Description

TECHNICAL FIELD [0001] The present invention relates to a turbine having a rotatable inner casing and a turbine comprising a rotatable inner casing,

The present invention relates to a blast furnace constant-pressure generator turbine including a rotatable inner casing, and more particularly, to a turbine including a rotatable inner casing, which prevents accumulation and accumulation of dust in the turbine, To a turbine of a furnace < RTI ID = 0.0 > stationary < / RTI > generator including a rotatable inner casing.

It is a system that generates electricity using waste energy, which is a high-pressure gas generated at the furnace top of a furnace in a steel mill. To improve the productivity of a furnace for making pig iron (iron), and to reduce fuel costs, . This energy is used for the dust removal of the gas until now, and most of it is released simply. It is recovered and it is possible to generate electricity by rotating the turbine by the inflation force when returning to atmospheric pressure from about 3 atm. In order to utilize the waste energy by the non-static power generation, it is possible to save the energy and reduce the cost. For this purpose, the blast furnace facility for high pressure operation generally uses the high temperature and high pressure blast furnace gas discharged from the blast furnace There is a furnace generator with a turbine to convert the energy of the blast furnace gas into electric power.

The blast furnace gas (BFG) is an exhaust gas generated from the blast furnace of a steel mill. Its composition is similar to that of coke oven gas. Since coke is incompletely combusted, it contains carbon monoxide, nitrogen and carbon dioxide , And also contains a large amount of dust. The amount of heat generated is very low, but it is recovered and used as a heat source in the factory. It is usually used as fuel for heating a coke furnace attached to a furnace.

In order to generate such a constant pressure power, a high-temperature and high-pressure blast furnace gas containing a large amount of dust, including dust, discharged from the upper part of the furnace (hearth) is primary-damped in a dry dust collector and then subjected to secondary damping in a wet dust collector. Next, the secondary-damped gas is controlled by the pressure control means connected to the furnace pressure controller, and then the generator turbine is rotated to generate electric power, which is subsequently stored in the gas holder and reused as fuel.

On the other hand, in the turbine used for the furnace pressure generation, a plurality of fixed wings are mounted on an inner casing through which blast furnace gas passes, a plurality of rotor blades are mounted on a rotary shaft rotatably fixed in the inner casing, The inner rotor rotates the rotary shaft through which the rotor blades and the rotor blades are fixed by applying pressure to the rotor blades while passing through the inner casing, and transmits the rotational force of the rotary shaft to the generator to generate power. At this time, the fixed wing is fixed to the inner casing in such a manner that its mounting angle is variable, and the direction of the blast furnace gas is controlled according to the pressure of the blast furnace gas by varying the mounting angle of the fixed wick, .

However, even if the dust is removed double through the dry dust collectors and the wet dust collectors, the dust is still contained in the turbine parts used for the static electricity generation for a long time, Resulting in deterioration of power generation. In addition, in order to remove such dust, the operation of the turbine is interrupted for a certain period of time and the decomposition agent is mainly performed. In addition to the waste of time and manpower, the power generation is stopped and the normal operation of the blast furnace is also affected. The result is the result. Particularly, due to the effect of gravity, dust is more deposited on the fixed blade located in the lower part of the fixed blade of the turbine. Therefore, the deposited dust is more difficult to remove and the amount of dust deposited over time is increased.

As shown in Figs. 3 and 4, a turbine of a blast furnace constant-voltage generator including a rotatable inner casing according to the present invention has a first gear groove 12 formed on an outer surface thereof, An inner casing (11) rotatable by a first rotary machine part (13) that is gear-coupled to the inner casing (11); And a second rotary gear 15 fixed to the outer surface of the inner casing 11 so as to be slidable and having a second gear groove 141 formed on the outer surface thereof and gear- A slide rotation body (14) rotatably fixed; And a second gear portion (161) that is gear-engaged with a first gear portion (142) formed on one side of the slide rotation body (14) (16); At least one fixed wing (17) hingedly fixed to the inner surface of the inner casing (11) and variable by the fixed wing changing means (16); And a rotary shaft (S) rotatably fixed to the inner casing (11) and including at least one or more rotor blades. The rotary shaft (S) according to the present invention having the above- The corona-stabilized generator turbine including the casing includes a rotatable inner casing 11 to prevent accumulation and accumulation of dust in the turbine, particularly to prevent the accumulation and accumulation of dust in the turbine, It is possible to secure the flow path by preventing the dust from being deposited more and to maintain the high power generation efficiency.

