Description

GO /// / ////////// U / V

The invention relates to industrial power engineering and can be used in cooling tower designs.

A known cooling tower including a sprinkler, a water collector and an air distributor disposed therebetween, the water flowing from the sprinkler is collected by trays and then directed in the form of jets into sockets located at the top of the air distributor from which it falls into the water collector without additional spraying.

A disadvantage of the known cooling tower is the insufficient cooling of the water, due to the low drop height.

The closest in technical essence is a cooling tower containing a casing made in the form of a frame with an elastic waterproof panel fixed to it, a piping for supplying chilled water placed in the casing, a water distributor with sprinklers and a sprinkler made in the lower part of the casing with a discharge pipe and above the collector - an air chamber with air inlet windows, the main discharge fan installed in the windows.

A disadvantage of the invention is the inefficient cooling of water.

An object of the invention is to increase the cooling efficiency of water.

This goal is achieved by the fact that the cooling tower is equipped with an additional fan located opposite the main one, as well as a three-way valve and additional pipelines located outside the case, while the valve is installed on the outlet pipe and is in communication with the pipe for supplying cooled water, placed in the case, of additional pipelines it is connected to the water collector and the water distributor, and the rest are connected to the air chamber, while the sprinkler is made in the form of two horizontally installed ontal nets and below them rows of vertical nets.

The invention is illustrated in the drawing, which shows a General view of the tower.

The cooling tower contains an air distributor made in the form of a chamber 1 with fans 2 and 3. The chamber 1 is installed in the water collector 4. The fans 2 and 3 are installed opposite each other and above the water surface of the water collector 4. A sprinkler in the form of a pipeline 5 with sprinklers 6 is installed above the water distributor and nets 7 and 8, to obtain a fine liquid for the purpose of additional cooling

two grids 7 are located horizontally under the sprinklers 6 at a distance of 50-60 mm due to the size of the tower. The nets 8 are mounted parallel to each other at a distance of 10-15 mm and vertically above the chamber 1. This distance is explained by the fact that, at a larger distance, water will flow and will not linger on the walls of the mesh. Nets can be

made of nylon or mesh nets, which should be no more than 1 mm. The sump 4 through the pipeline 9 through the pump 10 is connected to the pipeline 5 of the sprinkler. The chamber 1 has nozzles for

5 supply of waste water from the unit. Pipes 11 are located above the edge of the sump 4. The pipe 9 has a tee 12 for supplying water to the unit and to the cooling tower in the pipe 5. sprinkler from the sump 4.

0 Grids 7 and 8, pipeline 5 are fixed on racks 13, between which a dense material 14 is tightened, for example, a tarpaulin, the edge of which is located above the chamber 1 in the form of a container, thereby providing more

5 is effective cooling of water. Pipeline 9, for the purpose of additional cooling, is located inside the tank and connected to. sprinkler conduit 5, which is connected at the other end to a pump 15, which

0 water directly from the sump 4 is supplied to the sprinkler, during which the water is additionally cooled. The sump 4 has a 3-way valve for draining water at the location of the pipe

5 connected to the pumps 15. The chamber 1 in the lower part has slots 17 for supplying water from the chamber to the catchment 4.

The cooling tower works as follows.

0 When water is supplied to the pipeline 5, it enters the sprayers 6, then it enters the horizontal grids 7, as a result, finely dispersed liquid is obtained, then the sprays fall onto the vertical grids 8 located along the entire cross section of the tower. Water passing along vertical grids 8 is met with the air flow coming from fans 2 and 3 and under the influence of air flow

0 are broken up into smaller sprays and deposited on the mesh, forming a film in the mesh cells, while increasing the cooling area.

The cooled water then enters chamber 1, where it additionally enters chamber 1, where it additionally falls under the air stream from fans 2 and 3 and the water is finally cooled 5-10 ° below the temperature of the water supplied to the tower. And the water from the unit is supplied to

nozzles 1, gets into the air stream of fans 2 and 3 and is cooled. Since the chamber 1 is installed on the bottom of the catchment 4, through the slots 17, water seeps into the catchment 4 from where it passes through the pumps 10 and 15 to the irrigation pipe 5 and to the unit through the tee 12.

With this water intake from the catchment 4, additional cooling is provided by the location of the pipe 9 inside the tank, and when water is supplied through the pump 15, chilled water is also supplied to the sprinkler, thereby preventing scale formation in the sprinkler pipe 5.
