Description

Apparatus for removing foreign substances from the lin gas connection pipe of the coke oven {APPARATUS FOR REMOVING FOREIGN SUBSTANCE IN LEAN GAS CONNECTION PIPE OF COKE OVEN}

The present invention relates to a foreign material removal device for removing foreign substances generated inside a lean gas connection pipe of a coke oven and foreign substances accumulated in a shut-off coke.

Coke used as a heat source in a blast furnace is produced in a coke oven by carbonizing coal for a certain period of time and extruding and digesting the carbonized coal.

The dry distillation of the coal charged in the coke oven is performed using the combustion heat of the combustion chamber. Combustion chambers are installed on both sides of the carbonization chamber of the coke oven. In the combustion chamber, combustion gas composed of coke oven gas and furnace gas is supplied together with oxygen and combusted. The resulting exhaust gas is discharged to the outside through the exhaust valve. While exhaust gas is being discharged, supply and cut-off of combustion gas are repeated. In this way, the exchange process of restarting after shutting off the supply of combustion gas is called a reversing process. In order to perform the reversing process, a reversing cock for opening and closing the inner passage is installed. A shut-off cock and a lean gas distribution pipe are sequentially installed in a lower direction of the reversing cock, and a grease inlet is installed at a side of the reversing cock. A lin gas connection pipe is installed on the upper part of the reversing cock, and a cover is provided on the upper part of the rin gas connection pipe.

In this way, a rinsing gas connection pipe is formed in the coke oven, which is a space through which the rinsing gas can be transported. do.

The steam supply pipe 12 may be disposed on the front or part of the outer circumferential surface of the air suction pipe 12 . In FIG. 10, a structure surrounding the entire surface of the outer circumferential surface is illustrated.

A plurality of steam nozzles 20 are arranged at regular intervals on the tip (A) of the steam supply pipe 14 and the side (B) adjacent to the tip. The steam nozzle 20 serves to spray steam for dissolving foreign substances. The tip (A) means the lower surface facing the foreign material, and is located outside the open part of the air suction pipe (12).

A brush 30 is disposed between one steam nozzle 20 and the other adjacent steam nozzle 20 . The brush 30 serves to remove foreign substances dissolved by steam. The brush 30 rotates the body 10 in the left and right directions or moves it up and down to remove or remove the melted foreign substances from the inner surface of the rin gas connection pipe 100 .

Air intake and steam supply can be performed by means of a valve.

To this end, a steam valve 40 for controlling the amount of steam supplied is disposed at the rear end of the steam supply pipe 14 . When the steam valve 40 is opened, high-pressure steam from the steam nozzle 20 through the steam supply pipe 14 is sprayed into the rinsing gas connection pipe 100 to melt foreign substances.
