Description
Technical field
The utility model relates to a kind of superheated steam cooling device that is used in the surface horizontal heater, can be used for the feed-water heater of power station industry, chemical industry, belongs to the feed-water heater technical field.
Background technology
The surface horizontal feed-water heater is to utilize steam to come the heat exchanger of heating boiler or other feedwater.Be not provided with the superheated steam cooling section at conventional at present surface horizontal feed-water heater, need reduce to saturated vapor to superheated steam when using the very high Steam Heating of the degree of superheat to feed water, independently external superheated steam cooler perhaps is set, the former is the way that reduces the steam grade, can not farthest improve system thermal efficiency, the latter then can increase investment and plant area, if superheated steam directly enter heater in the hope of reduce its grade also can be owing to its thermal shock is too big damage equipment.
Summary of the invention
The purpose of this utility model is that invention a kind ofly can farthest improve the outlet temperature of feedwater, and can eliminate the thermal shock of high-temperature steam to equipment, reaches the superheated steam cooling device in the surface horizontal heater of being used for of device security.
For realizing above purpose, the technical solution of the utility model provides a kind of superheated steam cooling device that is used in the surface horizontal heater, it is characterized in that, form by interior involucrum, pull bar, arc, dividing plate, steam baffle, outer envelope, insulation board, insulation board, arc, interior involucrum and outer envelope constitute a semi-cylindrical end sealing, the unlimited inner chamber of the other end, inner chamber is provided with the dividing plate of layout straggly up and down, the pull bar that passes dividing plate places in the inner chamber, two ends place outside the inner chamber, the top of involucrum in steam baffle places.
Whole cooling device is embedded in top in the surface horizontal heater, and interior involucrum is separated into inside and outside two parts with chamber, links to each other by the opening on the outer envelope, and insulation board is a side of sealing in a side of steam cooling section, and steam inlet is positioned at the outer envelope top.
Superheated steam in the steam cooling device with the flow rate of the best, can be expeditiously with heat transferred water, and because vapor (steam) temperature is very high, the thermograde of conducting heat is big, can farthest improve the outlet temperature of feedwater, the utility model has been removed from set up independent steam condenser outside heater, reduces resistance loss of pipeline and plant maintenance workload, and investment reduces greatly.
The utility model has the advantages that and farthest to improve the outlet temperature of feedwater, and can eliminate the thermal shock of high-temperature steam, reach the purpose of device security, reduce cost, reduce the place consumption equipment.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, 2, for being used for the superheated steam cooling device structural representation in the surface horizontal heater, the described superheated steam cooling device that is used in the surface horizontal heater is made up of interior involucrum 1, pull bar 2, arc 3, dividing plate 4, steam baffle 5, outer envelope 6 and insulation board 7.
By insulation board 7, arc 3 and interior outer envelope manufacture semi-cylindrical end sealing, the inner chamber that the other end opens wide, inlay and be installed in the surface horizontal heater 8, interior involucrum 1 is separated into inside and outside two parts with chamber, link to each other by the opening on the outer envelope 6, insulation board 7 is in a side of bore seal, in interior involucrum 1 the inside, set dividing plate 4, and pull bar 2 passes in dividing plate 4, dividing plate is layout straggly about in the of 4, and by pull bar 2 location, the top of involucrum 1 in steam baffle 5 places, on outer envelope 6 and interior involucrum 1, opening is arranged all, the opening of outer envelope 6 links to each other with the steam connection seat of surface horizontal heater 8 upper ends, and steam just enters outer envelope 6 by this, then the cross-current mistake, down enter inner chamber by interior involucrum 1 opening again, and in the restriction current downflow of dividing plate 4.
During work, the superheated steam that comes from steam turbine enters outer envelope 6 by the steam connection seat 9 of surface horizontal heater 8 upper ends, lateral flow is to an end of insulation board 7 in outer envelope 6, enter interior involucrum 1 from the perforate of outer envelope 6, stainless steel steam baffle 5 is installed in outer envelope 6 is avoided involucrum 1 in direct impact of steam of HTHP, then be equipped with dividing plate 4 in the interior involucrum 1 and pull bar 2 fixes heat exchanger tube 11, superheated steam just carries out heat exchange with feedwater in this zone, feedwater enters heat exchanger tube 11 from the import 10 of surface horizontal heater 8 lower ends, through flowing out from the outlet 12 of surface horizontal heater 8 upper ends with steam heat exchange back, dividing plate 4 adopts specific cutting form, force steam to skim over heat exchanger tube 11 with rational horizontal and vertical flow velocity, under the effect of pressure reduction, in dividing plate, force in flowing with heat exchanger tube 11 in feedwater conduct heat, flow into the steam section of condensing at the other end then through opening wide, to greatest extent heat is passed to feedwater and guaranteed that tube bank does not produce excessive vibrations, insulation board 4 has certain distance from the heater tube sheet, isolated a part of heat, make the suffered thermal shock of tube sheet among the scope that can bear, its temperature is near saturation temperature, can farthest utilize the degree of superheat of steam, can guarantee that again exporting steam is dry saturated steam, can not cause and wash away heat-transfer pipe.
