Description

The field of technology

The invention relates to a fuel supply device, such as a burner, for introducing fuel, such as coal dust, from blast furnace nozzles into the furnace.

Prior art

In order to reduce the amount of coke used, fuel such as coal dust or heavy liquid fuel is introduced from blast furnace nozzles to provide combustion in the furnace. Fuel, such as coal dust, is injected with a stream of hot air into the blast furnace by a pulverized coal burner (hereafter referred to simply as the "burner") that passes through a blowdown pipe attached to each blast furnace.

A conventional burner is made, for example, of stainless steel or other special metal material with high heat resistance, since the burner is exposed to high temperatures. Unfortunately, the use of such a burner is still associated with problems, for example, with temperature deformation of the nozzle pipe, which can lead to damage to the nozzle or a decrease in combustion efficiency. In order to avoid these problems, a conventional burner requires replacement of the damaged lance tube after each deformation, resulting in increased lance tube consumption. In addition, the replacement of the burner must be carried out when the supply of hot air is reduced, with the operation of the blast furnace suspended. These requirements lead to an increase in costs.

In order to solve the above-mentioned problems, in the patent document UR 5105293 (RTI 1), the lance pipe is disclosed, which will probably be deformed and can rotate relative to the axis with a slight decrease in the spring force. Such a burner nozzle tube can be suitably rotated at the very beginning of temperature deformation in a sealed state, so that the deformed part of the nozzle tube moves to another position. Such rotation can prevent further deformation of the deformed part of the lance pipe and ensure that the pipe remains in a practically straight shape for a long period of time, and thus effectively prevent damage to the lance and avoid reduction in combustion efficiency.

Disclosure of the invention

General maintenance of a blast furnace requires stopping the air injection for a period of 12 to 72 hours once a month or every two months. Production regulation

The blast furnace also requires suspension of air injection. When air injection to the blast furnace is stopped, the flow of high-temperature hot air and fuel, such as coal dust, into the blast furnace also stops. In addition, maintenance of the burner is also carried out with suspension of air injection to the blast furnace. In more detail, the burner is disconnected from the blast furnace blast pipe, and then the lance pipe is disconnected from the burner flange. Unfortunately, the lance tube exposed in RTI 1 is made together with an adapter and bushing and therefore disconnects from the flange together with the adapter. Such disconnection leads to the opening of the sealing surfaces between the flange and the adapter (in particular, the inclined surface on the outer periphery of the front end of the adapter and the inclined surface on the inner periphery of the rear end of the cylinder screwed into the flange). Dust particles and scratches can form on the exposed sealing surfaces, which can lead to gas leaks and the passage of dust particles from the gap between the sealing surfaces during blast furnace operation. These problems force the operators to pay a lot of attention to the maintenance of the burner, which leads to a significant increase in the workload of the personnel.

Taking into account the above-mentioned problems, the task of the invention is to create a fuel supply device that ensures the preservation of the practically straight shape of the pipe for a long period of time and effectively prevents the possibility of damage to the tuyere and a decrease in the combustion efficiency in the blast furnace. Replacing a failed pipe with a new one in the fuel supply device according to the invention can be carried out without opening the sealing surfaces between the cylinder, which is attached to the mounting part (for example, the flange) of the discharge pipe of the blast furnace and the rotary element installed inside the cylinder, which provides a reduction staff workload.

The fuel supply device according to the invention contains a cylinder that is attached to a mounting part, such as a flange of a discharge pipe of a blast furnace; a hollow rotary element rotatably mounted in a cylinder having a base through which fuel is supplied to the internal cavity of the rotary element; a pipe installed with the possibility of disconnection at the end of the rotary element adjacent to the blast furnace and having a front end through which fuel enters the blast furnace; and a retainer removably attached to the cylinder that holds the rotary member in the cylinder, wherein the cylinder has an inner periphery that includes a first sealing surface, the rotary member has a second sealing surface and, when the rotary member is located in the cylinder, the second sealing surface comes into contact with the first sealing surface, providing a seal.

In the fuel supply device according to the invention, the pipe is attached with the possibility of disconnection to the end of the rotary element, which is adjacent to the blast furnace, and is installed with the possibility of rotation in the cylinder. At the very beginning of the temperature deformation of the pipe, it can be appropriately turned in a sealed state, so that the deformed part of the pipe moves to another position. Thus, the pipe can maintain an almost straight shape for a long period of time, which effectively prevents damage to the blast furnace tuyere and reduced combustion efficiency. In addition, in the fuel supply device according to the invention, only the pipe can be replaced without opening the sealing surfaces between the cylinder, which is attached to the locking part (for example, the flange) of the discharge pipe of the blast furnace and the rotary element installed inside the cylinder, which ensures a reduction of the working load per staff

Coal dust, spent plastic, gaseous hydrogen or heavy liquid fuel can be used as the fuel supplied to the rotary element of the fuel supply device according to the invention.

