    Abstract: In embodiments, an air filter apparatus includes a base structure (210), an air propulsion mechanism (220), and an adhesive air filter (ADAF) (240) that has an adhesive surface (242). The air propulsion mechanism may establish an air flow (252, 254, 256, 258). The base structure may be configured such that the air flow goes past a vicinity (222) of the adhesive air filter (240), and at least some of the particulates (262, 264) in the flowing air impact the adhesive surface (242), and thus become adhered to it and captured by it. The adhesive air filter could be made from commercially available adhesive tape that is discarded when saturated. Since it is impervious to air, small particulates can be captured upon impact economically. Embodiments may purify the air in enclosed spaces such as homes, offices, and passenger compartments, preventing health problems. Embodiments may further reduce pollution from chimneys.

    Abstract: In this process, a gas stream containing the oil to be separated is circulated between an inlet zone and an outlet zone, and a calm vacuum zone is created where the oil is recovered and evacuated, after having been captured. According to the invention, the gas stream is passed in contact with a porous media, one face of which is in contact with the calm vacuum zone. The drops of oil are thus captured by the porous media and sucked through this media to arrive in the calm zone. This process is applicable to decanters of oil at impacters and also to cyclone separators, in particular in the automotive field.

  • Patent number: 8535402
    Abstract: A particle reduction system and method is disclosed having an air stream accelerator, a feeder assembly, a variable speed wheel lock operably associated with the feeder assembly for releasing raw material into a conveying air stream created by the positive displacement pump, and a particle conditioning assembly. The raw material is carried by the conveying air stream through the particle conditioning assembly, where particle of the material are collided with each other for the purpose of reducing the size of the particles. In some embodiments, a non-thermal drying system can be used to extract moisture from the raw material. The moisture/solids separation occurs, in large part, due to a head-on collision of two conveying air streams. The collision creates a large squeezing force, much higher than a centrifuge or filter. This impact squeezing acts to squeeze the moisture out of the raw material.

The apparatus includes an internal chamber equipped with cooled baffles that promote condensation and a condensate collection mechanism. A vacuum source draws a stream of ambient steam and water droplets from the environment along a path into the chamber and a projected gas stream directs the stream into the chamber wherein at least a portion of the ambient steam condenses into condensate. The remaining portion of ambient steam is separated into water and cold air that is recycled as the projected gas. Steam and moisture that escape capture into the internal chamber are heated by a hot air blower that raises their relatively humidity so that the dried air dissipates harmlessly into the atmosphere.

  • Patent number: 7824457
    Abstract: A portable dust collector for woodshop or other use with portable tools has a conic body that is supported on a tripod carriage formed of three legs attaching to gussets at the sides of the conic body. A divider plate within the conic body divides it into a cyclonic chamber between the divider plate and the lower nose, and a fan chamber between the divider plate and a motor plate that closes the upper mouth of the conic body. A final filter cartridge is fitted onto the outlet pipe, so that the dust collector exhausts clean, filtered air into the ambient. The final filter may be supported from a 90-degree elbow, with a removable tray for catching process dust that is knocked off the interior of the filter. The process dust in the cyclone settles into a dust collection barrel supported on a barrel cradle.

  • Patent number: 7497897
    Abstract: An air supply device for the passenger cell of a motor vehicle includes a rotating element formed in an axial suction intake region of the air-conditioning blower and upstream of the air-conditioning blower. The rotating element covers the air inlet region such that all the sucked-in drops impinge onto the element. Arranged in front of the housing wall of the air supply device are drop interception elements which are fixed lamellae of low inclination or wedge structures with acute wedge angles. The drop interception elements are inclined so that the drops impinge at an acute angle. Active water and particle (pre)-separation is thereby ensured.

  • Patent number: 7452409
    Abstract: A powered air cleaning system (31) and air cleaning method are disclosed. The system comprises a flow path (22) extending through the system from an air inlet (4) to a clean air outlet (5). A motor-driven fan (24) located along the flow path draws particulate debris laden air into the inlet and rotates it about an axis (A-A) to form a rotating flow that stratifies the debris laden air with the heaviest particles in the outermost orbits of the rotating flow. An ejector port (33) is provided for ejecting particulate debris laden air from the stratified rotating flow in the system to the environment. An air filter (9) located within the rotating flow and across the flow path upstream of the outlet filters air from the innermost orbits of the stratified rotating flow.

  • Patent number: 7387653
    Abstract: An assembly for cleaning particulates from fluid streams has a primary and secondary centrifuge collectors and may employ negative pressure to produce the fluid stream. The primary centrifuge collector forms an outer vortex to remove larger particles, then an inner vortex to produce higher centrifugal forces upon and to remove a portion of the particulates. In the secondary centrifuge collector, a plurality of secondary centrifuge collector units are present. The partially cleaned fluid stream enters one of the secondary centrifuge collector units, where swirl vanes form an outer vortex. The fluid flow travels along the secondary vortex to the bottom of the secondary centrifuge collector unit, where the direction of the fluid flow is reversed and the fluid flow is subjected to a higher energy inner vortex. The centrifugal forces exerted by these vortices convey the particulates to the walls of the secondary centrifuge units, where the particulates are evacuated initially by gravity for disposal.
