Description

Blast furnace gas wet-esp electric Field Optimization device
Technical field
The utility model relates to electrostatic precipitation technology field, is specifically related to a kind of blast furnace gas wet-esp electric Field Optimization device.
Background technology
Electric precipitator principle of work is that dusty gas enters by electric precipitator entrance, enters equably electric field after airflow-distribution board current-sharing.After making water fogging, the nozzle that is configured in gas feed and electric field top sprays in the coal gas of the electric field of flowing through, the temperature, pressure, the humidity that make to be cleaned coal gas reach purification requirement, when containing suspension liquid particle, enter after electric field, by charged and trapped by dust collecting electrode under the effect of electrical forces, and flow in ash bucket along dust collecting electrode, then by ash bucket, enter settling tank, and coal gas after purifying is discharged from electric precipitator outlet by electric field.
Adopt traditional blast furnace gas wet-esp to have following problem, 1, no matter be underground water, tap water or pure water, the impurity that contains various compositions and mineral substance in various degree all, therefore, for spray into atomized water clear up the spray header of dedusting pole plate can be because of the long-term precipitation plug nozzle of underground water or tap water impurity, need regularly clear up it, increase later stage cleaning maintenance cost; Because the impurity that spray water is contained can be distinguished to some extent because of the difference of water quality, and if spray water impurity is more, in the process of cleaning dedusting pole plate, in water, impurity is brought into dedusting area, thick laying dust on dedusting pole plate is combined, and not only dust removing effects does not reach set(ting)value and also strengthened dedusting difficulty; 2, the hydraulic pressure size due to spray header can have influence on the cleaning effect to dedusting pole plate, and traditional mode is not all controlled the hydraulic pressure size of spray header, causes water resource waste, affects dust removing effects.
Therefore, the high and dust removing effects of cleaning apparatus maintenance cost expense is bad is urgent problem in current blast furnace gas wet-esp electric Field Optimization.
Utility model content
It is low that the technical problems to be solved in the utility model is to provide a kind of maintenance cost, the blast furnace gas wet-esp electric Field Optimization device of good dedusting effect.
In order to solve the problems of the technologies described above, the utility model provides blast furnace gas wet-esp electric Field Optimization device, comprise the housing that is provided with inlet mouth, air outlet and sewage draining exit, described enclosure interior is provided with dedusting pole plate, described housing top is provided with spray water entrance and its inner upper is provided with the spray header being connected with spray water entrance, and described spray header is provided with shower nozzle, wherein, also comprise self-cleaning filter, described self-cleaning filter is located on described spray header.
Adopt the blast furnace gas wet-esp electric Field Optimization device of technique scheme to have following advantage: 1, owing to being provided with self-cleaning filter on spray header, can improve spray water water quality, spacing is cleaned the effect of incrustation scale, therefore avoided stopping up because of the formation of incrustation scale the situation of shower nozzle, make spray header current smooth and easy, also reduced the trouble of artificial cleaning, saved the maintenance cost in later stage use procedure simultaneously; Meanwhile, due to the raising of water quality, avoid the impurity in spray water and again flowed into the situation that the thick laying dust of dedusting region on dedusting pole plate is combined, dust removing effects is improved, also reduced dedusting difficulty simultaneously; 2, owing to being provided with differential pressure meter on spray header, to the hydraulic pressure of spray water, can carry out suitable adjusting, control as required hydraulic pressure and also further saved water cost, also can reach good dust removing effects simultaneously.
As preferred version, consider the comprehensive of air inlet, exhaust and blowdown, described inlet mouth, air outlet and sewage draining exit are uncovered inside funnel-form.
As preferred version, consider the flexible control to spray water hydraulic pressure, also comprise differential pressure meter, described differential pressure meter is connected with described spray header.
As preferred version, consider that spray water rinses dedusting pole plate comprehensive, at least two, described shower nozzle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment blast furnace gas wet-esp electric Field Optimization device;
Wherein: housing 1; Inlet mouth 11; Air outlet 12; Sewage draining exit 13; Dedusting pole plate 2; Spray water entrance 3; Spray header 4; Shower nozzle 5; Self-cleaning filter 6; Differential pressure meter 7.
embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As shown in Figure 1, a kind of blast furnace gas wet-esp electric Field Optimization device, comprise the housing 1 that is provided with inlet mouth 11, air outlet 12 and sewage draining exit 13, housing 1 inside is provided with dedusting pole plate 2, housing 1 top is provided with spray water entrance 3 and its inner upper is provided with the spray header 4 being connected with spray water entrance 3, and spray header 4 is provided with shower nozzle 5, wherein, also comprise self-cleaning filter 6, self-cleaning filter 6 is located on spray header 4.In addition, consider the comprehensive of air inlet, exhaust and blowdown, inlet mouth 11, air outlet 12 and sewage draining exit 13 are uncovered inside funnel-form, consider the flexible control to spray water hydraulic pressure, also comprise differential pressure meter 7, differential pressure meter 7 is connected with spray header 4, considers that spray water rinses dedusting pole plate 2 comprehensive, and shower nozzle 5 is four.
In the dust removal process of actual blast furnace gas, first the gas of composite grain thing enters housing 1 inside from inlet mouth 11, and by dedusting pole plate 2, the particulate matter in blast furnace gas is removed, last clean gas is got rid of by air outlet 12, and 6 pairs of spray waters of self-cleaning filter of being located on spray header 4 are done filtration treatment in advance, spray water after filtering is sprayed by shower nozzle 5, rinse dedusting pole plate 2, the spray water that has absorbed particulate matter is discharged by sewage draining exit 13, has completed the dedusting work to blast furnace gas.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
