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. |
