Description

Gas induction device of coke oven carbonization chamber

The present invention relates to a device for inducing gas generated in a carbonization chamber of a coke oven, and more particularly, to build a duct so that a plurality of flow paths are formed to smoothly guide gas generated in the carbonization chamber to an upward observation. The present invention relates to a gas induction apparatus of a coke oven carbonization chamber which is equipped with a pipe member to prevent vortex phenomena and internal pressure rise, thereby reducing pressure on the oven door, and preventing outflow of gas through the oven door and the door frame.

In general, as shown in FIG. 1, a coke oven facility 100 of a steel mill is provided with a carbonization chamber 110 into which a coal 9 is charged through a charging hole 112, and the carbonization chamber 110. Oven door 130 of the total 132 doors are provided in the air-sealed door so that the coke and coke oven gas (hereinafter referred to as gas) on both sides of the carbonization chamber 110 does not leak to the outside. Structured, the oven door 130 is installed on the side by a transfer car (not shown), and the oven door 130 is installed on the push side (Pusher) (not shown) It is closed and opened for repeated extraction and replacement.

And, as shown in FIG. 2, the oven door 130 is a door body 131 made of cast iron, a heat insulation edge 132 built on the inner surface and a plurality of strong fire-resistant brick member Fire door kit 133, the oven door 130 installed on the side is line-up to the oven roof (Oven Roof), while the oven door 130 installed on the pusher side is a leveler door ( Only the bottom of the leveler door 133a is lined up. The fire retardant 133 having a predetermined height is fixed by a metal holder fixed to the entire door body 131.

The production of high-strength coke using the coke oven equipment 100 is usually charged with 32 tons of powder through the charging hole 112 into the carbonization chamber 110 having a height of 7 m and a width of 43 m. Coal 9 is charged at a temperature of about 1300 ℃ for 9 to 19 hours by coagulation by coagulation, where the gas generated in the carbonization chamber 110, the gas collecting unit 160 through the riser 150 It is sent through the Mars process.

However, when the coke oven facility 100 increases the operation rate of the coal in the carbonization chamber 110 as the operation rate increases, the amount of gas generated per unit time also increases, reducing the efficiency of chemical conversion and returning during flat work by the pusher. Since the gas way is sealed due to the collapse of the coal 9 charged during the powdering and drying process, gas to be discharged to the outside through the riser 150 stays inside the carbonization chamber 110. While increasing the internal pressure, due to this vortex phenomenon occurs in the door frame joint 140 and the charging inlet 112, the stress is concentrated in the oven door 130 to increase the repair period, leading to premature damage There was a problem.

In addition, a large amount of tar formed in the coke distillation process blocks the gas flow path of the door frame 141 so that the gas inside the carbonization chamber 110 is leaked to the outside along with the flame by the vortex phenomenon, In addition to making it difficult to enter and detach 130, there was a problem of contaminating the air environment.

Therefore, the present invention is to solve such a conventional problem, the object is to build a brick member so that a plurality of flow paths can be formed to smoothly guide the gas generated in the carbonization chamber to the upward view, and the pipe member The present invention provides a gas induction device for a coke oven carbonization chamber that can prevent eddy currents and internal pressure rise to weaken the pressure on the oven door and prevent outflow of gas through the oven door and the door frame.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Gas induction apparatus 1 of the coke oven carbonization chamber according to the present invention, as shown in Figures 3 to 5, the oven door by the gas generated during the drying process of the coal (9) charged into the carbonization chamber 110 As to form a passage for inducing the flow of gas inside and outside of the oven door 130 so as to make it difficult to enter and remove the 130, or to prevent the outflow of the gas, and thus environmental pollution, The apparatus 1 consists of a first gas induction part 10 and a second gas induction part 20.

That is, as shown in FIGS. 3 and 4, the first gas induction part 10 provided on the outer side of the oven door 130 includes a retainer lid 134 that surrounds the lower end of the oven door 130. The through hole 11 of a predetermined size is formed in the center of the lower surface of the bottom bar, and the inlet is in contact with the through hole 11 so that the gas generated inside the carbonization chamber 110 is initialized from the bottom to the top. It is provided with a cylindrical nozzle 12 that can be introduced, one end of the nozzle 12 is connected to the 'U' shaped gas collecting pipe 14 via the flange (13).

Further, each of the distribution pipes 14a and 14b of the gas collecting pipe 14 is mounted so as to replace each of the induction discharge pipes 16 as the union nuts 15, and the induction discharge pipes 16 are separate. It is firmly supported and supported by a support (not shown), and each upper end of the induction discharge pipe 16 is perforated on the outer surface of the door body 131 of the oven door 130 so as to communicate with the upper space of the carbonization chamber 110. As it is connected to the formed connection hole 16a, the lower side gas inside the carbonization chamber 110 introduced through the nozzle 12 is connected to the through hole 11 and installed outside the oven door 130. The air is automatically blown to the upper side of the inside of the carbonization chamber 110 through the induction exhaust pipe 16 by a pressure difference, and then the continuous pipe passes through the rising pipe 150 and the gas collecting unit 160 installed on the carbonization chamber 110. Is sent to the Mars process.

In addition, the outer surface of the induction discharge pipe 16 is insulated so that the tar formed in the pipe due to the temperature deviation is not solidified, and made of aluminum material should be maintained in the airtight atmosphere according to the purity, while the inside of the pipe in the middle It is equipped with a purge valve (Purge Valve) (17) to easily remove the tar (Tar) formed inside by adjusting the flow rate of the flowing gas.

Meanwhile, as shown in FIGS. 3 and 5, the second gas induction part 20 provided inside the object door 130 is perpendicular to the inner surface of the insulation edge 132 for blocking the heat of dissipation.
