Description
Technical field
The invention belongs to a kind of cooling means and device of air cooling compressor, refer in particular to a kind of method and device that can improve air cooling compressor exhaust gas flow noise, belong to the cooling technology field.
Background technology
Known cooling tower often because the speed of cooling air is higher, and can produce certain pneumatic noise carrying out air when cooling, and the environment at scene is impacted.The method of general reduction air cooling compressor exhaust gas flow noise is to increase the diffusion chamber with same vertical axis on the vertical axis of cat head ventilating duct, or increases silencing apparatus in this diffusion chamber.The substantive characteristics of the method for this reduction exhaust gas flow noise is: the air-flow of discharging from ventilating duct outlet with the boundling diffusion way outside the ventilating duct vertical axis is discharged tower.The defective that this boundling diffusion axially goes out the existence of tower method is conspicuous: exhaust gas stream is kept the whole boundling type of flow, the flow velocity of exhaust gas stream is not significantly reduced, the path that arrives the air-flow free space from the noise focus of ventilating duct air outlet is very short, and noise intensity does not have enough chances to realize significantly decay.The existing boundling diffusion of continuing to use that is called as low noise or ultra-low noise axially goes out the air cooling compressor of tower method, although taked all noise countermeasures to reduce the exhaust gas flow noise, is difficult to obtain gratifying effect and progress always.Therefore, necessaryly existing air cooling compressor and boundling diffusion thereof are axially gone out the tower method improved.
Summary of the invention
The objective of the invention is to eliminate some deficiency in the reduction air cooling compressor exhaust gas flow noise method and technology that has air cooling compressor now, propose the method that the lower air cooling compressor of a kind of exhaust gas flow noise reduces noise.
Another object of the present invention is to propose a kind of device of realizing said method according to said method.
The technical solution used in the present invention is: take shunting diffusion radially to go out the tower method, cluster type exhaust gas stream is become distributing exhaust gas stream, air-flow is axially gone out tower become air-flow by a shunting diffusion zone and radially go out tower.Described shunting diffusion zone allows airflow diversion diffusion after the heat exchange of discharging from ventilating duct air outlet boundling, shunting diffusion air-flow is with parallel or in the same way in the type of flow of ventilating duct radial direction, discharge outside the tower through multidirectional bending passage more than, carry out the noise reduction of exhaust gas flow noise by the mode of multidirectional baffling.
