器に接続されている従来の開放型冷却水循環系は
除去してボイラ型冷却水循環系を接続している。 The cooling method of the gas cooler in the converter exhaust gas treatment equipment has conventionally been an open cooling method, but in recent years there has been an increasing number of conversions to the boiler method as an energy saving measure for the sensible heat of the converter exhaust gas. In this case, the conventional open cooling water circulation system connected to the gas cooler is removed and a boiler type cooling water circulation system is connected.

短縮され、生産性が低下するものである。 If the boiler method is used as the cooling method for the gas cooler, periodic inspections of the boiler will be required, and during periodic inspections, the operation of the converter must be suspended for about a week, and the boiler drum, circulation pump, piping, etc. Even if a boiler auxiliary machine breaks down, the operation of the converter must be suspended, which shortens the operating time of the converter and reduces productivity.
一方、従来の開放型冷却水循環系を除去し廃棄
するのは、時間と費用がかかるばかりではなく、
今だ使用できるのであるから二重の損失となるも
のである。 On the other hand, removing and disposing of traditional open cooling water circulation systems is not only time-consuming and expensive;
Since it can still be used, this is a double loss.
本発明は、かかる諸事情に鑑みなされたもの

This paper attempts to present a cooling water circulation method that allows continuous operation of the converter by switching the circulation system of the converter.

行わせる。 Next, a cooling water circulation method using the cooling water circulation system of the gas cooler having such a configuration will be explained. During normal operation of the converter, the cooling water of the gas cooler 1 is circulated through the boiler-type cooling water circulation system 9. That is, the steam and water mixture obtained by cooling the converter exhaust gas in the gas cooler 1 is put into the boiler drum 10 to separate steam and water, and the steam is sent to the accumulator through the steam piping 12 to separate the steam and water. The cooled water is sent to the gas cooler 1 by the circulation pump 11 to cool the converter exhaust gas again.

る。 During periodic inspections of the boiler and in case of failure of boiler auxiliary equipment such as the boiler drum, circulation pump, piping, etc., close the stop valves 13, 13' of the boiler type cooling water circulation system 9, or close the short pipes 15, 15' shown in Fig. 2. Remove and install blind plugs, and stop valves 7, 7', of open cooling water circulation system 2.
8, 8' or by removing the blind plug and attaching the short pipes 14, 14' as shown in FIG. 2, the cooling water of the gas cooler 1 is circulated through the open cooling water circulation system 2. That is, the hot water obtained by cooling the converter exhaust gas in the gas cooler 1 is put into the water collection tank 3, and from there it is sent to the cooling tower 4.
and cooled and placed in the water supply tank 5.
The cooling water inside the converter is sent to the gas cooler 1 by the cooling water supply pump 6 to cool the converter exhaust gas again.

る。 During this period, the boiler drum 10, circulation pump 11, circulation piping, and other boiler auxiliary equipment of the boiler-type cooling water circulation system 9 are inspected, and the operation of the converter is suspended only when the gas cooler 1, which is the boiler body, is inspected. Therefore, the operational stoppage of the converter during periodic inspection of the boiler is extremely short, and the decrease in productivity is minimized.

産性が向上する。 Furthermore, even if a failure occurs in the boiler auxiliary equipment such as the boiler drum 10, circulation pump 11, circulation piping, etc., the cooling water of the gas cooler 1 can be circulated through the open cooling water circulation system 2 in the same way as during regular inspections of the boiler. This allows the converter to continue operating without any interruptions, improving productivity.

等の効果がある。 As detailed above, the cooling water circulation method for the gas cooler in the converter exhaust gas treatment equipment according to the present invention is to add a boiler type cooling water circulation system to the existing open type cooling water circulation system, and to change the valve or short pipe. Since the cooling water circulation system is switched by removing the boiler, by switching the cooling water circulation system to an open cooling water circulation system during regular inspections of the boiler, it is possible to shorten converter operation stoppages to only during inspection of the gas cooler. productivity can be minimized. In addition, even if a boiler auxiliary equipment malfunctions, the cooling water circulation system can be switched to an open cooling water circulation system in the same way as during regular boiler inspections, allowing converter operation to continue without any interruptions and production. Improves sex. Furthermore, since the existing open-type cooling water circulation system can be used effectively, the time and expense of removing and disposing of it are also eliminated.
