Switchable free/limited impinging stream mixer and use method thereof

Abstract

The invention discloses a switchable free / limited impinging stream mixer and a use method thereof. The switchable free / limited impinging stream mixer comprises a main body unit, a mixing unit and a connecting and fixing unit. The connecting and fixing unit comprises a joint A, a joint B and a fixed plate, wherein the joint A, the joint B and the fixed plate respectively penetrate through two channels of the center of the fixed plate. The mixing unit is of a quadrangular structure, the lower bottom surface of the mixing unit is provided with an annular convex edge, the convex edge is in nestedconnection with the main body unit, and the internal center of the mixing unit is provided with round stepped holes different in diameter. The main body unit is of a C-shaped structure. The main bodyunit is internally provided with an L-shaped channel and an I-shaped channel, the L-shaped channel penetrates through the sides and the bottom of the C-shaped structure, the tops of the I-shaped channel and the L-shaped channel are parallelly arranged, and the upper ends are all connected with the joints. The cavity in the C-shaped structure can contain the mixing unit. By changing a unit combination mode, switching of two free and limited mixing modes can be achieved, and regulation and control of micro-mixing performance of the mixer are achieved.

Description

technical field [0001] The invention relates to a switchable free / restricted impingement flow mixer and a use method thereof, which belong to the field of fluid micro-mixing process enhancement. Background technique [0002] Microscopic mixing is the premise of molecular reaction, and the use of process intensification technology is an important way to improve the effect of microscopic mixing. Common process intensification technologies mainly include technologies such as hypergravity, micro-flow, impinging flow, and static mixing. The use of these technologies can achieve high efficiency and integration of chemical processes. [0003] Supergravity is an important class of process intensification technology, and its core equipment is called rotating packed bed (RPB) or supergravity machine. Through the high-speed rotation of the packing bed, it can generate an acceleration far greater than that of the earth's gravity g In this force field, the fluid is cut into fluid micro...
