Description
Technical field
The utility model is related to field of environment protection equipment, more particularly, to a kind of whirlwind module of flue gas desulfurization and dedusting.
Background technology
With expanding economy, the discharge of current boiler smoke and industrial tail gas increasingly increases, most of flue gas and tail gas
In contain volume of smoke and SO2Deng poisonous gas.Use Wet Flue Gas Desulfurization Technique mostly at present, Wet Flue Gas Desulfurization Technique is based on three-phase
The strong mechanism of mass transfer of Turbulent Mixing, using gas dynamics, makes gas (with solid micronic dust and pernicious gas) and liquid
It is sufficiently mixed, increases the specific surface area of gas-liquid contact, so as to improve desulfurization dust-removing efficiency.Using sky more than current Wet Flue Gas Desulfurization Technique
Tower, the defect of this equipment is that gas-liquid contact time is short, and has some flue gases to have little time reaction directly off absorption tower,
Cause the small flue dust containing high level, gypsum slurries or other desulfurization products in the wet flue gas after desulfurization, flue gas hangover
It is very long, certain pollution is caused to environment.Therefore the country further reduces dirt frequently with " smoke re-heater+bag-type dust " technique
Contaminate the discharge capacity of thing, but the running resistance of this technique is huge, the construction cost of wherein smoke re-heater is very high, plant maintenance into
The maintenance cost of this especially cloth bag is very high, thus constrains the batch production of equipment, it is difficult to reach that environmental protection equipment operation makes
It is required that.This other technique contains large quantity of moisture and tar thing using being limited in scope in the flue dust after biological particles burning
Matter, easily causes cloth bag blocking when using this craft dust removal, and high-temperature flue gas also easily burns cloth bag when using this technique.Though
So also there is cyclone water-film cleaner at present, but it uses traditional whirlwind minor structure, the center of cyclone blade is returned for flue gas
Circulation road, causes spray head to be difficult to arrange, spraying effect is not good, have impact on the dust removing effects of uniform water film.
Utility model content
The applicant is directed to the shortcomings of equipment construction maintenance cost present in above-mentioned existing production is high, running resistance is big,
A kind of whirlwind module rational in infrastructure is provided, carrying out efficient rotary remittance using whirlwind module couples, and gas-liquid-solid three-phase is fully contacted,
Realize that the harmful substance high-speed physical that liquid is carried to gas catches and dissolved, fluid media (medium) is in unsaturated state all the time,
Greatly reduce gas-liquid membrane mass transfer resistance, improve mass-transfer efficiency, so as to realize small space, small liquid-gas ratio, high dedusting, high desulfurization
Target.
The technical scheme that the utility model is used is as follows：
A kind of whirlwind module, is arranged by some cyclonic separation unit horizontals and is formed, the cyclonic separation unit include inner cylinder,
Pilot flow is formed between outer barrel and some guide vanes being arranged between inner cylinder, outer barrel, adjacent two panels guide vane, it is described
The top closure of inner cylinder.
It is used as the further improvement of above-mentioned technical proposal：
The top of the inner cylinder is the enclosed construction of the vertex of a cone, top dome, round platform or frustum.
The cyclonic separation unit radially radiates arrangement, rectangular array arrangement or staggered.
The top of the whirlwind module is provided with spray equipment.
The spray equipment carries out spray to whole whirlwind module region to concentrate spray form, by some spray heads and covered
Lid.
The spray equipment is distribution spray form, and each spray head is correspondingly arranged at each cyclonic separation list one by one
First top.
When the cyclonic separation unit radially radiates arrangement, some spray heads of same radial direction utilize same spray
Shower pipe is connected feed liquor.
