Homodromous reverse spiral mixing device

Abstract

The invention discloses a homodromous reverse spiral mixing device.A plurality of spiral flow deflectors are arranged on the inner side of an outlet section of an internal fluid pipeline; and a plurality of reverse spiral outer flow deflectors of which the spiral direction are opposite to the spiral direction of the spiral flow deflectors are arranged on the outer side of the outlet section; when two kinds of fluid in the internal pipeline and an outer pipeline flow in the same direction, under the action of the spiral flow deflectors in the opposite directions, the inner fluid and the outer fluid have a large tangential speed difference at an approximately-annular intersection, then a plurality of slightly-inclined flow direction vortexes are formed, the flow direction vortexes entrain the inner fluid and the outer fluid nearby the flow direction vortexes together to intensively mix the inner fluid and the outer fluid, and the torque borne by the pipelines can be greatly reduced; the inner and outer fluids can also form spanwise vortexes by utilizing the speed difference in the axial direction, so that the mixing degree of the inner and outer fluids is increased; and the two kinds of vortexes interact with each other, and the two fluids are fully mixed through high-speed impact, violent friction, strong extrusion, tearing and crushing between the fluids, so that the mixing effect required by production or test can be met.

Description

technical field [0001] The invention belongs to the field of fluid technology, and in particular relates to a co-rotating and reverse-spiral mixing device. Background technique [0002] It is often encountered in industrial equipment or test equipment that two or more high-speed fluids need to be mixed quickly and uniformly in the shortest possible distance, but due to the inertia of the fluid itself and its high speed, two or more The mixing efficiency between the two fluids is low, and the mixing effect is not ideal, resulting in that the uniformity of fluid mixing within a limited distance does not meet the application requirements. Contents of the invention [0003] In view of this, the object of the present invention is to provide a co-rotating helical mixing device, which can realize efficient mixing of two or more fluids within a shorter distance and in a shorter time. [0004] A co-rotating spiral mixing device, comprising an external fluid pipeline (2) and an int...
