Description
Technical field
The utility model relates to a kind of associating Air-Cooling Island of air-cooled cogeneration units, the pipe arrangement particularly between a kind of air-cooled cogeneration units Air-Cooling Island.
Background technology
Thermal power generation unit mainly contains the equipment such as connected boiler, steam turbine, generator and condenser.Thermal power generation unit operationally, under the exhaust steam condenser condensation timely and effectively of discharging after steam turbine work done.Greatly unit efficiency is affected to the quality of exhaust steam condensation effect after work done.Condensed condensed water returns boiler as boiler feed water.
After condensation work done the condenser of exhaust steam have with water be cooling medium condenser and take air as the condenser of cooling medium.
Air-Cooling Island is that cooling medium makes a kind of condenser of condensation to exhaust steam after Steam Turbine in Fire Power Plant work done with air.
Air-Cooling Island has the steam inlet pipe of level, the side of steam inlet pipe is uniform is connected with multiple row cooling unit, cooling unit has the horizontal distributing pipe being connected in steam inlet pipe side, on the downside of distributing pipe, the left and right sides of tube wall has the finned tube along the uniform oblique below of distributing pipe length direction respectively, the lower end of finned tube is connected with condensed water discharge pipe, and cooling unit has fixed gas discharge pipe.Air blast is needed below the finned tube that cooling unit is uniform.
During installation, the steam inlet pipe of Air-Cooling Island is connected with turbine low pressure cylinder blow-off line by inlet valve, the condensed water discharge pipe of Air-Cooling Island is connected with condensation water tank by condensation water valve, fixed gas discharge pipe is connected with fixed gas aspirator by fixed gas valve.
During use, after the work done that turbine low pressure cylinder blow-off line is discharged, exhaust steam enters in the finned tube of cooling unit by steam inlet pipe, air blast blows to the air of surrounding environment outside finned tube, finned tube gets off the exhaust steam condensation in finned tube to become condensed water as heat exchange unit, and fixed gas discharge pipe discharges the fixed gas produced in the pipe of cooling unit.
In the unit in thermal power plant, have and can produce electric energy, utilize again steam turbine generator to make the steam of merit to the cogeneration units of user's heating.Cogeneration units is the same with other thermal power generation unit, and be maintenance and for subsequent use and first, second two units design and construction is identical, every platform unit is connected with steam turbine and Air-Cooling Island.
For the cogeneration units providing heating heat to user, at non-heating period, the unit having two connected steam turbines and Air-Cooling Island to combine can be stopped transport a unit, only runs a unit.
Take Air-Cooling Island as the Air-Cooling Island condensing capacity of the cogeneration units of condenser be design by the nominal output of steam turbine, Air-Cooling Island uses in outdoor environment, along with the unit operation time increases, can dust and dirt be adsorbed with between the fin of finned tube, the condensing capacity of Air-Cooling Island is reduced.The reduction of Air-Cooling Island condensing capacity can cause the efficiency of cogeneration units to decline.
For improving the condensing capacity of the Air-Cooling Island that condensing capacity reduces after above-mentioned use a period of time, in prior art, have plenty of and at finned tube, demineralized water sprinkling equipment is installed outward or boiler feed water sprinkling equipment is installed in finned tube, during use, improve the condensing capacity of Air-Cooling Island by the method for shower water in finned tube or outside finned tube, it is pretty troublesome that Air-Cooling Island installs Water spray scrap build, expense is also higher, during use, consume a large amount of demineralized waters or boiler feed water, operating cost is also higher.Also have and increase by a row cooling unit again on steam inlet pipe, in order to improve the condensing capacity of Air-Cooling Island, increase by a row cooling unit, not only more bother, expense is higher.
Summary of the invention
