Summary of the invention
The object of the present invention is to provide a kind of atomizer, when can producing suitable atomizing effect, reduce the loss of damming of fluid, increase the protection area of spray momentum and single shower nozzle, and simplify nozzle structure and reduce cost.
The technical solution adopted for the present invention to solve the technical problems is: the end at nozzle housing has fluid intake and connector, have the multistage atomizing nozzle of ground floor on the other end of nozzle housing, direction from ground floor multistage atomizing nozzle to fluid intake on nozzle housing has the multistage atomizing nozzle of multilayer successively, multistage atomizing nozzle on each layer evenly distributes or uneven distribution, and the multistage atomizing nozzle has the through hole that enlarges step by step to the nozzle housing outside direction from nozzle housing inside.
Compare with existing atomizer, the beneficial effect that the present invention has is: adopt multilayer multistage atomizing nozzle, replace in the past revolve that core, barrier block, the assisted atomization mode of these three kinds of machineries of helical spring, simplify nozzle structure; Adopt multilayer multistage atomizing nozzle, (the ordinary circumstance operating pressure is 4～30MPa) under given operating pressure, it is thinner to produce fogdrop diameter, spray momentum is big, cover multilayer multistage atomizing effect uniformly, even driving pressure is very low, in the situation of the above driving pressure of 1MPa, shower nozzle still can be realized atomizing effect preferably; The fine mist spray head that adopts multilayer multistage atomizing nozzle to make, substituted the assisted atomization structure that in the past had " mechanical obstacles " influence, make the thin water smoke droplet of shower nozzle ejection have very high momentum, the resistance that can break through flame flow reaches burning surface, and direct cooling combustion article reach the purpose of quick extinguishing; Adopt the fine mist spray head of multilayer multistage atomizing nozzle manufacturing, improved the momentum of shower nozzle ejection droplet, the spraying area coverage of single shower nozzle is increased, reduced the overall cost of needed shower nozzle quantity of unit are and fire extinguishing system.
This atomizer can be used for fire-fighting fire extinguishing, also can be used for other industrial circle, as flue gas scrub, depositing dust, pesticide spraying, food processing, the oxygen adjusting of fish and shrimp culture etc.Be not only applicable to the atomizing of water, be applicable to the atomizing of other low viscous flow body yet.
