CYCLONE DESIGN & CONFIGURATION ( PRESSURE POWER GENERATOR)

CYCLONE DESIGN:-

The max^th tangential velocity according to kalen and zenz is given by Max U_T=22.6 gµ p_p (kb)^1.2 D^0.201/p²f(1-k_b)

We have to determine the cyclone diameter (D) by this equation

So, D^{0.201 =} U_T p²f(1-k_b)/22.6 gu Pp(kb)^1.2

We have been measured various parameter related to smoke particles

Exhaust volume =330 cm³

U_T = 7.7 m/s                                        = 49.203 ft/sec

g   = 9.81 m/s²                                                       = 32.2 ft/sec²

µ   = 8.9×10^-2 kg/m-hr                       = 16.61×10^-6 lbs /ft- sec

P_f   = 0.788 kg/m³at 175’c exhaust gas temperature.

     = 0.04919 lbs/ft³

P_p = 0.9 g/cc

      = 0.9×62.43 lbs/ft³ = 56.187lbs/ft³

Kb = 0.2

Substituting this value in above equation

D^0.201=49.2×(0.04919)²(1-0.2)/22.6×32.2×16.61×10^-6×56.187×(0.2)^1.2

          = 0.0952376×10⁶/98447.747

D^0.201 =0.9674

D      =0.4162 ft                           = 0.4162/3.2802 m

D      =0.125 m

D      =12.5 cm =130mm

CYCLONE DESIGN CONFIGURATION:-

For selecting high efficiency

Body diameter               D = 130 mm

Inlet pipe diameter        a = 3.80 cm

Inlet width                      b = 0.21 D = 5.25 cm

Outlet length                  S = 0.5 D = 12.5 cm

Outlet diameter             D_e = 0.4 D = 50 mm

Cylinder height              h = 1.4 D = 180 mm

Overall height                H =3.0 D = 325 mm

Dust outlet diameter     B = 0.4D     =52 mm

Cone height                    h_e = 145 mm

M.S sheet thickness           = 2mm (16 gauge)
