摘要： A method and device for the continuous mixing and removal of pulverous or fragmentary material from a container, such as a silo or the like, so that the various layers of material simultaneously become mixed with each other, in which case material is removed at a level below the feeding level, essentially over the entire silo width, the material being removed so that its sinking rate in the silo increases towards the line between the feeding and the removal points in order to slant the material layers towards the said line so that the material can be removed in a controlled manner from the slanted layers by means of a removal member or members directed across the layers.

摘要： The invention relates to a process for recovering alkali and heat from a black liquor (5) containing silicate from a soda cook of e.g. grass, reed, straw and bagasse. In the process the black liquor (5) is treated with a gas (6) containing carbon dioxide to precipitate silica and lignin, the precipitate (9) is separated (2) from the black liquor, which is evaporated (3) and burnt (4) to generate heat and to recover a sodium carbonate melt. In the invention the black liquor (5) containing silicate is neutralised with a surplus of the gas (6) containing carbon dioxide, which preferably contains over 60% by volume of carbon dioxide. The evaporation (3) of black liquor mainly takes place after the precipitate (9) rich in silica has been separated (2). The combustion is performed with pure oxygen gas or oxygen-enriched air (14), after the black liquor has been brought to a temperature near its boiling point by direct contact with the hot exhaust gases from combustion, all these operations under a substantial over-pressure of at least 100 kPa. With this procedure, a sodium carbonate melt is recovered and a gas (17) containing over 60% by volume of carbon dioxide is formed, which is used to neutralise the black liquor (5) containing silicate.

摘要： The invention relates to an apparatus for heat exchange between two liquids without solid matters contained in the liquids. The apparatus comprises a pressure vessel which is divided into a plurality of compartments, each compartment comprising an inner space having an open end and an outer annular space. A baffle having a closed upper end is provided around the upper portion of each inner space with an annular slit between the baffle and the wall of the inner space. The baffle extends to a level below the upper end of the inner space. Injection nozzles for the heat-receiving liquid are provided in the upper portion of the outer space of each compartment, and an outlet pipe is connected to the lower end of the outer space. Inlet and outlet pipes for the heat-delivering liquid are connected to the upper and lower ends respectively of the inner space. The inner and outer spaces respectively are connected in series, and the heat-delivering and heat-receiving liquids are fed in countercurrent with respect to each other. The heat-delivering liquid generates vapor that passes downwards through the annular slit between the inner space and the baffle and then upwards to meet droplets of the heat-receiving liquid from the nozzles.

摘要： Suspended solid particles are separated from a fluid flow by dividing the flow into partial fluid flows in flow channels having an upper filter surface travelling upstreams and a lower filter surface travelling downstreams, controlling the flow velocity in the channels such that the flow is turbulent but at the same time low enough to allow for sedimentation of the suspended material to form a clear top layer off so that more than half of the liquid fed to the channel is filtered through the upper filter surface, suctioning less than half of the liquid fed into the channel through a sediment formed on the lower filter surface, and finally removing the sediment from the lower surface.
