Summary of the invention
The purpose of this utility model provides the pretreated flocculation reaction equipment of a kind of sea water desaltination, and it is too complicated to solve present existing flocculation apparatus structure, the problem of the acute variation of water quality when being difficult to adapt to the seawater tide bulge and fall.
The utility model is achieved through the following technical solutions: the pretreated flocculation reaction equipment of a kind of sea water desaltination, comprise device framework, horizontal bar and turbulence plate, device framework and horizontal bar are affixed, and inner formation in the cavity is equipped with the polylith turbulence plate, and turbulence plate is perpendicular to the water (flow) direction setting; Have a plurality of apertures on the described turbulence plate.
As of the present utility model further preferred, described turbulence plate is divided into two kinds of self-adjustable turbulence plate and fixed turbulence plates, wherein, the two ends of self-adjustable turbulence plate and device framework flexible connection, two ends and the device framework of fixed turbulence plate are affixed.
Described fixed turbulence plate is positioned at the both sides of device framework, and the self-adjustable turbulence plate is positioned at the central authorities of device framework.
Adopt the positively effect of technique scheme: the utility model can be with the suspended impurity in the seawater and colloid and the abundant hybrid reaction of flocculation agent, form closely knit alumen ustum, by precipitating rear discharge purifying sea water and mud, purifying sea water carries out desalting by follow-up reverse osmosis process, compare with similar flocculation apparatus, have the following advantages:
1, processing efficiency is high, floor space is little
Adopt novel porousness turbulence plate, improved greatly flocculating effect, flocculation time shortens, and has therefore reduced equipment volume, saves flocculation sedimentation tank than traditional technology and takes up an area more than 60%;
2, strong shock resistance, applicable water quality are extensive
The porousness of turbulence plate promotes a large amount of generations of little whirlpool, add the adjustable-angle turbulence plate, make this technology strong shock resistance, when flow, raw water turbidity, some variation of dose, delivery turbidity is still stable, can be that aftertreatment becomes purifying sea water below the 2NTU through flocculation reaction deposition for the seawater of 50～100NTU with turbidity;
3, easy construction, duration of service is long
By optimization design, all parts in the flocculation apparatus be glass reinforced plastic and polypropylene material entirely, need not carbon steel part, seawater corrosion resistance, so that duration of service is more than 15 years, working life is long, and ratio of depreciation is invested in reduction;
4, water producing cost is low, remarkable in economical benefits
Owing to adopt novel mixing, conversion unit, save dosage more than 20% than traditional technology; Main body purifies part machinery-free transmission apparatus, saves a large amount of electricity charge; This technological operation is simple, can reduce managerial personnel, reduces the operational management expense.
