Technical field
The invention belongs to technical field of air purification, and in particular to a kind of air purification method based on external electromagnetic field.
Background technology
Increasingly serious with air pollution problems inherent, people are more and more universal to the demand of air purifier so that market
On air purifier sales volume rise year by year.For primary air clarifier at present on the market, they mainly remove air
In pollution particulate matter, such as PM2.5 and other pollute dusts.Its air purifying process used mainly has adsorption technology, work
Property oxygen technology, electrostatic precipitator technology, anion technology and filtering technique etc..These technologies be mainly characterized by will pollution particle inhale
It is attached or make pollution aggregation of particles settle, and then reach purification air effect.Traditional air purifier, its essential core part is
Screen membrane, particle filtering will be polluted by screen membrane.This screen membrane that fully relies on is made a return journey the air purifier of depollution particle,
Higher is required to screen membrane.And due to screen membrane restricted lifetime, it is necessary to frequently change screen membrane, the later stage use cost of clarifier
It is higher.
Present air purifier on the market, core component is also added into other pollution particles and removed in addition to screen membrane
Module (such as anion generator, electrostatic precipitator).This kind of air purifier, early stage first settles partial contamination particle, the later stage
Filter screen membrane filtration is carried out again.For example, for anion generator, it can generate anion, first make the partial contamination in air
Focusing particles are settled, and are then again filtered residual contamination particulate matter with screen membrane.This is to a certain extent, it is possible to increase filter
Nethike embrane service life.But, there is the too low defect of pollution particle early stage sedimentation rate in this kind of air purifier, still there is filter screen
Film changes the problems such as frequent and small pollution particulate burning purifying is not thorough, causes clarifier later stage use cost height, clean-up effect big
Give a discount.
The content of the invention
(such as conventional purge device is not thorough to molecule purification, and the later stage is run into view of the shortcomings of the prior art by the present invention
This height, lacks man-machine interaction etc.), one kind is proposed based on external electromagnetic field to ionize pollution particulate matter and change Particles Moving track
Air purification method.The core technology of the present invention is utilization space electromagnetic field, positively charged pollution particulate matter is spinned motion,
Holdup time of the pollution particle in clean room is increased with this, the collision probability of pollution particulate matter and anion is improved, makes generation
The pollution particle of collision assembles sedimentation in clean room, improves the sedimentation rate of pollution particle.The use of the present invention, can effectively be carried
The sedimentation rate of high pollution particulate matter, improves the service life of screen membrane, the later stage use cost of air purifier is reduced indirectly.
And the present invention can make small pollution particulate burning purifying obtain more thorough, improve the clean-up effect of clarifier.Air proposed by the present invention

With the life-span, the later stage use cost of air purifier is reduced.
To achieve these goals, the present invention is as described below using technical scheme：
The external electromagnetic field of the present invention is divided into electric field and magnetic field two parts.There are a variety of generation schemes, this hair in electric field and magnetic field
Bright suggestion generates electric field with a pair of electrically opposite powered conductive fabrics, and magnetic field is generated with hot-wire coil.It is electrically opposite by a pair
Powered conductive fabric is arranged on formation electric field in clean room two ends, now clean room two ends oppositely charged, clean room, and direction is from one
Point to the other end in end.In clean room, outer layer is uniform close around hot-wire coil so that magnetic field is generated in clean room.At this moment, in clean room
It is dispersed with electromagnetic field.Clean room, installed in purification chamber interior walls centre position, makes purification indoor distribution built with anion generator
There is anion.Air enters from clean room positively charged end so that pollution particle positively charged.The pollution particle of positively charged will be by electricity
The effect of field force, because suffered electric field force is far longer than its gravity, therefore particle will do uniformly accelrated rectilinear motion, and direction is from purification
Room positive terminal is to negative electricity end.To during clean room's negative electricity end motion, positively charged pollution particle can be with the band that is dispersed with clean room
Anion collision, the aggregation of opposite-sign, are finally settled down to purification chamber interior walls, realize the purification of air.Air after purification from
Clean room negative electricity end is discharged, and the positively charged that does not settle before pollution particle can be electrically neutralized, therefore will not discharge and have to human body
Harmful positively charged particle.
