    摘要： Systems and methods related to the collection of a species from a gas stream are generally provided. The systems and methods described herein may allow for collection of a species such as a fluid (e.g., water) with a relatively high collection efficiency. Such systems and methods may be useful in various applications including, for example, fog collection. In some embodiments, the systems and methods enhance water collection from airborne fog to produce usable water. Advantageously, the methods described herein may, in some cases, incorporate ions into the gas stream such that the species present in the gas stream follows electric field lines and/or are attracted to a grounded (or charged) collector. Advantageously, the systems and methods described herein may suppress the adverse effects of natural conditions such as the velocity and direction of the wind.

    摘要： Fine particles of dust and other pollutants in gas streams are agglomerated to form larger particles which are more easily filtered in downstream processing. In one embodiment, particles in successive portions of the gas stream are charged with opposite polarity, and the gas stream is introduced into an Evasé portion (12) to slow it down. Particles of different sizes have differential deceleration and therefore mix generally in the direction of flow, leading to agglomeration of oppositely-charged particles. In another embodiment, a gas stream is divided into substreams in respective parallel passages, and the particles in adjacent passages are charged to opposite polarity. Deflectors at the downstream end of the passages cause substreams of particles of opposite polarity to mix, with resultant agglomeration of oppositely charged particles.

    摘要： A process for the in-situ transformation of chemical species present in the flue gas to form sulfur trioxide, wherein the fly-ash particles are conditioned by altering their surface electrical properties. More specifically, the subject invention is concerned with fly ash conditioning using plural lamps located at specific positions in a specific arrangements most advantageous to the chemical conversion that would take place. The novel invention conditions flue gas emissions by treating the flue gas with SO.sub.3, where the SO.sub.3 is generated in the flue gas by photocatalytic conversion of SO.sub.2 using selectively spaced and arranged ultra violet light emitting lamps and related automated components. A preferred embodiment of the invention describes the novel process with a large-scale flue gas emission plant having an electrostatic precipitator(ESP) and flue gas stack where a novel feedback control system operates the various UV lamps by measuring power output of the ESP and an opacity sensor for the plume being emitted from the stack.

    摘要： A method for reducing the sulfur content in combustion gases from burning coal includes the steps of applying opposite electrostic charges to fuel particles and to reaction particles, and mixing the oppositely charged particles prior to combustion to facilitate the formation of sulfur compounds from sulfur in the fuel upon combustion of the fuel, to thereby reduce the sulfur content in the combustion gases. The reaction particles are preferably a carbonate such as CaCO.sub.3 and MgCO.sub.3. The apparatus for implementing the method includes a first pneumatic line for conveying fuel particles, and a first electrostatic charging device for applying an electrostatic charge to the fuel particles conveyed in the line; and a second pneumatic line for conveying carbonate particles, and a second electrostatic charging device for applying an electrostatic charge to the carbonate particles conveyed in the line that is opposite in polarity to the charge applied to the fuel particles. The first pneumatic line and the second outlet line are electrically insulated from each other but outletting to a chamber in sufficiently close proximity to allow the fuel particles and carbonate particles to mix prior to combustion.

    摘要： A method for use in an electrostatic precipitator unit, of controlling, with a view to cleaning an incoming dust-laden gas, the supply of conditioning agent to the incoming contaminated gas upstream of the precipitator unit. The precipitator unit includes discharge electrodes and collecting electrodes, between which a varying high voltage is maintained by means of a pulsating direct current supplied thereto. The frequency, the pulse charge and/or pulse length of the pulsating direct current are so varied that a plurality of frequency-charge-length combinations are obtained. For each combination, a figure of merit is measured or calculated. The figures of merit are used for establishing an optimal combination. The supply of conditioning agent is adjusted in dependence upon the pulse frequency of the established optimal combination.
