Description

[0001] SINTER COOLER [0002]

The present invention relates to a sintered-light cooler and a cooling method for sintered ores for backflow operation.

Sintering machines are generally used to aggregate fine particles by a sintering process in which porous materials are typically formed from the particles while maintaining their chemical properties. The sintered ores, which are the products of the sintering process, can be used in subsequent processes. For example, in steel production processes, it is known to be produced from iron ores and other particles. The sintered ores are then used in the furnace. After the sintering process, the sintered light initially having a high temperature of 600 ° C to 700 ° C is cooled to a suitable temperature of, for example, 100 ° C in the sintering cooler.

In a general form of sintered light cooler, the hot sintered organs are gravitized into the shaft through the upper filler. At the lower end of the shaft, the sintered ores can be extracted through a discharge port, for example, by a scraper. While the sintered ores come down through the shaft, the cooling gas (typically air) is guided through it to cool the sintered light and to raise the temperature of the gas. On the other hand, the heated gas for the heat recovery process can be used, for example, to recycle the sintering machine and / or to generate steam which can drive the generator.

In a cross-current shaft-type cooler, the cooling gas mainly flows in the horizontal direction. In the counter-current cooler, the general movement of the cooling gas is upward in the sintering direction in the vertical direction, Move. These coolers are very effective in the heat exchange between the sintered light and the gas. The gas enters the lower portion of the shaft and is sucked into the upper portion of the shaft, where it can be guided to some heat recovery means. The general form of a sintered light cooler has a circular shaft in which sintered light is received and cooled, while the shaft itself is rotatably mounted. During operation, the shaft is rotated and other parts of the shaft are sequentially filled with the sintered ores by the filling device. The air inlet vanes are arranged in a tangential direction at the lower portion of the inner and outer walls of the shaft. The hermetically sealed hood is located at the top of the shaft and is connected to an air inlet fan or the like.

In particular, when a new sintered light cooler is installed in a conventional sinter ore plant, the main purpose is to minimize the size of the cooler, since typically the available space is very limited. Since it is not economically feasible to stop the long term operation of the sinter plant, during the installation of a new cooler, a conventional sinter cooler should generally remain in operation.

On the other hand, even if the size of the cooler is reduced, the required air flow rate should not be changed due to the requirement of the cooling process, which is defined by the amount of sintered light to be cooled, according to the specific air-to-sintered ratio (y ton of air / . If a given amount of wind is guided through a smaller cooler, the air velocity increases accordingly. This causes problems because the pressure drop in the sintered bed increases excessively with increasing air velocity. On the other hand, since the pressure drop is proportional to the electrical consumption of the air intake fan, the operating cost in the sinter or quartz cooler is highly dependent on the pressure drop in the sintered orbital bed. Therefore, in order to avoid an increase in the operating cost due to the decrease, the air velocity through the sintering bed and the resulting pressure drop should be kept as low as possible.

One means for solving this is to increase the horizontal cross section of the shaft. This is achieved by reducing the inner diameter of the shaft, i.e., by making the shaft wider while maintaining the outer diameter. Although air velocity - and thus pressure drop - is reduced by these dimensions, air distribution is an important issue. In a typical cooler of the type described, the air inlet vanes are integrated in the inner wall of the shaft and the lower portion of the outer wall. This is where the cooling air passes through the shaft. In the case of narrow shafts (up to 1 mm width), for example, after any inflow section of 1 m, the air is evenly distributed throughout the section of the shaft. In the case of a wide shaft (e.g., 1.5 m wide or more), due to the distance from the air inlet vane to the center of the shaft is long and any barrier effect (e.g., preferred flow along the shaft wall) Mixing takes a very long time. However, the distribution of the uneven cooling air disturbs the cooling process, i.e. the sintered light is not effectively cooled and / or the air is not optimally heated.

In order to solve this, it has been proposed to provide a ventilation tube radially arranged in the lower part of the shaft, communicating with an additional tangential inlet vane in the center of the inner and outer walls. This arrangement improves the supply of cooling air to the interior region of the shaft, while the additional components are relatively complex and also susceptible to high wear forces and limited lifetime. This is because the shaft is generally tapered downward to increase the speed of the sinter at the lower part.

It is an object of the present invention to provide a sintered orbiter cooler in which a very uniform airflow appears, while avoiding additional wear. This object is achieved by the sintering-type cooler according to claim 1 and the method according to claim 12.

