Abstract
Official abstract text for this publication.
The present disclosure relates to an electric dust collector for generating an electric field by a high voltage electrode formed of a polymer. An electric dust collector according to the present disclosure includes a high voltage electrode to which a high voltage is applied, composed of a thermoplastic polymer and an inherently dissipative polymer, and a ground electrode to be grounded to generate the electric field with the high voltage electrode.
First claim
Opening claim text (preview).
What is claimed is: 1. A dust collector to collect charged particles, comprising: a first electrode to which a voltage is applied, the first electrode being formed of a semiconductive polymer that includes a thermoplastic polymer and an inherently dissipative polymer; and a second electrode that is grounded and generates an electric field with the first electrode to collect the charged particle, wherein the thermoplastic polymer includes acrylonitrile butadiene styrene (ABS), wherein the inherently dissipative polymer includes polyamide 6 (PA6), wherein the first electrode contains 10 wt % to 20 wt % of PA6 as the inherently dissipative polymer, and wherein a surface resistivity of the first electrode is in a range of 10 10 Ω/sq to 10 11 Ω/sq. 2. The dust collector according to claim 1 , further comprising: a terminal formed of a metal material and electrically connected to an external power source, the terminal applying the voltage to the first electrode. 3. The dust collector according to claim 1 , wherein the first electrode includes: a plurality of high voltage plates disposed in parallel of each other, and a high voltage rib which connects the plurality of high voltage plates. 4. The dust collector according to claim 3 , wherein the second electrode includes: a plurality of ground plates disposed in parallel of each other and the plurality of high voltage plates, and a ground rib which connects the plurality of ground plates. 5. An electric dust collector comprising: an electrifier that charges a suspended particle, a dust collector that generates an electric field to collect the charged particle, and a case accommodating the electrifier and the dust collector, wherein the dust collector includes: a first electrode to which a voltage is applied, the first electrode being formed of a semiconductive polymer that includes a thermoplastic polymer and an inherently dissipative polymer; and a second electrode that is grounded and generates the electric field with the first electrode to collect the charged particles, wherein the thermoplastic polymer includes acrylonitrile butadiene styrene (ABS), wherein the inherently dissipative polymer includes polyamide 6 (PA6), wherein the first electrode contains 10 wt % to 20 wt % of PA6 as the inherently dissipative polymer, and wherein a surface resistivity of the first electrode is in a range of 10 10 Ω/sq to 10 11 Ω/sq. 6. The electric dust collector according to claim 5 , further comprising: a terminal formed of a metal material and electrically connected to an external power source, the terminal applying the voltage to the first electrode. 7. The electric dust collector according to claim 5 , wherein the first electrode includes: a plurality of high voltage plates disposed in parallel of each other, and a high voltage rib which connects the plurality of high voltage plates. 8. The electric dust collector according to claim 7 , wherein the second electrode includes: a plurality of ground plates disposed in parallel of each other and the plurality of high voltage plates, and a ground rib which connects the plurality of ground plates.
