Blast-furnace tuyere leakage monitoring and alarming system

The invention relates to a blast-furnace tuyere leakage monitoring and alarming system, which belongs to the technical field of the blast furnace monitor, and comprises a blast furnace tuyere cooling water temperature and water flow-rate detection device and a processing module, and on-line monitoring hardware consists of a blast furnace tuyere cooling water temperature detection device and a blast furnace tuyere cooling water flow-rate detection device; the processing module comprises a data collection module, a data validity judging module, a database storage module, a technical calculation module, a tuyere leakage diagnosis module, a manual confirming module, a water stop judging module, a water supply judging module, an image-sound alarming module and a historic record inquiry module; and the processing modules are run on an industrial computer. The blast-furnace tuyere leakage monitoring and alarming system has the advantages that the investment is less, the system is reliable and visualized, objective foundation can be supplied to the leakage situation of the tuyere during the smelting process of the blast furnace, and the blast furnace operator can immediately know the leakage situation of the tuyere and can immediately adopt the effective measures so as to prevent the harm caused by the water leakage on the blast furnace.
