摘要： An air pollution control system incorporating a venturi scrubber and a method of cleansing a particulate-laden, contaminated gas flow are disclosed. Spray nozzles are used to introduce optimized droplets of a scrubbing liquid into the venturi to maximize the collection efficiency for optically active particles. The spray nozzles introduce the optimized droplets substantially upstream of the throat of the venturi such that the spray mixes with the effluent gas flow and cools the gas flow to substantially its saturation temperature prior to entering the venturi throat. This promotes collection of condensibles and inhibits the revolatilization of contaminants that are collected by the scrubbing droplets which might otherwise evaporate in the hot gas flow. The optimized droplets are highly effective in rapidly cooling the effluent gas flow.

摘要： An air pollution control system incorporating a venturi scrubber and a method of cleansing a particulate-laden, contaminated gas flow are disclosed. Spray nozzles are used to introduce optimized droplets of a scrubbing liquid into the venturi to maximize particle collection efficiency. Due to the very small size of the spray droplets they absorb gases in quantities in excess of the amount predicted by Henry's law. After passing through the venturi the spray droplets are reconsolidated and flow to an enclosed container. Due to the applicability of Henry's law to the relatively large reconsolidated volume of scrubbing liquid, the liquid is naturally effervescent. Bubbles formed in the liquid volume cause suspended particles in the liquid to rise to the surface where they form an easily collected surface scum. The effervescent gases, at least some of which may be noxious, are then incinerated or otherwise treated. In a further aspect, the present invention discloses automatic control systems which adjust the venturi as the properties of the effluent gases change. For example, in one embodiment, the spray volume and/or droplet size is adjusted as the particle concentration changes. In another embodiment, the spray volume is increased as the volume of effluent gas decreases.

摘要： A venturi scrubber for cleansing a contaminated gas flow is disclosed. An optimized spray of liquid droplets are injected into the gas flow from one or more nozzles positioned within the throat of each venturi element. The spray is injected counter to the direction of gas flow to increase interactions between contaminant particles and spray droplets. Preferably, hydraulic nozzles are used which emit a hollow cone spray. The spray droplets are preferably in the range of 40-200 microns mean mass diameter (MMD).

摘要： A two-fluid atomizing nozzle incorporating a novel nozzle cap is described. The nozzle cap comprises support spokes which couple a pintle to the outer frame of the nozzle cap for holding the pintle in position. The support spokes comprise dams which prevent liquid from flowing along the length of the support spokes to the outer frame of the nozzle cap. This improves atomization by causing any liquid which flows along the spokes to reenter the high disturbance region of the nozzle. Additionally, it reduces erosion of the support spokes, particularly near the end of the spokes adjacent to the outer frame of the nozzle cap. Moreover, it reduces erosion of the interior wall of the outer frame of the nozzle cap. In another embodiment the support spokes have a non-planar inlet surface to improve atomization and to reduce erosion of the support spokes and the interior wall of the outer frame.

摘要： An improved electrode assembly for a high-intensity ionizer array utilized as the first stage in a two-stage electrostatic precipitator. Each ionizer unit employs a pair of co-axial electrodes to create a high-intensity electric field across the path of a particulate-laden gas stream. As the gas passes through the field, it is intensely ionized and the particulate becomes highly charged. The ionizer anode comprises a venturi diffuser through which the gas stream flows immediately prior to entry into a precipitator stage which removes the charged particles. The ionizer cathode is a disk co-axially mounted within the venturi throat and having an arcuate periphery. A high voltage power supply connected between the anode and cathode establishes a high-intensity corona discharge in the annular region formed between the edge of the cathode disk and the surrounding cylindrical anode surface. Focusing electrodes at cathode potential are positioned on either side of the cathode disk and intensify the electric field along the anode wall at the fringes of the current flux band upstream and downstream from the corona discharge plane. This substantially reduces the width of the anode surface subjected to corona current and minimizes anode cleaning requirements by reducing the particle deposition area.

摘要： An electrostatic precipitator having an inner electrode extending along the axis of a tubular outer electrode. The inner electrode includes an elongated support electrode connected to a disc shaped discharge electrode having a transverse dimension larger than the transverse dimension of the support electrode. A high potential applied between the outer electrode and the support and discharge electrodes produces a relatively thin, radially and circumferentially uniform electrostatic field between the discharge electrode and the outer electrode, and a non-corona producing electric field between the support electrode and the outer electrode. A particle entrained gas is directed into the outer electrode at the discharge electrode end. The particles are charged by the thin, intense electrostatic field adjacent the discharge electrode, and are subsequently accelerated toward the outer electrode by the electric field extending between the support electrode and the outer electrode. The particles are then deposited on the walls of the outer electrode where they are removed by a film of liquid flowing along the inner surface of the outer electrode. In an alternate embodiment a plurality of discharge electrodes of either uniform or varying transverse dimensions are spaced apart along the support electrode to provide multiple charging and collection states through which the gas sequentially passes.

摘要： A venturi increases the velocity of contaminated gases and guides the gases past a high, extremely dense electrostatic field presented perpendicular to the gas flow and extending radially outward between a central, accurately sized disc electrode and the surface of the venturi throat. Downstream, charged particles are collected by a wet scrubbing process or electrostatic precipitator.
