Description
Technical field
The utility model belongs to steam turbine technical field of power generation, is specifically related to steam turbine generating steam pipe system.
Background technique
In heat energy power-generating factory, steam line carries hot steam to steam turbine generator set, for steam turbine provides power source from boiler.In cogeneration factory, the generator set of different size can be installed conventionally to the heat energy in whole power generation system is farthest utilized; such as the combination of medium temperature and medium pressure (3.43Mpa, 435 ℃) unit and time high temperature sub-high pressure (5.88Mpa, 485 ℃) Turbo-generator Set, or the compound mode of High Temperature High Pressure, inferior high temperature sub-high pressure, medium temperature and medium pressure.When these combination steam turbine generator set operate, the energy of whole power generation system is to have changed into as much as possible electric energy, but when wherein the energy supply equipment of generator set of one group breaks down or overhauls, because the parameter value of the needed power source of generator set of each group differs larger, so corresponding generator set can not move, moreover, the steam flow providing due to steam main is constant, make other generator set oeprations at full load, remaining steam makes other boilers give as security load operation, causes energy waste.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of steam, energy-conservation, safe steam turbine generating steam pipe system of making full use of.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
Technological scheme one: steam turbine generating steam pipe system, comprise the steam line group being formed by the valve on boiler, steam line, steam line and steam turbine, steam line is transported to steam turbine by steam from boiler; Steam line group comprises high temperature and high pressure steam pipeline group, inferior high temperature sub-high pressure steam line group and medium temperature and medium pressure steam line group, the steam line UNICOM of each steam line group, between the steam line of two steam line groups, be provided with temperature and pressure modulating valve, the two ends of temperature and pressure modulating valve connect respectively steam line and the valve of corresponding steam line group.
Such scheme compared with prior art, tool has the following advantages: 1, when the generator set of a certain group breaks down or overhauls, can close corresponding valve makes the pipeline of steam supply stop steam supply, open temperature and pressure modulating valve and corresponding valve between this group steam line and other group steam lines simultaneously, steam in pipeline is boosted heat up or step-down cooling is used for the generator set of other groups, the energy in whole power generation system is used substantially, avoid the oepration at full load of group of motors, and the signature load operation of boiler; 2, the pipeline and the valve that by the two ends at temperature and pressure modulating valve, connect different size, to guarantee that the steam that higher temperatures is pressed does not damage the steam line group that lower temperature is pressed.
Technological scheme two: press for fear of unit overtemperature after the chaser that breaks down suddenly, on the unicom pipeline of temperature and pressure modulating valve, be equipped with safety valve and the electronic valve of dispersing, safety valve, electronic valve in valve and steam line group and the steam turbine generator set interlocking dispersed are interlocked are simultaneously opened electronic diffusion valve and safety valve cuts out the valve in corresponding steam line group when the unexpected chaser of steam turbine.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model steam turbine generating steam pipe system.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, steam turbine generating steam pipe system, comprise medium temperature and medium pressure boiler 11, medium temperature and medium pressure steam line 12, medium temperature and medium pressure valve 13 on medium temperature and medium pressure steam line 12 and medium temperature and medium pressure steam turbine 14, inferior high temperature sub-high pressure boiler 21, inferior high temperature sub-high pressure steam line 22, inferior high temperature sub-high pressure valve 23 on inferior high temperature sub-high pressure steam line 22 and time high temperature sub-high pressure steam turbine 24, high-temperature high-pressure boiler 31, high temperature and high pressure steam pipeline 32, inferior high temperature sub-high pressure high-temperature high pressure valve 33 and High Temperature High Pressure steam turbine 34 on high temperature and high pressure steam pipeline 32, between medium temperature and medium pressure steam line 12 and time high temperature sub-high pressure steam line 22, be connected with time cooling time decompression regulating valve 1, between inferior high temperature sub-high pressure steam line 22 and high temperature and high pressure steam pipeline 32, be connected with the high decompression regulating valve 2 of high cooling, inferior cooling time decompression regulating valve 1 and high high decompression regulating valve 2 two ends that lower the temperature are connected respectively steam line and the valve (not shown) of corresponding steam line group, when medium temperature and medium pressure steam turbine 14 breaks down or overhauls, can close medium temperature and medium pressure valve 13 makes medium temperature and medium pressure steam line 12 stop steam supply, open time cooling time decompression regulating valve 1 between medium temperature and medium pressure steam line 12 and time high temperature sub-high pressure steam line 22 simultaneously, make the steam in medium temperature and medium pressure steam line 12 boost intensification for inferior high temperature sub-high pressure steam turbine 24 uses, or when time high temperature sub-high pressure steam turbine 24 breaks down or overhauls, can close time high temperature sub-high pressure valve 23 makes time high temperature sub-high pressure steam line 22 stop steam supply, open time cooling time decompression regulating valve 1 between time high temperature sub-high pressure steam line 22 and medium temperature and medium pressure steam line 12 simultaneously, make the steam in time high temperature sub-high pressure steam line 22 carry out decrease temperature and pressure for 14 uses of medium temperature and medium pressure steam turbine, other generator set the like, the energy in whole power generation system is used substantially, avoid the oepration at full load of group of motors, and the signature load operation of boiler.The steam line and the valve (not shown) that at inferior cooling time decompression regulating valve 1 and high cooling high decompression regulating valve 2 two ends, are connected respectively corresponding steam line group, to guarantee that the steam that higher temperatures is pressed does not damage the steam line group that lower temperature is pressed, simultaneously, for fear of unit overtemperature after the chaser that breaks down suddenly, press, on the unicom pipeline of inferior cooling time decompression regulating valve 1 and the high decompression regulating valve 2 of high cooling, be equipped with safety valve and the electronic valve of dispersing, safety valve, electronic valve and the steam turbine generator set interlocking of dispersing in valve and steam line group, when the unexpected chaser of steam turbine, interlock simultaneously and open electronic diffusion valve and safety valve cuts out the valve in corresponding steam line group.
