Model of film type deaerator model of film type deaerator model of film type deaerator principle:

Film type deaerator and spray filler type, water type and other types of thermal deaerator in performance in the presence of the fundamentally different, the key lies in the spray structure caused by the steam heat and mass transfer, condensation water and supplement of water into the deaeration head rotary membrane for water chamber, at a pressure of 0.2MPa from a rotating membrane tube holes inclined jet to the inner wall, forming jet, because the inner holes filled with rising heating steam, water in the jet motion in a heated steam suction roll in ( proved by test that the jet motion with entrainment ), in a very short time very small strokes produce violent hybrid heating effect, the water temperature is greatly improved, and the rotation of the water along the rotating membrane tube wall of the inner hole from up to down to form a layer of backspin, paper thin water film rotary membrane skirt skirt, with sufficient heat exchange heating steam and water, heat and mass transfer effect of suboptimal temperature, oxygen saturation temperature is. Isolated, due to rotating flow close to the inner tube wall is rotated down, in a rotating membrane tube of steam and gas channel is formed in the middle, there is no gas flow zone, due to random diffusion of oxygen within the inner bore, escaping oxygen and non-condensable gas is rapidly discharged, as the only on The steam rising from the exhaust pipe exhaust to the atmosphere (Vintage deaerator is heating water isolated oxygen, but oxygen greater proportion than heating steam, oxygen was dirty water into the water tank, is caused by the deaerator effect difference of a reason ).

The rotary membrane deaerator water and coarse by drain pipe introducing hydrophobic here are mixed and the two distribution, homogeneous rain shape to attached to the lower liquid steam online, and deeply deoxidize before flowing into the water tank. The water in the water tank the oxygen content is lower than the ministerial standard.

Because the film type deaerator in work so that the water is always in a turbulent state, and has enough heat exchange surface area, and good heat transfer effect, exhaust steam amount is small (i.e. the energy loss is small, economic benefits is also considerable ), good deoxidizing effect, produces a rich volume overload ( the deaerator usually can exceed the rated output of50%) or low temperature the underwater operation.
