Abstract
The utility model relates to a stator blade adjustable device to control furnace top pressure, which comprises a housing 5 that is characterized in that the housing 5 is composed of a stator blade carrier cylinder 1; the stator blade carrier cylinder 1 is arranged with a stator blade bearing 2; the stator blade bearing 2 is provided with a stator blade 6 in the lower part; the utility model has advantages of low pressure loss, high adjustment efficiency, high adjustment quality and low cost.
Description
Technical field
The utility model relates to a kind of stator blade tunable arrangement of controlling furnace top pressure.
Background technology
In the background technology, in traditional blast-furnace top gas recovery recovery gas turbine unit (being called for short TRT), be to regulate and control stove item pressure with speed-regulating valve, owing to the structural reason of speed-regulating valve itself, the pressure-losses is big, and adjusting efficient is low, regulate the blast furnace top pressure poor quality, the manufacturing cost height.
The utility model content
The utility model has solved and has utilized speed-regulating valve to regulate big, the adjusting technical problem that efficient is low, regulation quality is low of turbine unit crushing of furnace top pressure in the background technology.
The technical solution of the utility model is: the utility model comprises casing 5, and its special character is: be provided with stator blade in the described casing 5 and hold cylinder 1, this stator blade holds cylinder 1 and is provided with stator blade bearing 2, and stator blade bearing 2 belows are provided with stator blade 6.
Above-mentioned stator blade 6 is the one-level stator blade, and stator blade bearing 2 tops are provided with guide collar 4, and guide collar 4 connects with stator blade 6 by slider-crank mechanism 3.
Above-mentioned stator blade 6 comprises first step stator blade 10 and second stage stator blade 9, and stator blade bearing 2 tops are provided with regulates cylinder 8, regulates cylinder 8 and connects with stator blade 6 by slider-crank mechanism 3.
Above-mentioned adjusting cylinder 8 is arranged on the casing 5 by regulating cylinder supporting 7.
The utility model utilizes the stator blade tunable arrangement to replace speed-regulating valve to regulate the control furnace top pressure, by adjusting to the stator blade different rotation angle, stator blade is adjustable finishes the conversion of operating mode, and does not have the throttling loss of pressure energy, and its no crushing, adjusting efficient height, regulation quality height and cost are low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two;
Fig. 3 is the workflow diagram of the utility model in blast furnace system.
Embodiment
Referring to Fig. 1, the utility model comprises casing 5, is provided with stator blade in the casing 5 and holds cylinder 1, and stator blade holds cylinder 1 and is provided with stator blade bearing 2, and described stator blade bearing 2 belows are provided with stator blade 6; As blast furnace volume≤1650m
3The time, adopt the one-level stator blade adjustable, stator blade bearing 2 tops are provided with guide collar 4, and described guide collar 4 connects with stator blade 6 by slider-crank mechanism 3, the rotation of guide collar 4 can be converted into the rotation of stator blade 6 by slider-crank mechanism 3; Guide collar 4 connects with servomotor.During work, drive guide collar 4 by servomotor and rotate, guide collar 4 by slider-crank mechanism 3, rotates stator blade 6 again, makes opening greatly or turning down of stator blade installation angle, changes the size that flows through the turbine flow, reaches the effect of regulating operating mode and controlling furnace top pressure
Referring to Fig. 2, as blast furnace volume 〉=1650m
3The time, adopt the two-stage stator blade adjustable, stator blade 6 comprises first step stator blade 10 and second stage stator blade 9, Dui Ying stator blade bearing 2 and slider-crank mechanism 3 also are two groups with it, stator blade bearing 2 tops are provided with regulates cylinder 8, regulate cylinder 8 and be arranged on the casing 5 by regulating cylinder supporting 7, it connects with stator blade 6 by slider-crank mechanism 3, the translation of regulating cylinder 8 can be converted into the rotation of stator blade 6 by slider-crank mechanism 3; Regulating cylinder 8 connects with servomotor 11.During work, drive adjusting cylinder 8 synchronously by two servomotors 11 and do axial motion, for closing, turn down static blade angle left; Big for opening to the right, open big static blade angle, make the change of two-stage stator blade installation angle big or diminish, change the size that flows through the turbine flow, reach the effect of regulating operating mode and controlling furnace top pressure.
Referring to Fig. 3, in the blast furnace ironmaking process, the blast furnace gas that produces through hotblast stove, blast furnace, particle collector and wet scrubber is by the stator blade tunable arrangement in the TRT device, the pressure energy that utilizes blast furnace gas to produce, by TRT expansion acting, drive generator, mechanical energy is converted into electric energy.