The fuel supply device according to the invention may additionally contain an elastic element that presses the second sealing surface of the rotary element to the first sealing surface of the cylinder.

The elastic element can be a spring, and the second sealing surface of the rotary element can be pressed against the first sealing surface of the cylinder by the force of the compressed spring.

In the fuel supply device according to the invention, the cylinder may contain a first connecting part on the inner periphery, and the latch may contain a first connecting part that is releasably engaged with the first connecting part.

In the fuel supply device according to the invention, the tube may include a base having a second connecting portion, and the pivot member may include a second connecting portion that engages with the second connecting portion.

The fuel supply device according to the invention may additionally contain a control part that is attached to the rotary element and is designed to rotate the rotary element.

The fuel supply device according to the invention may additionally contain a locking mechanism, which ensures the locking of the lock relative to the cylinder, in the state when the lock and the cylinder are connected to each other.

Next, the designs of the blast furnace 1, to which fuel, such as coal dust, is supplied from the fuel supply device 10 according to the invention, are described, with reference to Fig. 1. Blast furnace 1 is a vertically located cylindrical structure, the outer surface of which is covered with sheet steel, and the inner surface is lined with refractory material. The blast furnace 1 contains approximately 20 to 50 lances 2, which radially protrude from the side surface of the blast furnace. Streams of hot air coming from the blast furnace air heaters (coopers) C and through the discharge pipe 4, through the nozzles 2, enter the blast furnace 1. The nozzles 2 are made of copper and equipped with a water cooling system. Under the tuyeres 2 there are separate holes for draining molten iron and liquid slag. The fuel supply device 10 (pulverized coal burner) according to the invention is designed to introduce fuel, such as coal dust, to the blast furnace 1 through the nozzles 2. In more detail, each nozzle 2 of the blast furnace 1 contains a purge pipe and a pipe 20 (described below) of the device 10 fuel supply, located inside the blowdown pipe, so that the front part of the pipe 20 protrudes from the nozzle 2 into the inner cavity of the furnace.

Further with reference to Fig. 2-6 will describe the design of the fuel supply device 10 (pulverized coal burner) according to the invention. The fuel supply device 10 according to the invention includes a cylinder (sleeve) 30, which is attached to a mounting part, such as a flange (not shown), of the blast pipe 4 of the blast furnace 1, a hollow rotary element (adapter) 40, mounted rotatably in the cylinder 30 and which has a base through which the fuel enters the inner cavity of the rotary member 40, a pipe (turbine pipe) 20 detachably mounted at the end (that adjacent to the blast furnace 1) of the rotary member 40 and having a front end, through which the fuel enters the blast furnace 1, and the retainer 60, which is removably attached to the cylinder 30 and which holds the rotary element 40 in the cylinder 30. A spring 50 is installed in the cylinder 30, which performs the function of an elastic element that presses the second sealing surface 44 (see below) of the rotary element 40 to the first sealing surface 34 (see below) of the cylinder 30.

The control part 70 is designed to rotate the rotary element 40 and is attached, for example, by welding, to the rotary element 40. These components of the fuel supply device 10 are described in detail below.

The tube (lance tube) 20 is a long, thin tube made of a heat-resistant material, for example, stainless steel. periphery (see Fig. 3). The front part (adjacent to the blast furnace 1) of the hollow rotary element 40 (see below) contains an internal thread 42 (the second connecting part), for example, a threaded hole for the inner periphery. The external thread 22 of the pipe 20 is screwed into the internal thread 42 of the rotary element 40. Thus, the pipe 20 is attached with the possibility of disconnection to the end of the rotary element 40, which is adjacent to the blast furnace 1. The attachment of the pipe 20 to the rotary element 40 provides connection of the inner cavity of the pipe 20 with the inner space of the rotary element 40.

