Description

[0001] Apparatus for closure of coke oven draft pipe [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a path opening / closing apparatus, and more particularly, to a path opening / closing apparatus capable of increasing sealing of a path formed by a riser of a coke oven, .

Generally, the coal stream in the steelmaking process is done in the coke process. The coke oven having the coke oven process has a plurality of carbonization chambers. The coke oven repeats the process of supplying coal to a plurality of carbonization chambers through the charge cargo and then carrying out the carbonization at a high temperature and extruding the carbonized product through the extruder.

In the process of carbonization of the coal, the volatile gas such as Cokes Oven Gas (COG) is sent to the Hwasung Plant through a rising pipe installed in the coke oven, and the gypsum coke discharged from the carbonization chamber is discharged through the coke oven It is transported to Coke Dry Quenching (CDQ).

On the other hand, in the carbonization chamber of the coke oven, waste coal and dust (DUST) are generated by burning and decomposing in the process of charging coal, and such waste gas and dust are passed through an ascending pipe for recovery.

At this time, a sealing device is provided at the upper part of the uprising pipe in order to suppress and prevent the outflow of waste gas and dust passing through the uprising pipe, thereby causing pollution of the atmospheric environment due to the waste gas and fractions present in the uprising pipe leaking to the outside It is solving.

However, the waste gas and dust passing through the riser pipe by the room temperature coal exhibit high temperature characteristics. As the high-temperature waste gas and dust continuously move through the riser pipe, the contraction and expansion of the dragon pipes constituting the riser pipe are repeated And damage to and detachment from the lead occurs. Accordingly, the up tube sealing device is subject to corrosion and banding due to the deterioration phenomenon due to the high temperature environment in the up tube, thereby causing the problem that the path sealing of the up tube is released.

In addition, when breakage occurs in the structure of the sealing device, it is necessary to replace and maintain the structure provided in the uprising pipe, but it is not easy to replace the components due to hot heat or waste gas discharged through the uprising pipe. Therefore, in order to replace the components, the operation of the coke oven is stopped, and the temperature of the components is lowered and then replaced, thereby increasing the time required for maintenance.

Therefore, the efficiency and productivity of the coke oven are deteriorated, resulting in an increase in manufacturing cost of the coke.

FIGS. 8A and 8B are views for explaining a state of sealing the up tube of the path switching device according to the embodiment of the present invention FIG.

Prior to the explanation of the path switching apparatus 1 according to the embodiment of the present invention, a coke oven facility in which coal is dried to produce coke oven will be described with reference to Fig.

The coke oven facility includes a coke oven 10 composed of a plurality of carbonizing chambers arranged side by side to form a space for carburizing coal as raw coal and a coke oven 10 installed at an upper part of the coke oven 10 for charging coal into the coke oven 10 And an extruder 30 installed at one side of the coke oven 10 for extruding the glow-plugged coke. A rising pipe 40 is connected to the inside of the coke oven 10 to form a path for discharging the gas generated during the carbonizing of the coal and a bending portion 50 is formed on the upper side of the rising pipe 40 , The gas exhausted to the uprising pipe 40 moves to the bending portion 50 and is collected in the gas collecting pipe 52. The collected gases are then transferred to a subsequent treatment facility or a gas treatment facility via a subsequent exhaust line 54 connected to a gas collection tube 52 to move to a subsequent treatment facility. The path opening / closing apparatus 1 according to the embodiment of the present invention, that is, the ascending / descending opening / closing apparatus, is configured to prevent the high temperature waste gas and the dust generated from coal from being scattered to the atmosphere through the ascending pipe The sealability of the path of the pipe can be improved. Also, the path opening / closing apparatus 1 according to the embodiment of the present invention can suppress and prevent deterioration of the component due to the temperature of the waste gas and the dust that flow into the uprising pipe 40. [ Hereinafter, an example in which the path opening / closing apparatus 1 is disposed above the uprising pipe 40 will be described.

