<p>PURPOSE:To widen stable working range as well as raise the efficiency of working of a tray device by providing plural perforated floor plates with plural concavities in the diametral direction of cylinder on a flat surface orthogonal to the longitudinal axial line of an outer shell cylinder. CONSTITUTION:Plural perforated floor plates 1 are provided at given intervals on a flat surface rightangledly traversed by the longitudinal axial line of the outer shell cylinder 4, and the fixed to the cylinder 4 at their contact positions of the wall. The perforated floor plate 1 is provided with the regularly formed concavities 2 and also with the overflow sluice 5, and the holes 3 are also formed at the centers of the concavities 2 of a spherical, columnar, conical, many-sided conical, or trapezoidal form. When operating the device, gas goes up inside the cylinder 4 through the holes 3. whereupon the gas is mixed with liquid staying on the perforated floor plate 1 to effectuate contact, dispersion, or both actions between the substances.</p> |
