Description

A kind of coal-burning power plant high back pressure condensate system
Technical field
This utility model relates to a kind of coal-fired plant's high back pressure heating system field, particularly relates to a kind of coal-burning power plant highback Pressure condensate system.
Technical background
At present, the heat supply in each large, medium and small city of China is not up to oepration at full load, and heating demand utilization rate is low, high back pressure Heat supply will be a kind of novel heat supply scheme.After the steam drive device turbine generator group generating that Hazards in Power Plant boiler produces, put The steam gone out contains major part heat, and pressure is the highest.Generally, the exhaust steam that unit air-cooled steam turbine is discharged is exhausted directly to Air-Cooling Island, the minor heat in exhaust steam is utilized by recirculated cooling water, and major part heat is discharged in air as a vapor, Causing energy waste so that need the more coal that burns in heat supplying process, environmental pollution is more serious, meanwhile, and high back pressure Water content in steam turbine reduces, it is desirable to provide more water from the external world.
Utility model content
In order to overcome above-mentioned prior art not enough, this utility model provides a kind of coal-burning power plant high back pressure and condenses water system System.
This utility model be the technical scheme is that a kind of coal-burning power plant high back pressure condensate system, empty including unit Cold steam turbine, main exhaust, exhaust steam exhaustor, heat supply network condenser, condensate tank, vacuum electric valve, hydrophobic condensate pipe, valve Door, exhaust steam blow-down pipe, condensation water effuser, exhaust steam condense water mixing effuser, the steaming that described unit air-cooled steam turbine is discharged Vapour is discharged along main exhaust, and described main blow-off line arranges an exhaust steam exhaustor, and described exhaust steam exhaustor rear sets Put a heat supply network condenser, heat heat supply network recirculated water by heat supply network condenser surface heat exchanging, before described condenser entrance One vacuum electric valve is installed on exhaust steam pipeline, between described vacuum electric valve and condenser, is provided with condensate pipe, described Heat supply network condenser has three outflow pipelines, is exhaust steam blow-down pipe respectively, condenses water effuser and condensate pipe, described heat Condensation water in net condenser flows into condensate tank.
The beneficial effects of the utility model are: increasing heat supply network condenser in coal-burning power plant, it utilizes exhaust steam in steam turbine to heat Heat supply network recirculated water, improves energy utilization rate, it is achieved energy-saving and emission-reduction, and meanwhile, condenser reclaims high-temperature high-pressure apparatus abnormal precious Condensation water, and condenser can remove the oxygen condensed in water, increases water quality, prevents etching apparatus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of condenser in this utility model.
In figure: 1. unit air-cooled steam turbine, 2. main exhaust, 3. exhaust steam exhaustor, 4. heat supply network condenser, 5. condensation water Case, 6. vacuum electric valve, the most hydrophobic condensate pipe, 8. valve, 9. exhaust steam blow-down pipe, 10. condensation water effuser, 11. exhaust steam coagulate Bear water mixing effuser.
Detailed description of the invention
In order to be able to be more clearly understood that the technical solution of the utility model, further to this utility model below in conjunction with the accompanying drawings Explanation.
A kind of coal-burning power plant high back pressure condensate system as depicted in figs. 1 and 2, including unit air-cooled steam turbine (1), master Exhaustor (2), exhaust steam exhaustor (3), heat supply network condenser (4), condensate tank (5), vacuum electric valve (6), hydrophobic condensate pipe (7), valve (8), exhaust steam blow-down pipe (9), vapour condense water mixing effuser (10), exhaust steam condenses water mixing effuser (11), institute The steam that the unit air-cooled steam turbine (1) stated is discharged is discharged along the main exhaust (2) of DN500, the pipe of described main gland steam exhauster (2) Arranging the exhaust steam exhaustor (3) of a DN400 on road, part exhaust steam flows into exhaust steam exhaustor (3), described exhaust steam exhaustor (3) rear arranges a heat supply network condenser (4), heats heat supply network recirculated water by heat supply network condenser (4) surface heat exchanging, described Exhaust steam exhaustor (3) before heat supply network condenser (4) entrance is upper installs a vacuum electric valve (6), not only ensures to condense in water to contain There is very small amount of oxygen, and make heat contained in steam be used for as far as possible heating heat supply network recirculated water, described vacuum Being provided with the hydrophobic condensate pipe of DN300 (7) between electrodynamic valve (6) and condenser (4), described hydrophobic condensate pipe (7) uses valve (8) control flow, described heat supply network condenser (4) has three outflow pipelines, be that the exhaust steam that part exhaust steam is flowed out is vented respectively , there is, in preventing heat supply network condenser (4), the situation that pressure is excessive in pipe (9), discharges condense the water being cooled to liquid in order to exhaust steam after Condensation water effuser (10), and exhaust steam and condensation water mixing after flowing exhaust steam condense water mixing effuser (11), described Heat supply network condenser (4) in condensation water flow into condensate tank (5).
This utility model does not heats heat supply network recirculated water merely with exhaust steam in steam turbine, improves energy utilization rate, it is achieved energy-conservation subtract Row, and reclaimed condensation water highly important to high-temperature high-pressure apparatus, remove the oxygen condensed in water simultaneously, increase water quality.
The above is only better embodiment of the present utility model, therefore all according to described in this utility model patent claim Structure, feature and principle done equivalence change or modify, be all included in this utility model patent claim.
