Description

The utility model relates to the energy and chemical industries 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 etc; Stated 11/11/1997; Publ. 11/20/1999 Bull. No. 32].

The disadvantage of this sprinkler of the cooling tower is the possibility of free penetration of the droplet stream of water inside the perforated pipes, which will not ensure its proper interaction with the air stream. And also the impossibility of turbulization of the droplet stream of water in the volume of the irrigator block.

The closest technical solution (prototype) is the cooling tower sprinkler in the form of a module of layers of polymer cellular pipes, in which the pipes are cylindrical, placed in all layers

parallel to each other and welded at the ends of the module with each other in places of contact. Pipes in adjacent layers are staggered relative to each other [RF Patent No. 2141617, IPC F28F 25/08, / Bykovets V.P. and etc.; Stated August 18, 1997; Published on November 20, 1999. Bull. No. 32].

The main drawback of the design is the possibility of free penetration of a drip water stream without contacting it with an irrigator when the module is installed in a cooling tower with vertical placement of polymer cellular pipes. This drawback leads to a decrease in the contact of the air flow with the water flow directly on the surface of the sprinkler, as a result of which the efficiency of the heat and mass transfer process is reduced. And also the impossibility of turbulization of the droplet stream of water in the volume of the irrigator block.

The utility model solves the problem of increasing the efficiency of the heat-mass transfer process.

This problem is solved due to the fact that the cooling tower sprinkler in the form of a module from layers of polymer mesh shells made cylindrical, placed in all vertical layers parallel to each other and welded at the ends of the module between them, in accordance with the utility model, vertically in each row placed mesh shells installed horizontally lying grooved profile elements in a ratio of 1 to 2 to 1 for each subsequent row of vertically placed mesh shells.

In FIG. shows a general view of the cooling tower sprinkler.

The cooling tower sprinkler is composed in the form of a module of layers of polymer mesh shells 1 made of cylindrical, placed in all vertical layers parallel to each other and welded at the ends of the module in contact, and horizontally lying grooved profile elements are installed in each row of vertically placed mesh shells 2 in a ratio of 1 to 2 to 1 for each subsequent row of vertically placed mesh shells.

The sprinkler of the cooling tower operates as follows.

Recycled water is supplied to the sprinkler of cooling towers and, under the influence of mass forces, passes through it, flowing in a thin stream along polymer cellular pipes. The grooved profile elements prevent the free passage of the droplet flow in the irrigation tube space, additionally turbulizing the ascending air flow, thereby intensifying the heat and mass transfer process, which helps to increase the contact time of water droplets with the air flow.

The main advantages of the proposed design of the cooling 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;

The utility model 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.
