Advantage of the present utility model and beneficial effect:
1, the utility model gas inlet adopts direct-insert tangential admission, entrance barrel body end cover is designed to spirality simultaneously, the spiral stream guidance of tail gas can not only be realized, slow down the tail gas of adjacent two spiral coils and mutually disturb, and tail gas in air inlet pipe can be avoided to greatest extent to discharge from exhaust outlet with the central gas stream risen and reduce efficiency of dust collection.
The spiral cover plate of 2, the utility model porch is provided with high pressure main burner nozzle, and after baking tail gases contacts with atomized water, most of dust will be atomized water-setting collecting and catch, and make granule dust accumulation become bulky grain, be beneficial to cyclonic separation.Water smoke is by the ammonia nitrogen absorption in baking tail gases in water simultaneously, reaches preliminary except the pernicious gas such as ammonia, acid object.
3, the uniform multiple auxiliary jet spray mouth of a river of the utility model gas inlet section cylindrical shell circumferencial direction, ensure that deduster inwall forms uniform liquid film, the aggegation dust and the water smoke that make to rotate into deduster adhere on moisture film under the influence of centrifugal force, and the dust eliminating dry whirlwind type dust cleaner is reduced the problem of efficiency of dust collection at wall place by reentrainment.
In sum, the utility model can realize efficient dedusting simultaneously, except ammonia, deacidify object, and equipment investment cost is much smaller than the spray packed tower being generally used for vent gas treatment; For valuable particle, cyclonic water film deduster can also realize recycling with minimum cost.

Detailed description of the invention
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.First-selected embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, the object of these embodiments is provided to be make to disclosure of the present utility model more thoroughly comprehensively.
It should be noted that, when element is considered to " setting " on another element, it can be set directly on another element or may there is centering elements simultaneously.
Unless otherwise defined, all technology used herein are identical with the implication that those skilled in the art of the present utility model understand usually with scientific terminology.The term used in description, just in order to describe concrete enforcement object, is not intended to be restriction the utility model.
As shown in Figure 1, 2, deduster entirety is band inverted pyramidal structures, and its critical piece comprises and directly enters tangential admission pipe 1, auxiliary jet 2, upright cylinder 3, right circuit cone cylindrical shell 4, conical end socket 5, central row tracheae 6, spiral cover plate 7, main burner 8, radiation shield 9, slurry discharge ports 10.Wherein directly enter tangential admission pipe 1 for rectangular configuration, air inlet pipe can be made all tangent with upright cylinder 3 in whole short transverse on the one hand, increase the contact surface of inlet tube and cylindrical shell, allow tail gas form membranaceous eddy flow fluidised form; Effectively can increase gas inlet place flow area on the other hand, in PROCESS FOR TREATMENT amount one timing, reduce the deduster pressure loss, thus the power consumption of corresponding blower fan can be reduced.The spiral cover plate 7 of upright cylinder 3 is designed to spirality, the spiral stream guidance that spiral cover plate 7 can not only realize tail gas, the tail gas slowing down adjacent two spiral coils disturb mutually, and tail gas can also to be avoided in air inlet pipe to greatest extent to discharge with the central gas stream risen from center blast pipe 6 and reduce efficiency of dust collection.
As shown in Figures 1 to 3, main burner 8 is arranged on spiral cover plate 7, forms primarily of blind flange 81, flange 82, sleeve pipe 83, shower 84, double end pipe collar 85, spiral nozzle 86.Main burner 8 is for making water fogging and evenly spraying in deduster, and after baking tail gases contacts with atomized water, most of dust will be atomized water-setting collecting and catch, and makes granule dust accumulation become bulky grain, is beneficial to cyclonic separation below.Ammonia in baking tail gases, acid are adsorbed in water by water smoke simultaneously, reach the preliminary object except the pernicious gas such as ammonia, acid.For dedusting as far as possible, except ammonia, deacidification, main burner 8 can be arranged multiple along spiral cover plate 7.
As shown in Figure 2, auxiliary jet 2 is evenly arranged along upright cylinder 3 circumferencial direction, for ensureing that deduster inwall forms uniform liquid film, the aggegation dust and the water smoke that make to rotate into deduster adhere on moisture film under centrifugal action, the quantity of auxiliary jet 2 should not be less than three, and the present embodiment is provided with four.Meanwhile, the dust that the existence of moisture film also eliminates dry whirlwind type dust cleaner is reduced the problem of efficiency of dust collection at wall place by reentrainment.
As shown in Figure 1, right circuit cone cylindrical shell 4 is arranged to large end down, and when making air-flow downward eddy flow, radius of turn increases gradually, reduces dusty gas is discharged to central row tracheae 6 possibility by the short circuit of Swirl district further.The Main Function of the radiation shield 9 established in right circuit cone cylindrical shell 4 is that the air-flow making rotation downward is drawn close to deduster center, and formation turns to constant, and flow direction interior rotational gas flow from bottom to top, finally makes purified gas discharge from center blast pipe 6.Have certain gap between radiation shield 9 and right circuit cone cylindrical shell 4, absorb the slurries of dust and pernicious gas, a small amount of tail gas then thus passage enter in conical end socket 5.Then slurries are delivered to recovery system through slurry discharge ports 10 and reclaim, and avoid expensive catalyst to run off, or deliver to drainage and process, and the air-vent that a small amount of tail gas is then opened through radiation shield 9 top is incorporated to purified gas and discharges together.For making rotational gas flow and downward outer rotational gas flow upwards keep relative stability, when radiation shield 9 is installed its axle center should with deduster axis coinciding, and the air-vent at its top should keep level.
Embodiment described in the utility model is only the description carried out preferred embodiment of the present utility model; not the utility model design and scope are limited; under the prerequisite not departing from the utility model design philosophy; the various modification that in this area, engineers and technicians make the technical solution of the utility model and improvement; protection domain of the present utility model all should be fallen into; the technology contents of the utility model request protection, all records in detail in the claims.