The driving unit 120 is connected to the upper portion of the cover unit 110 and can lift and lower the cover unit 110 from the sealing unit 130.

That is, the path opening / closing apparatus 1 opens and closes the uprising pipe 40 by seating the cover portion 110 on the sealing portion 130, so that the sealing member 130 (for example, a water seal) It is possible to prevent the sealing member W in the receiving groove 134 from swinging to a large extent by providing the partition wall 135 having the double partition wall structure in the receiving groove 134, The foreign matter can be easily deposited on the bottom of the receiving groove 134. [ Thus, it is possible to suppress or prevent the sealability between the cover portion 110 and the sealing portion 130 from being released or the sealing property from being reduced due to the impurity of the sealing member W. This will be described in detail below.

The sealing part 130 is disposed at a lower portion of the cover part 110 and can seat the cover part 110. The sealing part 130 is formed at least partly in the up- An inner wall 133 which is disposed in contact with the inner surface of the outer shell 131 and forms a receiving groove 134 and a receiving groove 134 which is formed in the receiving groove 134, And a partition wall 135 for horizontally dividing the accommodating space r of the sealing member W to be formed. The sealing part 130 is provided with a first sealing member 137 for covering the contact area between the outer shell 131 and the inner wall 133 and a sealing member feeder for supplying the sealing member W to the receiving groove 134. [ (Not shown) for collecting the sealing member W in the receiving groove 134 (not shown).

The outer shell 131 has at least a part of the outer surface 131a and the inner surface 131b which are arranged in close proximity to the inner wall of the up tube 40 extending in the vertical direction, And a predetermined length is formed. At this time, at least a part of the outer surface 131a of the shell 131 may be inserted into the inner surface of the uprising pipe 40. The outer shell 131 may be fixed to the inner surface of the uprising pipe 40 by a separate fixing member such as an adhesive member on the inner surface of the uprising pipe 40, And may have an average outer diameter that can be inserted in contact with the side surface and may be fixed only by inserting into the up tube 40.

The inner wall 133 surrounds the inner surface 131b of the outer envelope 131 and is disposed in contact with the outer envelope 131 to form a receiving recess 134 between the outer surface 131 and the inner surface 131b of the envelope 131. [ do. The inner wall 133 is disposed in contact with the inner circumferential surface 131b of the outer envelope 131 and in contact with the inner circumferential surface 131b of the outer envelope 131, The receiving grooves 134 can be formed between the inner walls 133. [ 4, the inner wall 133 is brought into contact with the inner surface 131b of the outer shell 131 up to a predetermined position in the vertical direction from the lower portion to the upper portion of the inner surface 131b of the outer shell 131 A plane is formed in the direction of the inner side of the uprising pipe 40 and then extended to the top so that the inner surface of the inner wall 133 facing the outer surface 131 and the inner surface 131b The receiving groove 134 may be formed.

The first sealing member 137 covers an area in contact between the outer shell 131 and the inner wall 133 so that the gap between the outer shell 131 and the inner wall 133 when the sealing member W is received in the receiving groove 134 To prevent or prevent the sealing member W from being seized onto the contact portion of the sealing member W. That is, the first sealing member 137 is formed in a shape corresponding to the cross-sectional shape of the receiving groove 134, the lower surface is in contact with the lateral surface of the inner wall 133, And the other surface may be disposed in the receiving groove 134 in contact with the inner surface of the inner wall 133. [

The partition wall 135 may be provided in the receiving groove 134 or may be provided on the inner bottom surface of the first sealing member 137 when the first sealing member 137 is provided, The partition wall 135 has a first partition 135a for first dividing the accommodation space r formed by the receiving recess 134 in the horizontal direction, And a second partition 135b which is disposed apart from the first partition 135a in the outward direction and secondarily divides the first accommodating space r1, r2 in the horizontal direction. That is, the partition wall 135 is formed in the accommodating space r by a total of three spaces by the first partition 135a and the second partition 135b which horizontally divide the accommodation space r of the accommodation groove 134. [ Can be divided.

