Filed:

Sep 26, 2001

Appl. No.:

09/964055

Inventors:

Dean B. Pruette - Sanford NC
Charles A. Rector - Chapel Hill NC
David R. Phelps - Greensboro NC

Assignee:

Fedders Corporation - Liberty Corner NY

International Classification:

B03C 372

US Classification:

96 26, 96 60, 96 73, 96 86, 96 87, 96100

Abstract:

A modular two-stage electrostatic precipitator for extracting airborne particles includes individual ionizer/collector cell modules having integrated power supplies and diagnostic systems. The cell modules are adapted to be joined blindly to one another in end-to-end nested relation through nestable end plates and in a series circuit utilizing floating electrical connectors. The module end plates provide self-correction in misalignment during a blind connection and provide sealed end plate cavities for the power supply and electrical connections. The diagnostic system provides detection for any open system circuit and/or short circuit condition and allows for trouble shooting on an individual cell module basis.

Appl. No.:

7/943543

Inventors:

Charles A. Rector - Chapel Hill NC
J. Clayton Rosser - Broadway NC

Assignee:

Trion, Inc. - Sanford NC

International Classification:

B03C 340

US Classification:

96 60

Abstract:

A device for use in an electrostatic precipitator including an electrically insulating disk having a hole, which may be a venturi-shaped passage, for receiving a tie rod and an arrangement for supporting the tie rod in the hole so as to allow a fluid to flow through the hole between an inside surface of the hole and the tie rod. An air stream deflector may be mounted on the tie rod to provide further protection and help direct air flow. A recirculating flow system may also be provided to direct clean air through the venturi-shaped passage.
