Title:
DOUBLE FLUID NOZZLE AND DEVICE FOR FREEZING AND DRYING LIQUID WITH LIVING SUBSTANCE
Document Type and Number:
Japanese Patent JP3594751
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To atomize a liquid to be atomized widely in response to characteristic of the liquid to be atomized or a particle diameter range of automation by a method wherein a second injection hole is arranged at an outer circumference flow of a first injection hole and a circulating means for making a circulating of each of gas and liquid is arranged at forward portions of these first and second injection holes.
SOLUTION: A liquid feeding hole 10b of slight fine diameter subsequent to a liquid feeding hole 104 of a base section 103 is formed and an extremity end of an intermediate section 102 of the base section 103 forms an extremity end head part 101 of which diameter is expanded. A first injection hole 107 for injecting liquid inside the extremity end head 101 is formed. Then, an annular vortex flow chamber 110 is formed at an outer circumference of the first liquid injection hole 107 and a forward part of the vortex flow chamber 110 is communicated with a second injection hole 111 of narrow clearance for injecting annular gas. Forward portions of these first and second injection holes 107 and 111 and provided with whirling means 108 and 117 for making each of whirling flows of gas and liquid. With such an arrangement as above, it becomes possible to perform an atomization under a moderate condition.
