Description
Technical field
Patent of the present invention belongs to electronic applications, refers in particular to a kind of non-linear magnetic field generator.
Background technology
The fire coal that Thermal Power Enterprises, heating enterprise are used is one of important sources of PM2.5, thus to these enterprises
The improvement of emission is the important means of suppression PM2.5.In numerous administering method electrostatic be one more
Preferably method.Electrostatic precipitation, mainly by charging particle, is then adsorbed and removes.Although this is a kind of
Good way, but the clearance for molecule can't reach satisfaction, this is because kinetics
Diameter granule near 1 micron is difficult to charged, because electric charge do not gone up by granule band, so can not be by electric field pole
Plate adsorbs.For this at the clearance of granule, the most significantly increase windage, need to take measures further
.On the basis of electrostatic precipitation, magnetic field is increased for this.Charged particle can produce complexity under the influence of a magnetic field
Rameau moves so that charged particle is increased resident time in processing electric field.Researcher is had to be placed in by Magnet
In high-voltage electrostatic field, thus add magnetic field in being formed, but Magnet increases the biggest windage in electrostatic field.With
Shi Caiyong permanent magnet poles is fixing makes charged particle time of staying in electric field fall short of, and uses alternation
Magnetic field can make charged corpuscle stop the longer time at electric field.
Using alternating magnetic field that dust removing effects can be made more preferable, but bring a problem simultaneously, alternating magnetic field can increase
Add electromagnetic pollution, i.e. produce stronger electromagnetic interference (E1ectromagnetic Interference
EMI), so that whole equipment can not meet the requirement of relevant Electro Magnetic Compatibility (EMC) standard.In recent years by
In various electrically, the sharply increasing of number of electronic devices, make the attention being increasingly subject to people of equipment room.
The European Community it has been specified that, from 1 day January in 1996, entered the electronics in European Community market, electric product must accord with
Close relevant EMC standard, otherwise circulate not in European market.In order to avoid reducing the same of atmospheric pollution
The generation of the difficult situation of Shi Zengjia electromagnetic pollution, reducing electromagnetic interference is a very important condition.?
Document report is had to utilize chaos can effectively reduce electromagnetic interference.In sum, it is possible to produce chaos magnetic intensity
Equipment will may be used for the eliminating equipment to microparticle (aerosol).Have not yet to see this type of special equipment
Report.
Patent of the present invention proposes a kind of non-linear magnetic field generator, and it can increase effectively to microparticle (gas
Colloidal sol) clearance.
Summary of the invention
In order to not only promote the clearance of microparticle but also reduce electromagnetic interference, the present invention proposes a kind of nonlinear magnetism
Field generator.
Patent of the present invention solves the technical scheme is that present invention of its technical problem by single-chip microcomputer, digital-to-analogue
Modular converter, audion, ferrite, coil, resistance, electric capacity form, and it is characterized in that: single-chip microcomputer (1
) by D/A converter module (2), resistance (R1), electric capacity (C1), audion (3), same to coil
(5) being connected, coil (5) is wrapped on ferrite (4), and coil (5) is by the same electricity of electric capacity (C2)
Resistance (R3) is connected, and the same resistance of the colelctor electrode (R3) of audion (3) is connected, the base stage of audion (3)
Same resistance (R2) is connected.
It is to apply to compare the most non-linear chaos signal generator, its kinetics side that Logistic maps
Journey is Xn+1=aXn(1-Xn)
It is an algebraic equation, has two variablees: independent variable X and parameter a, for independent variable X, be two
Secondary algebraic equation.Owing to normalization X is between 0 to l, value, between 0 to 4, presents when wherein taking 3.58 to 4
Chaos state.Calculating its Lyapunov exponents is about 0.6929, and more than zero, Theoretical Calculation shows now
Signal is in chaos state, and the cross correlation for two sequences is little close to 0, and the signal of output has good
Good aperiodicity continuous wide band frequency spectrum white noise character, shows that Logistic mapping has good reduction electricity
Magnetic disturbance.
When programming, Logistic mapping parameters a=4,0 < x < 1.Logistic is mapped and is changed,
Random sequence takes advantage of FFFFH again so that it is become the l6 position binary sequence between 0～FFFF, will former little number sequence
Row return FFFFization, and single-chip microcomputer can carry out effective data process.Logistic after deformation maps and develops into
Xn+l=4Xn(FFFF-Xn)/FFFF
Now, 0 < x < FFFFH.To an initial value X0, by single-chip microcomputer, utilize intervalometer 1 often to produce and once interrupt
Realize an iteration, produce a digital signal, 16 binary sequences produced according to this formula be exactly with
Machine sequence, its probability distribution meets normal distribution, and this random sequence is assigned to the timing constant T1 of intervalometer,
Numeral needed for D/A conversion measures the least-significant byte of this random sequence.
The chaotic signal that single-chip microcomputer produces, is exported by port and is sent to D/A converter module.Through digital-to-analogue conversion
Digital signal dress is changed to analogue signal by module, is sent to be wound on ferrum after resistance, electric capacity, audion amplify
Coil on oxysome, can produce the magnetic field that magnetic field intensity is chaos change in coil, and at ferritic work
With convergence.
Patent of the present invention provides the benefit that, not only can promote the clearance of microparticle but also reduce electromagnetic interference,
To reach the optimum efficiency of dedusting.It is mainly used in electrostatic precipitation field.
