Publication number: 20100319308Abstract: The invention provides an ecologically clean method and apparatus for water harvesting from air. The method is based on changing of thermodynamic state properties of air wind getting a rotation and passing through convergent-divergent nozzles. The apparatus is a water condensation engine exposed to humid wind. The constructive solution has no moving solid parts, and the incoming wind is an inherent moving component of the engine. It comprises a cascade of sequentially arranged horn-tubes and a set of stationary wing-like details. Those horn-tubes transform the wind into a fast and cooled out-flowing air flux coming-and-hitting upon the set of wing-like details, where the air portions are accelerated and eddying. The inner static pressure and temperature decrease in the air portions. The decrease in static pressure and temperature triggers off condensation of water-vapors into water-aerosols.Type: ApplicationFiled: August 11, 2010Publication date: December 23, 2010Inventor: Yuri Abramov

Patent number: 7731770Abstract: A separating apparatus includes a shroud that has a wall having a multiplicity of through-holes. At least one baffle is provided on the inner surface of the wall of the shroud. The baffle directs the airflow entering the shroud towards the central region of the shroud, thereby reducing conflicting air currents. The baffle may also be used to assist correct assembly of the separating apparatus. The baffle may be arranged to locate with a member provided on another component of the separating apparatus, such as a cyclone assembly, in order to locate that assembly in a predetermined orientation.Type: GrantFiled: July 6, 2005Date of Patent: June 8, 2010Assignee: Dyson Technology LimitedInventors: Benjamin John Strutt, Robin Eddington

Publication number: 20100083834Abstract: Fine, solid particles in a gas stream, especially fly ash particles in the hot gas stream from a coal/coke-utilizing synthesis gas unit, are agglomerated by passage through a gas flow matrix element having a body with confined gas flow channels which bring the particles into close proximity to one another in an environment of low turbulence; a rough surface on the gas flow passages provides surface induction to promote agglomeration of the particles. The larger, agglomerated particles may then be removed from the gas stream by inertial separators such as cyclones.Type: ApplicationFiled: September 29, 2009Publication date: April 8, 2010Inventor: Ramesh Varadaraj
