The gas passage is formed to guide and discharge the COG gas generated during dry flow to the riser pipe smoothly to prevent undried shape near the door to improve the quality of coke and to prevent the leakage of gas through the door to prevent environmental pollution and workers. The present invention relates to a COG gas discharge passage forming device of a carbonization chamber that has been improved to improve the hygiene and health.

Generally, as shown in FIG. 1, a coke oven facility 100 includes a carbonization chamber 110 in which doors are installed at left and right sides, and coal is filled and filled in the carbonization chamber 110. An extruder 120 for extruding the coked coke, a transfer car 130 for transferring coke extruded to the outside by the extruder 120, and a charging hole 119 formed on an upper surface of the carbonization chamber 110. It is composed of a charging vehicle 140 for charging the coal through the inside, and the doors 111 and 112 are respectively provided on the left and right sides of the extruder 120 and the transfer car 130 and the carbonization chamber 110 corresponding to each other. .

The operation of manufacturing coke in the coke oven facility 100 is a high temperature for 17 to 18 hours by burning the fire from the bottom of the carbonization chamber 110 in the underjet system (UNDER JETSYSTEM) method and transmitting the radiant heat from both sides. Coal charged at (about 1260 ℃) is carbonized after producing high-strength coke.

In the process of charging and filling coal in the carbonization chamber 110 and then supplying a heat source in the carbonization chamber 110 to dry the carbon dioxide, the COG gas generated in the carbonization chamber 110 is discharged into the doors 111 and 112. ), It leaked to the outside and polluted the atmospheric environment, and the dry heat radiation for dry distillation was not made properly to the edge end side, which resulted in undried coke, which caused deterioration of the coke quality.

This is because when the coal is charged into the current carbonization chamber 110, the charged coal is gradually filled in the internal space of the carbonization chamber 110, so that a gas passage is formed only in the upper layer, and gas is collected at the upper layer side. COG gas generated from the will not be smoothly discharged above the carbonization chamber (110). Accordingly, even in the minute defects of the doors 111 and 112, the COG gas is leaked to the outside through the door equipment, and the flexibility near the doors 111 and 112 is caused by undesired flow due to the temperature drop. The coke quality deterioration phenomenon is occurring.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of which is to compress the coal charged in the carbonization chamber in the doors installed on both sides of the carbonization chamber to the center side, the COG gas generated during coal distillation is lower layer By forming a discharge passage that can be discharged smoothly from the upper part to the upper part, it prevents the outflow of COG gas to prevent pollution of the air environment and smoothly transmits radiant heat to the coal side which is charged to prevent dry coke at the edge of the carbonization chamber.

In addition, the mobile device 35 is equipped with a movement cylinder on which the compression cylinder 31 is mounted such that the rod end of the compression cylinder 31 and the contact plate 15b mounted at one end of the operation bar 15 come into contact with each other. The rotary cylinder 36 and the forward and backward cylinder 37 which bring 32 to the said door main body 14 side are comprised.

The operation of the present invention having the above configuration will be described.

First, extruding the coke co-cured in 18 to 20 hours in the carbonization chamber 110 to the outside of the whole amount, and for the next step of the door body 14 to seal the openings formed on the left and right sides of the carbonization chamber 110 The latch 16 operates to seal the internal space of the carbonization chamber 110.

When the door mounting work of the carbonization chamber 110 is completed, the extruder 120 and the transfer car 130 put into the extrusion work and the transfer work of the red coke are returned to the home position, and the compression part 30 is moved to the door part. There is no interference with the mobile device in close proximity to the door body 14 of (10).

When the home position movement of the extruder 120 and the transfer car 130 is completed, the forward and backward cylinders 37 of the mobile device 35 are first advanced, and the forward and backward cylinders 37 When the primary forwarding is completed, the rotary cylinder 36 is operated to rotate the mobile device 35, and then the forward and backward cylinders 37 are secondly advanced to operate the plurality of compression cylinders 31. The moving base 32 having is disposed close to the door body 12.

