Abstract

The utility model discloses an atomizing nozzle for spray system, comprising an eddy flow chamber, a diverging pattern nozzle orifice and a water inlet pipe, wherein the eddy flow chamber is of a hollow globe, a bushing connected with the spherical eddy flow chamber is arranged outside the diverging pattern nozzle orifice, an aeration passage is formed between the bushing and the diverging type nozzle orifice, a plurality of air leading ports communicated with the aeration passage are arranged on the lower wall of the bushing, and a diverging pattern waterproof board corresponding to the air leading ports is arranged on the bushing for easy air leading. The utility model is provided with the spherical eddy flow chamber to enable the liquid entering the eddy flow chamber to have good acceleration and to have higher flow speed even under smaller hydraulic pressure. Additionally, an air inlet device is arranged beside the nozzle orifice to ensure contact and impacting effect between sprayed liquid drips and air, thereby achieving good atomizing effect.

Description

Self-priming high-efficient atomizing nozzle

Technical field

The utility model relates to a kind of spray equipment, especially relates to the atomizer in the spray equipment, is mainly used in packed tower, the hollow-spraying-tower of chemical industry, oil refining industry, and the cooling tower of recirculated water field and the spray column of tank body spray cooling.

Background technology

At present, it all is to rely on the effect of elevated pressures to make liquid reduce logical sectional area by nozzle the time further to increase flow velocity that the shower nozzle of liquid spraying device has multiple, early stage nozzle, and clashes into pulverizer plate liquid is atomized, but this atomizing type atomizing effect is bad, and energy loss is bigger.

Chinese patent CN87214261U discloses a kind of " spiral-flow type shower nozzle ", it is by the tape entry pipe, trunnion, the sprayer body in shower nozzle chamber and nozzle are formed, wherein its shower nozzle chamber is a cylinder, top is the circular arc top, inlet tube is connected with shower nozzle chamber tangent line, tangentially flow in the shower nozzle chamber behind the inlet tube raising flow velocity of liquid by undergauge and form eddy flow, reduce logical sectional area through conical nozzle then and further increase flow velocity, spray out through conical outlet again, forming atomizing, still, is cylinder shower nozzle chamber because it adopts, when liquid forms eddy flow therein, fail well to be quickened, cause the flow rate of liquid in exit relatively low, atomizing effect is bad, when intake pressure was lower than 0.1MPa, atomizing effect was more undesirable.

Chinese patent CN2391688Y discloses a kind of " tangent line water inlet atomizer ", it is by being provided with the deflection cone of a taper revolving body in the shower nozzle chamber, make the movement locus of the current that enter shower nozzle regular more, the flow velocity of current each point in the shower nozzle die cavity and dynamic pressure, static pressure are changed have more designability, thereby the raising atomizing effect, still, this design still fails effectively to improve the flow velocity of liquid in the shower nozzle chamber, thereby influenced atomizing effect, can not be applicable to the occasion that hydraulic pressure is lower.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of shower nozzle that can obtain better atomizing effect under the situation of low intake pressure is provided.

The purpose of this utility model is achieved in that

A kind of self-priming high-efficient atomizing shower nozzle, comprise spin chamber, trumpet type spout and water inlet pipe, water inlet pipe is tangent line with the spin chamber and is connected, the axis of water inlet pipe is vertical mutually with trumpet type spout axis, wherein said spin chamber is the spherical shape of hollow, be provided with the ring set that is connected with the spherical shape spin chamber in trumpet type spout outside, between ring set and trumpet type spout, form venting channels, have some air-vents on the bottom perisporium of ring set, air-vent is communicated with venting channels, and corresponding air-vent position is provided with the horn-like splash guard of being convenient to air inducing on ring set.

Operation principle of the present utility model is as follows: liquid enters the spherical shape spin chamber through the water inlet pipe tangent line, in spheroid, form eddy flow, because the eddy flow radius is more and more littler, the flow velocity of liquid is well quickened, when liquid was spouting through the trumpet type spout, liquid at a high speed produced negative pressure at the spout place, and a large amount of air enters venting channels at the effect lower edge of negative pressure air-vent, form the strong bump of high speed with the liquid that ejects, make drop pulverize and be atomized.

Because the utility model has designed the spin chamber of spherical shape, make being quickened preferably of the liquid that enters the spin chamber, even if when inlet hydraulic is less, also can obtain higher flow velocity; In addition, designed air intake structure in that spout is other, guaranteed contacting and impact effects of the drop that ejects and air, thereby obtained atomizing effect preferably; Moreover the drop after the horn-like splash guard of design can be avoided atomizing as far as possible enters air-vent, has guaranteed air inflow, thereby has guaranteed the continuation of atomizing effect.