The present invention provides a sintering-type cooler for a reverse flow operation. Reflux operation means that cold gas, in general, flows inversely to the general flow for the motion of the air-cooled sinter. However, this may include smaller regions where the airflow is oblique or perpendicular to the motion of the sintered ores. As described above, such a sintered-light cooler is part of an integrated sintering plant and is used to cool the hot sintered ores from a high temperature to a low temperature, or at least to a suitable temperature. Hereinafter, reference will generally be made to "air "," air flow ", although other gases may be used within the scope of the present invention.

The cooler has a circular shaft for receiving sintered light, and the shaft has at least one top filling port and at least one bottom outlet. The shaft is circular. That is, the shaft generally has a ring-shape (annular) and is at least approximately symmetrical about the axis. The shape may not correspond to the complete ring, but may be a ring with a polygonal cross section, which is also considered herein as "circular ". The circular shape of the shaft and the aforementioned axis define the radial and tangential directions described above or below. Generally, the shaft is rotatably mounted, and a portion of the shaft is placed in a filling apparatus supplied by an sintering machine. The filling device supplies sintered light to a portion of the shaft, which rotates about the axis of symmetry - continuously or intermittently - to cause the sintered orbit to fill all parts. The hot sintered ores are supplied through at least one blue sphere, and the cooled sinter ores are extracted (or simply dropped) at the outlet. As described above, the upper portion of the shaft is covered by a sealed hood which is connected to the air suction device. Generally, the cooler is suitable for forming negative pressure in or on the upper portion of the shaft.

According to the invention, in the lower part, the shaft is divided into a plurality of sections, the sections being tangentially spaced. The meaning of the tangential direction means the direction of tangency defined by the circular shape of the shaft.

In the upper part, the shaft in the vicinity of the filler preferably has a single continuous structure along the tangential direction (i.e., the wobbling direction) and the lower part is divided into sections. That is, the shaft is divided downward into a plurality of sections spaced along the tangential direction. Thus, the shape of the shaft in this lower portion is not continuous, but the overall shape of the shaft is still circular. The section of the compartment may be, for example, circular, polygonal or another shape.

Each compartment has at least one sidewall having radially extending radial inlet vanes for introducing cooling air into the shaft. Since the sections are spaced apart, each section is defined by the side walls. The radial inlet vane is installed on at least one side wall. Generally, the vanes are arranged such that the sintered ores can not escape from the vanes due to gravity. That is, the vane guides the sintered ores to stay in the compartment. The vanes extend radially, and are preferably arranged in a radial direction. However, the vanes may also have, for example, a bent shape that does not completely correspond to the radial direction, or an oblique to the radial direction. In any case, one end of each vane is disposed radially outward from the other end.

During operation, the sinter cooling cooler is set as follows. The sintered ores are filled through the filler and moved downwardly through the compartment to the outlet, while cooling air is drawn through the radial inlet vane and moved up through the shaft. That is, as the movement of gravity of the sintered light passes through the compartment, the sintered light is divided among the compartments. The radial inlet vane directs the air flow from the tangential direction into the sinter ores. In addition, the air flow acts directly on the radially extended regions of the compartment and inside the sintered ores. Whereas in the prior art, tangentially arranged inlet vanes forming only radially inhomogeneous air flow are contemplated, the present invention provides significantly improved uniformity. Compared to designs that rely on additional air ducts in the lower portion, the present invention is simpler and minimizes wear.

In order to ensure a large inflow area of the cooling air, the radial inlet vane preferably extends at least 50% of the radial width of the compartment. More preferably, the radial inlet vanes extend at least 70%, more preferably at least 90% of the radial width of the compartment. In one embodiment, the sidewall of the compartment may be open to allow air to be drawn into a larger portion of the compartment, such that the airflow is highly uniform along the radial direction. The radial inlet vane may also be provided over the entire radial width.

Because the compartments are spaced apart, there is a space between adjacent compartments, and the cooling air from the spaces is sucked into each compartment. The cooling air can flow into this space, for example, from radially inward and / or outwardly.

In one embodiment, this space has a lower-side opening so that cooling air can flow into the space from below. In fact, there is no need to have a bottom plate or the like between the sections. That is, since the sintered light can not pass through the space from under by gravity, the inner space can be completely opened to the lower surface.

In one embodiment, in particular, when the tangent width of the individual compartments is relatively wide, the invention can be improved by having each compartment having at least one side wall with a tangential inlet vane extending in a tangential direction. Such tangential inlet vanes known in the art may be disposed on the radially inner and / or outer wall of the compartment.