1 is a perspective view of a blast furnace constant pressure power generation system according to a first embodiment of the present invention; FIG. 2 is a cross- The high-temperature and high-pressure gas discharged from the furnace (furnace) contains a large amount of dust and is firstly subjected to primary dust removal in the dry dust collector 2 and then secondary dusted in the wet dust collector 3. Next, the secondary pressurized gas is controlled by the boshis cone (4) connected to the furnace pressure controller and the pressure of the front stage pressure signal transmitter is controlled by the front stage pressure controller of the furnace pressure generator (5) After controlling the shear pressure through the bypass control valve and the turbine control valve, the generator turbine is rotated to generate electric power, which is stored in the gas holder and reused as fuel.

The inner casing 11 has a plurality of fixed wings fixed to the inner surface thereof, and the fixed wing has a function of concentrating the blast furnace gas toward at least one or more rotating wicks which are fixed to the rotating shaft and are rotatable, And rotates the generator turbine connected to the rotation shaft to generate electric power. Unlike the rotatable inner casing 11 of the present invention, a non-rotatable inner casing 6 is used, and a plurality of fixed wings 7 are provided on the inner surface of the inner casing 6, And a plurality of rotor blades 8 fixed to the rotary shaft S and a toilet bowl 9 for fixing the rotor blade 7 is fixed to the outer surface of the inner casing 6, , The conventional inner casing 6 has been fixed so as not to be able to rotate. Particularly, in the conventional non-rotatable inner casing, particulate is more deposited on the fixed blade located below the fixed blade of the turbine due to the effect of gravity, and the deposited dust is more difficult to remove and the amount of dust deposited over time is increased there was. Therefore, in the present invention, since the inner casing including the fixed-end variable means is rotatably provided, including the fixed-point variable means for varying the fixed-wing, the dust is more likely to flow to the fixed- It is characterized in that it is prevented from being deposited much, and deposition of dust over time is prevented, thereby securing a flow path and maintaining a high power generation efficiency.

3 and 4, a rotation shaft S is rotatably fixed to the inner casing 11, and at least one rotor blade is fixed to the rotation shaft S.

A first gear groove 12 is formed on the outer surface of the inner casing 11 for rotation of the inner casing 11 and the first rotary gear 13 is engaged with the first gear groove 12, And the first rotary machine 13 is rotationally driven by the first driving means M1 such as an electric motor. Therefore, when the first rotary member 13 is rotated by the rotation of the first drive means M1 and the first rotary member 13 is rotated by the rotation of the first rotary member 13, So that the inner casing 11 itself can be rotated.

Further, in order to vary the fixed wing 17 fixed to the inner surface of the inner casing 11 while the inner casing 11 is rotatable, a different structure from that of the conventional fixed wing adjuster is required. And a fixed-wing varying means (16) coupled to the slide rotating body (14) and the slide rotating body (14).

The slide rotation body 14 is slidably fixed to the outer surface of the inner casing 11 so that the slide rotation body 14 is rotatable separately from the inner casing 11 and the slide rotation body 14, The inner casing 11 can be rotated independently of each other. That is, the slide rotation body 14 and the inner casing 11 can be rotated in the same or opposite directions with respect to each other at the same speed or at different speeds with respect to each other.

A second gear groove 141 is formed on the outer surface of the slide rotating body 14 so as to rotate the slide rotating body 14 independently of the inner casing 11 and the second gear groove 141 is formed in the second gear groove 141 The second rotary machine unit 15 is gear-coupled to the second rotary machine unit 15, and the second rotary machine unit 15 is rotationally driven by the second drive unit M2 such as an electric motor. Therefore, the rotation of the second driving means M2 causes the second rotary gear unit 15 to rotate, and the second rotary gear unit 15 is rotated by the rotation of the second rotary gear unit 15, The slide rotation body 14 itself can be rotated.

