Background technique

The cooling tower is a product for cooling the central air-conditioning host or equipment used in various industrial places. Its refrigeration principle is to take away the heat in the water through the evaporation of water and heat conduction, thereby cooling the equipment.

The existing cooling towers are divided into open cooling towers and closed cooling towers according to the contact form of the medium and air, and the open cooling towers are further divided into cross-flow cooling towers, counter-flow cooling towers, spray cooling towers, etc.

Existing cross-flow cooling towers or counter-flow cooling towers usually use fillers to increase the contact area between water and air, so as to achieve the purpose of improving the cooling effect. The packing of the cross-flow cooling tower is located on both sides of the tower body, and the air and water cross flow horizontally; the packing of the counter-flow cooling tower is located in the middle of the tower body, and the air and water cross vertically. Both cooling towers have the problem of low space utilization.

A mixed-flow open-type cooling tower, including a cooling tower body composed of fillers, air ducts, panels, water tanks, water distribution pipes, escalators and water eliminators. The bottom of the cooling tower body is supported by outriggers. It is characterized in that: the The filler includes the cross-flow tower filler and the counter-flow tower filler arranged inside the cooling tower body. The cross-flow tower filler is set in correspondence with the air inlet on the left and right sides of the cooling tower body. In contrast, the counter-current tower packing is arranged on the upper part of the cross-flow tower packing, and the surrounding sides of the counter-current tower packing are respectively against the inner wall of the panel of the cooling tower body.

The cooling tower body is provided with an inspection space, the inspection space is located between the fillers of the cross-flow tower, and a water baffle is arranged in the inspection space;

An inspection door corresponding to the inspection space is arranged on the panel.

The water baffle is a V-shaped structure with the opening facing downwards.

The air inlet is located at the lower part of the side where it is located.

The packing of the countercurrent tower adopts oblique wave packing.

detailed description

The implementation of the present utility model is illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

As shown in Figures 1, 2, and 3: a mixed-flow open-type cooling tower, including a cooling tower body composed of fillers, air ducts 1, panels 3, water tanks 11, water distribution pipes 16, escalators 9 and water eliminators 15, cooling The bottom of the tower body is supported by outriggers 12, the side of the cooling tower body is sealed by panels 3, and air inlets 4 are reserved at the lower parts of the left and right sides of the cooling tower body. On the outside of the air outlet on the top of the cooling tower body, a reduction motor 14 is provided inside the air duct 1. The reduction motor 14 is connected to a motor 14. The water collector 15 is located at the lower part of the air outlet inside the cooling tower body, and the water distribution pipe 16 is located at the water collection The lower part of the device 15 and its end are connected to the water inlet 2, the bottom of the water distribution pipe 16 is provided with a number of evenly distributed nozzles 17, the water tank 11 is arranged at the bottom of the cooling tower body, and the water tank 11 is provided with an overflow port 5, a water supply port 6, and a sewage outlet 7 and the water outlet 8, and the escalator 9 is arranged on one side of the cooling tower body for inspection and maintenance;