The tangential vanes are preferably arranged in a tangential direction. However, the tangential vanes may, for example, have a bent shape that does not completely correspond to the radial direction, or may be oblique to the radial direction. Preferably, the tangential vane extends at least 50%, more preferably at least 70%, and even more preferably at least 90% of the total tangential width of the compartment. It should be noted that, if the radial tangential vanes extend over the entire width of the section, the vanes are connected or formed as a unitary body. In this case, there may be a kind of "circumferential" vane constituting the tangential and radial vanes.

According to an exemplary embodiment of the present invention, the radial width of the shaft decreases as it is lowered. That is, the wall of the shaft is inclined inward. In this embodiment, in keeping with the typical cooler design described above, the velocity of the sintering light going down increases towards the lower portion, thereby increasing the risk of wear stress. In this case, the invention is particularly advantageous because no additional air duct or the like is required in the lower part of the shaft.

Further, it is preferable that the width in the tangential direction of each partition decreases as it goes down. That is, the side walls of each of the compartments are inclined inward. This, on the other hand, increases as the space width between neighboring compartments decreases and is relatively narrow at the top. Thus, the sidewalls of the two neighboring compartments form a somewhat roof-like structure, which helps smoothly deflect the sintering light down into the individual compartments above.

Depending on the design of the shaft, the cooling air may have a tendency to move along the inner and outer walls that cause non-uniform airflow. One way to avoid this phenomenon is to provide at least one profile forming means. The profile forming means is adapted to concave the top profile of the sintered light radially. That is, the height of this profile along the radial direction is greater in the direction along which the inner wall and the outer wall are routed. That is, the length from the sintered orbital bed is shorter than the central region of the shaft, which means that the cooling air has a tendency to move away from the sidewalls towards the center. The profile forming means may be a scraper acting on the sintered ores from above. In the present specification, the rotation of the shaft can be utilized in that the profile forming means is stationary and can act like a plow forming a "furrow"

In this specification, in particular, the profile forming means is preferably adjustable. For example, the vertical position of the forming means can be adjusted or the profile itself of the forming means can be replaced. Generally, this adjustment can be made during a temporary shutdown of the facility. However, drive means may be provided so that such adjustment is made during operation.

As is known, the sintered light that flows into the cooler is composed of particles having different sizes. It is also well known that smaller size particles can be deposited more densely because the space for air between the particles is smaller. Thus, the region with larger particles leaves more space for the air to pass, which can be the preferred passage of cooling air. This effect can be utilized in another embodiment of the present invention having at least one dispensing means. The dispensing means are adapted to fill the sintered organs primarily towards the radially inner and radial outer walls of the shaft. In this area, the sinter ores will overflow and roll downhill.

 Here, larger particles are rolled farther than smaller particles and accumulate in the central region between the inner wall and the outer wall periphery. Thus, a "size gradient" is formed in the sintered orbital bed such that smaller particles are attached to the inner and outer walls and larger particles are at the center. Thus, the cooling air will preferentially pass through the center off the lateral force. It should be noted that similar effects can be formed by the above-described profile forming means. For example, if the forming means initially forms a profile that exceeds the repose angle of the sintered ores, this may cause the sintered particles to roll down the slope.

The air flow in the central region of the shaft can become more active. According to another embodiment of the present invention, at least one exhaust system is disposed in the upper portion of the shaft so as to be embedded in the sintered compact during operation, and is suited for sucking in air locally into the shaft.

The exhaust system is located at the top of the shaft, and the speed of the descending sintered light is not higher than the lower portion, so the wear is considerably low. Unlike the conventional suction means, the exhaust system is installed on the outer surface of the shaft and on the sintered orbital bed. The exhaust system is thus arranged to be embedded in the sintered ores during normal operation of the cooler. The exhaust system may include at least one air duct having at least one opening. The openings are generally (radially) disposed in the central region of the shaft. If the exhaust system is adapted to draw air into the shaft, an additional cooling air source may be provided in the central region, thereby improving cooling performance.

Another addition to improve the contact of sintered light and cooling air is to deflect the sintered light to move in the direction of the air flow, even though the airflow mainly occurs near the shaft wall. This can be done by a central deflecting element arranged in the shaft and can be adapted to deflect the sintered light radially from the radial central region of the shaft. Such a biasing element may be a circular beam arranged circumferentially in the shaft.

Alternatively, the deflecting element may be arranged at the bottom of the compartment. In either case, the deflecting element may have an oblique upper surface that forms a roof-like structure for optimal deflection of the sintered ores. At this time, the lower end of the deflecting element may be on the lower end of the compartment. That is, the deflection element need not extend completely to the end of the compartment. If the sintered light stream is divided by the deflecting element and is deflected toward the shaft wall and flows together under the deflection element, the backwash effect can be significantly improved.

The present invention also provides a method for cooling an sintered ores in a sintered light cooler having a circular shaft for receiving sintered ores. The shaft has at least one top filling port and has at least one bottom outlet. In the lower portion, the shaft is divided into a plurality of tangentially spaced apart compartments, each compartment having at least one side wall with radially extending radial inlet vanes for drawing cooling air into the shaft.

The method includes filling the sintered orifice through the fill port, moving the sintered orifice downwardly through the compartment to the outlet port, and cooling air being drawn through the radial inlet vane and upwardly through the shaft do.

The cooling method according to the preferred embodiment of the present invention is in conformity with the cooling method of the sintering cooler of the present invention.

1 is a perspective view schematically showing a shaft 2 of a sintered orbiter cooler 1 of the present invention. The shaft 2 generally has a circular or annular shape with an inner wall 3 and an outer wall 4. The shaft (2) has an upper filling port (5) extending circumferentially between the inner wall and the upper end of the outer wall (3, 4). In Fig. 1, a portion of the outer wall 4 has been removed to show the interior of the shaft 2. In the lower part (2.1), the shaft (2) is divided into a plurality of sections (7) with a discharge opening (6) at the lower end. During operation, the sintered ores 100 are filled into the shaft 2 through the filler 5, and are lowered by gravity and travel through the compartment to the respective outlet 6. The rotation of the shaft 2 with respect to the axis of symmetry ensures a uniform distribution of the sintered light 100.

As shown, all of the compartments 7 are defined by radially disposed side walls 8 facing the adjacent compartments 7. The side walls 8 of the neighboring compartments 7 are inclined inwardly to form a roof-like structure. A plurality of radial inlet vanes (9) are disposed in each side wall (8). The radial inlet vane extends at least about 80% of the radial width of the section (9). During operation, a negative pressure is applied on the upper part (2.2) of the shaft whereby air is sucked through the radial inlet vane (9) and the upper part (2.2) of the shaft . Thus, the air moves in the opposite direction to the descending sintered light 100.

In the illustration according to the embodiment, the tangential side wall 10 of the compartment 7 is completely closed and does not have an inlet vane. The radial vane 9 associated with the shaft 2, which is divided into a plurality of compartments 7, can have a sufficiently uniform air flow, thereby effectively cooling the sintered ores 100. In the drawing according to the embodiment, the shaft 2 is divided into 12 sections 7. Of course, the numbers may be different and may be as high as 20 or 50 in particular. In the figures according to the embodiment, the space 11 between the adjacent compartments 7 has a lower-side opening 12 and radially inner and outer openings 13. Further, the openings 12 and 13 may be one opening. However, at least one of the lower-side opening 12 or the inner and outer openings 13 may be omitted.

Fig. 2 shows a cross section of a part of a sintered light cooler 1 having a shaft 2 of Fig. As shown in more detail, the radial width of the shaft 2 decreases as it goes down. For structural stability, the inner shaft wall 3 is connected to the support structure 14 and the two shaft walls 3, 4 are connected by three connecting beams 15 arranged horizontally. During operation, a filling device (not shown) of the sintered light 100 facility is located on the shaft 2 and drops the sintered light 100 onto the shaft 2, Descend. A sealed hood connected to the air intake system is placed in the upper part (2.2) of the shaft (2). However, the above is not shown in Fig. Since the shaft is mounted on the rotating platform 16 and slowly rotates on the circular track, the stationary filling device is placed in another area of the shaft 2 in sequence. At the bottom outlet, a stationary stripper 17 is provided, which helps remove the cooled sintered ores 100 from the shaft 2. As shown in the drawings in greater detail, each compartment includes four inlet vanes 9 extending radially on both sides of at least about 80% of the width of the compartment 7. However, this is in one embodiment, the number of vanes 9 may be more or less than, and may be more or less.

