Defrost device improving the operation of atmospheric vaporizers for liquefied gases

Abstract

Abstract 951,136. Revaporizing liquefied gas. AIR LIQUIDE S.A. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE. Sept. 29, 1961 [Oct. 12, 1960], No. 35325/61. Heading F4P. A method of defrosting the external surface area of an ambient air-heated evaporator for liquefied gas comprises continuously sweeping the surface to remove the frost as it is formed. The evaporator comprises a series of spacedparallel plates 2 to which are secured coils (not shown) through which flows the gas. Holders 11 carrying brushes 12 are fixed at their ends to endless chains 10 which are driven by a reduction unit 8; the brushes thus circulate in the spaces between the plates to remove frost forming on the latter. The plates are enclosed in a jacket, Fig. 1 (not shown), and atmospheric air is impelled between the plates by a fan, the delivery temperature of the gas being auto. matically regulated by movable flaps arranged to deflect from the plates a variable fraction of the air delivered by the fan.
