The invention discloses a safety prevention and control system for blast furnace gas power generation, and relates to the technical field of gas power generation. The safety prevention and control system comprises a connecting pipe, a pressure detection device arranged on the connecting pipe, a control device and an adjusting device; flanges are fixedly connected to the two ends of the connecting pipe; the control device comprises a detection pipe and a lifting column arranged in the detection pipe, the bottom of the lifting column is fixedly connected with a pressing plate which is in sliding fit with an inner cavity of the detection pipe, and the bottom surface of the pressing plate is fixedly connected with a sealing gasket; and a compression spring sleeving the lifting column is arranged between the top surface of the pressing plate and the bottom surface of the inner wall of the detection pipe. According to the safety prevention and control system for blast furnace gas power generation, through cooperative arrangement of a travel switch, a first travel contact block and a second travel contact block, in the using process of the device, when the gas pressure in the connecting pipe is too large, early warning can be given out, the device can be automatically closed, the danger in the using process is reduced, and the safety of workers is ensured.
Description
technical field [0001] The invention relates to the technical field of gas power generation, in particular to a safety prevention and control system for blast furnace gas power generation. Background technique [0002] Blast furnace gas is a by-product combustible gas in the process of blast furnace ironmaking. Its approximate composition is carbon dioxide, carbon monoxide, hydrogen, nitrogen, hydrocarbons and a small amount of sulfur dioxide. Its dust concentration is 10-50 g / m3 (standard condition), and its average dust production is 50kg / t (pig iron)-75kg. / t (pig iron). The dust particle size is below 500μm, mainly iron, ferrous oxide, aluminum oxide, silicon oxide, magnesium oxide and coke powder. This gas containing combustible carbon monoxide is a low-calorific gas fuel and can be used in metallurgical enterprises. Self-use gas, such as heating hot-rolled steel ingots, preheating ladles, etc. Blast furnace gas can not only be used as heating fuel for steel plants, b...
