Abstract
The utility model relates to a high pressure swirl nozzle for mist spray dust removal, in particular to the high pressure nozzle for mist spray dust removal of an underground coal mine. A nozzle body comprises a flow guide cavity (2), a rotational flow cavity (4), a cylindrical cavity (5) and a spray cavity (6). Flow guide vanes (3) are arranged in the flow guide cavity, the number of the flow guide vanes is numerous, and the flow guide vanes are spirally arrayed and are bent towards the inside of a cavity body. The rotational flow cavity (4) and the spray cavity (6) are conical cavities, and the short edges of the conical cavities are connected to the cylindrical cavity (5). Four mist spray outlets are designed in the head portion of the nozzle, three outlets are crescent mist spray outlets (7), and each outlet channel is in the tilting direction. Due to the design of the flow guide vanes (3) in the flow guide cavity, water flow rotates, and after liquid fully rotates, the liquid passes through the rotational flow cavity (4). The bypass flow cavity has the function similar to a Venturi tube, so that water pressure is increased, and the fogging degree is promoted. The outlets of the nozzle are designed to be the crescent long and thin outlets (7), sprayed water mist is in an arc type, the fogging degree is promoted, the dust control range is enlarged, and the mist spray dust removal effect is improved.
Description
Technical field
The utility model relates to a kind of High-pressure swirl injection nozzle, especially for the spray for dust suppression nozzle under coal mine.
Background technology
In process of coal mining, can produce a large amount of dust.Dust exerts an adverse impact to all many-sides such as health, production safety, economic benefits.Dust prevention and control is the significant problem that country pays close attention to always, and especially for colliery, dust Occupational Disease Hazards is the Focal point and difficult point of national treating flour dust especially.Before pneumoconiosis authoritative institution report domestic pneumoconiosis cumulative cases and suspicious pneumoconiosis (0+) case nearly 1,000,000, especially attach most importance to coal system, the direct economic loss that annual pneumoconiosis causes to country reaches 8,000,000,000 yuan.In order to prevent and treat dust, each state has all taked a series of measure, for example coal-bed flooding, spray for dust suppression etc.
Spray for dust suppression is a kind of novel dedusting technology, and the nozzle that spray for dust suppression is used is one of core component in atomizing dust-removing system equipment.The quality of spray for dust suppression effect, is decided by a great extent, and can spraying better must be sprayed on produces dirt place, wraps up within the specific limits dust, makes it to be difficult for becoming separated in flight, to reach the object of depositing dust.The shower nozzle using in atomizing dust-removing system at present, is still common sprinkler head mostly, causes like this that condensation rate is low, atomization cone angle is less, water fog particle is larger, can not effectively trap dust, thereby not reach the object of falling chalk dust removing.Because dust removing effects is poor, can consume a large amount of water resources, environment and resource are brought to negative impact.Therefore, in order to improve the efficiency of dust collection of spray for dust suppression, prevent that water is excessive, ensure dust removing effects, be badly in need of invention new type nozzle.
Summary of the invention
For the technical problem of above-mentioned existence, the purpose of this utility model is: overcome the deficiency in prior art, proposed a kind of simple in structurely, cost is lower, low energy consumption and the good high pressure nozzle of atomizing effect.
Technical solution of the present utility model is achieved in that a kind of spray nozzle, described nozzle body, and there is diversion cavity 2, eddy flow chamber 4, cylindrical cavity 5 and the spray chamber 6 of perforation inside; In described diversion cavity, be provided with guide vane 3, guide vane is multi-disc, arrange twist, and to inside cavity bending; Described eddy flow chamber 4, spray chamber 6 are conical cavity, and the minor face of conical cavity is connected on cylindrical cavity 5.Nozzle head, is designed with four spray outlet.Article three, crescent spray outlet 7, exit passageway is incline direction.The water smoke of ejection is used for controlling the dust within the scope of surrounding.Middle rectangular jet outlet 8, the water smoke of ejection is used for the dust in Control Nozzle center range.
Due to the utilization of technique scheme, the utility model compared with prior art has with a little following:
A kind of high pressure cyclone nozzle of the present utility model, by the design of the guide vane in diversion cavity, make current produce rotation, liquid after abundant rotation is propped up, then by shunting chamber.Shunting chamber has the effect of similar Venturi tube, makes the aggravation of water turbulence degree, promotes fogging degree.Jet expansion is designed to the elongated outlet of crescent, makes the water smoke of ejection be arc line type, promotes fogging degree, and improves the effectively scope of control dirt, improves spray for dust suppression effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described
Accompanying drawing 1 is a kind of high pressure cyclone nozzle of the present invention.Liquid passes through successively, the diversion cavity 2, eddy flow chamber 4, cylindrical cavity 5 and the spray chamber 6 that connect successively that in nozzle body 1, are provided with.In the time that liquid enters diversion cavity, the guide vane 3 being provided with in described diversion cavity, rotates liquid.Described eddy flow chamber 4, spray chamber 6 are conical cavity, and the minor face of described conical cavity 5 is connected on respectively on cylindrical cavity.Postrotational liquid, through eddy flow chamber 4, enters circular cone die cavity 5.Due to reducing of diameter, the flow velocity of liquid further increases.The liquid of High Rotation Speed, sprays from spray chamber 6, enters in the outlet of nozzle head.Nozzle head, has four spray outlet, and wherein three crescent outlets 7, and a rectangle outlet 8, from nozzle, eject the liquid of journey atomization.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all according to the present invention, Spirit Essence does equivalence variation or modifies, within all should being encompassed in protection scope of the present invention.
