An air purifying device has a housing, a blower assembly disposed within the housing for blowing air, an electrically-charged electrostatic plate, and a thermal layer for heating the air to a temperature of at least 75 degrees Celsius, and preferably at least 180 degrees Celsius. The electrostatic plate is connected to a high voltage power supply providing a voltage of at least 3 kilovolts and preferably at least 30 kilovolts. The blower assembly moves the air through the thermal layer at a volume of at least 0.25 cfm and preferably at a volume of less than 15 cfm.

An improved high-efficiency electrostatic air filter device implements a dust collection function and incorporates a material that captures and that is toxic to viruses/bacteria and causes viruses and bacteria to be rendered harmless by contact with this material. The device is composed of a charging section having a conductive antiviral media to charge any particles in the gas with a high electric voltage and a collecting section which contains or is composed of conductive material which has antiviral/antibacterial properties and a surface of opposite polarity or lower potential that will cause the aforementioned charged particles to adhere to the toxic material as the gas flows through or around the media. The collection section is formed with or coated by an inactivating material that inactivated pathogens when physically contacted.

There is provided a system and method for collecting water droplets from an airflow of a cooling tower (8) through condensation of water vapour using an electrostatic separator (20), wherein the electrostatic separator is a single unit electrostatic separator (20) or a multi-unit electrostatic separator. The method for water particles collection from the exhaust airflow of a cooling tower primarily comprises condensing water vapour into large water droplets. It is experimentally proved that electrostatic separation solves the problem of visible plume pollution, and blow down decreased since collected water flows back to the circulating water. Additionally, electrostatic separation results in small pressure drop of the cooling tower (8).

An electrostatic precipitator module and a desulfurization system are capable of easily discharging wash water from a wet electrostatic precipitator module. The electrostatic precipitator module includes an arrangement of discharge electrodes and collecting electrodes alternately disposed and spaced apart from each other, the discharge electrodes configured to be charged to a predetermined voltage for generating a corona discharge between the discharge electrodes and the collecting electrodes; and tie rods for fixing the discharge electrodes and the collecting electrodes. Each collecting electrode has a lower edge inclined downward with respect to the ground. The lower edge of each collecting electrode includes separate lower edge portions respectively inclined downward from opposite side ends of the collecting electrode and a lowermost point at which wash water is concentrated and discharged to a discharge guide installed directly under the lowermost points. The discharge guide has a width substantially smaller than the collecting electrode.

The present invention is a directed to an integrated ionic air mover that provides air flow rates through an opening within the a printed circuit board (PCB), or other similar insulating surface, to create the structure of the air mover, so that high heat generating components mounted on the PCB can be cooled. The ionic air mover has sharp and blunt electrodes with a corona discharge taking place in the air gap in between the electrodes. A directional emission of the ions creates an ionic wind the moves air through the PCB. The invention provides a low-cost structure, while achieving high electro-air flow power conversion efficiency and air-flow performance integrated into the PCB that the heat generating components are mounted on. The ionic air mover may also be surface mounted to a PCB and include a transmittal coil for wireless charging.
