Abstract

The invention discloses a control method for large-scale preparation of phase change capsules based on microfluidics. The control method comprises the steps that the control system receives and analyzes signal data of a heating stirrer device, a micro liquid pump, a heating belt and a thermocouple thermodetector; the control system sends out a temperature adjusting signal, so that a core material solution and a wall material precursor solution flowing out of a container are always in a liquid state in the circulation process of the whole system, the flow of the core material solution, the wall material precursor solution and the mixed solution is adjusted by sending out a micro liquid pump power adjusting signal, so that the core material solution, the wall material precursor solution and the mixed solution stably flow out in a laminar flow state in a rear-section pipeline of a micro circulation pipeline, the core material solution is ensured to flow out in a droplet form in a core material micro channel circulation pipeline, the precursor in the wall material precursor solution is triggered to generate interfacial polymerization reaction on the surface of the core material by a triggering agent in the flown-out core material solution, a wall material is generated to wrap the core material, and thus, a capsule is formed; and finally, the prepared capsule is filtered and collected through a filter screen, and waste liquid is recycled.

Description

technical field [0001] The invention relates to the technical field of preparation of phase-change capsules, in particular to a control method for large-scale preparation of phase-change capsules based on microfluidics. [0002] technical background [0003] With the rapid development of society and economy and the depletion of non-renewable energy sources, the energy supply of human society is becoming increasingly tight. However, some renewable energy such as solar energy and wind energy cannot provide stable energy supply, and there is still a large amount of industrial waste heat in the industrial process. As an important means of energy storage, heat storage technology can be widely used in the fields of solar photothermal storage, industrial waste heat recovery and heat transfer fluid. There are several categories of heat storage including sensible heat storage and latent heat storage. Due to their high energy storage density and small heat storage volume, latent heat...
