The present invention prevents air pollution and corrosion of facilities by preventing the gas generated during the coking process in a carbonization chamber from leaking out in multiple stages, and smoothly supplying coke to the post-process and reducing the formation of upper carbon in the carbonization chamber. The present invention relates to a gas sealing apparatus of a carbonization chamber, which prevents the opening passage from being closed and reduces the extrusion resistance during the extrusion operation of the red coke.

In general, as shown in FIG. 1, the coke manufacturing equipment charges coking coal into a carbonized chamber 110, which is a closed coke oven, as a charging vehicle 120, and cuts off air. 1300 ° C.) to produce coke, an off-white solid compound.

The coal charged into the carbonization chamber 110 in the coke manufacturing facility is dried to lower the coal content of 9% water content of about 9% by using a large dryer to the fuel chamber 110 to reduce the fuel cost, and then into the carbonization chamber 110 34 tons of coal will be charged per charge. In FIG. 1, reference numeral 111 is a refractory brick constituting the upper portion of the carbonization chamber, 140 is an extruder.

Coal charged in a low moisture state as described above to generate a large amount of COG gas instantaneously in the dry distillation process to increase the internal pressure of the carbonization chamber 110, at this time, to prevent the generated gas is discharged to the outside, 2 and 3, the sealing device 180 is provided to seal the door 150 of the carbonization chamber 110.                         

The sealing device 180 includes a bracket 189 fastened to the door 150 as a screw member 182, a position adjusting screw 181 for adjusting the up and down position of the bracket 189, and the door 150. A tension strip 187 for elastically supporting the sealing strip 185 contacting the front and end of the door frame 190 disposed in front and the pressure port 186 contacting the other end of the sealing strip 185 is accommodated. A casing 184 and a tension adjusting screw 183 for adjusting the tension of the tension spring 187.

The door frame 190 is inserted into a buck stay, which is a beam supporting the carbonization chamber, but is sealed between the beam and the door frame due to high temperature carbonization temperature (1200 ° C.) and irregular contraction and expansion. Is damaged, and tar, carbon, etc., generated during coal distillation in the carbonization chamber are leaked and fixed, thereby causing air pollution such as damage to facilities, and tightening the tension adjusting screw 183 of the sealing device 180 to generate a gap. Minimized.

However, the generation of a gap (Gap) due to the heat deformation of the door frame 190, the C.O.G gas is leaked to the outside to promote environmental pollution and equipment corrosion, while adversely affecting the human body when the worker inhales.

In addition, when the sealing device 180 of the door 150 causes bending due to a heat source, gas generated inside the carbonization chamber 110 when the coke drying is completed by a gap generated at this time. In this case, the internal pressure of the carbonization chamber 110 is lower than atmospheric pressure.

In this case, cold air flows into the carbonization chamber 110 to rapidly cool the temperature of the carbonization chamber, and thus, between the silica refractory brick 112 constituting the inner wall of the carbonization chamber 110 and the refractory brick 112. As a result of the dropping of the sealing portion of the carbonization chamber 110, the gas generated in the combustion chamber 110 penetrates into an adjacent combustion chamber (not shown), thereby causing a variation in the combustion ratio in the combustion chamber, thereby becoming a major cause of air pollution.

In addition, since the upper temperature in the carbonization chamber 110 becomes high, the carbon formed by the formation of active carbon forms a thick layer at the top, thereby minimizing the gas passage, thereby causing a secondary problem of obstructing the flow of generated gas. Overheated coke extrusion was a major cause of increasing the extrusion resistance, there was a problem of prolonging the work delay and equipment down time.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of which is to prevent external pollution of the gas generated during the coking process in the carbonization chamber to prevent air pollution and corrosion of equipment, It is to provide a gas sealing apparatus of a carbonization chamber that can smoothly supply coke to the post-process and reduce the formation of the upper carbon in the carbonization chamber to prevent the opening passage from being closed, and reduce the extrusion resistance during the extrusion operation of the red coke.

As a technical configuration for achieving the above object, the present invention,
