REGULAR NOZZLES FOR THE HEAT-EXCHANGE AND MASS-EXCHANGE APPARATUSES Russian patent published in 2007 - IPC B01J19/32 B01D53/18 

FIELD: chemical industry; petroleum industry; natural gas industry; other industries; production of the nozzles used in the processes of the natural gas rectification, absorption, purification and dehydration.

SUBSTANCE: the invention is pertaining to designs of the regular nozzles, which are used in the processes of the natural gas rectification, absorption, purification and dehydration and also as the mixers of the liquid and gaseous streams as the separators of the phases in the separation devices, as the contact elements in the condensers of mixing, as the sprinklers of the water cooling towers and may find usage practically in all production processes in petroleum, gaseous, chemical and other allied industries. The regular nozzle consists of the corrugated plates gathered in packages installed vertically and in parallel with the inclination of the flutes of the adjacent sheets to the horizon in the opposite sides, contacting by the protruding flutes to each other and forming among themselves the free channels of the complicated geometrical form. The nozzle is supplied with the spacers made in the form of the block of the horizontally laid in the rows in parallel to each another volumetric components. At that the symmetry axes of the components laying in the adjacent in height rows are mutually perpendicular. The ratio of the height of the package consisting of the corrugated sheets to the height of the spacer block lays within the limits of 2-5. The total height of the block of the spacers lays within the limits of 1.0-4.0 equivalent diameters_{of one component. The equivalent diameter of channels of the corrugated sheets package and the equivalent diameter of the component of the block of the spacer are in the ratio of 0.4-0.8. The components of the block of the spacer represent the solids of revolution, which are made in the form of the multiple-thread helicoids, at that the number of the threads makes 2-4. The components of the spacer block are laid in the rows with the clearance to each other, at that the interval, which separates the symmetry axes of the adjacent components makes 1.7-2.5 diameters of one component. The invention allows to raise intensity of the processes of the heat- and mass-exchange due to turbulization of the gas streams and redistribution of the liquid.}

EFFECT: the invention ensures the increased intensity of the heat-exchange and mass-exchange processes due to turbulization of the gas streams and redistribution of the liquid.
