  • Publication number: 20150059582
    Abstract: A cascade-type device for intercepting and filtering oil fumes comprises an exhausting space formed between a housing and a filter and a cascading space formed between the filter and an external plate. A wind entrance communicated with the cascading space is formed between a lower portion of the external plate and the housing. The housing accommodates rinsing liquid whose height is higher than a bottom edge of the external plate. A negative pressure formed in the exhausting and the cascading space while drawing air allows the rinsing liquid blown by a wind pressure to hit the filter and generate water bloom for combining oil molecules of oil fumes. When the oil fumes further pass the filter, the oil molecules are adhered to the filter again and then scoured off by the water bloom, thereby attaining a dual-filtering effect and an automatic cleanliness of the filter and the housing.

  • Patent number: 7115155
    Abstract: An air filtration and aromatizer apparatus which includes a housing, a motor in the housing with a fan for drawing air through an inlet toward an outlet through a pollution-collecting chamber, and an elongated hollow tubular perforated member having an upper end connected to the motor output shaft and a lower end disposed in a bath of water. The hollow tubular member is formed in such a manner that as it is rotated by the motor, it draws water from the container under the influence of centrifugal force, and then forces the water through the perforations to form a mist or rain-like atmosphere in the path of motion of the air passing from the housing inlet toward the housing outlet.

  • Patent number: 7014682
    Abstract: An apparatus and process for removing regulated pollutants and other contaminants from a flowing gas stream between a scrubber and an exhaust stack. The apparatus comprises a vessel having a heater chamber, an adsorbent chamber and a filter chamber. The vessel inlet receives the gas stream from the scrubber and the vessel outlet discharges clean gas to the exhaust stack. A heater in the heater chamber heats the incoming gas stream to lower the relative humidity. The gas stream then passes through granular adsorbent material located in the adsorbent chamber to remove contaminants remaining after the wet scrubber. From the adsorbent chamber the gas stream flows into the filter chamber where filters remove entrained particulate matter prior to discharge to the exhaust stack. The process of the present invention includes the above-described steps.

  • Patent number: 6964699
    Abstract: A wet scrubber having a series of chambers for capturing and cooling exhaust gases generated during static test firing of rocket motors. Exhaust gas enters an inlet to a first chamber and is cooled and slowed by a spray solution. HCL gas is condensed and absorbed by the spray solution and precipitates to a liquid slurry at the bottom of the device. The remaining exhaust products enter a demister chamber where nozzles continue to spray the gasses as they pass upward and through a mesh-style demister at the top of the vessel. The demister filters liquid and solid waste particles from the gas stream, and the clean, dry gases are accelerated through a centrifugal fan into the atmosphere. A deflector is positioned within the inlet to the first chamber for containing parts in the event of a motor mal-function.

  • Patent number: 6863716
    Abstract: An air purification system which is well-suited to removing particles from outside air as the air flows into a cleanroom used in the fabrication of semiconductor integrated circuits. A housing provides at least one spray nozzle for spraying fine mist water droplets. In use, the water droplets capture the airborne particles in the air flowing through the housing and adhere to the water droplet target. The water droplets coalesce and form larger droplets which adhere to the surface of the water droplet target and ultimately collect in a drain pan. The low-density water droplet target prevents large pressure differentials from forming in the housing, which pressure differentials may otherwise cause re-vaporization of the water droplets from the target and re-flow of the particles in the flowing air.
