Description

" one

The invention relates to a device for spraying liquids and can be used for the purpose of cooling a liquid by spraying followed by the use of a cooled liquid when cooling waste steam in turbines.

The purpose of the invention is to improve the dispersion and uniformity of splashing liquid.

1 shows a spray device; figure 2 - section aa in figure 1.

The device comprises a housing 1 s, a cylindrical chamber 2 and a suction opening 3 coaxial with it and a nozzle 4 for supplying liquid. The end 5 of the nozzle 4 is made of a larger diameter, plugged from the end and inserted into the chamber 2. At the end of the 5 nozzle 4 hollow protrusions 6 and 7 are made, mating with the inner surface of chamber 2.. Windows 8 and 9 are made in the walls of the hollow projections 6 and 7 tangentially directed to chamber 2. At the end of 5 nozzle 4, there are screw-shaped blades 10 and 11 connected to the surface — chambers 2, one of which is 256757-2.

The main sides of each blade 10 and II are connected to the lower base of one of the projections 6, 7 on the side of windows 8, 9, and the other to the upper base of the other protrusion 7.6c of the opposite side. The height of windows 8 and 9 is made larger than their width.

The device works as follows.

in a way. .

Fluid is supplied through the nozzle 4 and through tangentially directed windows 8 and 9 is directed to the screw vanes 10 and 11. The fluid flow twists and leaves the cavity of the housing 1 through the opening 3 in the form of a full cone. Pre-formation of fluid flow by windows 8 and 9 and the surfaces of end 5 of nozzle 4

and the inner surface of the chamber 2 in the form of a film provides an increase in the degree of dispersion of the liquid, which increases the efficiency of its cooling, the design of the device.

It also ensures the stabilization of the pressure of the incoming liquid, which contributes to the uniformity of its splashing.
