Embodiment Construction

[0016] Below in conjunction with accompanying drawing, patent of the present invention is described further.

[0017] figure 1 Schematic diagram of the structure of the environment-friendly and water-saving cooling tower provided by the present invention when mechanical ventilation is used. The cooling tower includes a tower body 17, a water collector 10, a water distributor 9, a packing layer 7, a water storage tank 5 arranged in the tower body, an air inlet louver 6 arranged on the side wall of the tower body below the packing layer, a circulating water inlet Water pipe 1, circulating water return pipe 3 and corresponding valves. The air cooler louvers 12 are arranged symmetrically on the side wall of the cooling tower, and the air cooler 13 is arranged close to the air inlet louvers inside the tower body. The air cooler adopts plate-fin-fin tube type, Spiral finned tube type or nested finned tube type structure, the finned tubes are round tubes, elliptical tubes or porous...

Abstract

The invention discloses an environment-friendly water-saving cooling tower, which is a cooler used in cycle water temperature decrease. Wherein, the side wall of tower is symmetry distributed with wind inlet shutters of air cooler; the inner side that near to the shutters is distributed with an air cooler; the water distributing tube at the inner side of air cooler is through to the water inlet tube of cycle water, while the water outlet tube of air cooler is through to the water distributor; the lower water tank of air cooler via the branch tube is through to the reflux tube of recycle water; the air cooler is above the water collector; the water distributor is between two air coolers. The invention uses air cooler to pre-cool the cycle water, to reduce the load of stuff section, the steam amount and the water consumption. And since the air is dry and heat via the air cooler, it can reduce the humidity of hot and humid air that exchanged heat with stuff layer, to reduce the fog at the tower.

Description

technical field [0001] The invention relates to a cooling tower for circulating water cooling, which can be widely used in thermal power generation, petroleum, chemical industry and other [0002] technology field. Background technique [0003] The function of the cooling tower is to exchange heat between the circulating water carrying waste heat and the air in the tower, transfer the heat of the water to the air and disperse it into the atmosphere, and cool down the circulating water. Cooling towers are divided into wet cooling towers and dry cooling towers according to the contact mode of circulating water and air. [0004] In the wet cooling tower, the circulating water spread on the surface of the filler is in direct contact with the air, and the heat of the water is transferred to the air through contact heat transfer and evaporative heat dissipation. The heat exchange efficiency of the wet tower is high, and the limit temperature at which the water is cooled is the w...
