Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment 1
Steam assists a nozzle assembly for attemperator, is arranged on main steam line 1, comprises nozzle 2, desuperheating 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 preferably has annular cross section, axially extends to the elongated pipeline section form of the other end from one section.
Desuperheating water conduit 3 and steam lead 4 radially penetrate main steam line 1, and desuperheating water tubes connection is described nozzle 2 extremely, for providing cooling water to described nozzle 2; Steam lead 4 is connected to described nozzle 2, for providing atomizing steam to described nozzle.Desuperheating water conduit 3 and steam lead 4 are arranged on the outside of main steam line radial direction, the setting that desuperheating water conduit and steam lead can be almost parallel, and are fixed by mounting flange 5 and main steam line.
Described nozzle 2 comprises housing 2.1, is provided with desuperheating water deflector 2.2 in housing, and its one end is communicated with described desuperheating water conduit, and the other end has be communicated with atomising head 2.3 open and exports, and described desuperheating water deflector defines described desuperheating water flow path; Steam deflector 2.4, its one end is communicated with described steam lead, and the other end has be communicated with atomising head 2.3 open and exports.
Further, described nozzle 2 has a mixed flow section 2.5, the open outlet of desuperheating water deflector is all communicated with the initiating terminal of mixed flow section 2.5 with open outlet of steam deflector, the end of mixed flow section 2.5 is communicated with atomising head 2.3, in mixed flow section, auxiliary steam high speed impact desuperheating water forms water mists, desuperheating water is mixed more abundant with auxiliary steam, in mixed flow section, the size of single drop is usually little than the drop in mechanical atomization attemperator, therefore, what evaporate in main steam line is faster.Therefore, this product can be used in the application of shorter downstream line length acquisition.
The Way out of atomising head is identical with vapor flow direction in main steam line, can reduce desuperheating water and cause eddy current and whirlpool in the flowing of process vapor, and minimizing may cause less desirable vibration or or other less desirable impacts on attemperator.Further, the central shaft of atomising head overlaps with the central shaft of main steam line, mixes more uniformly after desuperheating water is atomized with the process vapor in main steam line.
In order to improve atomizing effect, desuperheating water deflector has one along the sprue of its axial distribution and several runners of being communicated with this sprue, the end of runner is communicated with mixed flow section, preferably, sprue and runner vertical distribution, and the auxiliary steam in steam lead is identical with mixed flow section direction after steam deflector, auxiliary steam and the desuperheating water flowed through runner form front and intersect and impact, desuperheating water is mixed more abundant with auxiliary steam, the drop of formation is more tiny.
The number of mixed flow section is identical with the number of runner, and one_to_one corresponding is communicated with.
When introducing element of the present invention or its embodiment, article " ", " being somebody's turn to do " and " described " are intended to refer to there is one or more element.Term " comprises ", " comprising " and " having " be intended to be inclusive, means can there is add ons except the element listed.Term as " on " D score " left side " " right side " " interior ", " outward " be based on orientation shown in the drawings or position relationship, be only the present invention for convenience of description instead of require that the present invention with specific azimuth configuration and operation, therefore must can not be interpreted as limitation of the present invention.
