The disclosure of this case is fully incorporated herein by reference. As a reference. Field of invention

The invention relates to a flue structure of a coal coke drying and quenching equipment. More specifically, the present invention relates to a flue structure for a coal coke drying and quenching apparatus that contains micro particles and dust particles in an exhaust stream. The exhaust gas is heated by the hot coal in the cooling chamber of the coal coke drying and quenching equipment before being fed to the heat exchanger of the coal coke drying and quenching equipment, such as a boiler. tPrior art background 3 15

It is conventional to use coal coke drying and quenching equipment to cool the hot coal coke exchanged from a coal coke oven to recover the sensible heat that the hot coke has. In particular, the hot coal coke is fed in batches via a hopper to be stored in a preparation chamber, and then continues to fall in the cooling chamber. 20 The coal coke drying and quenching equipment according to the conventional art includes a hopper from the top to the bottom, a preparation chamber, an exhaust port, a cooling chamber, a blow port, and a coal coke release outlet. The hot coal coke released from the coal coke oven is fed into the preparation chamber through a hopper located at the top of the coal coke drying quenching equipment. After that, the coal coke was continuously dropped into the cooling chamber 5 200418973 located under the preparatory chamber, and was cooled to about 200 ° C after heat exchange with the inert gas blown from the blow port. The cooled coal coke is released from a cooling coal coke release port by a cooling coal coke releasing device. The inert gas stream is heated to heat to about 800 ° C with the hot coals. The inert gas stream then passes through an exhaust port to a ring duct, 5 and the following flue ducts and is then introduced into a boiler via a duct. Water is fed into the boiler through a water supply pipe to be heated, or it is converted into steam by being absorbed by the heat of the inert gas sent from the pipe. This hot water or steam is transported via a duct.

The inert gas stream contains solid particles and dust particles suspended in it. The micro particles, dust particles and inert gas flow to the boiler through the guide. The inert gas sent into the boiler may cause wear of the heat exchange tubes, resulting in the wear of the heat exchange tubes and / or the formation of sinkers of particles and dust particles. This may cause malfunction of the heat exchange tubes. In view of this, a dust particle separator can be assembled in the middle of the duct path to separate particles and 15 dust particles in the inert gas. The separated particles and dust particles are emitted through an ejection tube. The dust particle separator used in the duct includes a collision plate protruding in the flow path, which can intercept particles and dust particles suspended in the inert gas colliding with the collision plate. The dust separator has the advantage of reducing the maintenance workload due to its very simple structure. However, since the amount of particles and dust particles suspended in the inert gas 20 sent from the exhaust port will increase, it is difficult for the dust particle separator to completely intercept the particles and dust particles. Therefore, some particles and dust particles reach the steel furnace. Based on the above, there have been changes and improvements to the exhaust port and flue structure to prevent a large number of particles and dust particles from being introduced into the inert gas stream. The 6 inert gas stream rises into the coal coke drying and quenching equipment. It is discharged from the exhaust port and reaches the duct after passing through the flue. According to conventional techniques, an improved technology has been disclosed, which is related to a structure of an exhaust port and a flue, to prevent a large number of particles and dust particles from being introduced into the inert gas flow, which reaches the flue after passing through the flue. catheter. This know-how reveals: (1) an open end plane, facing the exhaust port inward, the exhaust port is inclined 60-80 relative to a horizontal line towards the center of the furnace. Angle; (2) the exhaust port is divided into an upper exhaust port and a lower exhaust port by a separator; (3) one wall of the lower exhaust port is inclined 45-80 ° relative to a horizontal line leading outward Angle; (4) the partition is set parallel to the wall of the lower exhaust port; and (5) the height of the inclined partition is set higher than the height of the coal coke pile at the exhaust port. The conventional technique also discloses another improved technique in which a plurality of through holes are formed on a refractory surface above an exhaust port at the entrance of the flue. The width of the through holes is smaller than the particle size of the coal char. According to this, the exhaust velocity in the exhaust port can be distributed slightly by separating the exhaust port into an upper exhaust port and a lower exhaust port with a separator. This can lead to a reduction in particles and dust particles introduced into the airflow. However, since the coal coke remains as it is even if the separator is fixed in the exhaust port—a coal coke pile defined by a stationary or stopping angle, the cooled inert gas intercepts particles and dust when flowing through the coal coke pile. Grains, go through this flue to reach _ Sheung Wan Road. Accordingly, further improvements are required to reduce the amount of particulates and dust particles introduced into the airflow. It can be reduced by flowing through the coal coke pile accumulated on the flue near the exhaust port.

The speed of the inert gas is cooled to reduce the amount of particles and dust particles introduced into the gas stream. This speed can be reduced by allowing the cooled inert gas to pass through a through hole in the upper surface of the exhaust port formed at the inlet of the flue. The width of the through holes is smaller than the particle size of the coal char. In practice, however, 5 hot coals are stacked to form coals piled at the entrance of a through hole in the coal coke drying and quenching equipment. This coal coke pile will have the function of ventilation resistance. Therefore, the main gas will still be discharged through the exhaust port instead of through the through holes. Moreover, these through holes may be blocked by particles and dust particles, which will reduce the ventilation function. 10 As mentioned above, although improvements have been made to the structure of the exhaust port and the flue to prevent the introduction of a large amount of particulates and dust particles into the inert gas flowing through the flue to the circle, further improvements are needed.

[Real cold type] Detailed description of the preferred embodiment Yi Xuan will detail the ^ Ming g Jihe tea research scheme in detail later. The same reference numbers are used to indicate the same or similar elements in many drawings. ίο 15 20 As shown in Fig. 1, the preparation chamber is formed by a ring-shaped inner wall. = The chimney 3 for exhausting the cooling inert gas is formed on the upper part of the main coke dry scale with the inner wall i and the coal coke dry wall 2 of the middle-order fire Dx prepared. The flue 3 is divided into several parts by the periphery of a number of cylindrical bricks 8 (see Fig. 2). The flue 3 is also connected to the US with its limbs above. A divider 4 is installed in the flue 3 to separate the flue 3 and the exhaust port 9 into upper and lower sections. In this example of the present invention, the partition 4 installed in the flue 3 is located and fixed on the longitudinal rib 5 of the partition, and its upper end is connected to the partition supporting member 7 and the partition supporting member # 7 is located on the ^ part of these left and right column monuments 8. In other words, the partition body 4, the partition body longitudinal ribs 5, and the partition support member 7 are suspended on adjacent left and right cylindrical bricks 8. The separator 4, the separator longitudinal ribs 5, and the separator support member 7 are preferably made of metal, for example, a heat-resistant steel alloy such as stainless steel, or a heat-resistant ceramic. The separator 4, the separator longitudinal rib 5 and the separator support member 7 can be connected to each other by welding or pins. However, it should be noted that the separator 4 may be connected in other ways. For example, the partition 4 can be directly connected at its left and right ends to adjacent left and right cylindrical bricks 8 for separating the flue 3 ^ The bottom edge of the partition 4 projects inwardly toward the coal coke drying quenching equipment The center of the wall extends beyond a plane (ab) of the open end of the exhaust port 9, that is, extends from the bottom edge (a) of the wall 1 constituting the preliminary chamber 5 to the wall 2a of the cooling chamber. The plane between the top edges (b). This configuration allows the bottom end of a ridge line of a coal coke pile to be positioned lower than the top edge of the wall constituting the cooling chamber. I need to know that the coal coke pile is stacked with a rest or stop angle formed in the area below the bottom edge of the partition 4 to form the ridgeline. The bottom edge of the partition 10 can extend until it reaches a plane 14. The plane 14 is an extension plane of one of the inner surfaces of the wall 1 constituting the preparation