For example, WO2007/100254 illustrates a kind of particle capture device, and it is included in part makes the antenna-like object of the positively charged of air ionization, and attracts and collect the electronegative collecting board of ionic particles.The antenna of positively charged and electronegative plate produce electrostatic field above road, make it possible to remove flue dust, thin dirt and exhaust gas particle from the region of the generation electrostatic field of road top.

The shortcoming of this particle capture device is to remove relatively large contaminated particle.Ionic particles is only collided enough large particle.Contaminated particle is larger, and the probability of the ionic particles of motion and the collision of contaminated particle is just larger.

In addition, must produce relatively large electrostatic field and filter contaminated air.Required relatively large electrostatic field can cause relatively large institute's energy requirement and/or relatively large collecting board.This can cause negative effect to environmental problem, for example visual pollution and/or energy consumption.

Summary of the invention

The object of the invention is to eliminate problem above-mentioned or replacement scheme is at least provided.

Especially, the object of this invention is to provide a kind of particle capture device, it can remove relatively little contaminated particle from contaminated air.

This object can be reached for the particle capture device of catching particle from grain flow by according to claim 1.This particle capture device comprises first end and the second end.Preferably, supporting construction is made of metal.Particle capture device comprises the first charged wire emission electrode, and it has the first wire longitudinal axis, for make particle ionization in part.The first wire emission electrode is relatively sharp-pointed object, and the corona charging that it causes contaminated air is produced ionic particles.The first wire emission electrode remains between first end and the second end with tensioning state by supporting construction via insulator, and described insulator makes the first wire emission electrode and supporting construction electric insulation.The first wire emission electrode is elongated.Insulator makes the first wire emission electrode and supporting construction insulation, makes the first wire emission electrode can have the electrostatic charge different from supporting construction.In addition, particle capture device comprises spigot surface, in the plane vertical with the first wire longitudinal axis, guides at least a portion of grain flow for substantially.On the first direction vertical with the first wire longitudinal axis, spigot surface and the first wire emission electrode are spaced apart abreast.First direction is to limit along the minimum range between the first wire emission electrode and spigot surface.Spigot surface has the electrostatic charge different from the first wire emission electrode, for ionic particles being provided to the first electrostatic force towards spigot surface from the first wire emission electrode.The first electrostatic field providing towards spigot surface from the first wire emission electrode in the direction substantially the same with first direction is provided the first electrostatic force.Therefore, the first electrostatic force is substantially in the direction identical with first direction.Especially, this can cause grain flow to follow the track towards spigot surface.Especially, utilize positive electrostatic charge to make the first wire emission electrode charged, and utilize negative electrostatic charge to make spigot surface charged or make not static electrification lotus (for example,, in the time of spigot surface ground connection) of spigot surface.Positive electrostatic charge causes positive ionic particles.

Supporting construction also comprises the first longitudinal rod, and it is spaced apart abreast with the first wire emission electrode in the second direction vertical with the first wire longitudinal axis.Especially, longitudinal rod extends in the length that at least equals the first wire emission electrode.Second direction has the component contrary with first direction, this means to align with first direction but in the opposite direction.Second direction also has the component vertical with first direction.This means that the first wire emission electrode is arranged between spigot surface and the first longitudinal rod substantially.In other words, the first longitudinal rod separates with the first wire emission electrode and spigot surface.

Fig. 7 illustrates the perspective view of the particle capture device 1 of a third embodiment in accordance with the invention.Particle capture device 1 comprises the supporting construction 2 with first end 4a and the second end 4b.Here, supporting construction comprises the first structural detail 6a and the second structural detail 6b that lay respectively at first end 4a and the second end 4b.The first structural detail 6a and the second structural detail 6b are arranged to respect to ground perpendicular.Particle capture device 1 also comprises the first charged wire emission electrode 7, for make particle ionization in part.The first wire emission electrode 7a keeps tensioning by supporting construction 2 between first end 4a and the second end 4b.The first wire emission electrode 7a is elongated, and has the first wire longitudinal axis X1.It is upper that the first auxiliary rod 12a and the second auxiliary rod 12b are separately positioned on the first and second structural detail 6a, 6b, and wherein auxiliary rod 12a, 12b are provided with the first and second insulator 10A, 10B.The first wire emission electrode 7a keeps tensioning by insulator 10A, 10B, and wherein insulator 10A, 10B make the first wire emission electrode 7a and supporting construction 2 electric insulations.Auxiliary rod 12a, 12b are arranged to respect to ground substantial horizontal.This means that auxiliary rod 12a, 12b are arranged on the height substantially the same with vertical structural element 6a, 6b.The first wire emission electrode 7a also comprises spigot surface 15, for substantially guide at least a portion of grain flow S in the plane vertical with the first wire longitudinal axis X1.