When the movement base 32 is disposed close to the outside of the door body 12 as described above, the rod end of the plurality of compression cylinder 31 installed in the movement base 32 and the door body 14 Since the contact plates 15b of the mounted operating bar 15 correspond to each other one-to-one, the operating bar 15 is also advanced to the carbonization chamber 110 side during the forward operation of the compression cylinder 31.

Accordingly, the casting plate 12 mounted at the tip of the operation bar 15 is locked to the door body 14 by the latch 16 so as to seal the opening of the carbonization chamber 110. (110) It is advanced to the inside, whereby the refractories 11 built on the front of the casting plate 12 is occupied and occupied in the space to be filled with coal in the carbonization chamber (110).

At this time, the moving plate 17 is caught on the locking step (15a) formed in the forward operation of the operation bar 15 is advanced to compress the tension spring (18a) mounted on the support bolt 18 to generate an elastic restoring force. .

As described above, in the state where the refractory of the casting plate 12 is occupied in the internal space of the carbonization chamber 110, the carbonization chamber 110 by using the charging vehicle 140 installed on the upper portion of the carbonization chamber 110. Coal is charged into the carbonization chamber 110 at a predetermined height, and the hydraulic pressure is continuously transferred to the compression cylinder 31 to maintain the state of advance. The refractories 11 are prevented from being pushed out by the weight and the pressure.

On the other hand, when the loading of coal using the charging car 140 is completed, the cast plate 12 is forward, forward and backward operation of the compression cylinder 31, the forward and backward operation of the compressed cylinder 31 is repeatedly inserted into The charged coal is compressed to prevent collapse.

Then, when the gas passage (P) is formed in the left and right inner space of the carbonization chamber 110 by the repeated forward and backward operation of the compression cylinder 31, when the compression cylinder 31 is slowly backward, the tension The operation bar 15 is returned backward by the elastic restoring force of the spring 18a, and the casting plate 12 connected thereto and the refractory 11 mounted on the front thereof are returned to the initial state.

In addition, when the casting plate 12 is returned to its original state, the moving cylinder 32 is returned to the home position by operating the rotary cylinder 36 and the forward / backward cylinder 37 as opposed to the above.

In this state, when a carbon source is supplied to the coal charged into the carbonization chamber 110 to carry out a dry distillation operation, the carbonization chamber may be formed between the loaded coal and the refractory 78 of the door body 14 by the refractory thickness. Since the gas passage (P) connecting from the lower portion to the upper portion of the 110 is formed, COG gas generated during the operation of carbonizing the coal charged in the carbonization chamber 110 is lowered through the gas passage (P). The discharge is induced smoothly from the side to the upper side. The COG gas discharged to the upper portion of the carbonization chamber 110 is collected and recycled through the gas collecting pipe 118 via the rising pipe 114.

Accordingly, the COG gas generated during the coal drying operation in the carbonization chamber 110 is prevented from leaking to the outside through the door body 14, and the carbonization in the carbonization chamber through the gas passage P is prevented. It is possible to prevent the undried phenomenon due to the mis-deterioration of the coal adjacent to the door body 14 side while the heat radiation flux is smoothly.

According to the present invention as described above, the lower layer and the upper layer of the carbonization chamber communicate with each other near the left and right door bodies of the carbonization chamber by the refractory material of the casting plate which is moved forward when charging the coal in the carbonization chamber and then returned backward at the time of charging completion. By forming a gas passage, coal is carbonized in the carbonization chamber, and the COG gas of the lower layer generated during the manufacturing process is smoothly discharged to the upper layer, and the radiant heat is circulated smoothly through the gas passage. By preventing leakage, it creates a pleasant and safe working environment, and facilitates the circulation of radiant heat to minimize the occurrence of dry matter of coke, which can produce high quality coke and significantly improve the coke working efficiency. Effect is obtained.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
