Description
本發明為一種冷卻水切換接管裝置及其操作方法，特別是有關於一種即時切換兩種不同冷卻水於高爐冷卻系統的冷卻水切換接管裝置及其操作方法。The invention relates to a cooling water switching connection device and its operating method, in particular to a cooling water switching connection device and its operating method for instantly switching two different cooling waters in a blast furnace cooling system.
高爐在操作時，必須考慮到冷卻壁可能會因為爐料磨耗熱面而有漏水的情況，因此會在每一組冷卻壁之出水管上設置壓力錶，利用關斷入水管上的手動閥與出水管之手動閥，觀察壓力錶是否有壓降情況。例如，當壓力錶之壓力降至接近爐內壓力時，表示該串冷卻壁水道可能至少一處已磨損漏水，以致與爐內相通，其壓力值才會與爐內壓力相近，按著，就必須持續注意軟水密閉循環系統中膨脹水箱之失水率，若失水率大於預設值時，則須停爐檢修該處冷卻壁水道，避免因漏水過多而影響爐熱。When the blast furnace is in operation, it must be considered that the stave may leak due to the wear of the furnace material on the hot surface. Therefore, a pressure gauge will be installed on the outlet pipe of each group of staves, and the manual valve on the inlet pipe and the outlet pipe will be shut off. For the manual valve of the water pipe, observe whether there is a pressure drop on the pressure gauge. For example, when the pressure of the pressure gauge drops to close to the pressure in the furnace, it means that at least one of the stave channels in the series may have been worn and leaked, so that it communicates with the furnace, and the pressure value will be close to the pressure in the furnace. Continuous attention must be paid to the water loss rate of the expansion tank in the soft water closed circulation system. If the water loss rate is greater than the preset value, the furnace must be shut down for maintenance of the stave water channel at this place to avoid affecting the furnace heat due to excessive water leakage.
而隨著爐內爐料持續下移，可能會造成原破漏處繼續磨耗而擴大，也有可能磨耗其他冷卻壁而產生新的破漏點。意即當軟水失水率進一步提高時，對現有的水系統而言，並無法判別是那種情況造成的。因此，必須再進行全面軟水系統的壓試，導致更多勞力的付出，並延誤停爐檢修時間，影響停爐的安全性。And as the charge in the furnace continues to move down, it may cause the original leak to continue to wear and expand, and it may also wear other staves to produce a new leak. That is to say, when the dehydration rate of soft water increases further, it is impossible to distinguish the cause of the existing water system. Therefore, the pressure test of the comprehensive soft water system must be carried out again, resulting in more labor and delaying the maintenance time of the boiler, which affects the safety of the boiler shutdown.

圖1為先前技術之高爐冷卻水密閉循環系統示意圖。請參照圖1所示，高爐冷卻水密閉循環系統設置於一冷卻結構1上，在冷卻結構1最下方的冷卻壁11設置有一入水管12及手動閥121，而最上方的冷卻壁11設有一出水管13及手動閥131。在中間的冷卻壁11則是以金屬軟管14的方式相互串接連通。由於高爐的下部的熱負荷較高，籍由如此的設計讓軟水（SW）由下而上流動，有效地降低高熱負荷區冷卻壁的溫度。Fig. 1 is a schematic diagram of a closed circulation system of blast furnace cooling water in the prior art. Please refer to shown in Figure 1, the blast furnace cooling water closed circulation system is arranged on a
高爐在操作時，必須考慮到冷卻壁11可能會因為爐料磨耗熱面而有漏水的情況，因此會在每一組冷卻壁11之出水管13上設置一壓力錶132，利用關斷入水管12上的手動閥121與出水管13之手動閥131，觀察壓力錶132是否有壓降情況。例如，當壓力錶132之壓力降至接近爐內壓力時，表示該串冷卻壁11水道可能至少一處已磨損漏水，以致與爐內相通，其壓力值才會與爐內壓力相近。When the blast furnace is in operation, it must be taken into account that the
隨著爐內爐料持續下移，可能會造成原破漏處繼續磨耗而擴大，也有可能磨耗其他冷卻壁而產生新的破漏點。意即當SW失水率進一步提高時，對現有的水系統而言，並無法判別是那種情況造成的。因此，必須再進行全面SW水系統的壓試，導致更多勞力的付出，並延誤停爐檢修時間，影響停爐的安全性。As the charge in the furnace continues to move down, it may cause the original leak to continue to wear and expand, and it may also wear other staves to produce a new leak. That is to say, when the SW water loss rate increases further, for the existing water system, it is impossible to distinguish the cause. Therefore, the pressure test of the comprehensive SW water system must be carried out again, resulting in more labor and delaying the maintenance time of the boiler, which affects the safety of the boiler shutdown.

