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.

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, IRRIGATING COOLERS / 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 droplet stream of water inside the perforated pipes, which will not ensure its proper interaction with the air stream. As well as the small contact surface of the cooled circulating water with the rising air.

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.; claimed 08/18/97; published on 11/20/99. 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.

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

This problem is solved due to the fact that the drip-film sprinkler of the cooling tower is presented in the form of a module from layers of polymer horizontally lying parallel to each other mesh shells made cylindrical and welded at the ends of the module between them in contact, and, according to a utility model, vertical layers of horizontally lying mesh shells are arranged alternately with vertically mounted corrugated sheets representing a sinusoid in cross section.

Also, the number of corrugations of the corrugated sheet may coincide with the number in the horizontal layers of horizontally lying mesh shells; the radius of the corrugations of the corrugated sheets can be equal to the radius of the mesh shells that are installed at the vertices and depressions of the corrugated sheet.

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

Figure 2 shows a General view of the sprinkler of the cooling tower with a radius of corrugation of corrugated sheets equal to the radius of the mesh shells.

The drip-film sprinkler of the cooling tower is a module of layers of polymer horizontally lying parallel to each other mesh shells 1, made cylindrical and welded at the ends of the module between them in contact, and the vertical layers of horizontally lying mesh shells are located alternately with vertically mounted corrugated sheets 2, which are a sinusoid in cross section.

Also, the number of corrugations of the corrugated sheet may coincide with the number in the horizontal layers of horizontally lying mesh shells; the radius of the corrugations of the corrugated sheets 3 can be equal to the radius of the mesh shells that are installed in the vertices and depressions of the corrugated sheet.

The sprinkler of the cooling tower operates as follows.

Recycled water is fed to the tower sprinkler and, under the influence of mass forces, flows down the surface of corrugated sheets and fibers

mesh shells, which, in turn, additionally serve as drop eliminators.

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

- design efficiency, due to the combination of mesh shells and corrugated sheets, by increasing the effective heat and mass transfer surface, by eliminating the possibility of free penetration of the droplet flow in the tube space without contact with the surface of the sprinkler;

- the sprinkler block has high operational and technical characteristics in comparison with other designs (sprinkler from corrugated pipes, etc.);

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

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