The first partition 135a is disposed in the receiving groove 134 to divide the receiving space r into the first space r1 and the second space r2 and the total height of the receiving groove 134 in the up- And may be formed to extend from the inner bottom of the formation receiving groove 134 to a predetermined height at a lower height. The first partition wall 135a may be disposed to be offset toward the inner side of the uprising pipe 40 from the center position with respect to the center position of the total width in the horizontal direction of the receiving recess 134. [ That is, the second space r2 may be arranged to have a relatively larger space than the first space r1, and the width of the first space r1 in the horizontal direction may be set such that the sealing member W can accommodate a certain amount And may be disposed at a position having an area where some of the cover parts 110 described later can be loaded. The first barrier rib 135a may be formed in such a manner that the sealing member W accommodated in the accommodation space r is connected to the riser pipe 40 when the cover member 110 covers the sealing portion 130. [ The gas is discharged partially out of the space and discharged through the space between the cover part 110 and the sealing part 130 so that the gas is discharged toward the accommodation space r so that the sealing member W swings largely, It is possible to solve the problem of lowering of the sealability that may occur due to the exposed state of the sealing member W in the cover member 110, rather than the state in which some of the cover member 110 is immersed. That is, the sealing member W, which largely swings in the receiving groove 134 due to the external environment, hits the first partition wall 135a and partially loses the oscillating property of the sealing member W. In the first space r1, It is possible to restrain the member W from coming off, and it is possible to suppress or prevent the occurrence of a decrease in the sealability due to a part of the constitution of the cover portion 110 becoming an exposed state.

The second partition 135b is spaced apart from the first partition 135a in the receiving groove 134 so that the first partition r1 and the second space r2 R2-1 and r2-1 formed between the first barrier rib 135a and the second barrier rib 135b and the second barrier rib 135b formed between the first barrier rib 135a and the second barrier rib 135b, And a falling space r2-2 formed between the first electrode 131 and the second electrode 131 can be formed. That is, the second partition 135b is biased toward the first partition 135a from the center on the basis of the total width in the horizontal direction of the second space r2, so that the fall space r2 -2) may have an increased area. The sealing member W can be received in the rising space r2-1 in a smaller amount than the first space r1 and the sealing member W can be received in the falling space r2 -2). ≪ / RTI > The falling space r2-2 provides a space in which the sealing member W falling from the rising space r2-1 falls and is accommodated. At this time, the second barrier ribs 135b may be disposed higher than the first barrier ribs 135a, and the upper ends of the second barrier ribs 135b may be disposed higher than the upper ends of the first barrier ribs 135a. On the other hand, at least one discharge hole 135b-1, which is formed in the second bank 135b through the second bank 135b in the horizontal direction and has a lower end positioned higher than the upper end of the first bank 135a, .

The discharge hole 135b-1 may be formed by laterally penetrating the second partition 135b at a position spaced downward from the upper portion of the second partition 135b, as shown in Fig. 4 (a) . 4B, the lower end of the discharge hole 135b-1 is located at a position higher than the upper end of the first partition 135a, so that the discharge hole 135b-1 extends beyond the first partition 135a, -1, the seal member W supplied to the position higher than the lower end of the seal member W can be discharged to the fall space r2-2. At this time, the discharging hole 135b-1 may be provided with a collecting member 135b-2 including a mesh-like net forming a plurality of meshes.

