- Such a method and such a device are - as explained in more detail below with reference to FIG. 1 - known from practice.
- a disinfectant and bleaching active oxygen-containing washing aid is used and the press water loaded with this washing aid is at least partially dewatered Parts of the press water that are fed back into the winding stage can be mixed with the recycled process water from the winding stage the prewash stage can be used again.
- a peracetic acid solution is used as a washing aid.
- a special water supply to the prewash stage is necessary in order to rule out in this method that protein-containing impurities present in the washware denatured by the press water returned to the prewash stage are no longer washable or can only be washed out with difficulty.
- At the beginning of each wash cycle only fresh water and only press and / or rinse water which is returned in the middle of the cycle are initially supplied.
- the invention has for its object to carry out a generic method and to design a countercurrent washing system so that the hygienic and aesthetic requirements placed on the treatment of the laundry are permanently maintained.
- this object is achieved according to the invention in that the process water at the end of the rinsing stage and / or in the post-treatment stage, a bactericidal and fungistatic, active oxygen-free washing aid is metered in to a sufficient extent and the metered amount of the washing aid is determined and is preferably documented and that at least in the process water of the post-treatment stage a concentration of 0.03 ml / 1 process water to 0.17 ml / l Process water of this washing aid is continuously maintained by appropriate metering.
- the invention creates a method which enables safe disinfection of the circulating water created by re-used process water and the avoidance of surface contamination.
- the cycle water created by returning the press and aftertreatment water to the rinsing stage is thereby safely disinfected.
- the invention ensures that the rinsing stage / post-treatment stage / dewatering stage cycle water is always free of germs that could cause hospital infections. This safety is achieved in that the metered amount of bactericidal and fungistatic, active oxygen-free washing aid is determined - that is, monitored - and preferably documented and continuously maintained.
- a very safe process is created, both with regard to the washing and the disinfection effect, which ensures permanent compliance with the hygienic and aesthetic requirements placed on the laundry at the end of the washing process.
- the size of the content of washing aids in the process water which has a significant influence on the quality of the washing process, is constantly monitored in the area of the aftertreatment stage or the dewatering stage, and is preferably documented and kept at the desired concentration by metering in washing aids.
- a bactericidal and fungistatic detergent is used as a washing aid. This guarantees hygienically perfect conditions for the items to be washed at the end of the washing process. In particular, this prevents the recontamination of the laundry, the formation of mold stains and the formation of odors when the laundry is stored in a moist condition.
- the amount of rinsing water can optionally be dispensed with, so that the method according to the invention then enables washing without disturbing oxygen concentrations which cause denaturation of protein and thus difficult or, under normal washing conditions, difficult washing out of protein compounds, for example blood.
- the method according to the invention does not cause any more than the fiber damage to the items to be washed, which in itself cannot be avoided by the washing process.
- Comparative experiments with comparative fabrics which were subjected to washing processes by the process according to the invention and, in comparison, to normal washing processes with the addition of washing aids containing active oxygen at the end of the rinsing stage and / or in the post-treatment stage and without returning post-treatment and press water to the rinsing stage show no differences in the loss of tensile strength and in the damage factor of the laundry.
- the invention provides that the metered amount of washing aids is related to the amount of aftertreatment and press water returned to the rinsing step from the aftertreatment step and the dewatering step in such a way that, taking into account the amount carried off with the laundry, into the aftertreatment step Process water ingredients set the concentration values in the process water in this area.
- the amount of bactericidal and fungistatic, active oxygen-free washing auxiliary agent to be added to the aftertreatment stage can be reduced in order to set a concentration of 0.03 ml / l - 0.17 ml / l in the aftertreatment stage.
- the invention sees a configuration for avoiding an undesirably high salting-out of the Process water that the salt concentration in the process water at the end of the rinsing stage or in the area of the aftertreatment stage or the dewatering stage is determined and preferably documented and a salt concentration in the process water less than 1200 mg / l, preferably less than or equal to 1000 mg / l process water, by metering in fresh water the last chamber of the rinse stage and / or the post-treatment stage is continuously maintained.
- the further quantity that significantly influences the quality of the washing process namely the salt concentration in the process water, at the end of the rinsing stage or in the area of the aftertreatment stage or the dewatering stage is continuously monitored and preferably documented and by metering in fresh water with a low salt content kept constantly in the range of the desired concentration. This prevents excessive salting of the process water.
