The invention provides a method for wax recovery, including the following steps: dewaxing procedure, among, waxy fabric is transferred through case for washing waxes with wax-soluble organic solvent to generate wax-bearing solution by dewaxing; steam recovery procedure, among, wax-bearing solution is transferred into retort to form organic solvent vapour and liquid wax by distilling, which are condensed to liquid state later and then transferred into said case for washing waxes. The ratio of wax recovery in said invention could be enhanced to 100%. Besides, the invention also provides devices for wax recovery.
