Technical field
The utility model relates to a kind of electric-melting magnesium stove electric cleaner.
Background technology
Electric-melting magnesium stove produces a large amount of flue dust in the course of the work, for reaching the requirement of environmental protection, needs special equipment to process flue dust.At present, conventionally adopt electric cleaner, its internal structure is the electric field that corona wire and dust collecting electrode form, and in common high voltage, electric field, pole span is in 300mm left and right, and due to electric-melting magnesium stove, the effect of this kind of electric cleaner is not fine.Meanwhile, the supporting insulator of dust remover roof is vulnerable to pollute in use for some time, failure of insulation and cannot send high-tension electricity.Conventionally adopt taper insulating sleeve.When electric cleaner operation, the surface of insulator all contacts with flue dust, if the condensation such as steam, acid in flue dust is adhered on insulator, its surface insulation lost efficacy, and formed surface leakage, and when serious, electric field send and do not power on, the heat of electric leakage burns out insulator and breaks or rupture, in flue dust, some particle is attached to insulator surface and also can causes insulation breakdown, and traditional processing method is labor cleaning or blowing cleaning, fails to tackle the problem at its root.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electric-melting magnesium stove electric cleaner, good dedusting effect, and insulator surface is pollution-free, makes electric cleaner stable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of electric-melting magnesium stove electric cleaner, use EHT supply, air outlet on electric cleaner top, bottom connects exhaust fume collecting hood by blast pipe, electric cleaner top is provided with insulator chamber, in insulator chamber, be provided with insulator, suspention corona wire in insulator, corona wire is longitudinally arranged in electric cleaner cylindrical shell, by point of contact horizontally set multilayer corona ring between the corona wire longitudinally arranging, cylinder inboard wall is provided with movable liner plate as dust collecting electrode, 1-3 layer corona ring sidewall near insulator is provided with wing plate, what wing plate evenly interlocked is fixed on corona ring both sides, described insulator chamber comprises insulator, airduct, jet pipe, airduct is arranged on insulator top, airduct communicates with jet pipe, jet pipe is arranged on insulator outside, jet pipe is provided with spray orifice, spray orifice is corresponding with insulator outer wall.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1-Fig. 3, a kind of electric-melting magnesium stove electric cleaner, use EHT supply, air outlet 10 on electric cleaner top, bottom connects exhaust fume collecting hood by blast pipe, electric cleaner top is provided with insulator chamber 2, in insulator chamber 2, be provided with insulator 1, the interior suspention corona wire 4 of insulator 1, corona wire 4 is longitudinally arranged in electric cleaner cylindrical shell, by point of contact 5 horizontally set multilayer corona ring 3 between the corona wire 4 longitudinally arranging, cylinder inboard wall is provided with movable liner plate 6 as dust collecting electrode, be fixed with wing plate 7 near on 1-3 layer corona ring 3 sidewalls of insulator 1, what wing plate 7 evenly interlocked is fixed on corona ring 3 both sides, described insulator chamber 2 comprises insulator 1, airduct 11, jet pipe 8, airduct 11 is arranged on insulator 1 top, airduct 11 communicates with jet pipe 8, jet pipe 8 is arranged on insulator 1 outside, jet pipe 8 is provided with spray orifice, spray orifice is corresponding with insulator 1 outer wall.Jet pipe 8 is fixed by the metal supporting rings 9 that is fixed on insulator chamber 2 sidewalls.
Airduct 11 is on insulator 1 top, and jet pipe 8 stretches in metal supporting rings 9, and by insulator chamber 2 ground connection, the hot blast spraying when air feed forms air curtain in insulator 1 lower surface, blocks flue dust by entering insulator chamber 2 in electric cleaner cylindrical shell.Jet pipe 8 diameters and jet amount decide according to the pressure of device interior flue dust.The spray orifice of jet pipe 8 can directly purge insulator surface flue dust, simultaneously, the hot blast that jet pipe 8 sprays forms air curtain at insulator 1 bottom margin, the angle of jet pipe 8 determines to form the position of air curtain, general 8 mouthfuls of diameters of jet pipe select 1～5mm, the pressure that jet amount is pressed process gas regulates, wind regime pressure 3000～3500Pa.
Adopt direct current more than 12kV to be transported to electric field, form powerful electrostatic field after energising, dust collection effect is good.Owing to adopting superpower electric field, in electric field, pole span is widened to 400mm, is applicable to electric capacity magnesium kiln smoke and dust treatment.Because flue dust is upwards discharged by bottom, thereby the corona ring 3 near insulator 1 arranges wing plate 7 on deduster top, to increase the absorption affinity of fine dust, strengthens the efficiency of dust collection of fine solid particle, makes dust removing effects better.The interior airduct 11 that arranges of insulator chamber 2, and purging insulator 1 surface by jet pipe 8, insulator 1 surface just can not be polluted, and can fundamentally eliminate insulator 1 because of the contaminated situation appearance destroying, do not affect the normal operation of system, can not destroy the balance of production system gas pressure.
