Claims (2)

1. Способ извлечения ртути из ртутных ламп и изделий, содержащих ртуть или пары ртути, включающий разгерметизацию лампы либо изделия, содержащего ртуть, и сбор ртути в специальном резервуаре, отличающийся тем, что перед разгерметизацией лампу либо изделие, содержащее ртуть, охлаждают течение 1-3 мин до температуры, лежащей ниже температуры кристаллизации ртути по шкале Кельвина Т, определяемой для давления паров ртути р в атмосферах из выражения Т=Тпар/(1-0,2 lg(p)), где Тпар - температура парообразования ртути при нормальном давлении ро=1 атмосфера, при этом процесс сбора ртути производят в течение не более 0,5 мин после разгерметизации.1. A method of extracting mercury from mercury lamps and articles containing mercury or mercury vapor, comprising depressurizing a lamp or article containing mercury, and collecting mercury in a special tank, characterized in that before depressurization, a lamp or article containing mercury is cooled for 1- 3 min to a temperature below the crystallization temperature of mercury according to the Kelvin scale T, determined for the vapor pressure of mercury p in atmospheres from the expression T = Tpar / (1-0.2 lg (p)), where Tpar is the temperature of vaporization of mercury at normal pressure po = 1 atmosphere and, the mercury collection process is maintained for no more than 0.5 minutes after depressurization. 2. Способ извлечения ртути из ртутных ламп и изделий, содержащих ртуть или пары ртути по п.1, отличающийся тем, что перед разгерметизацией охлаждение лампы либо изделия, содержащего ртуть, осуществляют в жидком азоте.2. The method for extracting mercury from mercury lamps and articles containing mercury or mercury vapor according to claim 1, characterized in that before depressurization, the cooling of the lamp or article containing mercury is carried out in liquid nitrogen.
