System forms spring oscillator, by vibrating the dust removed on four pairs of electrodes.
As shown in Fig. 2 (a), Fig. 2 (b), it is semicolumn housing to deposit dirt room, when the effect of spring motor ash-clearing structure is that cylinder is deposited
Storage structure is upward, and the dust on motor, which is fallen into, to be deposited in dirt room, and after deashing, the second stepper motor rotates 180 °, semicolumn
Concave surface storage organization go to it is following, prevent vehicle exhaust blow deposit dirt house dust exclude car outside pollute.
Convertor circuit is realized to be turned as the power supply of the 20kV HVDCs needed for 12V Vehicular direct-currents power supply to electrostatic precipitation
Change, its main process recommends convertor circuit through ZVS formula self-excitations for 12V and is changed into high-frequency ac, and high-frequency ac is through high frequency transformer liter
Buckling is high-voltage alternating, and rectification obtains required HVDC to high-voltage alternating again.Collecting electrode part is mainly completed in tail gas
The collection of grain thing, it is the place that highfield is concentrated.Collecting electrode is made up of 4 pairs of battery lead plates, and positive plate plate face is smooth, negative plate plate
Face is coarse, may make up severe non-uniform electric field.
Convertor circuit main body is actually that a two-tube auto-excitation type with ZVS recommends convertor circuit, and the 12V of input is straight
Rheology is changed to high-frequency ac, so that high-frequency step-up transformer is primary.Circuit operation principle is as follows：
Fig. 3 is the circuit topology figure, and when supply voltage acts on V+, electric current starts by the primary of both sides and to apply simultaneously
Onto MOS drain electrode (D).Voltage can simultaneously appear on MOS gate pole (G) and start to open MOS.Because without any two
Individual element is duplicate, and a MOS is faster than what another was opened, and more electric currents will flow through this MOS.
Opposite side MOS gate voltage is dragged down and begins to turn off it by the electric current by turning on side armature winding.It is electric in figure
Hold and primary inductance occurs LC resonance and voltage is changed by sinusoidal rule.If without this electric capacity, pass through MOS electric current
It can increase always, until transformer saturation even metal-oxide-semiconductor burns.Assuming that Q1 is first turned on.When Z point voltages follow the half of LC resonance
The individual cycle rises to peak value when returning again, and Y points voltage can be close to 0.Gate pole (G) voltage for dropping to 0, Q1 with Z point voltages disappears
Lose, Q1 is closed.Q2 is opened simultaneously, and now Y points voltage is begun to ramp up.
Z point voltage pull-downs to closely, this may insure that Q1 is complete switched off for Q2 conducting.Q2 completes the half cycle of LC vibrations
Same process can be repeated afterwards, and this oscillator continues cycling through work.In order to prevent this circuit from pulling huge peak value electricity from power supply
Flow and damage, add L1 and be used as buffering between V+ at transformer tapping.
Because metal-oxide-semiconductor condition of work requires higher, it is easily damaged, for example when gate source voltage is higher than 30V, metal-oxide-semiconductor will
It is breakdown and damage, it is therefore desirable to increase the protection circuit of metal-oxide-semiconductor, actual convertor circuit is as shown in Figure 4.
Wherein 470 Europe resistance are used for limiting MOS gate poles (G) electric current, prevent from damaging.10K resistance is used to ensure that MOS is reliable
Shut-off.The voltage of MOS gate pole (G) is limited within the breakdown voltage of voltage-regulator diode (12V) of selection by voltage-regulator diode.
High frequency transformer directly selects finished product high voltage package, due to coming with high voltage silicon rectifier stack inside it, it is possible to save whole
Stream part.High-frequency ac therein is boosted to about 20KV by its primary coil directly as the inductance of convertor circuit.
Due to the polar effect of electrostatic field, negative polarity pole non-uniform electric field corona inception voltage is relatively low, and breakdown voltage is higher,
So dust electric field is designed as negative polarity pole non-uniform electric field, i.e. positive plate plate face is smooth, and negative plate plate face forms tip.Design
Figure is as shown in Fig. 5 (a), Fig. 5 (b).
Electrostatic precipitator is a kind of efficient cleaner, and its principle is electrode is produced corona discharge using high-tension electricity,
Free electron and ion are released, makes grit charged, and electrically charged particle to dust polar motion and is collected by the effect of electric field force,
Realize gas solid separation.Electrostatic precipitator has lot of advantages, such as efficiency of dust collection is high, resistance is low, power consumption is few；Can efficiently it collect
Dust in big flow gas and high temperature or corrosive gas；Automaticity is high and maintenance is easy etc..
Innovation of the present utility model is that compensate for lacking soot dust granule clean lack in existing vehicle maintenance service
Point, while the works are a kind of Miniaturization Design based on high-pressure electrostatic precipitation principle device.The works are used for reference industrial staticelectricity and removed
Dirt principle, principle is simple, exhaust particulate good purification.By means of the development of present Power Electronic Technique, realize vehicle-mounted by 12V
Dc source is also relatively simple to HVDC.And the apparatus structure is simple, it is not necessary to expensive device, so having very big
Popularization and application space.
The application of high-pressure electrostatic precipitation industrially is bordering on complete, and the application in life, which but rarely has, hears of.Device is simple
Compact, space-consuming is few, can easily be applied to the processing of vehicle exhaust.Using the plasma of pulsed discharge, efficiently removing
Gas pollutant is removed while dirt.Compared with other kinds of deduster, electric cleaner has efficiency of dust collection high, up to 99%
More than.Regular maintenance expense is low, because attrition component and driving member are few, power consumption is low.
The preferred embodiment of the application is the foregoing is only, is not limited to the application, for the skill of this area
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent substitution, improvement etc., should be included within the protection domain of the application.
It is not new to this practicality although above-mentioned specific embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
