摘要： Fly ash and fine dust in a gas stream from a coal combustor, for example, are efficiently collected in a 2-stage, tubular, granular bed filter. The stages of the filter are arranged one above the other so that the granules may move from the upper stage to the lower stage under the influence of gravity. Larger particulate in the gas stream is first collected by the lower stage, and then the remaining particulate is electrically charged and collected by the upper stage. Both stages are electrified sufficiently to rigidify the granular beds and adhere the particulate to the granules, so that the granules and the collected particulate move downwardly through the filters as a plug. Granules that exit from the lower stage are cleaned and returned to the upper stage. Non-porous granules may be used to prevent fine particulate from becoming embedded in the granules.

摘要： A fluidized bed, particulate collector system wherein, in one embodiment, the bed particles have applied thereto at the surface thereof, an additive that serves to adhere particulate, once collected, to the bed particles. The bed particles and/or additive may be combustible or may be incombustible. In one embodiment, the system includes two fluidized beds, in tandem, the first of which collects particulate mostly in the supermicron sizes and the second of which is an electrofluidized bed that collects particulate mostly in the submicron sizes.

摘要： Method of producing molten glass and system therefor, including providing a glass melting furnace configured to melt a glass sample, the glass sample including glass batch material including soda ash, or cullet or post-consumer cullet, or any combination of batch material, cullet and post-consumer cullet. The method includes introducing glass sample into a chamber of a rotary drum heat exchanger having at least one heat exchange tube; introducing the exhaust gas into the tube; causing a transfer of heat from the exhaust gas in the tube to the glass sample in the chamber to volatilize any organic impurities in the glass sample, heat the glass sample and evaporate water from the glass sample to dry it, the evaporated water forming water vapor in the chamber; contacting the dried sample with the water vapor; and discharging the dried sample from the rotary drum heat exchanger and introducing it into the furnace.

摘要： A method and apparatus is taught for preheating of glass batch materials by direct contact with glass furnace exhaust gases. Furnace gases 15 flow through a batch hopper 1 in horizontal tunnels formed by open bottom tubes 6, with a free surface of batch forming the bottom portion of the tunnel. The tubes are electrically grounded and a high voltage discharge electrode 18 is located axially in each tunnel. The corona discharge from the electrode acts to retain batch and prevent it's entrainment into the flowing gases. Particulate matter from the gases is simultaneously precipitated onto the batch surface. Acidic gas components such as SO2, HCl, and HF are chemically reacted with batch constituents, thereby removing them from the gas stream. Heat is transferred from the gases to the batch by direct contact. Cooled gases 16 exit the hopper, cleaned of pollutants to levels in compliance with strict environmental regulations.

摘要： A method and apparatus for treating cullet before use as a raw material in a glass manufacturing process is disclosed. The method includes providing a bed of cullet; passing hot gases through the bed, the quantity and temperature of gases being sufficient to pyrolyze odor creating impurities within the bed of cullet; entraining volatile products of pyrolysis into gases leaving the moving bed; heating the gases leaving the bed to oxidize odor creating impurities; and discharging the gases to the atmosphere. The apparatus includes a housing containing a moving bed of cullet; a source of hot gases which permits the gases to pass through the moving bed of cullet to pyrolyze odor creating impurities within the cullet and entrain volatile products of pyrolysis into gases leaving the moving bed; and an incinerator to remove odor creating impurities from gases leaving the moving bed.

摘要： Electrified filter bed apparatus includes inner and outer cylindrical bed-retaining structures for confining a granular bed therebetween. The inner cylindrical structure may comprise a cage of superposed frusto-conical louvers and the outer structure may comprise a similar cage or a perforated cylindrical, liquid-drainage sheet. A cylindrical bed electrode for electrically charging the bed granules is suspended between the retaining structures. The tubular bed surrounds an internal gas passage from which polluted gas flows through the bed from the inside out. Gas enters the internal passage from above through an ionizer section of the apparatus. The ionizer section may include a disc-type ionizer assembly in an ionizer tube. The tube may form an extension of the inner louver cage. A corona discharge may be formed between the disc and the ionizer tube by providing electric current to the discs, whereby the corona discharge electrically charges particulate material within the gas stream. The discs may carry radially protruding needles defining circumferential corona discharge points. A blowdown system may be provided for cleaning the ionizer discs and the tube wall in the region of the discs. The apparatus may include means for avoiding blowout of bed granules from between the outer louvers, and a system for washing pollutant-coated bed granules.
