Description
Technical field
Water treatment field is the utility model is related to, more particularly to a kind of open type cooling water chemicals dosing plant.
Background technology
Open type cooling water system is widely used in industrial production and civilian central air-conditioning facility, in day-to-day operation, meeting
Produce following quality problem：Burn into caused by ion concentration increase is concentrated by evaporation caused by oxygen and evaporation and concentration that the external world is brought into
Thus microbial reproduction caused by causing the pollution of fouling, suitable water temperature and the external world caused by hardness and basicity rise simultaneously causes
Microbiologic(al) corrosion etc., therefore daily dosing water process need to be implemented, include the control of cycles of concentration, anti-incrustation corrosion inhibitor, sterilization
Agent adds, wherein crucially to make medicament obtain it is enough, timely add, and as far as possible reduce manual operation into
This, improves the security of operation.
The existing many open type cooling water chemicals dosing plants of in the market, often there is following limitation in it：
1) liquid dosing pipe is directly connected to cool down on supply mains, because cooling water medicament such as anti-incrustation corrosion inhibitor is in often
Acidity, therefore during long-term dosing, cause the corrosion of the dosing access point locality on house steward and leakage problems occur, solve
Method can only be off the operating of cooling water system, and could repair mending-leakage after emptying the water in house steward, quite cumbersome and risk
Greatly.
2) be only equipped with metering drive device, realize mechanical dosing, but specific dosage how much, it is difficult to control, so only
The water analysis frequency can be increased, by continually detecting the concentration of medicament needed for cooling water, to calculate chemical feeding quantity, therefore dosing
With hysteresis quality, medicament can not be accurately and timely added.
3) be configured with colour comparatour in some chemicals dosing plants, can medicament needed for on-line determination concentration.But actual colour comparatour is easy
The interference of water turbidity is cooled, causes testing result to produce deviation；In addition, to use the medicament scheme specified, versatility compared with
Difference；And need to be equipped with online colour comparatour costly so that the purchase cost of whole chemicals dosing plant exponentially increases, and is unfavorable for
Popularization and application.
4) liquid feeding device is only equipped with, no solid medicating device, as solid chemicals need to be added, then can only be carried to cold
But artificial running cost and security risk are added directly toward adding in cooling pond after tower.
5) can only be hung without hanger device, it is necessary to when implementing lacing film (metal erosion test piece) monitoring in cooling pond, nothing
The corrosion tendency under streamflow regime in method simulation pipeline.
Therefore, it is necessary to develop a kind of open type cooling water chemicals dosing plant, can realize medicament it is accurate, add in time, avoid
Excessive dosing or dosing deficiency；Manual operation cost is effectively reduced, it is safe；And low manufacture cost, versatility is good, is easy to push away
Wide application.
