Definitions

  • the invention relates to a method for regulating the outflow from a rain basin or a sewer pipe of a sewerage system through an undamped drain pipe and a system for carrying out the method.
  • Undamped drain pipes can also run completely or partially empty when the throttle element is open, so that the flow through them can become very small in dry weather.
  • the regulation of the nominal discharge is normally switched off and the throttle element is transferred to and held in a predetermined first position, in which the undamped drain pipe is open for the flow of waste water, so that it can be flowed through even in dry weather from the rainwater or sewer pipe. If there is a risk of exceeding the nominal value of the flow of the drain pipe, first fill the area of the flow measuring point of the drain pipe brought about and then the control of the nominal discharge switched on. This regulation is ended again, and the throttle body is returned to its first position when the water level in the rain basin or sewer pipe falls below a predetermined level, at which the area of the flow measuring point of the drain pipe is still completely full.
  • the drain pipe can be completely or partially run empty and only small amounts of waste water / time flow through it so that there is a risk of heavier deposits of sludge, sand, faeces or the like in the sewer pipe or sewer downstream of the drain pipe.
  • the drain pipe is flowed through or completely shut off only with relatively large amounts of waste water / time corresponding to the nominal value of the flow.
  • this relatively large nominal flow rate which is provided in such a way that the downstream sewerage, sewage treatment plant or the like does not become overloaded, there is a risk of heavier deposits in the sewer pipe or sewer downstream of the drain pipe are considerably reduced or completely eliminated because of the relatively high flow rates of the waste water.
  • the drain pipe is shut off, so that no sludge, sand or other contaminants can get into the sewer pipe or sewer downstream from it.
  • this method according to the invention can therefore also serve to quantify the total wastewater runoff from the rain basin or the sewer pipe by adding up the measured values of the flow measuring device. This is an important advantage, since it is often desirable, for example for cost calculations, planning, statistical purposes or the like. To sum up the amount of wastewater flowing out of the rain basin or the like in certain periods or in total even in dry weather.
  • the discharge of the waste water takes place under regulation of the nominal discharge and it can, if necessary, be provided from time to time, the discharge temporarily with anomalous shutdown of the regulation of the nominal value or increase of the nominal value of the regulation, preferably only for a relatively short time to increase in order to flush away dirt and mud and the like.
  • the drain pipe at the flow measuring point is completely filled with waste water and the flow meter also measures the flow exactly, so that in the event of the accumulation of the flow rate this drain is also included detected. If there is no danger that inadmissibly strong deposits in front of the flow measuring point can accumulate, of course, the measure according to claim 6 need not be provided.
  • the invention thus also enables detection of the total flow through the drain pipe by summing up the flow rate.
  • This summation can take place in an integrator or another counter.
  • the total amount of wastewater can be displayed and / or registered, for example.
  • the display or registration can be done, for example, in cubic meters. This integrator or the like. So forms a wastewater meter.
  • an inlet channel 11 and a straight, almost horizontally laid undressed drain pipe 13 are connected, which penetrates a dry slide shaft 12.
  • This drain pipe 13 can be variably throttled and blocked by means of a throttle member 14 adjustable by an actuator 16.
  • Actuator 16 can be designed as a servomotor, for example as an electric motor or electromagnetic actuator, or as a hydraulic or pneumatic lifting cylinder or the like, which acts on the throttle member 14 designed as a slide or pivotable throttle valve.
  • This flow measuring device 21 can preferably be an inductive flow measuring device measuring the flow rate or an ultrasonic measuring device, but possibly also another suitable measuring device. Furthermore, two water level sensors designed as pressure switches 24, 25 are arranged in the drain pipe 13 and are used to detect two predetermined water levels W1 and W2 in the rain basin 10. The lower predetermined water level W1 is provided so that, on the one hand, the drain pipe 13 in the area of the flow measuring point 33 is completely filled, so that the measuring device 21 can measure the flow precisely and, on the other hand, through it the flow rate corresponding to the nominal value of the flow rate the drain pipe can be effected, preferably a significantly larger flow when the throttle member 14 is fully open.
  • the output signal of the flow measuring device 21 is applied as an actual value to the actual value input of a controller 23, at its setpoint input the setpoint value which can be set by means of a setpoint adjuster 22 of the nominal runoff of the rainbow 10 is entered.
  • the controller 23 forms the difference between this setpoint and the measured actual value as a control deviation and, depending on this, generates switching signals that enlarge and reduce the effective cross-section at the throttle point via the actuator 16 and the throttle element 14 to regulate the respective control deviation or when the control is switched off completely block the drain.
