METHOD AND APPARATUS FOR PRODUCING SLUSH NITROGEN |
摘要 |
<p>A method for producing slush nitrogen comprises the steps of: spraying liquid nitrogen from a nozzle into a vessel kept under a reduced pressure with a nozzle diameter and a spraying pressure being so adjusted as for the liquid nitrogen to maintain the form of droplets, to thereby form liquid nitrogen fine particles having a uniform particle diameter and disperse said particles in the vessel; vaporizing nitrogen from the droplet particles during the stay thereof in the space of the vessel, to solidify liquid nitrogen particles by vaporization latent heat and form fine solid nitrogen particles having a uniform particle diameter; and mixing the solid nitrogen particles with liquid nitrogen.</p> |
