Embodiment 1
A kind of nozzle assembly of steam auxiliary attemperator, is arranged on main steam line 1, including nozzle 2, desuperheat water conduit
3, steam lead 4.Main steam line 1 is full of process vapor, and defines process vapor axial flow path, and jet chimney 1 is excellent
Selection of land has annular cross section, and the elongated pipeline section form of the other end is extended axially to from one section.
Desuperheat water conduit 3 and steam lead 4 are radially penetrated into main steam line 1, and desuperheat water conduit is connected to the nozzle
2, for providing cooling water to the nozzle 2；Steam lead 4 is connected to the nozzle 2, is steamed for providing atomization to the nozzle
Vapour.Desuperheat water conduit 3 and steam lead 4 are arranged on the outside of main steam line radial direction, and desuperheat water conduit and steam lead can
With substantially parallel setting, and fixed with main steam line by mounting flange 5.
The nozzle 2 includes shell 2.1, and desuperheating water deflector 2.2, one end and the desuperheat water conduit are equipped in shell
There is the open outlet being connected to atomising head 2.3, the desuperheating water deflector to define the desuperheat water flowing for connection, the other end
Path；Steam deflector 2.4, one end are connected to the steam lead, and the other end has to be opened to what atomising head 2.3 was connected to
Mouthful.
Further, the nozzle 2 has a mixed flow section 2.5, the open outlet of desuperheating water deflector and steam
The open outlet of deflector is connected to the initiating terminal of mixed flow section 2.5, end and the atomising head 2.3 of mixed flow section 2.5
Connection, in mixed flow section, auxiliary steam high speed impact desuperheating water forms water mists, desuperheating water is made to be mixed more with auxiliary steam
Fully, the size of single drop is usually smaller than the drop in mechanical atomization attemperator in mixed flow section, therefore, in main steam
It is evaporated faster in pipeline.Therefore, this product can be used in the application that shorter downstream line length obtains.
The export direction of atomising head is identical as steam flow direction in main steam line, it is possible to reduce desuperheating water is steamed in process
Cause vortex and whirlpool, reduction that may cause undesirable vibration or or other undesirable shadows on attemperator in the flowing of vapour
It rings.Further, the center overlapping of axles of the central shaft of atomising head and main steam line, make after desuperheat water atomization more uniformly with
Process vapor mixing in main steam line.
In order to improve atomizing effect, desuperheating water deflector has a sprue being axially distributed along it and connects with the sprue
The end of several logical runners, runner is connected to mixed flow section, it is preferred that sprue and runner vertical distribution,
And the auxiliary steam in steam lead is identical as mixed flow section direction after steam deflector, auxiliary steam with through runner stream
Dynamic desuperheating water forms front and intersects impact, so that desuperheating water is more fully mixed with auxiliary steam, the drop of formation is more tiny.
The number of mixed flow section is identical as the number of runner, and corresponds connection.
