Abstract
The invention discloses a combustion air main pipe for a blast-furnace hot blast stove. The combustion air main pipe comprises a main pipe, wherein the main pipe is communicated with a relief pipeline and an air-in pipeline respectively; a relief valve is arranged in the relief pipeline; a regulation valve is arranged in the air-in pipeline; a pressure detection device is arranged on the main pipe and electrically connected with a PLC module; the PLC module is also electrically connected with the regulation valve; and when the pressure in the main pipe is higher than a predetermined value, the pressure detection device transmits the generated level signal to the PLC module, and the PLC module controls to shut down the regulation valve. The problem of energy waste caused by the relief and overflow of some of the combustion air in a relief process of a general combustion air main pipe controlling the pressure in the pipe through the relief of the relief valve is solved.
