Description

{Cleaner for cleaning door of coke oven}

The present invention relates to a coke oven door cleaner. More particularly, the present invention relates to a coke oven door cleaner capable of effectively removing foreign matter adhering to the surface of a coke oven door.

Generally, the coke oven facility has a plurality of carbonization chambers for charging coal, and a heat coke is produced in the carbonization chamber by applying 1,250 ° C. heat for about 18 hours.

In this coke making process, fuel is supplied to the inside of the carbonization chamber through the inlet of the upper portion of the carbonization chamber, and the gaseous coke that has been completely dried is loaded into the fire extinguishing vehicle through the region where the coke oven door is opened. .

Such a coke oven facility is provided with a door for the inflow of coal and the discharge of coke, and each door is operated by a desorption device to open or close the carbonization chamber.

Gases generated in the process of gypsum coke combustion in the carbonization chamber of the coke oven are not leaked out to the outside by the coke oven door.

1 and 2, in the coke oven facility 2 of the coke oven plant, coal is charged into the carbonization chamber 11 of the coke oven 10 by using the charging car 3, It is a facility to perform the coking process.

In the coking process, a coke oven gas is generated in the coke oven 10 according to the coking of the coal. The gas is sent to the chemical conversion process through the uprising pipe 13 and the gas collecting pipe 14 through the gasway 12 of the carbonization chamber 11.

3, the gas stagnant in the carbonization chamber 11 causes a large amount of foreign matter (e.g., nitrogen oxides) to flow through the surface of the coke oven door 20 or the sealing strip 21 and the door frame 30 of the coke oven door 20. [ (M, tar, carbon, etc.) are adhered.

However, when the foreign matter is not removed, there is a problem that gas leakage occurs due to a poor sealing of the coke oven door 20, as shown in FIG.

Furthermore, there is a problem that the risk of industrial accidents increases due to a flame or a high temperature gas when a gas leakage occurs due to the failure to remove the adhered foreign matter.

That is, a large amount of foreign matter (M, tar, carbon, etc.) generated in the process of producing the coke is prevented from entering into the surface of the sealing strip 21 of the coke oven door 20 or the coke oven door 20, And the airtightness of the coke oven 10 by the coke oven door 20 is impaired by the foreign matter M adhered thereto.

As a result, the high-temperature gas flows out of the coke oven, damaging and deforming various facilities, and threatening the safety of workers.

Such a coke oven door cleaner can be installed in the extruder 4 or the transfer car 5, as shown in Fig.

However, when the cork oven door cleaner is used to move the cork oven door cleaner effectively to remove the foreign matter M adhering to the cork oven door 20 or the like, the nozzle strikes the adhered foreign matter M, (Refer to FIG. 5A) or to be removed (refer to FIG. 5B).

In addition, there is a problem that the foreign matter M adhering to the coke oven door 20 or the like can not be removed due to the deformation (ejection direction deformation) of the nozzle 40 and the like. Accordingly, maintenance work also increases.

Further, when the high-pressure water is injected through the nozzle to remove the foreign matter, there is a problem that the pipe or the nozzle to which the high-pressure water is conveyed is clogged in freezing weather or frozen.

On the other hand, there is a coke oven door cleaner of Korean Patent No. 10-0907311 (2009.07.03) of the applicant of the present invention as an invention relating to the removal of the foreign matter (M).
