The invention disclsoes an energy-saving
rosin processing method, and belongs to the technical field of production of
rosin. The method comprises: crushing and washing
rosin particles; putting the rosin particles into a melting pot for melting; putting melted rosin liquid into a high-level pot and a clarifying pot for clarifying; putting the clarified rosin liquid into a pre-heating rosin storage pot for pre-heating; putting the pre-heated rosin into a
continuous distillation pot for distilling, wherein heat for pre-heating the rosin liquid before melting and
distillation is obtained from high-temperature
tail gas and oil gas, which are released through
distillation, and heat needed by distilling comprises steam from a boiler,
superheated steam from a
heating furnace and heat which is absorbed and raised through a
heat pump. By adopting the energy-saving rosin
processing method, the high-temperature
tail gas and the oil gas in the
distillation pot are recycled, and the
heat pump, namely a heat raising device, is arranged in a distillation process, so that the heat of surrounding air in a
processing process is sufficiently utilized; when the
heat pump is used, hot
air temperature needed by the boiler and the
heating furnace is also reduced, so that fuel consumed by the boiler and the
heating furnace is reduced, and the aim of saving energy is realized.
