Abstract
The utility model discloses a direct air-cooling system with a diversion muffling device. According to the direct air-cooling system, the technical problem that the surrounding environment is seriously polluted by noise generated by a traditional air-cooling fan is solved. The direct air-cooling system with the diversion muffling device comprises a cooling triangle (1), wherein an air-cooling fan (2) is arranged in the cooling triangle (1); an air guide duct support steel frame (5) is arranged below the air-cooling fan (2); an air guide duct (3) is arranged on the air guide duct support steel frame (5); the air-cooling fan (2) is arranged in the air guide duct (3); a grid air inlet channel (4) of which the horizontal cross section is rectangular and is positioned in the vertical direction is arranged in the air guide duct support steel frame (5); and a muffling panel (6) is arranged on the inner side wall of the grid air inlet channel (4). According to the direct air-cooling system disclosed by the utility model, noise generated by the air-cooling fan is weakened; the propagation of the noise generated by the air-cooling fan is changed downwards in a directive way; and noise pollution can be greatly reduced by paving cobblestones on the ground, afforesting and the like.
Description
Technical field
The utility model relates to a kind of direct air cooling system, and particularly a kind of thermal power plant can weaken noise significantly and improve the direct air cooling system of noise transmission Directivity.
Background technique
The equipment that the thermal power plant direct air cooling system produces noise mainly is blower fan group, motor and gear-box.The noise that air cooling blower fan produces is a low-frequency noise, and is slower with the propagation decay.At present, all about 35 meters, because point source of sound is high more, sound will pass far more the podium level of conventional direct air cooling system, and the noise that blower fan is produced has produced serious pollution to surrounding environment.
Summary of the invention
The utility model provides a kind of direct air cooling system that has the water conservancy diversion silencer, has solved the technical problem of the noise of existing air cooling blower fan generation to the severe contamination of surrounding environment generation.
The utility model overcomes the above problems through following scheme:
A kind of direct air cooling system that has the water conservancy diversion silencer; Comprise the cooling triangle, the air cooling blower fan that in the cooling triangle, is provided with is provided with the air conducting tube supporting steel frame below air cooling blower fan; The air conducting tube supporting steel frame is provided with air conducting tube; Air cooling blower fan is arranged in the air conducting tube, and in the air conducting tube supporting steel frame, being provided with the level cross-sectionn is the rectangular grid air intake passage of Vertical direction up and down, and the madial wall of grid air intake passage is provided with acoustical panel.
The level cross-sectionn of each the grid passage that in the air conducting tube supporting steel frame, is provided with is all identical.
The utility model has weakened the noise of direct air cooling system significantly, can improve direct air cooling system propagation of noise Directivity simultaneously, and the noise reduction of floor pavement cobble and greening is strengthened.
