Description

Technical Field

[0001] The utility model relates to the technical field of closed cooling towers, in particular to a high-efficiency closed cooling tower. Background Art

[0002] A closed cooling tower is a tower that places a tubular heat exchanger inside the tower. The cooling effect is ensured by heat exchange between circulating air, spray water and circulating water. Because it is a closed cycle, it can ensure that the water quality is not polluted, which well protects the efficient operation of the main equipment and increases its service life. When the outside temperature is low, the spray water system can be stopped to save water. In recent years, closed cooling towers have been widely used in industries such as steel metallurgy, power electronics, mechanical processing, air conditioning systems, and biomedicine.

[0003] However, when the existing closed cooling tower is in use, the cooling water cannot be quickly cooled after being sprayed, resulting in poor cooling effect of the cooling water on the heat exchange coil when the cooling water is sprayed for the second time. At the same time, if it is operated in cold seasons, if the spraying water is turned on, the fog plume at the air outlet will be serious, affecting the surrounding environment, resulting in low reliability of use. Therefore, we propose a high-efficiency closed cooling tower. Summary of the invention

[0004] In view of the above problems existing in the existing high-efficiency closed cooling tower, the present utility model is proposed.

[0005] Therefore, the utility model aims to provide a high-efficiency closed cooling tower, which solves the problem that in the existing high-efficiency closed cooling tower, there may be agglomerated engineering plastics on the screen during the screening process, resulting in inability to fully screen, and it is also difficult to screen engineering plastics of different sizes, affecting the screening efficiency, and it is difficult to collect the engineering plastics after screening, requiring manual cleaning, which increases the burden on the staff, resulting in more and more larger engineering plastics piling up above the screen, which over time affects the efficiency of the entire screening.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A high-efficiency closed cooling tower comprises a cooling tower shell, an evaporative heat exchange tube bundle and a circulating water tank, wherein a mounting frame is fixedly installed on the top of the cooling tower shell, an axial flow fan is fixedly installed inside the mounting frame, an evaporative heat exchange tube bundle is fixedly installed inside the cooling tower shell, a circulating water tank is fixedly installed on the bottom of the cooling tower shell, fixing frames are fixedly installed on both side surfaces of the top of the cooling tower shell, cooling pipes are wound inside the two fixing frames, one end of the two cooling pipes extends into the cooling tower shell and is fixedly installed with a shunt pipe, a plurality of water spray pipes are evenly installed between the two shunt pipes, and a plurality of nozzles are fixedly installed at the bottom of the plurality of water spray pipes.

[0008] Preferably, a double-head water pump is fixedly installed inside the circulating water tank, circulating water pipes are fixedly installed on both sides of the double-head water pump, and the other ends of the two circulating water pipes are fixedly connected to the other ends of the two cooling pipes respectively.

[0009] Preferably, first air inlets are fixedly installed on both sides of the bottom of the cooling tower shell, second air inlets are fixedly installed on both sides of the two fixed frames, and air outlets are respectively provided at the junctions between the two fixed frames and the two sides of the cooling tower shell.

[0010] Preferably, a heat sink is fixedly mounted on the top of the cooling tower shell, and both sides of the heat sink are respectively located at the top of the two air outlets.

[0011] Preferably, a water injection pipe is fixedly installed on one side of the circulating water tank, and a switch valve is fixedly installed on the surface of the water injection pipe.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

Circulating water pipes 12 are fixedly installed on both sides of the double-head water pump 11. The other ends of the two circulating water pipes 12 are respectively fixedly connected to the other ends of two cooling pipes 7 to facilitate the circulation of cooling water.
