Detailed description of the invention

Remove haze device below in conjunction with drawings and Examples to a kind of electrostatic described in the utility model to be described in detail.

As shown in Figure 1, a kind of electrostatic of the present utility model is except haze device, and described device comprises: field generator 1 and dust arrester 2; Described field generator 1 produces high-voltage electrostatic field, for the tiny dust in absorbed air by the driving of power supply; Described dust arrester 2 is for removing the dust of accumulation in field generator 1.

Electrostatic based on said structure removes haze device, and the electrostatic high-pressure that described power supply can adopt high voltage source to provide drives field generator 1.Described dust arrester is a dust sweeping device, its one or more sweep-up pipe by being provided with, uses the principle of dust catcher to be sucked in field generator 1 by dust.

The step utilizing above-mentioned electrostatic to carry out indoor dedusting except haze device is:

First, employing high voltage source provides the high tension voltage needed for electrostatic field; Then under the effect of the high direct voltage voltage of high voltage source, in described field generator 1, form uniform electrostatic field, utilize this electrostatic field to adsorb by the dust in the air of this electric field; When dust granule now passes through in high voltage electric field, due to negative electrode generation corona discharge, gas is ionized.Electronegative gas ion is anode motion under the effect of electric field, collides at the volley, make negative electricity on dust granule band with dust granule.Dust granule after charged is under the effect of electric field, and also anode motion, the dust be thoroughly separated with air is then deposited on anode, and it is outside that the air be purified then is discharged field generator 1.Finally, after dust accumulation to a certain extent, collected in a closed container by dust arrester.

As shown in Figure 2, suppose to have that a length is L, width is b, be highly the rectangular channel of d, upper plate (negative electrode), the lower plate (anode) of this passage are connected with the high-voltage DC power supply of voltage constant.The dust that quality is m, the quantity of electric charge is-q, be evenly distributed is with horizontal velocity v ₀enter rectangular channel, the distance of this charged dust and lower plate is d ₀, after electronegative dust encounters lower plate (anode), its institute is electrically chargedly neutralized, simultaneously by dust arrester from collected by this lower board surface.

Now, charged particle enter move in electric field time, distance lower plate distance be d ₀.If the voltage of high voltage source is U, have in the horizontal direction:

L＝v ₀t

Have in vertical direction:

$d_0=\frac{1}{2}{\mathrm{at}}^2$

From Newton's second law:

$a=\frac{F}{m}$

Wherein, electric field force F can be expressed as:

F＝qE

Electric field strength E can be expressed as:

$E=\frac{U}{d}$

Therefore, charged dust is met by the condition of adsorbing:

$d_0=\frac{1}{2}\frac{qU}{dm}{\left(\frac{L}{v_0}\right)}^2$
