Five, the specific embodiment

Fig. 3 is an air cleaning unit schematic perspective view produced according to the invention; Fig. 4 is the A-A profile of Fig. 3; Fig. 5 is in the air cleaning unit produced according to the invention, shows the profile of electronics moving direction and direction of an electric field; Fig. 6 is in the air cleaning unit produced according to the invention, with induction level, removes the clearance figure of nitrogen oxide (NOx).

Air cleaning unit of the present invention as shown in Figure 3.Pair of plates type cathode electrode (10) is installed mutually in the other direction.Between this target electrode (10), insert mutual isolate, plate magnetic force generating means (40).Make linear electrode-anode electrode (20) connect magnetic force generating means (40).A pair of cathode electrode (10) and anode electrode (20) and device for generating voltage (30) [high voltage has permissible value] constitute air cleaning unit of the present invention.

At this moment, between a pair of cathode electrode (10) and anode electrode (20), to form an electric field in order making, and to form a magnetic field, at a length direction insertion magnetic force generating means (40) of cathode electrode in the vertical direction of electric field.Magnetic force generating means (40) position, the two poles of the earth of being inserted should meet the N utmost point and S utmost point status requirement.

And magnetic force generating means (40) is that a plurality of flat poles are isolated into palisade with certain interval mutually.The magnetic force generating means should have through hole on (40), and anode electrode (20) is run through.The diameter of this through hole is generally decided by the insulation condition that forms between anode electrode (20) and the magnetic force generating means (40).

And the N utmost point and the S utmost point of magnetic force generating means (40) should be along its length, and flat pole should vertically be provided with, and the magnetic induction intensity (B) that the magnetic force generating means is had has determined dull and stereotyped thickness.

Because flabellum is in rotation, between flat pole and flat pole, axially, revolving force makes and flows into the air that contains pernicious gas in the air cleaning unit.

And the distance between this anode electrode (20) and the cathode electrode (10) should be with the same or smaller in the past, and the size of electric field also should be with the same in the past, and the voltage that allows between two electrodes is also identical.

Equally, in the air cleaning unit that magnetic force generating means (40) are housed, (10) and anode electrode (20) allow high voltage from the device for generating voltage to the cathode electrode.And an end of air cleaning unit can suck gas (as shown in Figure 4).With anode electrode (20) is the center, forms certain strength electric field (E) from cathode electrode (10) to anode electrode (20).

Meanwhile, magnetic force generating means (40) is owing to electric current produces magnetic field, perhaps according to permanent magnet from the S utmost point to the N utmost point, both the direction of the opposite utmost point forms the magnetic induction intensity (B) with certain intensity mutually.

Promptly form electric field (E) in vertical direction, horizontal direction forms magnetic induction intensity (B), because high-pressure energy makes the surperficial ejected electron of this cathode electrode (10) (e).

But as shown in Figure 5, electronics (e) not only is subjected to the influence in the magnetic field parallel with electrode, but also is subjected to from anode electrode (+) (20) to the formed electric field influence of cathode electrode (-) (10).Electronics (e) is not done with direction of an electric field is reciprocal and is moved both vertically in electric field (E), and by the circular motion of making a concerted effort to do of magnetic induction intensity (B) and electric field (E).

Be that electronics (e) rotates simultaneously in the space of magnetic induction intensity (B) and electric field (E), move to anode electrode (+) (20) direction.

At this moment, in the space of magnetic induction intensity (B) and electric field (E), the suffered power of mobile electron (e) can be represented with [mathematical expression 1].

[mathematical expression 1]

$\mathrm{Fa}=m-\frac{\mathrm{dv}}{\mathrm{dt}}-e(\stackrel{\→}{E}+\stackrel{\→}{\mathrm{\υ}}\×\stackrel{\→}{B})$

[mathematical expression 1] expression, magnetic induction intensity (B) power that mobile electron (e) is suffered and electric field (E) power, e is an electronics,

Expression electric-field intensity, The electronics translational speed, Expression magnetic induction intensity.

Promptly on the one hand, electronics (e) is subjected to move according to movement locus and particle moving direction in the electric field force effect; Magnetic field force induced work is as garden Zhou Yundong on the one hand, and the two is synthetic, does the orbiting motion of similar circular arc.

Thus, the movement locus of electronics (e) becomes arc by straight line, has prolonged the distance that moves in the electrode, so this electronics (e) also increases with collision frequency between the gas molecule of existence between the cathode electrode (10).

Between cathode electrode and anode electrode, when being added with high voltage [permissible value is arranged], free electron that quickens fast in electric field and the gas molecule collision between the electrode make gas molecule ionization, owing to increased collision frequency, quickened the ionization of gas molecule.

Isolate more polyelectron in the ionized gas molecule, these electronics have quickened plasma (Plasma) state of gas molecule again, and more gas molecule is being enriched under the cooling Power effect on the cathode electrode (10).

In low temperature plasma (Plasma) state, ion temperature is a low temperature, and electron temperature is a high temperature, because electron motion is dialled than ion motion is alive, has increased the electronics motion track, has increased the ionization quantity of gas simultaneously.

As shown in Figure 6, in the size of magnetic induction intensity with remove in the chart of pernicious gas relation as can be seen the magnetic induction intensity of x axle on electrode, determining, the remove rate of y axle for removing nitrogen oxide (NOx).

Magnetic induction intensity in magnetic field (B) is under zero the situation, only to remove nitrogen oxide (NOx) finite concentration.But behind the formation magnetic field, magnetic induction intensity (B) is big more, and it is many more to remove pernicious gas, and the rate of removing increases.

When magnetic induction intensity (B) reached 1600 Gausses (Gauss) left and right sides, the rate of removing of nitrogen oxide (NOx) reached saturation point; When 3000 Gausses (Gauss) were above, the rate of removing of nitrogen oxide (NOx) presented downward trend on the contrary.

But, to compare with the situation that does not allow magnetic field, when allowing to have an appointment 2000 Gausses (Gauss) magnetic field, the left and right sides, the rate of removing of nitrogen oxide (NOx) increases about 20%.

The main cause that the rate of removing of nitrogen oxide (NOx) increases is only to do on the electric field straight-line electronics, because the cause of complementary field also rotates simultaneously, increased the distance of electron motion, increased relatively and gas collisions number of times, the phenomenon that is occurred.

That is to say that the needed area of magnetic force generating means (40) is exactly that minimum magnetic induction intensity reaches the above area of 1000 Gausses (Gauss).
