Abstract
The utility model discloses a vane adjustable component seal protection structure for blast furnace gas turbine plant including a shell of the blast furnace gas turbine plant, a vane adjustable component as well as its adjustable vane. The plant is characterized in that the cylinder of the vane adjustable component is a monolithic construction. The cavity is filled with nitrogen with circumferential stamping steel ribbon arranged at two ends. The splits between the vane and the cylinder and between the shell and the cylinder are provided with a notch groove in which a stamping steel ribbon is added. As the cylinder of the monolithic construction is filled with nitrogen and a certain pressure is assured in the cylinder, the blast furnace gas can be effectively prevented from leaking to enter the cavity, which makes the vane adjustable component under a protection state so as not to be polluted by gas.
Description
Technical field
The utility model relates to a kind of parts of blast furnace gas energy recovery turbine set, particularly a kind of stator blade adjusting part protection sealing configuration of blast furnace gas turbine installation.
Background technique
Blast furnace gas energy recovery turbine set is that the gas pressure in the blast furnace can be transformed into great environmental protection, the energy saving device that drives the generator set generating.It has the effect of two aspects: the pressure energy and the heat energy that 1) reclaim blast furnace gas; 2) stablize blast furnace top pressure, improve furnace processor.The stator blade controlling device is arranged in this device,, regulate the pressure of stablizing coal gas, and make the blast furnace gas turbine at the operation of efficient district, many recovered energies in order to change the stator blade angle.The medium of this device is a blast furnace gas, still contains impurity such as a large amount of dusts, water and tar through after the dedusting.Because the stator blade controlling device is in blast furnace gas energy recovery turbine set inside, the place cavity is because the leakage of coal gas is polluted, and oil, water, dust mix and be attached on regulator site, make adjusting dumb, and precision is not enough, to such an extent as to or be subjected to stuck damage.
Summary of the invention
Contaminated in order to overcome in the above-mentioned blast furnace gas energy recovery turbine set controlling mechanism; regulate inflexible shortcoming; the objective of the invention is to; a kind of seal protection structure of stator blade adjusting part of blast furnace gas turbine installation is provided; sealing protection structure can be protected the adjusting parts of blast furnace gas energy recovery turbine set; prevent because blast furnace gas turbine installation gas leakage is polluted; and do not have oil, water, dust at regulator site and mix and stick, guarantee the normal reliability of operation of stator blade adjusting part.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of stator blade adjusting part seal protection structure of blast furnace gas turbine installation; the frame, stator blade adjusting part and the variable stator vane angle thereof that comprise the blast furnace gas turbine installation; it is characterized in that; the cylinder that holds of described stator blade adjusting part is an overall structure; be filled with nitrogen in the cavity; two ends dispose the circumferential seal bar, and are provided with cutting at stator blade and the split that holds the split and the frame of cylinder and hold cylinder, are added with Stamping Steel Ribbon in the cutting.
The stator blade adjusting part seal protection structure of blast furnace gas turbine installation of the present utility model; since integrally-built hold to fill with nitrogen in the cylinder and guarantee certain pressure is arranged; can prevent effectively that the blast furnace gas leakage from entering this cavity; make the stator blade adjusting part be in guard mode, prevented that effectively the stator blade adjusting part is subjected to the pollution of coal gas.

Fig. 1 is blast furnace gas energy recovery turbine set figure;
Fig. 2 is a stator blade adjusting part protective position enlarged view;
Label among the figure is represented: 1, frame (casing), 2, the stator blade adjusting part, 3, cavity, 4, the inflated with nitrogen mouth, 5, center line.21, shell mid-separate surface seal bar, 22, the circumferential seal bar, 23, blade holds cylinder mid-separate surface seal bar, 24, variable stator vane angle, 25, whole stator blade holds cylinder.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
The stator blade adjusting part plays an important role in blast furnace gas energy recovery turbine set figure, regulates the variable working condition of turbine, stablizes furnace top pressure, improves furnace processor, improves the turbine reuse efficiency.
Fig. 1 is blast furnace gas energy recovery turbine set figure.Center line 5 is the signal of blast furnace gas turbine installation split with top among the figure, and center line 5 has shown the vertical split surface of blast furnace gas turbine installation with the bottom.The utility model is that the cylinder that holds at the stator blade adjusting part 2 of existing blast furnace gas turbine installation carries out architecture advances; provide a kind of seal protection structure of stator blade adjusting part; it comprises the variable stator vane angle that connects on frame 1, stator blade adjusting part 2 and the adjusting part 2 thereof; the cylinder that holds of stator blade adjusting part 2 changes overall structure into by original branch body structure; and in cavity 3, be filled with nitrogen; inflated with nitrogen mouth 4 is arranged on an end of variable stator vane angle 24, so that cavity is charged into nitrogen.
Fig. 2 is a stator blade adjusting part protective position enlarged view; mainly provided sealing means of the present utility model among the figure; whole stator blade holds cylinder 25 two ends and disposes circumferential seal bar 22; and be provided with cutting at variable stator vane angle 24 and the split that holds the split and the frame of cylinder and hold cylinder, be added with shell mid-separate surface seal bar 21 and blade in the cutting and hold cylinder mid-separate surface seal bar 23.This protection structure makes the nitrogen that fills in the Seal cage not leak outside, and rough gas also can't enter in the chamber, has protected controlling mechanism not contaminated.
