PURPOSE:To increase the velocity of a collision flow in each mixing chamber and to improve the mixing effect by making the cross-sectional area of a hole for discharging the liq. mixture to the outside larger than the cross-sectional area of a first small hole for surface collision in the title complex collision type liq. mixing method. CONSTITUTION:When liqs. are firstly mixed by surface collision and secondly by linear concentric collision, the cross-sectional area Z1 of the discharge hole 16 from a second mixing chamber 6 is made larger than the cross-sectional area A1 of the first small hole 4 for surface collision. Consequently, the pressure of the liq. Lm4 flowing in the discharge hole 16 is lowered, and the pressure in the mixing chamber 6 for linear concentric collision communicating with the hole 16 is also lowered. Accordingly, the velocities of the collision flows Lm1a and Lm1b flowing out into the mixing chamber 6 from the small holes 10 and 11 for linear concentric collision are further increased, and the liqs. are mixed by strong colliding force. In addition, the pressure drop of the small holes 10 and 11 for linear concentric collision is also reduced by the high-speed collision flow, and the pressure in the first mixing chamber 2 for surface collision communicating with the holes 10 and 11 is also lowered. Accordingly, the difference from the supply pressure into the mixing chamber 1 is increased, the velocity of the surface collision flow Lc3 flowing out from the surface collision small hole 4 is increased, and the mixing effect due to the surface collision is also enhanced. |
