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 cooling tower sprinkler is the impossibility of turbulization of the drip water flow in the volume of the sprinkler 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-mass transfer process.

This problem is solved due to the fact that the heat and mass transfer nozzle of cooling towers is made in the form of a module from layers of polymer mesh shells made of cylindrical placed in all vertical layers parallel to each other and welded at the ends of the module between them in contact, and spacers are installed on the bottom surface of the module insertion.

Also, each spacer insert can be made in the form of a blade swirler, which is a polymer cylinder with blades on the inner or outer surface.

Figure 1 presents a General view of the heat and mass transfer nozzles of cooling towers.

Figure 2 presents the bottom view of the nozzle.

Figure 3 shows a method of installing nozzle modules in a cooling tower.

The heat and mass transfer nozzle of cooling towers is made in the form of a module from layers of polymer mesh shells 1, made cylindrical, placed in all vertical layers parallel to each other and welded along the ends of the module at the contact points, and the distance inserts 2 are installed on the bottom surface of the module. The distance insert can be made in the form of a blade swirler, which is a polymer cylinder with blades on the inner or outer surface.

Heat and mass nozzle cooling towers operates as follows.

Recycled water is supplied to the nozzle, and under the influence of mass forces passes through it flowing in a thin stream through polymer cellular pipes. The distance inserts form a gap between the modules mounted on top of each other and prevents the free flow of the drip flow in the pipe space of the sprinkler, turbulent upward air flow.

The main advantages of the proposed design of heat and mass transfer nozzles of cooling towers 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 nozzle;

- structural strength due to the high damping ability of the mesh shells;

- turbulization of the air flow inside the nozzle module.

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.
