Description
Technical field
It the utility model is related to technical field of electrostatic dust collection, in particular to a kind of novel electrostatic with Laval nozzle remove
Dirt device.
Background technology
Pass by more than 100 years since First electric cleaner in 1906 is born, its major part electric field structure is not
Once big change occurred, is still corona wire electric discharge, dust collecting electrode collection dust, and inverse corona and dust fly upward problem all the time not again
The solution obtained.
What the electrostatic precipitator being commonly used, its operation principle and structure were write referring to Li Shi《Electrostatic precipitator》
Page 25~113 (metallurgical industry publishing house, the first edition in 1997).This electrostatic precipitator is gathered dust using cathodic discharge, anode
The principle of the two poles of the earth work, there is following deficiency：
1st, not easily collecting high resistivity dust.Because high resistivity dust resistance value is high, charged grit reaches collecting polar plate
Shi Buyi is neutralized in time, remaining anion is occurred and is gathered, and weakens anode surface electric-field intensity, and grit migration velocity declines.
Constantly accumulation makes adhesive force increase of the grit to anode, is not easy to shake and forms high resistivity dust layer.When dust constantly gathers,
Field strength of gathering dust is equal with inverse corona field strength, or more than gather dust field strength when, cause partial breakdown, dust collector efficiency declines to a great extent.Therefore
For high resistivity dust, it is necessary to using quenched and spraying treatment, and operational efficiency is still undesirable.
2nd, it is not easy to purify low resistivity dust.Due to bear electricity low resistivity grit reach collecting polar plate when immediately in
With also have little time viscous integrated agglomerate just departing from pole plate, float to flue again, it is necessary to charged again.Said process repeats
It is existing, it have impact on efficiency of dust collection.
Although the dust collecting electrode of common deduster employs the fluted form of various bands, to prevent reentrainment of dust, choked flow
Effect is still not satisfactory, certain flow velocity is still suffered near dust collecting electrode, and bear electricity grit drives into the electric wind formed and existed
It will turn back after reaching dust collecting electrode and form many vortex, these vortex will confuse the sedimentation order for the grit for reaching dust collecting electrode, make
Some grits float air-returen flue again, are taken away by flue gas stream, so as to reduce efficiency of dust collection.
3rd, equipment steel consumption is high.Common electrostatic duster generally use barb type cathodic discharge pole, anode use precipitation pole plate,
Thus sheet metal consumption is big, high equipment cost.
4th, it is big to run waste of energy.Electric cleaner nearly all operates in spark and adjusted under working method, electric cleaner operation
During efficiency it is very low, substantial amounts of electric energy is not intended to gather dust, but is wasted.
Application No. ZL95222714.2 Chinese patent discloses a kind of light synthetic electric dust remover, and the patent is in Yi Yin
Some anodes are extremely set in the certain radius at center or certain distance, and lightweight insulated damping is set in anode outer ring
Band, collectively constitute dust collecting electrode.But the lightweight collecting plate of lightweight insulated damping band composition is easily disturbed by electric field flow, and
And heat resistanceheat resistant change ability is weak, can be only applied in low temperature environment；Lightweight collecting plate adds the additional electric field that insulation polar curve is formed, flat at it
Caused by plank frame in static accumulation area, dust still dissipation of energy；Insulation polar curve in original additional electric field, easily by
The damage of the strong flue dust of corrosivity, influences service life.
For this problem, the B of Chinese patent CN 102896044 disclose a kind of electrostatic precipitator, including housing, described
Negative electrode and anode made of electric wire are provided with housing, the anode is nearby provided with parallel and length is of substantially equal with anode
Collecting plate；It is characterized in that:The collecting plate lives anode from anode side semi-surrounding, the collecting plate and anode apart from model
It is 5-150mm to enclose, and the upper/lower terminal of the collecting plate is fixed on the upper/lower terminal of housing by insulator respectively；The insulation
Sub- entirety is in umbrella, and the insulator stage casing is provided with the projection of dentation；The negative electrode is spaced along its length is formed with latch closure.
Such structure can cause the dust collection efficiency of electric cleaner effectively to improve, but simultaneous problem is attached
The dust in electrostatic precipitator and particulate matter can also increase, so as to the situation for causing dust collection efficiency gradually to reduce.
Utility model content
For the problems of the prior art, the utility model, which provides, a kind of can effectively remove carrying for dust and particulate matter
The Novel electrostatic precipitator of Laval nozzle.
In order to achieve the above object, the technical solution of the utility model is：A kind of novel electrostatic with Laval nozzle
Deduster, including housing, the housing is interior to be provided with negative electrode and anode made of electric wire, and the anode is nearby provided with and sun
Extremely parallel and of substantially equal length collecting plate, state collecting plate and live anode from anode side semi-surrounding, the collecting plate it is upper and lower
Both ends are fixed on the upper/lower terminal of housing by insulator respectively；The insulator is in integrally umbrella, and the insulator stage casing is set
There is the projection of dentation；The negative electrode is spaced along its length is formed with latch closure；Also include at least one Laval nozzle, the Bearing score
Your nozzle is arranged on the top of housing.
As an improvement, the Laval nozzle is rotatably assorted with case top.
As an improvement, the quantity of the Laval nozzle is three.
As an improvement, the quantity of the Laval nozzle is five.
