Description

Enclosed high-temperature steam condensation water recovery system
Technical field
The present invention relates to a kind of enclosed high-temperature steam condensation water recovery system.
Background technology
China's energy consumption increases faster than economic growth, and the per GDP energy consumption goes up not down, and the energy conservation situation is very severe.Show that according to related data China's per capita energy consumption is merely the half the of world average level, but GDP per capita can the high twice of loss-rate world average level, is 2.8 times of India, 4 times of the U.S., 8 times of Japan.Along with Chinese economic development, domestic energy demand constantly increases; And alleviate energy 'bottleneck' restrictions, to increase supply no doubt important by every possible means, but basic outlet be adhere to developing and practice thrift develop simultaneously, the policy of energy conservation priority, carry forward vigorously energy-saving and cost-reducingly, improve efficiency of energy utilization, give up this no other way.
A few days ago, the scheme that the waste hot steam of workshop reaction boiler is utilized has again obtained good effect, has not only obtained good benefit economically; Simultaneously also obtained good social benefit, in conjunction with the actual conditions of workshop, present stage is adopted open circulation to the high-temperature condensation water to the workshop; Waste comparatively serious situation; The mode that can adopt enclosed to reclaim is carried out the recovery of heat, thereby practices thrift steam loss, reduces energy consumption.Present steam utilization mode is as shown in Figure 1, and steam is blended in the condensation pond 3 through the lake water of drain valve 1 back and water pump 2 suction together, is going in the water treatment tank 5 to handle through condensate pump 4 is laggard, and then behind boiler feed pump 6, is flowing in the boiler 7.This mode has following shortcoming:
(1) a large amount of drain valve leakage vapour and flash distillation secondary vapour discharge sky, and this part waste accounts for 5~20% of condensate total amount, 20~60% of total amount of heat.
(2) discharging of flash steam, winter hot mist boundless, summer, heat wave was pressing, promptly environment was caused serious thermal pollution, possibly scald personnel again, had potential safety hazard.
(3) the direct and untreated river of the water that reclaims mixes, and as cooling, quality descends, and has caused bigger waste.
In addition, recycle-water adopts the recycle-water pipeline of underground installation carbon steel, makes dense water flow automatically to dense water storage tank; Because pipeline is buried underground for a long time, is easy to make pipeline generation corrosion phenomenon, causes pipe leakage; So both caused the waste of water, pipeline also is difficult for repairing, and wastes comparatively serious.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of enclosed high-temperature steam condensation water recovery system.The technological means that the present invention adopts is following:
