The high-rate air sampling and particulate collection may be effected with a high-throughput filter cartridge or with a recently developed portable high-throughput liquid-absorption air sampler. Rapid solubilization of lead is achieved by a liquid extractant comprising 0.1-1 M of acetic acid or acetate, preferably at a pH of 5 or less and preferably with inclusion of 1-10% of hydrogen peroxide. Rapid determination of the lead content in the liquid extractant may be effected with a colorimetric or an electroanalytical analyzer.

  • Publication number: 20040040272
    Abstract: With known devices for separating oil in the crank housing ventilator, oil is collected on a refined gas side of a filter, which in operation of an internal combustion engine, often cannot drain off. In this manner, the liquid level increases, so that the filter is increasingly clogged by the oil. Finally, the oil is carried away from a gas stream. In this manner, the oil use of the internal combustion engine greatly increases. With the device of the present invention, the oil collected on the refined gas side is collected in a liquid storage unit (10), whereby the liquid storage unit (10) is protected from the stream, so that the gas stream can not carry away oil any longer. The device includes a support body (9), which is impermeable to the stream by means of a cut-off wall (23), in order to prevent a carrying-off of the oil.

  • Patent number: 6562109
    Abstract: Trap apparatus and method for removing contaminants from the gaseous effluent flows from chemical vapor deposition chambers and processes by flowing the particle laden gas into an upper chamber of the trap apparatus, imparting additional kinetic energy to the powder particles to enhance separation of the powder particles from the gas, and then flowing the gas, sans the powder particles, out of the trap, while the powder particles fall into and are captured by a lower chamber positioned below the upper chamber and remote from the flowing gas. An impeller positioned in the upper chamber in the inlet path imparts the additional kinetic energy. For some reaction gas systems, an optional reactor with hydrophillic, rotating growth substrates enhance and accelerate growth of solid particles, which are then dislodged from the media, and fed by the flowing gas into the upper chamber for capture as previously described.

  • Patent number: 6524373
    Abstract: A method and apparatus for extracting water droplets from a water-laden airstream includes introducing the airstream into an extractor duct, imparting a swirling motion to the airstream at a first axial location in the duct, removing water droplets from the airstream that have been thrown to the inner surface of the duct at a second axial location downstream of the first location, and at a third axial location downstream of the second location removing water droplets not removed at the second location. The water removal mechanism at the second location includes a first collection chamber and a first array of apertures circumferentially positioned about the duct and communicating the interior of the duct with the first collection chamber.

  • Publication number: 20030009998
    Abstract: The invention relates to a bag filter device (12), which device enables collection and draining of particles of liquid from a gas, normally air, flowing through the bag filter (12). Such a bag filter (12) is normally used to trap solid particles from a gas flow, but where particles of liquid, in which there are for example salts or bacteria, are also trapped and possibly permeate the bag filter (12) and drip out on the downstream side thereof. Then the liquid may be carried further in the gas flow and have disadvantageous effect on equipment and surroundings. According to the invention such drawbacks can be avoided or reduced in that the filter material of a lower portion (18) and a bottom portion (19) in the continuation of the lower portion (18) of the bag filter (12) is formed in its entirety or in an outer filter layer (20) by a liquid-tight material. Possibly, the bottom portion (19) is provided with a liquid outlet (39), so that the liquid separated can collect and be drained from the bag filter (12).

    Abstract: A separator for liquid, in particular for removing oil from crankcase gases, having a cover (11) into which a mount (13) for a cylindrical separating cartridge (14) is incorporated. The separating cartridge is composed, for example, of a non-woven separating material (20) wound around a support body (22) having end plates (33) on the end faces (32) of the support body. The end plates (33) may be composed, for example, of a two-component synthetic resin material. This results in a stable component which can be sealed utilizing the elasticity of the end plate (33) when pushed into the mount (13). This results in a cost effective exchangeable part in which several seals are saved in the complete structural component and yields a structural unit having increased economic effectiveness.

  • Patent number: 6398828
    Abstract: A secondary piston compressor has a crankcase, which is provided with a venting device. The latter includes an oil filter, which is constructed in the form of a superfine filter and is arranged in a separate housing. The superfine filter is in communication on the inlet side with an oil filler pipe of the crankcase via a conduit. It is connected on the outlet side to the atmosphere via an active carbon filter. On the inlet side, the superfine filter defines an oil collecting space, which is connected via a conduit to the crankcase with the interposition of a non-return valve. The non-return valve is held in its closed position by the pressure in the crankcase. When the secondary compressor is switched off, it opens and empties the oil collecting space of the superfine filter into the crankcase.
