Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas leakage monitoring apparatus and a coke oven including the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas outflow monitoring apparatus and a coke oven facility including the same, and more particularly, to a gas outflow monitoring apparatus and a coke oven facility including the same, which can monitor a gas outflow from a pipe .

Generally, the coke used as a means of ensuring air permeability as well as a role of a heat source, a reducing agent, and the like in the blast furnace is produced by carburizing a blend containing coking oven, for example coal, in a coke oven facility.

Here, each of the combustion gas supply unit, the air supply unit, and the exhaust unit is composed of a plurality of pipes.

The coke oven includes a carbonization chamber in which coal is charged, and a combustion chamber located at one side of the carbonization chamber and indirectly heating the carbonization chamber by burning the combustion gas with air.

In the combustion system in the coke oven facility, the combustion gas and air supplied from the combustion gas supply unit and the air supply unit are supplied to the combustion chamber. The coke is produced by the heating of the carbonization chamber by the heat generated in the combustion process and the coal being carbonized. The waste flue gas generated in the combustion process is discharged to the stack through the exhaust part.

Here, the combustion gas supply unit is composed of several hundred pipes, and a plurality of pipes are connected to each other through a flange, and are commonly referred to as a basement.

On the other hand, when the flange is broken or the flange is loosened by the heat of the gas generated in the coke oven, the combustion gas passing through the pipe flows out into the gap of the flange. However, in the basement, there is only a sensor that generates a gas leakage alarm when the gas concentration is above a certain level, and it is not possible to know which gas has leaked from any pipe or flange. Therefore, it is difficult to check the piping and the flange, and there is a problem that the inspection is delayed. In addition, there is a risk that the operator may suffocate by gas when the worker goes in and out of the basement in a state where the inspection is delayed and the outflow of gas is continued, and there is a risk of fire and explosion if the gas outflow is left for a long time.

If the gas flows out from any one of the connection portions between the plurality of combustion gas pipes 210 or the plurality of connection portions 220 during the movement of the combustion gas mixture gas, It can be seen from which combustion gas piping 210 the gas flows out. That is, the outflowed gas escapes to the housing 510 of the gas outflow monitoring apparatus 500 installed at the corresponding position. Then, the gas in the housing 510 moves to the collecting member 522 of the gas collecting unit 520, and the collecting member gradually expands as the gas flow rate increases. The operator checks the expansion and expansion amount of the plurality of collecting members 522 while checking the installation positions of the plurality of combustion gas piping 210 and determines the position of the combustion gas piping 210 or the connection site Able to know.

The operator is able to visually confirm whether the collecting member 522 is inflated or inflated. Thus, for example, in a configuration including a plurality of piping through which gas flows, for example, in a gas supply unit 200 or an exhaust unit 300, it is possible to know which gas is flowing out from a pipe connection portion, .

In particular, the combustion gas supply part 200 of the coke oven facility is installed in a closed basement. By installing the gas outflow monitoring device 500 according to the present invention, the gas outflow position and the gas outflow amount can be easily confirmed, Maintenance is possible. Accordingly, it is possible to prevent the occurrence of a safety problem due to gas leakage.
