Abstract: An electrostatic air precipitator electrode system where the particle collecting electrode or the particle collecting electrode and the repelling electrode are made of a unitary conductive polymer material, preferably a conductive synthetic polymer material. Parts of the conductive synthetic polymer collecting electrode are treated to enhance the surface area. The treatment may be mechanical, chemical, or otherwise applied to enhance the surface area of the electrode. The repelling electrodes may also be made of a conductive polymer material, preferably a conductive synthetic polymer material. The advantage of having a unitary collecting electrode and a unitary repelling electrode both made of the same or similar material is that they may be recycled as a unit under recycling protocols requiring unitary materials and may be rigid enough to reduce the spacing that would have been required with foam based electrodes.

Abstract: An electrostatic precipitator particle collection unit with a particle collecting electrode and a repelling electrode fabricated with static dissipative materials. The static dissipative material may be a polymer, may be a synthetic polymer, and may be a moldable polymer. The electrode plates may be formed from thermoplastic or thermoset polymer.

Abstract: An electrostatic air precipitator electrode system having collecting electrodes made of a conductive polymer material, preferably a conductive synthetic polymer material. The repelling electrode may be integrated with ion-emitting sites to avoid the necessity of a separate corona electrode in an electrostatic precipitator. Ion emitting structures are portions of the electrode that have very small diameters. Molded ion emitting sites may be in the form of pointed cones or knife-like ridges. Features of reduced diameter to be ion emitting sites may be formed in metallic repelling electrode by mechanical disruption such as punching, cutting, or sawing the repelling electrode at or near the end of the electrode near the inlet end of the particle collecting structure. The repelling electrodes may also be made of a conductive polymer material, preferably a conductive synthetic polymer material.

Abstract: An electronic air filter containing a tubular collecting electrode and an ion emitting electrode located concentrically inside of the tube-like collecting electrode, the collecting electrode consists of outer electrically conductive shell and inner layer made of open cell porous material.

Abstract: An electronic air filter containing two separate parts: an inlet part and an outlet part; an ionizer located in the inlet part; a collector located in the outlet part; the inlet part is detachable from the outlet part. The inlet part is a door. The outlet part contains detachable set of collecting electrodes.
