Description
Technical field
The utility model relates to a kind of boiler feedwater treatment facility, particularly a kind of atomizing rotating-film deaerator.
Background technology
In boiler feedwater treatment process process, deoxygenation is unusual the key link.Oxygen is the main corrosive deposit of water supply system and boiler, the corrosion product iron oxide can enter in the system, the deposition or attached on boiler tube wall and the heating surface, form indissoluble and do not conduct heat, cause the hole oxygen corrosion of inner-walls of duct appearance point, resistance coefficient increases, and increases the unit irreversible loss, when serious booster can take place and burst accident.General thermal deaerator commonly used has spraying material filling type, trickle disc type, the adaptability that its operating condition changes is relatively poor, aborning because the variation of water inlet and initial steam pressure, when reducing, the intake pressure flow forms the water column shape, do not play nebulization, the surface area of water dwindles at double, and filler is a stainless steel substrates, belong to surface heat transfer and can not make the water uniform atomizing, and run duration is piled up by thermal vibration to produce water, vapour locking to influence deaerating effect easily and exerted oneself.Easily form spilling water when high load capacity, heat transfer condition is degenerated, do not reach deaerating effect, steam consumption also increases.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed that a kind of deaerating effect is good, characteristic is perfect, efficient energy-saving, can reach the rotating-film deaerator of deep deoxygenization requirement.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of rotating-film deaerator, comprise oxygen-removing tower and bottom water tank, the oxygen-removing tower top is provided with blast pipe, be provided with steam-water separator in the deoxygenation tower body from top to bottom, revolve the film device, height adds drain pipe, water drenching device, filler stratum reticulare and air chamber, steam-water separator and blast pipe join, be characterized in: add the erosion control atomizer is housed between the drain pipe revolving film device and height, described erosion control atomizer is made by the coiling of stainless steel flat filament net.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, the described film device that revolves comprises hydroecium, steam chest and rotation membrane pipe, the middle part of rotation membrane pipe is provided with dividing plate, the top of dividing plate is hydroecium, the bottom of dividing plate is a steam chest, hydroecium is provided with the condensate water adapter and supplementing water is taken over, steam chest is provided with an admission and takes over, the upper and lower of rotation membrane pipe all is provided with the hole of advancing of several helical pattern, its lead angle is 15 °～20 °, the hole of advancing on the described rotation membrane pipe is an inclined hole, and the angle between the radius of inclined hole center line and inside pipe wall joining is α, 67 °≤α＜72 °.
The technical problems to be solved in the utility model can also come to realize that further described water drenching device is made up of several layers of staggered dihedral steel by the following technical programs.The water process water drenching device that flows from top to bottom forms countless moisture films and fully contacts with the heating steam of reverse flow, increased the time of contact of carbonated drink, made water reach saturation temperature under the corresponding pressure, constantly seethed with excitement again, be convenient to residual gas and separate, reach the purpose of deep deoxygenization.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further the filler stratum reticulare is the band steel band by the space that interior dress high temperature elastic stainless steel flat filament net constitutes.Its surface area is big, increases the diffusion area of residual gas in the water, prolongs the time of staying of current, makes current be disperseed to be the moisture film shape through the filler stratum reticulare, fully contacts with steam to reach deep deoxygenization.The accumulation of heat filler itself is exactly the storage heater of indirect steam, feeds water and the storage heater sufficient heat exchange, has reached the purpose of deep deoxygenization.
The utility model rotating-film deaerator, be provided with steam-water separator in its oxygen-removing tower from top to bottom, revolve the film device, erosion control atomizer, height add drain pipe, water drenching device, filler stratum reticulare and air chamber, the erosion control atomizer makes and revolves the get off surface area of water of film device and increase, evenly carry out heat exchange with the steam that comes on the bottom, and can reach the effect of deoxygenation once more, and can buffered water, vapour is because the impulsive force that the temperature difference causes makes the steadily moving row of safety of oxygen-eliminating device.Compared with prior art, its deaerating effect is good, characteristic is perfect, efficient energy-saving, can reach the requirement of deep deoxygenization, to reach the value that goes up most of boiler feedwater water standard.Particularly improve at the enterprising line number item of the structure of revolving film device, erosion control atomizer, water drenching device and filler net, this oxygen-eliminating device can be used for modes such as level pressure, sliding pressure and moves, and is applicable to all kinds of power plant, steam power plant and Industrial Boiler.
