摘要:
A system for treating radon in the air including at least two carbon electrodes. Each carbon electrode is formed from a mixture of activated carbon, gilsonite, and zeolite which is extruded into the shape of an elongated rod. Positively-charged radon ions in the air are attracted to the electrodes. There is also provided a method for removing radioactive radon isotopes from the air including the steps of: (1) providing at least two carbon electrodes formed from activated carbon, gilsonite, and zeolite; and (2) initiating a chemical reaction between the activated carbon and the radioactive radon isotopes to half-life the radon isotopes into non-radioactive isotopes.
摘要:
A hand dryer assembly including a blower assembly for generating a moving air stream. The moving air stream passes through an air channel to an air outlet where it exits the hand dryer assembly. An ionization assembly is disposed along the air channel and emits charged ions directly into the moving air stream, sanitizing the hands of the user, the moving air steam, and the ambient air that is entrained into the moving air stream.

A method and apparatus are provided for reducing quench water required by a wet electrostatic precipitator. The apparatus includes a wet electrostatic precipitator and an evaporator in flow communication with the wet electrostatic precipitator to evaporate at least one portion of bleed water discharged from the wet electrostatic precipitator into steam. The method includes directing at least one portion of bleed water discharged from the wet electrostatic precipitator to an evaporator and directing at least one portion of flue gas from a boiler to the evaporator. The energy of the at least one portion of flue gas is used to evaporate the at least one portion of the bleed water into steam. The steam is directed to the wet electrostatic precipitator. The at least one portion of flue gas is directed from the evaporator to the wet electrostatic precipitator.
摘要:
An apparatus and method remove particulate matter from a gas. The apparatus has an inlet for receiving a contaminated gas having particulate matter, and for inducing a swirl to the contaminated gas. A cyclonic separation stage including a first flow-path is provided for separating a portion of the particulate matter from the swirl-induced contaminated gas by centrifugal action, to produce a partially clean gas. An ionization stage including a second flow-path is provided for ionizing the particulate matter remaining in the partially clean gas by producing a corona discharge in the second flow-path. A particle collection stage including a third flow-path is provided for separating the ionized particulate matter from the gas using an electric field across the third flow-path, to produce a clean gas. The ionization stage and the particle collection stage are arranged such that the third flow-path has an increased cross-sectional area relative to the second flow-path.

Aggregation of particulate matter is facilitated. Provision is made for an electrode arranged in an exhaust passage of an internal combustion engine, a power supply connected to the electrode for applying a voltage thereto, an air fuel ratio detection device to detect or estimate an air fuel ratio of an exhaust gas which flows through the exhaust passage, and an electric power control device to make electric power supplied to the electrode from the power supply larger in cases where the air fuel ratio detected or estimated by the air fuel ratio detection device is a rich air fuel ratio than in cases where it is a stoichiometric air fuel ratio or a lean air fuel ratio.

A method and apparatus are provided for reducing waste effluent from a system including a boiler and a wet electrostatic precipitator, the waste effluent having blow down water discharged by the boiler during a blow down operation and bleed water discharged by the wet electrostatic precipitator. The method includes collecting the blow down water and providing it to the wet electrostatic precipitator as a makeup water supplement, evaporating a portion the bleed water and leaving residual bleed water, providing the evaporated bleed water to the wet electrostatic precipitator as a further makeup water supplement, and using the residual bleed water to quench ash produced by combustion of solid fuel by the boiler. The apparatus includes an evaporator that provides direct contact between hot boiler flue gas and the bleed water such that a portion of the flue gas is quenched before being provided to the wet electrostatic precipitator.

An electro-kinetic or electro-static apparatus for moving fluid includes an enlogated electrode energizable with respect to at least one other electrode to generate ions and thereby motivate fluid flow there between. A cleaning device is positioned to frictionally engage at least two opposing surfaces of the elongated electrode. The cleaning device is movable along a length of the elongated electrode to thereby remove detrimental material from the at least two opposing surfaces of the elongated electrode. The cleaning device can be substantially off-center relative to the elongated electrode to frictionally bind upon the elongated electrode during movement of the cleaning device.
摘要:
An emissions reduction stack comprises a conditioning section, collector section utilizing a Wet Electrostatic Precipitator (WESP), and output section. A chemically active aqueous stream is introduced into an incoming process stream in order to saturate the stream and produce a fog stream wherein water is condensed on the surface of particulates. The process of condensation increases the efficiency of the particulate filtration process conducted by the WESP.
