Process of Electrostatic Recirculation for Dedusting and Gas Cleaning and Device Thereof

Номер: US20120067214A1
Автор: Romualdo Luis Ribera Salcedo
Принадлежит: Individual

Cyclones with electrostatically enhanced recirculation, comprising a collector cyclone and an entry for dirty gases, located upstream from a recirculator and a central exhaust channel (CEC) for exhausting cleaned gases. Cyclones are placed in series and have a recirculation line from the concentrator to the collector to recirculate part of the gas stream. Recirculator has means for applying a high voltage producing an ionizing electric field driving particles away from CEC, without significant particle deposition on recirculator walls. Current density in the recirculator field is below 0.1 mA/m. 2 Average electric field is below 2×I0 5 V/m. Particles are driven away from CEC in the recirculator by joint action of mechanical/electrical forces, the latter deriving from particles traversing the ionized field, concentrating them in the fraction of gas stream recycled back to the collector cyclone, where a part is captured. Uses include dedusting, dry gas cleaning (for acid gases), and capturing bacteria.

A dual stage filter assembly for use in a fluid cleaning and sludge removal operation. An upper stage centrifugal separator incorporated into a first vessel. A lower stage baffle filter is incorporated into a second vessel, such that a dirty fluid flow delivered to the upper stage separator includes a clean outlet along with a separate dirty outlet which is delivered to an inlet of the lower stage filter for subsequent filtering and outflow. A convex collection element facilitates delivery of dirty fluid to the lower stage filter and includes a cone shaped separator element and can be either fixed or removable relative to the upper stage separator. An ascending pipe from the upper separator evacuates a clean fluid flow resulting from a negative pressure created within the upper separator concurrent with the dirty outlet from the upper stage being directed through the baffle filter in the lower stage.

Provided is a chiller and system that may be utilized in a supercritical fluid chromatography method, wherein a non-polar solvent may replace a portion or all of a polar solvent for the purpose of separating or extracting desired sample molecules from a combined sample/solvent stream. The system may reduce the amount of polar solvent necessary for chromatographic separation and/or extraction of desired samples. The system may incorporate a supercritical fluid chiller, a supercritical fluid pressure-equalizing vessel and a supercritical fluid cyclonic separator. The supercritical fluid chiller allows for efficient and consistent pumping of liquid-phase gases employing off-the-shelf HPLC pumps. The pressure equalizing vessel allows the use of off-the-shelf HPLC column cartridges. The system may further incorporate the use of one or more disposable cartridges containing silica gel or other suitable medium. The system may also utilize an open loop cooling circuit using fluids with a positive Joule-Thomson coefficient.

Swirl helical elements for a viscous impingement particle collection and hydraulic removal system

Номер: US20150040762A1
Автор: Fred J. Mueller
Принадлежит: MUELLER ENVIRONMENTAL DESIGNS Inc

A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element, and in a toroidal vortex ring created in the annular space. The area and geometry of the helical path, the conical cavity, and the inner and outer tubes is optimized to provide efficient separation at varying gas flow rates and at varying liquid loads.

A method and apparatus for filtering fuel in a motor vehicle includes a cyclonic fuel filter, the cyclonic filter including a housing having a body forming a cyclone chamber defined by walls of the body. The body includes an inlet to receive fuel and an outlet to transport fuel away from the cyclonic fuel filter after it has been processed. The cyclonic fuel filter further includes a receptacle to receive particulates filtered from the fuel. Fuel introduced into the inlet, travels along the inner wall in a cyclical circular pattern, subjecting it to centrifugal forces as it rotates. The centrifugal forces cause heavier particulates to travel outward against the walls of the cyclonic fuel filter, and the force of gravity causes those particulates to move down the wall to be received within the receptacle at the bottom of the cyclonic filter. Filtered fuel exits through an outlet at the top of the body of the cyclonic filter. 1. An in tank fuel sending unit comprising:a cyclonic filter assembly adapted to be positioned in a fuel tank of a vehicle, the cyclonic filter assembly including a cyclonic chamber, having an inlet opening adapted to receive unfiltered fuel, an outlet, and a particulate storage chamber, the particulate storage chamber and outlet opening being axially aligned about a first axis;an exit passageway connected to the outlet to receive filtered fuel;wherein the inlet opening is connected to an inlet port to transport unfiltered fuel from the inlet port into the cyclonic chamber, the cyclonic chamber including a conical portion having a first diameter adjacent the storage chamber and a second diameter positioned closer to the inlet opening, the second diameter being greater than the first diameter;a fuel pump positioned downstream from the cyclonic filter and a fuel reservoir that houses at least a portion of the fuel pump and cyclonic filter.2.

No invention or process on record combines heat and vacuum to remove water , alcohol and other moisture from used oil.2. No invention or process on record combines heat and pressure to filter oil to the level of one micron creating usable recycled oil while retaining additive packages in the oil.3. No invention or process on record removes particulates that are less than one micron through the use of a centrifugal clarifier. NoneThere has been no federally sponsored research and development related to this invention.There are no parties related to a joint research agreement.There are no sequence listings relating to this invention.There are no prior disclosures related to this invention.The seed for the development of the invention was planted more than seven years ago by the applicant, Robert R. Norwood. Mr. Norwood, at the time, was consulting with a top fuel drag race team and determined that the team would be better served by recycling the engine oil from their race cars rather than replacing the oil in the engine following each pass down the drag stripThe invention is a device, contained within a cabinet-sized unit that recycles oil drained from engines and machinery of all types. The used, dirty oil from the engine or machinery is cleaned and filtered down to a particle size of one micron by the unit. The cleaned oil can be re-used in the very engine or machinery out of which it was drained, allowing the oil to be employed over and over for the life of the engine or machinery. A formerly discarded material is now recycled, promoting sustainability by eliminating an end-of-life event for millions of gallons of engine oil annually. The Steamin Deamon is assembled from a ...
