Description

Novel micro-fluid mixer

[ technical field ] A method for producing a semiconductor device

[ 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.

[ Utility model ] content

In order to solve the problem that exists among the background art, the utility model provides a novel trace fluid mixer, specific saying so one kind utilizes by the heterogeneous fluid of mixture, the great looks mobile kinetic energy of flow through setting up vortex generator, makes it form the rotatory flow when vortex generator, at the rotatory flow in-process, with by the rotatory stirring back of the trace fluid of mixing, pass through subsequent mixing unit again, reach the effect that makes trace fluid and great flow fluid intensive mixing.

In order to achieve the above purpose, the utility model adopts the following structure 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 utility model has the advantages of it is following:

1. the blender is owing to adopt special design theory, can make heterogeneous by the great looks of mixed medium flow, before getting into conventional water conservancy diversion type mixing unit, is rotatory by vortex generator earlier and produces the whirl. 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 blender compares with current blender owing to adopt special design theory, can reduce mixing unit by a wide margin, shortens equipment size, reduces the fund input on equipment device.

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 whole pressure drop of blender is little, mixes effectually, and overall structure is simple, and convenient to use is fit for popularization and application on a large scale.
