See also Fig. 9 and Figure 10, Fig. 9 is the planar structure schematic diagram of second kind of embodiment of the utility model.Figure 10 is the A-A cross-sectional view of Fig. 9.Present embodiment is compared with embodiment illustrated in fig. 8, its general structure is identical, different is that this clarifier 21 also comprises a retainer plate 214, and the retainer plate 214 in the present embodiment is to be that the outer end of the metal spoke 213 that is made of 1.5 millimeters stainless steel alloy is also had laser welding method to be fixedly connected on the described metal retainer plate 214 with diameter.

See also Figure 11, Figure 11 is the planar structure schematic diagram of the third embodiment of the utility model.Embodiment illustrated in fig. 11 and embodiment illustrated in fig. 8 comparing, its general structure is identical, and different is that metal spoke 213 is prefabricated into U word shape 215, and the small end of U word shape 215 is used laser weld on described spider 212.

Alternate manners such as the laser weld in the utility model also can spot welding, riveted joint, casting connects or gluing replace.

Through test, the diameter of spoke 213 of the present utility model is preferably disposed between 0.3 to 5 millimeter, and the long-pending value of the radical of the diameter of spoke 213 and spoke 213 is preferably in more than or equal to 46 with smaller or equal in 460 the scope its clean-up effect the best.

The theory and the experimental basis of the spoke diameter in the utility model and the relation of spoke radical are as follows:

The basic function of this clarifier 21 is in motion process, with interception of the particle in the waste gas of the clarifier 21 of flowing through and separation, the efficient of the particle interception in 21 pairs of waste gas of the clarifier of rotation is exactly the spoke 213 of clarifier 21 and the particle collision probability K value in the waste gas.

And K=(tQ/tW) X100% (formula one)

In the formula one: tQ is the time (second) that waste gas passes through clarifier 21 spokes operation plane;

TW is that single spoke 213 is in the required time (second) of the angle of stroke between two adjacent spokes;

TQ=DW/UQ (second) (formula two)

In the formula two: DW is the diameter (millimeter) of spoke 213;

UQ is the flow velocity (mm/second) of waste gas

TW=r/UW (second) (formula three)

In the formula three: r is the arc length of the adjacent two spoke angles of clarifier 21; R=1/n (week), wherein n is the radical of the spoke 213 on the clarifier 21 same planes;

UW drives clarifier 21 motor rotating rotating speeds (cycle per second);

With formula two and formula three difference substitution formulas one, draw behind the abbreviation:

K＝(DW*n*UW)/UQ*100％

In the practical application, the rotating speed of drive clarifier 21 motor rotating commonly used has following three kinds, that is: 650 cycle per minutes (10.83 cycle per second); 1300 cycle per minutes (21.67 cycle per second); 2900 cycle per minutes (48.33 cycle per second).

Set the K value and be 1 (promptly 100%), when adopting motor speed to be 650 cycle per minutes (10.83 cycle per second), the flow velocity of waste gas is controlled in the scope of 500-5000 mm/second, and then the maximum of DW*n (being the product of spoke 213 diameters and its radical) is 461, and minimum of a value is 46; Similarly, when adopting motor speed to be 1300 cycle per minutes (21.67 cycle per second), the flow velocity of waste gas is controlled in the scope of 1000-10000 mm/second, then the maximum of DW*n (being the product of spoke 213 diameters and its radical) is 461, and minimum of a value is 46; When adopting motor speed to be 2900 cycle per minutes (48.33 cycle per second), the flow velocity of waste gas is controlled in the scope of 2200-15000 mm/second, the value of DW*n is also still in 46 to 461 scope.

Therefore, when the product of spoke 213 diameters and its radical is in 46 to 461 scope, the utlity model has best clean-up effect.
