Description

High voltage electrostatic dust-remover combined on roof of storehouse

The utility model relates to the box-like high-voltage electrostatic dust separator of a kind of cement silo top group.

Existing cement silo top multipurpose cloth bag dust collector and common simple duster.Use sack cleaner to exist shortcomings such as big, the easy dewfall of storehouse internal pressure, and the effect of common simple duster is undesirable, this is a cement industry an open question of a specified duration.

The purpose of this utility model provides a kind of upright, horizontal combined electric field, simple in structure, convenient for installation and maintenance, top, storehouse combined high-voltage electrostatic precipitator that efficiency of dust collection is high of adopting.

For reaching this purpose, the utility model is combined by upright electric field of double-cylinder type and open type transverse electric field, wherein, and upright electric field of double-cylinder type and common simple and easy high-voltage electrostatic dust separator structural similarity, form by two cylinders, top comes together in an air draft cap, and bottom and open type transverse electric field connect, and hangs with a corona wire in the every upright tube, the upper suspension of corona wire is on eccentric rapping rotating shaft, this axle can hang corona wire by driven by motor, can realize the eccentric rapping of corona wire again.Two the outside is welded with electromagnet in order to realize the vibration dust-cleaning of cylindrical shell.Two upright electric fields of cartridge type have the double action of gathering dust with exhaust, can guide the waste gas of feed bin inside into atmosphere through the air draft cap, and with the trapping dust after charged.The bottom design of the upright electric field of double-cylinder type has an open type circular arch type transverse electric field, this electric field lower open directly covers on the preformed hole at feed bin top, the size of its size and preformed hole coupling, its length can be according to the number combinations of feed bin, and does not influence the performance of electric precipitation.The corona wire of open type transverse electric field is positioned at electric field middle part, and laterally strains by polytetrafluoroethylinsulating insulating tube, dangles when avoiding corona wire longer, a little is provided with polytetrafluoroethylinsulating insulating tube and prevents dangling to hang vertically suspending in midair dangling.Be provided with equal wind switching joint in the junction of upright electric field of cartridge type and open type transverse electric field, thereby make the waste gas that enters in two even.Corona wires upright, horizontal two electric fields directly connect in equal wind switching joint, and a promptly shared power supply can utilize the rapping of the shake realization open type transverse electric field corona wire of the upright electric field corona wire of cartridge type again.Also weld every Si Michu in the shell of the open type transverse electric field outside and to put an electromagnet, to realize the vibration dust-cleaning of transverse electric field housing.Vibrated system of the present utility model is furnished with timing automatic rapping controller, can be to cylindrical shell and housing segmentation vibration dust-cleaning.

Be described in further detail below in conjunction with accompanying drawing.

Operation principle of the present utility model: the waste gas in the cement silo at first enters open type transverse electric field (10), because air velocity diminishes suddenly, realize the diffusion depositing dust, reduce the dust concentration that enters the upright electric field of cartridge type, and most of dust is charged, through equal wind switching joint (8), make waste gas evenly enter the upright electric field (7) of cartridge type, this electric field has and gathers dust and the exhaust double action, guides waste gas into atmosphere through air draft cap (1), and with the trapping dust after charged.Naturally fall into feed bin inside by the two-stage electricity dust part of collecting of gathering dust, the dust of staying on corona wire and cylindrical shell, the housing also can directly fall into feed bin inside by the segmentation vibration dust-cleaning.

Since the utility model make in the feed bin waste gas earlier behind the diffusion depositing dust again through the two-stage high-pressure electrostatic precipitation, and natural exhaust, wind speed is lower, so efficiency of dust collection is high.Because of the dust of collecting can directly fall into feed bin, saved lock wind and ash exhauster again, simple in structure, be easy to install.Owing to be natural exhaust, the storehouse internal pressure reduces, and has avoided the high strength sealing to conveying equipment, and is easy to maintenance.The length of this deduster and highly also can changing according to the quantity of feed bin and the requirement of capacity, make its applicability strong, promote easily, be not only applicable to the top dedusting of cement industry feed bin, and be applicable to the treating flour dust at industry material bank tops such as building materials, metallurgy, coal, grain processing,, be a kind of desirable dedusting equipment also applicable to the treating flour dust of open type material transfer equipment.
