Description

A kind of intelligent automatic adjustment work dot system of high voltage power supply
【Technical field】
The present invention relates to the technical field of electronic technology and environmental protection industry (epi), the intelligent automatic tune of particularly a kind of high voltage power supply The technical field of section work dot system.
【Background technology】
Increasingly serious with domestic air pollution, the demand of control atmosphere pollution is increasingly urgent, air is administered at present dirty Contaminate using it is most be high pressure electrostatic precipitation technology.Its principle is:High voltage power supply produces the high direct voltage of tens thousand of volts and is applied to collection Electrostatic highfield is formed on the pole plate of dirt electric field, negative high voltage discharge electrode launches a large amount of negatively charged electronics simultaneously.Dust, oil smoke etc. Negative electrical charge is taken when pollutant is by clarifier dust electrostatic field, is caught by electric field force be adsorbed onto on positive plate immediately, go decontamination The pure air of dye thing is discharged into again in air, so as to the purification for realizing pollution sources is controlled.Can effective process dirt using the technology The dust and oil smoke in dye source, prevents from polluting air, and power plant, industrial and mining enterprises and catering trade are widely used at present, It is the mainstream technology of control atmosphere pollution, application surface is increasingly extensive.
But, it is exactly cannot to be all the time in best operating point, Jing in place of current high pressure electrostatic precipitation technology still has some deficits Often in over-voltage breakdown discharge condition or under-voltage condition, cause clean-up effect undesirable.
In order to improve clean-up effect, the higher the better for the high pressure of high-voltage electrostatic field, but too high voltage easily occurs high-voltage breakdown Electric discharge, the electric-field intensity for causing electrostatic field is fallen, and triggers high voltage power supply protection act closing High voltage output so that dust removing effects It is undesirable;, whereas if reducing output high pressure, although do not have disruptive discharge situation, clarifier dedusting stability is improved, but is purified Rate is but greatly reduced, and this is a contradiction.
Therefore, the high pressure of high-voltage electrostatic field is too high not all right, too low also not all right, and it has individual optimum value.As shown in figure 1, transverse axis High pressure is represented, the longitudinal axis represents clean-up effect, and P represents high-voltage breakdown point, then AP sections are the workspace of clarifier, net the closer to P points Change effect better, we term it, i.e., there is no the ceiling voltage in the case of disruptive discharge in best operating point B, near A then because owing The low clean-up effect of pressure drop.And PC sections, because of overtension, frequent disruptive discharge reduces purification efficiency, and increases the failure of clarifier Rate.
So, the efficiency of high-pressure electrostatic precipitation is made most preferably it is necessary to adjust the output high pressure of high voltage power supply, make at clarifier In best operating point B, it is to avoid in under-voltage condition (near A points) or in over-voltage breakdown discharge condition (PC sections).
However, best operating point B is not fixed, and because the working environment of clarifier is continually changing, best effort Also corresponding dynamic changes point B.Specifically, when air themperature, humidity, oil smoke and dust concentration and dust electric field are enriched with pollutant The change of degree, can cause dielectric strength to change so that the high-voltage breakdown point P of clarifier dust electric field constantly changes, accordingly Best operating point B also changes therewith.As shown in Fig. 2 adjust at best operating point B0 (shown in dotted line) when such as clarifier dispatches from the factory, Best operating point B1 (shown in solid) under the environmental aspect that user uses, both will not be consistent, needs artificial frequently adjustment.Generally User does not have relevant speciality technical ability, so clarifier is usually in two kinds of bad working conditions:The too high collection of high pressure The frequent disruptive discharge of dirt electric field, causes clean-up effect undesirable and increases clarifier fault rate;High pressure is not optimum value, Udst separation effect is reduced in Lower state.Both of which makes the efficiency of high-pressure electrostatic precipitation make a discount.
Change this defective mode, need according to scene temperature, humidity and dust oil smoke concentration, by professional's dynamic Best operating point is caught, the output high pressure of high voltage power supply is constantly adjusted, makes high voltage electrostatic dust precipitator be in optimal work all the time Make a little, to realize best purification effect.This is for high-pressure static cleaner producer and user, although preferable, is but difficult to reality It is existing.
