The selection of the utility model cleaner diameter D is decided according to the settling region surface load, and surface load is 4-7m
2H).Centrifugal separating area is an inside and outside sleeve formula structure, and inner core is a pressure type eddy flow centrifugal separating area, the outer gravity type boat davit eddy flow centrifugal separating area of urceolus.The separating factor a relation of centrifugal force and gravity, a=r n are all satisfied in centrifugation in the inner/outer tube
In the formula: α-separating factor;
R-rotation radius (m);
N-rotating speed (r/min);
A enough just can satisfy separating effect greatly as can be seen.
1, centrifugal separating area explanation:
The water inlet pipe flow velocity is v
Inner diameter of steel flue
1Inner diameter of steel flue, mm; Q flooding velocity L/s)
The sealing of inner core top, center drilling, opening diameter d
The inner core length L
The urceolus diameter should guarantee that upflow velocity is v
The urceolus upper end is open, and the upper end exceeds inner core 100-200mm;
The inner/outer tube lower end is 45 ° of tubaeform expansions mouths, and tubaeform length is 100-200mm;
Urceolus and inner core lower end discrepancy in elevation l
Inner core lower port diameter D
1+ 100tg45 °;
Urceolus lower port diameter D
2+ 150tg45 °;
2, sloping plate deposition district explanation
Sloping plate deposition district swash plate is a polypropylene material, the thick 2mm of swash plate, swash plate spacing 100mm, 60 ° at inclination angle, straight side length 1000mm.
3, self-stip filtrating area explanation
The self-stip filtrating area is that stainless steel filtering net is joined the self-stip nozzle structure.Filter screen becomes tubular construction, and sewage inside enters, the outside outflow.The filter screen aperture is generally 0.15-0.2mm, and the filter cylinder diameter determines that according to the flow size crossing water flow velocity is 20-30mm/S.
4, example explanation
Certain case history, water yield Q=50m
3/ h, water inlet concentration of suspension 5000-10000mg/L; The cleaner water inlet is equipped with a certain amount of conventional flocculation agent and coagulant aids, and handling back water outlet concentration of suspension is 10-20mg/L, removes the self-stip water, and producing water ratio is 95-98%.
The key part size:
Cleaner diameter D=2800mm;
Centrifugal separating area inner diameter of steel flue D
1=250mm, length L
Centrifugal separating area urceolus diameter D
2=600mm, urceolus length overall 1500mm;
Opening diameter d on the centrifugal separating area inner core
The water outlet baffle plate is 90 ° of cones, following bore 700mm;
Self-stip cartridge filter diameter 450mm, tube length 1500mm, perforate precision 0.2mm;
Hang brush drive unit power 0.55KW.
This cleaner is to suspended substance removal efficient height in the water, and with interior sewage, the suspended substance removal rate can reach 99.2%--99.5% to concentration of suspension 10000mg/L, and concentration of suspension is less than 10mg/L (every liter of milligram) in the general water outlet.Efficiently solving high suspended matter concentration causes the dirt in swash plate district stifled.Because filtrating area adopts self-stip to filter, and has significantly reduced the backwash energy consumption.
