Description
Technical field
The utility model belongs to spray and takes hot Heating,Ventilating and Air Conditioning technical field, and in particular to a kind of 360 degree of resistive of block-resistant type drop
Nozzle.
Background technology
Contain a large amount of cryogenic waste heat resources in mine for air exhaustion, is used to recycle the partial heat, at present in mine
Spray heat-exchanger rig is built on retention tower top, to recycle mine for air exhaustion waste heat.Spray heat-exchanger rig internal core component is nozzle,
Conventional nozzle is larger to exhaust resistance at present, and density of setting crosses the more retention tower lower part setting portable blowers of conference and resistance is caused significantly to increase
Add, to influence mine safety operation.The nozzle being arranged at present mainly uses spray chamber all-purpose nozzle, the conventional nozzle atomizing angle
Often below 300 degree of degree so that it is not enough with mine for air exhaustion heat exchange, and air draft is in direct contact with nozzle, tiny spout
It easily blocks and increases maintenance difficulties, reduce heat exchange efficiency.
Utility model content
The purpose of this utility model is that utilizing skill for nozzle in existing mine for air exhaustion waste heat recovery spray heat-exchanger rig
The deficiency of art provides a kind of block-resistant type drop 360 degree of nozzles of resistive.
The utility model adopts the following technical scheme is achieved：
A kind of block-resistant type drop 360 degree of nozzles of resistive, including swirl atomizer, drag reduction cambered surface, and connect swirl atomizer and subtract
Hinder the adjusting guide rod of cambered surface.
The utility model, which further improves, to be, the spout of the cancave cambered surface face swirl atomizer of drag reduction cambered surface setting,
Water spray for reflecting spout changes its water spraying direction so that along 360 degree of ejections of cambered surface.
The utility model further improve is, the drag reduction cambered surface setting convex globoidal back to swirl atomizer spout,
It enables to air to be flowed around cambered surface, avoids the spout of air blow-through swirl atomizer, reduce the resistance that spray group generates air.
The utility model, which further improves, to be, the import direction of swirl atomizer and export direction are arranged vertically.
The utility model has following beneficial technique effect：
After drag reduction cambered surface is connect setting by the utility model with swirl atomizer by adjusting guide rod, swirl atomizer angle passes through
Cambered surface reflects to form 360 degree of water spray angles, and drag reduction cambered surface makes the spout of air and swirl atomizer not be in direct contact, avoids
Swirl atomizer blocks while reducing flow resistance of the swirl atomizer to air.Specifically, the utility model routine from
Drag reduction cambered surface is arranged in heart nozzle front, and the spout on the one hand avoiding air draft and swirl atomizer is in direct contact so that swirl atomizer
It is substantially reduced by the feasibility that impurity in air draft blocks；Still further aspect by drag reduction cambered surface reflect centrifugation nozzle spray flow direction from
And so that water spray angle reaches 360 degree of water outlets, increase heat exchange time of contact raising heat exchange efficiency；Furthermore by the way that drag reduction arc is arranged
Face, air draft is by cambered surface Flow Around, to substantially reduce resistance of the spray group to exhaust system；Cambered surface be arranged with swirl atomizer it
Between the adjustable guide bar that is arranged can adjust cambered surface at a distance from swirl atomizer, the distance can be adjusted in use to change centrifugation spray
Mouth is sprayed water angle, control swirl atomizer water spray and air draft effective time of contact.
In short, the utility model has following advantageous effect：
1, the drag reduction cambered surface being arranged increases swirl atomizer water spray angle, and swirl atomizer spray field may make to reach 360
Degree.
2, the drag reduction cambered surface being arranged makes air flows through to form disturbance in cambered surface when swirl atomizer and water are exchanged heat and flow
Greatly reduce its flow resistance.
3, the drag reduction cambered surface being arranged makes air and swirl atomizer spout non-direct contact effectively prevent existing mine row
Blockage problem of the impurity to swirl atomizer in wind.
4, the drag reduction cambered surface being arranged makes swirl atomizer water spray angle increase, while air disturbance flows through its spray field
Under, effective heat-exchange time of air and water is increased, heat exchange efficiency is improved.
5, the adjustable guide bar being arranged, can adjust distance of the swirl atomizer spout away from drag reduction cambered surface, can be according to specifically not
The clear distance is adjusted with use environment, improves heat exchange property.

Specific implementation mode
The utility model is made further instructions below in conjunction with attached drawing.
Referring to Figures 1 and 2, a kind of block-resistant type drop 360 degree of nozzles of resistive provided by the utility model, including swirl atomizer 1,
Adjustable guide bar 2, drag reduction cambered surface 3 and spout 4.
Swirl atomizer 1 therein is connect with drag reduction cambered surface 3 by adjustable guide bar 2.
In order to be further appreciated that the utility model, now its course of work is described further
After water is sprayed by the spout 4 of swirl atomizer 1, a portion water passes through between drag reduction cambered surface 3 and swirl atomizer 1
Gap spray with air contact heat-exchanging, another part water injection reflected to drag reduction cambered surface 3 by cambered surface after with swirl atomizer 1
Water spray is sprayed and air contact heat-exchanging after hitting by the gap between drag reduction cambered surface 3 and swirl atomizer 1.
360 degree of nozzles of resistive drop in a kind of block-resistant type of the utility model, use novel structure and rational component, increase
Swirl atomizer is sprayed water angle, is reached 360 degree, is reduced the resistance that swirl atomizer generates air, avoids centrifugation and spray
Mouth improves the efficiency of spray heat exchange, to improve mine for air exhaustion due to the dirty impure blocking swirl atomizer problem of air
The overall effect of equal afterheat utilizing systems, improves systematic energy efficiency ratio, has good prospect of the application, can be widely used in mine
Well waste heat recovery etc. sprays among heat transmission equipment.
