 2. The operating floor 5 is provided with a hatch 6 used for various errands and a decontamination area 7 for decontaminating used parts and the like.

In the turbine building Ml configured as described above, the turbine 2 and the generator 3 are periodically overhauled and inspected to maintain their performance and function. During such overhaul work, the turbine rotor 8 forming the turbine 2 is within the movable range of a crane (not shown) installed in the turbine building 1, as shown by the two-dot chain line A in FIG. and turbine casing9. Many parts such as the turbine diaphragm 10, generator rotor 11, and turbine shield plate 12 are laid down.

(Problem to be solved by the invention) In the above configuration, the laydown area is within the movable range of the crane and avoids decontamination sites, etc., so the range of this laydown area is extremely limited. . Additionally, laydown space is further reduced in power plants where moisture separators are located within the operating floor.

Under these circumstances, laying down many parts of turbines and generators will reduce the efficiency of work such as disassembly and inspection, and if there is insufficient laydown space, temporary storage may be prepared in a completely different location. This caused problems such as having to do so.

The purpose of the present invention is to expand the range of laydown by minimizing the number of parts such as turbines to be laid down on the operating floor in the turbine building,
Furthermore, the objective is to obtain a turbine building that can improve the efficiency of overhaul work.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a turbine, a turbine baffle plate disposed around the turbine, and a moisture barrier disposed on the side of the turbine. The present invention provides a turbine building housing a separator, wherein the turbine baffle plate is configured to be attachable to a wall surrounding the moisture separator.

(effect) In a turbine building configured in this way.

Since the turbine shield plate can be attached to the wall surrounding the moisture separator during overhaul of the turbine, the operating floor of the turbine building can be utilized more effectively.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 3. Here, FIG. 1 and FIG. 2 show a partially cutaway plan view and an enlarged vertical cross-sectional view of a main part of a turbine building according to an embodiment of the present invention. In FIGS. 1 and 2, the same parts as in FIG. 4 are designated by the same reference numerals, and the explanation of the structure of the parts will be omitted. In the turbine building 20 where the moisture separator 4 is placed on the operating floor 5, the moisture separator 4 is surrounded by a concrete wall with a thickness of about 1 m due to the requirement of radiation resistance. Hey! 21 are arranged. This moisture separator
As shown in FIG. 3, an embedded metal fitting 22 is installed in i21, and a lug 23 is formed on this embedded metal fitting 22.

On the other hand, for plate-shaped items such as the turbine baffle plate 24 that surrounds the turbine 2 for protection against radiation from the turbine 2 during normal operation, notches 25 are formed at multiple locations around the plate. ing.

In the moisture separator baffle wall 21 and turbine plate 24 configured as described above, when laying down the turbine 2 and generator 3 during overhaul, the turbine baffle plate 21
is lifted by the turbine building crane 26 disposed above the turbine 2, and the moisture separator and barrier wall 2
It is sealed by a lug 23 provided at 1.

The above is an embodiment of the present invention, and the moisture separator and barrier wall 24 within the range of movement of the crane is approximately 500 mm.
Not only the turbine baffle plate 24, but also those that have a plate-like appearance, or those that can be disassembled into plate shapes, can be laid down by wall-mounting.

Since the turbine building according to the present invention is constructed as described above, there is no need to secure a lay-down space for turbine shingles or the like on the operating floor, thereby improving the efficiency of overhaul work on the operating floor. be able to. Furthermore, by reducing the laydown space, the turbine building can be reduced, resulting in a more compact building.

〔Effect of the invention〕

According to the turbine building according to the present invention, plate-shaped parts such as turbine shingles can be attached to the wall, so the equipment required for overhauling these parts can be reduced, and the range of use of the operating floor can be expanded. The efficiency of overhaul work can be improved.
