Description
The invention belongs to the electrostatic precipitator technology field.
Used electrical tar precipitator mostly is vertical wet method cylinder electrode, though it is better to catch tar grit effect, the smoke treatment amount is subjected to certain limitation, can not be too big.In addition, the sewage of generation can cause secondary pollution, addresses this problem very thorny.
China utility application 88216936.x is a static tar precipitating oil device, also is the board-like horizontal dry method heater assembly electrical tar precipitator of control of dust, and the electrostatic dust-collecting device of JP60-166051A also is provided with average rate plate and pin shaped electric discharging electrodes.It is background technology of the present invention.
The present invention intends releasing the board-like horizontal dry method of a kind of new-type dust collecting electrode and catches the tar device, makes it under the preceding topic that guarantees dust collection effect, and not only the smoke treatment amount is big, and can not produce the secondary pollution that sewage causes.
The present invention is made up of charged section of static cohesion, wide polar distance electrostatic dust collection section and auxiliary control of dust section.Leading portion in the chamber 11 of gathering dust is equipped with the average rate plate 4 of eye with holes, and steel wire 2 is equipped with in the back, in steel wire 2 and the centre of average rate plate 4 and the opposite side of steel wire 2 pin type corona discharge electrode 3 is housed all, forms charged section of static cohesion.At the middle part in the chamber 11 of gathering dust are wide polar distance electrostatic dust collection sections, and this section is made up of wide polar distance control of dust pole plate 7, is fixed on the main pole sheet frame 8.Center corona discharge electrode 1 is housed between its pole plate, is fixed on the negative electrode frame 6, negative electrode frame 6 hangs on the bracing frame 9.By the auxiliary control of dust section that multilayer grooved supplementary set dirt plate 15 is formed, be located at the rear portion in the chamber 11 of gathering dust, be placed between wide polar distance control of dust pole plate 7 and the outlet 16.The auxiliary dust collecting electrode 15 interlaced arrangement of each layer, and be fixed on the interpole sheet frame 14, the heating tube 13 that communicates is installed on the wall in the chamber 11 of gathering dust.In this device, average rate plate 4, steel wire 2, wide polar distance control of dust pole plate 7, auxiliary collecting plate 15 equal ground connection, pin type corona plate 3, center corona discharge electrode 1 connect negative high voltage.
The gas of band tar grit enters from inlet catches the tar device, at first by the eyelet of average rate plate 4, evenly injects the chamber 11 of gathering dust.Because charged section volume that takes up space of static cohesion is very little, when being suspended in tar particulate in the gas, collide with this space anion by charged space, make the tar particle before entering electric field, constantly increase thick and saturated in advance charged.Because the chap of tar grit and the increasing of carrying capacity, the Coulomb force that acts on the grit increases greatly, and purification efficiency significantly improves.This is the operative scenario when being with tar grit gas to condense charged section by static.Then, carry the gas that remains the tar particulate and enter wide polar distance electrostatic dust collection section.Because thicker from charged section mean particle dia of coming of static cohesion, carrying capacity is also bigger, burnt grain jumps on wide polar distance control of dust pole plate 7 in electrostatic field migration velocity is bigger.The normal pole span pole plate of wide polar distance pole plate can strengthen supply voltage, thereby the corresponding increase of electric-field intensity, and wherein near the electric potential gradient the heart corona discharge electrode 1 is more than 2 times of general cottrell, have in addition can reach several times.Simultaneously, near the most advanced and sophisticated corona point of the prickle of center corona discharge electrode 1, can produce conical ion wind, improve the effective migration velocity of grit greatly, help improving dust-collecting efficiency.At last, gas enters auxiliary control of dust section.In this control of dust section, auxiliary collecting plate 15 makes dust-collecting area increase more than 20%.Because the electric field that the grooved fluid field of force that forms in the auxiliary collecting plate 15 and charged grit form has constituted the composite force field of electric field, and dust collection effect is strengthened greatly.For the tar particulate of ingratiating with on each pole plate can be flowed in the oil pooling dipper 18 swimmingly, guarantee each pole plate normal and continuous operation, in heating tube 13, feed high-temperature steam or hot water, the temperature in dedusting chamber 11 is remained at more than 80 ℃.High-temperature steam or hot water feed from heat pipe inlet 12, overflow from heat pipe outlet 17.Cleaned gas is discharged from exporting 16.
Originally catch the tar device and can efficiently catch fine coke tar particles, and the smoke treatment amount is big, does not produce sewage, thereby eliminated secondary pollution.This equipment can not only be given and be contained the dedusting of tar, and adds the purification that promptly can be used for common flour dirt behind the rapping apparatus.
Fig. 1 is this invention structural representation.
Among the figure: the 1st, center corona discharge electrode, the 2nd, steel wire, the 3rd, pin type corona discharge electrode, the 4th, average rate plate, the 5th, inlet, the 6th, negative electrode frame, the 7th, wide polar distance control of dust pole plate, the 8th, main pole sheet frame, the 9th, bracing frame, the 10th, insulator, the 11st, the chamber of gathering dust, the 12nd, heat pipe inlet, be communicated with heating tube 13, the 13rd, heating tube, the 14th, interpole sheet frame, the 15th, auxiliary dust collecting electrode, the 16th, outlet, the 17th, the heat pipe outlet also is communicated with heating tube 13, the 18th, oil pooling dipper.
