Definitions

  • the invention relates to methods for wet treatment of laundry according to the preamble of claims 1 and 9. Furthermore, the invention relates to devices for wet treatment of laundry according to the preamble of claims 12 and 13th
  • treating liquid containing washing-active substances.
  • the treatment liquid which is not bound in the laundry, the so-called free liquor, separated from the laundry.
  • the treatment liquid then contains spent washing-active substances which have absorbed the dirt from the laundry items, but also unused washing-active substances.
  • the present invention seeks to provide methods and apparatus for wet treatment of laundry, which have over conventional methods and devices greater economy.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, spent washing-active substances are removed from the treatment liquid separated from the laundry. The spent washing-active substances bind the dirt that the treatment liquid has taken from the previous washing process. By removing the used washing-active substances, the dirt is thus at least for the most part removed from the treatment liquid. The treatment liquid with the remaining unused washing-active substances can then be reused for a subsequent washing process. As a result, unused washing-active substances are not lost and they also need not be neutralized for draining the treatment liquid into the sewage network. Above all, due to the method according to the invention, the fresh water consumption can be reduced, because the treatment liquid with the unused washing-active substances can be used again for washing the laundry items.
  • it is provided to remove spent wash-active substances from the treatment liquid separated from the laundry after washing and also from the treatment liquid separated from the dehydrator before rinsing.
  • This two-stage removal of the spent wash-active substances from the treatment liquid optimally provides spent washing-active substances with essentially only existing unused washing-active substances therein for a subsequent washing operation, in particular for a washing operation with a separate pre-wash and clear wash , Of the Fresh water requirement is thereby only a fraction of the treatment liquid required for the subsequent washing process, wherein, if necessary, only the actually used washing-active substances are to be replaced.
  • the spent wash-active substances are separated from the treatment liquid by filtration, preferably precision filtration. Since spent washing-active substances have a particle size that exceeds the particle size of unused washing-active substances due to the dirt pick-up, a separation between the unused and used washing-active substances can be carried out by filtration. Because the particle sizes differ only slightly, above all only in the micrometer range, precision filtration is particularly suitable for effectively removing at least a majority of the spent washing-active substances from the treatment liquid.
  • An advantageous development of the method provides for a prefiltration to be carried out before filtering out used washing-active substances from the treatment liquid.
  • This prefiltration eliminates large particles of dirt which, when subsequently filtering out used washing-active substances, in particular by means of precision filtration, can no longer have a disturbing effect by loading or even adding to the sensitive filters for precision filtration.
  • a particularly effective and reliable filtration of at least a majority of the smaller spent washing-active substances is possible.
  • the removal of spent washing-active substances from the treatment liquid is expediently carried out by micro- and / or ultrafiltration.
  • specifically used wash-active substances can be removed from the treatment liquid.
  • These are preferably particles with a size between 10 .mu.m and 0.005 .mu.m, preferably 1 .mu.m to 0.5 .mu.m. This is the typical particle size of spent washing-active substances, so that in this way at least a large part of the used washing-active substances is removed, but not the smaller unused washing-active substances.
  • Another method for the solution of the above-mentioned object comprises the measures of claim 9. Accordingly, it is provided, after the removal of spent washing-active substances from the treatment liquid to the content of the still contained in the same used washing-active substances determine. This can be done, for example, by a so-called bubble tensiometer, for example an H 2 O 2 sensor or a Cl_ sensor. Other measuring methods or sensors suitable for the particle size of unused washing-active substances are also possible.
  • a further embodiment of the method provides for comparing the measured content of the unused washing-active substances still present in the treatment liquid with a desired content of washing-active substances in the treatment liquid. If it is determined that the measured content of the unused washing-active substances still contained in the treatment liquid is below the desired content, fresh washing-active substances are added to the treatment liquid in a targeted manner. This replenishment takes place to such an extent that the treatment liquid again has a content of unused washing-active substances which corresponds to the nominal content of unused washing-active substances in the treatment liquid or is slightly higher, preferably in a specifically selected excess spectrum.
  • a rotating drum drivable having a washing machine, in particular continuous washing machine, and a drainage device, such as a dewatering press or a spin dryer, having apparatus for solving the above-mentioned problem has the features of claim 12. Accordingly, provision is made for each of a drain line for the treatment liquid fed back to the drum from the drum and to the drum for the discharge of the treatment liquid from the drainage device to be assigned a filter for removing spent washing-active substances from the treatment liquid. It is thus wherever there is not found in the laundry items used treatment liquid with both fresh and spent washing-active substances to filter out the used washing-active substances. As a result, both the treatment liquid discharged in the washing machine and the treatment liquid obtained in the region of the dewatering press are prepared for reuse.
  • the invention is thus particularly suitable for devices for washing, rinsing and dewatering of laundry items, wherein the rinsing takes place in the dewatering device.
  • At least one return line leading back to the beginning of the drum of treatment liquid from the drum is associated with a filter for removing spent washing-active substances from the treatment liquid. It can thus be the entire treatment liquid, which is obtained during the washing of the laundry items, freed of washed laundry substances before rinsing the laundry items.
  • treatment liquid is applied after prewashing and clear washing.
  • the spent washing-active substances are then removed from these separately obtained treatment liquids before the treatment liquid is used again for washing.
  • the treatment liquids which are at least largely freed of spent washing-active substances can be supplied to the laundry items before the pre-wash and / or before the final wash as required.
  • the higher-temperature treatment liquid from the previous clear-wash may be recycled after separating spent wash-active substances, while the treatment liquid from the pre-wash is returned to the pre-wash.
  • the respective treatment liquids no significant energy needs to be supplied in order to use them again.
  • the colder treatment liquid from the pre-wash need not be heated to be supplied to the clear wash.
  • filters are used for separating spent washing-active substances from the treatment liquid, which are designed as micro and / or ultrafilters.
  • filters are mainly membrane filter into consideration.
  • These membrane filters are preferably provided with support bodies, which may be ceramic support body.
  • the filters can be designed as so-called cross-flow filters or as dead-end filters.
