Abstract
An airflow separator of the present invention includes: a first column into which gas is introduced from a lower portion and inside which a sample is made to flow; a heavy particle recovery device provided at the lower portion of the first column; and a control device configured to control a wind speed by an amount of gas to be introduced into the first column. The first column has a weak rotational airflow generation mechanism to smooth wind speed distribution in a cross-section of a tube of the first column by making it substantially W-shaped from a portion of a wall of the tube to the center of the tube to another portion of the wall of the tube. The heavy particle recovery device recovers from the sample, heavy particles falling down. The airflow separator recovers emission gas, intermediate and light particles from an upper portion of the first column.
