Description

Cooling Tower with Muffler

technical field

The invention relates to the technical field of cooling towers, in particular to a cooling tower with a muffler.

Background technique

The noise of the cooling tower is generated by the large-scale impact of the falling water in the tower and the water in the pool. The noise of the cooling tower is generated on the water surface of the falling water area and spreads around through the air inlet. Fan noise pollution is divided into mechanical noise and aerodynamic noise according to the mechanism of its generation. Mechanical noise is due to the frictional force, impact force or unbalanced force between the components when the mechanical equipment is running, which causes the mechanical components and the shell to vibrate and radiate noise.

With the improvement of urban residents' requirements for the quality of life, the continuous improvement of life, people's requirements for the quality of the living environment are getting higher and higher, and the noise pollution of cooling towers has gradually attracted people's attention, which has seriously affected people's normal life.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Please refer to FIGS. 1 to 4 at the same time, a cooling tower with a muffler includes a cooling tower 1, a packing channel 2 is arranged inside the cooling tower 1, and a radiator 3 is fixedly installed above the inside of the cooling tower 1, which belongs to the prior art. The commonly used structure in the cooling tower 1, the air inlet muffler 4 is fixed at the position of the air inlet on both sides of the cooling tower 1, which has a good noise reduction effect at the position of the air inlet 4, and the outer walls on both sides of the top of the cooling tower 1 are fixed. There is a fixed cylinder 7, and a lifting rod 8 is inserted into the top of the fixed cylinder 7, a threaded hole is opened on the outer wall of one side of the fixed cylinder 7, and a positioning bolt 9 is threadedly connected to the inner part of the threaded hole, and the positioning bolt 9 can be loosened. Let the lifting rod 8 lift up and down inside the fixed cylinder 7, the outer wall of the top of the two lifting rods 8 is fixedly installed with the outlet muffler 10, and the movable setting of the lifting rod 7 is convenient for the adjustment of the position of the outlet muffler 10 to achieve the best For the effect of noise reduction, the outer wall of the top of the air outlet muffler 10 is provided with through holes distributed at equal distances, and the inside of the through holes is provided with a muffler rod 11. The air outlet muffler 10 is located directly above the air outlet. The unique structure of the muffler rod 11 , greatly improving the muffler performance of the outlet muffler 10 .

Further, fixed lugs 5 are welded on the outer walls of the top and bottom of the air inlet muffler 4, and the fixed ear seat 5 forms a fixed connection with the outer wall of the cooling tower 1 through the butterfly screws 6, which is convenient for the installation of the air inlet muffler 4. And disassembly, to bring convenience to people.

Further, rubber gaskets are glued around the outer wall of one side of the air inlet muffler 4, and the rubber gaskets are in contact with the outer wall of the cooling tower 1. The structure of close contact effectively reduces the noise generated by mechanical vibration and reduces noise reduction. Effect.

Further, the muffler rod 11 includes an outer cavity 12 formed by a central hole on the air outlet muffler 10 , the interior of the outer cavity 12 is filled with sound-absorbing cotton 15 , and a center hole 14 is left on the centerline of the sound-absorbing cotton 15 .
