The invention discloses a blast furnace tuyere small sleeve rapid leakage detection device which comprises a blast furnace body, the bottom of the blast furnace body is fixedly connected with a bottom plate, a heat preservation layer is installed in the blast furnace body, a fixing cover is installed at the bottom of one side of the blast furnace body, and one end of a tuyere small sleeve body is located in the blast furnace body and penetrates through the heat preservation layer. The device is simple in structure, avoids the situation that a large amount of water leaks into the furnace, the furnace cools and tapping cannot be carried out, guarantees stable operation of the blast furnace, facilitates improvement of the yield of the blast furnace, is simple and visual in judgment method, avoids misjudgment, achieves timely discovery, timely treatment and accurate judgment, properly controls water inlet and prevents continuous water leakage into the furnace, and is simple and effective in detection method. The detection efficiency is improved, the detection cost is reduced, continuous and reliable use of the tuyere small sleeve body is ensured, the serious accident that the tuyere small sleeve body burns through slag iron in a furnace and sprays out is completely eradicated, and the use safety of equipment is improved.
Description
technical field [0001] The invention relates to the technical field of leak detection equipment for small tuyeres, in particular to a quick leak detection device for small tuyeres of a blast furnace and a method for using the same. Background technique [0002] The small tuyere sleeve is an important equipment in the blast furnace air intake system. It is made of copper, and the cooling water passes through it. It protrudes into the furnace to prevent the hot air and coal powder from directly washing the furnace wall. Its function is to send the hot air into the blast furnace. The front end is a high-temperature environment of nearly 2000 °C, the temperature of the slag-iron melt is above 1400 °C, and the temperature of the hot air passing through the small tuyeres is also around 1250 °C, and the working environment of the small tuyeres is extremely harsh; [0003] As the small blast furnace tuyere is a vulnerable spare part in the blast furnace production, water leakage wil...
