摘要： An arrangement for cleaning ventilation air coming from a spray booth (1) for painting e.g. car bodies (2), and polluted with paint particles, comprises means (9) for contacting the ventilation air with a liquid flow for separating part of the paint particles of the ventilation air. At least one wet electrostatic precipitator (6) is provided in an enclosure (7) downstream of said means, for separating the remaining particles as well as liquid droplests contained in the ventilation air and originating from the liquid flow. The enclosure (7) is located underneath the floor (4) of the spray booth (1) and the part of the enclosure (7) which is first contacted by the ventilation air is formed as a sloping plane being poured over with liquid. The lower end of the sloping plane is connected to said means (9) forming a part of said enclosure and being poured over with liquid. The enclosure (7) further is so designed that the ventilation air is caused to be deflected through an angle of 10 DEG -170 DEG in relation to its substantially vertical direction of flow through the spray booth (1) before being caused to pass through the above-mentioned means (9).

摘要： For cleaning flue gas formed on the incineration of refuse, for example domestic refuse, and containing particulate impurities; gaseous organic impurities, such as aromatic chlorine compounds; gaseous inorganic and acidifying impurities, e.g. hydrogen chloride, sulphur dioxide, and nitrogen oxides; and gaseous trace elements, such as heavy metals, the gas is cleaned of its particulate impurities in a separation step (52). Then, the flue gas is cleaned of its gaseous inorganic and acidifying impurities in at least one gas washing step (54a, 54b). Before the separation step (52), the flue gas is brought into contact with one or more substances reacting with the gaseous trace elements and supplied in the form of a dry powder or fine liquid droplets, and/or an adsorption material reacting with the gaseous organic impurities, for transforming the trace elements and the last-mentioned impurities into particulate impurities which are separated from the flue gas in the above-mentioned separation step. The particulate impurities separated in the separation step (2; 22; 52) are heated to such a high temperature that substantially all the organic impurities are decomposed, and that most of the trace elements are evaporated, while the remaining particulate impurities are transformed into vitreous sand by melting.

摘要： A method and an apparatus are used for removing solid, liquid and/or gaseous pollutants from a gas or gas mixture. By means of a gas distributing system (14), the gas is passed below the surface (34) of a bath (32) of washing or cleaning liquid in such a manner that it is caused to rise through the bath (32) in several partial flows, each partial flow having a volume flux independent of the size of the total gas flow. The polluted gas is caused to bubble through the liquid bath at a velocity which is higher than the velocity at which a free bubble rises through the bath. Each partial flow of the polluted gas is completely or almost completely screened off by partitions (48) from adjacent parts of the bath (32). This screening is preferably performed during a substantial part of the passage of the partial flows through the bath (32).

摘要： In a method for controlling the supply and the discharge of hot and/or cold gases to and from, respectively, a tunnel-shaped arrangement (1) for drying and/or cooling vehicles or parts thereof. The tunnel-shaped arrangement is longitudinally divided into a number of sections each of which is provided with a plurality, preferably 60-250, of nozzles (7, 20, 21, 22, 23, 24, 25) which are substantially evenly distributed over the curved inner surface of the section and through which the gases are supplied and blown against the vehicle or the parts thereof passing through the arrangement, the pressure drop of the gases is measured across the nozzles and the temperature of the gases before the nozzles. The measured pressure drop values are then compared with predetermined desired values corresponding to the prevailing temperature, whereupon a pressure increase or a pressure reduction signal is supplied to a first pressure changing means (29) for supplying the gases to the arrangement (1), depending on whether the measured values are below or above the desired values.

摘要： In the cleaning of flue gases formed during the combustion of coal, preferably pulverised coal, the flue gases in a first step are cleaned of particulate pollutants, so-called fly ash, in a first separator (5). In a subsequent step, the flue gases are cleaned of gaseous, acidifying pollutants by mixing the flue gases with a sorbent in the form of a dry powder or fine water droplets in a contact reactor (21). The resulting reaction products are then separated together with unreacted sorbent as a dry powder from the flue gases in a second separator (41). Water is added to the fly ash separated in the first separator (5). The fly ash is then milled in a mill (11) in order to convert the calcium oxide and silicon dioxide present therein into calcium hydroxide and calcium silicates. Also, the fly ash is mixed with burnt or slaked lime and/or silicon dioxide prior to or after milling. The thus treated material is then used as sorbent in the subsequent cleaning step.

摘要： A method and an installation for recovering energy in the thermal destruction of pollutants in a gas emitted from a scrap preheating device (6, 8), e.g. in an electro-steel furnace (1). The polluted gas is conducted through regenerative heat exchangers (12, 15) before or after passing through a combustion chamber (4), for providing heat exchange between the polluted cold gas and the cleaned hot gas. The regenerative heat exchangers (12, 15) are filled with a packing of a material suitable to be charged into the furnace (1) generating the gases which are used in the scrap preheating process, or into another nearby furnace. The packing is withdrawn completely or partly when the performance of a heat exchanger has deteriorated as a result of oxidation or clogging with dust. A new packing is supplied to the heat exchanger concerned, and the packing withdrawn is charged into one of said furnaces.

摘要： In the cleaning of process gases, such as flue gases, containing heavy metals, especially mercury and/or mercury compounds, and possibly also containing acidifying gases, such as hydrogen chloride and/or sulphur dioxide, the process gases are contacted in a contact reactor (6) with an aqueous solution or an aqueous suspension containing a first absorbent material which is reactive with the heavy metals of the process gases and is in the form of one or more metal sulphides, preferably sodium sulphide, for separating the heavy metals from the process gases. The water is then supplied in such an amount and in such a finely divided state that it is completely evaporated when contacting the process gases.
