Background technology
Industrial Boiler is the equipment being carried out by water heating produces steam producing.If dissolved oxygen in oiler feed, the metallic corrosion contacted with water will be made, disadvantageous effect has been caused to the use of e-quipment and pipe.The oxygen often contained in natural water can reach 10 mg/litre, therefore contains a certain amount of oxygen in boiler supplementary feed.Therefore, feed water before entering boiler, first through deoxygenator, the Main Function of deoxygenator is exactly the oxygen in removing oiler feed.Existing deoxygenator, because Deaerator Structure design is unreasonable, causes steam well evenly not spread to upside, cause heating steam area when contacting with atomizing state feedwater large not, contact not all fully even, deaerating effect is bad, itself and complex structure, the space taken is too large.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of rotating-film deaerator, this apparatus structure is simple, reasonable in design, make heating steam and the atomizing state contact area that feeds water enough large, contact all fully even, thus ensure efficiently to feedwater deaeration, and the space taken is little.
To achieve these goals, the utility model adopts following technical measures: a kind of rotating-film deaerator, comprise water tank, water tank is connected with rotating-film deaerator oxygen-removing tower, skinning device is provided with successively from top to bottom in rotating-film deaerator oxygen-removing tower, trickle comb layer, packing layer and point vapour device, described diffuser comprises steam inlet pipe, steam inlet pipe one end is communicated with vapour source, the other end is connected with the sub-steam pipe vertically arranged, sub-steam pipe two ends are closed respectively by upper cover plate and lower cover, upper cover plate diameter is greater than sub-steam pipe external diameter, sub-steam pipe is provided with vertical kidney-shaped steam vent, described steam vent is uniformly distributed in sub-steam pipe, described sub-steam pipe is fixed in rotating-film deaerator oxygen-removing tower by support.
In technique scheme, described sub-steam pipe comprises inner sleeve and outer tube, and described outer tube diameter is the twice of inner sleeve diameter.
In technique scheme, the internal diameter of described outer tube is 1700-1800mm, and the internal diameter of described steam inlet pipe is 650-750mm.
In technique scheme, described trickle comb layer and skinning device spacing are 800-900mm, and the spacing of trickle comb layer and packing layer is 80-100mm.
In technique scheme, described packing layer is efficient regular wire packing Ω ring filler layer.
This rotating-film deaerator structure is simple, reasonable in design, make heating steam and atomizing state feed water contact area enough greatly, contact all fully even, thus ensure efficiently to feedwater deaeration, and the space taken is little.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As Fig. 1, 2, a kind of rotating-film deaerator shown in 3, comprise water tank 1, water tank 1 is connected with rotating-film deaerator oxygen-removing tower 2, skinning device 3 is provided with successively from top to bottom in rotating-film deaerator oxygen-removing tower 2, trickle comb layer 4, packing layer 5 and point vapour device 6, described point of vapour device 6 comprises steam inlet pipe 7, steam inlet pipe 7 one end is communicated with vapour source, the other end is connected with the sub-steam pipe 8 vertically arranged, sub-steam pipe 8 two ends are closed respectively by upper cover plate and lower cover, upper cover plate 13 diameter is greater than (slightly greatly) sub-steam pipe 8 external diameter, sub-steam pipe 8 is provided with vertical kidney-shaped steam vent 9, described steam vent 9 is uniformly distributed, described sub-steam pipe 8 is fixed in rotating-film deaerator oxygen-removing tower 2 by support 10.Steam inlet pipe 7 is axially connected with sub-steam pipe 8 radial direction, and namely steam inlet pipe 7 level, sub-steam pipe 8 are vertically arranged, and at the diameter increasing sub-steam pipe 8, can cut the height reducing point vapour device 6 while not reducing quantity of steam, can make the height reduction of whole equipment like this.Upper cover plate 13 diameter is slightly large, is to stop that water droplet is dripped in sub-steam pipe 8 by steam vent 9.
In technique scheme, described sub-steam pipe 8 comprises inner sleeve 11 and outer tube 12, and described outer tube 12 diameter is the twice of inner sleeve 11 diameter.If the diameter of sub-steam pipe 8 is excessive, then its internal space is excessive, and its environment for use air pressure is too low, high-temperature steam easily from from steam inlet pipe 7 more close to steam vent 9 overflow, then steam maldistribution in deoxygenator, causes deaerating effect also bad.Therefore, sub-steam pipe 8 is designed to inner sleeve, outer sleeve-type structure, reduce sub-steam pipe 8 internal capacity, then high-temperature steam enters after in sub-steam pipe 8 from steam inlet pipe 7, steam pressure difference in space between inside and outside sleeve pipe 11,12 will reduce, make the high-temperature steam that gushes out from each steam vent 9 evenly.The ratio of outer tube 12 internal diameter and inner sleeve 11 external diameter is 2, is so more conducive to sub-steam pipe 8 internal pressure average.
In technique scheme, the internal diameter of described outer tube 12 is 1700-1800mm, and the internal diameter of described steam inlet pipe 7 is 650-750mm, and preferred outer tube 12 internal diameter is 1750mm, steam inlet pipe 7 internal diameter is 700mm, is so conducive to vapor diffusion in point vapour device 6 and high-temperature steam enters sub-steam pipe.
In technique scheme, described trickle comb layer 4 is 800-900mm with skinning device 3 spacing, trickle comb layer 4 is 80-100mm with the spacing of packing layer 5, and preferred trickle comb layer 4 is 850mm with skinning device 3 spacing, and trickle comb layer 4 is 90mm with the spacing of packing layer 5.Because the water of rotating-film deaerator and the heat exchange of steam mainly export 450mm place in skinning device 3 lower end, this section of deaerated water is atomizing state, and layer 4 of being combed by trickle is set to 850mm with skinning device 3 spacing, is conducive to thermal exchange and the deoxygenation of steam and deaerated water.Layer 4 of being combed by trickle is set to the spacing of packing layer 5 persistence that 90mm then increases deoxygenation, meets the deoxygenation demand of deaerated water.
In technique scheme, described packing layer is efficient regular wire packing Ω ring filler layer.This packing layer not only has high heat transfer efficiency, also has long service life.High temperature resistant indeformable advantage.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