chamber. In addition, a ridge line 10a of the coal coke pile is also formed in a region below the bottom edge of the wall i that can form the preliminary chamber. Fig. 2 is a sectional view taken along line 11-11 of Fig. 1. As can be seen from the figure, the 15th-level exhaust ports 9 and the flues 3 are respectively formed with the partitions 4, which are located on the left and right sides of a central cylindrical brick 8, respectively. The spacer 4 is placed and fixed on the longitudinal rib 5 of the spacer. One upper end of the separator longitudinal rib 5 is connected to the separator support member 7. In addition, the partition support member 7 is placed on a circle on the left and right sides of the chimney 3; I; on the top of the main monument 8. In addition, in FIG. 20, each of the partitions 4 ′ is assembled in the exhaust ports 9 and the flues 3 on the left and right sides of the center cylindrical brick 8. Each of these partitions 4 is connected to each other by a round concrete brick region partition 6 which forms a side between adjacent exhaust ports 9. The round brick region partition is usually located at the same position as the side partition 4 protruding to the plane of the coal coke drying and quenching equipment beyond the 13 open end of the exhaust ports. The eight-cylinder brick area divider 6 can be made of the same material as the separator 4. The body 6 = connected to the round ridge area by _ or lock nails. The coal coke pile is defined by a continuous and smooth surface in the circumferential direction, defined by the angle of repose formed below the threshold. This can result in 2 substantially uniform gas flow at the exhaust port 9. Figure 3 is the exhaust port area of the separator 4 of the present invention, as viewed from the inside of the coal coke drying and quenching equipment, which corresponds to the embodiment of Figure 2. 6 This figure can be clearly understood 'A divider 4 includes a cylindrical brick region divider 6 that connects the divider 4 to two adjacent positions on the opposite sides of a middle central cylindrical tile 8... Figure 4 is a side cross-sectional view showing a convex body 丨6, which forms a surface substantially the same as the top surface of the partition body 4, and the convex body 16 can be fixed on the round brick 8 in FIG. 4 to replace the cylindrical brick area partition body 6 in FIG. 3. Open The convex body 16 formed on the cylindrical brick 8 has the same effect as the cylindrical brick area dividing body 6 of the third figure. The convex body 1 6 is formed by extending the cylindrical brick 8 or by applying a cast refractory material on the surface of the round brick 8 to form the round brick 8. The convex body 16 on the cylindrical brick 8 forms a surface adjacent to the adjacent one. Exhaust port 9 20. The upper surface of the convex body 16 and the upper surface of the circle obstructed area separator 6 as shown in Figs. 3 and 4, respectively, are substantially in the same plane as the separator 4 and Parallel. Although it is a beneficial configuration that the coal coke pile forms a continuous and smooth rest angle, it can also make the convex extension of the convex body 16 and the cylindrical brick area divider 6, 14 200418973 protrude to the divider 4 The parts of the coal coke drying and quenching equipment that exceed the plane of the open end of the adjacent exhaust port 9 are equal. A common extension surface is provided between the adjacent exhaust ports 9 to prevent coal coke particles from entering the lower part of the exhaust port. 5 FIG. 5 is an exemplary lateral cross-sectional view of the present invention, in which the partition 4 is assembled in the exhaust port 9 and the flue 3, and a convex π is fixed to the forming the preliminary cavity. The lower end of the wall 1 is located directly above the exhaust port 9.

