  • Patent number: 10493390
    Abstract: Provided is an air or gas cleaning blower with a spiral separation chamber. An impeller draws in particulate-pervaded air or gas and imposes a centrifugal force that accelerates the particulate-pervaded air or gas outwards in the chamber. The particulates, because of their heavier mass relative to the air or gas, accumulate against the outer chamber wall. Most of the lighter air or gas is unable to penetrate through the layer of particulates and is trapped in between the particulates about the outer wall and the inner wall of the chamber. The impeller pushes the separated particulates and cleaned air or gas further down the chamber with the particulates ejecting out a first outlet about the outer chamber wall and the cleaned air or gas circulating around the first outlet, moving further down the chamber, and ejecting out a second outlet.

  • Patent number: 9827518
    Abstract: A form of crossflow filtration particle separator which receives a particle laden moving fluid surrounded by a clear moving fluid at a proximal end, and separates the particles into a collection zone, or collector, in response to vortices created by diagonal slits and baffles located from the center of the particle separator to its distal end. The filter operates horizontally in a small amount of space without use of physical filter media or the need of a high pressure flow, while allowing delicate particles to be separated without damage. Particle collection structures allow the separated particles to be carried away in a separate flow.

  • Patent number: 9073062
    Abstract: Methods using vane electrostatic precipitators collect charged and uncharged particles with vane assemblies that are physically arranged to reduce the air flow rate to at or below 1.0 ft/sec (0.305 m/sec). In preferred embodiments, the main entrained air is divided into smaller proportions by using a plurality of vane assemblies in a vane electrostatic precipitator operating at a specific angle that have discharge electrodes in front of the vanes. This results in both the particles being charged and the flow rate of the air and articles being reduced as they traverse between vanes and over the vane surface. The vane width, operating angle, vane length and vane offset are designed to reduce the air flow rate. As a result, at the ends of the vanes, a high percentage of the air flow is less than 1 ft/s.

    Abstract: A proactive steam and mist removal apparatus is employed along a point of application of a rewet or steam shower system to remove excess steam and water droplets to prevent damage to machinery and products. 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: 7374731
    Abstract: A reaction apparatus for producing vapor-grown carbon fibers (VGCF) and a continuous production system for producing VGCF are disclosed. The VGCF reaction apparatus is featured in installing a plurality of holes on the upper portion of inner tubes; and filling thermally conductive material in the areas between the inner tubes and the outer tube. The continuous production system includes the reaction apparatus, a product collection system and a carrier-gas collecting system, wherein carbon fibers produced by the reaction apparatus fall into the product collection system, and in the product collection system, a collection bin full-loaded with carbon fibers is pushed out and an empty bin is pushed into the collection chamber under PLC control as well as atmosphere replacement with inert gas, thereby continuously producing VGCF.

  • Patent number: 7022150
    Abstract: In a centrifugal separator, the rotor of which is adapted to be driven by means of a gaseous driving fluid, the rotor itself supports a ring of turbine blades extending around the rotational axis of the rotor. A stationary nozzle is adapted to direct a flow of the driving fluid towards the ring of turbine members. After the driving fluid has passed between the turbine blades and has influenced them for driving of the centrifugal rotor, it enters a reversing chamber formed by a stationary reversing member. In the reversing chamber the driving fluid is caused to change its direction and is then conducted again towards the ring of turbine members in order to be utilized a second time for driving of the centrifugal rotor.

  • Patent number: 6966934
    Abstract: A gas reclaiming equipment capable of separating SF6 gas from a mixed gas efficiently and shortening reclaiming work under reduced pressure. A gas separation equipment is provided between a gas insulated equipment and a gas liquefaction system. The gas separation equipment separates nitrogen gas from the mixed gas, and concentrates SF6 gas. Only SF6 gas is sent into the gas liquefaction system. The gas separation equipment uses pressure swing adsorption using an adsorbent with selective adsorption. Moreover, a buffer tank for storing mixed gas is provided between the gas separation equipment and the gas insulated equipment. The buffer tank and the gas liquefaction system are connected by a reflux-line. The reflux-line refluxes the gas in a gas phase in the gas liquefaction system to the buffer tank. Furthermore, the gas separation equipment is connected to a storage tank. The storage tank accumulates the nitrogen gas separated with the gas separation equipment.

  • Patent number: 6902593
    Abstract: A multi-cyclone gas/solids separator with reduced solids re-entrainment is disclosed. The separator uses a plurality of cyclones spaced horizontally apart from adjacent cyclones to process flue gas containing residual catalyst fines. Each cyclone has a body that has a feed inlet end for admitting gas and entrained solids into an annular space defined by a sidewall of the cyclone body and a cylindrical gas outlet tube axially aligned with the cyclone body. A solids outlet at an opposing end of the cyclone body has a tangential outlet for solids and a minor amount of gas through a sidewall of the cyclone body. A gas reflux opening is axially aligned with the outlet tube. The plurality of cyclones share both a common catch chamber for solids discharged from the solids outlet, and a common manifold for gas and entrained solids.

  • Patent number: 6869458
    Abstract: A bioclean room is formed surrounded by a frame body with side portions of the frame opened and curtains to be selectively opened and shut to cover opened side portions of the frame body. An air flow passage is equipped with an air cleaning device to deliver the air in the frame body along a top plate to an air blow duct above the patient's head through which clean air is blown into the bioclean room. The frame body is equipped with an opening on the head side of the patient through which a medical console can be received inside the bioclean room when the frame body is brought into abutment against a wall.

  • Publication number: 20030150330
    Abstract: Gas/liquid separating devices include a separator (1) for separating a mixed gas/liquid flow (M). A liquid drain (2) communicates with the separator and defines a liquid storage chamber (30). The liquid drain serves to temporarily store a liquid separated from the mixed flow within the liquid storage chamber, so that a space that is not occupied by the liquid is ensured within the liquid storage chamber. An adjusting mechanism (52, 152) may serve to adjust the pressure within the space of the liquid storage chamber.

  • Patent number: 6478962
    Abstract: The bubble trap is used in extracorporeal blood flow circuits of the type used for open heart surgery. The trap is placed in the external blood flow and it removes small micro bubbles from the blood prior to delivery to the body. The device accelerates the blood flow radially and the small bubbles migrate toward the center of the accelerated flow. These bubbles are concentrated at this location and the blood that contains the micro bubbles is extracted and recirculated before the degassed blood flow is returned to the body.
