Description

Apparatus for sealing the leakage portion in the door of the coke oven}

The present invention relates to a gas leak point sealing device of a coke oven mobile device carbonization chamber door, and more specifically, the operator is left to seal and work environment by direct COG gas discharge to the carbonization chamber door frame when the coke oven carbonization chamber is charged. Coke that can quickly respond to the real environmental pollution problem by installing sealant automatic injection device composed of a series of processes on mobile devices in a working environment where pollution and workers are exposed to harmful substances, and then sealing the door frame gas emissions rapidly. The present invention relates to a gas leak point sealing device for an oven moving device carbonization chamber door.

First, the work process of the coke oven, as shown in Figure 1, is charged in the oven carbonization chamber 11 and charged at a temperature of about 1200 ℃ to 1300 ℃ for a certain time, for example, about 17 hours or more. It is a process of making coke by distilling the coal. Coke is extracted to the outside through the door 12 of the coke oven. The carbonization chamber 11 is sealed when the coal is dried, and the door 12 is opened when the coke is extracted.

As described above, in order to carry out a coke oven work process in which coal charging and coke extraction are repeatedly performed, it is required to have a mobile device facility for opening the carbonization chamber door 12 and extracting coke. In addition, such a mobile device is equipped with an extruder 14 for extracting coke from the carbonization chamber 11, a charging car (not shown) for charging coal into the carbonization chamber 11, and a transport car 15 for guiding red coke. ) And a fire extinguisher 16 for cooling and extinguishing the extracted red coke.

According to the planned work plan, the coke formed in the carbonization chamber 11 by carbonizing the coal charged into the carbonization chamber 11 by the charging vehicle is transferred to the fire extinguisher 16 by the extruder 14 via the transport car 15. Extracted. Then, the coke cooled by the fire extinguisher 16 is transferred to the blast furnace through a transfer line is used as a heat source.

In such a work process, after coal is charged into the carbonization chamber and carbonized, the COG (coal generating gas) is generated in the carbonization chamber 11 until the coke is extracted, and the generated gas is collected and purified for combustion. It is reused as a heat source as a gas. In order to prevent the gas from being discharged to the outside, a sealing strip 20 is attached to the door frame 18 and the door 12.

However, as shown in FIG. 2, as the coke operation increases, the sealing strip 20 deforms or burns out, so that the gas 17 generated in the carbonization chamber 11 stands by at the door frame 18 side. Problems are discharged to. Therefore, the problems of environmental pollution and harmful substances discharge in the coke operation has been raised, it is required to seal the door 11 and the door frame 18 using a sealant in order to solve these problems.

Since the sealing work on the door 11 and the door frame 18 is performed by a worker's hand, the sealing work efficiency is reduced, and also harmful substances such as CTPV (carcinogenic material) contained in coal generating gas are reduced. Workers are exposed directly and environmental pollution issues are emerging.

The present invention was devised to solve the conventional problems as described above, and after mixing water glass (WATER GLASS), which is a carbonization chamber door gas sealing material, with water, spraying directly on the gas discharge part of the coke oven door frame to effectively seal the work. The purpose of the present invention is to provide a gas leak point sealing device for a coke oven door that can prevent leakage of coal generated gas inside a carbonization chamber to the outside and prevent workers from being exposed to coal generated gas. There is this.