If positively charged pollution particle is only acted on by electric field force, it is uniformly accelrated rectilinear motion that it, which is moved, in clean room
The interior holdup time is short, and movement locus coverage is small.And the negative ion concentration for purifying indoor distribution is limited, cause many pollutions
Grain can not collide in whole motion process with anion, also can not just assemble sedimentation, clean-up effect is undesirable.Clean room
There are problems that of middle space magnetic field solves this.The charged particle of motion can be by magnetic field force in magnetic field, and institute is magnetic field force induced
Move direction vertical, do not change its movement velocity, but its direction of motion can be changed.Therefore, pollution particle is made using electric field
Certain initial velocity is produced, particle motion is changed using magnetic field, both coordinate, with regard to particle can be made to be changed into doing spiral shell from linear motion
Rotation motion.Particle is moved in clean room's inside spin, and the other end is moved to from one end, and whole process substantially prolongs particle in purification
The indoor holdup time, add the probability that particle is collided with anion so that more pollution particles are in purification indoor settlement.Especially
It is directed to small particles of pollution thing, the linear motion compared to before, and screw makes probability that it collides with anion significantly
Increase, small particles of pollution thing sedimentation rate is greatly improved.
The present invention technical spirit be：
By the direction for setting electric field and magnetic field so that the pollution particle of positively charged is spinned motion in clean room, is carried
The high probability that it collides with anion, so as to improve the sedimentation rate of pollution particle.As for specifically how setting electric field and magnetic
Field direction, has a variety of methods to realize, which kind of implementation is the present invention be not specifically designated.In embodiments herein
In, the present invention describes a kind of embodiment in detail, can be for reference.
The present invention has the beneficial effect that：
The present invention, which can make largely to pollute particle, is deposited in purification chamber interior walls.In air after purification, do not sunk containing minority
The pollution particle of drop, the later stage can further be purified with screen membrane.Because most of pollution particle is by sedimentation side
Formula is purified, and later stage screen membrane needs the amounts of particles purified to greatly reduce, and this provides for improved screen membrane service life, reduction is net
Change device later stage operating cost.And the present invention is obvious for small particles of pollution thing clean-up effect, clarifier can be improved dirty to little particle
Contaminate the detergent power of thing.

Any formal limitation is done in invention.
Fig. 1 is one embodiment reference of the inventive method, this more than one embodiment of embodiments of the present invention.Ginseng
Method proposed by the present invention, lower mask body introduction can be realized by examining Fig. 1.
For the description specific embodiment of the invention, the present embodiment comes simulated air clean room with circular cylindrical cavity.The present invention
The electromagnetic field being related to can be divided into electric field and magnetic field two parts, and electric field is produced by the conductive fabric of a pair of oppositely chargeds, magnetic field by
Hot-wire coil is produced.Anion generator is housed inside cylindrical cavity.As shown in figure 1,1 is circular cylindrical cavity, 2 for it is uniform it is close around
In the coil of cylindrical cavity outer layer, coil winding direction is vertical with horizontal direction.3 be the anion generator of inside cavity.It is empty
Gas enters cavity from 1-2 ends, is purified in inside cavity, and the air after purification is excluded from 1-3 ends.
The present invention is to the material of cavity 1, the material of the powered cloth in cavity two ends, the specification of coil 2, anion generator 3
Specific species etc. does not do considered critical, and these are not belonging to core technology essence of the present invention.
With reference to Fig. 1, the embodiment of the present invention is discussed in detail.
Step one：Two pieces of conductive fabrics are installed at the two ends of cylindrical cavity so that 1-2 sections of positively chargeds, 1-3 ends are negatively charged.
Step 2：Anion generator 3 is installed in inside cavity.The present embodiment is not strict with 3 particular location, still
It is recommended that being installed in cavity top location roughly halfway up.
Step 3：Uniform close around one group of hot-wire coil 2 in cylindrical cavity outer layer, winding direction is vertical with horizontal direction.
