Definitions

  • the invention relates to a new process for white water treatment of a paper machine.
  • the technical problem to be solved by the present invention is to overcome the existing drawbacks, and to provide a new process for white water treatment of a paper machine which improves the pulp yield and ensures the closed cycle of the white water of the paper machine.
  • a paper machine white water treatment process the collected white water of the paper machine is filtered by flocculation and inorganic membrane to obtain clear water, and then the felt is washed with water.
  • the flocculating agent in the step 1) is an inorganic flocculating agent.
  • the flocculating agent is modified diatomaceous earth.
  • 1 kg of flocculating agent per 1 ton of water is purified.
  • the flocculant has a mesh number of 300-350 mesh.
  • the inorganic film in the step 3) is fired from diatomaceous earth and has a filtration pore size of 5-30 um.
  • the process of the invention is used to completely solve the problem of reuse of the white water of the paper machine, and the water collected after the flocculation improves the pulp yield and ensures the closed cycle of the white water of the paper machine.
  • the main advantages are as follows:
  • the floor space is small, the system can be built in the papermaking workshop, saving one-time investment.
  • a white water treatment process for a paper machine includes the following steps:
  • the flocculant is an inorganic flocculant (modified diatomaceous earth), the dosage is 0.1%, and the mesh number is 300-350 mesh. The floc is recovered and the water is recycled to the collection tank.

Abstract

L'invention concerne un procédé de traitement de l'eau blanche d'une machine à papier, dans lequel l'eau blanche de machine à papier collectée est traitée par floculation et filtration sur membrane inorganique pour obtenir de l'eau propre ; et ensuite, l'eau propre est utilisée pour nettoyer un tissu de coton grossier. Le problème de la réutilisation de l'eau blanche de machine à papier est résolu par le procédé, et un cycle fermé de l'eau blanche de machine à papier est assuré.
