  • Patent number: 10926272
    Abstract: An electrostatic precipitator (1) to precipitate one or more materials (9) out of an exhaust gas flow (5) has a spray electrode (2) having an active part (14) for generating a corona discharge (6) and a flushing liquid supply (21), by means of which flushing liquid (10) is supplied into the precipitator (1) for removing deposits (11), made of the material(s) (9) to be separated, that settle on the spray electrode (2). The precipitator (1) uses less cleaning liquid and the cleaning is carried out more reliably. For this purpose, a flushing device (8) directs the flushing liquid (10) across a head region (12) of the spray electrode (2) onto the active part (14) of the spray electrode (2) as a flushing stream (22).

  • Patent number: 10864526
    Abstract: An improved electrode for use in an electrostatic precipitator is disclosed. The electrode comprises a generally rod-shaped conductive central portion, to which are attached a plurality of conductive disc-shaped elements. Each disc-shaped element has a number of sharp points spaced around its circumference and a plurality of openings near its center. The central portion of the central portion passes through the centers of each of the plurality of disc-shaped elements such that the disc-shaped elements are located parallel to one another along the central portion, and may be equally spaced along the central portion. The disc-shaped elements are conical or convex in shape, and oriented with their rims raised above their centers so that any water that collects on them runs out through the openings and down the central portion of the electrode. This greatly reduces or eliminates arcing between the electrode and a collector in the electrostatic precipitator.

  • Patent number: 10857547
    Abstract: A device and method is provided for separating associated ions within a gaseous fluid stream into a first population of positively-charged hydrated hydrogen ions and a second population of gaseous hydrated anions. The device employs a housing and spinning wheel within a vacuum chamber to expose a flow of associated ions to a combination of microwaves and magnetic energy within the vacuum to cause bifurcation of the associated ions into a first population of positively-charged hydrated hydrogen ions and a second population of gaseous hydrated anions which may be collected in reservoirs. The collected two populations can be further channeled through a transformer to electrically induce a force for locomotion or communication.

  • Patent number: 10814261
    Abstract: Filter media, such as electret-containing filtration media for filtering gas streams (e.g., air), are described herein. In some embodiments, the filter media may be designed to have desirable properties such as stable filtration efficiency over the lifetime of the filter media, increased normalized gamma, relatively low pressure drop (i.e. resistance), and/or relatively low basis weight. In certain embodiments, the filter media may be a composite of two or more types of fiber layers where each layer may be designed to enhance its function without substantially negatively impacting the performance of another layer of the media. For example, one layer of the media may be designed to have a relatively low basis weight and/or a relatively high air permeability, and another layer of the media may be designed to have stable filtration efficiency and/or a relatively high efficiency throughout the filter media's lifetime.

  • Patent number: 10814336
    Abstract: Known wet electrostatic precipitators are large and inefficient. The present invention enables the production of smaller, more efficient and long lasting wet electrostatic precipitators by the addition of a central bore in the inner electrode through which a first purge flow is passed and directed into the precipitator chamber, perpendicular to the direction of flow of the gas to be treated through the chamber to urge the particulate into the water curtain. A second, larger, cleaning purge flow is also provided to disturb the water curtain such that it cleans the inner electrode of any deposited particulate.
