The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
Mine nitrogen water mist generating device of the present invention mainly is made up of water guide cyclone 1, atomizer 2, atomizing cylindrical shell 3, rectification cylindrical shell 4.Be provided with atomizer 2 in the atomizing cylindrical shell 3 and insert the water guide cyclone 1 in the atomizer 2 with head; Water guide cyclone 1 is connected with the afterbody of atomizing cylindrical shell 3; The afterbody of water guide cyclone 1 has and leads to anterior taper pathway 10, and the front portion of water guide cyclone 1 is turriform, and front end is provided with the convergent wind-guiding helicla flute 7 that the helical blade radius dwindles formation gradually; Head is provided with a plurality of hole for water sprayings 6, and the horizontal sextant angle of the axially bored line of a plurality of hole for water sprayings 6 and water guide cyclone 1 axis is about 30 °; Atomizing cylindrical shell 3 walls of atomizer 2 entrance are provided with the air inlet port 14 that feeds nitrogen; The front portion of atomizer 2 is bowl-type; Bowl has a plurality of air vents 12 at the end; The bowl outer wall matches with atomizing cylindrical shell 3 inwalls, and the front end of atomizing cylindrical shell 3 is provided with baffle ring 19, and the rear portion is provided with the atomizing cylindrical shell that links to each other with water guide cyclone 1 and regulates screw thread 8.The rear portion of atomizer 2 is cup-shaped, and the cup end communicated with the bowl end, and the outer wall of cup is provided with fixed block 11; The afterbody of water guide cyclone 1 is provided with the coupled rectifying tube that connects 4, is provided with the mounting groove 16 of screen pack 5 and mounting filtering net 5 in the rectifying tube 4, and atomizing cylindrical shell 3 is provided with the Connection Block 18 that is fixed with rectifying tube 4 opposing end surfaces; The front portion of rectification cylindrical shell 4 is provided with the rectification cylindrical shell that links to each other with water guide cyclone 1 and regulates screw thread 17.Water guide cyclone 1 is provided with adjusting handle 9.
The course of work: supply channel under rectification cylindrical shell 4 and the mine is linked to each other, and nitrogen pipeline links to each other under the air inlet 14 of atomising device cylindrical shell 3 and the mine, when water when supply channel gets into rectification cylindrical shell 4; At first pass through screen pack 5, impurity filters in 5 pairs of water of screen pack, gets into the conduit pipe 10 in the water guide cyclone 1 then; Because the cross-sectional area of conduit pipe 10 reduces gradually, and the static pressure of current is transformed into ram compression, speed increases gradually in this process; Spray into air guide channel 13 from hole for water spraying 6 at last, nitrogen got into from air inlet 14 cylindrical shell 3 took place this moment, behind the convergent wind-guiding helicla flute 7 of a part of nitrogen via water guide cyclone 1 outside; Because air guide channel 13 shrinks gradually; When nitrogen speed increases, be rotated, form rotating jet, will dispel the formation droplet from the current of hole for water spraying 6 ejections along the wind-guiding helicla flute.Nitrogen and droplet mix rotating jet through the throat of air guide channel 13 when (the cup end and a bowl joint portion, the end), speed increases suddenly, and surpasses the velocity of sound; When getting into the bowl-type spray chamber; Speed reduces suddenly again and forms shock wave, and the high speed rotating jet receives violent disturbance, and atomizing effect is strengthened.The other a part of nitrogen that gets into from air inlet 14 simultaneously sprays with air vent 12 through air guide path 15 has strengthened disturbance again, makes the particle diameter of water smoke further reduce, thereby forms stable nitrogen water mist.
