ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coke oven lid that is used to burn and remove carbon adhering to the walls and ceiling of a coke oven carbonization chamber.
コークス炉において、原料石炭を乾留してコークス化す
るに際し、発生する石炭ガスは、炭化室上部のガス排出
道から上昇管を介して集気本管に集められ、ブ。In a coke oven, when coking coal is carbonized into coke, the generated coal gas is collected from the gas discharge path in the upper part of the coking chamber into the air collection main pipe via the riser pipe.
ワーに吸引されてガス精製工程へ排送される。この石炭
ガス中に含有される炭化水素は、炭化室内および上昇管
内において一部熱分解され、カーボンが発生して炭化室
内および上昇管内に附着堆積する。The gas is sucked into the gas tank and discharged to the gas purification process. The hydrocarbons contained in this coal gas are partially thermally decomposed in the coking chamber and riser pipe, and carbon is generated and deposited in the coking chamber and riser pipe.

けやすく、カーボンの附着堆積が顕著である。In particular, the furnace temperature on the coke side of the carbonization chamber is higher than that on the machine side, and the coal gas generated is usually collected into the air collection main pipe via a riser pipe installed at the top end of the furnace on the machine side. It is more susceptible to thermal decomposition than the machine side, and carbon deposits are noticeable.

コークスの押出し‘こ際し、押止り、押語り等の原因と
なるばかりでなく、菱炭量が減少して生産性が低下する
。Carbon adheres to the walls of the carbonization chamber and as the deposition progresses,
When extruding coke, this not only causes stagnation and sluggishness, but also reduces the amount of coal and reduces productivity.

菱入炭のみを乾留する場合に比しカーボンの附着堆積が
著しい。Particularly in the briquette coal partial charging method, in which briquette molded under pressure using a binder such as pitch is mixed with the charged coal and carbonized,
The adhesion and accumulation of carbon is more significant than when carbonizing only the coal.

のカーボンを燃焼せしめ除去している。A conventional method for removing the force-bond deposited in the carbonization chamber is to press the coke inside the carbonization chamber for 14 cycles after pushing out the coke.
~ 2 special intervals) When empty, open the ascending pipe lid, and
The coal charging port farthest from the riser pipe is opened, and air is sucked in by natural draft from the coal bag port to burn and remove carbon on the ceiling and wall surfaces.

。However, with the above method, carbon cannot be sufficiently removed during the empty furnace time of the -cycle, and in particular, carbon adhering to the ceiling between the coke side and the coal charging port cannot be removed, and the carbon adhering to the furnace wall cannot be removed. In order to remove carbon from the lower part, not only the upper part of the furnace wall is overcooled and the furnace wall bricks are damaged, but also the furnace lid bricks used for operation are damaged due to thermal overload in the cold air. It has disadvantages such as:

ことが必要である。In order to eliminate the above drawbacks, high-temperature hot air is supplied from the kiln mouth furnace lid part opposite to the exhaust side such as the riser pipe and diffused throughout the carbonization chamber, and the heat load is changed to the operating furnace head. It is necessary to use a furnace lid lined with heat-resistant material that is less likely to be damaged by heat.

ある。An object of the present invention is to provide a furnace lid that can supply high-temperature hot air, has less damage due to thermal overload, and is optimal for burning off carbon.・In other words, the present invention involves drilling through holes in the upper and lower parts of a furnace lid lined with heat-resistant casta pull, connecting the through holes with a conduit via a blower attached to the furnace lid body, and supplying air to the suction side conduit of the blower. A furnace lid for removing carbon attached to a coke oven, which is equipped with a replenishment valve, and is lined with heat-resistant caster pulls to prevent damage due to thermal overload when the furnace is empty.
In addition, the high-temperature hot air inside the carbonization chamber is sucked in by a blower through one through hole drilled in the furnace lid, and the air is blown into the carbonization chamber through the other through hole along with the air sucked in from the air supply valve. This prevents cooling and makes it possible to supply high-temperature hot air from the kiln opening on the opposite side to the exhaust side of the riser pipe, thereby achieving air diffusion throughout the entire carbonization chamber.
したがって、従来ーサィクルの空窯時間では困難であっ

傷することがなく、しかも、操業用炉蓋煉瓦を損傷せし
めることがない等の効果が得られる。Therefore, it is possible to sufficiently remove adhering carbon from the ceiling near the coke side, which was difficult during the empty kiln time of conventional cycles, and to prevent overcooling of the furnace wall and damage to the furnace wall bricks. , effects such as not damaging the operating furnace cover bricks can be obtained.
なお、炉蓋本体に取付けするブロワーは、高温熱空気の
吸込み位置を切替できる耐熱型で正逆回転型のものが、
炭化室内での空気の拡散をより良好ならしめるから有利
であり、また、導管は、熱空気の温度低下の防止、危険
防止のため保温材を施工すべきである。The blower attached to the furnace lid body is a heat-resistant type that can switch the suction position of high-temperature hot air, and is a forward-reverse rotating type.
This is advantageous because it allows for better air diffusion within the carbonization chamber, and the conduit should be provided with a heat insulating material to prevent the temperature of the hot air from dropping and to prevent danger.