At the end of the cylinder, the one adjacent to the blast furnace 1, several protrusions (for example, three protrusions) 32 are formed, which radially protrude from the outer periphery of the cylinder or sleeve 30. These protrusions 32 provide the possibility of attaching the cylinder 30 to a mounting part, such as a flange (not shown) discharge pipe 4 of blast furnace 1. These protrusions 32 of cylinder 30 are inserted into the holes of the mounting part and then turned to attach the cylinder 30 to the discharge pipe 4 of blast furnace 1. Instead of inserting and turning the protrusions 32 into the holes of the mounting part, the cylinder ZO can be attached to the discharge pipe 4 of the blast furnace 17 with the help of locking elements, such as cotter pins. Several rods 38 (for example, four) radially depart from the outer periphery of the cylinder 30. Cylinder. 30 contains the first sealing surface 34, which runs along the entire inner periphery. The first sealing surface 34 is made with an inclination in the longitudinal direction (that is, horizontally in Fig. 3 and 4) of the cylinder 30. The cylinder 30 contains two locking holes 39 located near its base (which is remote from the blast furnace 1). The latch 60, which engages with the cylinder 30, is attached to the cylinder 30 using a locking pin or rod 66, which is inserted into the locking holes 39 (see Fig. 5 and b).

As shown in Fig. With and 4, the hollow rotary element (adapter) 40 on its outer periphery contains a second sealing surface 44 located inside in the longitudinal direction. When inserting the rotary element 40 into the cylinder 30, the second sealing surface 44 comes into contact with the first sealing surface 34, providing sealing. The second sealing surface 44 is made with an inclination in the longitudinal direction (that is, horizontally in Fig. 43 of the rotary element 40. Tight contact of the second sealing surface 44 of the rotary element 40 inserted inside the cylinder 30 with the first sealing surface 34 of the cylinder 30 forms a seal, which prevents the escape of gases and dust from the gap between the cylinder 30 and the rotary element 40. The base (remote from the blast furnace 1) of the rotary element 40 is attached, for example by welding, to the control part 70 (see below). The rotary element 40 can rotate inside the cylinder 30 using the control part 70.

A retainer 60 is removably attached to the base (remote from the blast furnace 1) of the cylinder 30. Attached to the cylinder 30, the retainer 60 holds the rotary element 40 inside the cylinder 30. In more detail, the retainer 60 contains an external thread 62 (the first connecting part), such as a threaded protrusion on the outer periphery of the front part (which is adjacent to the blast furnace 1), as shown in Fig. 4 and 5. The cylinder 30 has an internal thread 36 (the first connecting part), such as a threaded hole on the inner periphery of the base part.

The external thread 62 of the latch 60 is screwed into the internal thread 36 of the cylinder 30. Thus, the latch 60 is attached with the possibility of disconnection to the base of the cylinder 30. After connecting the latch 60 to the cylinder ZO, the locking pin 66 is inserted into the two locking holes 39, and the latch 60 turns out to be attached to the cylinder 30, as shown in Fig. 6. In this version, the locking holes 39 and the locking pin 6b perform the function of a locking mechanism, with the help of which the lock b6O, which is included in the cylinder Z0, is fixed relative to this cylinder 30.

As shown in Fig. 3, a spring 50 is installed around the rotary element 40 in the cylinder 30. One end of the spring 50 is in contact with the retainer 60. When the rotary element 40 and the spring 50 are inserted into the cylinder 30 and the retainer 60 is connected to the base of the cylinder 30, the spring 50 is in a compressed state . The generated force of the spring 50 moves the rotary element 40 in the direction to the left in Fig. 3. Thus, the second sealing surface 44 of the rotary element 40 is pressed against the first sealing surface 34 of the cylinder 30, and a tight contact is formed between these two surfaces. In other words, the spring 50 performs the function of an elastic element that presses the second sealing surface 44 of the rotary element 40 to the first sealing surface 34 of the cylinder 30. Such a spring 50 forms a tight

From the contact between the second sealing surface 44 and the first sealing surface 34, more effectively preventing the leakage of gases and dust particles from the gap between the first sealing surface 34 and the second sealing surface 44.

The control part 70 is hollow; it is attached (for example, by welding) to the base (remote from the blast furnace 1) of the rotary element 40. The inner cavity of the control part 70 is connected to the general cavity of the rotary element 40. The control part 70 contains the drive part 72, which has a cross-section of polygonal (for example , hexagonal) shape. For example, the driving part 72 is clamped with a chain or large pliers (not shown) to turn the control part 70 so that the pipe 20 and the rotating member 40 turn in the cylinder 30 attached to the setting part, for example, to the flange of the discharge pipe 4 of the blast furnace 1 .The control part 70 may be connected to a fuel supply hose 80, which supplies fuel, such as coal dust, into the inner cavity of the control part 70. The control part 70 may be directly connected to the hose 80 or may be connected to sleeve 80 with the help of a hollow pipe. Alternatively, the control part 70 can be connected to the sleeve 80 by means of a valve. The control part 70 can be directly connected to a flexible sleeve through which fuel is supplied to the inner cavity of the control part 70.

