Abstract
A kind of thermal power plant regular unloading container draining heat and working medium recycling system, comprise continuous blowdown flash tank, regular unloading container, regular unloading container connects water-water heat exchanger entrance one end by surely arranging draining booster one tunnel, drainage pipeline after water-water heat exchanger exit end connection heat exchanger, another road connects heat supply network recirculated water water return pipeline, and condensate booster pump outlet conduit is connected by water-water heat exchanger and lowly adds entrance condensing water conduit.The utility model arranges sewer heat surely and working medium all reclaims at Heating Period, reduces turbine heat rate, saves heat supply network demineralized water rate of water make-up, reduces simultaneously and surely arranges the draining cooling tank cooling water water yield; Lowly entrance condensing water conduit is added because condensate booster pump outlet conduit is connected by water-water heat exchanger, so surely arrange sewer heat-setting water, blowdown heat recovery is to steam turbine heat regenerative system, reduce unit hear rate, reduce simultaneously and surely arrange the draining cooling tank cooling water water yield.
Description
Technical field
The utility model belongs to power plant drum boiler regular unloading container draining heat and working medium recovery technology, and the regular unloading container draining especially relating to the thermal power plant unit of low capacity is reclaimed.
Background technology
In current power plant system design, boiler blowdown water is by arranging continuous blowdown flash tank and regular unloading container system recoveries part working medium and heat, but surely arrange draining and all drain into cooling tank, its working medium and heat waste, especially small unit, it does not arrange precision processing device of condensation water or processing accuracy is not high, this part blowdown working medium and thermal loss especially serious.
Utility model content
The purpose of this utility model is to reclaim power plant regular unloading container draining heat and working medium, reduces unit hear rate, energy-saving and emission-reduction.
For achieving the above object, the utility model provides a kind of thermal power plant regular unloading container draining heat and working medium recycling system, comprise continuous blowdown flash tank, regular unloading container, continuous blowdown flash tank is communicated with regular unloading container to surely arranging drainage pipeline by platoon, regular unloading container also with determine row's blow-off line and carry out periodical blowdown pipeline from boiler body to be connected, it is characterized in that: regular unloading container connects water-water heat exchanger entrance one end by surely arranging draining booster one tunnel, drainage pipeline after water-water heat exchanger exit end connection heat exchanger, another road connects heat supply network recirculated water water return pipeline, condensate booster pump outlet conduit is connected by water-water heat exchanger and lowly adds entrance condensing water conduit.
Compared with prior art, the utility model is because regular unloading container is by surely arranging connection water-water heat exchanger entrance one end, draining booster one tunnel, drainage pipeline after water-water heat exchanger exit end connection heat exchanger, another road connects heat supply network recirculated water water return pipeline, therefore row's sewer heat and working medium all reclaim at Heating Period surely, reduce turbine heat rate, save heat supply network demineralized water rate of water make-up, reduce simultaneously and surely arrange the draining cooling tank cooling water water yield; Lowly entrance condensing water conduit is added because condensate booster pump outlet conduit is connected by water-water heat exchanger, so surely arrange sewer heat-setting water, blowdown heat recovery is to steam turbine heat regenerative system, reduce unit hear rate, reduce simultaneously and surely arrange the draining cooling tank cooling water water yield.
Accompanying drawing explanation
Fig. 1 is the utility model detailed description of the invention structure chart.
Detailed description of the invention
As shown in Figure 1,1, continuous blowdown flash tank, 2, regular unloading container, 3, surely draining booster is arranged, 4, water-water heat exchanger, 5, condensate booster pump, 6, platoon is to surely arranging drainage pipeline, 7, periodical blowdown pipeline is carried out from boiler body, 8, surely arrange drainage pipeline, 9, drainage pipeline after heat exchanger, 10, condensate booster pump outlet conduit, 11, lowly entrance condensing water conduit is added, 12, heat supply network recirculated water water return pipeline, 13, surely arrange blow-off line
The utility model comprises continuous blowdown flash tank 1, regular unloading container 2, continuous blowdown flash tank 1 is communicated with regular unloading container 2 to surely arranging drainage pipeline 6 by platoon, regular unloading container 2 also with determine row's blow-off line 13 and carry out periodical blowdown pipeline 7 from boiler body to be connected, regular unloading container 2 connects water-water heat exchanger 4 entrance one end by surely arranging draining booster 3 one tunnel, drainage pipeline 9 after water-water heat exchanger 4 exit end connection heat exchanger, another road connects heat supply network recirculated water water return pipeline 12, condensate booster pump outlet conduit 10 is connected by water-water heat exchanger 4 and lowly adds entrance condensing water conduit 11.
Main working process is: carry out platoon drainage pipeline by continuous blowdown flash tank and enter regular unloading container with the sewer carrying out periodical blowdown pipeline from boiler body, water after dilatation squeezes into water-water heat exchanger through surely arranging drainage pipeline by when draining booster is in summer surely, export condensate water carry out heat exchange with low the adding after boosting through condensate booster pump, the condensate water after heat exchange is back to and lowly adds entrance condensing water conduit; Time in the winter time, draining is returned to heat supply network recirculated water water return pipeline through draining booster surely surely.
