| 摘要 |
The invention concerns a high-speed mass transfer tray with contact and separation elements (CSE) with each CSE consisting of an open, vertically aligned nozzle, which rests with its lower end on the tray and displays at least one row of annular holes, in which an axial swirler with two inclined vanes in the upper section and a firmly attached dense net of ribs arranged lengthwise along the nozzle axis at the lower section in the area of the annular holes is located. A cyclone separator located at the outlet end of the nozzle with deflection rings between separator and annular holes, characterized by the fact that the free cross-section of the CSEs for the gas flow measures 0.36 to 0.54 of the pipe cross-section after the swirler to ensure maximum performance of the gas and liquid flow and a high level of mass transfer efficiency, while each CSE between separator and annular holes features at least two deflection rings with a diameter either equal to or slightly larger than the outer diameter of the separator, with weir heights of about 50 to 300 mm above the lower annular holes. The high-speed mass transfer tray is used for processes to separate liquid-gas (vapor) mixtures and for the absorption, rectification, and desorption of mass mixtures, mainly in such fields as the gas, petroleum, petrochemicals, as well as the chemical industry.