Next, the assembly process of the fuel supply device 10 will be described with reference to Fig. 4-6.

For simplicity of description, pipe 20 and sleeve 80 in FIG. 5 and 6 are not shown.

At the beginning of assembly of the fuel supply device 10, the rotary element 40 and the spring 50 are inserted into the cylinder 30, so that the spring 50 is located around the rotary element 40. In Fig. 5 shows a cylinder 30 with a rotary element 40 and a spring 50 inserted into it. Then a retainer 60 is attached to the base of the cylinder 30 to prevent the rotary element 40 and spring 50 from being disconnected from the base of the cylinder 30 and these elements coming out. In more detail, for this, the external thread 36 of the retainer 60, such as a threaded protrusion, is screwed into the internal thread 36, such as a threaded hole, of the cylinder 30. After attaching the retainer 60, the control part 70, connected to the fuel supply hose 80, is attached, for example, by welding, to the base of the rotary element 40. In Fig. 6 shows a cylinder 30 with a retainer 60 attached to the base of the cylinder 30. At the final stage of the assembly process, the base of the pipe 20 is attached to the front end of the rotary element bo 40. In more detail, for this, the external thread 22 of the pipe 20 is screwed into the internal thread 42,

such as the threaded hole of the rotary element 40. Thus, by means of the process described above, the assembly of the fuel supply device 10 shown in Fig. 2 and 3.

Next, it is revealed how the fuel supply device 10 is used. Before starting to supply fuel, for example, coal dust, to the blast furnace 1 using the fuel supply device 10, the protrusions 32 of the cylinder 30 are attached to the mounting part, for example, to the flange of the injection pipe 4 of the blast furnace 1, so that the pipe 20 of the supply device 10 fuel is inserted into the blow pipe of blast furnace 2 blast furnace 1, and the front end of pipe 20 protrudes from blast furnace 2 into the inner cavity of the blast furnace. Fuel, such as coal dust, is fed through the fuel supply sleeve 80 into the inner cavity of the control part 70, so that the fuel successively passes through the inner cavity of the control part 70, the inner cavity of the rotary member 40 and the inner cavity of the pipe 20 and through the front end of the pipe 20 is introduced into the inner space of the blast furnace 1.

After long-term operation of the pipe 20 of the fuel supply device 10, the pipe 20 may be deformed due to the influence of thermal energy, as shown in Fig. 7, which leads to the risk of contact of the pipe 20 with the nozzle 2 or any other components. To eliminate such a risk, according to the invention, the pipe 20 and the rotary element 40 can be turned with the help of the control part 70 at the very beginning of the temperature deformation of the pipe 20, thus changing the position of the front end of the pipe 20 exposed to high temperatures. This specified rotation of the pipe 20 ensures a uniform supply of heat along the entire periphery of the pipe 20, preventing deformation in the form of bending of the pipe 20 in any one direction under the influence of the own weight of the pipe 20 under conditions of exposure to high temperatures.

Next, the maintenance process of the fuel supply device 10 will be described. The fuel supply device 10 according to the invention requires replacement of the pipe 20 from time to time, since the pipe 20, and in particular, its front end, is subject to thermal deformation during the operation of the blast furnace 1.

Since the pipe 20 is detachable from the pivot member 40, replacing the pipe 20 does not require disconnection of the retainer 60 from the cylinder 30. Only the pipe 20 can be detached, while the pivot member 40 can remain in the cylinder 30. In other words, the pipe 20 can be replaced with a new one when the first sealing surface 34 of the cylinder 30 is in tight contact with the second sealing surface 44 of the rotary element 40. Such

The design prevents the deposition of dust particles on the first sealing surface 34 and the second sealing surface 44 and the formation of scratches on these surfaces.

The rotary element 40 of the fuel supply device 10 according to the invention wears out and needs to be replaced with a new one, as a rule, about once a year. Since the latch 60 can be disconnected from the cylinder 30, replacing the rotary element 40 requires disconnecting only the latch 60 from the cylinder 30. This design eliminates the amount of work of the installation personnel associated with the replacement of the cylinder 30.

