摘要： A method and apparatus for cooling hot particulate material such as cement clinker discharged from a furnace, such as a rotary kiln. A first heat exchanger of the type wherein cooling gas is passed upwardly through the material to cool the material and this gas is heated by the hot material and supplied to the kiln as preheated combustion air. The first heat exchanger is followed by a clinker breaker and a second heat exchanger which includes an arrangement for spraying the hot material with water. The spray cooler is followed by a third heat exchanger of the type wherein cooling air is passed upwardly through the material in direct contact with the material. The cooling air which flows through the third heat exchanger flows directly through the first heat exchanger. A material seal is provided between the second and third heat exchangers to prevent cooling air from passing through the second heat exchanger. A vent from the second heat exchanger is provided to exhaust steam produced when the water contacts the hot material. A control may be provided so that the amount of water sprayed onto the hot material at the second heat exchanger is responsive to the temperature of the material discharged from the third heat exchanger. As a modification, ambient air may be supplied directly to the hottest material discharged from the kiln for passage through the first heat exchanger.

摘要： A pneumatic conveying system for use in conveying solid particulate material such as sand from a source such as a railway hopper car to a vehicle such as a locomotive for use by such vehicle. The system includes a conveyor for transferring the material from the material source to a main storage vessel. A second storage vessel is mounted on an elevated platform and positioned so that the vehicle may pass underneath. A pneumatic conveying system conducts material from the main storage vessel to the second storage vessel. A bubble tube level sensor senses the level of sand in the second storage vessel. When the level of material in the second storage vessel drops below a predetermined point, a control arrangement responsive to the bubble tube level sensor activates a valve on the first storage vessel to permit sand to be admitted to the pneumatic conveying system. When the level in the second storage vessel reaches the predetermined point, the valve on the main storage vessel is closed so that no additional material is admitted to the conveying line. The second storage vessel is an enclosed container having a gas permeable deck dividing the container into a material chamber and an air plenum chamber. Air under pressure is admitted to the plenum chamber to pass through the permeable deck and fluidize the material in the material chamber. Valve controlled conduits extend through the plenum chamber and are flow connected to openings in the gas permeable deck for conducting material out of the material chamber.

摘要： A method and apparatus for removing gaseous fluorides from gases evolved from an aluminum smelting furnace. Basically, the fluorides are removed by achieving intimate contact between finely divided particles of alumina and the fluoride-containing gases. This is achieved by feeding the particles of alumina into a stream of gases collected from the aluminum smelting furnaces countercurrent to the flow of gases. The particles of alumina adsorb the fluorides. The particles of alumina and adsorbed fluorides are then separated in a gas-solids separator, such as a cyclone and the alumina may then be fed to the smelting furnaces. Preferably, two stages are used. The gases supplied to the second or last cyclone in the direction of gas flow are supplied with new alumina countercurrent to the flow of gases. The alumina particles removed in this second cyclone are conveyed to the gas stream supplied to the first cyclone in the direction of gas flow. In a two-stage apparatus, these gases will be those evolved from the smelting furnace. The alumina separated from the first cyclone may be either conveyed to the smelting furnace or recirculated or a portion may be recirculated and a portion conveyed to the smelting furnace. The gases separated in the first cyclone are conveyed to the second cyclone.

摘要： A sealing assembly for sealing the opening between a pair of communicating members such as a rotary kiln and the feed end housing or fire hood of the kiln. The seal comprises a plurality of abradable sealing blocks which are in slight engagement with the rotating member or kiln. These sealing blocks are spring biased toward the kiln and guide means are provided for guiding the blocks radially inwardly toward the kiln as they wear. The ends of the blocks are arranged so that adjacent blocks overlap to insure a continuous seal around the kiln.

摘要： A liquid spray nozzle which includes a pair of concentric tubular members. Liquid to be sprayed is supplied to the outer tubular member and compressed gas is supplied to the inner tubular member. The outer tubular member includes a reducer portion followed by an expander portion. The liquid and gas mix in the reducer portion and the liquid-gas mixture is discharged from the nozzle through the expander portion. The nozzle is particularly designed for use with a gas scrubber and is positioned in the flow path of the gas to be cleaned as it passes from the dirty gas inlet to the clean gas outlet. The liquid spray is countercurrent to the flow of gas to be cleaned.

摘要： A cooler for hot material such as cement clinker which includes a plurality of superimposed heat exchanger sections. Each of the sections includes an arrangement such as a series of alternately fixed and movable grates for moving material from the inlet of the section to the outlet of the section. A material breaker is positioned between the initial heat exchanger section and the second heat exchanger section. A material lock is provided between each section. The material is cooled by air flowing upwardly through the grate and material. Cooling air is introduced into a plenum chamber beneath the last section, flows upwardly through the material in that section and through the material in the succeeding sections and is eventually sent to the furnace as heated combustion air. Before passing through the initial section, water may be sprayed into the air to cool the same.

摘要： Apparatus for blending pulverulent material which employs the technique of fluidizing the material by means of an aerated silo bottom. The silo bottom is divided into quadrants with air under pressure supplied to each quadrant. While each of the quadrants is being aerated, a greater volume of air may be supplied to any one of the quadrants so that the material in that quadrant will spill over onto the adjacent quadrants and the material in the adjacent quadrants will flow into that quadrant to thereby blend the material in the silo. The apparatus employs a novel aeration unit which includes a gas conducting pipe dimensioned to act as a receiver so that the aeration units may be of substantial length.
