Abstract
The utility model relates to a dustfall nozzle for preventing dust from diffusion. Through a nozzle, a hollow cone fog screen used for blocking the dust and provided with a very large cone angle and a solid cone fog column for mainly removing the dust can be simultaneously generated; the utility model realizes that the dust is prevented from diffusion, and can achieve the purpose of utilizing the spraying fog to catch the dust. For the respirable dust which is especially easy to be carried away by the air, the refluxing swirl formed by the ejector action of the inner fog flow and the outer fog flow is utilized to suck respirable dust to the refluxing swirl to make the catching settling. The nozzle designed by the utility model has the advantages of simple structure, and easy and reliable use; the dust removal efficiency can reach more than 95%.
Description
The utility model relates to a kind of depositing dust nozzle that can prevent dust diffusion effectively, and being widely used in colliery, metallic ore and other has in the production or operation that dust produces.
Atomizing de-dusting is a kind of dust control technology convenient, reliable operation of implementing simply, control to adjust.The critical component of atomizing de-dusting is a nozzle, and what influence dust-laying effect is spray shape and droplet size.Spray shape according to nozzle forms can be divided into nozzle the hollow nozzle two big classes of tapered solid nozzle and taper.What the tapered solid nozzle produced is the solid mist post of a taper; What the hollow nozzle of taper produced then is a taper veil.This two classes nozzle respectively has characteristics in the use: solid nozzle is based on depositing dust, and hollow nozzle is based on resistance dirt.The mist flow velocity of the tapered solid mist post of solid nozzle ejection is bigger, and the dust that is collided by droplet generally can both lower.But also just because of mist flow velocity is big, the air of injection also is easy to the respirable dust that particle diameter is less and blows away around it, has objectively influenced dust-laying effect.The taper veil of hollow nozzle ejection is based on resistance dirt, for the area coverage that makes the taper veil big, very big veil cone angle is generally all arranged, nozzle is also far away relatively from the dirt source, like this at the big end of veil diameter, droplet speed has dropped to very little, except not catching the grit, has lost the effect of resistance dirt in fact.For above-mentioned reasons, present atomizing de-dusting efficient only is 70～80%, in the bigger place of dust-producing amount, only depends on spraying just can not reach requirement, generally also needs other dust-removing method to be used together.
The purpose of this utility model provides and a kind ofly can prevent dust diffusion, the depositing dust nozzle of depositing dust effectively again.
The purpose of this utility model can realize in the following manner: a kind of nozzle that prevents the dust diffusion, include profile and be cylindric, the middle part has the inner core of through hole, have helicla flute on the face of cylinder of inner core, also include tapped overcoat and the interior cover that is fixed on the one end, the two ends of interior cover have greatly, small sircle hole, the middle part is communicated with conical bore, in the hole of interior cover, be provided with the outer core similar to interior cover center hole shape, have spiral slot on the cylinder of the great circle styletable of outer core, the tapered segment of outer core and front end small column and interior inner room form an annular runner, the front end of outer core has aperture, the rear end has big hole, the middle part is communicated with conical bore, and inner core is placed in the big hole of outer core rear end.
The utility model compared with prior art has following advantage: produce the conical hollow veil of resistance dirt and the solid cone shaped mist post of depositing dust simultaneously with a nozzle, can prevent the dust diffusion on the one hand, can realize atomizing de-dusting again on the other hand.The effect of injection in addition, a space arranged between two water smokes, owing to can form two each self-enclosed backflow whirlpools of vortex filament in the space.Because the effect that refluxes can be with the grit in the dust district, the respirable dust that particularly particle diameter that is carried by air easily is very little sucks, and has improved depositing dust efficient greatly.If suitably be equipped with several spraying points in needing the zone of depositing dust, depositing dust efficient can reach more than 95%, and in addition, this nozzle is simple in structure, and is easily manufactured.
Description of drawings:
Accompanying drawing 1 is a nozzle structural representation of the present utility model.
Accompanying drawing 2 is another kind of structural representations of nozzle of the present utility model.
With reference to the accompanying drawings the utility model is described in further detail:
Shown in accompanying drawing 1: a kind of depositing dust nozzle that prevents dust diffusion, include tapped overcoat 1 and be fixed on the interior cover 2 of overcoat 1 one ends by screw thread, the end of overcoat 1 and interior cover 2 joints are provided with sealing ring, prevent leakage.The two ends of interior cover 1 have large and small circular hole, and the middle part is communicated with large and small circular hole with conical bore.In the hole of interior cover 2, be provided with the outer core 3 similar to the center hole shape of interior cover 2, have spiral groove 10 on the cylinder of the great circle styletable of outer core 3, form an annular runner 7 between the conical bore of the tapered segment of outer core 3 and the small column of front end part and interior cover 2 and the small sircle hole, water under high pressure enters runner 7 ejections through groove 10, form the veil of a hollow taper, play the effect of resistance dirt.The roundlet styletable of core 3 has aperture 6 outside, as the spout that forms solid cone shaped mist post.The great circle styletable of outer core 3 has big hole, and the middle part has big column hole and the aperture 6 that bellmouth offers outer core 3 two ends and is connected.Columned inner core 4 is installed in the big hole of core 3 outside, center line along inner core 4 has logical circular hole 9, have helicla flute 8 on its face of cylinder, the middle part forms a conical cavity 5 between inner core 4 and the outer core 3, water under high pressure respectively through helicla flute 8 and logical circular hole 9 to conical cavity 5, aperture 6 ejections through outer core 3 ends form a solid cone shaped mist post.
