Region so that the drop of steam entrained with is maintained at motion near barrel, it is to avoid liquid film enters steam drain along container wall
Pipe, reduces liquid film loss.
In order to prevent the gas of fluid eddies band flow separator bottom that steam trap connection formed from rotating, arrange steam trap connection
Go out, before described steam trap connection, vortex breaker is installed.
This utility model the steam-water separator obtained have the following characteristics that
1. this utility model simple in construction, cost is relatively low, and separation efficiency is higher, effect stability.
Equipment air intake pipe the most of the present utility model has downward-sloping angle, it is possible to effectively reduce liquid film loss.
Multiple air intake pipe the most of the present utility model is arranged symmetrically with, and makes have preferable symmetry into vapour, can reduce cylinder
The height of body, reduces manufacturing cost.
4. this utility model arranges baffle plate and liquidproof wriggling shirt rim, and the liquid film that reduces of high degree loses, the most also
Can effectively prevent into vapour short circuit.
5. this utility model is provided with conical plate, and its effect not only prevents vortex to contact with liquid level, by separated liquid
Body weight newly takes equipment out of, and meanwhile, pyramidal structure will not destroy and disturb cyclone to cause device efficiency to reduce.It addition, fall in taper
The drop on plate surface, because the gravity of itself can be imported into drop collecting region along inclined surface, thus improves equipment separation efficiency.
6. this utility model have employed vortex breaker, destroys the generation of vortex on liquid level, and in preventing from flowing, portion gas exists
Bottom is discharged, and impacts follow-up equipment, such as the cavitation erosion etc. of pump.
7. this utility model is by arranging the disturbing flow device such as porous plate and vortex breaker, it is possible to effectively control steam-water separator water
Position, prevents it from fluctuation occur, and ensures that drain will not produce jet blocking effect, affect equipment hydrophobic.
Accompanying drawing explanation
Fig. 1 is the steam-water separator structural representation of this utility model design.
Detailed description of the invention
The utility model will be further described to combine accompanying drawing below by embodiment.
Embodiment 1
As it is shown in figure 1, the steam-water separator that the present embodiment describes, including steam drain pipe 1, upper cover 2, air intake pipe 3, cylinder
Body 4, conical plate 5, steam trap connection 6, vortex breaker 7, low head 8, porous plate 9, liquidproof wriggling skirt 10 and cylindrical baffle 11.
Cylinder 4 welds with upper cover 2, low head 8, and air intake pipe 3 is two, is installed on cylinder 4 top, is separated by 180 ° of cloth
Put, the outer side bus of air intake pipe 3 and the cylinder 4 tangent setting of inwall, and air intake pipe 3 ecto-entad be inclined upwardly 5 °-15 °,
Wherein angle of inclination is optimal with 10 °.Conical plate 5 and porous plate 9 are installed in cylinder 4 bottom, and steam drain pipe is installed at upper cover 2 top
1 and cylindrical baffle 11, steam drain pipe 1 end installs liquidproof wriggling skirt 10, and low head 8 is installed steam trap connection 6 and anti-whirlpool
Device 7.Conical plate more than 5 is the separated region of vapour-liquid, is below the catcher of drop.
During work: when steam enters in housing cavity via air intake pipe 3, and air-flow is divided into two, and one moves upward, separately
One then moves downward.Because air intake pipe 3 is centrosymmetrically arranged, import gas symmetry is significantly increased.Due to air intake pipe 3
Eccentric setting, steam will along cylinder 4 wall formed spiral air flow.For preventing air-flow from arbitrarily spreading at upper cover 2, closing
Suitable position is provided with cylindrical baffle 11, limits the flow region of drop, makes the drop of entrained with in steam be maintained at cylinder
Near wall, motion, meanwhile, effectively prevent the short circuit of gas, in order to avoid entering vapour to be directly entered steam drain pipe 1.Steam-water separator is in fortune
Can generate liquid film, cylindrical baffle 11 and liquidproof wriggling skirt 10 during row can effectively promote liquid film to come off, and prevents liquid
Film enters steam drain pipe 1 along container wall, thus improves equipment separation efficiency.Additionally, the inlet angles degree of air intake pipe 3 also can
Enough effectively reduce liquid film loss.Equipment is divided into upper and lower two regions by conical plate 5, and its top is the separated region of vapour-liquid, bottom
For the catcher of drop, prevent vortex from contacting with liquid level.Conical plate 5 area below gas flow rate is extremely low, can effectively prevent from setting
The drop collected is rolled by the ascending air at standby center again, is entrained with equipment.Conical plate 5 and barrel maintain necessarily
Gap, to ensure that drop can enter conical plate 5 area below smoothly.In equipment running process, drop the most all can be because of
Centrifugal force that cyclone produces and be thrown toward wall, and flow downward along wall, or along with cyclone moves downward, eventually enter into cone
Among the gap of shape plate 5 and cylinder 4, thus arrive the effect of steam-water separation.Beat tiltedly it addition, conical plate 5 can continue to collect
Drop on face, and rely on drop deadweight to be conducted into collecting zone along the component on inclined-plane, optimize separating effect further.Collect
The water arrived all will be from steam trap connection 7 device for transferring.It is mounted with vortex breaker 7 and porous plate 9 on steam trap connection 6 top, destroys at liquid
The vortex formed on face, to avoid vortex afterbody to drive separator lower liquid to rotate, prevents gas therewith from steam trap connection 5 row
Go out, also prevent jet blocking effect simultaneously, it is ensured that the flow of steam trap connection 6.Air-flow after cylinder body bottom completes steam-water separation,
Move towards body centre, become the air-flow rotated up in the central area of cylinder, discharge from steam drain pipe 1.
