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, Cooling tower sprinkler / Samoilov G.A. and etc; declared 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 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 etc.; declared 08/18/97; publ. 11/20/99; Bull. No. 32].

The main drawback of the design is the possibility of free penetration of a drip water stream without its contact with the irrigator when installing the module 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 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 sprinkler of cooling towers 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 contact, according to the invention, as a part of each row of vertically placed mesh shells installed horizontally lying corrugated pipes in a ratio of 1 to 2 to 1 for each subsequent row of vertically placed mesh shells.

The drawing shows a General view of the irrigation tower.

The cooling tower sprinkler is composed in the form of a module from layers of polymer mesh shells 1 made of cylindrical, arranged in all vertical layers parallel to each other and welded at the ends of the module in contact, and horizontally lying corrugated pipes 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.

Sprinkler cooling towers works 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. Corrugated pipes impede the free passage of the drip stream in the pipe space of the irrigator, additionally turbulating the ascending air stream, thereby intensifying the heat and mass transfer process, which helps to increase the contact time of water droplets with the air stream.

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 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.
