Problems solved by technology

[0005] Traditional micro-mixing equipment requires the use of laser engraving, electrical discharge machining, and electrochemical etching. Therefore, the production cost of the equipment is high, and it is difficult to manufacture large-scale micro-mixing equipment. It is often only used in small mixing and reaction systems such as pharmaceuticals and fine chemicals.

specific Embodiment 1

[0035] A micro-hybrid device based on a planar multi-channel ceramic element with a structure such as figure 2 shown.

[0036] Wherein, the flat multi-channel ceramic element is a porous alumina material. The manufacturing steps of the ceramic element are as follows:

[0037] 1. Mix 4 kg of alumina powder with a median particle size of 20 μm and 0.2 kg of firing aids evenly;

[0038] 2. Add 300 g of methyl cellulose, 150 g of glycerin, 15 g of oleic acid, 150 g of vacuum mineral oil and 900 g of water, and through the steps of mixing, mud refining, aging, etc., to obtain plastic mud;

[0039] 3. Use an extruder to extrude the mud into a flat multi-channel green body;

[0040] 4. The green body is dried by microwave radiation;

[0041]5. The dried green body is heated up to 400°C at a speed of 2°C / min and kept for 1 hour, and then heated to 1400°C at a speed of 2°C / min for 2 hours, and then cooled with the furnace.

[0042] After the fired ceramic product is cut, it is ob...

specific Embodiment 2

[0047] A micro-mixing device based on a flat multi-channel ceramic element, the basic structure of which is similar to the specific example 1, except that the micro-mixing device includes 10 ceramic elements 2 arranged in parallel.

Abstract

The invention discloses a micromixer for fluid materials. The micromixer comprises the main components of a multichannel thin-walled micropore ceramic element, a container housing, a sealing part and the like. Two fluid materials flow inside from internal channels and an external space of the multichannel thin-walled micropore ceramic element, wherein one material enters a space of the other material through a ceramic thin wall and is mixed with the other material. The multichannel thin-walled micropore ceramic element can be produced through a low-cost process, the size and shape ranges of the micropore ceramic element are wide, a micro-device or a large device can be conveniently fabricated, the requirements of different process scales are met, and the micromixer can be applied to multiple industries of chemical engineering, pharmacy, foods, environmental protection and the like.

Description

technical field [0001] The invention relates to the fields of inorganic non-metallic materials, chemical industry, pharmacy, food and environmental protection, and in particular to the manufacture of a micro-mixing device and its application in a fluid mixing process.