在本發明的一些實施例中，該第一水量計及該第二水量計為一機械式水錶、一電磁式水量計或一流量計其中之一。In some embodiments of the present invention, the first water meter and the second water meter are one of a mechanical water meter, an electromagnetic water meter or a flow meter.

圖4為本發明一實施例之冷卻水切換接管操作方法的操作步驟流程圖，步驟流程如下:Fig. 4 is a flow chart of the operation steps of the cooling water switching pipe operation method according to an embodiment of the present invention, and the steps are as follows:
步驟S410: 同時開啟第一水管組的第一水源入水閥以及第二水管組的第一水源出水閥，使第一水源冷卻水經由入水管注入冷卻結構中後，由出水管循環流通，並注滿冷卻結構。Step S410: Simultaneously open the first water source inlet valve of the first water pipe group and the first water source outlet valve of the second water pipe group, so that the cooling water from the first water source is injected into the cooling structure through the water inlet pipe, circulated through the outlet pipe, and injected full cooling structure.
步驟S420: 當需要切換水源時，關閉第一水源入水閥及第一水源出水閥，使第一水源冷卻水停止注入冷卻結構中；通過將第一水管組的第二水源入水閥以及第二水管組的第二水源出水閥開啟，將第二水源冷卻水注入冷卻結構，完成水源切換。Step S420: When it is necessary to switch the water source, close the first water source inlet valve and the first water source outlet valve, so that the first water source cooling water stops injecting into the cooling structure; The outlet valve of the second water source of the group is opened, and the cooling water of the second water source is injected into the cooling structure to complete the switching of the water source.
在一些實施例中，依據該第一水管組的壓力錶，調整該第二水源出水閥開度，用以改變該冷卻結構中壓力。In some embodiments, according to the pressure gauge of the first water pipe group, the opening of the outlet valve of the second water source is adjusted to change the pressure in the cooling structure.
在一些實施例中，當壓力錶之壓力降至接近爐內壓力時，表示該串冷卻壁水道可能至少一處已磨損漏水，以致與爐內相通，其壓力值才會與爐內壓力相近。In some embodiments, when the pressure of the pressure gauge drops close to the pressure in the furnace, it means that at least one of the stave channels in the series may have been worn and leaked, so that it communicates with the furnace, and its pressure value will be close to the pressure in the furnace.
在一些實施例中，透過壓力錶取得壓力值，並調整該第二水管組之第二水源出水閥，使之略高於爐內壓力0.3～0.5kg/cm2，即可使爐內氣體(為含有一氧化碳有毒氣體）不會從冷卻結構之破漏點倒灌出來，因此將第二水源出水管延伸至開放式的集水槽中就不會有一氧化碳氣體排出，避免造成對人員的危害。In some embodiments, the pressure value is obtained through a pressure gauge, and the outlet valve of the second water source of the second water pipe group is adjusted to make it slightly higher than the pressure in the furnace by 0.3-0.5kg/cm2, so that the gas in the furnace (for Contains poisonous carbon monoxide gas) will not be poured out from the leak point of the cooling structure, so extending the outlet pipe of the second water source to the open sump will not discharge carbon monoxide gas, avoiding harm to personnel.
