Embodiment Construction

[0011] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0012] Such as figure 1 As shown, an improved closed cooling tower of the present invention includes a tower body 1, an air inlet 2 and an air outlet 3. The air inlet 2 is provided in the lower part of the tower body 1, and the air inlet 2 is composed of an air inlet grille, and the air outlet 3 is set on the top of the tower 1, the air outlet 3 is provided with a protective cover 18, the air outlet 2 is provided with a load-bearing frame 4, the load-bearing frame 4 is fixed with a fan 5, and the tower 1 below the fan 5 is provided with a water collector 6. There is a spraying water distribution system under the water collector 6. The spraying water distribution system includes a nozzle 7 and a plurality of double nozzles 8 arranged under the nozzle 7, and an evaporation coil 9 is provided under the spraying water distribution system. , The evaporation coil 9...

Abstract

The invention discloses an improved closed cooling tower. The tower comprises a tower body, an air inlet and an air outlet, the air inlet is arranged at the lower portion of the tower body, the air inlet is formed by air inlet gratings, a bearing frame is arranged in the air outlet, a fan is fixed on the bearing frame, a water collecting device is arranged in the tower body below the fan, a water spray and distribution system is arranged below the water collecting device, the water spray and distribution system comprises a spray tube and a plurality of double-spray heads arranged below the spray tube, an evaporative coiler is arranged below the water spray and distribution system, the evaporative coiler is placed on a shelf, the shelf is fixed at the lower portion of the tower body, a water collecting tank is arranged at the bottom of the tower body, a filter screen is arranged over the water collecting tank, a water inlet is arranged at one side of the water collecting tank, and the water inlet is communicated with the spray tube through a water tube. According to the invention, the air inlet is formed by the air inlet gratings, so the air entrance is uniform; and the double-spray-head structure in the water spray and distribution system causes sufficient and uniform water spray, so sprayed water fully exchanges heat with the evaporative coiler and also fully exchanges heat with air, thereby the heat rejection amount is substantially increased.

Description

Technical field [0001] The invention relates to a cooling tower, in particular to an improved closed cooling tower. It is mainly used in various cooling systems such as metallurgy and casting, and belongs to the technical field of refrigeration devices. Background technique [0002] The existing cooling towers are all cooled by open water. The circulating cooling water is pumped to the filling of the cooling tower by the residual pressure of the circulating water pump, and then the water passing through the filling is cooled by a fan, enters the bottom of the tower, and then pumped to the cooling system by the water pump Inside. However, the biggest disadvantage of this cooling method is that the circulating water is easily polluted, causing scaling of the pipes and cooling system, and reducing the cooling effect. Therefore, it is necessary to provide a new technical solution to solve the above-mentioned problems. Summary of the invention [0003] The purpose of the present inv...
