Product Description

I. Overview.
   Our new high efficiency rotary film deaerator is a new structure of deaerator which has been researched and promoted in recent years. Its design is mainly to change the original jet type into rotary jet film type, is a set of rotary film and bubble boiling condensation as one of the high efficiency new water film type deaerator, with high efficiency of oxygen removal, uniform heat exchange, small steam consumption, stable operation, good adaptability, the water quality, water temperature requirements are not harsh, etc., and can exceed the force of about 20 ~ 50% operation.

II. Principle.
    The heat transfer, mass transfer of the new high-efficiency rotary film deaerator is different from the existing drenching disc type, rotary film type and atomization type, mainly the three heat transfer methods of jet, rotary film and suspended bubble Buddha are shrunk into one heat transfer, mass transfer method, which has high efficiency. The new rotary film tube has a great resolving capacity and causes the liquid film to rotate strongly along the wall of the tube to absorb a large amount of steam, enhancing the heat transfer and mass transfer functions, changing the phase bubble boiling to suspended bubble boiling, improving the flood point (splash) when the steam flow rate is high in each layer and being able to maintain the steam (gas) channel; shrinking the three independent heat and mass transfer devices into one, which is completed within a single unit of components.
    Because of its high efficiency and certain special features, it breaks through the technical performance of existing deaerators. This deaerator is an improved version of the rotary film type deaerator.

 
 

III.Structure 
The structure of the deaerator is shown in Figure  It is composed of
(1) shell
(2) vapour-water separator
(3) new rotary film starter
(4) spray grille
(5) conventional liquid vapour network
(6) water tank.
The whole set of deaerators is illustrated in Fig.

 1:Shell: is made of cylinder body and stamping oval head welding.
   
 2:vapor separator: this device replaces the original old-style deaerator within the straw hat cone structure design, so that the deaerator eliminates the discharge of steam with water phenomenon so that the heat loss of the discharge of steam is reduced to 0.5 ‰ or less.
 

 3:New type rotary film starter:
consists of water chamber, steam chamber, film starter pipe, condensate receiver, supplementary water pipe, hydrophobic receiver and once into the steam receiver. The new rotary film starter has a water film guiding device inside the rotary film tube, which can strongly lower the film even when running at low load and maintain a good rotary film skirt. Condensate, chemical make-up water, through the starting film tube is spiral according to a certain angle spray, the formation of water film skirt, and by the water tank through the liquid steam network, the water grate rising heating steam contact is heated to close to the deaerator working pressure under the saturation temperature (i.e. below the saturation temperature 2-3 ºC) and coarse oxygen removal. Generally by this start film section can remove the oxygen content of the feed water about 90-95%.


  4:Shower grate:
It is made up of several layers of staggered angular steel parts, and the feed water of the coarse oxygen removal by the starting film section and the secondary distribution by the high plus hydrophobic mixing here, falls to the liquid vapour net installed under it in the form of uniform shower.

 5: gauge packing liquid vapour network:
    is composed of many open shape size of the same unit of SW-type mesh corrugated packing, composed of a cylinder, the gauge packing to maintain the advantages of screen corrugated packing and orifice plate corrugated packing, but also a large surface area, small pressure drop, operating flexibility, high separation efficiency, low energy consumption, never fall off and other characteristics. Feed water in full contact with the secondary steam here, heated to saturation temperature and when the depth of deoxygenation, low-pressure atmospheric deoxygenator below ≤ 10 PPb (national standard ≤ 15 PPb), high-pressure deoxygenator below ≤ 7 PPb.
  6:Water tank:
    In addition to the oxygen feed water gathered to the lower container of the oxygen removal head in the feed water tank, the oxygen removal water tank is equipped with a new scientific design of strong heat exchange reboiling device, the device has the advantages of strong heat exchange, quickly enhance the water temperature, more depth of oxygen removal, reduce the vibration of the tank, reduce noise, etc., improve the service life of the equipment, to ensure the safety and reliability of equipment operation.
