  • Patent number: 8357232
    Abstract: The present invention relates to a system and method for the separation of gaseous components from gaseous mixtures in order to control emissions and treatment of the gaseous components. In one embodiment, the system makes use of a fan or gas moving device to first impose centrifugal forces on gas streams as the gas moves from the center of the fan toward the periphery of the fan housing. Heavier gases are forced to the outer regions of the fan housing while lighter gases remain closer to the fan axis. The heavier gases and lighter gases exiting the fan housing flow into a duct at different flow rates, and the heavier gases are diverted from the larger volume gas streams and then processed.

  • Patent number: 8147581
    Abstract: A separation housing houses a rotor with multiple suspension chambers. Each chamber has a radially extending web portion between two rotating discs. An orifice is provided through the radially extending web portion. Another web portion urges gas radially out of the rotor. Passages through the rotating disks permit entry of gas and solid particle mixtures into the suspension chambers at high speed traveling toward each other in a suspension adjacent to the orifice. The web portion that urges gas out of the chamber pulls gas away from the suspension zone. Gas moving through the aperture and into a clean gas chamber pulls gas in the opposite direction. The result is gas in the suspension zone being fixed relative to the rotor or changing direction. Centrifugal force moves solid particles radially out of the chamber.

  • Patent number: 7927395
    Abstract: The invention relates to a centrifugal separator for cleaning of gas from solid or liquid particles suspended therein which are of greater density than the gas. A main object of the present invention is to accomplish a centrifugal separator which does not have said inactive regions and thereby achieves efficient separation of particulate contaminants from a gas. This object is achieved by the centrifugal separator initially defined, which is characterised in that the interspaces between the separation discs at least at their radially outer parts are substantially open for flow of the gas in the circumferential direction and that mutually adjacent separation discs are arranged at mutual spacing such that rotation of the rotor causes a pumping action in the interspaces, which pumping action drives the gas from the gas inlet, through the interspaces between the separation discs and out via the gas outlet.

  • Patent number: 5837019
    Abstract: For the purpose of separating dust particles inside a cooling system of a rotor, fitted with moving blades, of a turbo-machine, a device is arranged upstream of the moving blades to be cooled and in the region of the rotor outer surface. The device has at least one feed channel through which a coolant flows, and is directed in the radial direction such that the dust particles located in the coolant accumulate on the side accelerating in the direction of rotation of the rotor. These dust particles subsequently pass into a separation chamber operationally connected to the feed channel and in which they are captured in order then to be discharged.

  • Patent number: 5766315
    Abstract: An air precleaner and method for centrifugally ejecting heavier-than-air particulate debris from an air stream utilizes a circular separator chamber formed with a toroidal dome for smooth airflow transition of the vortex airflow moving through the separator chamber in a cyclonic pattern upwardly from an inlet in a base of the precleaner past a debris ejection duct where it is folded over by the toroidal dome for whirlpooling down to an outlet in the base radially inwardly of and through the upwardly moving vortex airflow. The area for the airflow in the separator chamber progressively decreases linearly to increase the speed of the airflow in the chamber. A particle accelerator assembly includes a plurality of appendages that arc back from a central hub in a swept-back attitude relative to a direction of the vortex airflow.

  • Patent number: 5713972
    Abstract: A Particulate Matter Filtration System, finding application for the filtration of particulate matter which is present in the combustion exhaust gases of internal combustion engines in general, manufacturing processes resulting in the generation of industrial factory exhaust, coal, wood or oil fired furnaces and the like and all particulate laden gas streams. The system comprises a rotating filter assembly comprised of a plurality of materials suitable for the filtration of such particulate matter from all particulate laden gas streams and is of sufficient volumetric construction in order to provide the proper filtering and flow with respect to the volume of gases generated by a particular application, an outer shell enclosure providing a radial boundary to confine the particles, a collector for the particles to come to rest in, and having a drive to provide the necessary rotational speed to provide aerodynamic and centrifugal forces.

  • Patent number: 5554343
    Abstract: A fluid centrifuge device for separating fluids and/or solids comprises a non-rotatable containment vessel (6) and a rotatable shroud (6A) of conical or other form within said vessel (6). The vessel (6) is located between an inlet assembly (2) including a manifold (8) which leads to the interior of a tubing housing (14) of a turbocharger and an outlet assembly (4) including two outlets (10, 10A) for respectively clean and dirty gases. The shroud (6A) is mounted on a drive shaft (20) for rotation therewithin. The shaft (20) and the shroud (6A) are driven by turbine blades (16) or by other drive.

  • Patent number: 5505756
    Abstract: A ramp outlet air precleaner has a base assembly, a dome shaped hood, and a rotor assembly. The base assembly includes an inner circumferential wall and an outer circumferential wall, the inner circumferential wall defining an air outlet port. Angled web supports connect the outer circumferential wall to the inner circumferential wall and the arrangement forms air inlet ports that direct air upon the rotor assembly. A ramp extends perpendicularly and axially from the outer circumferential wall and, starting at the top of the outer circumferential wall, the ramp surface winds around the outer circumferential wall in a spiral, terminating near the bottom of the outer circumferential wall below its starting point. The two ends of the ramp form the top and bottom of a particulate discharge port gap. The rotor assembly includes a hub that has arms extending outwardly therefrom.

  • Patent number: 5092912
    Abstract: The invention is an air pollution abatement system which embodies four different phases. The phases are: the primary impinger section, which removes most of the contaminants by variable density rotational impingement combined with a degreasing solution; the turbo impinger section, which extracts the residual moisture and aerosols introduced within the primary impinger section; the deluge/saturator section, which scrubs the gas with water or chemicals and finally the dehydrator section which hydroextracts the moisture and introduces static electricity to trap any residual micron-sized particulates prior to exhaustion into the atmosphere. The system, while operating, is continuously self-cleaned and computer system managed.

  • Patent number: 5050508
    Abstract: An improved system is provided for the incineration of refuse, especially scrapped automobile and truck tires and the treatment of incineration exhaust gasses as produced thereby. The refuse is incinerated in a closed fire box at controlled temperatures with the incineration exhaust gasses being serially treated by filtration, after-burning, washing with water by use of both a water bath and a water spray, washing with a petroleum based solvent, and cooling to a temperature below the freezing point of water. Filtration is carried out by a self-cleaning apparatus. A combined apparatus is used to carry out both the water bath and water spray with the resultant gasses being acceptable for release into the atmosphere.
