Abstract
The utility model relates to an outside insulation anti-dewing static dust collector, which belongs to the technical field of environmental protection industries and is mainly used for the dust removal of dispersed and local blowing dust points in industries such as metallurgy, chemical industry, cement, etc. The dust collector mainly solves the problems of the dew condensation, the arc climbing and the electric discharge of static dust collectors. The outdoor post insulator of the dust collector is vertically fixed to a platform on the external side of an upper cylinder body and is provided with a small rain-proof cap and a star-shaped fixed hanging beam. A hook is downwards welded in the center of the hanging beam and is used for hanging an electric corona pole. The height of the upper cylinder body is higher than the height of the outdoor post insulator, dampish gas discharged by the upper cylinder body can not come in contact with the surface of the outdoor post insulator. Consequently, the utility model puts an end to the phenomena of the dew condensation, the arc climbing and the electric discharge of the surfaces of insulating apparatuses.
Description
The utility model relates to a kind of external insulation anti-condensation electrostatic precipitator, is a kind of dispersion of industries such as metallurgy, chemical industry, cement and cleaner of local airborne dust point of being applied to, and belongs to the environment-protecting industrial technical field.
At present, insulation mode in all adopting on the insulation processing of known vertical drum type electrostatic precipitator between discharge electrode and dust collecting electrode, be that seal places electric field inner barrel and the discharge electrode space that coexists, when the dusty gas of humidity passes through the electric field cylindrical shell, also pass through the seal surface, owing to be subjected to temperature difference influence, make the seal surface sweating, under the effect of high-pressure electrostatic, the seal surface of dewfall produces climbs arc discharge, cause supply voltage not reach rated value, equipment can't normally move, and does not have the electrostatic precipitation effect.Known another kind of electrostatic precipitator insulation is to hang seal below rainhat, the seal lower end connects presses gas baffle, hang corona discharge electrode below the pressure gas baffle, Chao Shi dusty gas is when the electric field cylindrical shell rises like this, produce baffling after overvoltage gas baffle outer rim, wherein a part of wet gas current has touched the seal surface, catches a cold and dewfall causes climbing arc discharge, influenced the normal operation of equipment, even equipment is quit work.
The purpose of this utility model provides a kind of dewfall that prevents and climbs arc discharge and improve the external insulation anti-condensation electrostatic precipitator of dust-collecting efficiency.
The purpose of this utility model is achieved in that the height of upper shell is higher than the height that is fixed on its outside outdoor post insulator, make the humid gas that contains that enters in the atmosphere not reach the outdoor post insulator surface, stop the dewfall on outdoor post insulator surface and climbed the arc discharge phenomenon, support insulator upper end is provided with little rainhat and fixing ∏ type hanging beam out of doors, ∏ type hanging beam center suspension hook of welding downwards is used to hang corona discharge electrode, the corona discharge electrode lower end is stretching with the weight hanging, and high-voltage connection is directly received on the ∏ type hanging beam.Leaving directly over the ∏ type hanging beam is the big rainhat of four shore supports, and it is rainproof to be used for the electric field cylindrical shell, and to be that the center is uniform with the electric field cylindrical shell be welded on the platform and the little rainhat in the outdoor post insulator upper end keeps arcing distance for four pillars.Adopt the vibrator in the plesichronous automatic controller control electric field cylindrical shell outside, electric field cylindrical shell and corona discharge electrode are implemented regular rapping, the dust dust stratification that is adsorbed onto on electric field cylinder inner surface and the corona discharge electrode is in time shaken fall, fall in the flue-dust retainer and and in time discharge through feed opening.
Owing to adopt such scheme, can be incorporated into the dusty gas of various dust pollution occasions in the electric field cylindrical shell and be cleaned, collected dust dust stratification can utilize again.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is I-I cutaway view of Fig. 1.
(1), big rainhat (2), pillar (3), ∏ type hanging beam (4), suspension hook (5), upper shell (6), outdoor post insulator (7), platform (8), corona discharge electrode (9), electric field cylindrical shell (10), weight (11), dust inlet (12), leg (13), door to access (14), flue-dust retainer (15), feed opening (16), vibrator (17), little rainhat (18), high-voltage connection cable among the figure
In Fig. 1, to be that the center is uniform with electric field cylindrical shell (9) be welded on the platform (7) four pillars (2), big rainhat (1) is welded on the upper end of four pillars (2), and outdoor post insulator (6) is vertically fixed on the platform (7) in upper shell (5) outside.Outdoor post insulator (6) upper end is provided with little rainhat (17) and fixing ∏ type hanging beam (3), the downward welded suspending hook in ∏ type hanging beam (3) center (4), suspension hook (4) is hung corona discharge electrode (8), corona discharge electrode (8) lower end is stretching on the central axis of electric field cylindrical shell (9) with weight (10) hanging, high-voltage connection cable (18) is connected with ∏ type hanging beam (3) and makes corona discharge electrode (8) connect high-pressure electrostatic, dusty gas is in dust inlet (11) enters dust collection electric field cylindrical shell (9), a large amount of electronics that discharged by corona discharge electrode (8) and negative ions collision and make dust granules charged, charged dust granules is shifted to the inner surface of corona discharge electrode (8) and electric field cylindrical shell under the effect of electric field force, discharge electric charge and be deposited on the inner surface of corona discharge electrode (8) and electric field cylindrical shell (9), again by the vibrator (16) outside the plesichronous automatic controller control electric field cylindrical shell (9), corona discharge electrode (8) and electric field cylindrical shell (9) are implemented regular rapping, the dust dust stratification that is adsorbed on corona discharge electrode (8) and electric field cylindrical shell (9) inner surface is shaken fall in the flue-dust retainer (14), and discharge through feed opening (15).Door to access (13) is to be used for checking dust stratification situation on corona discharge electrode (8) and electric field cylindrical shell (9) inner surface.
In Fig. 2, whole electrostatic precipitator supports through leg (12) and makes electric field cylindrical shell (9) perpendicular to the ground, guarantees that corona discharge electrode (8) hanging on the central axis of electric field cylindrical shell (9), makes field intensity more even.
Characteristics of the present utility model are: the dewfall of having stopped usually to can't resolve in the electrostatic precipitator is climbed the arc discharge problem, dependable performance, simple in structure, cost is low and easy to operate, is electrostatic dust collection equipment ideal in the environmental protection industry.
