Abstract

FIELD: heat and power industry; other industries; sprinkling devices used as the component part of the of the surfaces adhesive bonding.

SUBSTANCE: the invention may be used as the constituent heat-mass-exchange equipment at the direct contact between the gas and the liquid, in particular, in the industrial water cooling towers for cooling the circulating water. The water-cooling tower sprinkling device is made in the form of the module out of the layers of the polymeric mesh shells made cylindrical and arranged in all the horizontal layers in parallel to each other and welded on the ends of the module among themselves in the places of their touch. At that each mesh shell additionally contains in its volume the vane swirlers representing the polymeric cylinders, on the internal side of which there are vanes. Besides the vane swirlers may be rigidly fixed in the volume of the mesh shell by the welding or fixers. The invention solves the problem to increase effectiveness of the heat-mass exchange process.

EFFECT: the invention ensures the increased effectiveness of the heat-mass exchange process.

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 F 28 F 25/00, Sprinkler cooling tower / 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 provide contact between water and air flows directly on the surface of the sprinkler. 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 F 28 F 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 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. And also the disadvantages include the impossibility of turbulization of the droplet flow inside the sprinkler 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 cooling tower sprinkler in the form of a module of layers of polymer mesh shells made of cylindrical placed in all horizontal layers parallel to each other and welded at the ends of the module between them in contact, according to the invention, each mesh shell additionally contains the volume of the blade swirls, which are a polymer cylinder, on the inner side of which the blades are placed.

Also, the blade swirls can be rigidly fixed in the volume of the mesh shell by welding or clamps.

Figure 1 shows a General view of the block of the irrigator of the tower.

Figure 2 shows a General view of the blade swirl.

The cooling tower sprinkler is made in the form of a module from layers of polymer mesh shells 1, made cylindrical, placed in all horizontal layers parallel to each other and welded at the ends of the module to each other in contact, each mesh shell additionally contains in its volume bladed swirlers 2, which are a polymer cylinder 3, on the inside of which are placed the blades 4.

The sprinkler of the cooling tower operates 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. The paddle swirler prevents the free flow of the drip flow in the irrigation tube space, additionally turbulizes the ascending air flow, thereby intensifying the heat and mass transfer process.

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;

- Intensive turbulization of the air flow in the volume of the cooling tower sprinkler block.

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.
