Description
Technical field
The utility model relates to fume purifier of fume, especially relates to the independent adjustable electrostatic oil fume purification device of a kind of load.
Background technology
Electrostatic oil fume purification device, rely on high direct voltage produce electrostatic field to air by in elaioleucite polarize and charged, the elaioleucite that has polarized is ripped, make it be divided into particle cluster with positive and negative electric charge, under the effect of Coulomb force, be driven on the pole plate, reach the purpose of collection and purification.
The field intensity of electrostatic field depends on the size of DC voltage.During undertension, ELECTROSTATIC FIELD ENERGY is less, although still polarized when elaioleucite passes through the static district, can induce positive and negative charge on the surface, elaioleucite group can not be opened.Can be returned to reset condition after elaioleucite leaves electric field, electrostatic depuration is invalid.During overtension, ELECTROSTATIC FIELD ENERGY is excessive, will puncture medium generation discharge between pole plate, and voltage sharply drops during discharge, and electrostatic depuration also can't carry out.
Which kind of electrode structure no matter conventional high-pressure electrostatic district adopt, and forms by some groups of positive electrodes and negative electrode, and they are together in parallel by the high voltage source box centrally connected power supply.
Because there are technologic difference in spacing, shape between each group positive and negative electrode, and no longer change once just installing, so that their electric-field intensity under unified parallel operation is different.This situation produces following drawback:
One, regulates the High voltage output of high voltage source box, be difficult to take into account the needs of different spacing electrode.When the electric-field intensity that satisfies closely spaced one group of electrode when operating voltage made good purification, one group of electrode that spacing is large did not then reach the electric-field intensity that needs, electrostatic depuration weak effect; On the contrary, when one group of electrode that wish is large with spacing reached optimum electric field intensity, it is excessive that closely spaced one group of electrode is in electric-field intensity, produces electric arc of discharge.In fact, for fear of discharge, many electrode groups are operated under the situation of electric-field intensity deficiency, and the whole purification efficiency of equipment is reduced.Power-supply fluctuation causes that said circumstances existed too when high pressure changed.
Two, conventional high voltage source adopts constant current control, and the electric-field intensity that causes with the automatic correction equipment progressively greasy dirt of accumulation in service descends, and is practical function.But also bring a problem, if it is in different size because of the spacing difference respectively to organize electrode load, the closely spaced electric current of robbing, spacing is large can not get electric current, causes that respectively to organize the electrode operating current very inhomogeneous, the equipment clean inefficiency.
Three, in case because high pressure is higher or media variations produces electric arc of discharge so that certain organizes electrode; voltage sharply drops, and not only each group of in parallel other can't work, and may cause electric energy to concentrate on this group release; in the not good enough situation of power protection, bury hidden fire-fighting danger.
Four, high voltage source box adopts the frequency conversion booster power; the overcurrent of circuit, overload, arcing protection; adopt electric current, voltage feedback signal gauge tap pipe; overload capacity is very low because damage mechanism for semiconductor power device; even the protection design is perfect; reliability is still not high, and in the occasion of supply voltage shakiness, power supply box damages and happens occasionally.
Summary of the invention
The purpose of this utility model is that design provides a kind of load independent adjustable electrostatic oil fume purification device, it can improve the problems referred to above, make and respectively organize interelectrode electric-field intensity convergence balance in the high-pressure electrostatic district, weaken electric arc of discharge, and improve the reliability of high voltage source.
The purpose of this utility model is achieved through the following technical solutions: the independent adjustable electrostatic oil fume purification device of a kind of load, and it is made of housing, air inlet, air outlet, high-pressure electrostatic district and high voltage source box; Described high-pressure electrostatic district is comprised of some groups of positive electrodes and negative electrode, the High voltage output of every group of electrode resistors in series access high voltage source box.Described resistor can be rheostat and the LED light of forward series connection with it.
In conventional electrostatic oil fume deaner, for the load of high voltage source, every group of positive and negative electrode is a nonlinear load, and its electric current is not directly proportional with voltage.Produce electric arc of discharge between the positive and negative electrode when overtension, current break sharply becomes large, voltage drop.Other of its impact parallel connection respectively organized the work of positive and negative electrode, when situation is serious, may cause the semiconductor switch power device damage of high voltage source.
Behind every group of both positive and negative polarity resistors in series, they can adjust to electric current within the specific limits, to improve the purification efficiency of high-pressure electrostatic district integral body, simultaneously, because the metering function of resistor has limited the electric arc of discharge phenomenon.The resistor because nonlinear load has been connected has changed load characteristic, also is a kind of good protection to high voltage source.
Resistor can be connected on negative or positive electrode, decides on concrete technology.Forward is connected in series LED light in resistor loop, can roughly observe the working condition of this group.
Require higher occasion in efficiency, resistor can adopt evatron to replace, and this implements not difficult at electronic technology field, because correct design only needs it to bear the sub-fraction of high pressure.
Beneficial effect
Adopt said structure, obtain certain compensation so that respectively organize the electric-field intensity error that the different spacing of both positive and negative polarity brings, can work in larger mains fluctuations scope, whole purification efficiency is improved; Owing to improved load characteristic, high voltage source is not fragile, has improved the reliability of equipment.
