Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coke oven door,

The present invention relates to refractory cleaning / coating apparatus for coke oven doors.

1 is a schematic view showing a coke oven. Referring to FIG. 1, generally, a coke oven 10 having a plurality of carbonizing chambers is charged with coal into a carbonization chamber using a charge car, For about 26 hours by shutting off and heating the outside air.

Such an operation is called a " cargo operation ", and the coke that has undergone the carbonization operation is discharged to the outside of the carbonization chamber 40 through the extrusion operation. The coke oven door 20 is pulled out by using the door lifter 70 to open the carbonization chamber 40 and then extruded into the transfer car using the ram 60 of the extruder 50. [

Foreign matter such as tar and carbon generated during the coke oven door drying process is adhered to the side surface of the coke oven door 20. When the coke oven door 20 is fastened to the carburizing chamber 40 without removing the foreign substances, 40 and the coke oven door 20, as shown in Fig.

When a gap is formed between the coke oven door 20 and the carbonization chamber 40, the coke oven gas generated during the coke oven gas leaks to the outside along with the gap to threaten environmental pollution and safety of workers, And the incomplete combustion occurs in the carbonization operation to cause a problem in that the quality of the coke is deteriorated.

Therefore, in order to solve the above-mentioned problems, various methods have been developed. Among them, generally used technology is a technique of cleaning the coke oven door using high-pressure water.

The technology using this washing water can remove tar and carbon adhering to the surfaces of the coke oven door and the door frame by spraying the washing water supplied from the outside with a certain pressure. On the other hand, The spraying nozzle is clogged or damaged (abraded), thereby limiting the spraying range, and the working efficiency is lowered.

Particularly, it is not possible to effectively remove tar and carbon due to clogging or damage of the spray nozzle, which causes poisonous gas to leak to the outside through gaps in the coke oven door, thereby causing environmental pollution as well as safety accidents .

In this case, when the tar and carbon adhering to the surfaces of the coke oven door and the door frame can not be removed, the operation is required to be performed for maintenance or removal work, resulting in a problem of delay in production.

In addition, since separate operators are required to remove tar and carbon, the waste of labor costs is unnecessarily wasted, thereby providing a cause of safety accidents.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

First, before describing the coke oven door refractory cleaning / coating apparatus according to an embodiment of the present invention, a brief description will be given of the principle of carbon adhering to the refractory of the coke oven door.

The volatile matter generated during coal combustion is a large amount of gaseous components and tar. In the course of the conversion of the double volatile matter to the gaseous phase, the fixed carbon component receives high heat and decomposes and dissociates. At this time, the coke is adhered to the coke oven door, and the carbon is adhered to the refractory.

Then, as the carbonization time of the coke progresses, the amount of volatile matter increases. When the temperature reaches about 700 ° C, the generation rate decreases by 1% when the water content of the charging coal decreases and the volatile content of the charging coal decreases by 1% The rate at which carbon is deposited on the refractory is increased at a rate of about 6 to 7%. The reason of this mechanism is that the tar or pitch carbon component undergoes carburizing and carburizing phenomenon, which is then attached to the refractory of the coke oven door.
