Title (EN) MECHANICAL SYSTEM FOR GENERATING MECHANICAL ENERGY FROM LIQUID NITROGEN, AND CORRESPONDING METHOD
(FR) SYSTÈME MÉCANIQUE DE PRODUCTION D'ÉNERGIE MÉCANIQUE À PARTIR D'AZOTE LIQUIDE, ET PROCÉDÉ CORRESPONDANT
Abstract:
(EN) The invention relates to a system for generating mechanical energy, comprising at least: a compressor; an expander; a heat exchanger; said system having a motor operative mode in which said system additionally comprises: means for the intake of pressurised liquid nitrogen in a liquid nitrogen intake inlet of said exchanger, means for the intake of air or gaseous nitrogen in an air or gaseous nitrogen intake inlet of said exchanger, means for discharging vaporised nitrogen at a vaporised nitrogen outlet of said exchanger, and means for discharging air or cooled nitrogen at another outlet of said exchanger for air or cooled gaseous nitrogen; means for the intake of said vaporised nitrogen into the interior of said expander in order to expand same; means for the intake of the air or cooled gaseous nitrogen into said compressor so as to produce compressed air or gaseous nitrogen therein; means for expanding said compressed air or gaseous nitrogen; means for heating the compressed air or gaseous nitrogen prior to intake into said expansion means or the interior of said expansion means; and means for recovering energy originating from the expansion of said vaporised nitrogen and the expansion of said compressed air or gaseous nitrogen.
(FR) L'invention concerne un système de production d'énergie mécanique comprenant au moins : un compresseur; un détendeur; un échangeur de chaleur; ledit système possédant un mode de fonctionnement moteur dans lequel ledit système comprend en outre : des moyens d'admission d'azote liquide sous pression dans une entrée d'admission d'azote liquide dudit échangeur, des moyens d'admission d'air ou d'azote gazeux dans une entrée d'admission d'air ou d'azote gazeux dudit échangeur, des moyens d'échappement d'azote vaporisé à une sortie d'azote vaporisé dudit échangeur et des moyens d'échappement d'air ou d'azote refroidi à une autre sortie d'air ou d'azote gazeux refroidi dudit échangeur; des moyens d'admission à l'intérieur dudit détendeur dudit azote vaporisé pour l'y détendre; des moyens d'admission dans ledit compresseur dudit air ou azote gazeux refroidi pour y produire de l'air ou azote gazeux comprimé; des moyens de détente dudit air ou azote gazeux comprimé; des moyens de réchauffage de l'air ou azote gazeux comprimé avant admission dans lesdits moyens de détente ou à l'intérieur desdits moyens de détente; des moyens de récupération d'énergie provenant de la détente dudit azote vaporisé et de la détente dudit air ou azote gazeux comprimé.
