Title (EN) AUTONOMOUS VAPORIZATION STATION FOR CRYOGENIC FLUIDS
(FR) CENTRALE AUTONOME DE VAPORISATION DE FLUIDES CRYOGENIQUES
Abstract: front page image
(EN)Autonomous vaporization station allowing the transformation of cryogenic fluids from the liquid state to the gaseous state by reheating said fluids circulating into a nest of boiler-tubes immersed inside a tank. In a station comprising a heat generator, a tank, a reheating system for the water of the tank, an exchanger comprising one or several coiled tubes immersed into the tank and regulating and control means, the invention consists in the fact that the reheating water is constantly recycled through diffusion racks (54) and suction racks (56). The diffusion racks (54) consist of at least four perforated tubes located in the upper part of the tank (13). The suction racks (56) consist of two perforated tubes situated close to the bottom of the tank and connected to pumps which discharge the water to the generator. This recycling system of reheating water is controlled temperature-wise by an automatic regulator controlling a three-way valve which directs the water either to the boiler, or again to the tank (13), according to the recorded temperature and to the designed temperature.
(FR)Centrale autonome de vaporisation permettant de transformer des fluides cryogeniques de l"etat liquide a l"etat gazeux par rechauffage desdits fluides circulant dans un faisceau tubulaire immerge a l"interieur d"un bac. Dans une centrale comprenant un generateur de chaleur, un bac, un circuit de rechauffage de l"eau du bac, un echangeur comportant un ou plusieurs serpentins immerges dans le bac et des moyens de regulation et de controle, l"invention reside dans le fait que l"eau de rechauffage est constamment recyclee par l"intermediaire de rampes de diffusion (54) et de rampes d"aspiration (56). Les rampes de diffusion (54) sont constituees par au moins quatre tuyaux perfores occupant la partie superieure du bac (13). Les rampes d"aspiration (56) sont constituees par deux tuyaux perfores situes pres du fond du bac et reliees a des pompes qui refoulent l"eau au generateur. Ce circuit de recyclage de l"eau de rechauffage est controle en temperature par un autoregulateur commandant une vanne a trois voies qui oriente l"eau soit vers la chaudiere, soit de nouveau vers le bac (13), suivant la temperature constatee et en fonction de celle programmee.
