Description

The utility model relates to a power system and can be used in installations for evaporative cooling of recycled water of industrial enterprises to ensure uniform distribution of water over the irrigation area.

A spray device is known that contains a supply pipe and racks adjacent to them with a convex-concave streamlined reflector made with waterdrops-weirs, alternating around a circle on its concave part, with waterdrops-webs located adjacent to each other and limited by vertical thresholds (see Certificate No. 5740). , publ. 1998).

The disadvantage of this spray device is the low efficiency of the liquid spray due to the underdeveloped (flat) spray torch.

The closest claimed technical essence is a universal spray device containing a supply pipe with adjoining racks and a streamlined reflector adjacent to the racks, made in the form of a cone facing the apex of the inlet pipe, moreover, thresholds of different sizes are made in a checkerboard pattern along concentric circles on the surface of the streamlined reflector height and with an inclination to the generatrices of the cone of the streamlined reflector at an angle ranging from 90 ° to 180 ° (see RF Patent No. 2237523, IPC ⁷ V05V 1/26, publ. 2004).

The disadvantage of the prototype is the complexity of the manufacture of the structure, due to the execution on the outer surface of the cone of the streamlined reflector of a large number of thresholds of different heights and with different angles of inclination, as well as triangular protrusions.

The objective of the utility model is to increase the efficiency of spraying by creating a volume torch, as well as simplifying the manufacture of the structure.

The solution to the problem is a spray device containing a conical reflector having thresholds facing the inlet pipe. The thresholds are made in the form of continuous protrusions located at a distance from each other, along

concentric circles, along the entire length of the generatrix of the cone, with an internal angle ∠α in the range of 80-120 °, and the protrusions have a triangular section, one side of which is located at right angles to the direction of fluid motion, while the distance between the protrusions refers to their height: s / h = 2.5 ÷ 3.5, where

s is the distance between the protrusions

h is the height of the protrusions.

While the ratio between the height of the protrusion and the thickness of the liquid layer flowing down the surface of the reflector is: h / H = 1.0 ÷ 1.2, where

h - the height of the protrusions

H is the thickness of the layer flowing down the surface of the reflector, liquid.

The implementation of the thresholds in the form of solid protrusions and their location at a distance from each other along concentric circles along the entire length of the generatrix of the cone, allows to increase the efficiency of spraying due to the creation of a volumetric torch, and simplifies the manufacture of the structure.

An image of a spray device is shown in FIGS. 1-3.

The spray device contains a conical reflector 1 facing the inlet pipe 2 having thresholds in the form of solid protrusions 3.

The spray device operates as follows.

The flow of water flows from the inlet pipe 2 to the conical reflector 1 and spreads over its surface and meets the protrusions 3. When flowing around the protrusions 3, the liquid layer partially collapses and breaks off the surface (Figs. 1-3), creating a volume torch.

Thus, the spray device allows for a high efficiency of liquid spray, increasing the interface surface, and also to increase the height of the dispersed layer thereby increasing the time of contact of the liquid with air. All this contributes to the intensification of the heat transfer process.
