  • Patent number: 9242194
    Abstract: A device (1) comprises filtering means (30) for removing particles from a fluid, which have a particle collecting face (31) for collecting particles during use of the device (1), and a chamber (10) in which a fluid is present and in which the filtering means (30) are arranged. An inlet (11) of the chamber (10) comprises a spouting part (20) which serves for spouting the fluid to be filtered in a direction towards the particle collecting face (31) of the filtering means (30). An arrangement of the spouting part (20) and the particle collecting face (31) with respect to each other is adapted to generate, during operation of the device (1), a rotating flow pattern in the fluid that is present in the chamber (10) under the influence of the flow of the fluid to be filtered, whereby particles can be blown away from the particle collecting face (31).

  • Patent number: 9005340
    Abstract: A fiber bed assembly used to remove aerosols and/or wetted soluble solids from a moving gas stream includes a fiber bed support and a fiber bed supported by the fiber bed support so that the gas stream passes through the fiber bed moving from an upstream space to a downstream space with respect to the fiber bed. A re-entrainment control device is located within a downstream space defined by the fiber bed so that at least a portion of the gas stream passes through the re-entrainment control device. The re-entrainment control device is shaped to change the direction of the average flow path of the gas stream as the gas stream passes through the re-entrainment control device so as to cause aerosols and/or wettable solids contained therein to be separated from the gas stream by inertial force. A re-entrainment control device and method of use are also disclosed.

  • Patent number: 7270690
    Abstract: The separator has a vane assembly made up of a number of corrugated vanes that provide serpentine paths for the gas stream therethrough. As the gas stream flows through the serpentine paths, it changes direction and liquid in the gas stream impacts the surfaces of the vanes. The upstream section of the vane assembly has roughened surfaces to decrease the surface tension of the liquid, thereby causing the liquid to coalesce. The downstream section of the vane assembly has smooth surfaces so as to increase the surface tension of the liquid. The vane assembly is followed by filters, which capture the liquid that passes through the vane assembly. The vane assembly coalesces the liquid to enable the filters to operate more effectively.

  • Patent number: 6858051
    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: 6712884
    Abstract: A particle trap, such as in a honeycomb body, for separating particles out of an exhaust gas flow, includes a flow channel. An exhaust gas flow which includes particles flows through the flow channel. Internals, such as projections, humps, protuberances or the like are situated on one side of the flow channel. An opposite region of a channel wall is completely or partially porous. When a flow of exhaust gas which includes particles flows through the particle trap, the particles are diverted toward the porous channel wall, to which they adhere. They can then be removed again by regeneration. The particle trap and an associated process for separating particles out of an exhaust gas flow, are particularly advantageous when used in the exhaust system of an internal-combustion engine, in particular a diesel engine, specifically and advantageously in combination with a soot filter.

  • Patent number: 6101886
    Abstract: Atmospheric Samplers are disclosed using aerogel filter material. The samplers include one or more cascaded impact sample stations with discs of aerogel as the targets. Ambient air carrying particulate matter is introduced into the sampler and the particles are captured by the aerogel in its pore structure. In certain embodiments, the aerogel filter is next transported to a position where it is fragmented by a spray of water. The fragmented aerogel and the captured particles are transported in the fragmenting water from the sampler for analysis. In one embodiment, the sampler is segmented with alternate nozzle and filter segments for easy assembly, sampling and disassembly for analysis of the captured particles in aerogel filters positions below the nozzles.

  • Patent number: 6099622
    Abstract: An agglomeration and precipitation assembly which includes an agglomeration device in combination with a precipitation device. The agglomeration device is intended to receive a turbulent gas stream containing fine suspended particles and to discharge the stream in which the major part of the fine particles have agglomerated in the form of larger particles. The precipitation device is provided downstream of the agglomeration device to receive the stream coming from the agglomeration device and to separate the larger particles from the gas stream. The fine particles can be separated from a turbulent gas stream by first agglomerating the fine particles in the form of larger particles, and then separating the larger particles by precipitation.

  • Patent number: 5653786
    Abstract: A high capacity marine separator (30) is disclosed which uses a first stage formed by an inertial vane separator (32), a second stage formed by a coalescer stage (36) and a third stage formed by an inertial vane separator (34). The coalescer stage (36) is canted from vertical relative to the air flow direction which increases the surface area for air flow, increases the drainage rate of water from the coalescer section and provides an improved air flow distribution to the second inertial vane separator with higher velocities near the top of the second inertial vane separator. The inertial vane separators (32, 34) have flush cavities to reduce obstruction to air flow and have vanes that are greater than three inches in wavelength and spaced greater than one inch apart. The marine separator is capable of flow velocities of 50 standard feet per second.
