An electric dust collecting filter includes a plurality of film electrodes that are arranged apart from each other at regular intervals and form an electric field to collect foreign matter in the air. The film electrode includes an insulating part that defines one surface and the other surface of the film electrode, a first electrode part disposed on one side inside the insulating part and having a plurality of first wire electrodes spaced apart from each other, and a second electrode part disposed on the other side inside the insulating part and having a plurality of second wire electrodes that are disposed between the plurality of first wire electrodes spaced apart from each other and provided alternately with the plurality of first wire electrodes.

An example of a species collection system includes a plurality of spaced-apart electrically conductive collectors and a plurality of emitter electrodes. In some embodiments, at least one emitter electrode is disposed between adjacent ones of the collectors. In some embodiments, the at least one emitter electrode extends beyond the collectors (e.g., in at least one dimension). Collectors may be aligned to a direction of gas flow from an outlet (e.g., of a cooling tower) to facilitate collection while minimizing interference with the gas flow. Different emitter electrodes may be maintained at different voltages. In some embodiments, collectors are attached to a collector frame and emitter electrodes are attached to emitter frame(s) that are electrically insulated from the collector frame. Collectors may span a gas outlet (e.g., of a cooling tower) and emitter frame(s) may be positioned outside of the collectors (e.g., and outside of a periphery of the gas outlet).

An air vent system includes a conduit for airflow. A stream of air is moved through the conduit.

An electrostatic air cleaner may include a corona charging stage, a precipitation stage, and an air mover (fan). The corona charging stage may include a first and second array placed under electrical potential difference capable of generating a corona discharge. The first array may be substantially parallel corona wires and may be located downstream of an air penetrable second array. The precipitation stage may be downstream from the corona charging stage. The spacing between the first array and the second array may be less than the distance of the precipitation stage to the second array. The air mover may be upstream of the corona charging stage or downstream of the precipitation stage or between these stages. The arrangement allows for higher ion output downstream of the first array with the same voltage and power consumption resulting in greater particle charging and better air cleaning efficiency.

An example of a panel for use in collecting fluid in a gas stream includes a fluid collection member comprising one or more collection electrodes. The panel may include an emitter electrode assembly member comprising an emitter electrode frame and one or more emitter electrodes attached to the emitter electrode frame (e.g., disposed in a one- or two-dimensional array). The one or more emitter electrodes may be physically separated from the one or more collection electrodes. The fluid collection member may be physically connected to the emitter electrode assembly member. The one or more collection electrodes may be electrically insulated from the one or more emitter electrodes.

A helmet includes a helmet body and a gas detection and purification device. The gas detection and purification device in includes a body, a purification module, a gas-guiding unit, a gas detection module, and a power module. The gas detection module calculates the gas detection data obtained by the gas detection module so as to control the gas-guiding unit to start or stop operation based on the gas detection data. When the gas-guiding unit is in operation, the gas-guiding unit guides the gas into the body and to pass through the purification module for being filtered and purified to become a purified gas, and the gas-guiding unit discharges the purified gas out of the body to the nose portion, or the mouth portion, or both the nose portion and the mouth portion of the wearer for providing the wearer with the purified gas to breath.
