Mini mixer capable of uniform mixing gas mixture rapidly, and preparation method

Abstract

The invention publishes a micro mixer which can uniform mix gas fast and its preparation method, it involves the gas-mixing area of technology, it has joined the raised ridge in the original miniature T mixer's hybrid channel, the height of the raised ridge is consistent with the depth of the hybrid channel, the raised keel's width is half as large as hybrid channel, and the length is consistent with the width. The raised ridge distributes dividable along the both sides of the mixed channel, there has been a raised ridge's width between the neighboring raised ridge, and arranges separately. The number of the raised ridge lies on the hybrid channel's length, n= (l-3) / 2l1, n expresses the raised ridge's integer, l expresses hybrid channel's length, l1 is the raised keel's length of side. The design advantages of the invention is: join the raised ridge after the hybrid channel may cause the two gases to be pressed when they flow through the raised ridge to reduce the distances between them, it can help to mix the diffusion; and because the speed increases when the gas flow through the raised ridge, it can easily produce the eddy current and increase the two contacted areas, and it is also good to mix the gases; in addition, it may produce backflow near the downstream of the raised ridge, and strengthens the two gas mixed performance.

Description

technical field

[0001] The invention relates to the technical field of gas mixing, in particular to a micro-mixer capable of rapidly and uniformly mixing gas and a preparation method thereof. Background technique

[0002] Since the 1990s, with the rapid development of nanomaterials and microelectromechanical systems, a lot of research has been done in the field of small-scale and fast processes. The micro-hybrid device is an important executive device in the micro-chemical industry, which has the characteristics of high efficiency, fast response time, and less reagent consumption. So predecessors have done a lot of research on it.

[0003] Micro-mixers are generally divided into two types: active and passive. Active mixers have an external disturbance source, while passive mixers generally only need a pressure source to cause fluid flow, and can achieve rapid mixing without an external power source. The most studied passive mixer in the world is the micro-T mixer. It is fo...
