A braking system for safely collecting brake dust produced by operation of a braking mechanism. The braking system comprises a collector apparatus coupled with a braking mechanism. The collector apparatus is able to include a shroud that surrounds the braking mechanism and a catch element coupled with the shroud for collecting brake dust exiting the shroud. As a result, when coupled with the braking mechanism, the collector apparatus is able to ensure that most or all brake dust, such as copper or other particles from the braking mechanism that break off from the breaking mechanism during operation of the braking mechanism, are removed from the braking mechanism and collected by the filter/catch of the collector mechanism.

The core component of the device is a purification system; the purification system comprises a headstock, a container and a purification system which are connected with the back of the headstock, and the purification system is arranged in the container, and comprises a purification tower I and a purification tower II, wherein the purification tower I comprises a tower body I, corona electrodes I and conductive filters; the purification tower II comprises a tower body II, corona electrodes II, a sprinkler system and electrofiltration coupling units.

An electrostatic charging air cleaning device having first and second pre-chargers. The first pre-charger is configured to generate a first corona discharge to electrostatically charge PM in the incoming air stream with a first charge to form a first exiting air stream exiting the first pre-charger. The second pre-charger is configured to generate a second corona discharge to electrostatically charge PM in the incoming air stream with a second charge to form a second exiting air stream exiting the second pre-charger. The device also includes a separator having apertures such that PM in the second exiting air stream passes through the separator to agglomerate with PM in the first exiting air stream to form agglomerated particles. The apertures are sized such that the agglomerated particles are larger than the apertures to preclude the agglomerated particles from reentering the second exiting air stream.

Disclosed is an apparatus for enhancing filtration. Enhanced filtration is promoted via the eccentric movement of charged particles within a defined space. This eccentric movement causes the charged particles to collide and conglomerate. The conglomeration, in turn, improves the efficiency of downstream filer media.
