| Abstract:According to the mature process technology and production experience in caustification section, by absorbing and digesting the advanced technology of while liquor clarify disk filter( CD filter) at home and abroad, and summing up the field application experience of various structural type CD filters, focusing on the research and development of the key components, overcoming the key technologies of double-layer air pressure seal ring type non-zone distribution valve, external cylinder type pneumatic back-blow pipe, trapezoidal hole type dynamic seal ring, head built-in outlet box compact cylinder, the third generation of YPL-III series new type CD filter was developed. The new type filter with a filtration area of 245 m2 was first put into operation in a large pulp and paper mill in Indonesia, the white liquor production was over 8000 m3/d, and clarity was no more than 23 mg/L, it has been running smoothly and stably. |