In the fuel supply device 10 of the above-described design in accordance with the invention, a hollow rotary element 40, through the base of which fuel is supplied to the internal cavity of the system 10, is installed with the possibility of rotation in the cylinder 30, the pipe 20, which supplies fuel to the blast furnace 1, is attached with the possibility of connection, to the end (that adjacent to the blast furnace 1) of the rotary element 40, and the latch 60, which holds the rotary element 40 in the cylinder 30, which is attached to the cylinder 30 with the possibility of disconnection. At the very beginning of the temperature deformation of the pipe 20, this pipe 20 can be appropriately turned in a sealed state, so that the deformed part of the pipe moves to another position. Thus, the pipe 20 can maintain an almost straight shape for a long period of time, which effectively prevents damage to the tuyeres 2 of the blast furnace 1 and a decrease in combustion efficiency. In addition, the replacement of the pipe 20, which does not require opening the sealing surfaces (in particular, the first sealing surface 34 and the second sealing surface 44) between the cylinder 30 attached to the mounting part, such as the flange of the discharge pipe 4 of the blast furnace 17, and to the rotary element 40 , can reduce the amount of work of the installation personnel. In other words, the latch 60 performs the function of a protective cover of the first sealing surface 34 and the second sealing surface 44.

As mentioned above, in the fuel supply device 10 according to the invention, the fuel that is fed into the inner cavity of the rotary element 40 is coal dust. However, coal dust is only a non-limiting example of a fuel that can be fed into the inner cavity of the rotary element 40; other types of fuel, for example, waste plastic, hydrogen gas, or heavy liquid fuel can also be fed into the inner cavity of the rotating element 40.

As mentioned above, in the fuel supply device 10 according to the invention, the spring 50 performs the function of an elastic element that presses the second sealing surface 44 of the rotary element 40 to the first sealing surface 34 of the cylinder 30. In more detail, the force created by the spring 50 in compressed state, presses the second sealing surface 44 of the rotary element 40 to the first sealing surface 34 of the cylinder 30.

Since the first sealing surface 34 is in closer contact with the second sealing surface 44, which more effectively prevents the leakage of gases and dust particles from the gap between the first sealing surface 34 and the second sealing surface 44. In the fuel supply device 10 according to the invention, the pressing of the second sealing surface 44 of the rotary element 40 to the first sealing surface 34 of the cylinder 30 can be carried out by any other element, except for the spring 50. To press the second sealing surface 44 of the rotary element 40 to the first sealing surface 34 of the cylinder 30, any other type of pressure can also be used element (for example, an elastic element of the flat spring type).

In the fuel supply device 10 according to the invention, the cylinder 30 includes an internal thread 36 as the first connecting part along the inner periphery, and the latch 60 includes an external thread 62 as the first connecting part that engages with the internal thread 36 as described above . The first connecting part and the first connected part can have any other design, which differs from the internal thread 36 and the external thread 62, in the corresponding fuel supply device 10 according to the invention. As the first connecting part and the first connecting part, which can attach the latch 60 to the cylinder 30, any other designs can also be used.

In the fuel supply device 10 according to the invention, the pipe 20 contains an external thread 22 and as a second part connected to the base, the rotary element 40 contains an internal thread 42 as a second connecting part, which can be engaged with the external thread 22, as was described above. The second connected part and the second connected part can have any other design, which differs from the external thread 22 and the internal thread 42, in the corresponding device 10 of fuel supply according to the invention. As the second connecting part and the second connecting part, which can attach the pipe 20 to the rotary element 40, any other designs can be used.

In the fuel supply device 10 according to the invention, the control part 70 is designed for

From the rotation of the rotary element 40, attached to the rotary element 40, as described above. Such a control part 70 enables the operator to easily turn the rotary element 40 located in the cylinder 30, which is attached to the mounting part of the discharge pipe 4 of the blast furnace 1, and thus easily turn the pipe 20.

In the fuel supply device 10 according to the invention, the locking holes 39 and the locking pin 6b function as a locking mechanism for attaching the locking device 60, which engages with the cylinder 30, to the cylinder 30, as described above. Such a locking mechanism prevents disconnection of the lock 60 from the cylinder 30 during operation of the fuel supply device 10.

The above-described embodiment of the invention should not be considered as limiting the scope of the invention, and various changes may be made to the design of the fuel supply device 10.

For example, the spring 50 installed around the rotary element 40 located inside the cylinder 30, as mentioned above, may not be included in the design. In addition, the rotation of the rotary member 40 can be carried out by any other means other than the control part 70.
