Method and apparatus for particle agglomeration

Fine particles of dust and other pollutants in gas streams are agglomerated to form larger particles which are more easily filtered in downstream processing. In one embodiment, particles in successive portions of the gas stream are charged with opposite polarity, and the gas stream is introduced into an Evasé portion (12) to slow it down. Particles of different sizes have differential deceleration and therefore mix generally in the direction of flow, leading to agglomeration of oppositely-charged particles. In another embodiment, a gas stream is divided into substreams in respective parallel passages, and the particles in adjacent passages are charged to opposite polarity. Deflectors at the downstream end of the passages cause substreams of particles of opposite polarity to mix, with resultant agglomeration of oppositely charged particles.

Air cleaner and its ionizing unit

When an ionization section is taken out of a main body housing of a conventional air cleaner in order to wash the ionization section, an ionization line may be cut by being accidentally touched. In order to avoid this problem, a pre-filter (7) is mounted on a front surface of an ionization and dust collection unit (6) so as to be detachable. The pre-filter (7) is slidably guided by guide furrings (23) in a sub-frame (12), and is mounted on a front surface of the sub-frame (12). When the pre-filter (7) is mounted, ionization lines (15) are not exposed, so that the pre-filter (7) protects the ionization lines (15). When the ionization and dust collection unit (6) is detached from the main body housing, therefore, there is no problem that the ionization lines (15) might be cut by being accidentally touched with worker's hands, for example.

Devices for removing particles from a gas comprising an electrostatic precipitator

Air or gas cleaners enhance the uniformity of the current density between an emitter and one or more receptor electrodes by positioning one or more insulators or effective resistors between the emitter and the receptor electrode. Insulators and / or effective resistors are used to shield select portions, e.g. the edges of plate-type receptor electrodes, from ionization current flowing between an emitter and unshielded portions. This allows more compact structures without ionization current concentrations at the shielded regions, and results in lower ozone generation for a given particle collection efficiency.
