Description

A charging floar lid for monitoring carbonization and measuring temperature in a coke oven}

The present invention relates to an inlet lid of a coke oven, and in particular, the driver can safely and accurately determine the dry state of the coke in the coke oven without opening the riser and the inlet lid, and monitor the temperature change of the inlet in real time. It relates to a charging inlet lead installed infrared camera and advertising thermometer at the bottom so that it can be measured by.

1 schematically illustrates the operation of carbonizing coke in a coke oven. Coking the coke in the coke oven is performed by charging the coke oven after charging the anthracite coal into the coke oven through the charging hole 14, and extruding the coked coke after about 18 hours. It is an iteration of the process of charging the coal to newly dry carbon through the charging hole (14).

In the coke coking process, it is necessary to determine whether the coking coke has been sufficiently carbonized before extruding the coagulated coking coke. In order to determine whether the coherent coke has been sufficiently dried in the prior art, the rising pipe 50 is opened to check the state of residual gas, and then the charging inlet lead 70 is opened again so that the temperature of the carbonization chamber 10 having a temperature of 100 ° C. or higher. The inside of the charging vehicle (1) driver had to check with the naked eye. After the driver determines the dry state, the driver extrudes the extruder 20 and the transcar 30, and the extruder and the transska driver open the door to start the extrusion operation.

However, if the driver opens the riser 50 to check the dry state of the coke during the coke distillation, there is a risk that harmful residual gas generated during the coking of the coke is diffused into the air. Therefore, in order to prevent pollution, the gas flowing through the riser 50 is usually ignited to suppress the generation of noxious gas. In this case, however, there is a risk of burns and safety accidents during gusts, and the possibility of flame contacting the surrounding equipment increases the possibility of corroding the equipment. In addition, when the charging vehicle driver directly determines the dry state of the coke with the naked eye in the state where the charging lead 70 is opened, the high temperature, dust, and gas of 1000 ° C. or higher flow out, so that the driver of the charging vehicle 1 may not burn the image. In addition to the risk of wearing, there are many problems such as corrosion of the workbench exposed to COE by dust and gas.

Furthermore, in determining the dry state of the coke, the driver can visually identify the color and length of the gas flame ignited by the ascending pipe 50 to determine the dry state inside the carbonization chamber. Not only that, but also the gas ejection may adversely affect the inside of the carbonization chamber.

Therefore, it is possible to check the dry state of the coke being dried in the coke oven without opening the riser 50 and the charging inlet lead 70, and a technique for objectively determining the state inside the carbonization chamber is required. Was done. The present invention addresses these needs and overcomes the above-mentioned conventional problems.

Therefore, an object of the present invention is to provide a charging inlet reed in which an infrared camera and an advertising thermometer are installed so that the driver can safely check the dry state of the glowing coke without opening the rising pipe and the charging inlet lead.

Another object of the present invention is to improve the quality of the coke by providing an apparatus for objectively and accurately determining the dry state of the glowing coke in real time.

The charging frame 80 is a circular heat-resistant material, the outside of the frame is castable (castable) is designed to block the high heat applied to the frame in advance in the form of a square. As shown in the figure, according to the conventional charging inlet lead 70, the interior of the carbonization chamber is not visible, so that the charging inlet lead 70 is raised to open to check the dry state of the carbonization chamber. There is a need.

In addition, in the conventional case, in the state where the charging lead 70 is closed, the contact area between the charging lead 70 and the frame 80 is small, and the outer diameter of the bottom portion of the charging lead 70 is changed to the frame ( Since it was significantly smaller than the inner diameter of 80, a large gap existed between the bottom part of the charging inlet lead 70 and the frame 80. As shown in FIG. Therefore, there was a fear that gas would leak even in the state where the charging inlet lead 70 was closed.
