Title:
ARRAYED ELECTRICALLY CHARGED SPRAY AXIAL FLOW CYCLONE FILTER TUBES
Document Type and Number:
WIPO Patent Application WO/2021/047203
Kind Code:
A1
Abstract:
Arrayed electrically charged spray axial flow cyclone filter tubes, comprising: axial flow cyclone filter tubes (10), a liquid-providing spray pipe (11), electrostatic atomization nozzles (12), the electrostatic atomization nozzles being in communication with the liquid-providing spray pipe, and a high voltage power supply (13), a high voltage power supplying end of the high voltage power supply being connected on electrostatic induction rings (122) of the electrostatic atomization nozzles. When a conductive liquid solution sprays out of the electrostatic atomization nozzles, induced electrical charge is produced under the action of a high voltage electric field, and the surface tension of the electrically charged liquid droplets decreases, which allows the particle size thereof to further decrease; when driven by external air, the sprayed electrically charged liquid droplets rapidly enter into the axial flow cyclone filter tubes together with dust-containing air flows, and at the inner walls of the axial flow cyclone filter tubes the electrically charged liquid droplets and the dust-containing air flows form forward-spiraling gas/liquid/solid multiphase mixed air flows. Under the cumulative action of electrostatic adsorption, collision, and diffusion, high mass particles are formed, which strengthens the centrifugal force and inertial force of the particles during movement, improving the dust-removal effect.
