Described gas-liquid separation device comprises ring diversion plate and porous barrier, ring diversion plate is located at air-water mixture inlet, the ring diversion plate top is provided with E shape turbulent baffle, E shape turbulent baffle intersects with ring diversion plate and is oppositely arranged, make and also carried out elementary gas-liquid separation when steam is diversed goes into silencing apparatus, porous barrier is arranged on E shape turbulent baffle top, be the gas-liquid separation layer between the porous barrier, steam has carried out the multi-stage gas-liquid separation again when flowing through between the multi-layer porous dividing plate, thereby has strengthened gas-liquid separation effect greatly.
The resistive sound absorber of described annular comprises and a plurality ofly with one heart and the annular absorbing screen that increases successively to outer radius from the lining leaves steam channel between the adjacent annular absorbing screen that steam flow carries out the secondary sound absorption when the resistive sound absorber of annular.
Described drain opening top is provided with vortex eliminator, can prevent the vibrations that silencing apparatus causes because of the untimely generation eddy current of draining.
Described cylinder inboard wall is provided with the erosion control brush board, has avoided the direct corrosion of steam to silencer internal wall.
Described cylindrical shell top is provided with rainhat, prevents from because of weather vapor discharge to be impacted.
Working procedure and principle:
The mixture of steam and water carries out first air-water separation from n1, the tangential access arrangement of n2 mouth by ring diversion plate, E shape turbulent baffle, and steam upwards flows, liquid flows to tenesmus; In steam made progress process of flowing, the liquid that remains in the gas carried out secondary separation by gas-liquid separation device, and residual liquid weighs down the flow device bottom once more, and gas then continues upwards to pass through barrel annular sound absorption circle, weakens the gas sound pressure.Gas continuation rising through first sound absorption absorbs sound by the resistive sound absorber of final multi-layer annular, reduces the gas acoustic pressure, and through the gas device for transferring after the sound absorption, liquid is then discharged by the n3 mouth.Finally reach the purpose of noise elimination, and reached the effect of gas-liquid separation.
In addition, whole steam silencing apparatus can change the position of drain opening and rainhat as required when settling, and carries out level or vertical the installation, settles easy to use.
The beneficial effect that the utility model had is: a kind of steam silencing apparatus is provided, by annular resistive sound absorber is set, the noise reduction of silencing apparatus is significantly strengthened; By E type turbulent baffle and porous barrier are set, the gas in the steam is effectively separated with liquid, reduced the corrosion of high-temperature vapour to equipment, prolonged the working life of silencing equipment; By vortex eliminator being set, can prevent the vibrations that silencing apparatus causes because of the untimely generation eddy current of draining on drain opening top; Whole silencing apparatus takes up room little and can carry out level as required or vertical the installation, settles easy to use.
