Abstract
PURPOSE: To recover NH3 efficiently with low heat loss and simple pipings, by introducing a refrigerant from a compressor into the cooling pipe of the NH3 gas recovery device of a dry type diazo copier, and directly cooling a recovering fluid and an NH3 containing gas with the refrigerant.
CONSTITUTION: NH3 containing gas 2 drawn from the developing chamber of a copier is cooled with refrigerant 12 in gas-liquid heat exchanger 11, and introduced into absorbing tower 1. NH3 recovering fluid 3 is cooled with refrigerant 12 in gas- liquid heat exchanger 12 and introduced into the upper part of tower 1. Gas 2 and fluid 3 are further cooled with pipe 7 for leading refrigerant 12 from exchanger 11, and the NH3 in gas 2 is almost thoroughly absorbed and stored in tank 6. Water is used for fluid 3, and "Flon R-12 or the like is used for refrigerant 12. Refriger ant 12 is recirculated with compressor 8 through expansion valve 9, heat exchangers 10, 11, and pipe 7.