Fig. 8 shows a gas velocity distribution near an exhaust port 9, in which a separator 4 is installed according to a conventional technique. When an exhaust port 9 is divided into an upper part and a lower part by a partition body 4, coal coke is stacked according to a rest angle surrounding a region from the exhaust port 9 to the inside of the flue 3 to form a stacking surface 1013. And 11 | 3. The thickness of the accumulated coal coke in the flue is smaller than the accumulated coal coke shown in FIG. 9, and it is formed without a separator 4. The gas velocity in the flue 3 near the exhaust port 9 is determined by the thickness of the coal char accumulated in the flue 3. When the exhaust port 15 is separated into an upper port and a lower port by the separator 4, the airflow in the flue 3 is divided into two airflows. This allows the speed distribution to be uniform to some extent, as indicated by reference numerals 12b and 13b. Since the maximum air velocity is smaller when a separator 4 is assembled (see Figure 9), the amount of particles and dust particles caused by the air flow can be reduced. However, since the upper and lower parts of the flue 3 20 formed by the separator still have coal coke piles near the exhaust port 9, the blowup and air velocity distribution will be improved less than expected. The present invention aims at the coal coke pile in the flue 3 near the exhaust port 9 and develops a method to reduce the amount of coal coke accumulated in the flue 3 near the exhaust port 9. Fig. 6 shows the results of the study by the inventors of the present invention. The missing of the above-mentioned conventional background 15 200418973 can be solved by the following structure, as shown in FIG. 6. In particular, forming the partition body 4 with a bottom edge protruding toward the center of the coal coke drying and quenching equipment beyond the open end of the exhaust port 9 can achieve the purpose of the present invention. The plane is defined as a plane extending between a bottom edge (a) of the wall 1 constituting the preliminary chamber and a top edge (b) of the wall 2a constituting the cooling chamber. By adopting

This structure can prevent coal coke from accumulating in the lower part of the flue 3 (such as the ridge line 11a). This can result in a substantially uniform air distribution 13a in the lower portion of the flue 3 near the exhaust port 9. The reason why the airflow distribution will be uniform is because there is no coal coke pile in the lower part of the flue 3, so the entire opening of the exhaust port 9 has no airflow resistance. Because the lower part of the flue 3 is near the exhaust port 9, the airflow resistance from the coal coke pile is eliminated, so the rising gas from the lower part of the coal coke drying quenching equipment is more likely to pass through the exhaust port than the upper part of the flue 3 Flows into the lower part of the flue 3. The reduced air flow in the upper part of the flue 3 can greatly reduce the amount of particles and dust particles caused by the airflow reaching the 15th ring. The reason why it can be greatly reduced is that the particles and dust particles are basically caused by the coal coke pile in the upper part of the flue 3, but not the lower part of the flue 3. Therefore, the reduction of the amount of airflow in the upper part of the flue 3 can greatly reduce the flow of particles and dust particles. Fig. 7 shows an embodiment of the present invention, in which a convex body 17 protruding toward the center of the preliminary chamber 20 is fixed to the lower end of the wall 1 forming the preliminary chamber. The convex body 17 is located directly above the exhaust port 9. In addition, the partition 4 extends to project into the interior of the coal coke drying and quenching equipment beyond the plane of the open end of the exhaust port 9. The plane extends from a bottom edge (a) of the wall 1 constituting the preliminary chamber to a top edge (b) of the wall 2a constituting the cooling chamber. The formation of the 16 convex body 17 can reduce the amount of coal char accumulated in the upper part of the flue 3 near the exhaust port 9 compared with the case where the convex body 17 is not formed. Fig. 9 shows the gas velocity distribution of the conventional coal coke drying and quenching equipment without separator 4 near the gas outlet 9 of the exhaust line. A coal coke pile defined by a repose angle forms a coal coke pile surface 18. This piled coal coke has the function of airflow resistance, which provides the airflow velocity distribution as shown by the dotted line in FIG. Fig. 8 shows the gas velocity distribution of the gas outlet 9 near a row, in which a conventional separator is installed. Since the exhaust port 9 is separated into an upper exhaust port and a lower exhaust port by the partition body 4, the amount of coal coke accumulated in the flue 3 is also separated. This separation of the amount of accumulated coal coke can lead to a reduction in airflow resistance in both the upper and lower exhaust ports. Assuming that the pressure difference of the airflow is fixed, the air flow rate with the separator 4 may be 1.4 times that without the separator 4. Assuming a fixed gas flow rate, the flow rate can be reduced by about 30%. This decrease in the flow speed can reduce the amount of particles and dust particles caused in the airflow, which can lead to a reduction in the amount of particles and dust particles that reach the bad track. As shown in FIG. 6, a partition 4 includes a bottom edge of the partition 4 protruding to a center of the coal coke drying and quenching equipment beyond a plane of the open end of the exhaust port 9, and the plane is extended to constitute the A plane defined between a bottom edge (a) of the wall 1 of the preparation chamber and a top edge (b) of the wall constituting the cooling chamber. By adopting this structure of the partition body 4, coal coke will not accumulate in the lower part of the flue 3 near the exhaust port 9. Therefore, compared to the upper flue, the airflow rate will increase due to no airflow resistance. However, the air flow velocity distribution 13a passing through the lower exhaust opening is substantially uniform. Thereby, the maximum flow velocity in the lower part of the flue 3 is smaller than that shown in FIG. 8 'which will result in reducing the amount of particles and dust particles caused in the airflow, and reducing the particles and dust reaching the ring channel. The amount of grain 200418973. As described above, increasing the amount of exhaust gas passing through the lower part of the flue 3 will decrease the amount of exhaust gas passing through the upper part of the flue 3. Therefore, compared with FIG. 8, the amount of particles and dust particles reaching the ring duct 15 in the upper part of the flue 3 in FIG. 6 will also decrease. This is because the amount of particles in the upper part of the flue 3 in FIG. 6 is reduced. Therefore, the airflow rate is small. This reduction occurs even when the amount of coal char accumulated in the flue 3 near the exhaust port 9 is the same in both Fig. 6 and Fig. 8.

