摘要： An electrostatic gun for electrostatically charging and injecting sorbent particles into a flue gas stream to contact, and electrostatically charge, pollution particles in that flue gas stream. The electrostatic gun is for inclusion as a component of an apparatus for the remediation of pollution particles from a flue gas stream whereafter the clean gas flow is vented to atmosphere. The electrostatic gun receives laminar flow of a selected sorbent material and charges, either positively or negatively, the surface of each sorbent particle in that flow. To provide electrostatic charging to the individual particles, the flow is directed through a straight barrel of a housing of the electrostatic gun to pass alongside a charging wand that is centered axially in the straight barrel. The charging wand is connected to receive a voltage from a high voltage power supply to produce a corona discharge wherethrough the sorbent materials pass to electrostatically charge each sorbent particle. The invention includes a corona enhancement arrangement in the form of a grounding ring or opposing grounding plates arranged in the barrel and spaced apart from the charging wand, that carry a charge that is opposite to the charge on the charging wand enhance the generation of the corona discharge around the charging wand, greatly increasing the sorbent particle charging efficiency to where essentially all the sorbent particles that pass through the gun will receive a surface charge.

摘要： A hopper system and electrostatic gun for injecting electrostatically charged sorbent particles into a polluted gas stream for inclusion in an apparatus that utilizes electrostatically charged sorbent particles for removing particulate matter and gases from a polluted gas stream. The invention includes a hopper system with a bin that is selected to hold a required volume of dry sorbent material and is arranged to feed a metered quantity of sorbent materials, preferably by a screw feed, to receive an air flow from a regenerative blower the air flow mixes with sorbent materials in a throat of a venturi line and transports that flow into a barrel an electrostatic gun. The air entrained sorbent materials travel around and along a charging wand that is centered longitudinally in the barrel bore, and is electrically connected to received a controlled voltage from a high voltage power supply. The charging wand provides an electrostatic charge to all the sorbent particles passing thereby that are then passed into and are rapidly dispersed in the polluted gas stream so as to provide a large charged area in the flow for electrostatically charging, by charged sorbent particle contact, the pollution particles and attracting submicron size of pollution particles. Agglomerized sorbent and pollution particles are thereby formed that are then removed, by passage through a series of filter beds of media materials that as selected for the particular agglomerized pollution and sorbent particles, cleaning the gas stream that is then vented to atmosphere.
