Definitions

  • the invention relates to a method for adjusting the flow and temperature of washing 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 washing water in Counterflow is passed through these sinks, adjusting the flow and temperature of the wash water.
  • impurities such as superfluous chemicals
  • 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 inputting and dispensing the machine, such a sensor can be pressed onto the cloth.
  • the water flow and the water temperature can be set for a certain value of the desired washing effect.
  • 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 aim of the invention is to remedy the above-mentioned problems and to provide an improved method with which the optimally inexpensive setting of the flow 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 subdivided into three wash compartments 1 connected in series 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 on rolls through all compartments passed through.
  • the cloth run can be both vertical and horizontal.
  • the cloth is pressed by the press plant 4 and the water squeezed out returns to the washing water flowing through.
  • the wash water is heated and maintained for each wash basin, for example by blowing hot steam in.
  • a contamination concentration sensor such as a conductivity sensor, has been attached to the import and possibly to one of the wash basins and to the export, which is pressed onto the.
  • 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 and temperature that energy saving is made possible while maintaining the desired washing effect, for which purpose measures have been taken as shown in FIG. 2.
  • flow meters W and S have been arranged in the two main supply lines and temperature sensors T1 to T6, for example 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.
  • Conductivity sensors G1 to G3 have been installed to measure 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 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 proportionally to this concentration of the impurity.
  • the value of the desired conductivity according to n compartments together with the conductivity measured at import gives the desired washing effect ⁇ , this is the conductivity C n of the cloth when exported divided by the conductivity C o at import: ⁇ C n / C o .
  • the optimally inexpensive combination of water flow and temperature is calculated, after which it is set via the valves and adjusted in the event of deviations.
  • each washing compartment has the same washing effect with the same water flow and at the same temperature. Since this is not always the case in practice, for example as a result of the dimensions of the compartments and the pressing of the cloth between certain compartments, the average washing effect per compartment is used.
  • Figure 4 is a schematic representation of a wide washing machine with a number of i compartments given, into which the tissue 3 is inserted on the left and led out on the right and the contamination of this tissue decreases from left to right. The contamination increases in the wash water flow 2 from right to left.
  • C o ... C i-3 , C i-2 , C i-1 , C i is the impurity concentration of the cloth, and is K o ...
  • K i-3 , K i-2 , K i-1 , K i the concentration of the impurity in the wash water.
  • This figure shows that a certain desired washing effect can be achieved with a large number of water flow and temperature settings. To determine the optimal low-cost combination, the costs of steam and water with these settings must be known.
  • the amount of steam required to heat the wash water and the cloth includes the theoretically required amount of steam to keep the wash water and the cloth at temperature (linearly depending on the temperature) and the amount of steam required to compensate for the heat loss.
  • the corresponding desired exchange factor M and the corresponding temperature T can be calculated on the basis of an initial value and then incremental values of water flow in the flow area and the desired washing action. For this subsequent combinations of water flow and temperature, the corresponding costs are calculated and the combination with the minimum costs is selected. This combination of water flow and temperature is then set, all as indicated in the flow chart of Figure 9.
