Description

The invention relates to heat and mass transfer apparatus, to tower and fan cooling towers.

The closest technical solution to the proposed utility model (prototype) is a water trap containing corrugated pipes of thermoplastic material, which is a module of pieces of corrugated pipes welded along the end surface of each other, located in the module parallel to each other, and the corrugated pipes can be located as in staggered and rectangular and oriented at an angle of 25-80 ° to the horizon [RF patent for utility model No. 36496. Application October 3, 2002, publ. 03/10/2004].

The main drawback of the design is the low efficiency of water capture, due to both a low aerodynamic drag and an insufficient change in the velocity vector of the ascending vapor-gas flow.

The invention eliminates this drawback and improves the efficiency of catching drops from an upward combined-gas flow in the process of cooling the recycled water of industrial enterprises.

This problem is solved by using the cooling tower sprinkler in the form of a module from layers of polymer cellular pipes, arranged in all layers parallel to each other and welded at the ends of the module in contact, and at the ends of the module, the ends of the polymer cellular pipes are conical in shape diffusers with a height of 0.2-0.5 of their diameter and an angle of 30-60 ° relative to their central axis, as a water trap for cooling towers [RF patent No. 2243468, IPC F28F 25/08, Sprinkler cooling tower / Storozhenko V.N. and etc; Stated April 29, 2003; Publ. 12/27/2004].

The drawing shows a General view of the sprinkler of the cooling tower, used as a water trap cooling tower.

The cooling tower sprinkler in the form of a module made of layers of polymer honeycomb pipes 1, placed in all layers parallel to each other and welded at the ends of the module in contact, and at the ends of the module, the end sections of the polymer honeycomb pipes are shaped like a conical diffuser with a height of 0.2 -0.5 of their diameter and an angle of 30-60 ° relative to their central axis.

The invention works as follows.

An ascending vapor-gas stream saturated with water droplets passes through the sprinkler, repeatedly changing the velocity vector, which contributes to the deposition of water droplets on its surface, which then flow back to the cooling tower under the influence of mass forces.

Thus, the design of this water trap increases the efficiency of water capture, which contributes to the improvement of the environmental situation of industrial and adjacent areas.

The invention meets the criterion of "industrial applicability" and can be used for droplet collection during cooling of the recycled water of industrial enterprises using cooling towers.
