Definitions

  • This invention relates to dust collectors for collecting dust electrically charged in the air.
  • Electric dust collectors of electrostatic type are conventionally known that include an air passage, a charging part placed in the air passage and a dust collecting part placed downstream of the charging part (see Patent Document 1).
  • the electric dust collectors are configured to collect by adsorption dust in the air introduced into the air passage, thereby cleaning the air containing the dust.
  • the charging part of the electric dust collector positively charges the dust having flowed into the air passage.
  • the dust collecting part collects by adsorption the dust positively charged by the charging part.
  • the dust is separated from the air containing it to clean the air.
  • the dust collecting part in Patent Document 1 includes dust collecting electrodes formed in the shape of a flat plate and high-voltage electrodes of the same shape, wherein the dust collecting electrodes and the high-voltage electrodes are alternately arranged in parallel.
  • the dust collecting electrodes are grounded, while the high-voltage electrodes are connected to the positive side of a power supply provided in the electric dust collector.
  • a voltage is applied from the power supply, whereby a predetermined potential difference is created between each pair of adjacent high-voltage and dust collecting electrodes. Positively charged dust flows into the spaces where the predetermined potential difference is created, and is collected by adsorption on the grounded dust collecting electrodes.
  • Patent Document 1 Published Japanese Patent Application No. H01-310753
  • the resistance between each pair of adjacent dust collecting and high-voltage electrodes may drop to allow an excessive electric current to flow between the adjacent electrodes and thereby cause a spark (spark discharge). Furthermore, also when electroconductive powder dust is mixed in positively charged dust flowing into the dust collecting part, an excessive electric current may flow between the adjacent electrodes and thereby cause a spark. In short, when under normal operating conditions the resistance between the adjacent electrodes drops owing to some influence, a spark is caused between the electrodes.
  • the present invention has been made in view of the foregoing points and, therefore, an object thereof is to prevent the occurrence of spark between each adjacent electrodes in the dust collecting part while reducing deterioration in the dust collecting capacity of the dust collecting part.
  • a first aspect of the present invention is directed to a dust collector including: a charging part (12) for charging dust in the air with electricity; a dust collecting part (30) including a first electrode (40) and a second electrode (50) disposed near the first electrode (40); and a power supply for applying a voltage to the dust collecting part (30).

  • the first electrode (40) is made of an electroconductive resin.
  • the first electrode (40) is constituted as a dust collecting electrode (40) for collecting the charged dust by adsorption.
  • the grounded first electrode (dust collecting electrode) (40) is made of an electroconductive resin, the volume resistivity of the dust collecting electrode (40) can be increased as compared to, for example, electrodes made of metal.
  • a second aspect of the invention is the dust collector according to the first aspect of the invention, wherein the volume resistivity of the electroconductive resin is 10 8 ⁇ cm to 10 12 ⁇ cm, both inclusive.
  • the volume resistivity of the electroconductive resin since the volume resistivity of the electroconductive resin is specified, a predetermined volume resistivity can be given to the dust collecting electrode (40) constituting the first electrode.
  • the volume resistivity of the electroconductive resin if the volume resistivity of the electroconductive resin is too low, the electroconductive resin loses resin characteristics, thereby easily causing a spark.
  • the volume resistivity of the electroconductive resin is too high, the mobility of charges within the dust collecting electrode (40) upon approach of dust is decreased. Therefore, the mobility of charges to the surface of the dust collecting electrode (40) is decreased, resulting in a significantly deteriorated dust collecting capacity of the dust collecting part (30).
  • the dust collecting electrode (40) can be constituted as an electrode that reduces deterioration in the dust collecting capacity of the dust collecting part (30) while maintaining its resin characteristics.
  • a third aspect of the invention is the dust collector according to the first or second aspect of the invention, wherein the second electrode (50) connected to the positive side of the power supply is made of an electroconductive resin and the volume resistivity of the electroconductive resin is 10 3 ⁇ cm to 10 8 ⁇ cm, both inclusive.
  • a predetermined volume resistivity is given not only to the dust collecting electrode (40) but also to the second electrode (high-voltage electrode) (50) connected to the positive side of the power supply.
  • respective suitable volume resistivities for the dust collecting electrode (40) and the high-voltage electrode (50) can be set within the ranges of volume resistivities of respective electroconductive resins for the electrodes (40, 50).
  • a fourth aspect of the present invention is directed to a dust collector including: a charging part (12) for charging dust in the air with electricity; a dust collecting part (30) including a first electrode (40) and a second electrode (50) disposed near the first electrode (40); and a power supply for applying a voltage to the dust collecting part (30).
  • the charging part (12) of the dust collector includes a charging means (12a) for negatively charging the dust.
  • the first electrode (40) is grounded and the second electrode (50) is connected to the negative side of the power supply.
  • the first electrode (40) is made of an electroconductive resin.
  • the grounded first electrode (dust collecting electrode) (40) is made of an electroconductive resin, the volume resistivity of the dust collecting electrode (40) can be increased as compared to, for example, electrodes made of metal.
  • a fifth aspect of the invention is the dust collector according to the fourth aspect of the invention, wherein the volume resistivity of the electroconductive resin is 10 8 ⁇ cm to 10 12 ⁇ cm, both inclusive.
  • the volume resistivity of the electroconductive resin is specified, a predetermined volume resistivity can be given to the dust collecting electrode (40).
  • a sixth aspect of the invention is the dust collector according to the fourth or fifth aspect of the invention, wherein the second electrode (50) connected to the negative side of the power supply is made of an electroconductive resin and the volume resistivity of the electroconductive resin is 10 3 ⁇ cm to 10 8 ⁇ cm, both inclusive.

Therefore, even if the resistance between the first electrode (40) and the second electrode (50) drops owing to some influence, it can be prevented that an excessive current flows between the electrodes. Thus, the occurrence of spark can be prevented without reducing the voltage applied from the power supply below a predetermined value or increasing the distance between the electrodes above a predetermined value.

  • the electrodes (40, 50) in giving volume resistivities to the electrodes (40, 50) of the dust collecting part (30), the electrodes (40, 50) can be independently given their respective volume resistivities. Therefore, the occurrence of spark can be prevented while the flexibility of configuration of the electrodes (40, 50) can be increased.
  • the volume resistivity of the first electrode (40) can be increased by making the first electrode (40) from an electroconductive resin. Therefore, even if the resistance between the first electrode (40) and the second electrode (50) drops owing to some influence, it can be prevented that an excessive current flows between the electrodes (40, 50).