Fig. 8 A is at particle capture device 1 shown in the plane vertical with the first wire longitudinal axis X1.On the first direction Z1 vertical with the first wire longitudinal axis X1, spigot surface 15 and the first wire emission electrode 7a are spaced apart abreast.First direction Z1 aligns with the minimum range between the first wire emission electrode 7a and spigot surface 15.Spigot surface 15 has the electrostatic charge different from the first wire emission electrode 7a for ionic particles being provided to the first electrostatic force.The first electrostatic force acts on ionic particles towards spigot surface 15 from the first wire emission electrode.The first electrostatic force derives from the first corresponding electrostatic field 30a producing towards spigot surface 15 from the first wire emission electrode 7a.The first electrostatic field 30a is substantially identical with first direction with the direction of the first electrostatic force of correspondence.At least, occurring the position of the first the strongest electrostatic field with the strongest first electrostatic force of correspondence, each has the direction substantially the same with first direction with power.

Supporting construction 2 comprises the first longitudinal rod 20a, and it is spaced apart abreast with the first wire emission electrode 7a on the second direction Z2 vertical with the first wire longitudinal axis X1.Second direction Z2 comprises the component contrary with first direction Z1.Second direction Z2 also comprises the component vertical with first direction Z1.This means, the first wire emission electrode 7a is arranged between spigot surface 15 and the first longitudinal rod 20a substantially.

The first longitudinal rod 20a has the electrostatic charge different from the first wire emission electrode 7a, and is suitable for ionic particles that the second electrostatic force that derives from the second electrostatic field 30b is provided.The second electrostatic force from the first wire emission electrode towards the first longitudinal rod 20a effect.The first longitudinal rod 20a is arranged so that the second electrostatic force is suitable for advancing grain flow S, while making to observe in the plane vertical with the first wire longitudinal axis X1, grain flow S follows at least in part around the ring-type track T1 of the first wire emission electrode 7a and the first longitudinal rod 20a.

As shown in the best in Fig. 8 A, the first electrostatic field 30a produces the first electrostatic force towards spigot surface 15 from the first wire emission electrode 7a in ionic particles.The second electrostatic field 30b produces the second electrostatic force towards the first longitudinal rod 20a from the second wire emission electrode 7 in ionic particles.The track of grain flow S represents with the dotted line of S instruction.

Moving particle in grain flow S is from the starting position setting in motion away from spigot surface 15, the first wire emission electrode 7a and the first longitudinal rod 20a, and flows to spigot surface 15.Moving particle is caught by the first electrostatic field 30a, and the first electrostatic force makes moving particle move to spigot surface 15, until its collision spigot surface 15.Because the component of second direction is vertical with first direction, moving particle boost at this Vertical Square due to ventilation (in other words, deflection).Ionic particles in the second electrostatic field 30b moves upward in second party, and indirectly attracts the particle around these ionic particles in substantially the same second direction.Attractive motion particle is called as ventilation.

Therefore, moving particle flows to the first longitudinal rod 20a from spigot surface 15.Moving particle can not collide the first longitudinal rod 20a, but can move along a curved path around the first longitudinal rod 20a due to ventilation effect, and described ventilation effect derives from grain flow S and flows to spigot surface 15 from starting position.

The existence of the first longitudinal rod 20a can produce carries out JP the second electrostatic field 30b of electricity to moving particle.

Like this, grain flow S comprises at least in part around the track of the first wire emission electrode 7a and the first longitudinal rod 20a circulation.

Fig. 8 B illustrates modified embodiment of the present invention, wherein the propelling of grain flow S is mechanically additionally produced by the first deflector face 25a.