As shown in Fig. 7, a convex body 17 is fixed to the lower end of the wall 1 which is fixed to form the preliminary cavity, and is located directly above the exhaust port 9. The convex body 17 protrudes toward the center of the preparation chamber. In addition to the partition body 4, the arrangement 4 of the convex body 17 reduces the amount of coal coke accumulated in the upper part of the flue 3 near the exhaust port 9. This reduces the peak value of the flow velocity distribution in the upper part of the side flue 3 near the exhaust port 9 'as shown in Fig. 12a. Therefore, the amount of particles and dust particles reaching the circle in the upper part of the flue 3 will also be reduced.

According to the present invention, the partition body 4 protrudes toward the plane of the coal coke drying and quenching equipment 15 beyond the open end of the exhaust port 9. The plane extends between a bottom edge (a) of the wall 1 constituting the preliminary chamber and a top edge (b) of the wall 2a constituting the cooling chamber. This prevents coal coke from accumulating in the lower part of the flue 3 near the exhaust port 9. According to this, it is possible to achieve an almost uniform air distribution in the lower part of the flue 3 near the exhaust port 9 and increase the amount of exhaust gas passing through the lower part of the flue 3. This can reduce the amount of particles and dust particles caused in the air stream. Increasing the amount of exhaust gas passing through the lower part of the channel 3 will decrease the amount of exhaust gas passing through the upper part of the channel 3, that is, reducing the air velocity. The amount of particles and dust particles in the channel is also lower. Because there is no coal char, the upper part of the flue 3 reaches the ring and the coarse particles can easily fall into the flue 3 18 200418973 exists in the lower part of the flue 3, so the coarse particles dropped It is lowered together with the coal coke in the coal coke drying and quenching equipment. Coarse particles that fall in will not reach the loop. The above is a detailed description of the present invention, and it is obvious that it can be changed in many ways. This change will not depart from the spirit and scope of the present invention, and all variations obvious to those skilled in the art are covered by the scope of the following patent applications. t BRIEF DESCRIPTION OF THE DRAWINGS 3 FIG. 1 is a side cross-sectional view of an exhaust port and a flue according to the present invention;
