Abstract
A diffusion impact type water-atomizing nozzle for extinguishing fire accident and cooling gas turbine, or used as moistener is composed of a main body with water inlet, small hole and conic water outlet arranged along central axis, and a diffuser under said main body and consisting of 3-6 U-shaped impact needles uniformly surrounding said water outlet to form an impact plane.
Description
Technical field
The present invention relates to a kind of atomising device or nozzle, relate in particular to a kind of diffusion impact type fine atomizer nozzle.
Background technology
According to different criteria for classifications, as the mode of water smoke generation, the pressure that water smoke produces etc., mist-generating nozzle has multiple different sorting technique.
The mode that water smoke produces generally includes: diffusion impact, pressure injection, gas atomization and injection are mutual.
Diffusion impact type fine atomizer nozzle is that metastable current are collided diffuser with middling speed, and diffuser resolves into the high momentum water smoke of various different sizes with current, compares with the mist-generating nozzle of other type, and its water droplet of 90% is all less than 600 microns.The working pressure range of bump nozzle in the market approximately clings to (250pis) from 7 crust (100pis) to 17.2.Concerning fire-fighting, the bump nozzle can be an enclosed automatic spray nozzle, as is applied in the fire extinguishing of category-A ordinary combustion; Also can be used in the deluge system of making all standing or region-type on the open-type nozzle, put out a fire as the category-B flammable liquid hazard.In the former technological document, the design of bump mist-generating nozzle comprises uses multiple tooth, sphere or spirality diffuser.The multiple tooth mist-generating nozzle of enclosed automatic spray that is used to put out a fire, part number is to have a detailed description in 5,392,993 the file in U.S. Fischer.It is to have a detailed description in 5,505,383 the file that spherical diffusion is clashed into open mist-generating nozzle part number in U.S. Fischer.For the spirality diffuser, comparatively speaking, in installation, maintenance process, can there be certain dangerous hidden danger.
The pressure injection mist-generating nozzle be with at a high speed the aperture of current by some, in nozzle interior vortex device just is being installed and is being assisted to decompose current.It is the principle of using drive nozzle that multiple mist-generating nozzle is arranged, and working pressure range is to 280 crust (4060pis) from 5 crust (70pis).Drive nozzle can be that enclosed starts separately or uses as open-type nozzle.Open-type nozzle can be used as on zone or all standing formula deluge system.The water droplet that the pressure injection mist-generating nozzle produces in high pressure range 90% all less than 150 microns.The enclosed automatic spray pressure injection nozzle that is used to put out a fire is to have a detailed description in 5,513,708 the file in the U.S. Sundholm patent No..Open type pressure injection nozzle has description in Sundholm International Patent Application WO 93/00962 (date is on July 20th, 1993).
Gas atomization mist-generating nozzle (also referring to two-fluid spray nozzle) is by Compressed Gas and in conjunction with the water generates water smoke that is arranged in position, spray-hole upper reaches mixing chamber.The actuating pressure of gas atomizing nozzle is approximately 5 crust (75pis), and the water droplet 90% of generation is less than 250 microns.Because open-type nozzle requires to guarantee that hydraulic pressure and gas pressure in the nozzle pipeline reach the mixing requirement, thus gas atomizing nozzle only limit to the zone cover or all standing deluge system in open-type nozzle on.The gas atomization mist-generating nozzle that is used to put out a fire is in 2,361,144 the file in the U.S. Loepsinger patent No. and the U.S. Papavergos patent No. is in 4,989,675 the file and U.S. Patent number is to have a detailed description in 5,014,790 the file.
Spray mutual mist-generating nozzle, accurately clash into generation water smoke by multiple current.To 7 crust (100pis), because the relative momentum that this nozzle produces is lower, so sphere of action only limits to be used on the portable nozzle cool off the operating pressure of this nozzle and dilution low volatility liquid fire from 3 crust (45pis).The mutual mist-generating nozzle of the injection that is used to put out a fire is in 2,310,798 the file in the U.S. Lewis patent No. and the U.S. Lee patent No. is to have a detailed description in 2,493,982 the file.
Summary of the invention
The present invention be intended to disclose a kind of cost low, easily install and the diffusion impact type fine atomizer nozzle of wide adaptability.
Technical solution of the present invention is achieved in that
A kind of diffusion impact type fine atomizer nozzle comprises main body and diffuser, and it is characterized in that has water inlet, aperture, delivery port on the axis of described main body from top to bottom, and the inner surface of delivery port is the circular cone inclined-plane; Diffuser is made up of 3～6 strikers that are evenly distributed in around the delivery port and curve the U type under main body, and U type one end is loaded on the main body bottom with impact style, and the other end gathers under main body, forms striking face jointly.
The striker of described diffuser is cylindrical or four prism type.
The angular range on described circular cone inclined-plane is 30 °～150 °, and this angle has determined the jet angle of thin water smoke.
Described hole diameter magnitude range is 0.5mm～8mm.
Distance between the extreme higher position of described diffuser striking face and the little hole exits is not more than 4 times of hole diameters.
The invention has the beneficial effects as follows conspicuous: whole nozzle is the design of single water route, and is simple in structure, thus easy for installation, and hole diameter is relatively large, can allow the impurity in the water to pass through, so not high for requirements in water quality, scalable.This mist-generating nozzle can be used for putting out category-A, category-B, C class and K class fire, also can be used for the environment that other need use thin water smoke, as humidifier, gas turbine cooling etc.
