DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for suppressing dust generation during coke extrusion in a coke oven furnace.

[0002]

2. Description of the Related Art Conventionally, red hot coke carbonized in a coke oven carbonization chamber is extruded from a carbonization chamber by an extruder, passes through a guide grid of a coke guide car, and is collected by a bucket car. When the cake passes, falling of the red hot coke mass due to the collapse of the coke cake and dusting due to the rolling occur. As a countermeasure against this dust generation, it is a fact that the dust is collected by a dust collecting device in a dust collecting hood of a coke guide vehicle.

[0003]

As described above, no measures have been taken to suppress the generation of dust from falling and rolling of the red hot coke mass due to the collapse of the coke cake, and only the dust collection from the dust collecting hood of the coke guide vehicle is performed. In addition, the generation of dust due to the collapse at the initial stage of extrusion is the largest, and the deterioration of the environment during coke extrusion is a problem in actual operation.

[0004]

Means for Solving the Problems The inventors of the present invention have intensively developed to solve such a problem, and as a result, the coke cake is prevented from falling due to collapse of the coke cake during extrusion by installing a coke drop impact mitigation plate. Invented is a dust generation suppressing device which aims to avoid dust generation due to falling powder, which is the largest factor of dust generation during extrusion. Coke that where mode of the invention is to receive the suppression <br/> win apparatus dust generation during coke oven extrusion, the red-hot coke extruded from a coke oven carbonization chamber to guide the lattice near the inlet of the coke guide car Arrange a drop impact mitigation plate, coke

There is provided a device for suppressing dust generation during coke oven extrusion, wherein a mechanism for horizontally moving a plate is provided .

[0005]

The present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic view showing the operation principle of a coke drop impact mitigation apparatus according to the present invention and a coke collapse state. FIG.
(A) shows a state before extrusion, in which a red hot coke 1 carbonized in a coke oven carbonization chamber is in a state immediately before being extruded by an extruder. A coke bucket truck 4 is provided under the dust collecting hood 2 and is constituted by the hood 2. Further, at the glow coke receiving port in the dust collecting hood 2, the coke drop impact mitigation plate 5 according to the present invention is fixed to the support plate 6 of the upper receiving plate near the entrance of the coke guide vehicle guide lattice. It is locked by a detachable hook 7.

FIG. 1 (B) shows a state immediately after the extrusion, in which the red hot coke 1 carbonized in the coke oven carbonization chamber is extruded from the coke side kiln mouth by the extrusion ram 8 and the inside of the guide wheel gauge is synchronized. Hits the flexible coke drop impact mitigation plate 5 attached to the coke. The coke drop impact mitigation plate 5 is integrated with the coke guide vehicle guide grid entrance upper portion while suppressing the falling from the top of the red hot coke. When the support plate of the receiving plate fixed to is moved in synchronization with the movement of the red hot coke, the support plate slides forward in the direction of the extrusion to form an initial coke collapse prevention state 9.
Also, the bottom of the gauge inlet of the coke drop impact mitigation plate 5 which has been locked by the detachable hook 7 is pushed by the red hot coke and comes off from the detachable hook 7.

FIG. 2 is a schematic diagram showing the operating principle of the coke drop impact mitigation apparatus according to the present invention and the coke collapse state similar to FIG. FIG. 2A shows a process in which red hot coke is extruded and passes through a guide lattice.
(B) shows a state in which red hot coke is extruded and is being loaded on a coke bucket truck. That is, the red hot coke 1 is extruded by the extrusion ram 8, while the extruded red coke 1 moves while the coke drop impact mitigation plate 5 synchronizes with the extrusion in the guide lattice, and stops at the guide lattice tip position. The lower portion is free from the desorption hook and moves with the movement of the red hot coke in a free state, and the red hot coke is loaded on the coke bucket truck while maintaining the falling coke prevention state 10.

FIG. 3 is a view showing a state of mounting a coke drop impact reducing plate according to the present invention. FIG. 3A is a longitudinal sectional view, in which the upper part of the coke drop impact absorbing plate 5 is fixed to the support plate 6 of the receiving plate and the lower part is the detachable hook 7 as described above.
It is locked to. When the red hot coke in the carbonization chamber 11 is extruded by the extruder, the upper part of the coke drop impact mitigation plate 5 is supported by the support plate 6 of the receiving plate by the operation of the support plate moving device 12 in accordance with the movement of the extruded red coke. The lower part is disengaged from the desorption hook 7 and the lower part of the coke fall impact absorbing plate 5 is pushed and moved like a pendulum together with the movement of the red hot coke, thereby preventing collapse of the red hot coke at the time of receiving the bucket. is there. FIG.
(B) is a top view which shows the mounting condition of the coke fall impact-reducing board which concerns on this invention. The support plate of the receiving plate has shown the state at the time of moving to a guide grid. Reference numeral 13 denotes a backstay.

FIG. 4 is a view showing the structure of a coke drop impact reducing plate according to the present invention. FIG. 4 (A) shows a flexible iron plate type coke drop impact mitigation plate, in which a heat-resistant iron plate 14 is continuously connected by a pin connection 15 and has, for example, one flexible plate having a width of about 400 to 500 mm. Formed. FIG. 4B shows a flexible rod type, in which a heat-resistant rod 16 is continuously connected by a pin connection 15 in a lattice shape. FIG. 4
(C) is a flexible chain type. These are not limited to the above examples as long as they are made of a heat-resistant material and are configured in a flexible shape.

As described above, since the flexible coke drop impact absorbing plate moves while pressing the red hot coke at the time of extruding, the falling collision of the lump coke to the coke bucket truck due to the collapse of the coke cake is soft-landed, and It was possible to prevent the generation of dust due to falling dust, which was the biggest factor of dust generation.

[0011]

As described above, according to the present invention, it is possible to suppress the collapse of red-hot coke and the generation of a large amount of dust due to dropping at the initial stage of extrusion on the side of a coke guide vehicle, and also to ensure the safety of work. This is an extremely excellent effect that can ensure the safety of operation.
