Abstract

The cooling tower sprinkler, made in the form of a module from layers of cylindrical polymer cellular pipes welded at the ends of the module to each other in places of contact, characterized in that the pipes in the module are bent with a bend radius equal to their diameter.

Description

The utility model relates to the energy and chemical industries and can be used as a contact device for heat and mass transfer equipment, 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 pipe end sections are 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, cooling tower sprinkler / 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 possibility of free penetration of a drip water stream inside perforated pipes, which will not ensure its proper interaction with the air stream, as well as a small contact surface.

The closest technical solution to the proposed utility model (prototype) is the cooling tower sprinkler in the form of a module from layers of polymer cellular 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 at the points of 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 disadvantage of the design is also a small contact surface. This drawback leads to a decrease in heat and mass transfer of the sprinkler, as a result of which the efficiency of the process is reduced.

The objective of the utility model is to create a device - an irrigator of cooling towers with the following technical result: 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 cylindrical polymer cellular pipes bent with a bend radius equal to their diameter and welded at the contact points of the end ends to form a stiffness membrane.

The figure shows a General view of the sprinkler of the cooling tower.

The cooling tower sprinkler is a module of polymer cellular pipes 1, while the polymer mesh cellular pipes 1 in the module are bent with a bend radius 2 equal to their diameter and welded at the contact points of the end ends with the formation of a stiffness membrane 3.

The sprinkler of the cooling tower operates as follows.

During operation of the cooling tower, the cooled circulating water I is supplied to the sprinkler. The sprinkler, being a contact device, promotes uniform drip and film flow along the surface of the mesh cellular pipes 1 of circulating water I. In this case, the cooling ascending air stream II interacts with circulating water I with a decrease in the temperature of the latter.

The efficiency of the utility model is determined by the fact that:

- polymer mesh cellular pipes are made bent with a bend radius equal to their diameter and welded at the contact points of the end ends with the formation of a stiffness membrane, thereby eliminating the possibility of free penetration of the droplet stream in the pipe space without contact with the surface of the sprinkler;

- due to the high damping ability of the mesh shells, the structural strength increases by 1.8 times.

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