Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a coke oven carbonization chamber carbon removal device.

[Prior Art] In a coke carbonization chamber, adhered carbon is generated by thermal decomposition of carbonized gas and by pulverized coal scattered during coal charging that adheres to the furnace wall of the coke carbonization chamber and turns into coke. This deposited carbon grows on the furnace wall surface, lowering the thermal conductivity of the furnace wall, reducing the effective volume of the carbonization chamber, and lowering productivity. Furthermore, it causes so-called kiln clogging, which makes it impossible to extrude coke. However, it is necessary to remove this carbon.

As a conventional coke oven carbonization chamber carbon removal device, there is one disclosed in JP-A-63-14033. As shown in FIG. 2, this device includes a carbonization chamber 20 having a furnace lid 21, a charging port 22, and a gas riser pipe 23, a charging car 24 placed on the top surface of the carbonization chamber 20, and a charging car 24 placed on the top surface of the carbonization chamber 20. A blower 25 placed on the top of the car 24 and a blower 25
and an injection nozzle 27 which is connected through a flexible tube 26 and inserted into the carbonization chamber 20. In such a device, air from the injection nozzle 27,
By supplying a gas such as oxygen into the carbonization chamber 20, the inside of the carbonization chamber 20 is forcibly stirred, and the carbon adhering inside the carbonization chamber 20 is burned. Combustion gas generated by combustion is exhausted to the outside world from the gas riser pipe 23.

[Problems to be Solved by the Invention] However, since the above-mentioned device naturally exhausts the generated combustion gas to the outside world, the gas blown into the carbonization chamber tends to have a biased flow in the carbonization chamber, and the deposited carbon is Poor combustion removal efficiency. In addition, in the above device, since the gas riser pipe 23 is open to the outside world, dust may be transferred to the gas riser pipe 23 during operation.
There is a fear that it will be released into the outside world from 3. Furthermore, the above-mentioned device is a device exclusively for removing carbon from the coke oven carbonization chamber.

The present invention has been made in view of the above points, and is a coke oven carbonization chamber carbon removal method that can efficiently remove carbon attached to the carbonization chamber using existing equipment without emitting dust to the outside world. The purpose is to provide equipment.

[Means for Solving the Problems] The present invention provides a carbonization chamber having a charging port and a gas riser pipe;
A coal loading car is detachably mounted on the carbonization chamber, a gas blowing means is attached to the coal loading car so as to blow gas from the charging port, and An exhaust passage provided in the coal loading car so as to communicate with the charging port for exhausting generated combustion gas and collecting dust, and a suction means for exhausting the combustion gas and collecting dust. This is a coke oven carbonization chamber carbon removal device characterized by:

[Operation] The coke oven carbonization chamber carbon removal device of the present invention utilizes a coal loading car, which is an existing facility. The coal loading car is equipped with a dust collection duct, a dust collector, a blower 1, and a nozzle.

Therefore, the dust collection duct can be used as a combustion gas exhaust passage, and the dust collector can be used as a combustion gas suction means.

As a result, the gas blown into the carbonization chamber through the nozzle by the blower of the furnace top cleaner burns the carbon deposited inside the carbonization chamber while stirring the inside of the carbonization chamber. The combustion gas generated by this combustion is actively exhausted through the exhaust passage by the suction means.

The suction means also collects dust entrained during operation.

As a result, carbon adhering within the carbonization chamber can be efficiently removed.

[Embodiments] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a schematic diagram showing a coke oven carbonization chamber carbon removal device of the present invention. In the figure, 1 is a carbonization chamber. Carbonization chamber 1
A furnace lid 2 is attached to the side surface of the furnace. A plurality of charging ports 4 are provided on the upper surface of the carbonization chamber 1. Furthermore, a gas riser pipe 3 is attached to the upper surface of the carbonization chamber 1 .

On the upper surface of the carbonization chamber 1 in a portion where a plurality of charging ports 4 are provided, a coal loading car 6, which is an existing equipment, is removably mounted. The coal charging car 6 is mounted so that each exhaust passage 5 provided therein and the charging port 4 communicate with each other. The respective exhaust passages 5 are gathered together and communicated with a fixed duct 11 attached to the coal loading car 6. A furnace top cleaner blower 8 is attached to the upper part of the coal loading car 6. A gas blowing nozzle]O is connected to the blower 8 through a flexible tube 9. Moreover, the blower 8 is
It communicates with the furnace top cleaning filter 7. The gas blowing nozzle 10 is inserted into the carbonization chamber 1 from the charging port 4 via the exhaust passage 5. When the coal loading car 6 is used for normal purposes, the exhaust passage 5 is used as a dust collection duct, and the fixed duct 1 is used as a dust collector.

The effect when using a device having such a configuration will be explained.

First, a gas such as air, oxygen, or a mixture thereof is fed by a blower 8. The gas passes through the flexible tube 9, reaches the gas blowing nozzle 10, and is injected into the carbonization chamber 1. The injected gas stirs the inside of the carbonization chamber 1 to create an airflow. This air flow causes the gas to come into contact with the entire carbon 12 deposited inside the carbonization chamber 1. This gas is in the carbonization chamber 1
The combustion of carbon 12 adhering to the inside is promoted. Carbon 12 is combusted by oxygen in the gas and becomes carbon dioxide. Carbon dioxide generated as combustion gas rises within the carbonization chamber 1 and is discharged to the outside world from the charging port 4 through the exhaust passage 5. At this time, carbon dioxide is actively sucked in and exhausted by the fixed duct 11. At this time, carbon 12
By adjusting the charging port 4 to be opened in accordance with the deposition position of carbon, it is possible to change the air flow inside the carbonization chamber and remove carbon more efficiently. Further, dust generated during operation is also sucked by the suction device 6 and collected through the exhaust passage 5.

In this way, carbon adhering to the inside of the carbonization chamber 1 can be efficiently burned and removed while collecting dust.

[Effects of the Invention] As explained above, the coke oven carbonization chamber carbon removal device of the present invention can efficiently remove carbon adhering to the carbonization chamber using existing equipment without emitting dust to the outside world. It is something that can be done. Moreover, since existing equipment is used, the weight installed in the carbonization chamber can be reduced.
