ELECTROSTATIC PRECIPITATOR AND AIR SUPPLY TERMINAL Russian patent published in 2000 - IPC

FIELD: air purification. SUBSTANCE: invention refers to electrostatic precipitator for separation of particles that includes unit to charge particles mounted across inlet of flow, at least one wire of corona discharge to charge particles and unit of particle collector mounted downstream from it. Unit of particle collector has two groups of laminated elements installed in parallel and in direction of flow through precipitator at specified distances one from another. First group of elements is connected to frame and second group of elements is insulated from precipitator and first group of elements. Laminated elements are produced from one or more non-hygroscopic polymer materials with specific resistance that lies preferably in range from 1 x 10² Ohm cm to 1 x 10⁸ Ohm cm or more preferably in range from 1 x 10³ Ohm cm to 1 x 10⁷ Ohm cm and more exactly in range from 1 x 10³ Ohm cm to 1 x 10⁴ Ohm cm. Invention is also related to air supply terminal which includes precipitator combined with heating compartment. EFFECT: precipitator is simple in design and economical in manufacture, it ensures high efficiency of purification. 10 cl, 9 dwg
