Definitions

  • the invention relates to a method and a device for regulating the steam supply in a damper housing according to the preamble of claim 1 and of claim 4.
  • a control is required which in each case supplies the damper housing with so much steam that the temperature in the damper required for an optimal reaction remains constant and that the damper housing is completely filled with steam and if possible has no air pockets.
  • the best way to achieve this is to maintain a constant vapor pressure in the damper housing that is above atmospheric pressure.
  • This object is achieved according to the invention with a method with the features of claim 1 and with a device with the features of claim 3.
  • the invention is based on the physical fact that media with different temperatures layer according to their density.
  • the hot and thus lighter water vapor fills the damper housing from top to bottom and displaces the heavier air.
  • This property is used in an optimally simple manner by the method according to the invention or by the device to determine the pressure inside the damper or the degree of steam filling by measuring the temperature. Since the temperature is measured in the area of the lowest vapor layer, an optimal degree of filling can always be maintained. A sharp drop in temperature can be measured in the border area between the lowest and therefore heaviest vapor layer and the ambient air, so that the lower vapor level can be determined with the temperature measurement.
  • the measurement is particularly reliable and simple if the temperature outside the damper housing is measured in a pipeline that communicates freely with the steam atmosphere in the steam housing and with the outside atmosphere.
  • the measurement of the temperature in the pipeline outside the damper housing also has the advantage that the stratification in the pipeline is more constant than at other points within the damper housing.
  • the separation point between hot steam and colder ambient air remains unaffected by operational turbulence at a constant level under optimal conditions. In this way, no complicated measuring devices are required inside the damper housing.
  • the steam can flow freely through the pipeline into the outside atmosphere, so that the temperature at the measuring point only increases when steam flows past the measuring point instead of the displaced air.
  • the degree of filling can be controlled in an optimally simple manner if, when the temperature at the measuring point drops, steam is supplied to the damper housing until the temperature at the measuring point rises again.
  • a complete filling of the damper housing with steam is ensured in that the pipeline extends under the damper housing and that the temperature sensor is arranged below the damper housing.
  • the steam only reaches the temperature sensor when the entire damper housing is filled with steam and when a layer of steam builds up in the pipeline.
  • the pipeline can have a straight section which has a plurality of connection points for a temperature sensor which are arranged at a distance from one another.
  • the temperature sensor can be placed at various points on the Pipeline to be attached. It would also be conceivable to attach more than one temperature sensor to the pipeline in order to achieve more precise control or an increased safety factor.
  • the government-controlled means have a steam regulating valve in a steam feed line leading to the damper housing, the steam regulating valve being operable by a controller which compares the temperature measured at the temperature sensor with a target temperature which corresponds to a damper housing completely filled with steam.
  • This temperature can be determined by measurements, the measured value also allowing conclusions to be drawn about the temperature or the pressure at any point in the damper housing.
  • the steam atmosphere is influenced by alternative controller-controlled means. For example, fresh water can also be injected into the damper housing when a heating device in the damper housing is actuated at the same time.
  • a damper 8 is shown in a highly simplified representation, as is usually used for the treatment of a fabric web 2 in a steam atmosphere.
  • the fabric web 2 comes from a pretreatment system, not shown, through the inlet channel 9 into the damper housing 1 and is guided in a meandering manner through the damper via lower guide rollers 10 and upper guide rollers 11 in a bound web guide.
  • the damper housing 1 is covered with an insulation 12.
  • the inlet opening 19 on the inlet channel 9 is kept as narrow as possible in order to prevent steam from escaping as far as possible. Touching the fabric web 2 e.g. A flexible lip seal is not permitted at this point, otherwise the liquid carried along by the fabric web, e.g. Dyes, bleaches, etc. would be scraped off.
  • the fabric web 2 leaves the damper housing 1 via a water lock 13, in which a deflection roller 18 is arranged.
  • the water lock prevents steam from escaping through the outlet.
  • an outlet opening can also be formed, which is designed like the inlet opening 19.
  • the fabric web is then a post-treatment machine such as fed to a washing machine.
  • steam is supplied to the damper housing from a steam source (not shown) in a steam feed line.
  • the steam arrives in a collecting line 20 and from there via several steam distribution pipes 14 into the interior of the damper housing.
  • a steam control valve 16 is arranged in the steam feed line 15 and is equipped with a pneumatic, hydraulic or electromotive actuator.
  • the steam control valve 16 is controlled by a controller 17 and opens or cuts off the steam supply in the damper housing, depending on the actual state determined. As a rule, the damper is heated by means of saturated steam.
  • the pipeline 3 is arranged on the side of the damper housing and extends below the bottom of the damper housing.
  • the stratification in the damper housing corresponding to the vapor density can thus continue in the pipeline, since it is open to the outside atmosphere at one end.
  • a temperature sensor 4 is arranged on the pipeline 3, which feeds the measured temperature to the controller 17 via a measuring transducer, not shown in any more detail.
  • the desired setpoint temperature is set on controller 17 when the damper is started up.
  • FIG 2 an advantageous embodiment of the pipeline 3 is shown in more detail.
  • the pipeline is fastened to the side wall 21 of the damper housing 1 with a connecting flange 5.
  • the pipeline could also extend straight down from the bottom of the damper housing.
  • condensate would also flow out, which is undesirable on the one hand and which on the other hand could falsify the measurement results.
  • a lateral arrangement at a certain distance from the floor is therefore more advantageous.
  • From the connecting flange 5, the pipeline extends vertically downward over a bend 23.
  • the outlet opening 22 is therefore in any case below the deepest point of the damper housing 1.
  • the diameter of the pipeline 3 is dimensioned such that the steam atmosphere can propagate in layers in an unhindered manner.
  • the temperature sensor 4 is fastened to a connecting eye 7 and projects obliquely from above into the interior of the pipeline 3.
  • the temperature determined can be read directly on a thermometer 6.
  • a plurality of connection eyes 7 can be arranged at regular intervals on the straight section of the pipeline, into which a temperature sensor 4 or a sealing pin can be inserted as required. As a rule, however, the optimal position of the sensor 4 on the pipeline 3 is determined by tests, so that only a single connecting eye 7 is required.
  • a control sensor 24 can be arranged, which measures the actual temperature in the working area of the damper housing. This temperature can be read on the control thermometer 25.
  • the stratification of a steam column 26 with increasing density or decreasing temperature from top to bottom is relative to the pipeline 3 in FIG. 2 represented symbolically.
  • the steam column 26 or the pipeline 3 is divided into the levels a to h, which are arranged at the same distance from each other.
  • the plane y lies on the outlet opening 22 and the plane x lies on the level of the control measuring sensor 24.
  • control measurements were carried out in the mentioned planes, the diagram shown in FIG. 3 resulting from pressure and temperature. T is the temperature in degrees Celcius and P is the vapor pressure in Pascal.
  • the "hot / cold" separation point is always kept at approximately the same level via the control system, so that a constant temperature at level x and complete filling of the damper housing with steam is ensured.
  • the pressure decreases with increasing distance from the damper housing and reaches the value 0 on the plane y or at the outlet opening 22.
