    摘要: An apparatus for removing particulates from a gas stream is described comprising a filter (1) through which gas may be caused to flow, at least one first electrode (15) for producing an atmospheric glow discharge located near to but spaced apart from the filter, and at least one second counter electrode (19), the electrodes being connected to an AC voltage supply generating an AC voltage in a frequency within the range of 1 kHz to 200 kHz. A method of removal of particulates from a gas stream comprising causing the gas to flow through such an apparatus is also described.

    摘要: A self-cleaning particle filter for Diesel engines is provided. The filter includes a filter housing, control circuitry, a removable filter sandwich and independent power source. The removable filter sandwich includes a number of sintered metal strips sewn and positioned between two sheets of inorganic material to provide a filter sandwich. Current is delivered to the metal filter strips to efficiently burn off carbon, lube oil and unburned fuel particulates which have been filtered from exhaust gas. The filter sandwich is formed into a cylindrical configuration and mounted onto a perforated metal carrier tube for receiving and filtering exhaust gas.

    摘要: Thin plate-like electric heaters are disposed among multi-layer cylindrical filters for capturing particulates in positions without contacting with the filters. As the means for more reducing the power supply to the heater as the position of the heater is closer to the central cylinder of the multi-layer filters, the thicknesses of the thin plate-like electric heaters or the geometrical patterns of the electric conduction paths are changed to thereby set the resistance values of the heaters in advance in order to reduce the temperature of the central-side cylinder which is apt to be high to thereby realize the balance with the temperature of the outer-circumferential cylinder, or the electric conduction quantity to the heaters is selectively more reduced as the position of the heater is closer to the central cylinder to realize the balance of temperature distribution with the filter on the outer-circumferential side filter.

    摘要: In a filter cartridge for insertion in a housing for the removal of combustible substances from exhaust gases, with a regeneration of the charged filter material by combustion of the substances, the filter consists of a metallic fiber mat welded together so as to form a hollow cylinder which is disposed tightly on an electrically conductive lattice structure. The ends of the hollow filter cylinder are compressed and tightly held, by metal sleeves, in engagement with a cartridge head and a cartridge foot structure and they are welded together by an end face weld seam. Current is supplied to the filter cylinder by way of the cartridge head and foot structure for heating the filter cylinder directly so that the combustible substances collected on the inside of the filter cylinder are efficiently burnt.

    摘要: A particulate trap which can be used in a medium- or small-sized diesel engine car includes concentrically arranged cylindrical filters made of a three-dimensionally reticulated metallic porous material and a plate-shaped electric heater for regeneration having an output of 400 W or less, and is provided between the filters and spaced therefrom. The filters have a relatively shortened length. The heating amount of the filters by the heater is 0.60 W/cm.sup.2 or more. The filter has an increased thickness to make up for reduction in the filter surface area due to the shortened filter length. With this arrangement, it is possible to achieve a high regeneration efficiency with a low-output heater while suppressing heat loss.
