Description

Detailed Description of the Invention

[0001]

This invention relates to a coke oven for medium and low temperatures.
Coke buckets for transporting red-hot coke, which is used when transporting red-hot coke that has been carbonized at (700 to 800 ℃) to a coke dry fire extinguisher, especially red-hot coke transport with a closed lid to prevent dust generation. The present invention relates to a method for discharging exhaust gas generated in a coke bucket.

[0002]

2. Description of the Related Art Red-hot coke which has been carbonized at a low temperature in a coke oven is transported to a coke dry fire extinguishing facility for extinguishing a fire. During the course of transportation, the coke being transported contains undry-distilled coke that has been dry-distilled only up to about 700 ° C, so a large amount of gas is generated, and due to the generation of this gas, it is emitted from the coke bucket. To dust.

As a conventional method for preventing dust from the coke bucket as described above, there is a method in which an openable lid is provided and the coke bucket is sealed and transported.
It is disclosed in JP-B-55-8036.

[0004]

However, in the method for transporting red hot coke disclosed in Japanese Patent Publication No. Sho 55-8036, a large amount of gas is generated in the coke bucket, so that the gas pressure in the coke bucket is reduced. There was a problem that the risk of gas explosion increased.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and does not generate dust and has no risk of gas explosion. The purpose is to provide an exhaust gas emission method.

[0006]

According to the present invention, there is provided a method for discharging exhaust gas in a coke bucket for transporting red hot coke, wherein the red hot coke transporting coke bucket having a closed lid is filled with the red hot coke, and then the coke car is closed. While transporting to the dry fire extinguishing equipment, the exhaust gas exhaust pipe of the exhaust gas exhausting device arranged between the coke oven and the dry fire extinguishing equipment faces the exhaust gas exhaust port provided on the lid of the coke bucket for transporting red hot coke. Stop the coke car and move the expansion part and / or the sliding part of the exhaust gas exhaust pipe tip forward to connect the exhaust gas exhaust port of the coke bucket for transporting red hot coke and the exhaust gas exhaust port, and then the exhaust gas exhaust port It was generated in the coke bucket for transporting red-hot coke by opening the opening and closing means provided in the and the suction device provided in the middle of the exhaust gas discharge pipe. Gas was aspirated, and discharges the exhaust gas.

[0007]

Operation: After the red hot coke is stored in the coke bucket for transporting the red hot coke on the coke car, the coke bucket is closed and the coke bucket is closed, and then the coke car is moved toward the coke dry fire extinguishing equipment.

[0008] In the moving coke bucket, exhaust gas is generated due to undry-distilled coke, and the gas pressure in the coke bucket increases as the amount of gas increases.

Therefore, the coke car is stopped at a position where the exhaust gas exhaust port provided in the lid of the coke bucket for transporting the red hot coke and the exhaust gas exhaust pipe of the exhaust gas exhaust device face each other. Then, the expansion portion and / or the sliding portion at the tip of the exhaust gas discharge pipe is advanced to connect the exhaust gas discharge port of the coke bucket for transporting red hot coke and the exhaust gas discharge pipe. The reason why the expandable portion and / or the sliding portion is provided at the tip of the exhaust gas exhaust pipe is to prevent the exhaust gas from leaking by minimizing the gap between the exhaust gas exhaust pipe and the exhaust gas exhaust port.

After the exhaust gas exhaust port and the exhaust gas exhaust pipe are completely connected and the exhaust gas does not leak to the atmosphere, the opening / closing means provided at the exhaust gas exhaust port is opened.

Then, the suction device provided in the middle of the exhaust gas discharge pipe sucks the exhaust gas generated in the coke bucket for transporting the red hot coke and discharges the exhaust gas.

When the exhaust gas is completely discharged, the opening / closing means provided at the exhaust gas outlet is closed, and the expansion / contraction portion and / or the sliding portion at the tip of the exhaust gas exhaust pipe is retracted, and the exhaust gas outlet of the coke bucket for transporting red hot coke is discharged. And separate the exhaust gas exhaust pipe. Then, the coke car is run again toward the dry fire extinguisher.

Since it is transported in this manner, it is possible to transport the red hot coke from the coke oven to the coke dry fire extinguishing facility without generating dust and without risk of explosion.

[0014]

EXAMPLE A coke bucket for transporting red hot coke used in the exhaust gas discharge method in a coke bucket for transporting red hot coke according to an embodiment of the present invention will be described with reference to FIGS. 1 (a) and 1 (b). FIG. 1 (a) is a side view of this coke bucket,
FIG. 1B is an enlarged view of part A of FIG.

As shown in FIG. 1 (a), this coke bucket has a bucket body 1 and a lid 2 and a lid 2 which can seal the bucket body 1 provided on the upper portion of the bucket body 1.
And the exhaust gas discharge port 3 provided in the.

As shown in FIG. 1B, an opening / closing valve 6 connected to a rotary shaft 5 horizontally supported by a supporting member 4 is provided at the tip of the discharge port 3 as an opening / closing device. By pushing the lever 7 connected to the rotary shaft 5, the lever 7 can be opened. Further, when pushing the lever 7 is stopped, the on-off valve 6 is provided with a counterweight (not shown), so that the on-off valve 6 is naturally closed.

A method of discharging the exhaust gas generated in the coke bucket will be described with reference to FIG. The discharge port 3 of the coke bucket is opposed to the exhaust gas discharge pipe 11 provided on the ground. Then, with the hydraulic or pneumatic cylinder 12 provided close to the exhaust gas discharge pipe 11 as the opening / closing means, the lever 7
Push the tip of to open the on-off valve 6.

Next, the sliding type connection pipe 13 provided on the exhaust gas discharge pipe 11 is pushed by the hydraulic or pneumatic cylinder 14 so that the tip of the connection pipe 13 is discharged from the discharge port 3 of the coke bucket.
Press on. Further, a bellows portion 15 is provided as a telescopic portion at the tip of the connecting pipe 13, so that exhaust gas does not leak from the connecting portion between the connecting pipe 13 and the discharge port 3 of the coke bucket.

After the above-mentioned state, the exhaust blower 16 provided in the exhaust gas discharge pipe 11 discharges the exhaust gas in the coke bucket.

When the exhaust gas discharge is completed, the connecting pipe 13 and the discharge port 3 of the coke bucket are separated in the reverse order of the above, and the pushing of the lever 7 by the hydraulic or pneumatic cylinder 12 is stopped, and the on-off valve 6 is closed. Put in a state.

Although dust is generated when the on-off valve 6 is opened and closed, this dust can be prevented by covering the connection pipe 13 and the discharge port 3 of the coke bucket with a hood. Further, in order to further reduce the risk of explosion, the lid 2 may be provided with a safety valve.

[0022]

According to the present invention, there is no danger of explosion,
Dust can be prevented from being generated from the coke bucket during transportation and the generated gas can be recovered.
