Description
Technical field
The utility model relates to deoxygenation technology field, particularly relates to a kind of built-in deaerator.
Background technology
Rotating-film deaerator is the substitute products of spray-filling type deaerator, a kind of latest model thermal type deoxygenation of production
Device, membrane deaerator principle be moisturizing through rotating-film tube in the shape of a spiral by certain angle ejection with add vapours and carry out heat exchange and remove
Oxygen, feedwater is heated to the saturation temperature under corresponding oxygen-eliminating device operating pressure, removes oxygen and other gas being dissolved in feedwater, prevent
With reduction boiler feed pipe, economizer and the corrosion of other auxiliary device.Electricity Department GB1576-2001 " power station pressure type deoxygenation
Device safety and technical supervision code ".
Condense water and supplementary water initially enters deoxygenation head inward turning film device group hydroecium, from membrane tube under certain differential pressure of water level
Little hole deviation churning inward hole, forms jet, and owing to endoporus is filled with the vapours that adds of rising, water just will be a large amount of in jet moves
The vapours that adds inhale and involve in (test prove jet move there is Involving velocity)；The stroke that very short time is the least produces play
Strong Hybrid Heating effect, water temperature increases substantially, and the water rotated continues backspin along membrane tube inner hole wall, forms one layer of rolling
Water membrane skirt, (water critical Reynolds number when rotational flow decline a lot of produce turbulent flow rolling), the now water of turbulent condition
Heat and mass effect is the most preferable, and water temperature reaches saturation temperature.Oxygen is i.e. separated, because oxygen cannot arbitrarily expand in endoporus
Dissipating, the steam that can only rise (though old-fashioned oxygen-eliminating device heated water, has isolated oxygen but oxygen ratio is great from gland steam exhauster row to air
In adding vapours, part oxygen is brought into water tank by dirty water again, is also a kind of reason causing deaerating effect difference).Through skinning section
The feedwater of thick deoxygenation and the hydrophobic mixing here introduced by drain pipe carry out secondary distribution, fall installing to it in shape of uniformly drenching with rain
Under liquid-steam web on, then carry out just flowing into after deep deoxygenization water tank.Water oxygen content in water tank is high pressure 0-7 ц/L, and low pressure is little
Operation standard promulgated by the ministries or commissions of the Central Government is reached in 15 ц/L.
Existing oxygen-eliminating device internal underpressure size is difficult to condition, and poor to the crushing effect of current, heating-up temperature simultaneously
It is difficult to regulation, causes deaerating effect poor, and oxygen-eliminating device madial wall is susceptible to corrosion, affects the service life of oxygen-eliminating device.
