Background technology
Air cooling condensing technology is widely used in power plant, air cooling tubes condenser receives the vapours from boiler, and cold air is flow through air cooling tubes condenser by blower fan, thus makes the steam-condensation flowing through air cooling tubes condenser, condensed water after condensation, through condensate pipe water conservancy diversion, returns to the feed water system of boiler.
Air cooling tubes condenser comprises steam-distributing pipe, finned-tube bundle, solidifying water collects header and the condensate pipe that water collects header is coagulated in connection.
Vapours from steam turbine enters air cooling tubes condenser, through too much group finned-tube bundle heat radiation by steam-distributing pipe level, thus make most steam-condensation be condensed water, flow through horizontally disposed condensate water collecting header, condensate pipe is connected with condensate water collecting header is vertical, flowed out gradually by the tube wall of condensate water collecting header along condensate pipe to make condensed water, in water supply system again in water conservancy diversion back boiler, recycle.
Prevent vibration and noise, condensed water needs to press close to the tube wall of condensate pipe slowly to flow out downwards, but in prior art, condensed water usually occurs stopping and cannot press close to the phenomenon of condensate pipe tube wall, and the generation of this phenomenon is mainly caused by following reason:
One, thinking that vibration occurs condensing water conduit is impact a large amount of energy of release by water column, and pipe-line system has the frequency of low-frequency oscillation simultaneously, and flexibility is too large, rigidity is too little, and consequent pipe stream resonance causes;
Two, condensing water conduit vertical paragraph difference is larger, be generally 30 ~ 45 meters, excessive drop makes to manage interior condensate water to be accelerated at dropping process medium velocity, produces localized low-pressure zone and makes condensate water that vaporization formation biphase gas and liquid flow occur, pipe-line system is impacted, produces vibration and noise simultaneously;
Three, when condensed water vertically flows into condensate pipe by condensate water collecting header, the reason such as flow velocity, flow also can cause current to depart from tube wall, occurs cutout phenomenon.
Because above-mentioned unavoidable cause causes condensed water to depart from the tube wall of condensate pipe, directly impact the bottom of condensate pipe.So, long-term condensed water impacts condensate pipe and causes vibrations and noise, easily causes the damage of condensate pipe, constrains the service life of condensate pipe.
In view of this, how design is optimized to condensate pipe, guarantees the tube wall water conservancy diversion of condensed water along condensate pipe, improve the flowing of condensed water, reduce vibration and the noise thereof of condensate pipe, effectively improve the service life of condensate pipe.
