Definitions

  • the invention relates to a method for adjusting the flow rate and temperature of wash water when washing out impurities, such as superfluous chemicals, from cloth webs in textile finishing processes using a wide-washing machine, in which a cloth web is passed through a number of wash basins connected in series and the warm wash water in counterflow Sink is led.
  • a method is known from practice.
  • the extent of the washout or the so-called wash effect can be controlled by means of contamination concentration sensors.
  • a contamination concentration sensor is, for example, a pH meter or a conductivity sensor that measures the extent of the conductivity of the cloth contaminated with excess chemicals.
  • a sensor When entering and dispensing the machine, such a sensor can be pressed onto the cloth.
  • the water flow rate and the water temperature can be set for a certain value of the desired washing action.
  • the thermal yield of the washing process is often not optimal.
  • the desired washing effect can namely be achieved in various ways, the extreme routes being: a) a lot of water and low temperature and b) little water and a high temperature.
  • too much wash water and too high temperatures are used, which leads to high energy costs.
  • the temperature rises (too high) the energy losses (and consequently the energy costs) increase exponentially, e.g. because the vaporization is much stronger at high temperature.
  • the invention aims to remedy the above-mentioned problems and to provide an improved method with which an optimally inexpensive adjustment of the flow rate and temperature of the washing water is achieved while maintaining the desired washing effect, which method can be used for all fabric qualities.
  • Fig. 1 shows schematically a wide washing machine, in which the unnecessary chemicals, such as alkali and reaction products, derived from lye and bleaching treatments, are rinsed out of the cloth.
  • a machine has, for example, three wash basins 5, each wash basin being divided into three wash compartments 1 connected in series in order to increase the washing effect.
  • the wash water 2 is passed through the machine in a countercurrent process, the fresh rinse water flowing into the machine on the right-hand side and then flowing through all the compartments.
  • the textile or cloth web 3 to be washed goes into the machine on the left-hand side and is guided on rolls through all compartments.
  • the cloth run can be both vertical and horizontal.
  • the cloth is pressed through the press plant 4. The pressed water is returned to the wash water flowing through it.
  • the wash water is brought up to temperature and maintained per wash basin, for example by blowing in hot steam.
  • a contamination concentration sensor such as a conductivity sensor, has been attached to the import and possibly to one of the sinks and to the outlet, which is pressed onto the cloth.
  • washing water consumption and temperature are generally selected so that a good rinsing or washing effect is obtained under all circumstances. This almost always means too much wash water and too high temperatures, which leads to high energy costs.
  • the invention now provides such a method for optimally coordinating the washing water flow rate and temperature, so that energy savings are made possible while maintaining the desired washing effect, for which purpose measures have been taken as shown in FIG.
  • Flow meters W and S are arranged in the two main supply lines for measuring the washing water and steam consumption, and temperature sensors T1 to T6, such as a Pt-100 element, have been installed in the individual wash basins for the temperature measurements.
  • a speedometer V for the speed of the cloth web has also been installed.
  • the valves in the wash water supply lines K1 to K6 can be designed as flow-controlled pneumatic valves.
  • the conductivity sensors G1 to G3 have been installed for the measurement of the contamination of the cloth during import, in one of the sinks and during export.
  • the control unit 8 shown in FIG. 3 can be a mini computer.
  • the measurement data of the temperature sensors T, the conductivity sensors G and the knives W, S, V are collected by a data logger 6, which forwards them once every ten seconds via an interface 7 of the control unit 8.
  • the control signals in binary code originating from this control unit are converted via an interface 9 into control signals of 4 to 20 mA for the valves generally indicated by 10. Proportional control is used for the water flow rate and PID control for the temperature.
  • the regulation takes place on the basis of the measurement of the concentration of the impurity in the cloth, for example by means of the conductivity, which corresponds to this concentration of the impurity in proportion.
  • the value of the desired conductivity after n compartments, together with the conductivity measured at the time of import, gives the desired washing effect ⁇ p, this is the conductivity C "of the cloth on export divided by the conductivity C o on import: ⁇ p C n / C o .
  • the optimally inexpensive combination of water flow rate and temperature is calculated, after which this is adjusted via the valves and adjusted in the event of deviations.
  • FIG. 4 shows a schematic representation of a wide washing machine with a number of compartments, into which the fabric is inserted on the left and out on the right and the contamination of this fabric decreases from left to right. The contamination increases from right to left in the wash water flow.
  • C o ... C l-3 , C 1-2 , C l-1 , C l is the impurity concentration of the cloth, and is K o ... K l-3 , R l-2 , K I - 1 , K, the concentration of the impurity in the wash water.
  • the exchange factor M for a washing compartment is defined as the fraction of the liquid coming in with the cloth, which is replaced by washing water.
  • the amount of steam required to heat the wash water and the cloth includes the theoretically required amount of steam to bring the wash water and the cloth up to temperature (linearly depending on the temperature) and the amount of steam required to compensate for the heat loss.
  • FIG. 6 shows that an optimally inexpensive combination of water flow rate and temperature can be found for each desired washing action.
  • the corresponding desired exchange factor M and the corresponding temperature T can be calculated starting from an initial value and then from incrementing values of the water flow rate in the flow area and the desired washing action.
  • the corresponding costs are calculated and the combination with the minimum costs is selected. This combination of water flow rate and temperature is then adjusted, all as indicated in the flow chart of Figure 9.