- the metered amount of fresh water is related to the amount of post-treatment and press water returned from the post-treatment stage and the dewatering stage to the process water, taking into account the process water carried over into the treatment stage with the laundry in this area set the salt concentration values mentioned in the process water, as provided by the invention in an embodiment. In this way, the amount of fresh water to be metered in can be reduced to a minimum.
- deviating salt concentrations are only counteracted by changing the fresh water metering if compliance with the specified return amount of aftertreatment and press water into the rinsing stage has previously been established.
- the shutdown of the system can also be indicated optically and / or acoustically, which the invention also provides. It is of particular advantage in the process according to the invention that the total consumption of washing aids and fresh water can be reduced compared to processes without recirculation of aftertreatment and press water by means of the aftertreatment and press water recycling, in conjunction with the constant monitoring of the desired concentration ranges of washing aids and salt content. Therefore, the method according to the invention is further characterized in a further embodiment in that the total consumption per kg of dry water in fresh water and disinfectant detergent is at most the same as operation without recycling post-treatment and press water to the rinsing stage, and the total consumption of detergent and fresh water is preferred is lowered. With the method according to the invention, the amount of fresh water to be supplied to the washing process can be reduced by up to 50% compared to a washing process without aftertreatment and press water return.
- a bactericidal and fungistatic, active oxygen-free washing aid in an amount of 0.2 - 1 ml / kg, preferably 0.6 ml / kg, dry wash or 0.03 ml / l to 0.17 ml / l, preferably 0.1 ml / l, metering in process water, as the invention provides in a further development.
- washing oxygen in particular a peracetic acid solution
- washing oxygen in particular a peracetic acid solution
- the invention provides in a further development that a washing aid containing active oxygen is metered in in the washing stage and the process water of the washing stage is removed from the washing line at the beginning of the washing stage.
- the object is achieved in that at least in one of the areas rinsing stage, aftertreatment stage and dewatering stage with collecting tank at least one sensor from the group of sensors for determining salt concentration in the process water and in the return line leading to the rinsing stage for the aftertreatment and press water a device for setting and / or measuring the returned amount of aftertreatment and press water is installed and that the flow monitoring device, the at least one sensor and the device are connected in a line and effective manner to a control unit which measures the flow rates and the saiz concentration is determined and, depending on these values, taking into account the process water constituents carried over into the post-treatment stage with the laundry, the fresh water supply and the metering of the washing aid controls in such a way that the desired concentrations of detergent and the salt content are set in the aftertreatment stage.
- the invention creates a device which permanently ensures compliance with the hygienic and aesthetic requirements placed on the items to be washed at the end of the washing process.
- the variables that significantly influence the quality of the washing process namely the content of washing aids and the salt concentration in the process water, are constantly monitored in the area of the aftertreatment stage or the dewatering stage and are preferably documented and are constantly in the range of the desired by metering in washing aids and / or fresh water with a low salt content Concentrations kept.
- a bactericidal and fungistatic, active oxygen-free washing aid is used as the washing aid.
- the device is designed in such a way that a flow rate measurement is integrated in the return line for returning aftertreatment and press water into the rinsing stage and that the flow rate monitoring device for metering in the washing aid is a flow meter, in particular based on inductive flow measurement, or an oval gear meter.
- control unit documents the recorded values, as a result of which the entire device meets the requirements of the guidelines for hospital hygiene and infection prevention for the laundry operation when returning press water to the rinsing stage.
- Figure 1 shows a process and plant scheme according to the prior art
- FIG. 2 is a process and device scheme according to the present invention.
- FIG. 3 is a process and plant diagram of a second embodiment according to the invention.
- a washing line with twelve chambers 1-12 and a filling funnel 13 and a downstream dewatering press EW as well as pipelines with shut-off and deflection elements, addition devices for water FW, washing and washing aids PESa, PESb, as well as containers T2 and T3 for collecting or temporarily storing process water.
- the chambers 1 and 2 are assigned to the prewash zone VW, 3-7 to the rinse or wash zone KW, 8-11 to the rinse zone SP and 12 to the aftertreatment zone NB.
- the press water PW of the dewatering stage EW and the after-treatment water NW from the after-treatment stage NB are collected in the tank T3 and the rinsing water SW from the rinsing stage SP is collected in the tank T2.
