Abstract:
The present invention provides methods and systems for a bipolar ionization device that includes an electrically insulated base, a power input terminal, an anode engaged to the base and the power input terminal, a cathode that partially circumscribes the anode, and plurality of tines extending perpendicularly from the anode having a lower portion and a top portion, wherein the lower portion is engaged to the anode and is wider than the top portion.
Abstract:
An emissions reduction stack comprises a conditioning section, collector section utilizing a wet electrostatic precipitator (WESP), and an 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.
Abstract:
Apparatus and methods for collection and removal of particulate matter, including fine particulate matter, from a gas stream, comprising a unique combination of high collection efficiency and ultralow pressure drop across the filter. The apparatus and method utilize simultaneous electrostatic precipitation and membrane filtration of a particular pore size, wherein electrostatic collection and filtration occur on the same surface.
Abstract:
The invention relates to a plant (100) for the gasification of biomass. It comprises a gasifier (10) and an apparatus (23) for the filtration of the gas. The apparatus comprises a scrubber (31), a tank (41), and a wet electrostatic precipitator (51). The scrubber is in fluid communication with the gasifier and with the tank, and is adapted for the injection of a washing liquid in the gas flow. The tank comprises a bottom area adapted for collecting the liquid and a top area adapted for holding the gas, separated by gravity. The wet electrostatic precipitator is in fluid communication with the top area of the tank, so as to receiving only the gas. The invention further relates to a gasifier comprising a gasification reactor (12), a grate (125) for the support of the biomass in the reactor (12) and a plug (126) for closing the middle part of the grate. The plug is vertically movable so as to close and/or open the middle part of the grate.
Abstract:
A bipolar ionization tube includes a cylindrical glass tube having an open end and closed end. A cathode is positioned within and is circumscribed by an interior surface wall of the glass tube. An anode circumscribes an exterior surface of the glass tube, where the anode is adapted for electrical connectivity with a first conducting terminal of a power supply. An electrically insulated end cap has a groove for receiving the open end of the glass tube, and the end cap is secured to the glass tube with at least one sealant. An elongated conducting terminal having a first portion extends through the end cap and is adapted for electrical connectivity with a second conducting terminal of the power supply. A second portion of the conducting terminal extends into the glass tube and is configured for electrical connectivity with the cathode.

Abstract:
The present invention is related to electro-kinetic air conditioner systems having at least one emitter electrode and at least one collector electrode. The emitter electrode can have a plurality of pins axially arranged about a center axis and can include a cleaning mechanism which removes debris and particulates from the pins when the emitter electrode and/or cleaning mechanism is moved. Preferably, a driver electrode is located within the interior of the collector electrode. A high voltage source provides a voltage potential to at least one of the emitter electrode and the collector electrode to thereby provide a potential difference therebetween.
Abstract:
An ionizing particulate scrubber is provided for the removal of particulate from a gaseous exhaust stream, said scrubber comprising two sections: a charging section and a collection section. The charging or ionizing section comprises one or more cylindrical tubular ground chambers each with a rigid threaded rod electrode extending through the center thereof. A transformer/rectifier (T/R) is provided to supply high voltage DC power to the electrode such that the cylindrical tubular ground chambers act as the ground to enable a corona to form on the threaded rod electrode. As the gas stream passes through the current flowing from the electrode to the cylindrical tubular ground chambers walls, the particulate contained within the stream is electrostatically charged. The collection system comprises either a fixed or fluid bed packed section which is constantly irrigated from above. Ground rods in the packing and liquid sump allow the entire section to act as a grounded collector for the charged particulate. The gas stream and charged particulate are immediately sent from the charge section to the collection section of the system, and clean gas is then passed through an entrainment separator section to remove liquid droplets.
