    Abstract: An apparatus (10) to carry out a process for the in situ generation of agglomerate structures and the controlled influencing of the resulting agglomerates contains a closed flow duct (12) through which is directed an aerosol containing particles (14). For the purpose of the bipolar charging of the aerosol, at least one electrode pair (20, 22) is arranged in the flow duct (12), the electrode (20) being wired, so as to be ungrounded, to the negative pole of a current source, the strength of which is sufficient to produce a corona discharge between the electrodes (20 and 22). The electrodes (20 and 22) of each electrode pair are designed to be needle-shaped and are arranged to be insulated with respect to the flow duct walls, such that their tips (26) are disposed opposite each other. By use of the apparatus (10), it is possible to charge the aerosol which is directed through the flow duct (12) at least virtually symmetrically bipolarly, without any substantial particle deposition in the region of the electrodes (20) and (22) or in the flow duct (12). Thus, specific agglomeration, with regard to at least one of the parameters concentration, structure or dimension, of the particles can be obtained in the flow duct during flow therethrough.

    Abstract: An electrostatic precipitation system (100) utilizes laminar flow of a particulate-laden gas in order to enhance the removal of sub-micron sized particulates. The system incorporates a vertically oriented housing (105) through which the gas flows downwardly therethrough to a lower outlet port (110). The gas, which may be a flue gas enters the laminar flow precipitator (102) through an inlet port (108) for passage through a charging section (104). The charging section (104) imparts a charge to the particulates carried by the flue gas. The flue gas and charged particles then flow to a collecting section (106) which is downstream and below the charging section (104). The collecting section (106) is formed by a plurality of substantially parallel tubular members, each tubular member defining a collecting passage therein. Each tubular member (118) is electrically coupled to a potential that is of opposite polarity to that imparted to the particulates, so as to attract the charged particulates to an inner surface thereof. The collected particulates are subsequently collected in a hopper (112) or reentrained in the gas stream as agglomerates for subsequent removal from the gas by a secondary filter (120), the gas stream then being conveyed to a stack (14) wherein the particulate-free gas can be emitted into the atmosphere.

    Abstract: A gasification system for solid wastes having a thermal reactor and a mechanical gas cleaner, an indirect heat exchange cooler, and an electrostatic precipitator for cleaning and cooling the produced gas. Feed material is continuously fed to he central section of the thermal reactor above an air introduction manifold and nozzles and in an upward direction, forming a stratified charge. As feed material moves upward and outward from the reactor center it is reduced to ash. An agitator assures contact between the hot particulate product and hot gases resulting in gasification of the feed material and net movement to the sidewall of the thermal reactor, forming ash. The air introduction nozzles serve as a grate. Ash descends along the sidewall to the reactor base for removal. The mechanical cleaner has a high speed rotating brush-like gas separator element and scraper combination which removes condensed tars and particulates from the produced gas stream. The device is self cleaning in that condensed tars and particulates agglomerate on the high speed rotating bristle elements and, upon reaching adequate size and mass, are thrown off by centrifugal force to the cylindrical sidewall, where scrapers remove accumulated material which falls to the separator base for removal. An electrostatic precipitator having a cylindrical brush-like electrode suspended from one end by an insulated arm, removes remaining particles or aerosols from the product gas.
