Fig. 3 is the utility model one embodiment schematic diagram.
Wherein: 1 tower body, 2 air ducts, 3 blower fans, 4 water inlet pipes, 5 hydraulic turbines, 6 water-distributing devices, 7 ponds, 8 packing layers, 9 air inlets.
The specific embodiment
Fig. 2 is structural representation of the present utility model, as shown in Figure 2, the utility model provides a kind of mechanical-draft cooling tower system, comprise tower body 1, air duct 2, blower fan 3, water inlet pipe 4 and the hydraulic turbine 5, described air duct 2 is arranged on the tower body 1, is connected with tower body 1, described blower fan 3 is arranged in the air duct 2, described water inlet pipe 4 is positioned at tower body 1 top, and the described hydraulic turbine 5 is installed on the water inlet pipe 4, is connected with blower fan 3 axles; Be provided with water-distributing device 6 in the described tower body 1, described water-distributing device 6 is positioned at the hydraulic turbine 5 belows, is connected with the tail water pipeline (not shown) of the hydraulic turbine 5; Described tower body 1 bottom is connected with pond 7; Described water-distributing device 6 belows are provided with packing layer 8; The hydraulic pressure of described water inlet pipe 4 and the hydraulic turbine 5 junctions is greater than 0.08MPa; Described tower body 1 bottom is provided with air inlet 9.
Cooling tower is the contact that utilizes water and air, by leave a kind of equipment of used heat of industry and air conditioner refrigerating generation of evaporation.Generally be divided into cooling stack by its draft type, mechanical-draft cooling tower, mixed ventilation cooling tower.Present technique is applicable to mechanical-draft cooling tower, and it is to utilize the hydro powered blower fan of cooling tower to substitute traditional driven by power blower fan of cooling tower, saves the energy.Use present technique must guarantee that tower sprays total pipe pressure greater than 0.08Mpa on the cooling tower backwater.By installing the hydraulic turbine additional at cat head, the pressure that can effectively utilize the design margin of cat head to produce reduces energy dissipation, and adopt the hydraulic turbine to drive blower fan, saved traditional employing electric power and driven the required electric power energy of blower fan, for enterprise provides cost savings, increased economic efficiency.
