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 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.; 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 disadvantages include the impossibility of turbulization of the droplet flow inside the sprinkler block.

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 three-section cooling tower sprinkler in the form of modules of 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, is composed of three modules: in the lower module each mesh shell additionally contains in its volume bladed swirls, which are a polymer cylinder, on the inner side of which there are blades; the middle module contains vertical layers of horizontally lying mesh shells located alternately with vertically mounted corrugated sheets representing a sinusoid in cross section, and the corrugations of the corrugated sheets are horizontal; in the upper module, each row of vertically placed mesh shells contains horizontally lying corner profile elements in a ratio of 1 to 2 to 1 for each subsequent row of vertically placed mesh shells.

In FIG. a general view of a three-section cooling tower sprinkler is presented.

A three-section cooling tower sprinkler in the form of modules 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 between them at the points of contact, is composed of three modules: in the lower module, each mesh shell additionally contains the volume of the blade vortexes 4, which are a polymer cylinder, on the inner side of which the blades are located; the middle module contains vertical layers of horizontally lying mesh shells, located alternately with vertically mounted corrugated sheets 3, which are a sinusoid in cross section, and the corrugations of the corrugated sheets are horizontal; in the upper module, each row of vertically placed mesh shells has horizontally lying corner profile elements 2 in a ratio of 1 to 2 to 1 for each subsequent row of vertically placed mesh shells.

Three-section irrigation tower works 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 through polymer cellular pipes. Corner profile elements prevent the free passage of the drip flow in the pipe space of the irrigator and further contribute to the uniform distribution of the drip flow throughout the entire volume of the irrigator. The second layer has a high scattering power, so that the droplets of the cooled water are smaller and cool faster. The lower layer, due to the presence of paddle swirlers, swirls the upward air flow in the sprinkler volume, which helps to increase the contact time of water droplets with the air flow, thereby intensifying the heat and mass transfer process.

From a practical point of view, the proposed design of the cooling tower sprinkler has the following advantages:

- the design of the mesh shell contributes to a uniform film-drop distribution of liquid over the surface of the sprinkler, as well as the self-cleaning process (provided that the inclusions in the circulating water to the polymer products have a low adhesive ability);

- effective cooling of the recycled water of industrial enterprises, due to the high contact surface of the phases, will prevent the discharge of process water into natural sources and minimize the recharge of the water circulation system, which will significantly improve the environmental situation of industrial and surrounding areas;

- the sprinkler unit is able to withstand large static loads, due to the high damping ability of the mesh shell;

- in comparison with wood and asbestos-cement sprinklers, the developed designs have a longer service life, which is determined by the properties of the polymeric material used to manufacture the mesh shell;

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

- the design of these irrigators due to the installed inserts additionally turbulent the air flow in their volume, and, therefore, increase the intensity of the heat and mass transfer process.

- reducing the energy intensity of the heat and mass transfer process, namely, reducing the power consumption of the fan is due to the relatively low coefficient of aerodynamic drag of the sprinkler based on polymer honeycomb pipes;

- durability.

Thus, the use of cooling tower irrigators in the chemical and oil refining industry will significantly increase the efficiency of the heat and mass transfer process for cooling the recycled water of industrial enterprises, and at the same time, reduce the volume of pollution of water resources, reduce the dependence of industrial enterprises on natural sources, minimizing recharge of the water circulation system and allow to carry out the heat and mass transfer process of cooling circulating water using cooling towers with less energy Atrato.
