The invention relates to a candle filter element for installation in a pressure vessel or for implementation in a tank or basin open to atmosphere. Main parts of the candle filter element are a fixing device for the connection to the housing, a coupling part to connect the support body with the fixing device, a support body for the filter material with integrated dip channel and a bottom part.

A method for gasifying carbon-containing materials in which the material for gasification and oxygen, usually in the form of air, are supplied to a gas generator where the gasification takes place in a fixed bed reactor. The product gas is drawn off via a product gas line and introduced into a hot gas filter. A filter, preferably provided with filter candles, removes solids such as particles not yet gasified, ash and foreign bodies, while clean gas passes through and is taken off via a clean gas line. An outlet is provided in the bottom region of the hot gas filter to remove residual solids. The hot gas filter is supplied through a line with oxygen, preferably in the form of air, in its middle height region, between the filter bottom and the outlet.

A filter arrangement may include a filter element and a gasket element. The gasket element may include a substantially circular flow-through opening and a locking collar. The locking collar may be arranged along a circumference of the flow-through opening with respect to a circumferential direction. The locking collar may form a hollow cylindrical installation space. The filter element may include a filter element body and a substantially hollow-cylindrical counter locking collar. The counter locking collar may include an open axial side and a covered axial side which may be spaced apart from each other with respect to an axial axis. The covered axial side of the counter locking collar may be covered by said filter element body. The counter locking collar may be at least partially inserted into the hollow cylindrical installation space of the locking collar.

A filter unit is disclosed that increases solids loading capacity, decreases specific flowrate during filtration, and improves backwash effectiveness. A flow shaping plate and/or flow diverting member are used to reduce flow entrance effects during reverse, backwash flow through the filter unit.

A filter assembly including a housing (15) and a filter cartridge (10). The housing has a housing inlet (16) and a housing outlet (17). The filter cartridge (10) has a filter inlet (11) fluidly connected to the housing inlet (16) and a filter element (12) between a top cap (18) and a bottom cap (19). The top cap (18) and the bottom cap (19) create a circular guiding system. The bottom cap (19) has a first part (19a) that receives the filter element (12) and a second part (19b) that is connected with a mating surface (20) of the housing. The second part has a first circular section (21a) and a second section (21b) and the first section has another shape than the second section (21b), such that the bottom cap (19) cannot rotate in relation to the mating surface.

A vacuum formed part includes at least two layers with one layer including a catalyst and the other not including a catalyst. At least one of the layers is formed by applying a slurry to a die or mold and applying a vacuum to the die or mold. The other layer may be formed from a slurry or may be provided onto the die or mold in the form of a fiber mat or blanket.

A dust filtering and collection system for filtering dust and other debris particles from an incoming dust laden air stream, such air stream generally being used for conveying granular material into or from a bulk tank trailer, a railroad car, or other conveying vehicle, the filtering system designed to be functioned by vacuum air pressure, operatively generated by a blower, to draw in the soiled air into the filter system, to cleanse such air for further use in the conveying of the granular material. The air flow may be reversed, to provide for a dislodging of any dust particles from the filtering system, and to cleanse the filter for further efficient usage of the system in conveying granular material into or out of the tank trailer, or other vehicle during usage. The filter system includes a pod of filter tubes encapsulated by a polymer header that mounts to a transverse plate that secures to the approximate upper end of the filter canister of the filtration system.

A set including a filter candle for separating a compressed gas and a disperse phase present therein, and a bottom cap placed on a lower side of the filter candle. The filter candle contains a filter medium containing a coalescence medium for coalescing the disperse phase and a drainage medium for draining the coalesced disperse phase in a downward direction to the bottom cap, where at least one drainage opening is provided in the bottom cap at a position corresponding to the drainage medium for discharging coalesced liquid from the drainage medium. A side of the bottom cap facing away from the filter medium is provided with a drip-off position and with at least one drainage profile which extends from the at least one drainage opening, where the drainage profile is provided for discharging the coalesced disperse phase from the at least one draining opening to the drip-off position.

A device and method of simultaneously removing flammable gases and nitrous oxide are provided. The device includes a thermal oxidation chamber, a high-temperature resistant dust filter, and a catalyst chamber. The thermal oxidation chamber is configured to receive an exhaust gas from a process tool. The exhaust gas includes flammable gases and nitrous oxide. The thermal oxidation chamber has a first exhaust pipe to emit nitrous oxide and dust generated after the exhaust gas is thermally oxidized. The high-temperature resistant dust filter receives dust and nitrous oxide from the first exhaust pipe, wherein the high-temperature resistant dust filter has a filter fiber net and a second exhaust pipe, and the second exhaust pipe is configured to emit nitrous oxide. The catalyst chamber receives nitrous oxide from the second exhaust pipe, wherein the catalyst chamber has a nitrous oxide decomposition catalyst to decompose nitrous oxide into nitrogen and oxygen.

A powder container including a filter that separates air and powder from each other, a hopper that includes a first opening portion installed below the filter, a second opening portion that has an opening area that is smaller than that of the first opening portion, and an inclined surface that partially overlaps the filter in plan view, a container box installed so as to be detachable from the hopper, the container box containing the powder, and a detection sensor (an optical sensor) installed outside the container box so as to oppose a side surface of the container box, the detection sensor being installed near the second opening portion and near a side of the inclined surface in a lower direction.
