摘要： The present invention relates to a method and equipment for recovering heat from exhaust gas removed from an industrial process, such as an electrolysis process for the production of aluminum. Heat is recovered by means of an extraction/suction system, where the exhaust gas contains dust and/or particles. The heat is recovered as the exhaust gas being brought into contact with heat-recovery elements. Flow conditions and the design of the heat recovery elements are such that the deposits of the dust and/or particles on the surfaces stated are kept at a stable, limited level. In preferred embodiments, the heat-recovery elements have a circular or an extended, elliptical cross-section and may be equipped with fins or ribs.

摘要： A raw gas collection system for collecting raw gas from a plurality of aluminium smelting pots is equipped with a plurality of branch ducts, each of which is arranged to channel a respective branch flow of raw gas from an aluminium smelting pot to a collection duct, which is common to and shared by the branch ducts. Each of said branch ducts is, near an outlet thereof, equipped with a curved section for aligning the branch flow with a flow direction of raw gas already present in the common collection duct, and a constriction for accelerating the branch flow through the branch duct outlet into the common collection duct. Furthermore, each of said branch ducts is equipped with a heat exchanger for removing heat from the respective branch flow of raw gas. The combined flow resistance of the constriction and the heat exchanger reduces the need for adjusting the respective branch flows using dampers, thereby reducing the power required to transport the raw gas.

摘要： A raw gas collection system (15) for collecting raw gas from a plurality of aluminium smelting pots (4) is equipped with a plurality of branch ducts (16, 16a-d). Each branch duct (16, 16a-d) is arranged to channel a respective branch flow (32, 32a-b) of raw gas from an aluminium smelting pot (4) to a collecting duct (20a), which is common to and shared by branch ducts (16, 16a-d). Several of the branch ducts (16, 16a-d) are equipped with a combined heat transfer and flow resistance generating element (17) to remove heat from the respective branch flow (32, 32a-b) of raw gas and to balance the flow of raw gas in the raw gas collecting system (15). The combined heat transfer and flow resistance generating elements (17) reduce the need for adjusting the respective branch duct (16, 16a-d) flow volumes using dampers, thereby reducing the power required to transport the raw gas through the system.

摘要： A crust breaking device for metal melts includes a pneumatic cylinder having a cylinder housing, a piston, which is axially displaceable within the cylinder housing, and a piston rod, which is fastened to the piston. The piston rod is guided by the cylinder housing and movable between a retracted final position and an extended final position. The device includes an electronic control unit and a valve arrangement, which can be actuated via the electronic control unit and is connected via control lines to front and rear pressure chambers inside the cylinder housing. The device further includes at least one metal plate that is fixedly arranged within the cylinder housing in order to define a final position of the piston or the piston rod. The metal plate and the piston are electrically connected to the control unit such that a contact of the piston with the metal plate closes a circuit.

摘要： The invention relates to a method for controlling a fume treatment centre (FTC) (23), scrubbing the baking fumes from a rotary baking furnace (1), in which the fumes are drawn in through at least one suction manifold (11) of the baking furnace (1) and collected in a duct (20, 20′) that conveys said fumes to the fume treatment centre (23). The fume treatment centre includes a tower (24) which sprays water into the fumes in order to cool same and a least one reactor (25) for the physico-chemical neutralisation of the fumes, comprising contact with a reagent powder, such as alumina, followed by filtering (36) of the loaded reagent and the fume dust and recycling in the reactor (25) of at least one fraction of the filtered reagent and mixing of the same with fresh reagent. The method includes at least the following steps: the flow of water in the cooling tower (24) is adjusted and/or the flow and/or recycling rate of the reagent in the reactor (25) is adjusted as a function of at least one parameter indicating the level of pollution of the fumes at the inlet of the fume treatment centre (23). The invention can be used for baking carbon cathodes and anodes for aluminium electrolysis.
