Definitions

  • the invention relates to a method for process control of an open anode furnace according to the preamble of claim 1 and to a device for measuring the operating state of an open anode furnace and to the process control according to the preamble of claim. 5
  • an open or covered anode baking oven is operated in such a way that the specialist staff operating the anode baking oven must rely on many years of professional experience which enables the employees to control the anode baking oven.
  • the temperature is measured at various locations in the anode furnace.
  • a disadvantage of such control of an anode furnace has been found that often the professionals are not able due to lack of information to make the optimal setting for the operation of the anode furnace, because the decisive for the optimal use of energy parameters can by the professionals insufficiently assessed and assessed.
  • a disability occurs within the air duct, which may lead locally within the anode furnace, that in this area of the anode furnace the Air volume flow rate is lowered, so that a temperature increase occurs, whereby, however, elsewhere, a temperature drop is present.
  • a device for the automatic automatic control of an anode furnace is not yet known.
  • This method is intended to provide measurement parameters by means of which control electronics automatically perform the process control of the anode furnace.
  • the life of the anode furnace is to be extended by the process management is within an optimal energy range.
  • the object of the invention for process control of the anode furnace is characterized by the features of the characterizing parts of claims 1 and 5, and the task for automatic process control of the anode furnace is achieved by the device according to the features of the characterizing part of claim 6.
  • the device By means of the device according to the invention or by means of the method it is possible to determine a heating channel index which is permanently adapted to the actual operating situation of the anode baking oven.
  • An electronic control unit associated with the device evaluates the determined measurement results and compares them with a predetermined or mathematically calculated actual operating state and adapts the actual operating state to the optimum actual value of the anode furnace. This advantageously avoids the need for specialized personnel to monitor and take over the process control of the anode furnace. Rather, precisely predetermined values of the process control of the anode furnace can be used as a basis for enabling an energetically optimal operation of the anode furnace.
  • the air throughput flowing through the anode baking oven is increased or reduced, specifically as a function of the actually necessary amount of air in the individual zones.
  • the amount of fuel to increase the power of the burner can be increased or decreased in order to obtain the necessary for burning the anodes optimum energy temperature.
  • the process control of the anode furnace is therefore fully automatic and requires only minor manual controls, for example, as to whether the measuring instruments used are in need of repair and provide correct readings. Such a fully automatic process furnace management therefore requires little staff, so that considerable personnel costs can be saved.
  • the process control is adapted to an energetically optimal course, the energy requirement to an extent necessary for the optimal operation of the anode furnace can therefore be reduced.
  • FIGS. 1 to 4 show an anode baking oven 2 to which a device 1 for process control is assigned.
  • the anode kiln 2 should be able to be automatically and automatically controlled without the need for elaborate monitoring by the operating personnel.
  • the anode furnace 2 shown in FIG. 1 consists of three individual fires, which are constructed identically. Based on the first fire, the structure and operation of the anode furnace 2 will be explained in more detail below. Each fire can be subdivided into three zones 3, 4 and 5, in which different operating conditions prevail. In zone 3, a plurality of anodes 7, which are to be fired, are introduced into a respective section 6. In zone 4, the embedded anodes 7 are to be fired by three burners 10 and in zone 5 the fired anodes 7 are to cool down.
  • an air channel 9 is present in the anode furnace 2, which connects the individual sections 6 and thus the zones 3, 4 and 5 with each other.
  • a throttle valve 13 is provided at the exit and at the entrance of the air duct 9, so that the amount of air sucked into the air duct 9 can be controlled.
  • the zone 3 and the air duct 9 emerging there is associated with a fan 14, via which the air is sucked through the zones 3, 4 and 5, so that there is negative pressure in the anode furnace 2. Accordingly, air enters the zone 5 with the usual ambient temperature of the environment in the anode furnace 2 and cools the heated anodes 7 from.
  • the further flowing air into the zone 3 accordingly has a further elevated temperature, so that the anodes 7 stored in the zone 3 are preheated.
  • the anode kiln 2 therefore represents in its entirety a control circuit in which three fires burn the encased anodes 7 circumferentially, cool the anodes in three zones or preheat and in another three Zones, the anodes can be stored for burning or the finished burned anodes 7 are discharged from the anode kiln 2.
  • an electronic control unit 12 is assigned to the anode furnace 2, specifically to each fire individually. Furthermore, in each of the sections 6, which form the zones 3, 4 and 5, temperature sensor 16, sensors 17 for the measurement of air flow and sensors 20 for measuring the opacity of the air, so the prevailing soot-particulate portions in the Air, available. The temperature sensors 16 and sensors 17 and 20 determine for each of the sections 6, the corresponding measured values, which are forwarded to the control electronics 12.
  • a heating channel index is calculated by the control electronics 12, which is composed of the measured temperature and / or from the measured air volume flow and / or from the supplied amount of fuel or the burning power of the burner 10 and / or from the opacity the fire generated by the burners 10 and / or from the negative pressure prevailing in the zone 3, 4 or 5 and / or from the resulting temperature gradient of the fire generated by the burners 10.
  • This heating channel index is now compared with an energetically optimal actual operating value of the anode furnace 2. If there are deviations, the control electronics 12 carries out a corresponding adaptation. As a result, the heating channel index is readjusted to the actual operating value.
  • Such an adjustment of the heating channel index to the actual operating value takes place, for example, in that the throttle flap 13 is further opened or closed at the inlet of the air duct 9, so that either more or less air passes into the anode kiln 2.
  • the burner power of the burner 10 can be adjusted by reducing or increasing the amount of fuel.
  • the control of the fan 14 allows an increase or decrease of the air flow.
  • Eirizelne throttle valves 13 are also mounted inside the anode furnace 2 in the air duct 9, so that in principle each section 6 is individually supplied with air.
