Description
Technical field
The present invention relates to water treatment field, particularly a kind of Recirculated cooling water treatment device.
Background technology
In nearly all chemical system and central air conditioner system, all with cooling water, heat exchange can be carried out. Enterprise generally adopts the water of river and lake of running water, fire water or processing after filtration as cooling water, certain density calcium magnesium plasma is often contained in these water, it enters in cooling tower cooling procedure in process heat exchange, because being accompanied by a large amount of moisture evaporations, calcium ion and magnesium ion in water are nearly all stayed in cooling water. Along with adding of supply water, the calcium ions and magnesium ions of considerable part is had again to be introduced in cooling pond. Go round and begin again, calcium ion and magnesium ion concentration in cooling water are raise, and then in its pipeline flowing through or equipment, separate out certain slightly solubility calcium carbonate and magnesium hydrate precipitate, the microorganism in cooling water system also adheres on tube wall or appts wall simultaneously. Precipitation and the attachment of these walls can reduce the heat exchange efficiency of heat exchanger, serious also can corrosion pipeline or by line clogging, and then cause danger.
Industrial general employing, to adding antisludging agent in cooling pond, prevents the phenomenon of in the process of heat exchange tube wall or appts wall generation Precipitation; General employing added certain density free chlorine to kill microorganism in cooling pond, protection pipe-line system. This interpolation behavior is often accompanied by industrial all processes always, and addition is huge, causes the rising of production cost.
