Process for cleaning the waste gas from drying processes using heated gas
摘要:
The waste gas accumulating in the drying of products containing volatile ingredients is cooled, the condensate obtained is subjected to crossflow membrane filtration and part of the cleaned waste gas is returned to the drying process. The concentrate obtained is put to a material, thermal or other use. The both effective and economic process is suitable for eliminating the aerosols, particularly the organic aerosols, present in the waste gas.
