Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a novel micro fluid mixer, in particular to a mixer which utilizes the flowing kinetic energy of one phase with larger flow rate in the mixed multiphase fluid to form rotary flow when passing through a vortex generator by arranging the vortex generator, and in the rotary flow process, the mixed micro fluid is stirred in a rotary mode and then passes through a subsequent mixing unit to achieve the effect of fully mixing the micro fluid and the fluid with larger flow rate.
[ background of the invention ]
As is known, a mixer is an advanced, point-wise mixing plant unit. Compared with stirring type mixing equipment, the existing mixer is not provided with a moving part, the multiphase fluid is not mixed by a rotary stirring structure, but the fluid generates rotary motion when passing through the mixing unit by adopting an optimized design structure unit, so that the multiphase fluid generates the same effect as stirring in the rotating process, and the mixing purpose is achieved.
The mixing unit of the existing mixer is generally composed of a guide plate which is not parallel to the axis, multiphase fluid enters the mixing unit after simultaneously entering the same upstream pipeline, and the flow direction is constantly changed by rotating left and right in time when the multiphase fluid passes through the mixing unit, so that the middle fluid of the parallel flowing fluid in an ideal state is pushed to the periphery, and the peripheral fluid is also pushed to the middle, thereby achieving good mixing effect.
The existing mixer can be applied to mixing of liquid-liquid, liquid-gas, liquid-solid, gas-gas and other state media, and has better effect on fluids with different viscosity ranges, namely intermittent operation or continuous operation. However, the existing mixer is suitable for mixing media with large two-phase or multi-phase flow, and if a certain mixed medium exists in the mixed medium with small flow, the flow state of the trace medium does not change greatly along with other media during mixing because the proportion of the trace medium to the total mixed medium is small, so the mixing effect under the working conditions is poor.
[ summary of the invention ]
In order to solve the problems in the prior art, the invention provides a novel micro fluid mixer, and particularly relates to a novel micro fluid mixer which utilizes the flow kinetic energy of one phase with larger flow rate in a mixed multiphase fluid to form rotary flow when passing through a vortex generator by arranging the vortex generator, wherein the vortex generator and the mixed micro fluid are stirred in a rotating manner in the rotary flow process and then pass through a subsequent mixing unit to achieve the effect of fully mixing the micro fluid and the fluid with larger flow rate.
In order to achieve the purpose, the invention adopts the following structural scheme:
a novel micro-fluid mixer (see figure 1) comprises the following parts:
01-an upstream connecting tube; 02-a housing; 03-a flow guide pipe; 04-vortex generator; 05-a mixing unit; 06-downstream connecting pipe.
The invention has the following advantages:
1. the mixer provided by the invention adopts a special design concept, so that one phase with larger flow in a multi-phase mixed medium can be rotated by the vortex generator to generate a vortex before entering a conventional flow guide type mixing unit. The fluid which flows in a rotating way and the mixed micro fluid are stirred in a rotating way and then pass through the subsequent mixing unit. The mixer has good mixing effect on micro mixing working conditions with large flow difference.
2. In order to achieve a good mixing effect, the existing mixer equipment often needs to be provided with a plurality of continuous mixing units in series, and then the use effect can be achieved. The mixer adopts a special design concept, so that compared with the existing mixer, the mixer can greatly reduce the mixing unit, shorten the equipment size and reduce the capital investment on equipment devices.
3. Because the existing mixer equipment adopts a plurality of mixing units which are arranged in series, the whole pressure drop of the mixed fluid is large in the operation and use processes, and the continuous operation of the subsequent device is not facilitated. In order to ensure the operation of the subsequent device, a pressurization device is additionally arranged. The mixer disclosed by the invention is small in overall pressure drop, good in mixing effect, simple in overall structure, convenient to use and suitable for large-scale popularization and application.
