RU2481134C1 - Sprayer - Google Patents

Abstract

FIELD: process engineering.

SUBSTANCE: invention relates to sprayers. Sprayer comprises hollow cylindrical case with vortex flow spreader. Case upper section has outer thread for connection to fluid feed distribution pipeline union. Case lower section has outer thread for connection to vortex flow spreader via iron ring. Outer porous surface of spreader is attached to said ring. Spreader surface is shaped to truncated ellipsoid of revolution. Note here that larger axis of its frontal projection separated spreader inner space from said elliptical space. Smaller axis of frontal projection is aligned with inner cylindrical space. Said outer porous surface is equidistant with inner space elliptical space while casing has inner cylindrical chamber. Said chamber serves to feed fluid and accommodates swirler. Said swirler is composed of a sleeve with large-pitch trapezoidal-cross-section outer thread. Said swirled is screwed on rod secured via gauze filter to said case.

EFFECT: higher efficiency of spraying.

Description

The invention relates to techniques for spraying a liquid.

The closest technical solution to the claimed object is the nozzle according to patent RU No. 2427402, A62C 31/02 (prototype), containing a hollow cylindrical body with a swirl divider.

The disadvantage of the prototype is that the known design does not allow to achieve a given distribution of the flows of fine droplets on the irrigation surface of the required area without increasing the flow rate of the liquid.

The technical result is an increase in the efficiency of finely dispersed liquid spraying.

This is achieved by the fact that in the nozzle containing a hollow cylindrical body with a swirl flow divider, an external thread is made in the upper part of the body for connecting to the nozzle of the distribution pipe for supplying fluid, and an external thread is made in the lower part of the body for connection with the swirl flow divider by means of a clip made in the form of a ring to which an external porous surface of the divider is attached, made in the form of a truncated ellipsoid of revolution, with the major axis of its frontal The projection separates the inner cylindrical cavity of the divider from the elliptical cavity, the small axis of the frontal projection of which is coaxial with the inner cylindrical cavity, and the outer porous surface is equidistant to the elliptical surface of the inner cavity, and in the case there is an inner cylindrical chamber that serves to supply fluid, and in which it is installed coaxially and with a gap relative to its inner side surface, a swirler made in the form of a sleeve with a screw external thread with a large pitch tr petsiidalnogo profile, and fastened by the internal thread on the rod which is secured at its upper part through a strainer to the housing.

The drawing shows a nozzle diagram.

The nozzle contains a hollow cylindrical body 1, in the upper part of which an external thread is made for connection to a fitting (not shown) of a distribution pipe for supplying fluid, and in the lower part of the body, an external thread is made for connection with a vortex flow divider 8 by means of a clip 9 made in the form of a ring to which an external porous surface 10 is attached, made in the form of a truncated ellipsoid of revolution, the major axis of its frontal projection separating the inner cylindrical the second cavity 11 of the divider 8 from the elliptical cavity 12, the small axis of the frontal projection of which is coaxial with the inner cylindrical cavity 11, and the outer porous surface 10 is equidistant to the elliptical surface of the inner cavity 12.

In the housing 1 there is an inner cylindrical chamber 4, which serves to supply fluid. To create the greatest effect of the formation of a finely divided continuous phase of the sprayed liquid in the cylindrical chamber 4, coaxially mounted with a gap 7 relative to the inner side surface of the chamber 4, a swirler 3, made in the form of a sleeve with a screw external thread with a large pitch of a trapezoidal profile, and fixed by internal thread 6 on the rod 2. The rod 2 is fixed in its upper part by means of a strainer 5 to the housing 1.

The nozzle is as follows.

When the fluid is supplied to the housing 1 under the influence of a pressure drop of 0.4 ... 0.8 MPa in the chamber 4, due to the swirler 3, vortex flows of fluid are created, which flow into the vortex flow divider 8, and when the expanding fluid flows expire through the gap 7 in series, with the internal cavities of the divider by the cylindrical cavity 11 and the elliptical cavity 12, a fan-shaped gas-liquid flow in the form of a shroud is formed, i.e. a mechanism for crushing liquid droplets is implemented.
