The utility model belongs to the technical field of flue gas desulfurizing tower and particularly relates to an interval-variable inlet flow guiding device of a semidry-process flue gas desulfurizing tower. The interval-variable inlet flow guiding comprises a guide vane fixing frame and a guide vane unit fixed on the guide vane fixing frame. The guide vane unit comprises a plurality of arc-shaped guide vanes which are sequentially arranged in variable intervals according to the arc length from short to long. The interval-variable inlet flow guiding device of the semidry-process flue gas desulfurizing tower is disposed below a flue gas inlet bend, close to a venturi tube, at the bottom of the desulfurizing tower, and is a device with a square section. By arranging the more portable and simpler guide vanes in the guide vane fixing frame, airflow in the desulfurizing tower is controlled to uniformly distribute. The interval-variable flow guiding device is arranged at the upper end of the flue gas inlet bend, airflow distribution in the tower is improved and the problem of treatment difficulty due to the fact that dust falls at the bottom of the tower is avoided.
