Definitions

  • the present invention relates to a production method fresh wiping solution, containing at least 90% of water and additives, and treating this wiping solution used by the inks of one or multiple intaglio printing machines operating in closed circuit and a device for the implementation of this process.
  • the printing plates mounted on the plate cylinder in which the designs are engraved, are wiped by the friction of a wiping cylinder turning in the same direction as the plate cylinder and which removes the ink outside the sizes of the plate.
  • a wiping cylinder turning in the same direction as the plate cylinder and which removes the ink outside the sizes of the plate.
  • the part bottom of it is in a tank wiping, this tank being further equipped with brushes and squeegees.
  • a system of nozzles spurts from the fresh wiping solution on the wiping cylinder and the fresh solution when mixed with the ink goes exit the wiping tank as used solution.
  • US patent 5,390,598 describes a such as permanent cylinder cleaning system wiping in an intaglio printing machine.
  • wiping solutions is described in patent DE 1,546,776 and consists of an aqueous solution containing 1 to 5% by weight of alkaline detergent, 2 to 10% by weight of a commercial cleaning product. containing alkaline phosphate and 1 to 10% by weight of a wetting agent. More particularly, this aqueous solution contains 1.5 to 2.5% by weight of caustic soda NaOH, 2 to 5% by weight of sodium phosphate Na 3 (PO 4 ) and 1 to 3% by weight of castor oil sulfonated.
  • the recycling capacity of this process after ultrafiltration is around 80%, this value additionally dependent on the quality of the ink used and of its concentration in the wiping solution.
  • the object of the present invention is to provide a closed circuit process, in particular in which most of the water and flocculation products in circuit is recovered from the used wiping solution, reused to produce the fresh wiping solution and no longer rejected at taste. Consumption of water and flocculation of the process can thus be strongly decreased and we will only get waste solids which can then be treated with respect environmental protection standards.
  • the invention also makes it possible to no longer use coal active that corrected the chemical oxygen demand.
  • Such a method of producing wiping solution fresh and used wiping solution treatment is defined by the steps of claims 1 and 2.
  • Independent claim 9 defines a device for implementing the method according to the invention.
  • Claims 10 to 18 define modes of particular realization of the setting device process work.
  • Figure 1 is the block diagram of a method of wiping solution treatment known in the state of the technique.
  • FIG. 2 is the block diagram of a method of production and recycling of the wiping solution according to the invention.
  • Figure 3 is the block diagram of a setting device implementing the method according to the invention.
  • the wiping solution may optionally contain more detergent.
  • the wiping solution fresh is produced by mixing water, caustic soda and sulfonated castor oil.
  • the fresh solution is introduced into one or more wiping tanks in step (b) of the process and contaminated with the inks.
  • the used wiping solution is then transferred from the wiping tank (s) to the ultrafiltration installation to undergo step (c) of the process, namely ultrafiltration.
  • This step (c) produces on the one hand a clear solution which is without further recycled as a fresh wiping solution in step (d), and on the other hand a concentrated residual solution containing ink.
  • This ultrafiltration step makes it possible to recover approximately 80% of the solution.
  • the concentrated residual solution then undergoes step (e) of the process which is flocculation. This flocculation occurs by adding calcium chloride CaCl 2 and ferric chloride FeCl 3 .
  • step (f) of the process The result of the flocculation is then filtered in step (f) of the process, and solid residues and a filtered solution are thus obtained.
  • this filtered solution is neutralized by adding hydrochloric acid HCL.
  • the neutralized solution undergoes in stage (h) an evaporation which gives on the one hand distilled water, and on the other a concentrated saline solution.
  • the distilled water is collected in order to use it to produce fresh wiping solution in step (i) of the process, while the concentrated salt solution is filtered in step (j) and this filtration gives d on one side of the solid salts and on the other a solution highly concentrated in salt which is reused to carry out the flocculation of step (e) of the process.
  • Distilled water is sent to a tank where it is mixed with softened water taken from the city network. This mixture is finally used to produce fresh wiping solution by adding sulphonated castor oil and caustic soda NaOH, in the proportions indicated above for example
  • Figure 3 shows an example of a device for implementation of the process which is the subject of the invention.
  • This device comprises a tank 1 into which the spent solution passes and is transferred into a first ultrafiltration tank 2, from which it then passes into a first ultrafiltration unit 3.
  • the clear solution from this first ultrafiltration unit 3 is brought into a tank of fresh solution 21 from where it is reused as a fresh wiping solution, while the concentrated residual solution from this first ultrafiltration unit 3 is sent to a second ultrafiltration tank 4 and there in a second ultrafiltration unit 5.
  • the clear solution from this second ultrafiltration unit 5 is in turn sent to the fresh solution tank 21 to be reused as a fresh wiping solution, while the concentrated residual solution is brought into a concentrated solution tank 6.
  • This concentrated residual solution then passes into the flocculation 7 where the flocculation step is carried out.
  • Means for adding the calcium chloride CaCl 2 and the ferric chloride FeCl 3 necessary for flocculation are mounted on the flocculation tank 7. These means comprise at least one reservoir and a metering pump for each compound added.
  • the flocculated solution is then brought into a filter press 8 separating the solid residues from the solution.
  • the filtered residual solution is stored in a filtered solution tank 9.
  • This solution is then brought into a neutralization tank 10 where it is neutralized by the addition of hydrochloric acid HCL and recovered in a neutralized solution tank 11.
  • means for adding hydrochloric acid are mounted on the neutralization tank 10. These means comprise at least one tank and a metering pump.
  • the solution is sent to a first evaporation unit 12.
  • the water vapor obtained from this first evaporation unit 12 is recovered in a tank of distilled water 17, while the solution salt passes into a salt solution tank 13 then into a second evaporation unit 14.
  • the water vapor obtained from this second evaporation unit 14 is also recovered in the distilled water tank while the salt solution and concentrate passes into a tank 15 and then into a filtration system 16 from which one side extracts solid salts and the other a solution which is recycled by suitable means, such as for example a pump, in the flocculation tank 7
  • suitable means such as for example a pump
  • the water is sent to a water tank 19, which also receives city water once it has passed through a water softener 18, and the water softened and the distilled water are sent to the wiping solution mixture tank 20 where the fresh solution is prepared by adding sulphonated castor oil and caustic soda. This is finally transported in the fresh solution tank 21 and again passes through the wiping tank or tanks of the printing machines after use.
  • the modes of execution described are given for example and variations as part of the claimed protection are possible.
  • the proportion of the components of the wiping solution may be slightly varied.
  • the acid used to perform neutralization can be acid sulfuric.
