Disinfecting appts - with controlled evaporation of formaldehyde for disinfection and subsequently of ammonia for neutralisation of am

摘要

Liquid evaporation device operating at constant feed and discharge rates has at least one closed reservoir communicating at its lower part with a pipe with a slanting end resting in an evaporating tank contg. absorbent elements. Enables disinfectants such as formal and ammonia to be evaporated, to give vapour for disinfecting an article. Formaldehyde can be evaporated at a constant rate without polymerisation.
