Description
Technical Field
The utility model relates to the technical field of blast furnace maintenance, in particular to a device for detecting leakage of a small sleeve of a blast furnace tuyere.
Background
The blast furnace tuyere small sleeve is an important device in a blast furnace air inlet system and has the function of feeding hot air into the blast furnace. The operation of the blast furnace is a very strong continuous operation process, in addition, the tuyere small sleeve needs to work stably and continuously under the environment of high temperature and high pressure, and the working environment is extremely severe, so that the tuyere small sleeve is inevitably damaged and leaked in normal production due to the particularity of the working environment, and meanwhile, if the small sleeve is not timely judged to be damaged and leaked, the leaked water flows into the hearth to influence the heat balance of the hearth, and even the malignant accident of furnace cooling can be caused. Currently, the known tuyere small sleeve leak detection method mainly comprises the following three methods:
1. Direct observation method: when the water mark appears at the tuyere, the blast furnace needs to check each tuyere on site one by a hydraulic worker, then the water inlet valve of the tuyere small sleeve needs to be closed down, and whether the tuyere small sleeve leaks water can be judged by observing whether the air bubble phenomenon exists in the water column from the water outlet of the tuyere small sleeve to the water return groove or not by utilizing the characteristic that high-pressure gas in the furnace enters the water return pipe after the tuyere small sleeve is damaged.
The direct observation method has the following defects and shortcomings that when the water leakage is too small, the direct observation method needs a blast furnace water-viewing tool to prepare quite abundant working experience, otherwise, the bubble phenomenon is not easy to observe in the water column from the small sleeve, and misjudgment is easy to occur.
2. Water temperature difference method: the difference between the water inlet temperature and the water outlet temperature of the small sleeve of the air port is measured, the water temperature difference of the small sleeve of the air port which is not damaged is generally less than 10 ℃, if the small sleeve of the air port is damaged and leaks water to the hearth, the water outlet quantity is reduced, the water outlet temperature is increased, and the temperature difference between the water inlet temperature and the water outlet temperature of the small sleeve of the air port is increased, so that the small sleeve of the air port can be used for judging whether the small sleeve of the air port leaks water or not.
3. Water flow difference method: the difference value of the water flow of the water inlet and the water flow of the water outlet of the tuyere small sleeve is measured, the water flow difference value of the tuyere small sleeve which is not damaged is generally smaller than 0.5m 3/h, if damaged water leakage flows to the hearth, the water yield is reduced, and the water inlet and water outlet flow difference is increased, so that the method can be used for judging whether the tuyere small sleeve leaks or not.
Similarly, the water temperature difference method and the water flow difference method have the following defects that when the water leakage amount is too small, the water temperature difference and the water flow difference of the water inlet and outlet of the small sleeve are not obviously changed, the water leakage phenomenon is not obvious, and the accurate judgment is not possible, so that the treatment and the solution are difficult to formulate, and the stable production of the blast furnace is greatly influenced.
Therefore, a device for small sleeve leakage of the blast furnace tuyere is provided.