The first deflector face 25a is arranged to spigot surface 15 spaced apart.In this case, the first deflector face 25a has bending member.Here, " spaced apart " expression first deflector longitudinal axis and spigot surface 15 are spaced apart.While observation, limit the first deflector gap 26a in this plane vertical with the first wire longitudinal axis X1.In the time that grain flow S collides the first deflector face 25a, at least a portion grain flow S follows the track through the first deflector gap 26a.At least another part grain flow S follows the track through the space relative with the first deflector gap 26a, is preferably oriented to the direction towards the first longitudinal rod 20a.Like this, grain flow S at least in part towards the first longitudinal rod 20a by mechanically-propelled, and be pushed into along spigot surface 15 at least in part.The former causes the first stronger ring-type track T1.The latter causes spigot surface 15 to collect more contamination particles.

Preferably, the first deflector face 25a is arranged on described position by supporting construction 2.

Preferably, the first collector 18A is arranged near spigot surface 15, to receive the particle from grain flow S.Preferably, make the first collector 18A with the electrostatic charge contrary with the electrostatic charge of the first wire emission electrode 7a.This is favourable, because grain flow S is attracted to the first collector 18A.Preferably, the first collector 18A is arranged on spigot surface 15, as shown in Figure 2 a.Further preferably, the first collector 18A be arranged near the first deflector gap 26a, grain flow S leaves the position of the first deflector gap 26a.Grain flow S then at least in part by the first deflector face 25a towards the first collector 18A mechanically-propelled.

For example, the first collector 18A is made up of electret.

Fig. 9 illustrates especially favourable modified embodiment, and wherein particle capture device 1 also comprises the second wire emission electrode 7b.The second wire emission electrode 7b has the second wire longitudinal axis X2, and between the first end of supporting construction 2 and the second end, keeps tensioning by the third and fourth insulator 10c, 10d.The second wire emission electrode 7b and the first wire emission electrode 7a are spaced apart abreast, limit the conductor spacing 28 between the first and second wire emission electrode 7a, 7b.Grain flow S follows the track towards spigot surface 15 through conductor spacing 28 at least in part.Spigot surface 15 and the second wire emission electrode 7b are spaced apart abreast on the third direction Z3 shown in the best in Figure 10 A.

In Figure 10 A, also illustrate that third direction Z3 aligns with the minimum range between the second wire emission electrode 7b and spigot surface 15 and along this minimum range.

Spigot surface 15 has the electrostatic charge different from the second wire emission electrode 7b, and is suitable for ionic particles that the 3rd electrostatic force is provided.The 3rd electrostatic force derives from the 3rd electrostatic field 30c producing towards spigot surface 15 from the second wire emission electrode 7b.

Except the first electrostatic field 30a, the 3rd electrostatic field 30c also cause grain flow S follow at least in part between conductor spacing 28 towards the track of spigot surface 15.

The second longitudinal rod 20b is arranged in supporting construction 2, and spaced apart abreast with the second wire emission electrode 7b on the fourth direction Z4 vertical with the second wire longitudinal axis X2.Fourth direction Z4 has the component contrary with third direction Z3.Fourth direction Z4 also comprises the component vertical with third direction Z3.Preferably, here, the component perpendicular to first direction Z1 of the component perpendicular to third direction Z3 of fourth direction Z4 and second direction Z2 is contrary and align.This is favourable, because the propelling for being provided by the first longitudinal rod 20a is added in the propelling being provided by the second longitudinal rod 20b synergistically.Can cause synergistically concuring by two longitudinal rod 20a, 20b are set like this, thereby produce than stronger the first ring-type track T1 and the second ring-type track T2 of situation only with two one in longitudinal rod 20a, 20b.

The 4th electrostatic force derives from the 4th electrostatic field 30d being produced by the second longitudinal rod 20b, and wherein the second longitudinal rod 20b has the electrostatic charge different from the second wire emission electrode 7b.Because the 4th electrostatic force is substantially on fourth direction Z4 and therefore comprise the component vertical with third direction Z3, so the second longitudinal rod 20b advances grain flow S to make grain flow S follow at least in part the second ring-type track T2 around the second wire emission electrode 7b and the second longitudinal rod 20b.

As shown in FIG. 10A, in the plane perpendicular to the second wire longitudinal axis X2, the first ring-type track T1 describes at least a portion of grain flow S along clockwise direction.The second ring-type track T2 is along different direction of rotation, and describes at least a portion of grain flow S in the counterclockwise direction.

