There is common problem and defect in the industrial gasses High-voltage electrostatic purification device generally used at present.Ionize tank top one
As have three suspension type porcelain insulator casees and a sleeve pipe porcelain insulator case.In tank body positive pole (receiving electrode) shape have for concentric circles
Formula, have for parallel pipe type, have for honeycomb fashion, be fixed on by Steel Structure on tank skin.Electronegative part is in tank body
Suspension rod, suspension hook, upper and lower part suspension bracket, corona discharge electrode (hundreds of corona wires) and the weight of lower carriage suspension.Band is negative in tank body
Spacing between electric part and positively charged moiety should ensure that enough electrical insulation strengths, in addition, negatively charged part passes through porcelain vase
Insulated with tank body.
When ionizing tank operation, the nitrogen of certain pressure need to be filled with into four insulated cases of tank deck, makes suspension type porcelain vase, sleeve pipe
Porcelain vase is wrapped in nitrogen to be completely cut off with industrial gasses to be clean, while setting electric heater to heat porcelain in this four insulated cases
Bottle, the insulating properties of porcelain vase are maintained with this complicated structure and measure.It is this protection insulation mode it is not only complicated, consumption
Nitrogen and electric energy, and be extremely unreliable.In running, nitrogen constantly can be taken away with industrial gasses, in insulated case
Nitrogen it is fewer and fewer, pressure is more and more lower, it is necessary to which operative employee monitors pressure gauge, ceaselessly supplements nitrogen at any time.As without and
Shi Faxian nitrogen pressures decline, supplement nitrogen in time, then it is gas that the rising of impure industrial gasses, which is filled with insulated case, insulated case,

Coal in air-flow dead band is large-minded, when shut-down (breakdown) mainteance, purging displacement, though there are airway tube and guide valve to lead the coal gas in air-flow dead band
Enter air-flow clear area, but the coal gas replacement that artificial factor and Equipment likely results in air-flow dead band is not to the utmost, opens manhole
Air enters in tank afterwards, easily causes danger.Also, hanging porcelain vase also needs to be heated up to 80-110 DEG C, or even needs inflated with nitrogen to protect
Shield insulation, very complicated, pretty troublesome and extremely unreliable, maintenance and maintenance workload are big.The utility model employs the special of shaping
Insulator is directly installed in ionization tank 20, and fixed negative pole corona wire 11, while employing the high-voltage isulation of shaping again
