The invention relates to a gas flow cleaning device (100) comprising a corona electrode (102) provided with corona tips (102A), and a non-corona electrode (104). A gas flow generator (106) generates a flow along the corona electrode and non-corona electrode. The corona electrode (102) comprises at least one disclike member (102B). The disclike member (102B) comprises a disclike support part (202) and a number of conductive bendable wires (204) attached to the disclike support part (202). A corona tip (102A) is a free end (204A) of a conductive bendable wire (204). A part (204B) of the conductive bendable wire (204) is wound around a protrusion (202A) of the disclike support part (202).

A pollution management system comprises an array of one or more polluted air inlets such as suction heads or vents 220, arranged to collect polluted air and supply the polluted air to a polluted air treatment element 210. Polluted air may be transported by fans 230 and/or other convection devices via suitable ducts and/or pipes 240 to the treatment element such as a gaseous or particulate matter treatment element. Sensors 270 may be provided along the ducts to sense contaminants such as particulate matter or NOx and SOx and are arranged to provide feedback to the polluted air treatment element where particulate and gaseous pollutants are removed either in stages or simultaneously. Advantageously the system can be used to reduce the atmospheric pollution in urbanized and/or industrialized areas.

The invention relates to a fluid displacement device (2) configured for generating a flow within a fluid. The fluid displacement device comprises an airflow duct (4) with an inner surface (4C) configured to accommodate a flow of fluid. A number of corona electrodes (6A) is disposed in the airflow duct wherein each of the corona electrodes comprises an elongated body (6A2) with a distal end (61) and a proximal end (62). The distal end is provided with a tip structure (6A1) configured to generate a corona discharge. A non-corona electrode (6B) is disposed downstream the corona electrodes, the tips (6A1) of the corona electrodes (6A) are positioned at a predefined distance (d) from the non-corona electrode (6B), and the proximal end joins the inner surface of the airflow duct (4) at a distance from the non-corona electrode which is longer than the predefined distance d.
摘要:
The invention relates to tube-like element (100) for use in a duct system as filter holder. The tube-like element comprises a cylindrical wall component (102) which forms a duct (103). The cylindrical wall component comprises at least one oblong opening (104) configured to position a removable disc-shaped element (402) in the duct. Circular beads (106) in the cylindrical wall component form opposite longest edges (107) of the opening. The circular beads are configured to restrict movement of a removable disc-shaped element (402) that is positioned in the duct. The movement is restricted in axial direction of the duct.
