The invention provides an anti-ventilation anti-blocking detection device for a blast furnace hot air duct, which comprises an outer tube and an inner tube, wherein the outer tube is fixed to the shell of the hot air duct and communicated with the shell; the inner tube is fixed to the inside of the outer tube; the lower end of the inner tube is positioned in an embedded hole of a firebrick lining of the hot air duct; and the cavity, which is formed by the inner wall of the outer tube, the outer wall of the inner tube and the outer wall of the firebrick lining, is filled with a sealing medium. The inner tube and outer tube are arranged, and the cavity, which is formed by the inner wall of the outer tube, the outer wall of the inner tube and the outer wall of the firebrick lining, is filled with the sealing medium, thereby avoiding the problems of ventilation and blocking in the blast furnace hot air duct physical parameter detection process.
Description
technical field [0001] The invention relates to a detection device, in particular to a detection device for anti-cross-wind and anti-blockage of a blast furnace hot air pipeline. Background technique [0002] At present, in blast furnace ironmaking production, it is necessary to transmit hot air at a pressure of about 1,300 degrees Celsius and 0.4 MPa through hot air pipes. The hot air pipes are generally constructed of external steel pipes and internal refractory bricks to withstand high temperature and high pressure. In order to measure the pressure in the hot blast pipe, it is necessary to take a pressure hole in the refractory brick lining, and at the same time open a hole in the outer steel pipe and weld the pressure pipe. In this way, the pressure in the hot blast pipe is obtained through the pressure pipe to complete the measurement of the pressure in the hot blast pipe of the blast furnace Measurement; take the same method to complete the measurement of the temperatu...
