Description
Technical field
The utility model relates to a kind of industrial circulation water treatment systems, especially a kind of to be directed to industrial circulating cooling water system
The system that the blowdown water of generation is recycled belongs to the field of energy-saving technology of industrial circulating water system.
Background technique
Industrial circulating cooling water refers in the factory, is mainly used to condensed steam, the water of cooling product or equipment.Because
System requires water quality, so water source is generally from the more excellent municipal tap water of water quality or underground water etc..
Recirculating cooling water system enfeoffment enclosed and two kinds of open type again.Open type system be current most widely used, type most
A kind of more cooling systems.It is then to utilize hot water with the cooling heat removing processing medium or heat exchange equipment and being distributed of water
It is when directly being contacted with air that a part of hot water is evaporated, and after cooling down most of hot water, it is recycled.
In Open recirling cooling water system, since recirculated cooling water constantly evaporates in cyclic process and being concentrated causes
Water quality deterioration cannot reach cooling water quality standard, fresh water must be continuously replenished at this time and by the higher concentrated water of salt content
Discharge, makes the salt content in water maintain certain concentration, with Balance Water Quality.System is set by the water process producer of profession
Meter, construction and operation are concentrated according to supplement water water quality using medicaments control loop water such as acid adding, corrosion inhibiting and descaling agent, sodium hypochlorite
Multiplying power is at 4-6 times.
The evaporation capacity and rate of water make-up of recirculating cooling water system are designed by national standard, but in actual use, each
There is difference in enterprise, and enterprise can sum up the empirical data for meeting itself.General open type system evaporation capacity ≈ internal circulating load * 1%,
1.5-2 times of amount of makeup water=evaporation capacity, blowdown flow rate=rate of water make-up 25%-50%, such as internal circulating load are the system of 5000m3/H, are mended
Filled water amount is about 75-100m3/H, and displacement is about 19-50m3/H, this is a very big consumption, or even accounts for an enterprise
90% or more of total water consumption.
It if water discharging part can be recycled, can not only mitigate environmental pressure, for enterprise, will also generate sizable receipts
Benefit.
But relative to other waste water, recirculating water blowdown water has following notable feature:
1, high salinity.4-6 times that salt content is raw water can be released by concentration rate, if water inlet total dissolved solid TDS
For 200mg/L, then sewerage is 800-1200 mg/L, and conductivity is up to 1600-2400 μ S/cm.
2, easy fouling.Total hardness is and in a saturated state up to 800-1000 mg/L, by extraneous factor such as temperature, pH value
And after concentration influences, solid sediment matter is easily precipitated.
3, contain special agent.Such as slow-release scale inhibitor, antirust, anticorrosive agent, mud dispersing agent, fungicide.PH is generally
8-9, meta-alkalescence.
4, high suspended matter.Mainly by water microbe colony and secretion, silt, dust etc. constitute, turbidity >
15NTU, it is not easily settled under the influence of mud dispersing agent.
5, contain bacterium, algae and other microorganisms.Because dissolved with sufficient oxygen, suitable temperature and richness in recirculated water
The condition of supporting, is well suited for the growth and breeding of microorganism, under the inhibition of quantitative sterilization agent, reproduction speed is delayed.
Therefore, if to recycle to sewerage, the influence of above several factors must be excluded, is also contemplated that simultaneously
Land occupation, investment and operating cost.
Utility model content
