Component parts of the equipment of electrostatic precipitator:
Gas-distribution plane lattices
Perforated flitch plates, aggregated into one continuous flat baffle with effective cross-section - 0.45 - 0.50, which form tandem of gas-distributor in rows, one after the other.
On customer's agreement some part of the lattices could be replaced with concentrate of major particles, which is installed on inlet and outlet of the chamber of electrostatic precipitator's body.
Corona-forming electrode:
Framed tubular structure of the flat form with the corona-forming electrodes, stringently fixed in the plain of the frame. As the corona-forming elements, the longitudinal drawn or rolled profiles of smooth or acicular form (both singl and decomposed) are used.
System of corona-forming electrodes rack and regeneration:
Electrically insulated, gathered into a single unit, system of mechanical elements with a support on body by means of insulators; includes immovable supports and moving elements for shock-and-hammer regeneration of corona-forming elements from the layer of electrodepositioned solid disperse phase (dust).
Body:
It is à hermetic steel compartment of rectangular form (welded construction), composed of sections as to number of electric fields. Walls of the compartment is made from modules of finned sheet steel, are heat insulated and covered with decorative panels of encasements.
Bunkers, diffuser, convergent tube:
These are hermetic steel compartments of pyramidal type, welded construction. Walls are made from modules of a finned sheet steel, are heat insulated and equipped with built-in heaters; they are equipped with inspection doors and impenetrable scuttles.
Collecting electrode:
Profile metal plates, which are gathered into the system of a plate electrode by means of beams.
Principles of operation of the electrostatic precipitator:
Particles of dust, existing in gas, are charged in a field of corona discharge, and under the influence of its forces they are drifting towards collecting electrodes. When reaching collecting electrodes the particles touch with their surface, discharge and by means of strength of adhesion and autohesia they form electrosdeposited layer. Under a scock-and-hammer influence on electrodes, the electrodeposited layer of dust has been regenerated and by means of conglomerates and under indluence of gravity forces, transported into bunker-accumulator of dust for the subsequent outlet from the device.
