Definitions
- the first recycling reactor and the second recycling reactor are added to the reaction system, and the waste sodium chloride is recycled to generate sodium bicarbonate, which saves the cost;
- a micro-interface generator is installed in the secondary-use reactor, which increases the mass transfer area of the phase boundary between ammonia, carbon dioxide and sodium chloride solution, makes ammonia, carbon dioxide and sodium chloride solution fully contact, and improves the reaction efficiency , shorten the reaction time.
- the body is provided with an inlet communicating with the cavity, the opposite first and second ends of the cavity are open, wherein the cross-sectional area of the cavity is from the middle of the cavity to the first and second ends of the cavity.
- the second end is reduced; the secondary crushing piece is arranged at at least one of the first end and the second end of the cavity, a part of the secondary crushing piece is arranged in the cavity, and both ends of the secondary crushing piece and the cavity are open
- An annular channel is formed between the through holes of the micro-bubble generator.

Abstract
L'invention concerne un système réactionnel à micro-interface pour la préparation d'éthylèneglycol à l'aide d'un procédé au chloroéthanol, comprenant : un réacteur de matériau principal, un cristalliseur, un premier réacteur de recyclage et un deuxième réacteur de recyclage. Le réacteur de matériau principal est relié à un réservoir de stockage de bicarbonate de sodium et à un réservoir de stockage de chloroéthanol, le produit obtenu par une réaction dans le réacteur de matériau principal entre dans le cristalliseur et le cristalliseur est relié au premier réacteur de recyclage et au deuxième réacteur de recyclage. Un premier générateur à micro-interface d'ammoniac et un générateur à micro-interface de dioxyde de carbone sont disposés dans le premier réacteur de recyclage et un deuxième générateur à micro-interface d'ammoniac et un générateur à micro-interface à flux divisé sont disposés dans le deuxième réacteur de recyclage. Le premier réacteur de recyclage et le deuxième réacteur de recyclage sont reliés au réacteur de matériau principal pour renvoyer le bicarbonate de sodium résultant au réacteur de matériau principal. Le système réactionnel réduit les coûts du procédé de réaction et augmente l'efficacité de la réaction.