The collecting member 135b-2 filters a part of the foreign substances in the sealing member W which is mounted on the discharge hole 135b-1 and moves to the dropping space r2-2 through the discharge hole 135b-1. And the collecting member 135b-2 may be formed in the form of a net that forms a plurality of meshes. At this time, the collecting member 135b-2 can form a dense mesh that can filter foreign substances that may be contained in the sealing member W. [

In this case, one discharge hole 135b-1 is formed in the second partition 135b along the periphery of the second partition 135b, and one collecting member 135b-2 is provided so as to correspond to the discharge hole 135b- -1, but the number of the discharge holes 135b-1 and the collecting member 135b-2 is not limited, and may be formed in various numbers and shapes.

The second partition 135b divides the second space r2 into the rising space r2-1 and the dropping space r2-2 so that the oscillating property of the sealing member W passed through the first partition wall 135a The first partition 135a serves to cancel foreign substances in the sealing member W that may be included in the sealing member W. [

On the other hand, in the first space r1 and the second space r2 in which the partition wall 135 of the sealing portion 130 is divided, a sealing member 134 for supplying and recovering the sealing member W into the receiving recess 134, A feeder (not shown) and a sealing member collector (not shown) may be connected. That is, the sealing member feeder may be connected to at least one of the first space r1 and the second space r2, and more preferably, it may be connected only to the first space r1. The sealing member feeder supplies the sealing member W to the first space r1 by a predetermined amount and supplies the sealing member W to the first space r1 in accordance with the progress of the process, The sealing member W in the sealing member W may be provided with a sealing member W containing no foreign substance. The sealing member collector (not shown) may be connected to the second space r2, and more preferably, the rising space r2-1 and the falling space r2-2, which are divided in the second space r2, It is possible to recover the sealing member W existing in the falling space r2-2 by being connected to the falling space r2-2. This is because the sealing member W falling down into the falling space r2-2 through the rising space r2-1 due to the characteristics of the multi-stage partition wall formed by the partition wall 135 has a state in which the foreign matter is partially separated, it is possible to collect the sealing member W having a relatively smaller amount of foreign matter than when the sealing member W is connected to the sealing member recovery unit r2-1 by connecting the sealing member recovery unit.

The cover 110 is positioned on the upper side of the sealing part 130 and can be seated on the upper surface of the sealing part 130 or separated from the upper surface of the sealing part 130 according to the operation state of the driving part 120 described later. The cover 110 has a protruding member (hereinafter, referred to as a protruding member) formed in a space in which a cooling medium is received (hereinafter referred to as a cooling medium accommodating space C · A) And a blocking member 114 disposed at a position spaced apart from the bottom of the cover 111 in the inward direction of the protruding member 112 and detachable from the lower portion of the cover 111 The cover portion 110 is provided so that at least a part of the lower portion is inserted into the sealing portion 130 so that the path 45 of the uprising pipe 40 can be closed.

That is, when the cover 111 is composed only of the body 111a and the lid 111b, the cooling medium accommodating space C · A may be a space from the inner bottom surface of the body 111a to the lid. At this time, the body 111a and the lead 111b can be prevented from being separated from each other through a separate fixing member.

The protruding member 112 is disposed at the lower portion of the cover 111 and is inserted into the first space r1 of the receiving groove 134 to be immersed in the sealing member W accommodated in the first space r1, And the cover portion 110. [0031] That is, the protruding member 112 has a predetermined length in the up-and-down direction and is provided with a ring with upper and lower openings. The lower end of the protruding member 112 is inserted into the first space r1 and is inserted between the first partition 135a and the inner wall 133 . At this time, the average diameter in the horizontal direction of the projecting members 112 is smaller than the average diameter in the horizontal direction of the first bank 135a, so that at the position spaced inward from the first bank 135a, (134). The height of the protruding member 112 in the up-and-down direction may be formed to be smaller than the depth of the receiving groove 134 and inserted into the receiving groove 134.

The blocking member 114 is detachably attached to the lower portion of the cover 111 or the lower surface of the body 111a so that the blocking member 114 is inserted into the center of the inner wall 133 to contact the sealing portion 130 and the cover portion 110 And may be provided to increase the sealing property by increasing the area.