當現場壓試後找到有漏水的冷卻結構中的該串冷卻壁後，即可將接有破損漏水的冷卻結構中的該串冷卻壁的第一水源入水管與第一水源出水管，透過操作第一水源入水閥、第一水源出水閥關閉後，再將第二水源入水管與第二水源出水管開啟，將軟水封閉循環水切換為間接循環水，將冷卻結構中的該串冷卻壁獨立出來使用間接循環水。按著，只需要持續觀察軟水封閉循環水系統之膨脹水箱水位，若水位不再下降並且走平時，即代表軟水封閉循環水冷卻系統沒有新的破漏點。若膨脹水箱之水位仍然會下降，表示還有另外一處的漏水點，因此需要再進行水道壓試作業，找到破漏點之後再施以本發明之方法切換為間接循環水水源，隔離破漏的冷卻壁。After the on-site pressure test finds the series of staves in the cooling structure with water leakage, the first water source inlet pipe and the first water source outlet pipe of the series of staves in the cooling structure with damaged water leakage can be connected through the operation After the first water source inlet valve and the first water source outlet valve are closed, the second water source inlet pipe and the second water source outlet pipe are opened, and the soft water closed circulation water is switched to indirect circulation water, and the series of cooling walls in the cooling structure are independent Come out to use indirect circulating water. Press, you only need to continue to observe the water level of the expansion tank of the soft water closed circulating water system. If the water level does not drop and is flat, it means that there is no new leak point in the soft water closed circulating water cooling system. If the water level of the expansion tank still drops, it means there is another water leak point, so it is necessary to carry out the waterway pressure test operation, and then apply the method of the present invention to switch to the indirect circulating water source to isolate the leak. cooling wall.
且由於已經將破漏的冷卻壁隔離出來並獨立使用第二水源（間接循環水），藉由調整該第二水源出水管上的第二水源出水閥，讓間接循環水水壓略高於爐內壓力，因此，漏入爐內的水量可以有效地降低。例如，軟水封閉循環水水壓約為5kg/cm 2，破漏處的爐內壓力約為2.4kg/cm 2，切換成間接循環水後，經調整間接循環水回水之水壓至2.5kg/cm 2，經過該第一水量計、該第二水量計的流量值，可以計算得到漏水量，已從0.8M 3/H降至0.25M 3/H，有效降低漏水量。 And since the leaky cooling wall has been isolated and the second water source (indirect circulating water) is used independently, by adjusting the second water source outlet valve on the second water source outlet pipe, the indirect circulating water pressure is slightly higher than that of the furnace Internal pressure, therefore, the amount of water leaking into the furnace can be effectively reduced. For example, the hydraulic pressure of soft water closed circulating water is about 5kg/cm 2 , and the pressure in the furnace at the leak is about 2.4kg/cm 2 . After switching to indirect circulating water, adjust the pressure of the return water of indirect circulating water to 2.5kg /cm 2 , through the flow values of the first water meter and the second water meter, the amount of water leakage can be calculated, which has been reduced from 0.8M 3 /H to 0.25M 3 /H, effectively reducing the amount of water leakage.
綜上所述，本發明的冷卻水切換接管裝置及其操作方法至少具有下列特點：當冷卻結構發生破漏時，透過即時的冷卻水源切換，將已破漏的冷卻元件中由軟水封閉循環系統切換至間接循環水系統，透過對冷卻元件中的壓力值，正確判斷是否還有新的破漏點發生，另外，同時藉由調整的第二水源出水閥的水量進行壓力調節，有效減少漏入高爐內的冷卻水，減緩對高爐爐熱的影響。To sum up, the cooling water switching connection device and its operation method of the present invention have at least the following characteristics: when the cooling structure leaks, through the instant switching of the cooling water source, the leaked cooling element will be closed with soft water in the circulation system Switch to the indirect circulating water system. Through the pressure value in the cooling element, it can be correctly judged whether there is a new leak point. In addition, at the same time, the pressure is adjusted by adjusting the water volume of the second water source outlet valve to effectively reduce the leakage. The cooling water in the blast furnace slows down the impact on the heat of the blast furnace.
