Description
Technical field
The utility model is related to a kind of boiler blowdown water recycling system, belongs to boiler affiliated facility technical field.
Background technology
Boiler blow-out system original design continuous blowdown flash tank can not meet requirement, then that sewer is not recovered and direct
Discharge, causes to waste the pollution with environment.Therefore, a kind of apparatus system of energy effective recycling boiler blowdown water need to be sought,
To realize the purpose for reclaiming water resource and energy-conservation.
The content of the invention
The purpose of this utility model is to provide a kind of boiler blowdown water recycling system, by determining to arrange and connecting boiler
Through a 16m after the sewer collection of row3Flash vessel flash distillation after isolate 180 DEG C, 1.0MPa steam after being depressured desuperheat, and
Enter 0.6MPa steam pipe systems；Liquid phase feeding condensate refining system after separation.Pass through above measure so that will arrange on the spot originally
The boiler blowdown water put is recycled, and has saved water resource and heat energy, protects environment.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of boiler blowdown water recycling system, including flash vessel（2）, flash vessel outlet vapor pressure-regulating valve（5）、
Liquid level adjusting valve（11）, safety valve（4）, Manual drain valve（3）, liquid level gauge（10）, pressure gauge（7）, thermometer（15）, its feature
It is the boiler blowdown water through collection（1）Through flash vessel（2）Decompression, cooling, the steam flashed off are adjusted after separation by pressure
Save valve（5）, check (non-return) valve（6）, reducing-and-cooling plant（8）After be incorporated to 0.6MPa steam pipe systems（9）, liquid phase is through Liquid level adjusting valve
（11）, check (non-return) valve（14）Send into condensate refining plant（12）.
In one embodiment of the present utility model, the flash vessel as described in right 1（2）, it is characterised in that also connect successively
Connect steam pressure regulating valve（5）, non-return valve（6）And reducing-and-cooling plant（8）.
In one embodiment of the present utility model, the flash vessel as described in right 1（2）, it is characterised in that top is connected
Safety valve, hand reducing pressure valve.
In one embodiment of the present utility model, it is characterised in that flash vessel（2）Outlet at bottom pipeline is sequentially connected liquid
Position regulating valve（11）And check (non-return) valve（14）.
In one embodiment of the present utility model, it is characterised in that（2）Bottom is provided with manual blowdown valve（13）.
The utility model is designed based on flash principle, by subtracting to the boiler blowdown water that original is discharged on the spot through flash vessel
After pressure, cooling, reach that the steam of vapor liquid equilibrium state sends into 0.6MPa steam pipe systems after separation, user uses for steam；Liquid phase
Condensate refining system is sent into after processing, condensate user is sent into.So as to realize the recycling of water resource, to energy-conservation, drop
Consumption, environmental protection are significant.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order that technological means of the present utility model, creation characteristic, reached purpose and effect are easy to understand, tie below
Close specific embodiment and the utility model is expanded on further.
As shown in figure 1, a kind of boiler blowdown water recycling system, including including flash vessel（2）, flash vessel outlet vapor
Pressure-regulating valve（5）, Liquid level adjusting valve（11）, safety valve（4）, Manual drain valve（3）, liquid level gauge（10）, pressure gauge（7）, temperature
Degree meter（15）, check (non-return) valve（6）, reducing-and-cooling plant（8）, 0.6MPa steam pipe systems（9）, check (non-return) valve（14）, manual blowdown valve
（13）.
Specific implementation process：Steam water interface from boiler periodical blowdown and continuous blowdown（Such as 9.8MPa, 320 DEG C,
Four boilers add up to 16.8t/h）Through pipeline 1 by lateral incision to delivering to flash vessel 2（Such as operating pressure 1.0MPa, operating temperature
180 DEG C, volume 16m3）, using flash principle, gas-liquid reaches balance, steam in flash vessel（Such as 180 DEG C, 1.0MPa）From expansion
Container top pipeline is by pressure-regulating valve door group（For example pressure is no more than normal value）, check (non-return) valve, and through reducing-and-cooling plant
Afterwards, 0.6MPa is sent into（E.g., from about 164 DEG C）Steam pipe system, for steam, user uses；Separated aqueous phase is adjusted through Liquid level
Valve group（For example ordinary water level should be at 1/2）, check (non-return) valve be sent to condensate refining system, after refined, for condensate
Family is used.To sum up, water resource and heat energy are fully recycled, reached by collection, flash distillation, gas-liquid separation by boiler blowdown water
Energy-conservation, consumption reduction, environmentally friendly purpose.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
