Description
Technical field
The present invention relates to indirect air cooling steam turbine Hai Le system injection type condenser.
Background technology
Injection type condenser is the direct-contact type condenser that Hungary EGI company develops, and is to have adopted the diaphragm type nozzle with the difference of other direct-contact type condenser.According to the experiment experience of EGI, adopting diameter is that 13mm and 15mm nozzle are better, and the injection pressure head of nozzle can form stable moisture film in 0.6～2.5m water column scope.According to applicant's experimental data, the best injection pressure head scope of nozzle film-formation result is 1～1.5 meter water column.Paper " research of the injection type condenser nozzle " record that " steam turbine technology " the 43rd volume the 3rd periodical is stepped on: Harbin Turbine injection type condenser nozzle evidence, the best pressure differential range of φ 13 nozzle film forming is 9.52KPa～15KPa, the best pressure differential range of φ 15 nozzle film forming is 10.88KPa～6KPa, when pressure reduction is greater than 16KPa before and after the nozzle, in the moisture film column current will appear.Therefore, the design of the height of hydroecium generally is no more than 1.5 meters in the injection type condenser, short transverse arrangement of nozzles row number can not surpass 6 rows, and (two sides of hydroecium are arranged 6 rows respectively in each, as shown in Figure 1), otherwise go up row most and descend row's differential static pressure too big most, it is less than normal and a few row pressure differences are bigger than normal down to go up a few row's nozzle pressure reduction, and film-formation result is poor.
For large-capacity air-cooled unit more than the 600MW, the water yield is big, and the nozzle quantity that needs is many, still adopt existing hydroecium structure, because above-mentioned factor can cause injection type condenser length long, influences the injection type condenser serviceability, has limited the application of injection type condenser on the large-scale air cooling unit.
Summary of the invention
Purpose of the present invention, be to overcome the interior hydroecium of existing injection type condenser individual layer can only arrange six row's nozzles, cause the above large-capacity air-cooled unit injection type condenser length of 600MW long, influence injection type condenser serviceability shortcoming, a kind of injection type condenser of the better performances of using for 600MW and above large-capacity air-cooled unit is provided.
Technical solution of the present invention is:
A kind of injection type condenser comprises shell and the interior hydroecium that is arranged in the shell, and the outer wall of shell has outer water chamber, communicates with interior hydroecium; Two sides of hydroecium are furnished with many row's membrane type nozzles respectively in described; Described inside and outside hydroecium is the sandwich construction of arranging along short transverse, and two of hydroecium sides are furnished with 4～6 row's membrane type nozzles respectively in each layer.
Described inside and outside hydroecium is two-layer or three layers.
Useful technique effect of the present invention:
Hydroecium injection type condenser design philosophy is to expand above-below direction to arrange nozzle space in the multilayer of the present invention, interior hydroecium height is increased, with dividing plate which floor interior hydroecium is divided into from above-below direction then, because up and down space and external pipe arrangement constraints, interior hydroecium can be divided into 3 layers at most from top to bottom.Hydroecium has been separated, the differential static pressure of water is only influential at this layer, hydroecium can be arranged 4～6 row's nozzles in each layer so from top to bottom, can make the above large-capacity air-cooled unit injection type condenser of 600MW respectively arrange the injection pressure head of nozzle all at optimum range, the length of injection type condenser is also in the reasonable scope controlled, to guarantee the condenser performance.

The specific embodiment
Now the injection type condenser with double-deck hydroecium is an example, describes the present invention in detail.
Referring to Fig. 3, Fig. 4: hydroecium 2 in being provided with in this injection type condenser 1, in hydroecium is separated into dividing plate 2-1 in each hydroecium 2-2 and down in hydroecium 2-3, be furnished with a few row's nozzle 2-4 on the hydroecium 2-2 in going up, under be furnished with a few row's nozzle 2-5 on the interior hydroecium 2-3; Injection type condenser 1 end plate 3 is provided with outer water chamber 4, each outer water chamber 4 also is separated into 4-2 of outer water chamber and the following 4-3 of outer water chamber with dividing plate 4-1, be connected to outer water chamber's water inlet on the last 4-2 of outer water chamber and take over 4-4, be connected to down outer water chamber's water inlet on the following 4-3 of outer water chamber and take over 4-5; Fig. 2 sees in the cooling water control system that enters hydroecium injection type condenser in the multilayer, and cooling water is divided into two-way, is provided with stop valve 5, the pressure regulation hydraulic turbine 6 and bypass valve 7 on the way, and another road is provided with stop valve 8, the pressure regulation hydraulic turbine 9 and bypass valve 10.
In order to eliminate the influence of the discrepancy in elevation to hydrostatic, interior hydroecium 2 and outer water chamber 4 all are separated into upper and lower hydroecium with dividing plate, the hydraulic pressure of upper and lower hydroecium is regulated separately, the hydraulic pressure of upper tank is regulated by the pressure regulation hydraulic turbine 6 and bypass valve 7, and the hydraulic pressure of lower header is regulated by the pressure regulation hydraulic turbine 9 and bypass valve 10.The cooling water that comes from cooling tower is divided into two-way, one the tunnel through stop valve 5, the pressure regulation hydraulic turbine 6 and bypass valve 7 are taken over 4-4 from the water inlet of last outer water chamber and are entered the 4-2 of outer water chamber, again to last interior hydroecium 2-2, be ejected into above the interior water fender 11 of injection type condenser 1 housing through a lot of upper tank nozzle 2-4, form the very thin moisture film of a lot of, these moisture films are formed passage one by one, the steam that comes with turbine low pressure cylinder carries out heat exchange, part steam is condensed into water, the water fender of being located between two interior hydroeciums 11 can prevent to collide mutually from the moisture film of two interior hydroeciums ejections, more helps moisture film and steam contact heat-exchanging; Simultaneously, another road is taken over 4-5 through stop valve 8, the pressure regulation hydraulic turbine 9 and bypass valve 10 from the water inlet of following outer water chamber and is entered down the 4-3 of outer water chamber, hydroecium 2-3 in arriving down again, be ejected in injection type condenser 1 housing through a lot of lower header nozzle 2-5, form the very thin moisture film of a lot of, these moisture films are formed passage one by one, carry out heat exchange with those remaining steam, and this part residual steam is condensed into water.Multilayer hydroecium structure, nozzle row number on every layer of hydroecium short transverse is few, the injection pressure reduction that can make every row's nozzle is all in optimum range, the moisture film forming effect of ejection is good, avoided single in hydroecium short transverse top nozzle row number arrange that too much, respectively to arrange the nozzle differential static pressure excessive and nozzle pressure differential range that cause is big, portion nozzle moisture film instability and the less shortcoming of moisture film area.Simultaneously, owing to effectively utilized height space, make short transverse can arrange that nozzle number increases, also just can shorten the length of injection type condenser, make the application of injection type condenser on the large-scale air cooling unit become possibility, and can guarantee that injection type condenser is unlikely long and influence its serviceability.