- the laundry is placed in the first prewash chamber 1 via the hopper 13 and after the end of the respective treatment from chamber to chamber until finally the aftertreatment NB such as, for. B. starches, fabric softening, neutralizing and / or disinfecting and conveyed from there into the dewatering press EW. (When the first, middle or last chamber is mentioned, these terms refer to the conveying direction of the laundry).
- a partial amount in the example 2.5-4 l / kg TW, is fed to the last washing chamber 7, which flows against the laundry to the first washing chamber 3, where it is drawn off and disposed of in the channel K as waste water.
- the other subset of the flushing water SW from the tank T2 is fed to the hopper 13 during washing and pre-washing of the laundry.
- fresh water FW in an amount of 3 to 4 l / kg TW (FWb) is fed to the filling funnel 13 at the beginning of the cycle of a wash cycle for washing the items to be washed into the prewash stage VW.
- the fleet level at the middle of the cycle is increased with 2.5 - 6 l / kg TW of recycling or circulating water from tank T2. From there it flows with the laundry in the same direction for wetting / soaking and prewashing via chamber 1 into chamber 2, from which it is drawn off and disposed of as waste water.
- Peracetic acid solution PESa is used in an amount of 1.73 to 3 ml / kg TW partly in chamber 11 and / or partly in chamber 12.
- the part used in chamber 12 after it became effective in the aftertreatment NB, enters the chamber 11 of the rinsing stage with the reused treatment (NW) and press water PW.
- the predominant part of peracetic acid PESa can be added in chamber 12, since the still effective part of the peracetic acid in the re-used water NW and PW can be effective over the entire rinsing stage.
- the measurement and control systems according to the invention are shown in the layout diagrams in FIGS. 2 and 3.
- the process diagram shown in FIG. 3, in which the re-used post-treatment (NW) and press water PW is added approximately in the middle of the rinsing zone SP (chamber 9), has the advantage that the recirculated water NW and PW are used in one chamber in which the laundry has a higher temperature and therefore the post-treatment (NW) and press water PW is better for cooling down of the laundry. Otherwise the diagrams of Figures 2 and 3 do not differ.
- the washing line process water in the chamber 12 of the aftertreatment stage NB is supplied with a bactericidal and fungistatic, active oxygen-free washing aid BAFU in a quantity of 0.2-1 ml / kg, preferably 0, via a metering line 18. 6 ml / kg, dry laundry added TW.
- the washing aid can also be fed to the last chamber 11 of the rinsing stage SP, which is not shown here.
- the bactericidal and fungistatic detergent is added to the aftertreatment step in such an amount that a concentration of 0.03 ml / l to 0.17 ml / l process water is established in the process water of the standing bath of the aftertreatment step NB.
- a flow monitoring device 19 for the washing aid is arranged in the metering line 18.
- the flow monitoring device 19 can be a flow rate measuring device or an oval gear meter, in particular one that works on the basis of inductive flow measurement.
- the flow monitoring device 19 is used to set and control the metered amount of washing aid. Usually, 0.2-1 ml / kg TW of bactericidal and fungistatic, active oxygen-free washing aid are metered in to adjust the desired concentration of washing aid in the process water of the post-treatment stage NB.
- the flow monitoring device 19 is operatively connected to a control unit 17 via a first electrical line 20, so that after corresponding conversion into an electrical signal, the values for the flow rate of washing aids detected by the flow monitoring device 19 are transmitted to the control unit 17.
- a measuring probe 14 for determining the salinity in the collected aftertreatment (NW) and press water PW is installed in the tank T3. Alternatively, this probe could also be installed in chamber 12.
- a very advantageous method for measuring the salinity is the inductive measurement of the conductivity of the process water.
- the conductivity is a measure of the electrolyte content of the liquor and thus represents the content of soluble salts. By comparison measurement it is possible to assign a certain conductivity to a certain salinity.
- the sensor or the measuring probe 14 is likewise connected to the control unit 17 via a second electrical line 21.
- a return line 22 leads from the tank T3 into the chamber 11 (FIG. 2) or the chamber 9 (FIG. 3) of the rinsing stage.
- the aftertreatment (NW) and press water PW are returned to the rinsing stage through the return line 22.
- a device 15 for setting and / or measuring the returned aftertreatment (NW) and press water quantity is installed in the return line 22. This is preferably a flow meter.
- This device 15 for setting and / or measuring the amount of circulating water returned from the aftertreatment and dewatering stage is also connected to the control unit 17 by a third electrical line 23.
