The greasy dirt water filtration speed of the utility model should select economic filtering velocity, filtering layer is more, and filtering velocity can according to filtering layer number
It is faster, when selecting tank body internal drop index, suitable pressure drop index should be selected, filtering layer is more, and pressure drop is bigger according to filtering layer number.
As shown in Figure 6, Figure 7, two kinds of water-distributing device water distribution effect numerical simulation tank body section speed cloud atlas, in two kinds of devices
When treating capacity is identical, the existing water-distributing device filter cross-section sewage mean flow rate shown in application drawing 5 be only 0.15m/s (not
Add filtrate), speed component is uneven, and applies the water-distributing device filter cross-section sewage mean flow rate 0.31m/ of the utility model
S (not plus filtrate), VELOCITY DISTRIBUTION is more uniform, 2 times of about current water-distributing device, illustrates that the less generation of novel water distribution device is rapid
The nocuousness flow phenomenon such as stream, turbulent flow, takes full advantage of the centrifugation of multilayer filtrate, improves filter with multi-layer filter material grease point
From effect.
