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.

Known sprinkler tower in the form of a module of layers of parallel perforated pipes of thermoplastic material, welded at the ends of the module with each other in contact, and the end sections of the pipes are made without perforation, and the cross section of the end section of the pipe is broadened relative to the cross section of the perforated pipe section [ RF patent No. 2141616, IPC F28F 25/00. IRRIGANT OF THE COOLING HOUSE / Samoilov G.A. and etc; claimed 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 drip water stream inside the perforated pipes, which will not ensure its proper interaction with the air stream.

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 to each other 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.; claimed 08/18/97; published on 11/20/99. 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 makes it impossible to contact the air stream with the water stream directly on the surface of the irrigator, i.e. does not lead to the formation of a film on its surface and as a result, the efficiency of the heat and mass transfer process is reduced.

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 made in the form of a module from layers of polymer mesh shells, in which the shells are cylindrical, placed in all layers parallel to each other and welded at the ends of the module between each other in contact, and the module in its volume additionally contains a similar small module of layers of polymer mesh shells arranged in all layers parallel to each other, oriented at an angle of 90 ° to the polymer mesh shells of the module containing them. Also, the small module can be rigidly fixed in the volume of the containing module by welding.

Figure 1 shows a longitudinal section of the sprinkler of the cooling tower.

Figure 2 shows a cross section of the sprinkler of the cooling tower.

The cooling tower sprinkler is made in the form of a module from polymer mesh shells 1. In its volume it contains a similar small module 2, which is also made of polymer mesh shells oriented at an angle of 90 ° to the polymer mesh shells of the module containing them.

The sprinkler of the cooling tower operates as follows.

Recycled water or other liquid medium is fed to the sprinkler of the cooling tower and, under the influence of mass forces, passes through it, flowing in a thin stream along the polymer cellular pipes. The small module prevents the free passage of the drip stream in the tube space of the irrigator, additionally it turbulizes, and helps increase the contact time with the air stream. In turn, the mesh shells framing the small module, due to their high damping ability, give rigidity to the entire structure.

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 framing the small module.

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.
