Description

Port device and system for operating port device {POT APPARATUS AND SYSTEM FOR OPERATING POT APPARATUS}

An embodiment relates to a port device, and more particularly, to a system for operating a port device and a port device capable of prompt recognition and handling of a gas ejection accident.

In general, by-product gas such as Blast Furnace Gas (BFG), Coke Oven Gas (COG), and converter gas (Linz Donawitz Gas: LDG) generated during operation in a steel mill is transport pipe. Used factory. Since these by-products contain a large amount of moisture, dust, and contaminants, they interfere with the flow of gas in the conveying piping and cause corrosion of the conveying piping and serious equipment failure in the used plant. To this end, a seal pot device is installed and operated to penetrate impurities through the bottom of the transfer pipe for every 100 m to 150 m of the transfer pipe to deposit impurities.

1A to 1B are views showing a port device according to the prior art, and FIGS. 2A to 2B are views for explaining an operation state of the port device shown in FIG. 1.

1A to 1B, the port device 60 according to the prior art includes a drain pipe 10, a port body 50, and an overflow pipe 30 connected to the gas transfer pipe 1 Includes. The port device 60 is maintained in a state where water is contained to a certain height inside the overflow pipe 30, and the water inside is designed to maintain a head pressure corresponding to 1.5 times the gas pressure in the transfer pipe 1 . The port device 60 blocks the gas outflow in the transport pipe 1 using water, and when water and other impurities fall through the drain pipe 20 due to a specific gravity difference, and collects in the lower port body 50 Finally, it is discharged to the outside through the overflow pipe (30).

Conventional port device 60 is provided with a plurality of, may be installed in different transfer pipes, for example, each of the plurality of port devices (60A, 60B, 60C) as shown in Figure 1b, each of the BFG transfer pipe, COG transfer It can be installed to be connected to the pipe, the transfer pipe for LDG.

Referring to Figures 2a to 2b, the conventional port device 60 is capable of performing its function when there is a prescribed amount of water as shown in Figure 2a, but the water inside is lost due to some reason and is insufficient When the pressure of the head that blocks the internal gas is lost, the gas is ejected to the outside, or when the pressure of the gas being transferred changes rapidly and rises above the specified pressure, the water that blocks the internal gas at the head pressure It is pushed out and the balance of head pressure is lost, causing a dangerous accident in which gas is ejected to the outside.

However, in the case of Gwangyang Works, BFG pipes, COG pipes, and LDG pipes are installed in the Gwangyang Works, where the length of the transfer pipe for by-product gas installed throughout the steelworks is through, and through the bottom of the transfer pipe for each length of 100 m to 150 m In order to prevent impurities from depositing and removing, a seal pot device is installed and operated, and there are many difficulties in management because the type of gas being transferred is different and the pressure of the gas is also different for each transport pipe.

In addition, even if an accident occurs in which the gas is ejected from the port device 60, it is impossible for the worker to immediately detect it, and the worker accidentally checks it with the naked eye or the gas is measured by the gas detector installed in the peripheral equipment to find the gas leakage point. It is most often found in. The only method for the worker to check the presence or absence of the abnormality of the plurality of port devices 60 is the only method for directly inspecting one by one with the naked eye. At this time, when the gas ejection of the port device 0 is confirmed, evacuate the surrounding personnel, wear an air respirator and a hazardous chemical handling suit, and install a manual shutoff valve 20 installed in the drain pipe 10 of the port device 60. Completely enclosed to block the ejection of gas and condensate, and then inject water into the port device 60 to set the proper level, and when the gas pressure is normalized, deploy the blocking valve 20 of the drain pipe 10 to develop a normal port device ( 60) as a function.

However, such a conventional inspection method requires performing a series of cumbersome and dangerous tasks as described above, while it is impossible to immediately recognize the port device 60 located in a remote and invisible location at the time of ejection. In the port device 60 for a long period of time, gas ejection is left unattended for a long period of time, resulting in the risk of fire explosion and gas poisoning due to the leakage of toxic and flammable gases, and environmental pollution due to the leakage of contaminated water. A problem is occurring.
