Description

The utility model relates to devices for cooling water in a circulating water supply system, and more particularly to a water trap for fan and tower cooling towers. It can also be used in other devices where there is a need to capture liquid from vapor-air mixtures.

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 in a rectangular order and oriented at an angle of 25-80 ° to the horizon (RF Patent for utility model No. 346496 F28F 25/02 Application. 3.10.2002, publ. 10.03.2004).

The main disadvantage of the design is the low efficiency of water capture.

The objective of the utility model is to increase the efficiency of water capture.

This problem is solved due to the fact that the water trap containing pipes of thermoplastic material, which is a module of pipe segments welded along the end surface of each other, located in the module parallel to each other, and the pipes can be located

both staggered and in rectangular order and oriented vertically or at an angle to the horizontal, according to a utility model, each pipe segment contains in its volume an axial twisting device made in the form of two single-running screws with one central axis and a height of the crest of the first 0.5 and the second 0.05 ÷ 0.4 of the inner diameter of the pipe.

Also, each pipe segment in its volume at the output section may contain a catching element made in the form of a straight or inclined hollow truncated cone.

Figure 1 presents a General view of the water trap.

Figure 2 presents a vertical pipe segment with a twisting device and a catching element.

The water trap contains pipes made of thermoplastic material and is a module of pipe segments 1 welded along the end surface of each other, arranged parallel to each other in the module, and the pipes can be staggered or rectangular and oriented vertically or at an angle to the horizontal and each pipe segment contains in its volume an axial twisting device 2, made in the form of two single-running screws with one central axis and a height of the ridge of the first 0.5 and second 0.05 ÷ 0.4 internally th pipe diameter.

Also, each pipe segment in its volume at the output section may contain a catching element made in the form of a straight or inclined hollow truncated cone 3.

A water catcher works as follows.

The water-air flow enters from the bottom of the water trap, where, getting on the swirl element, made in the form of a screw, acquires a rotational movement. Under the action of centrifugal force, water droplets are thrown to the wall, where, coarsening, flow down the surface of the pipe, and finely dispersed dropping liquid quickly gets into the peripheral zone of the pipe due to the additional axial screw. Further, the gas-vapor stream, passing the separation zone, enters the trapping element, where, due to the pressure drop, the condensation process occurs, the droplet liquid formed under the action of inertial forces is discarded to the inner surface of the truncated cone and flows down. The outer conical surface of the collecting element creates additional resistance to the peripheral layer of the stream with a high content of droplet liquid.

The main advantages of the catcher are:

- simplicity of design;

- high efficiency of the process of capturing water droplets in an upward gas-liquid flow;

- relatively low aerodynamic drag;

Thus, the use of this design catcher in the chemical industry is promising.
