An easy-to-clean separable purification core for an air purifier includes an inner cavity lining body, a collector module and a repeller module that are detachably inserted one in the other. The collector module includes a first collector cell and a second collector cell that are nested from top to bottom and are detachable with respect to each other, the two collector cells match each other in shape and dimension size and are respectively provided with collector pieces parallel to each other, and the spacing between two adjacent collector pieces in each collector cell is four times of an original spacing. In an assembly state of the purification core, the collector module, the repeller module, and the inner cavity lining body are nested one in another to form an integral component.

An electrostatic binning precipitator separates solid particles from gases and vapors and sort the solid particles based upon size, density, or morphology. The electrostatic binning precipitator includes a precharger, electrostatic cells, and optionally a heat exchanger. The precharger applies a negative charge to the solid particles that are then collected in one of the electrostatic cells. Each of the electrostatic cells has an independent power supply that applies a voltage to center negative electrodes that are partially surrounded by grounded concave shells. Lower voltage electrostatic cells collect smaller solid particles and higher voltage electrostatic cells collect larger solid particles. The solid particles are moved from the shells into collection hoppers. Gases and vapors can optionally flow into a heat exchanger that can condense these particles into liquids that are collected in reservoirs. The collected solid particles and liquids can be used for industrial applications or safely disposed.

Methods and apparatus for cleaning contaminant byproducts off of ionizing wire electrodes in ionizing blowers are disclosed. Disclosed apparatus include a housing with a gas-flow channel, an stationary ionizing wire, and a rotatable frame with supports for resiliently supporting the stationary ionizing wire within the channel. The ionizing wire produces charge carriers and has a surface that develops a layer of contaminant byproducts when an ionizing signal is applied thereto. The frame is rotatably mounted such that the supports clean the layer of contaminant byproducts off of the surface of the ionizing wire when the frame is rotated. Disclosed methods include providing an ionizing signal to the ionizing wire to thereby produce charge carriers and rotating the frame relative to the housing to thereby clean contaminant byproducts off of the ionizing wire.
