Summary of the invention
The present invention is directed to the deficiencies in the prior art, providing one can repeatedly deoxygenation, greatly improves oxygen removal efficiency and deoxidize rate, and structure is simple, is convenient to the deoxygenation head of industrial applications.
For realizing the object of the invention, provide following technical scheme: a kind of deoxygenation head, comprise cylindrical shell, cylinder top venting port, the water outlet of cylindrical shell bottom, water outlet arranges joint flange, it is characterized in that in cylindrical shell, comprising the rotary film scavenge oxygen layer of arranging successively from top to bottom, first vapor film, filtering layer and the second vapor film, rotary film scavenge oxygen layer comprises and revolves film group hydroecium, arrange and the some intervals of revolving in film group hydroecium erect straight arranged rotation membrane pipe and arrange with on barrel with the hydrophobic water-in revolving film group hydroecium and be communicated with, de-mineralized water import, condensed water import, described hydrophobic water-in, de-mineralized water import, condensed water import all with revolve film group hydroecium barrel and be tangentially connected, hydrophobic water-in, de-mineralized water import, condensed water import is intervally arranged up and down in the shape of a spiral around the cylindrical shell center of circle, rotation membrane pipe offers permeable hole.
As preferably, hydrophobic water-in, de-mineralized water import, condensed water import is all downward-sloping forms 30 ~ 60 degree of angles with horizontal direction.Through Novel rotary film device in the shape of a spiral by certain design angle Guide spray, form water membrane skirt, and take over the heating steam of introducing with a heating steam and carry out revolving sufficient heat exchange in film device, form an effective deoxygenation.
As preferably, the first vapor film comprises the steam reliever of steam-pipe and steam-pipe end, and steam reliever comprises cylindrical shell and is evenly opened in the bar hole on cylindrical shell barrel around the center of circle.By distributing, ensure that steam more uniformly rises.
As preferably, filtering layer is made up of Pall ring filler.This kind of packing specific area is large, and turndown ratio is large, and separation efficiency is high, and energy consumption is low.Feedwater here fully contacts with secondary steam, is heated to temperature of saturation and carries out deep deoxygenization.
As preferably, the second vapor film comprises inlet pipe and is connected with the ring-type steam-distributing pipe of cylinder inboard wall with inlet pipe, and ring-type steam-distributing pipe surface uniform offers aperture.Best revolving can be kept to penetrate film skirt, and namely ensure that maximum gas liquid interfacial area, mass-and heat-transfer function is best, can remove to the 90%-95% of water oxygen level through this part deoxygenation.
Beneficial effect of the present invention: structure of the present invention is simple, carries out twice deoxygenation, substantially increase oxygen removal efficiency by rotary film scavenge oxygen layer and filtering layer, adapts to industrial applications.1, oxygen removal efficiency is high can reach more than 95%.
2, stable, shockproof.When sudden load change 25%, moisturizing sudden change 10%, during water temperature drop, deoxygenator does not still shake, also without vaporization situation.
3, conformability is good, and require outside the advantage such as not harsh to water quality, water temperature, and can run within the scope of 30%-110%, the deoxygenator of especially thermal power plant unit and sliding pressure operation more demonstrates its high-performance.
4, displacement is less than 0.1% of the entrance water yield, does not need separately to add vent condenser, than other type thermal deaerator is few consuming energy 1/3 with exerting oneself, optimizing equipment, reducing hear rate.

Embodiment
Embodiment 1: a kind of deoxygenation head, comprise cylindrical shell 1, cylindrical shell 1 top venting port 2, the water outlet 3 of cylindrical shell 1 bottom, water outlet 3 arranges joint flange 4, the rotary film scavenge oxygen layer 5 of arranging successively is from top to bottom comprised in cylindrical shell 1, first vapor film 6, filtering layer 7 and the second vapor film 8, rotary film scavenge oxygen layer 5 comprises and revolves film group hydroecium 5.1, arrange and 3 intervals of revolving in film group hydroecium 5.1 erect straight arranged rotation membrane pipe 5.2 and be arranged on barrel with the hydrophobic water-in 5.3 revolving film group hydroecium 5.1 and be communicated with, de-mineralized water import 5.4, condensed water import 5.5, described hydrophobic water-in 5.3, de-mineralized water import 5.4, condensed water import 5.5 all with revolve film group hydroecium 5.1 barrel and be tangentially connected, hydrophobic water-in, de-mineralized water import, condensed water import is intervally arranged up and down in the shape of a spiral around the cylindrical shell center of circle, rotation membrane pipe 5.2 offers permeable hole.First vapor film 6 comprises the steam reliever 6.2 of steam-pipe 6.1 and steam-pipe 6.1 end, and steam reliever 6.2 comprises cylindrical shell and is evenly opened in the bar hole 6.2.1 on cylindrical shell barrel around the center of circle.Filtering layer 7 is made up of Pall ring filler 7.1.Second vapor film 8 comprises inlet pipe 8.1 and is connected with the ring-type steam-distributing pipe 8.2 of cylindrical shell 1 inwall with inlet pipe 8.1, and ring-type steam-distributing pipe 8.2 surface uniform offers aperture.Revolve in film group hydroecium 5.1 and be provided with 2 airways 5.6.
Principle of work:
First condensed water and make up water enter deoxygenation head inward turning film device group hydroecium, from the little hole deviation churning inward hole of rotation membrane pipe under certain pressure reduction, form jet, because endoporus is filled with the heating steam of rising, a large amount of heating steam is just inhaled and is involved in by water in jet motion; The stroke that very short time is very little produces violent Hybrid Heating effect, water temperature increases substantially, and the water rotated continues backspin along film pipe orifice wall, form the water membrane skirt of one deck rolling, (critical Reynolds number of water when rotational flow declines, and a lot of generation is turbulent rolls), now the heat transfer water mass transfer effect of turbulent state is the most desirable, and water temperature reaches capacity temperature.Namely oxygen be separated, because oxygen cannot arbitrarily spread in endoporus, can only with rise steam from steam discharge pipe discharged to air.Carry out secondary distribution through the feedwater of the thick deoxygenation of skinning section and the hydrophobic mixing here of being introduced by drain pipe, fall on the liquid-steam web installed under it in shape of evenly drenching with rain, more just flow into water tank after carrying out deep deoxygenization.Water oxygen level in water tank is high pressure 3-5 μ ɡ/L, and low pressure is less than 10 μ ɡ/L well below ministerial standard (ministerial standard high pressure 7 ц ɡ/L, low pressure 15 ц ɡ/L).
Because rotating-film deaerator makes water be in turbulent state all the time at work, and have enough large heat transfer sheet area, so heat and mass effect is better, run under the affluence amount that displacement less (namely the little economic benefit brought of energy loss is also considerable) deaerating effect produces well can make deoxygenator overload operation (usually can surpass 50% of nominal output) or the full moisturizing of low water temperature.
With comparing of common deoxygenation head:
