  • Patent number: 8262786
    Abstract: A combustible energy filtering and recycling system includes a filtering tank, a gas exhaust vent, an overflow vent, and a water-collection chamber. A Venturi gas filter pipe is fixed to the filtering tank and connected with a gas intake pipe which is used for introducing a combustible gas into the gas filter pipe. A first end of the gas filter pipe is connected to a water intake pipe, such that the cooling water can be flowed through the gas filter pipe and collected at the water-collection chamber, and thus dusts and impurities in the combustible gas can be submerged into the cooling water due to the effects of pressure accumulation, air acceleration and pressure reboost produced by the gas filter pipe and the inertia effect. The combustible gas insoluble in water will then be introduced into the gas exhaust vent, so that manufacturers can recycle a high-quality and pollution-free combustible gas.

  • Patent number: 7753997
    Abstract: The present invention is directed to a cleaning device for process gases of a reflow soldering system that includes a plurality of cleaning chambers. The plurality of cleaning chambers contain a cleaning liquid for the process gas, where each of the cleaning chambers is adapted to be flown through via a supply line for the contaminated process gas and via a discharge line for the cleaned gas. The cleaning chambers also include a plurality of cleaning walls along which the cleaning liquid is flown for take-up of impurities in the process gas into the cleaning liquid. A plurality of the deposition walls is provided, where at least one of the deposition walls also forms an outer wall of the cleaning device.

  • Publication number: 20100024646
    Abstract: A scrubber has a return air inlet and an outside air inlet receiving contaminated air into a passageway with an aspect ratio greater than 4, the passageway surfaces wetted by a fluid disposed from a pre-wetter. The passageway has a first section whereby contaminated air travels downward toward the fluid surface of a main reservoir, and is thereafter directed upward and through a scrub reservoir having a plurality of apertures. The contaminated air mixes with the fluid of the scrub reservoir, forming a mixture of contaminants and fluid which are returned to the main reservoir, and also producing clean air with airborne fluid droplets which are passed to a demister pad for separating the fluid droplets and returning them to the reservoir, and the cleaned air is provided to a clean air outlet. A blower moves the air through the scrubber, and a pump pressurizes fluid from the main reservoir and provides it to the pre-wetter and to the scrub reservoir, such as through a gutter reservoir.

  • Patent number: 6866705
    Abstract: Sanding and screening are steps in floor finishing that produce large quantities of fine dust which is difficult to remove and which plugs porous filter elements of dust collection systems. Dust collection is enhanced with a floor screening attachment for a floor machine. A vacuum system with a liquid filtering medium is provided to collect dust produced during screening. A dust collection unit is also disclosed to collect and separate sawdust produced by sanding which can cause foaming of a liquid filter medium.

  • Patent number: 6805734
    Abstract: This invention relates to a cascade-type scrubber, with which the wet scrubbing of the exhaust gas and removal of droplets from the gas can be performed in one and the same scrubber, producing a pure, dropless gas. It is thus essential that the cascade tubing typical of the cascade scrubber and the equipment for droplet removal are combined into a single compact entity, which is formed of several nested chambers.

  • Patent number: 6338750
    Abstract: Cleaning apparatus that has at least one suction device that sucks fluid toward the inside of the apparatus and is connected to an external suction duct. Interposed between the duct and the suction device is a device that holds back the solid particles present in the fluid. Such a holding back device includes at least one mixing chamber containing in part the liquid. A further device is provided that causes turbulence in this mixing chamber in such a way as to create a saturated environment of liquid in suspension above a free surface of the liquid contained in the mixing chamber.
