Preferably, apparatus casing air inlet be provided with regulation air quantity adjusting valve.
Preferably, the cathode frame includes the crossbeam and two longerons being arranged in parallel of four parallel arrangements, wherein two
Root crossbeam is located at the outside of apparatus casing, is outer crossbeam, and two crossbeams are located at the inside of apparatus casing in addition, are interior crossbeam, outside
Connected between crossbeam and interior crossbeam by longeron, the two ends of the cathode line are installed between two interior crossbeams by bolt, and
Tensioner spring is provided between bolt and interior crossbeam, one end of supports insulative is fixed with outer crossbeam, the other end and equipment
Housing is fixed.
Compared with prior art, the advantage of the invention is that：
1st, the present invention eliminates pole plate, adopted relative to charged ionization is carried out to dust equipped with pole plate polar curve inside traditional deduster
With brand-new negative electrode arrangement, device height and weight of equipment is greatly reduced, economic performance is superior.
2nd, present invention employs High-efficiency trap, steam collection efficiency is greatly improved.
3rd, the present invention is designed using without flushing, secondary pollution and move that reduction wet dust removal structure is rinsed and brought by water
Power is consumed, and has great social effect to energy-conserving and environment-protective.
4th, the present invention solves the problem of entrainment of fine dust granules administer more difficult in white flue gas after current desulfurization, starts
Smoke gas treatment full technical strategies.

Embodiment
The present invention is described in further detail with reference to embodiments.
Referring to Fig. 1-3, the device of the white smoke emissioning pollution of desulfurization is eliminated the present invention relates to a kind of, including is installed on and sets
The top air-introduced machine 1 at the standby top of housing 4, the upper side of apparatus casing 4 is provided with environmental protection tests mouthful 2, clean for discharging
Gas, guiding device 7 and airflow distribution device 6 are provided with the bottom of apparatus casing 4, and row is offered in the bottom of apparatus casing 4
Dirty valve 10, bottom sides set air inlet 8, High-efficiency trap 3 are provided with the top of apparatus casing 4, in High-efficiency trap 3 and air-flow
Apparatus casing 4 between distribution apparatus 6 is provided with cathode frame 12, cathode frame 12 and is interspersed with cathode line 5, cathode frame 12
Two ends extending equipment housing 4, remainder be located at apparatus casing 4 in, white flue gas is entered by air inlet 8, through adjusting valve 9
Afterwards, flue gas is at the uniform velocity passed through cathode line 5 by guiding device 7 and airflow distribution device 6, then by High-efficiency trap 3, use
High-efficiency trap, quick, efficiently collection is carried out to the water droplet in flue gas, finally air is discharged into outside top air-introduced machine 1.White cigarette
Gas at the uniform velocity by charged after cathode line 5, is supported by the cathode frame 12 of support cathode line 5, cathode frame 12 and equipment
Insulation between housing 4 is isolated by supports insulative 13.Cathode line 5 is to have height with band 72KV high pressures on cathode frame 12
Voltage source 14 is conveyed by wire 15.It is collected into vapor, particulate matter, impurity in white flue gas and passes through blowoff valve 10
Discharge.To ensure equipment normal work, equipment bottom sets by support 11, apparatus casing 4 etc. is supported.
As illustrated in figures 4-5, the cathode frame 12 is arranged in parallel including four crossbeams 12.1 being arranged in parallel and two
Longeron 12.2, wherein two crossbeams 12.1 are located at the outside of apparatus casing 4, it is outer crossbeam, two crossbeams 12.1, which are located at, in addition sets
