Description of reference numerals: steam generator body 1, support 2, pillar 3, horizontal gird 4, diagonal brace 5, large plate-girder 6, girder 7, some secondary beams 8, upper area 9, lower area 10, buckstay 12, water-cooling wall top 13a, water-cooling wall bottom 13b, balance fixture 15
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation, but the present invention is not limited to following embodiment.
Fig. 1 illustrates a kind of steam generator, comprises the support 2 of steam generator body 1 and supporting body 1.Support 2 includes 4 vertically disposed pillars 3 and horizontal gird 4, and pillar 3 is fixed on basis.Pillar 3 interconnects with horizontal gird 4, and 4 horizontal girds 4 of same layer form a rectangle at horizontal level and pillar 3, and adjacent two pillars 3 form a rectangle with adjacent two horizontal girds 4 up and down.Because rectangle is unsettled, for center rest 2, according to leg-of-mutton stability principle, be provided with diagonal brace 5, one end of diagonal brace 5 is connected with the pillar of vertical direction 3, and the other end is connected with horizontal gird 4, makes like this four sides settle out.Support 2 arranges large plate-girder 6 above, and plate-girder 6 is comprised of some girders 7 and some secondary beams 8 greatly.Girder 7 is placed on support 2 and is attached thereto.Between girder 7, be parallel to each other, between secondary beam 8, be also parallel to each other, girder 7 is mutually vertical with secondary beam 8.
Upper area 9(at steam generator body 1 is generally vertical water wall region) in, in the space surrounding at water-cooling wall top 13a, interior arrangement being set, interior arrangement comprises economizer, superheater, reheater etc.The vertical column pipe that each interior arrangement is drawn by self is fixed on large plate-girder 6.13a outside in water-cooling wall top is surrounded by buckstay 12, buckstay 12 is waled water-cooling wall 13a and is born weight by water-cooling wall 13a, the buckstay 12 of two levels interconnects in water-cooling wall bight and is connected with water-cooling wall top 13a, and buckstay 12 consists of horizontal component and vertical component.Water-cooling wall consists of water-cooling wall top 13a and water-cooling wall bottom 13b.
Lower area 10(at steam generator body 1 is generally helical water-cooled wall region) in, being provided with spiral section water- cooling wall bottom 13b, 13a is identical with water-cooling wall top, and water-cooling wall bottom 13b mutually supports and is connected with buckstay 12.
Installation process:
Fig. 2 has shown scheme of installation of the present invention.
First step, mounting bracket 2, support 2 includes 4 vertically disposed pillars 3 and horizontal gird 4;
Second step, installs large plate-girder 6, when large plate-girder 6 is installed, directly secondary beam 8 is winched to girder 7 tops be connected with girder 7 from support 2 by crane; Due to the limited space in support 2, secondary beam 8 is larger, and original technology is in support 2, to be promoted to girder 7 tops, and the event that often can bump directly winches to secondary beam 8 girder 7 tops by crane therefore adopt from support 2.
Third step arranges interim hanging beam on horizontal gird 4;
The 4th step, on interim hanging beam, water-cooling wall top 13a is installed, when water-cooling wall top 13a is installed, each interior arrangement is assembled and fixed in relevant position inside the 13a of water-cooling wall top, mounted water-cooling wall top 13a is moved to large plate-girder 6 belows and suspension centre is installed complete; Water-cooling wall top 13a can be vertical water wall, can not be also vertical water wall;
After correct position below 13a quilt in water-cooling wall top winches to large plate-girder, water-cooling wall bottom 13b is also played to the below that winches to water-cooling wall bottom 13a, water-cooling wall top 13a and water-cooling wall bottom 13b and interior arrangement can be installed simultaneously.Interim hanging beam 14(here interim hanging beam can be same, also can be another root) the upper water-cooling wall bottom 13b that installs, when water-cooling wall 13b is installed, each interior arrangement relevant position inside water-cooling wall 13b is assembled and fixed, water-cooling wall top 13a is promoted to large plate-girder 6 belows and suspension centre is installed complete, remove interim hanging beam 14, and connect water-cooling wall top 13a and water-cooling wall bottom 13b; 13b can be helical water-cooled wall, can not be also helical water-cooled wall.
Because water-cooling wall is larger, water-cooling wall is generally divided into some screens, and water-cooling wall upper and lower all consists of some screens.Therefore above-mentioned installation method can use the screen to water-cooling wall, and the 4th step is:
Some screens of water-cooling wall are installed on interim hanging beam 14 simultaneously, when water wall panel is installed, each interior arrangement is assembled and fixed in the relevant position, inner side of water wall panel, subsequently the water wall panel or the mounted water wall panel of partial interior device that install interior arrangement are promoted to large plate-girder 6 belows and suspension centre are installed complete, dismounting is at interim hanging beam 14, and connects the some screens of water-cooling wall.
No matter the water-cooling wall upper and lower assembling is larger, if be fixed on the final position of large plate-girder below once, interior arrangement be installed and may be had installing space sufficient, and installation effectiveness is low.Therefore interim hanging beam is set on horizontal gird 4, water-cooling wall top or bottom are arranged on interim hanging beam, convenient, the position of interim hanging beam can be selected arbitrarily, and selected space is large.Installation effectiveness improves like this, the reduction of erection time.This patent by each interior arrangement as the heating surfaces such as economizer, superheater, reheater structure above water-cooling wall in complete installation separately.Mounting means reduction of erection time greatly by such time.
Fig. 3 is the guiding schematic diagram of a kind of steam generator balance fixture and support, because steam generator body 1 is to be suspended on large plate-girder 6, during operation, expansion downwards and left-right and front-back rock, need to body 1 is relatively fixing, making it not left-right and front-back rocks, for this reason, a plurality of balance fixtures 15 are set between the buckstay on body 1 12 and support 2.
This patent by each interior arrangement as the heating surfaces such as economizer, superheater, reheater structure above water-cooling wall in complete installation separately.Mounting means reduction of erection time greatly by such time.
Below only expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
