A base body of a dust collector includes a pedestal, and partition plates arranged on the pedestal. The partition plates are made of insulating materials. A plurality of baffle partition plates are arranged in a length direction of the pedestal at intervals. A slot for inserting electrode sheets is formed between the adjacent partition plates. The dust collector includes the base, and further includes a collector electrode sheet and a discharging electrode sheet.

A panel for accumulation of aerosol particles in an indoor environment includes a surface plate and an electrostatic collector plate coupled to the surface plate and configured to hold an electrical charge to attract and accumulate aerosol particles. The panel may include or otherwise be coupled with an activation device.

An electrostatic precipitating apparatus for an air conditioning system is disclosed. The precipitating apparatus includes an electrostatic precipitator including a plurality of discharge electrodes to which a voltage is applied and a plurality of electrostatic precipitating electrodes each disposed between the discharge electrodes and grounded, a washing water supply spraying the washing water to the electrostatic precipitator, and a frame assembly fixed to the duct to support the electrostatic precipitator. The frame assembly is fixed to the duct to support the electrostatic precipitator, and includes a prestressing locking member fixed to inside of the duct in a state in which a pressing force is applied to the electrostatic precipitator.

An electrostatic dust collection apparatus and an air purifier including such the electrostatic dust collection apparatus are provided. The electrostatic dust collection apparatus of the invention includes a sheet collection electrode, an insulative bearing member and a plurality of discharge electrodes. A first surface of the sheet collection electrode faces and is parallel to a second surface of the insulative bearing member. A plurality of grooves are formed on and across the second surface of the insulative bearing member, and are parallel to one another. Each discharge electrode corresponds to one of the grooves, and is disposed in the corresponding groove. An air passage is defined between the sheet collection electrode and the insulative bearing member, and allows an air to be treated to pass through. The discharge electrodes charge a plurality of floating particles in the air to be treated. The sheet collection electrode collects the charged particles.

An electronic air filter having a plurality of electrodes supported by rigid fixtures that are attached to a common case. The rigid fixtures that support the electrodes with different electrical potentials are attached to each other or to a common body in a way that increases or maximizes the creeping discharge path along the surface. Even conductive contaminants do not, therefore, provide an electrical shortage between the electrodes.

Method and apparatus for cleaning pollution control equipment, such as particulate removal devices, including wet electrostatic precipitators (WESP). The WESP may include a housing, at least one gas inlet in fluid communication with the housing, a gas outlet spaced from the at least one gas inlet and in fluid communication with the housing, one or more ionizing electrodes in the housing adapted to be connected to a high voltage source, and one or more collection electrodes in the housing. The housing may be in fluid communication with a flushing fluid source, such as a water source. The effective length of the collection electrodes is increased with extensions which add significant surface area to the collection electrodes while minimizing the corresponding height increase.
