摘要： A method for controlling a ventilating apparatus (11) for ventilation and temperature control of accommodations, e.g. in vessels. The apparatus is connected to at least one ventilation channel (10) and comprises means for volume control of the air flow to the accommodation, means for temperature control of the air flow to the accommodation, and a control unit (13) for controlling the flow and temperature, for adaption to a desired temperature level. The control unit (13) is manipulated for reduction of temperature from a value of origin to a desired value which is at a certain distance from said value of origin. The flow controlling means and the temperature controlling means are adjusted for a rapid reduction of the temperature during a predestinated period of time. After this period of time has lapsed, these means are reset to provide a temperature level which is lower than the original value which existed before the reduction in temperature was started.

摘要： In a process for mechanically cleaning a powder (25), the powder is projected at a predetermined speed and at a determined frequency during a defined time against at least one surface in order to separate therefrom particles of impurities (35) that adhere to its surface. The thus obtained powders (30, 31 and 35) are then sorted according to size. A cleaning device (1) for carrying out the process has a separator (2) mounted upstream of a wind sifter (3) or cyclone (4). A simplified embodiment of the cleaning device (1) has only a wind sifter (3).

摘要： A method and an apparatus for regulating the amount of liquid in the wet cleaning of a gas in at least two stages are disclosed. In the method, liquid from at least one of the stages after the first stage is brought into contact with air, such that the liquid is partly evaporated and cooled, the evaporation being carried out in such a manner that the amount of liquid in the stage remains the same, whereupon the remaining liquid is heated before being recycled to the wet cleaning. The apparatus comprises a scrubber (6) having at least two stages and a liquid-circulation circuit (53) in at least one of the stages after the first stage, the liquid-circulation circuit (53) including an evaporator (20) adapted to evaporate liquid to such an extent that the amount of liquid in the stage remains the same and to cool liquid from the circuit by contacting it with air, as well as a heater (44) adapted to heat the cooled liquid in the circuit.

摘要： In order to create a simple car body surface treatment device, a car body is introduced into and removed again from the treatment bath (11) simply by being rotated by a rotating device (2), at the same time as another car body is pushed onto and secured to said rotating device or conveyed past said device. The car body is fixed to a loading carriage (5) and is pushed by means of some driven rotary rollers (3a) onto the rotating device (2). By means of fastening devices (4a, 4b) the loading carriage (5) is detachably secured to the car body on the rotating device (2). By rotating through 180° around an axis of rotation (7), the rotating device (2) dips together with the car body over its tail or front side into the treatment bath (11). While one car body is submerged, another loading carriage (5) together with a car body fastened thereon may be conveyed by the driven rotary rollers (3b) past the rotating device (2) for subsequent treatment, over the top surface of the rotating device (2).

摘要： A method and an apparatus for cleaning a flue-gas stream containing hydrogen chloride and sulphur dioxide are disclosed. The flue gas is treated in a wet cleaner (5), thereafter injected with lime (9) and filtered through a filter (13). The method and the apparatus are distinguished by the fact that a part of the flue-gas stream is bypassed the wet cleaner (5) through a conduit (15), to join the remainder of the flue-gas stream before the filter (13). In this way, hydrogen chloride in the bypassed stream is reacted with injected lime to form calcium chloride, which promotes the sulphur-dioxide separation upon the injection of lime.

摘要： An apparatus for securing ceramic monolith blocks (17) inside a catalytic reactor chamber (10). The blocks (17) are located upon at least one essentially horizontal, grill shaped support surface (16) between an inlet (12) to the reactor chamber (10) and an outlet (13) from said chamber. The blocks (17) are placed in groups, and pressure means (18) are mounted between the groups, substantially in parallel with the support surface (16), said pressure means acting against the sides of the blocks.

摘要： Method and arrangement for drying of wood by circulating hot air around and through one or more piles (3) of the wood, arranged in batches in one or more closed drying chambers (2 a-f) in a chamber drier (1), the circulating hot air being first caused, in a heating phase, to heat the wood to the starting temperature for drying, subsequently in one or more drying phases accomplishing the actual drying, and finally, in a conditioning phase having a specially adapted air moisture content and air temperature other than during the drying, water vapour being supplied at atmospheric pressure by means (9 a-f), during the heating phase and the conditioning phase, to the hot air circulating around the wood in the drying chamber (1). The water vapour, which is generated in a vapour generator (10) and stored in an accumulator connected thereto, is supplied at a vapour generating capacity of 2-28 kW/m3, preferably 10-15 kW/m3, batch volume of the wood. The vapour generator (10) can be arranged to be supplied, preferably via a hot water conduit (12), with energy from a solid fuel central boiler plant (13) which is adapted to work by burning sawmill refuse, mainly bark.

摘要： A water-spray separator for purifying particle-polluted discharged air (9) from a working area, especially for purifying discharged air containing paint particles from a spray-painting booth, with a flow duct adjacent to the working area and with a cross-sectional extent set by two spaced duct walls (1, 2) into which the polluted discharged air (9) flows and into which a fluid (8) is introduced to run along the channel walls (1, 2). The duct comprises and inlet (1a, 2a), and adjacent expansion section (1c, 2c), an adjacent deflection section (4) which deflects the flow of discharged air transversely to the direction of flow in the inlet (1a, 2a), an adjacent nozzle (5), an adjacent duct outlet (6) in which there is an abrupt narrowing (7) in the duct cross-section, and a reflector section (3) formed on the duct wall opposite the nozzle (5) against the direction of flow through said nozzle and reflecting the noise generated in the region of the nozzle (5) substantially back towards the nozzle (5).

摘要： A method and an apparatus for cleaning sulphur-dioxide-containing gases, such as flue gases, are disclosed. The gases are treated in a gas scrubber (2) for the absorption of sulphur dioxide in an aqueous alkaline washing liquid (3), preferably NaOH. A partial flow (10) is drawn off from the washing liquid to be regenerated by the addition of calcium ions (17) for the precipitation and removal of calcium sulphate. The invention is distinguished by the fact that the precipitated calcium sulphate is recycled and admixed (14) with the partial flow of washing liquid before the addition of calcium ions. The apparatus comprises a gas scrubber (2) having means (5, 6, 7, 9) for circulating the washing liquid (3), a conduit (11) for drawing off a partial flow (10) of washing liquid, a vessel (16) for the addition of calcium ions (17), a vessel (18) for the sedimentation of precipitated calcium sulphate, a vessel (22) for the addition of carbonate ions, a vessel (24) for the sedimentation of calcium carbonate, a conduit (26) for recycling regenerated washing liquid to the gas scrubber (2), and a conduit (25) for recycling precipitated calcium carbonate upstream from the vessel (18) for the sedimentation of calcium sulphate. The apparatus is distinguished by a conduit (19) provided for recycling precipitated calcium sulphate and opening into a vessel (14) which is arranged upstream from the vessel (16) for the addition of calcium ions.