  • the controller 23 can be switched on and off via a bistable switching element 26, the pressure switch 24 being connected to its set input S and the pressure switch 25 being connected to its reset input R.
  • the assemblies 22, 23, 26 are contained in an electronic regulating and control device 27, which can preferably be part of a microprocessor.
  • An integrator 28 summing up the measurement signals of the flow measuring device 21, which are present, for example, as a signal sequence with a flow rate-dependent frequency and which can also be referred to as a wastewater flow meter, serves to record the total wastewater flow rate through the drain pipe 13.
  • the summation of the measurement signal can also be carried out in the device 27 and the resulting numerical value can be registered and / or displayed.
  • the counter or integrator 28 can be read at the desired times and the difference between the numerical values read at two different times then gives the total flow through the drain pipe 13 in the relevant time period Amount of waste water. Provision can also be made for the counter or integrator 28 to be used only temporarily if the flow rate is to be totalized.
  • the controller 23 then regulates, via the throttle element 14, the flow of the drain pipe 13 caused by the flowing waste water to the nominal value specified by the set point adjuster 22. If the water level drops to the value W1 as a result of the A b flow, the pressure switch 24 generates a set signal for the bistable switching element 26, which thereby switches off the controller 23, as a result of which the actuator 16 for immediately shutting off the drain pipe 13 by means of the throttle element 14 is controlled. This means that there is no longer any waste water runoff.
  • the outflow is not resumed until the controller 26 is switched on again.
  • the controller 23 can be switched off, for example, by setting the setpoint to the value zero. Because of the shutoff of the drain pipe 13, the water level in the rain basin 10 rises again. In this way, it can never fall significantly below the value W1, so that the drain pipe 13 at the flow measuring point is always completely filled with waste water. and this, in spite of the fact that it could be completely or partially empty in the area of the flow measuring point 33 when the throttle element 14 is open, but this is prevented by the control described.
  • the second pressure switch 25 responds and generates a reset signal for the bistable switching element 26.
  • the controller 23 thereby becomes switched on again and now regulates the discharge of the waste water to the nominal value of the flow of the drain pipe 13 again via the throttle element 14. Sooner or later the water level drops again to below the value W1, and then the shutoff of the drain pipe 13 and switching off is repeated of controller 23.
  • the response threshold of the second pressure switch 25 is expediently adjustable so that the water level W2 can be expediently set.
  • a further adjustability results from variation of the setpoint by the setpoint adjuster 22 or by abnormal switching off of the controller 23, for example with the throttle element 14 fully open, in order to achieve a discharge amount above the nominal value from time to time for flushing away deposits in front of the throttle point 14 .
  • This abnormal shutdown of the controller 23 or increase in its setpoint can occur during the entire time of a shutdown sinking of the water level from W2 to W1 or by shorter, stronger, preferably maximum opening of the throttle member 14.
  • This switching off of the control or increasing the setpoint in order to increase the outflow can, for example, be done manually or programmed, for example with or after every nth control of the nominal outflow, where n can be, for example, 10 to 50, or in other suitable longer time intervals if it is necessary at all.
  • FIGS. 1 Shown on the in Fig. 2, in a slider shaft 12 as shown in FIGS. 1 arranged drain pipe 13, instead of a rain basin 10, a sewer pipe 30 laid with a slope is connected. To simplify FIG. 2, individual assemblies in the slide shaft 12 are not shown again.
  • the mode of operation of the embodiment shown in FIG. 2 can correspond to the embodiment described above.
  • the throttle element 14 is closed, the water level in the sewer pipe 30 rises here.
  • the system shown in FIG. 3 differs from that of FIG. 1 essentially in that the water level sensor 24 for sensing the first water level W1 in the rain basin 10 has ceased to exist and a timer 32 is provided in its place.
  • This timer 32 is activated by the pressure sensor 25, which responds to the second water level W2, at the same time as the controller 23 serving to regulate the nominal value of the flow through the drain pipe 13, and then measures a predetermined period of time, for example 10 minutes to 1 hour, in this way It is dimensioned that even if there is no supply of waste water to the rain basin 10, by regulating the nominal value of the flow of the drain pipe 13, a predetermined first water level W1 in the rain basin cannot be undershot.
  • This first water level W1 which is not felt in this case, is considerably lower than the water level W2, but is still so large that the flow measuring point of the drain pipe, ie its clear cross section in the area of the flow measuring point, is still completely filled with waste water.
  • This determination of the time period to be measured by the time switching device 32 with the first water level W1 on which it is based can, for example, like the water level W1 of the system according to FIG. 1, correspond to the clear apex height of the straight drain pipe 13 lying horizontally in this exemplary embodiment or be slightly above it.
