Description

The invention relates to energy and the chemical industry and can be used as an integral part of heat and mass transfer equipment with direct contact between gas and liquid, in particular in industrial cooling towers for cooling circulating water.

A tower cooler sprinkler is known in the form of a module made of layers of perforated pipes parallel to each other made of thermoplastic material welded at the ends of the module to each other in contact, the pipe end sections being made without perforation, and the cross section of the pipe end section is broadened relative to the cross section of the perforated pipe section. [RF patent No. 2141616, IPC F28F 25/00, IRRIGATING COOLERS / Samoilov G.A. and others. Claimed 11/11/1997. Publ. 11/20/1999. Bull. No. 32].

The disadvantage of this cooling tower sprinkler is the possibility of free penetration of the drip water flow inside the perforated pipes, which will not ensure its proper interaction with the air flow, the small contact surface of the cooled circulating water with air and the impossibility of turbulization of the upward air flow in the sprinkler volume.

The closest technical solution to the proposed invention (prototype) is the cooling tower sprinkler in the form of a module made of layers of polymer honeycomb pipes, in which the pipes are cylindrical, placed in all layers parallel to each other and welded at the ends of the module between them in contact. Pipes in adjacent layers are staggered relative to each other. [RF patent No. 2141617, IPC F28F 25/08, / Bykovets V.P. and others. Claimed 08/18/97. Published on November 20, 1999. Bull. No. 32].

The main disadvantage of the design is also a small heat and mass transfer surface. This drawback leads to a decrease in the contact of the air flow with the water flow directly on the surface of the sprinkler, which reduces the efficiency of the heat and mass transfer process, as well as the impossibility of turbulization of the ascending air flow in the sprinkler volume.

The invention solves the problem of increasing the efficiency of the heat and mass transfer process.

This problem is solved due to the fact that the cooling tower sprinkler is composed in the form of a module of layers of polymer mesh shells made of cylindrical, arranged in all vertical layers parallel to each other and firmly welded at the ends of the module in contact, and, according to the invention, each mesh the shell additionally contains in its volume a swirl element, which is a polymer rod with blades, each of which is made in the form of a sector of a circle, while swirl elements getting a ratio of 2 to 3 to 2 for each subsequent row of vertically arranged lattice shells.

Also, the swirling elements can be perforated.

Figure 1 shows a General view of the sprinkler of the cooling tower.

Figure 2 shows the installation diagram of the swirl element in the volume of the mesh shell.

The cooling tower sprinkler is composed in the form of a module from layers of polymer mesh shells 1 made of cylindrical, placed in all vertical layers parallel to each other and firmly welded at the ends of the module to each other in contact, and each mesh shell additionally contains a swirl element in its volume, which is polymer rod 2 with blades 3, each of which is made in the form of a sector of the circle, while the swirl elements are set in a ratio of 2 to 3 to 2 for each subsequent a row of vertically placed mesh shells.

Also, the swirling elements can be perforated.

The sprinkler of the cooling tower operates as follows.

Recycled water is supplied to the sprinkler of the cooling tower, and under the influence of mass forces passes through it, flowing in a thin stream along polymer cellular pipes. The swirling element prevents the free passage of the drip flow in the pipe space of the irrigator, additionally turbulizes the ascending air flow, thereby intensifying the heat and mass transfer process.

The main advantages of the proposed design of the tower sprinkler include the following:

- the effectiveness of the design, by eliminating the possibility of free penetration of the drip stream in the pipe space without contact with the surface of the sprinkler;

- structural strength due to the high damping ability of the mesh shells;

- due to the small mass of the sprinkler, the supporting structures of the support frame can be significantly facilitated;

- turbulization of the air flow inside the tower sprinkler unit.

The invention meets the criterion of "industrial applicability" and can be used in the energy and chemical industries as an integral part of heat and mass transfer equipment with direct contact between gas and liquid, in particular in industrial cooling towers for cooling circulating water.
