る技術が知られている。(Prior Art) Carbon is firmly attached to various parts of a coke oven carbonization chamber during coal carbonization. If left unattended, carbon adhering to the furnace wall surface will not only make it difficult to push out the coke, but also cause a decrease in the effective volume of the carbonization chamber and a decrease in the thermal conductivity of the furnace wall, so periodic removal work is necessary. . Furthermore, carbon adhering to the top surface (ceiling surface) of the coking chamber and the top surface of the furnace wall, if left unattended, will make leveling when inserting the coal difficult, so periodic removal work is still necessary. Further, carbon adhering to the base of the riser pipe and the riser pipe portion requires periodic removal work because if left unattended, it will become difficult for the generated gas to escape. Therefore, conventionally, in order to remove carbon adhering to the furnace wall surface, a spear-shaped jig with a sharp tip and a length of 5 to 6 m was used, as described in Japanese Patent Publication No. 60-2348. It is common to use this method and push it down from the top of the furnace by hand. However, this method has the basic disadvantage that the carbon layer completely peels off from the furnace wall, impairing the sealing function of carbon at the furnace wall joints. There are drawbacks such as production work being stopped during the push-off work. Furthermore, it is difficult to push off carbon adhering to the top surface (ceiling surface) of the carbonization chamber and the top surface of the furnace wall because it forms a blind spot from above the furnace. As an alternative to this operation, there is a known technique in which the charging port and riser pipe of the carbonization chamber are opened approximately one hour before extrusion, and air is introduced into the carbonization chamber through natural ventilation to burn and remove adhering carbon.

Coke oven gas of m 3 /Hr.Coalt (at 4800kcal /Nm 3 ) is being generated, and if the carbonization chamber is opened at this point, the coke oven gas will be released from the riser pipe along with the introduced air, which will cause problems. This method is economical, and the coal charging port where air is introduced is cooled, causing damage due to spalling and the like. Furthermore, carbon adhering to the base of the riser pipe and the riser riser pipe can be removed by combustion with the air introduced from the charging port mentioned above, or by opening the leveling cap before coke extrusion to introduce air and burn it. Alternatively, the riser pipe is mechanically pushed down from the top of the riser pipe, but in either case, the coke oven gas generated during this time is released.

By injecting a gas containing gas and swirling and stirring the gas along the wall of the carbonization chamber, it is possible to effectively burn and remove the adhering carbon on the entire surface of the wall of the carbonization chamber. By selecting the conditions for the jet flow, we are able to maintain the sealing properties of the adhering carbon joints, which is important in the carbonization chamber, and to maintain the soot concentration from the chimney at a certain level or less when charging coal. It has also been found that only undesirable excess adhered carbon can be removed without causing a local temperature drop, and that the extrusion current necessary for extruding coke from the carbonization chamber can be kept below a certain value.

The present invention provides an extremely superior combustion removal device that has never been realized before.

付着カーボンを残すことができる。 According to the device of the present invention, the injection nozzle of the insertion lance is arranged so that the injection direction is substantially parallel to the side wall surface of the carbonization chamber, so that the oxygen-containing gas injected from the nozzle follows the side wall surface. This method generates a swirling airflow in the carbonization chamber and brings it into contact with the carbon adhering to the carbonization chamber wall to burn and remove it.The jet stream is not applied directly to the wall to remove the adhering carbon, so it does not damage the wall surface. Excessive carbon adhering to the wall surface is uniformly burned and removed, leaving the adhering carbon necessary for the sealing function of the furnace wall joints.

This facilitates swirling and stirring of the airflow ejected from the nozzle, and also makes it possible to increase the temperature of the ejection airflow.

This gas is composed of oxygen, air, or a mixture thereof, and can be any gas that contains oxygen, and may be enriched with oxygen to further suppress the temperature drop in the carbonization chamber 4. . In addition, in the present invention, the means for inserting the lance 1 is not limited to one using the lance guide 7 and the winding drum 10, etc., but may also be a commonly used grasping and lowering method, for example, a lifting/lowering system using a suspension device or a simple hanging method. good. Furthermore, the trolley may be of a fixed self-propelled type or may be towed by a loading vehicle.

好ましい結果が得られる。 In order to burn and remove adhering carbon in the carbonization chamber 4 using the device configured in this way, for example, at least one charging hole 11 is opened in the carbonization chamber 4, and the inside of the carbonization chamber 4 is opened from the charging hole 11. The lances 1 described above are inserted in the number corresponding to the open charging hole 11 and to about 1/4 to 3/4 of the depth of the carbonization chamber 4. Next, from the nozzle 2 which injects water approximately parallel to the side wall surface of the carbonization chamber 4.
A gas containing oxygen or extracted oxygen is injected at a high speed of 20 m/sec or more to swirl and stir the inside of the carbonization chamber 4. If this flow velocity is less than 20 m/sec, the removal efficiency will decrease or vary. For these reasons, the high-speed injection of gas differs slightly depending on the furnace width of the carbonization chamber 4, etc., as shown in FIG. Therefore, π index π = kinetic energy of ejected air / viscous resistance of gas = ρU p l 2 /μL where ρ: gas density μ: viscosity coefficient U p : ejection flow velocity l: furnace width L: effective removal range It is preferable to vary the flow rate of the ejected gas so that the index value is 0.6 or more, since swirling and stirring are optimized, resulting in a combustion removal effect and stabilization of the temperature in the carbonization chamber. Furthermore, as shown in Fig. 4, the lance 1 inserted from the charging hole 11 also injects gas starting from the upper limit of the carbonization chamber 4, and then at the middle and lower limits, depending on the distribution or amount of carbon deposited in the carbonization chamber 4. If the jet is moved up and down at the same time, favorable results can be obtained due to the swirling flow of the jet flow.

Alternatively, the riser route may simply be used. Furthermore, as shown in FIG. 5, by connecting the exhaust gas guiding duct 15 to the charging hole 11 into which the lance 1 is not inserted, and connecting the other end to the suction side of a blower, the supply gas (oxygen A part of the exhaust gas can be mixed with air or a mixture thereof), which promotes swirling and stirring of the fluid jetted from the nozzle 2 throughout the entire interior of the carbonization chamber 4, and increases the temperature of the fluid jetted out. can be carried out, and favorable results can be obtained.

An insertion port dedicated to the lance may be set at the top of the furnace or at the top of the furnace. Alternatively, a dedicated insertion opening may be provided in the furnace lid and a lance may be inserted into this opening.

Regarding the protruding direction and shape of the nozzle, those shown in FIG. 7 can be used, but in both cases, a swirling stirring flow is formed along the side wall of the carbonization chamber.

にデツドスペースが生じないように配慮される。 Preferably, some of the nozzles protrude at a constant slope with respect to the bottom of the carbonization chamber, so that no dead space is created within the carbonization chamber.