3 is a perspective view of the shaft 2a according to the second embodiment of the present invention. Fig. 3 is much like part of the shaft shown in Figs. 1 and 2 and also has a section 7a with a radial inlet vane 9. Fig. However, Figure 3 additionally includes a tangential inlet vane 18 disposed on each section. In this embodiment, the radial and tangential inlet vanes 9, 18 extend about 80% or more of the width of each section 7a. However, it may extend beyond the entire width, so that the radial and tangential inlet vanes can form a substantially single-columnar inlet vane. The tangential inlet vane 18 increases the air intake area, thereby reducing the air flow rate during inhalation. In addition, the uniformity of the airflow is further improved, and in particular, the uniformity of the airflow is further improved in the lower portion of the shaft 2a having the section 7a.

FIG. 4 is a schematic view showing a cross section of a sintered-crystal cooler 1b according to a third embodiment of the present invention. The embodiment uses the shaft 2a of Fig. 3 with an inlet vane 18 in the inner and outer tangential directions. A deflecting beam 19 is applied to the (radially) central region of the shaft 2a to increase the backflow effect even if the air has a tendency to move along the side walls 3a, 4a of the shaft 2a. As shown in FIG. The deflecting beam 19 is disposed in the middle of the lower portion of the shaft 2a but slightly above the tangential inlet vane 18, for example, just above the section 7a.

Alternatively, a deflection beam may be provided in each section 7a. As shown in Fig. 4, the deflecting beam 19 is not completely extended in the downward direction of the shaft 2a, i.e., does not completely divide the lower portion. The function of the deflection beam is to divide the descending sintered light 100 into two flows (represented by a dark black arrow) and to bring the air upwards to be closer to the inner and outer walls. At some point below the deflecting beam 19, the two air streams are combined.

5 is a schematic view showing a cross section of a sintered-crystal cooler 1c to which the shaft 2a of FIG. 3 is applied according to a fourth embodiment of the present invention. Here, the sintered ores 100 are not uniformly filled along the radial direction, but are preferably directed to the inner and outer walls 3a, 4a. This is easily accomplished by a roof-shaped distribution element 21 located at the end of the chute of the filling device. The sintered ores 100 are piled up and begin to slip or slip down toward the middle region 20 of the shaft 2a. This process causes some separation by the tendency of larger particles to move more than smaller particles. However, since the larger particles leave more room for air to flow, the middle region 20 of the shaft 2a becomes the preferred flow path. Thus, the cooling air (indicated by the thick white arrow) is moved away from the side walls 3a, 4a and the shaft 2a is moved to the middle region 20.

6 is a schematic view showing a cross section of a sintered-crystal cooler 1d according to a fifth embodiment of the present invention. In this embodiment, the sintered light 100 is distributed over the entire radial width of the shaft 2a, but a scraper 22 acts at the top of the sintered ores 100 to form a concave profile. The scraper 22 is stationary and operates similar to a plow when the shaft 2a rotates. The concave profile means that the total height of the sintered orbital layer at the center of the shaft is smaller than the height of the inner and outer walls 3a and 4a.

In addition, the distance from the tangential inlet vane 18 to the center of the concave profile is reduced relative to the distance to the inner and outer ends of the profile. Thus, the cooling air (indicated by the thick white arrow) is directed at least partially back to the center of the shaft 2a at the side walls 3a, 4a. The separation effect described in the fourth embodiment can be generated to some extent in the fifth embodiment. On the other hand, also in the fourth embodiment, a concave profile can be formed.

7 is a schematic view showing a cross section of a sintered-crystal cooler 1e according to a sixth embodiment of the present invention. Here, an exhaust system is installed in the connecting beam in the center or upper region of the shaft. The exhaust system includes an air duct (not shown) that can be easily integrated or mounted in the beam 15 and an outlet 23 for discharging air into the shaft. In this embodiment, the air is sucked into the shaft by the same negative pressure that sucks air through the inlet vane 18, since the air duct is simply connected to the outside, i.e., atmospheric pressure. The supply of additional cooling air is thus provided in the upper part of the shaft, the flow of air through the center or upper part is increased and fresh cooling air is introduced into the part, while the rising air Is already heated to a certain extent. This central outlet 23 can provide additional cooling air to cool the sintered ore in the central region of the shaft.

Fig. 7 shows an exhaust system as a means for sucking air into the shaft 2a.

In Figures 4-7, the tangential inlet vane 18 is shown in perspective by the cutting direction through the shaft. The air is also sucked into the shaft through the radial inlet vane not shown in Figs. The embodiments of Figs. 4 to 7 are all effective in the embodiment without the tangential inlet vane, i.e. the embodiment with only the radial inlet vane.
