Abstract
The invention provides a superfine dry powder sprayer. The dry powder sprayer comprises a sprayer body and a spray plate, both of which are in threaded connection with each other; the spray plate is formed by connecting the bottom of a cylinder with a frustum; 8-12 horizontal holes are formed in the bottom of the cylinder, 4-8 inclined spray holes are formed in the inclined surfaces of the four sides of the frustum, and a vertically downward spray hole is formed in the center of the frustum. The superfine dry powder sprayer has the characteristics of simple structure and thorough expansion and atomization of superfine dry powder; the superfine dry powder sprayer can be applied to either a fixed automatic fire extinguishing system to realize total flooding type extinguishment of fire, or a mobile fire extinguishing system to put out local fire and realize remote fire extinguishment.
Description
Technical field
The present invention relates to a kind of ultra-fine dry powder shower nozzle.
Background technology
Ultra-fine dry powder extinguishing agent is a kind of low toxicity, the efficient fire-extinguishing agent that developed recently gets up, and its fire extinguishing effectiveness is 6～8 times of common powder extinguishing agent, and market prospects are wide.Superfine dry powder fire-distinguishing system is widely used in oil, natural gas extraction, transportation and field of storage, is applicable to put out oil, natural gas fire.Can superfine dry powder fire-distinguishing system give full play to fire extinguishing function, and can key be the ultra-fine dry powder the ejecting atomization of fully expanding, and forms aerosol, and form aerocolloidal key in the structural design of shower nozzle.At present, known ultra-fine dry powder shower nozzle mostly is single spraying pore structure, though have superiority in jet length, is unfavorable for the quick disperse of ultra-fine dry powder, can not realize rapid covering flame, reaches the object of fire extinguishing.
Summary of the invention
Its object of the present invention is just to provide a kind of ultra-fine dry powder shower nozzle, there is simple in structure, the sufficient feature of ultra-fine dry powder expansion atomization, both can be used for fixed automatic fire extinguishing system, realizing total flooding stamps out a fire, also can be for portable fire extinguishing system, put out Local Fire, realize fire extinguishing at a distance.
The technical scheme that realizes above-mentioned purpose and take, comprise head body and injection dish, head body is threaded with injection dish, described injection dish connects frustum by Cylinder bottom and forms, Cylinder bottom is provided with 8 ~ 12 lateral apertures, frustum inclined-plane surrounding is provided with 4～8 oblique spray-holes, and frustum center is provided with spray-hole vertically downward.
Compared with prior art the present invention has the following advantages.
Because head body is provided with tapered runner, be convenient to form dry powder aerosol, spray tray bottom tapered protrusion is set, being convenient to dry powder evenly spreads to surrounding, spray tray bottom and surrounding and open spray-hole, spray-hole is angled, and the aerosol of being convenient to ejection spreads evenly rapidly in space.There is simple in structure, the sufficient feature of ultra-fine dry powder expansion atomization, both can be used for fixed automatic fire extinguishing system, realize total flooding and stamp out a fire, also can put out Local Fire for portable fire extinguishing system, realize fire extinguishing at a distance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is this apparatus structure schematic diagram;
Fig. 2 is head body structural representation in this device;
Fig. 3 is injection dish structural representation in this device.
The specific embodiment
Comprise head body 1 and injection dish 2, head body 1 is threaded with injection dish 2, as shown in Figure 1, described injection dish 2 connects frustum 8 by Cylinder 9 bottoms and forms, Cylinder 9 bottoms are provided with 8 ~ 12 lateral apertures 5, frustum 8 inclined-plane surroundings are provided with 4～8 oblique spray-holes 6, and frustum 8 centers are provided with spray-hole 7 vertically downward, as shown in Figure 3.
Described head body 1 center is provided with biconial through hole 3, head body 1 upper end is provided with straight thread or tapered thread is connected with pipeline, lower end is provided with straight thread and is connected with injection dish 2, and described biconial through hole 3 flow passage entry apertures, upper end are greater than aperture, runner exit place, lower end, as shown in Figure 2.
The angle N of described oblique spray-hole 6 is 60 °～135 °, and described spray-hole 7 ends arrange 60 ° of tapered openings, as shown in Figure 3.
Described Cylinder 9 outer surfaces are provided with 2mm reticulate pattern 4, as shown in Figure 3.
Embodiment
This apparatus structure as shown in Figure 1, comprises head body 1 and injection dish 2, and both are connected by screw thread.
Head body 1, as shown in Figure 2, extinguishing chemical runner is contained in inside, and it is shaped as taper, the entrance point of its extinguishing chemical is large, and along with the extension of runner, aperture progressively dwindles, after narrowing down to certain threshold values, aperture progressively expands along with the extension of runner again, and flow passage entry aperture must be greater than exit.Head body 1 upper end is provided with straight thread or tapered thread is connected with pipeline, and lower end is provided with straight thread and is connected with injection dish 2.
Injection is coiled 2 structures as shown in Figure 3, in injection, coil 2 tops 8 ~ 12 lateral apertures 5 are set, in injection, coil 2 bottom surroundings and offer oblique spray-hole 6, according to practical situations, its quantity changes within the scope of 4～8, and tiltedly the angle of spray-hole 6 changes within the scope of 60 °～135 °.Injection is coiled 2 bottoms and is provided with tapered protrusion, and offers spray-hole 7 vertically downward in tapered protrusion, and spray-hole 7 ends arrange tapered opening.
During work, ultra-fine dry powder extinguishing agent is under 1.4 ~ 1.6 MPa pressure-driven, from pipeline, enter nozzle, and flow forward with nozzle flow channel, along with flow passage aperture is dwindled, the flow velocity of extinguishing chemical increases, when extinguishing chemical is by after the threshold values of aperture, due to aperture sudden enlargement, extinguishing chemical fully mixes with air, volume expands rapidly, form ultra-fine dry powder aerosol, from head body, the dry powder aerosol of hole ejection clashes into the tapered protrusion of spraying tray bottom, part dry powder aerosol outwards sprays by the through hole arranging in pyramidal projections, a part of dry powder aerosol is under tapered protrusion effect in addition, to spraying tray bottom surrounding, evenly spread, and the spray-hole arranging from bottom surrounding ejection, the dry powder aerosol of ejection further mixes with air, volume further expands, finally in space, form equally distributed aerosol.
This device is a kind of ultra-fine dry powder shower nozzle being applied in fixed or portable fire extinguishing system, this shower nozzle coils 2 two parts by head body 1 and injection and forms, in head body 1, be provided with the tapered runner that first shrinks and expand, in injection, coil 2 tops 8 ~ 12 lateral apertures are set, in injection, coil 2 bottom surroundings and offer oblique spray-hole, according to practical situations, its quantity changes within the scope of 4～8, the angle of spray-hole changes within the scope of 60 °～135 °, injection is coiled 2 bottoms and is provided with tapered protrusion, and offer spray-hole vertically downward in tapered protrusion, spray-hole end arranges tapered opening.
This device also can be used for portable local fire extinguishing, ultra-fine dry powder shower nozzle connects extinguishing chemical storage tank by flexible pipe, when there is the local condition of a fire, injection dish 2 is removed from head body 1, and the perforate of head body 1 bottom is aimed to flame, after system starts, from the ultra-fine dry powder aerosol jet of head body 1 ejection, realize remote portable fire extinguishing.
