Mobile multi-point measuring device and measuring method for multiphase flow parameters of gas-solid fluidized bed

The invention discloses a measuring method of a mobile multi-point measuring device for multiphase flow parameters of a gas-solid fluidized bed. The measuring method comprises the following steps: determining the measuring range of a probe in horizontal and vertical directions and moving distance during probe measurement; turning a vertical operating panel, so as to shift a probe hole to a lowest position within the measuring range, turning a horizontal operating panel, so as to shift the probe hole to a position on the axis of the fluidized bed, recording displacement reading value, corresponding to the position, on a measuring device, and taking the point as an initial datum point for probe measurement; then, loosening left and right clamping pieces, turning the vertical operating panel, lifting the probe by delta y mm, and turning the horizontal operating panel leftward or rightward by delta x mm, so as to ensure that the coordinate of the probe is (x0+delta x, y0+delta y) and is positioned at a second measuring point; repeating the steps, so as to accomplish the measurement of target parameters of all measuring points within the measuring range. The method has the advantages that the measurement cost is low, the method is accurate in measurement, and a single probe is adopted to perform multi-point measuring of multiphase flow parameters in the gas-solid fluidized bed.
