Description
Technical field
The utility model relates to a kind of descaling and antiscaling device of recirculating cooling water system, is specifically related to a kind of electrolyzing incrustation scale removal device.
Background technology
In industry and commercial hot water or cold water system, scale formation is very general and serious in the equipment such as interchanger, transport pipe and pump valve.The fouling meeting significantly increases the heat transfer resistance of exchanger tube wall, increases the running cost of system; Fouling also can cause the local corrosion of equipment, reduces its work-ing life; Also can blocking pipe when serious, reduce the actual internal area of water, increase flow resistance, increase system's transmitting power expense.Therefore the dirt that solves in the water system is prevented and treated problem, for safety in production, cut down the consumption of energy and the conserve water resource has very significant meaning.
Using mitigation and antiscaling technology comparatively widely at present, is to adopt the chemical scale-inhibiting technology that adds water quality stabilizer.But this method can only prevent incrustation scale in water system pipeline and heat exchanger surface deposition, and the place to go causes the incrustation ion of incrustation scale completely; But also have the personal management of needs, constantly chemical agent consumption has potential environmental hazard or the like shortcoming.

2H
2O+2e→2OH
-+H
2↑
Because reaction produces OH
-, make near the pH of cathode surface rise CO
3 2-Increase.
HCO
3 -+OH
-→H
2O+CO
3 2-
And Ca
2+, Mg
2+Move to the cathodic area owing to the effect meeting of electrostatic attraction Deng incrustation ion, and near the finally enrichment cathodic area, cause partial concn much larger than bulk solution concentration.This moment Ca
2+, Mg
2+Respectively with CO
3 2-And OH
-Reaction generates precipitation.
Ca
2++CO
3 2-→CaCO
3↓
Mg
2++2OH
-→Mg(OH)
2↓
This just makes the incrustation ion concentration in the water significantly reduce, and has played the inhibition incrustation scale in water system pipeline and the sedimentary effect of heat exchanger surface.And the incrustation scale of separating out in the cathodic area after brine electrolysis is handled is easy to be taken away by high velocity flow or with special-purpose removing equipment it is struck off.
