The hydrophobic flash vessel of this steam has the high temperature of being applicable to a high pressure operating mode, characteristics that can the erosion of anti soda, and conventional hydrophobic flash vessel equipment reliability is high, and the maintenance cost is low, can guarantee the operation safety of hydrophobic flash vessel.
Description
Technical field
The utility model relates to a kind of steam drainage dilatation device, is specifically related to the steam drainage flash vessel of a kind of vapour water erosion.
Background technology
Steam drainage flash vessel equipment is generally used for power station and hydrophobic in elevated pressures and temperature hydrophobic pipeline is carried out dilatation step-down, isolate steam and hydrophobic, steam is introduced in interchanger, make full use of its heat energy, hydrophobic, it is introduced in drain tank and regularly sends into water feeding system; Dewatering capacity-enlarging device is mainly used in reducing pressure, if high pressure steam directly enters condenser or other interchanger, it is easy to causes the interchanger superpressures such as condenser to damage, can reduce pressure by dewatering capacity-enlarging device, avoid superpressure, protection upstream device.
Conventional steam drainage flash vessel is generally a vertical or horizontal carbon steel metal container, is provided with the hydrophobic water-in of pipeline, secondary steam outlet, two hydrophobic outlets etc., lacks antiscour inner member, as shown in Figure 1 in container. Owing to vapour line drain water piping is directly welded on dewatering capacity-enlarging device; after carbonated drink medium enters dewatering capacity-enlarging device from hydrophobic inlet pipeline; due to abrupt pressure reduction; the sharply dilatation of carbonated drink medium, accelerates erosion flash vessel inwall, very easily causes the erosion of flash vessel wall thickness to subtract thin; even bore a hole; in the work-ing life of reduction equipment, increase maintenance load, and the shutdown of power station unit may be caused.
Practical novel content
The technical problems to be solved in the utility model is to provide the steam drainage flash vessel of a kind of vapour water erosion, it is possible to alleviate the erosion of steam-water pipe for container inner wall largely, it is to increase the work-ing life of dewatering capacity-enlarging device.
For solving the problems of the technologies described above, the steam drainage flash vessel of a kind of vapour water erosion of the utility model, this device comprises container body, is positioned at the secondary steam venting port of container body one end, is positioned at the hydrophobic outlet of container body one end, is positioned at the thin conduit assembly of inwall in the middle part of container body, hydrophobic pipe element end passes container body, dredges conduit assembly and has offered several row's rectangle aperture for being positioned in container body section.
This device also comprises the anti-erosion backplate being positioned at dewatering capacity-enlarging device inwall.
This device also comprises the vortex eliminator being positioned at hydrophobic outlet inside.
This device also comprises the water separator being positioned at secondary steam venting port.
Vortex eliminator is the cruciform steel plate of a welding, and its one end is welded in a circular steel plate, and the other end is welded in hydrophobic exit.
Advantageous Effects of the present utility model is: this steam drainage flash vessel has and is applicable to high temperature and high pressure condition, can the feature of vapour water erosion, more conventional dewatering capacity-enlarging device equipment dependability height, maintenance cost is low, can ensure the operating safety of dewatering capacity-enlarging device.

In figure: 1, dredge conduit assembly; 2, anti-erosion backplate; 3, vortex eliminator; 4, water separator; 5, secondary steam venting port; 6, hydrophobic outlet.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the steam drainage flash vessel of a kind of vapour water erosion of the utility model, this device comprises container body 7, it is positioned at the secondary steam venting port 5 of container body 7 upper end, it is positioned at the hydrophobic outlet 6 of container body 7 times ends, the thin conduit assembly 1 and the end that are positioned at inwall in the middle part of container body 7 pass container body 7, dredging conduit assembly 1 is built-in drain nozzle, built-in drain nozzle is connected, built-in drain nozzle has been offered several row decompression rectangle aperture, real medium discharge area is greater than pipeline section and amasss, hydrophobic from aperture, spray rapid volume-expanding pressure-reducing with certain speed. owing to adopting aperture decompression technology, rapidly hydrophobic, energy hastens to decay soon, and washing away of being avoided by container weakens greatly, reduces the vibratory noise in operation simultaneously.
This device also comprises the anti-erosion backplate 2 being positioned at dewatering capacity-enlarging device inwall, the area of inner liner stainless steel can be determined according to built-in hydrophobic pipe quantity, the anti-area rushing stainless steel is not less than 3 times of hydrophobic inlet pipeline area, and be welded with built-in hydrophobic pipe, carbonated drink medium can be avoided for the direct impact of drain tank inwall, strengthen the anti-erosion property of housing.
This device also comprises the vortex eliminator 3 being positioned at hydrophobic outlet 6 inside, and vortex eliminator 3 is the cruciform steel plate of a welding, and its one end is welded in a circular steel plate, and the other end is welded in hydrophobic outlet 6 place. Avoid dewatering capacity-enlarging device pressure sharply to reduce, and reduce eddy current to the impact of dewatering capacity-enlarging device.
This device also comprises the water separator 4 being positioned at secondary steam venting port 5, water separator 4 is the band pore plectane of two layers, avoid dewatering capacity-enlarging device pressure sharply to reduce the medium dilatation brought to impact, decrease the moisture in steam simultaneously, reduce the possibility that tube bank in condenser is subject to water droplet impingement and destroys.
During work, steam drainage pipeline is connected with the hydrophobic inlet connection 1 of dewatering capacity-enlarging device, and secondary steam venting port 5 is connected to the interchanger that system uses secondary steam; Hydrophobic outlet 6 is connected to and receives hydrophobic hydrophobic casing. This steam drainage flash vessel is arranged on the pipeline between steam drainage pipeline to hydrophobic casing, start with under normal stoppage in transit operating mode at the heat power equipment such as steam-turbine unit or boiler, receive the steam drainage from hydrophobic pipeline, carry out after step-down dilatation is separated with carbonated drink, steam is introduced in interchanger, make full use of its heat energy, hydrophobic, it is introduced into drain tank.
