Description
Technical field
The utility model relates to the boiler applications technical field, particularly relates to a kind of boiler blow-out system that can carry out continuous blowdown and periodical blowdown.
Background technology
In the existing oil of China, chemical industry, iron and steel, power station, medicine, printing and dyeing, city heat supply and other all multiple enterprises, all at a large amount of use boilers, due to the continuous evaporation and concentration of pot water, the impurity content in residue water can be more and more higher.For reducing the content of salt, alkali in pot water, must discharge frequently the sewage after a part concentrates from pot water, can reduce a pot water salt content by blowdown, avoid occurring priming, guarantee quality and the steam quality of pot water.When boiler water level is too high, also can reduce water level by blowdown.In boiler blowdown water, except containing a small amount of salt, incrustation scale, silt and other sediment, the overwhelming majority is the demineralized water that contains amount of heat, and it is recycled, and can make the industry energy conservation consumption reduction, increases benefit.
China is most steam generator systems of operation at present, are provided with continuous blowdown and periodical blowdown, and most flow setting is that the blowdown condensed water is directly entered sewerage, seldom consider or do not consider at all the recycling of this part water.Wherein, periodical blowdown normally adopts atmospheric flashing, and the steam that tank deck flashes off directly enters atmosphere, and the condensed water at the bottom of tank (comprising a large amount of recirculated cooling waters that is used for cooling) enters trench nearby.
As shown in Figure 1, existing technological process is described as:
One, the continuous blowdown liquid from boiler tangentially enters the continuous blowdown tank, carries out flash distillation in tank, realizes the vapour-liquid separation.The steam vapour system that the low-pressure steam that the tank body top flashes off enters full device recycles, the lime set of tank base by the first Liquid level adjusting valve LV1 adjust flux after the reasonable liquid level of tank (control continuous blowdown) enter boiler periodical blowdown tank.
