The invention relates to an efficient recycling production process of
obsolescence corrugated
cardboard (OCC) residue pulp, and belongs to the technical field of pulping and
papermaking production. The production process comprises the steps of collecting total gutter tailing, combining coarse screens in a coarse screening section, carrying out concentration, carrying out
grinding, carrying out mixing, carrying out
dilution, removing sand, carrying out fine screening, carrying out concentration, refining pulp, storing the pulp and conveying the pulp to a
paper machine. Through the addition of the combination of the coarse screens with re-crushing and screening functions in the screening section, sundries such as plastic, foam, gravels and the like are effectively prevented from blocking ordamaging disc mills, low-concentration sand removal devices, fine screening devices and the like used in the follow-up treatment process, and meanwhile, a high-power pulping
machine is additionally arranged, so that fibers in the
tailings are sufficiently defibered, ground and preliminarily separated and fibrillated. The daily tailing treatment amount is 500 t / d, the
recovery pulp yield is 400 t / d, and the
recovery rate reaches 80% which is greatly improved compared with the
recovery rate of 60% in a conventional recovery process. Therefore, OCC residue pulp is efficiently recovered by adopting the production process provided by the technical scheme, and important economic and environmental benefits are achieved.