- the metered amount of washing aid is thus determined by the flow monitoring device 19, the salt concentration of the aftertreatment and press water which can be recycled as circulating water is determined by the sensor 14, and the amount of aftertreatment and press water returned to the rinsing stage is determined by the device 15 and by means of the respective electrical lines 20, 21 and 23 are transmitted to the control unit 17 as an electrical signal corresponding to the respective measured value.
- These signals are recorded in the control unit 17, the corresponding corresponding measured values are documented and processed for controlling and regulating the washing process.
- the control unit 17 also takes into account the specifications set by the operating personnel, which are a measure of the reproduce the process water ingredients carried over to the post-treatment stage NB.
- the amount of washing aid added with the flow monitoring device 19 is adjusted so that a concentration of 0.03 ml / l to 0.17 ml / l of bactericidal and fungistatic, active oxygen-free washing aid is obtained in the process water of the aftertreatment stage NB. If the control unit now recognizes on the basis of the transmitted data that the current metering setting leads to a permanent undershoot of the desired concentration of washing aids in the process water, the washing line automatically shuts it down.
- the length of time that the lower - or also the upper - limit value is undershot can be set by the operating personnel, for example in minutes or cycle times of the car wash. In the event of such a permanent undershooting of the limit value, it is likely that there is a device fault without which the quality of the washing process cannot be guaranteed.
- the operating personnel use the control unit 17 to specify an optimal salt content, in the example less than or equal to 1000 mg / l of process water. If the salinity rises above this value, the probable cause for this is an insufficient fresh water supply. However, it may also be because the ratio of the fresh water fed to the rinsing stage SP to the returned amount of aftertreatment water NW and press water PW is unfavorable, for example that the press water and aftertreatment water proportion becomes too high. Among others therefore, a flow measurement 15 is installed in line 22 for returning the water NW and PW to the rinsing stage SP.
- Control unit 17 processes a signal that opens or opens a control valve 16 connected to control unit 17 via a fourth electrical line 24.
- This valve 16 opens or regulates the inflow of fresh water FWa to the rinse stage SP, which in this case leads to an increase in the amount of fresh water added to the chamber 11.
- a limit switch is also recommended for the salinity.
- Is z. B a salinity of 1200 mg / l process water permanently, that is, for a longer period than specified, exceeded, this also leads to a shutdown of the system via the central control system 17, so that a system error responsible for this can be eliminated.
- the aftertreatment (NW) and press water PW is held in the chamber 9 of the rinsing stage SP only for reasons mentioned above, as in FIG. 2, introduced into the chamber 11.
- the return amount of aftertreatment (NW) and press water PW determined with the aid of the flow measuring device 15 is also used in the control unit 17 to control and adjust the amount of washing aids to be metered in with the flow monitoring device 19.
- the control unit 17 controls the flow monitoring device 19 in such a way that the desired concentration of 0.03 ml / l to 0.17 ml / l of washing aids is set in the process water of the post-treatment stage NB, taking into account the washing aid returned with the amount of aftertreatment and press water returned.
- the fresh water line 25 leading to the valve 16 and from there to the chamber 11 of the rinsing stage SP can have a branch line 26, shown partly in broken lines, through which fresh water FWb can also be fed to the filling funnel 13.
- bactericidal and fungistatic, active oxygen-free washing aids are used exclusively, it is not necessary to add fresh water (FWb) to the filling funnel 13 despite the return of rinsing and / or press water (from tank T2) to the filling funnel, since this washing aid does not contain any active oxygen a denaturation of protein-containing impurities present in the laundry could cause. This is different if - as shown in the exemplary embodiments according to FIGS. 2 and 3 - active oxygen-containing peracetic acid solution (PESb) is added as a further washing aid in the washing stage KW.
- PESb active oxygen-containing peracetic acid solution
- Active oxygen then enters the process water of the washing stage and this process water containing active oxygen or this washing liquor is partially transferred with the laundry from chamber 7 into chamber 8 during the transition from washing stage KW to rinsing stage SP.
- This washing liquor is discharged from the chamber 8 into the tank 2 and can then - as is known from the prior art - be fed back into the filling funnel 13.
- circulating water containing active oxygen gets into the filling funnel and, as explained above with regard to the prior art, must be diluted there with fresh water.
- a fresh water supply FWb into the filling funnel 13 by means of the branch line 26 is necessary.
- a didecyldimethylammonium chloride containing disinfectant is used, as is known, for example, under the name Sekural fongi.