The inner casing 11 is also rotatably fixed to the fixed-point variable means 16.

The outer surface of the inner casing 11 may further include a slide groove 111 for slidably guiding the slide rotation body 14 so that the slide surface of the slide casing 14, The protruding portion 143 may be inserted into the slide groove 111 and slidably engaged with the protruding portion. Therefore, the slide rotating body 14 can be rotatably fixed independently from the inner casing 11 at a predetermined position without deviating from the outer surface of the inner casing 11.

The fixed-point variable means 16 is provided with a second gear portion 161 on its upper peripheral surface and also includes a variable shaft 162. The variable shaft 162 is inserted through the through hole 112 formed in the inner casing 11 so that the fixed blade varying means 16 including the variable shaft 162 is inserted into the inner casing 11 And the entire fixed-wing varying means 16 can revolve at the same speed as the rotation speed of the inner casing 11 when the inner casing 11 is rotated. The fixed-end variable means 16 further includes a second gear portion 161 that is gear-engaged with the first gear portion 142 of the slide rotation body 14, The second gear portion 161 can be driven by the first gear portion 142 by the gear engagement of the second gear portion 161. [ Accordingly, the second gear portion 161 can be rotated in proportion to the rotational speed of the slide rotating body 14 when the slide rotating body 14 rotates.

The at least one fixed wing 17 is hingably fixed to the inner surface of the inner casing 11 and the hinged fixing of the fixed wing 17 is fixed to the end of the variable shaft 162 of the sliding rotation body 14 Thereby fixing the fixed wing 17. Therefore, the fixed wing 17 can be varied by the fixed wing varying means 16. [

The inner casing 11 and the slide rotating body 14 are rotated at the same speed so that the speed difference between the inner casing 11 and the sliding rotating body 14 So that the fixed-wing varying means 16 rotatably fixed to the inner casing 11 does not revolve around the variable shaft 162 and only the idle motion with the inner casing 11 . Therefore, the fixed wing 17 integrally fixed to the end of the variable shaft 162 is not rotated about the variable shaft 162, and thus the angle or the like is kept unchanged.

In other words, when the inner casing 11 and the slide rotating body 14 rotate at different speeds, the speed difference between the inner casing 11 and the slide rotating body 14 is generated, As a result, the fixed-point varying means 16, which is rotatably fixed to the inner casing 11, revolves around the variable shaft 162 and performs idle motion together with the inner casing 11. Therefore, the fixed wing 17 integrally fixed to the end of the variable shaft 162 is rotated about the variable shaft 162, and thus the angle or the like is varied. 3 and 4, when the slide rotating body 14 rotates at a higher speed than the inner casing 11, the fixed-blade varying means 16 may rotate the slide- The inner casing 11 is rotated together with the imaginary central axis of the inner casing 11 so as to revolve around the variable shaft 162 and to the first gear portion 142 of the slide rotating body 14, The fixed worm 17 is rotated by the rotation of the coupled second gear portion 161, in particular, in the counterclockwise direction around the variable shaft 162, thereby integrally fixed to the variable shaft 162, Is also varied counterclockwise. Accordingly, by appropriately adjusting the relative speed of the inner casing 11 and the slide rotating body 14 relative to each other, the inner casing 11 can be rotated as a whole and at the same time, the angle of the fixed wing 17 can be varied The variable angle of the fixed wing 17 controls the direction of the blast furnace gas passing through the inner casing 11 to concentrate the blast furnace gas toward the rotor blades fixed to the rotating shaft S, Can be achieved.

A plurality of the fixed wings 17 may be provided and the number of the fixed wings 17 may be the same as the number of the fixed wings 17 or a smaller number of the through holes 112 may be formed in the inner casing 11, The number of the fixed teeth variable means 16 is set to be equal to or smaller than the number of the through holes 112 and these fixed tooth variable means 16 are connected to the first gear portion and the second gear portion It is possible to couple the plurality of fixed wings to the same angle by connecting them by gear coupling between the gear portions.

Although not explicitly shown in the drawings, a blast furnace constant-pressure generator turbine including a rotatable inner casing according to the present invention includes the inner casing to prevent leakage of blast furnace gas to the outside, The outer casing may further include an outer casing.