Generally, the second longitudinal rod 20b, the second wire emission electrode 7b have advantages of identical with the layout of the first longitudinal rod 20a, the first wire emission electrode 7a and spigot surface 15 with the layout of spigot surface 15.But, these two is arranged to substantially be mutually symmetrical in the plane perpendicular to spigot surface 15 and is parallel to each other and can causes synergy between the first wire longitudinal axis X1 and the second wire longitudinal axis X2.The intensity of the first ring-type track T1 and the second ring-type track T2 can be stronger than the two situation arranged apart in the situation that of the two combination.This results from second direction Z2 has component contrary with fourth direction Z4 and that align and first direction Z1 and third direction Z3 and substantially points to same direction (although unjustified).

Figure 10 B illustrates that the second deflector face 25b and the second deflector gap 26b arrange with respect to the improvement of the first deflector face 25a and the first deflector gap 26a symmetry.Equally, the second collector 18B arranges symmetrically with respect to the first collector 18A.Identical advantage is applicable to the second situation of letter " b " instruction and the first situation of letter " a " instruction.

Figure 11 illustrates the modified embodiment corresponding to the 3rd embodiment of the situation of two wire emission electrode 7a, 7b and two longitudinal rod 20a, 20b.The first wire emission electrode 7a shown in figure and the second wire emission electrode 7b and the first longitudinal rod 20a and the second longitudinal rod 20b.Not shown but exist be according to spigot surface 15 of the present invention.

Particle capture device 1 also comprises the first voltage generator 40a, for providing particularly high voltage of voltage to the first wire emission electrode 7a and the second wire emission electrode 7b.Here, only the first voltage generator 40a supplies high voltage to wire emission electrode 7a, 7b, and is not supplied to longitudinal rod 20a, 20b.The first voltage generator 40a is configured to receiver voltage setting signal P1.Based on the value of voltage setting signal P1, the first voltage generator 40a provides corresponding voltage to the first wire emission electrode 7a.

Control module 35 is also shown in figure.Control module 35 is configured to provide voltage setting signal P1.Conventionally, control module 35, to voltage setting signal P1 assignment, makes to provide the voltage maintenance to the first wire emission electrode 7b constant.

The first longitudinal rod 20a is provided with the first bar electrode of insulation in supporting construction 2.By making the first longitudinal rod 20a be provided with the first bar electrode, allow easily to make the first longitudinal rod 20a charged.In replacement scheme, the first longitudinal rod 20a is identical with the first bar electrode.This is favourable because the first bar electrode be can be accurately charged surface, be also the structural elements providing support to particle capture device 1.

As mentioned above, the first electric field 30a produces towards the first longitudinal rod 20a from the first wire emission electrode 7a.This causes ionic bombardment the first bar electrode, makes generation current in the first bar electrode.Measure this electric current by the first current sensor 37a.The first current sensor 37a is configured to provide the first current measurement signal P2 of the electric current representing in the first longitudinal rod 20a.

It is constant that the first current measurement signal P2 does not keep in time, but conventionally change as shown in Figure 6.In the figure, the first current measurement signal P2 on vertical axis is shown as the function of the time on trunnion axis.

In the leftmost side of figure, the initial value of the first current measurement signal P2 is shown.The first current measurement signal P2 increases gradually.This is because little metallic particles, from the first wire emission electrode 7a scattering, increases the transmitting of the first wire emission electrode 7a, causes more charged ion.Along with first wire emission electrode 7a attenuation due to the little metallic particles of its scattering, the risk of the first wire emission electrode 7a fracture increases.

In order to reduce this risk and to extend life-span of the first wire emission electrode 7a, control module 35 is configured to receive the first current measurement signal P2 and controls voltage setting signal, the first current measurement signal P2 is held in substantially the same with the initial value of the first current measurement signal P2.

In addition, the increase of the first current measurement signal P2 being indicated by L1 represents the thickness of the first wire emission electrode 7a, and therefore represents its life-span.This information is particularly advantageous in the demand of user being indicated to preventive maintenance.

Particle in the first electrostatic field 30a causes the first current measurement signal P2 to reduce, and this is because ion and these particles in the first electrostatic field 30a collides and because ventilation is for example moved in the first ring-type track T1.

Therefore the amount of particle is caught in the representative that reduces of the first current measurement signal P2, being indicated by L2.This information is particularly advantageous in to user and indicates the grain amount of catching.It can easily provide about particle capture device is in the information of catching the efficiency aspect grain amount.
