Abstract
A device for dispersing a second phase in a first phase is provided, wherein gas inlet means are arranged at the bottom of a vessel. The outlet parts of these inlet elements have a varying distance to the bottom, this distance decreasing towards the center of the bottom. The distance of the outer outlet parts of the elements to the bottom, for those located near to the periphery, is from 15 to 40% of the diameter of the bottom.
Claims8
A device for dispersing a second phase in a first phase, comprising a vessel containing the first phase having a bottom and inlet means supplying said second phase arranged at the bottom of said vessel, the inlet means including a plurality of inlet pipe elements each rising substantially vertically from said bottom to outlet openings of said inlet means, said pipe element outlet openings having a height over the bottom, and this height decreasing from the periphery of the bottom toward the center of the bottom, such that at least a portion of the first phase flows past outer ones of said inlet elements towards said center to ensure even distribution of the first and second phases over the cross section of the vessel.
A device for dispersing a second phase in a first phase, comprising a vessel containing said first phase having a bottom and inlet means supplying said second phase arranged at the bottom of said vessel for injecting the second phase into the first phase to cause a loop-type motion in the first phase, the inlet means including a plurality of inlet pipe elements each rising substantially vertically from said bottom to outlet openings of said inlet means, said pipe element outlet openings having a height over the bottom of the vessel, this height decreasing from the periphery towards the center of the vessel, such that at least a portion of the first phase flows past outer ones of said inlet elements towards said center to ensure even distribution of the first and second phases over the cross section of the vessel.
