Embodiment 1

[0016] The structure of the micro-water mist curtain nozzle of the present embodiment is as follows: figure 1 and figure 2 as shown, figure 1 It is a schematic cross-sectional view of the structure of the micro-water mist curtain nozzle of the present embodiment, figure 2 is its front view. This micro-water mist curtain nozzle comprises a nozzle housing 1 with a water inlet 16 and a water outlet 15 and five atomizing nozzles 14. The inside of the nozzle housing 1 is a cylindrical inner cavity 2, and the top of the cylindrical inner cavity 2 is It is a tapered groove 3, and the nozzle housing 1 is made of high-strength alloy material; five diversion holes 4 are arranged in a semi-circular shape on the nozzle housing 1 at the water outlet 15, image 3 It is a schematic view of the diversion hole of the micro-water mist curtain nozzle of the present invention, the diversion hole 4 is connected to the nozzle body 5 through an internal thread; the water flow flows into the noz...

Embodiment 2

[0020] Figure 7 It is a schematic cross-sectional view of the structure of the double-row nozzle micro-water mist curtain nozzle of the present embodiment, and its front view, schematic diagram of the diversion hole, schematic cross-sectional view of the nozzle and schematic diagram of the atomizing core are the same as those of Embodiment 1. This micro-water mist curtain nozzle comprises a nozzle housing 1 with a water inlet 16 and a water outlet 15 and nine atomizing nozzles 14. The inside of the nozzle housing 1 is a cylindrical inner cavity 2, and the top of the cylindrical inner cavity 2 is It is a tapered groove 3, and the nozzle housing 1 is made of high-strength alloy material; two rows of nine diversion holes 4 arranged staggered and evenly arranged in a semi-circular shape are set on the nozzle housing 1 at the water outlet 15, and the guide The orifice 4 is connected to the nozzle body 5 through an internal thread; the water flows into the cylindrical inner cavity ...

Abstract

The invention discloses a micro fog screen sprayer. The micro fog screen sprayer is characterized in that a nozzle of the micro fog screen sprayer uses the design of atomization core with the combination of six diversion chutes and spherical groove; the micro fog screen sprayer uses a closed inner half ring cavity of which one side of the shell is protruded outwards; an outer half ring cavity provided with 1-3 rows of equal-sized diversion holes penetrating through the shell is arranged at the other side of the shell; the axis of the diversion hole of the sprayer is perpendicular to the axis of the cylindrical inner cavity; the design of the atomization core with diversion chutes and spherical groove combination is adopted, so that the single sprayer directly forms a plane micro fog screen. By adopting the micro fog screen sprayer, the shortages that the grain size of the liquid drop is greater than 1mm, the distribution is uneven, the atomization performance is poor and the water consumption is high, a fog screen can be generated only when multiple water fog sprayers are combined and the thickness is uneven in the prior fog screen art are overcome, so that effective smoke blockage, heat absorption and heat radiation attenuation are realized.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a special nozzle capable of producing a micro-water mist curtain capable of blocking smoke and attenuating heat radiation. Background technique [0002] In GB50084-2005 "Code for Design of Automatic Sprinkler System", the water curtain system is mentioned as an effective fire prevention measure. However, most of the existing water curtain systems use rain or sprinkler nozzles, which not only consume a lot of water, cause serious water pollution, but also have large droplet sizes, uneven thickness of water curtains, and poor fire prevention effects. A kind of " water curtain nozzle " announced as Chinese Patent No. CN2499126Y, its nozzle front end has axially telescopic collar, and depth is greater than the gap of nozzle outlet radius, and gap both sides opens movable wing. Although this water curtain nozzle can adjust and change the thickness and width of the...
