Abstract

PURPOSE:To eliminate shortcircuit discharge due to high voltage while facilitating the treatment of adhered dust, by providing electrodes to both surfaces of a each partition plate made of pottery and arranging a conductive filter element between adjacent partition plates. CONSTITUTION:Electrodes 2, 3 are provided to both surfaces of each pottery partition plate 4 and a filter element 1 such as metal wool comprising steel, Al or Cu or conductive plastic sponge is a lowed to fill the space between the electrodes 3, 3' with the same polarity of adjacent partition plates 4, 4'. When high voltage is applied between the electrodes 2, 3 by a DC high voltage power source 5, the filter element 1 contacted with the electrode 3 is held to the same potential as the electrode 3 and dust is adsorbed by electrostatic force generated between the filter element 1 and dust with potential of almost zero suspended in the air stream passing between the filter element 1 and the electrode 3. The filter element after use is drawn out between electrodes and disposed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electrostatic dust removal device, and more particularly to an electrostatic iron removal device in which there is no fear of short-circuit discharge due to high voltage and the filter material can be easily replaced.

(9E rice technology) ゛5! Apply a M electric field and remove fine dust with a silent electric power.
Electrostatic dust removal devices that remove deposits are widely used because they can remove finer dust than the pond method.

However, if the applied electric field is strengthened in order to increase the insect removal force t, the dust inspected by the vehicle becomes a discharge end and short circuits are likely to occur. ◎ (F!3υ purpose) This F8A has no fear of short-circuit discharge even if the applied voltage is increased, is resistant to layers, is easy to dispose of dust, and is cylindrical. Even when I try to use an electrostatic dust removal device that is hard to withstand, I am unable to do so.

(Invention v#1 kite) This 0 shot 1 is mw as shown in the O1 implementation sequence in Figure 1.
wL electric kettles 3 are provided on both sides of the partition plate 4 made of
．． Steel between 4 and 01iLII+3.3, At
The filter element 1 is filled with % Cu, etc., or isoelectric glass nac υ sponge. Then, a voltage υ^ is applied to the 11L 2.3 gate by the DC voltage source 5. The above device is stored in case 9,
Figure 2 shows another embodiment in which the airflow is caused to flow as shown by the arrow 8 in the figure. Lightly cross 1. A high voltage is applied between the electric currents 2 and 3 to cause the air flow 8 to pass through the filter element 1.

In both FIGS. 1 and 2, 6.7 is a terminal for voltage application.

(Operations and Effects) Since this invention uses the above-mentioned structure (1), [even if the vortex pressure is applied between Ik2 and 3, the ffl retainer existing in both the arashi-koshiki gates will still have insulation properties, Moreover, since the 11tl Arashi-Koshikuma K [dust does not come in contact with it], there is no risk of short-circuit discharge.

Then, the filter element that is in contact with liLtm3 is at the same potential as IIc 3, and the inside of it is 1Ih.
Almost zero electric potential floating in the airflow of t& ■ Adsorbs dust by electrostatic force generated between agricultural dust and zero. Also, when steel wool is used as the filter material, it chemically adsorbs S02, NOx, etc. In addition, the structure is concealed and simple, and each material has a high heat resistance of υ, which can be used in high mow environments. It has good durability and low cost.

Historically, the filter is simply inserted between the wires so as to make direct contact with the filter element tKFm3, so the historical theory is to draw this out and make it in advance as shown in Figures 3 (a) and (b). If the filter element you pull out is steel cool, even if you discontinue it, the paper will quickly deteriorate due to oxygen and moisture in the air, causing pollution. There's no fear.
