    摘要: The present invention provides a poppet damper, disposed in an exhaust gas duct, which makes it possible to perform an easy machining for providing a sealing surface and which provides excellent sealing following deformation caused by heat. The poppet damper includes a damper seat, disposed in a duct casing; a poppet plate for controlling exhaust gas flow by adjustment of a gap between the poppet plate and the damper seat; and an air cylinder and a damper shaft for allowing driving of the aforementioned poppet plate in a reciprocating manner. A seal plate is mounted to the poppet plate (3), which seal plate is separated by a gap of predetermined size from the poppet plate, with the seal plate placed in contact with the damper seat when the damper is closed.

    摘要: In a method for separating heavy particles from a particulate material containing such heavy particles, use is made of a device having a Coanda sifter, which is adapted to receive a flow of the particulate material and which has a downwardly-facing, convexly single-curved surface (9), and a zigzag sifter (13) arranged after the Coanda sifter and having a plurality of zig-zag-shaped vertical walls (14) which are perpendicular to the axis of curvature of the single-curved surface (9) and define between them channels (15) extending upwards in zig-zag fashion. The particulate material is transported to the Coanda sifter and is conducted over its convexly single-curved surface (9) to have imparted to it a direction of motion (P1, P2) which is dependent on the weight of the particles and in which the particles are guided into the zigzag sifter (13). The particles are guided into the channels (15) of the zigzag sifter (13) in the lower portions thereof and from the side parallel to the channel walls (14). The particles are transported up through the channels (15) with the aid of a flow of transport air which is so adjusted that the heavy particles are separated in the zigzag sifter. (13).

    摘要: A device is arranged in the drying section of a papermaking machine for reducing the effects of the tendency of a paper web (4) to adhere to a drying cylinder (1) as it passes from the drying cylinder to a subsequent guide roll (2). In the drying section, the paper web (4), supported by a drying fabric (5), is conducted alternatingly over a plurality of drying cylinders (1) and guide rolls (2). A blow box (6) is arranged in the transition portion (A) and has a wall (7) extending in parallel with the drying fabric (5) so as to form a narrow air gap (8) between the wall and the drying fabric. The blow box (6) comprises nozzle (12) having a slot-shaped opening for ejecting a well-defined air jet (P1) towards the drying fabric (5) away from the air gap (8). The nozzle (12) is directed such that its center plane intersects the circumferential surface of the drying cylinder (1) along a first straight line positioned upstream of a second line, along which the paper web (4) leaves the drying cylinder (1).

The mixing space (51) is defined downstream by a wall (35) having a plurality of second holes (39). An inlet device (11a, 11b, 11c) comprising the inlet (31b) for compressed gas and the inlet (32b) for liquid consists of two concentric tubes (31, 32). The inlet (32b) for liquid consists of the inner tube (32). The inlet (31b) for compressed gas consists of the annular conduit (31b) between the concentric tubes (31, 32). The inner tube (32) is closed in the axial direction downstream of the first holes (38) provided for introducing the liquid into the mixing space (51). A convergent channel (57) connects the mixing space (51) to the outlet (41).

    摘要: A method and an apparatus for cleaning a gas containing pollutants, such as hydrogen chloride and heavy metals, are described. The polluted gas (2) is contacted with an aqueous washing liquid (3) in a scrubber (1), whereupon part of the washing liquid is preevaporated in a preevaporation unit (7) to form a hydrochloric-acid-containing top fraction, which is essentially free from heavy metals, and a bottom fraction containing hydrochloric acid and heavy metals. Part of the bottom fraction is recirculated (15) for renewed preevaporation, while the remainder of the bottom fraction is treated (16) to remove any heavy metals present. The top fraction from the preevaporation is distilled in a rectification unit (22) to form a top fraction (31) and a bottom fraction (35).

    摘要: The treatment, through a dry adsorption process, of a gas from a hot electrolytic process for aluminum production comprises at least two stages. Particulate aluminum oxide (the adsorbent) passes through the stages of the adsorption process countercurrently to the gas. Thus, the gas is treated with a partly spent adsorbent in a first dry adsorption stage, whereupon the particulate adsorbent is separated from the gas downstream from the first adsorption stage. Part of the separated particulate adsorbent is removed from the adsorption process for recycling adsorbed fluorine-containing substances to the electrolytic process. The remainder of the separated adsorbent is recirculated in the first adsorption stage in order to optimize the adsorption of fluorine-containing substances and the desorption of sulfur dioxide from the aluminum oxide in this stage. Simultaneously, the gas is transferred to a second dry adsorption stage. In this second stage, the gas is treated with essentially unspent, reactive particulate aluminum oxide, so that any gaseous fluoride remaining in the gas is very efficiently adsorbed, while at the same time a substantial part of the sulfur dioxide in the gas is also adsorbed. Finally, this particulate aluminum oxide is separated from the gas downstream from the second dry adsorption stage, before the gas is discharged into the surrounding atmosphere. The separated aluminum oxide is transferred to the first adsorption stage, optionally after passing a desorption stage for the removal of the adsorbed sulfur dioxide in order to reduce the discharges of sulfur dioxide from the aluminum production. The separation of sulphur dioxide in the second adsorption stage is improved by recycling, to the second adsorption stage, aluminum oxide having undergone the desorption treatment.
