Abstract
There is provided a microdevice in which a plurality of fluids L1, L2 and L3 are caused to pass through respective fluid supply passages and flow together in one mixing reaction flow path, and the fluids are diffused in the normal direction of the contact interface thereof while being allowed to flow as a thin layer shaped laminar flow, by which mixing or reaction is carried out. The fluid supply passages are of a concentric multiple cylindrical construction to concentrically laminate the fluids L1, L2 and L3 joined together in the mixing reaction flow path, and the opening width near a joining point of the fluids is reduced to contract the flow.
Claims21
A microdevice apparatus which manufactures materials and products by mixing or reaction of fluids in the fields of chemical industry and pharmaceutical industry, the microdevice comprising:
- an outer tubular member;
- a central member having an end;
- a mixing reaction flow path disposed between the outer tubular member and the central member;
- and
- a plurality of fluid supply passages which are positioned concentrically around the central member, in which a plurality of fluids are caused to pass respectively through the fluid supply passages and thereafter flow together in the mixing reaction flow path, the mixing reaction flow path being bound by a surface of said outer tubular member and a surface of said central member,
- wherein at least one of said surface of said outer tubular member and said surface of said central member has a tapered portion, such that a width of the mixing reaction flow path is reduced to contract the flow,
- wherein a temperature control device is provided to control a mixing temperature or a reaction temperature of the fluid flowing in said mixing reaction flow path;
- and
- wherein said surface of said outer tubular member and said surface of said central member are parallel downstream of said tapered portion.
A microdevice comprising:
- an outer tubular member;
- a central member having an end, said central member including a hollow portion which extends in a longitudinal direction of said central member, said hollow portion housing a heat medium supply pipe which delivers a heating medium to the hollow portion;
- a mixing reaction flow path disposed between the outer tubular member and the central member;
- and
- a plurality of fluid supply passages which are positioned concentrically around the central member, in which a plurality of fluids are caused to pass respectively through the fluid supply passages and thereafter flow together in the mixing reaction flow path, the mixing reaction flow path being bound by a surface of said outer tubular member and a surface of said central member,
- wherein at least one of said surface of said outer tubular member and said surface of said central member has a tapered portion, such that a width of the mixing reaction flow path is reduced to contract the flow.
