Abstract

PROBLEM TO BE SOLVED: To provide a method of operating a coke oven which can operate the coke oven without deteriorating coal charging efficiency even when one of two coal charging cars has broken down.SOLUTION: When coke is produced by charging coal into a carbonization chamber of the coke oven 21 from a coal charging car 16 which travels on the oven top part of the coke oven 21, a reserve coal charging car 20 is arranged near the oven end of the coke oven 21 and the coke oven 21 is operated by replacing the broken coal charging car 16 with the reserve coal charging car 20.

Description

  The present invention relates to a coke oven, and more particularly, to a method for operating a coke oven in which a large number of carbonization chambers and combustion chambers are alternately formed in an upper portion of a heat storage chamber.

  As shown in FIG. 3, the chamber furnace type coke oven has a structure in which a large number of carbonization chambers 12 and combustion chambers 13 are alternately formed in the upper part of the heat storage chamber 11. The coal stored in (1) is charged from a coal-coating vehicle 16 traveling on a track 15 arranged on the top of the coke oven. The coal charged into the carbonization chamber 12 from the coal loading vehicle 16 is subjected to dry distillation by the heat generated in the combustion chamber 13 to become coke, and then extruded from the carbonization chamber 12 by the extruder 17. The coke extruded from the carbonization chamber 12 is supplied to a fire extinguisher 19 from a guide wheel 18 disposed on the opposite side of the extruder 17 and extinguished by the fire extinguisher 19.

  By the way, when coke is produced | generated by charging coal in the carbonization chamber of such a coke oven, the operation of the coke oven is normally performed using two coal-equipped vehicles. And when one of the two loaded cars fails during operation, the failed loaded car is moved to the furnace end of the coke oven as suggested in Patent Document 1 or Patent Document 2. After that, coal is charged into the coking oven's carbonization chamber using the one that has not failed.

According to the above-described method, it is possible to repair a broken coal-mounted vehicle without stopping the operation of the coke oven. However, until the repair of the broken coal-bearing vehicle is completed, there is a problem that the coal charging efficiency is greatly reduced because the coal must be charged by only one coal-mounted vehicle.
The present invention has been made in view of the above-described problems, and the object thereof is to provide a coke oven without greatly reducing the charging efficiency of coal even if one of the two loaded cars fails. It is to provide a method for operating a coke oven that can be operated.

  In order to solve the above-mentioned problems, the method of operating a coke oven according to the present invention, when charging coal into a carbonization chamber of a coke oven from a coal-carrying vehicle that runs on the top of the coke oven to generate coke, Preliminary charcoal vehicle is disposed near the end of the coke oven, and the coke oven is operated by replacing the charcoal vehicle with the preliminary charcoal vehicle when the charcoal vehicle breaks down. Mounted on a fixed deck provided in the vicinity of the furnace end of the coke oven, and a two-stage movable upper and lower stage provided between the fixed deck and the furnace end of the coke oven is installed on the carbonized car to be exchanged with the pre-charged car. After moving the upper deck portion or the lower deck portion of the deck, the movable deck is moved upward or downward to a predetermined position, and the preliminary coal-car is moved from the fixed deck to the lower deck of the movable deck. Or characterized in that the replacement of the instrumentation Tansha is moved on the upper deck section is performed.

  According to the present invention, it is possible to charge coal into the carbonization chamber of the coke oven with two units of a non-faulted loaded vehicle and a preliminary loaded vehicle. Therefore, one of the two loaded vehicles is loaded with coal. Even if there is a failure, the coke oven can be operated without greatly reducing the charging efficiency of coal.

It is a figure which shows the operating method of the coke oven which concerns on the 1st Embodiment of this invention. It is a figure which shows the operating method of the coke oven which concerns on the 2nd Embodiment of this invention. It is a figure which shows schematic structure of a coke oven.

Hereinafter, a method for operating a coke oven according to the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 is a diagram illustrating a coke oven operating method according to the first embodiment of the present invention. In the figure, reference numeral 20 denotes a pre-charged coal car, and this pre-charged car 20 is mounted on a fixed deck 22 provided near the furnace end of a coke oven 21.
The fixed deck 22 is provided in the vicinity of the furnace end of the coke oven 21 at substantially the same horizontal level as the top of the coke oven 21 where the coal loaded vehicle 16 travels, and between the fixed deck 22 and the furnace end of the coke oven 21. The upper and lower movable decks 23 are provided so as to be movable up and down.

  When replacing the failed coal loading vehicle 16 with the spare coal loading vehicle 20 using the fixed deck 22 and the movable deck 23, first, as shown in FIG. Move on the lower deck 23a. Next, as shown in FIG. 1C, the movable deck 23 is driven downward by a movable deck driving device (not shown) until the upper deck portion 23b of the movable deck 23 is at the same horizontal level as the fixed deck 22. When the upper deck portion 23b of the deck 23 reaches the same horizontal level as the fixed deck 22, the lowering operation of the movable deck 23 is stopped. Then, as shown in FIG. 1 (d), the preliminary coal loading vehicle 20 mounted on the fixed deck 22 is moved onto the upper deck portion 23 b of the movable deck 23 and further moved onto the upper deck portion 23 b of the movable deck 23. The prepared pre-coating vehicle 20 is moved onto the top of the coke oven 21.

  As in the first embodiment described above, when the coke is generated by charging coal into the coking chamber of the coke oven 21 from the coal loading vehicle 16, the preliminary coal loading vehicle 20 is disposed in the vicinity of the furnace end of the coke oven 21. In addition, when the coal-coating vehicle 16 that has failed at the time of the failure of the coal-coating vehicle 16 is replaced with the pre-coating vehicle 20, the coal is charged into the coking chamber of the coke oven 21 with two units of the non-failing coal-coating vehicle and the pre-coating vehicle 20. Is possible. Therefore, even if one of the two loaded cars 16 breaks down, the coke oven 21 can be operated without lowering the charging efficiency of the coal.

  In the above-described first embodiment, the failed coal loaded vehicle 16 is moved onto the lower deck portion 23a of the movable deck 23 and replaced with the spare coal loaded vehicle 20, but the second embodiment of the present invention shown in FIG. The movable deck 23 is moved until the lower deck portion 23a of the movable deck 23 reaches the same horizontal level as that of the fixed deck 22 after the failed coal loaded vehicle 16 is moved onto the upper deck portion 23b of the movable deck 23 as in the embodiment. Is driven upward by a movable deck driving device (not shown), and the pre-loaded coal vehicle 20 is moved from the fixed deck 22 to the lower deck portion 23a of the movable deck 23, so that the broken coal-coating vehicle 16 is You may make it replace.