In step one, inside cavity can form the positive electric field of horizontal direction, and direction of an electric field points to 1-3 ends by 1-2 ends.When
Air is from 1-2 ends after positively charged conductive fabric enters cavity, and pollution particle in air is by positively charged.The pollution of positively charged
Grain can be moved in the presence of electric field to 1-3 direction.
In step 2, anion generator work makes to be full of electronegative anion in cavity.The pollution of positively charged
Grain is with being distributed in the anion with opposite-sign in cavity, it may occur that collision, aggregation, sinking so that pollution particle is settled down to chamber
Inwall below body.Residue fails the pollution particle of aggregation sedimentation, in conductive fabric negatively charged by 1-3 ends, its own institute's band
Positive electricity can be neutralized, from cavity discharge.
Positively charged pollute particle in the presence of electric field, can by horizontal direction electric field force, because its gravity is much small
In the electric field force being subject to, therefore the uniformly accelerated motion that its motion in the electric field can approximately horizontally.This causes pollution
Grain movement locus in cavity is straight line, and the holdup time is shorter.Ultimately result in that pollution particle and anion collide is several
Rate is low, and sedimentation rate is relatively low, and clean-up effect is undesirable.For small particles of pollution thing, due to itself small volume, with bearing
Ion collides, and probability is lower, and clean-up effect is worse.Step 3 exactly solves this defect and set.
In step 3, hot-wire coil 2 can produce magnetic field inside cylindrical cavity.According to biot savart's law, (I is logical
Electric coil current strength, R is the space length apart from hot-wire coil)：
Understand that the magnetic field in cylindrical cavity can be similar to uniform magnetic field.It is now assumed that the uniform magnetic field in cylindrical cavity is：One it is positively charged be q, quality be m pollution particle, due to the effect of electric field force, it is assumed that in cylindrical cavity
Initial velocity isAs shown in Fig. 2 handleDecompose speed horizontallyWith the speed of vertical directionMagnetic field is to this
Pollution particle active force be：
It follows that pollution particle withAlongDirection moves with uniform velocity, and verticalThe plane in direction is made at the uniform velocity
Circular motion.The radius of its circular motion is tried to achieve by below equation：
Consider further that electric field force of the pollution particle by horizontal direction, it is known that it does acceleration linear motion in the horizontal direction,
Vertical direction does uniform circular motion.Comprehensive two type games, it is known that the pollution particle of positively charged makees helix in cylindrical cavity
Motion, its movement locus is substantially as shown in Figure 3.
With reference to above-mentioned proof.The pollution particle of positively charged, can be in inside cavity from 1-2 in the presence of magnetic field and electric field
Section is for the helical movement to 1-3 ends.The screw of particle, substantially prolongs its holdup time in inside cavity, add
The spatial dimension that grain movement locus is covered.So as to substantially increase positively charged pollution particle and the anion of distribution in cavity
Collision probability so that more pollution particles are deposited in inside cavity.
The introducing of space magnetic field so that pollution particle is spinned motion, substantially increases the sedimentation rate for polluting particle.Especially
For small particles of pollution thing, its probability collided with anion in cavity is added, is improved to small particles of pollution thing
Clean-up effect.
As described above, the present embodiment main working process is：Unpurified air enters from cavity one end to pollute particle
Positively charged, under spatial electromagnetic field action, pollution particle is spinned motion to the cavity other end, will be with being distributed in chamber during this
The anion in internal portion collides and settled.Air after purification is discharged from the cavity other end, is necessarily contained in the air of discharge
There is a small amount of be not cleaned completely to pollute particle, it is proposed that the later stage can further be purified by modes such as screen membranes.
The use of the present invention can significantly improve the sedimentation rate of pollution particle so that more pollution particles can be with sedimentation
Mode be cleaned.In this way, remaining amounts of particles for failing sedimentation is also considerably reduced, this, which allows for later stage screen membrane, needs filtering
Pollution amounts of particles reduce, the service life of screen membrane is improved indirectly, reduce the operation of later stage air purifier into
This.And the present invention is environmentally friendly, will not produce any harmful substance.
It is described above, be only presently preferred embodiments of the present invention, any formal limitation not done to the present invention, it is every according to
According to the present invention technical spirit above-described embodiment is made any simple modification, equivalent variations, each fall within the present invention protection
