Abstract
The utility model discloses a kinetic energy recycling wind cone of a cooling tower, comprising an inlet contraction section, a fan working section, a divergent section and an outlet retraction section. The inlet contraction section is arranged on the inlet of the wind cone while the outlet retraction section is arranged on the outlet thereof; the fan working section and the divergent section are orderly arranged between the inlet contraction section and the outlet retraction section. The wind cone has obvious advantages of low material consumption, convenient and simple assembly and obvious kinetic energy recycling. The speed of air is gradually reduced after passing through the fan working section and a diffusion section, and the wind speed can be more uniform after passing through the outlet retraction section to average the outlet air flow speed, for the more even the outlet air flow speed is, under equal area, the more obvious the kinetic energy recycling is. The design of the reaction section can lead the air flow to be more even and enhance the wind cone strength. As FRP material is utilized, the wind cone is durable. The recycling wind cone can be applied to various mechanical ventilation cooling towers.
Description
Technical field
The utility model relates to a kind of cooling tower air duct, specifically a kind of reduction cooling tower air outlet wind speed, and recovery section air outlet gas kinetic energy is saved the cooling tower air duct of blower fan power consumption.
Background technology
The air duct that cooling tower is extensively practical mostly is flaring type or straight air duct at present, and there is following shortcoming in this air duct: the manufacturing cost height, and consumptive material is many, inconvenience is installed, analyzes simulated test through the convection cell molded lines, adopt flow field homogenizing theory, improve and made a kind of novel cooling tower air duct.
The utility model content
Technical problem to be solved in the utility model provides cooling tower recover kinetic energy air duct at the existing in prior technology defective, solve the above-mentioned defective of prior art, main purpose is to reduce the air duct height under the equivalent diameter, reduces the blower fan power consumption, save and use material, make installation light.
The technical scheme that its technical problem that solves the utility model adopts is: cooling tower recover kinetic energy air duct, its structure comprise inlet contraction section, blower fan active section, divergent segment, outlet retraction section; Described air duct porch is the inlet contraction section, and the exit is outlet retraction section, also is provided with blower fan active section, divergent segment successively between described inlet contraction section and the outlet retraction section.
Described wall vertical section by inlet contraction section, blower fan active section, divergent segment, the outlet retraction section air duct of forming is streamlined level and smooth wave-like.
Cooling tower recover kinetic energy air duct of the present utility model, as follows with respect to its concrete beneficial effect performance of prior art:
The utility model great advantage is to save material, assembles lightly, and recover kinetic energy is obvious.Air is through after the blower fan active section, and through diffuser, speed reduces gradually, but again through after the outlet retraction section, wind speed is homogenising more, makes exit flow speed be tending towards on average again, in that the mean kinetic energy recovery is obvious more more with homalographic downstream speed.The advantage design of retraction section promptly can uniform air flow, can strengthen air duct intensity again, and material selects for use the FRP material to make.Can be durable in use, can be widely used in various motor-driven aerating and cooling towers.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Figure is a cooling tower recover kinetic energy air duct section type line structure schematic diagram of the present utility model.
Wherein: 1, inlet contraction section; 2, blower fan active section; 3, divergent segment; 4, outlet retraction section.
The specific embodiment
Shown in figure, cooling tower recover kinetic energy air duct, its structure comprises inlet contraction section 1, blower fan active section 2, divergent segment 3, outlet retraction section 4; Described air duct porch is the inlet contraction section, and the exit is outlet retraction section, also is provided with blower fan active section, divergent segment successively between described inlet contraction section and the outlet retraction section.Described wall vertical section by inlet contraction section, blower fan active section, divergent segment, the outlet retraction section air duct of forming is streamlined level and smooth wave-like.
The inlet contraction section is that gas flow smooth is compiled, and enters the blower fan active section in the mode of seamlessly transitting, and, makes gas have certain energy and enters divergent segment the gas acting through the fan blade rotation.Along with area increases, wind speed reduces, and kinetic energy reduces gradually, through the outlet exhausting section, makes air-flow more be tending towards even in muzzle velocity again.When wind speed 8m/s, dynamic pressure reduces 11.08Pa through this form recover kinetic energy air duct of testing authentication, and recover kinetic energy is obvious, and energy-saving effect is remarkable.
This air duct mostly is that sheet is combined and spliced to form.Highly low, easy to assembly, be widely used in various induced cooling towers.
