Description

[0001] The present invention relates to an electrostatic precipitator,

The present invention relates to an electrostatic precipitator having improved dust collecting efficiency, and more particularly, to an electrostatic precipitator having an improved dust collecting efficiency, and more particularly, The electrostatic precipitator of the present invention can easily and quickly clean the dust collecting body after the dust collecting operation to remove foreign matter, and can improve the dust collecting efficiency of the foreign body by forming different electrodes on the dust collecting body. .

Generally, the electrostatic precipitator purifies contaminated air flowing in one direction and discharges the polluted air to the other side. The electrostatic precipitator includes a pre-filter, an ionizer, a dust collector, and an after filter.

Primarily, the prefilter removes dust of coarse particles in the contaminated air entering from the outside as a net structure by a simple physical method.

Then, the ionizing unit charges the fine particles in the neutron state, which have not been filtered by the pre-filter, with the "e +" or "e-" generated through the corona discharge caused by the application of the high voltage.

 Finally, the dust collecting unit includes a plurality of cell plates charged with '+' and '-' polarities, and collects and collects the fine dust charged in the ionization unit through the cell plate.

However, the above-described conventional electrostatic precipitator has a problem in that it can only remove dust in the air introduced from the outside, and is not capable of antibacterial, deodorization and decomposition of various harmful substances contained in the air.

In view of this, the electrostatic precipitator has been filed in the patent application No. 10-2006-0087822.

In general, the conventional electrostatic precipitator has a pre-filter formed in a mesh structure to primarily filter the particles in the air introduced from the outside, a plate-shaped earth electrode for charging fine dust in the air passing through the pre-filter, An ionization unit having at least one needle-shaped protrusion formed on both sides of the ionization unit, a discharge electrode formed on both sides of the ionization unit, and a plurality of dust-collecting cell plates for collecting charged fine particles passing through the ionization unit are alternately stacked, And an after filter for ultimately filtering the particles remaining in the air after passing through the dust collecting part. At least one or more spire-shaped bipolar projections are formed on the rear end of the discharge electrode.

However, in the conventional general electrostatic precipitator constructed as described above, the cell plate of the dust collecting part, which is provided for collecting the charged fine dust passing through the ionization part, is formed in a plate shape having a large surface area in order to increase the dust collecting efficiency , The entire width of the dust collecting unit is widened, and the cleaning of the cell plate of the dust collecting unit takes a long time.

In addition, since the cell plate of the conventional electrostatic precipitator as described above is formed of a plate having a large surface area in order to increase the dust collecting efficiency, warping occurs due to the wind power during blowing, There is a disadvantage that the dust collection efficiency is inferior.
