The invention discloses a demisting device and method for a hot
continuous rolling production line, and belongs to the field of steel rolling. According to the technical scheme, the demisting device of the hot
continuous rolling production line comprises a demisting box, a plurality of pumping and discharging fans are arranged in the demisting box, a suction inlet for forming mist is formed in the bottom of the demisting box in an open mode, a movable mist discharging fan is movably arranged below the suction inlet, the air pumping direction of the movable mist discharging fan is from bottom to top, and the air pumping direction of the movable mist discharging fan is from bottom to top. And the water is discharged into the demisting box. The suction inlet with the open bottom expands the mist adsorption range, the movable mist exhaust fan is matched with the bottom-up air draft direction, the mist generation source can be accurately aligned, mist
diffusion is avoided, the suction and exhaust fan and the movable mist exhaust fan form an up-and-down linkage suction and exhaust structure, the flow guide effect on the mist concentration generation position is enhanced, the demisting efficiency is greatly improved, and the demisting effect is improved. And mist escape is reduced.
