An electrostatic precipitator with circulating dust collection plates is provided, in which, in a housing for electrostatic dust collection that includes an inlet and an outlet formed therein, the dust collection plates are configured so as to be immersed in cleaning water while circulating in response to driving of a circulation drive motor, so that it is possible to automatically clean the dust collection plates without stopping the operation of the electrostatic precipitator, simplify a configuration for cleaning the dust collection plates, save cleaning water for cleaning the dust collection plates, reduce manufacturing costs, and facilitate follow-up management.

The present invention relates to an electrostatic precipitator (ESP) system (1) for removal of particles from a flue gas flowing in a flow passage (4) being delimited by a primary collection in the form of a collection plate (5). The system comprises a discharge electrode (11) arranged in the flow passage and connected to a high voltage generator (12) providing for an electric field around the discharge electrode. The system further has a secondary collection electrode in the form of a grid (101) arranged within the collection plate and made of an electrically conductive material. The presence of such a grid improves the efficiency of the precipitator. In some embodiments, the ESP system comprises an actuator (112) for moving the grid upwards and letting it drop onto an internal bottom structure (109). The movement between the collection plate and the grid as well as the impact force imparted to the dropping grid both result in a removal of collected particles.

A system for controlling an electrostatic precipitator includes a computer control system with a computer and a controller in operative communication with an electrostatic precipitator. The computer control system is operative to control performance of the electrostatic precipitator by controlling one or more of: a) a power supply that controls voltage between an electrically grounded vertical plate and a metallic wire electrode in the electrostatic precipitator; b) a first feeder valve and a second feeder valve in a hopper; and c) a power supply to an electrical coil in operative communication with a rapper.

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.

A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator includes an array of vertical wet cords stretched within a duct. The cords are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves. A plurality of these sieves are arranged to define a plurality of gaps, through which the exhaust flows. The sieves and thus the cords are space so that a vortex from a first cord affects an adjacent cord and subsequently cord. The particles are then absorbed in liquid, which can be passed through a heat exchanger filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.
