Abstract
The invention discloses a method for circulating recycled paper production white water. According to the method, when closed circulation and a middle section white water solid content sediment effect are controlled well, influences by peculiar smell of white water on paper in a closed circulation process is removed by utilizing strong oxidation of ozone. Water balance is controlled well at the same time to guarantee stabilized operation of a closed circulation system. The method for circulating the recycled paper production white water has the advantages that the white water is used in a recycled mode, energy is saved, and quality and output of the paper are guaranteed.
Description
Technical field
The present invention relates to a kind of recycled writing paper and produce the method for plain boiled water circulation, be mainly used in the water requirement of paper industry, the recycled writing paper technological process of production and workshop section.
Background technology
At present, in paper technique, conventionally adopt recirculated water flow process, both waste water resources, the solid content in water and peculiar smell have obvious impact to the quality of paper, felt life-span on papermaking and the embossing problem of paper also have no small impact, because quality problem, rotten lumps roll banding cause paper broken end, affect the quality of paper, also make output be affected, large with hourly water consumption, disposal cost is high and can not qualified discharge.
Summary of the invention
The object of this invention is to provide a kind of recycled writing paper and produced the method for plain boiled water circulation.
Technical scheme of the present invention is: it be by: while controlling closed cycle well, the sedimentation effect of stage casing plain boiled water solid content; The impact of the peculiar smell that in solution closed circulation process, plain boiled water produces on paper quality; Carry out water balance, keep larger adjusting leeway, when meeting an urgent need pulping equipment fault, guarantee stage casing plain boiled water stable circulation; Set up felt sparge pipe Special circulation pond; Carry out sediment processed; Use the extraordinary felt of high drainability, guarantee felt service life and solve embossing problem; Use special intranet and extranet to solve the poor paper pulp network blocking sticky net phenomenon causing of water quality during closed circulation, guarantee that paper machine runs well, and makes the Quality and yield of paper unaffected; Resolve the paper broken end problem that rotten lumps roll banding causes; Closed cycle and the water balance of carrying out recycled writing paper plain boiled water are the keys of water saving, adopt the secondary circulatory system, the slurry dilution that is web part of paper machine adopts one-level circulation, and the plain boiled water namely getting off from wet end is directly used in slurry dilution net, and other workshop section's water adopts secondary to circulate.
Beneficial effect:
It is in the time controlling closed cycle well for the present invention, and when the plain boiled water solid content sedimentation effect of stage casing, the peculiar smell that utilizes ozone strong oxidizing to solve plain boiled water in closed cycle process affects paper.Carry out water balance simultaneously, guarantee closed circuit circulatory system stable operation.The advantage of technique of the present invention is that plain boiled water recycles, and saves the energy, guarantees again the Quality and yield of paper.
Accompanying drawing explanation:
Fig. 1 is process chart of the present invention.
The specific embodiment:
The present invention it be by: while controlling closed cycle well, the sedimentation effect of stage casing plain boiled water solid content; The impact of the peculiar smell that in solution closed circulation process, plain boiled water produces on paper quality; Carry out water balance, keep larger adjusting leeway, when meeting an urgent need pulping equipment fault, guarantee stage casing plain boiled water stable circulation; Set up felt sparge pipe Special circulation pond; Carry out sediment processed; Use the extraordinary felt of high drainability, guarantee felt service life and solve embossing problem; Use special intranet and extranet to solve the poor paper pulp network blocking sticky net phenomenon causing of water quality during closed circulation, guarantee that paper machine runs well, and makes the Quality and yield of paper unaffected; Resolve the paper broken end problem that rotten lumps roll banding causes; Closed cycle and the water balance of carrying out recycled writing paper plain boiled water are the keys of water saving, adopt the secondary circulatory system, the slurry dilution that is web part of paper machine adopts one-level circulation, and the plain boiled water namely getting off from wet end is directly used in slurry dilution net, and other workshop section's water adopts secondary to circulate.
