Definitions

  • the invention relates to a method for operating a coke oven battery having a plurality of identical coking chambers, a raw gas supply and arranged in the raw gas template throttle devices for individually regulating the gas pressure in the coking.
  • the throttle devices each have a water immersed immersion cup with a closable drain.
  • the coking chambers are connected to the raw gas feed through gas lines which terminate as dip tubes in the dip cups of the throttle devices.
  • Such throttle devices are off EP 0 649 455 B1 and WO 94/01513 A known.
  • the gas pressure of the associated coking chamber can be regulated as a function of the gas release.
  • the change of the liquid level in the immersion cup takes place indirectly by controlling the water inflow and outflow.
  • This equilibrium water conditions set which are dependent on the static pressure of the water column in the immersion cup and the free cross section of the drain opening and change in fluctuations in the feed rate or the discharge rate.
  • complex control is required to determine the water inflows and outflows during the coking process. All coking chambers must be equipped with measuring devices for chamber pressure. Furthermore, flow meters and control devices must be fitted to the throttle devices be provided both in the inflow and outflow of water. The control engineering effort for an automated operation of the coke oven battery is great.
  • the invention has for its object to provide a method that allows a simple control, safe operation of the coking chambers of a coke oven battery.
  • a coke oven battery with a plurality of the same coking, a raw gas and arranged in the raw gas throttle devices for individually regulating the gas pressure in the coking, wherein the throttle devices each have a water-immersed immersion cup with a closable outlet and wherein the coking with the raw gas template by gas lines are connected, which end as a dip tubes in the immersion cups of the throttle devices.
  • the invention and solution of the above object is a method for operating such a coke oven battery, wherein Throttle devices are used which have a vertically adjustable by an actuator overflow for controlling the liquid level in the immersion cup, for a coking chamber, which is associated with a pressure regulating device with a measuring device for the chamber pressure and with a position sensor for controlling the actuator, which are recorded in the form of a position-time curve associated with the temporal pressure curve during the coking coal to coke associated actuating signals for the actuator in accordance with the position-time curve, the actuators are controlled by throttle devices associated with coking chambers without pressure control devices.
  • the inventive method makes use of the fact that the coking in the coking chambers is a cyclic batch process and the evolution of gas during coking has a predictable course that is the same in all coking chambers.
  • This makes it possible to control the liquid level in the immersion cup according to a position-time curve, which is stored in a process computer.
  • the position-time curve is transmitted as control signals from the process computer to the actuators of the throttle devices, which position the associated overflow according to the control signals.
  • it is sufficient if only one or a few coking chambers in the coke oven battery are equipped with a pressure regulating device.
  • the pressure regulating device comprises a measuring device for the chamber pressure and a position transmitter, which generates control signals for the actuator of the vertically adjustable overflow from the pressure values and setpoints.
  • the transmitted control signals are stored for one or each gas development cycle as a position-time curve and can then at the next or at later Gas development cycles are used as control signals instead of directly coming from the pressure control unit control signals.
  • the position-time curve is also used to operate coking chambers, which have no pressure control device.
  • the pressure in the raw gas sample is measured and the function values of the position-time curve correction values are activated when the pressure in the raw gas sample deviates from a reference value measured during the recording of the position-time curve.
  • Pressure fluctuations on the gas discharge side are compensated for and do not adversely affect the operation of the coking chambers. Disturbances on the gas supply or generation side are generally known and are dependent on changes in the operating parameters, e.g. caused by a change in the coking times or the Schuzugtemperaturen. In such cases, the position-time curve is recaptured.
  • the invention relates to a method for operating a coke oven battery, which has a plurality of identical coking chambers, a raw gas supply and throttle devices for individually regulating the gas pressure in the coking chambers.
  • a coke oven battery which has a plurality of identical coking chambers, a raw gas supply and throttle devices for individually regulating the gas pressure in the coking chambers.
  • a raw gas supply and throttle devices for individually regulating the gas pressure in the coking chambers.
  • Fig. 1a and 1b one of the coking chambers 1 with associated throttle device and a section of the raw gas template 2 is shown.
  • the throttle device is disposed within the raw gas feed 2 of the coke oven battery and connected via a riser pipe 3 with the gas space of the coking chamber 1 ( Fig. 1a, 1b ).
  • the basic structure of the throttle device includes a dip cup 4, the water is constantly fed 5, and a dip tube 6, which is connected via a riser manifold 7 with the riser pipe 3 and ends in the dip cup 4.
  • the immersion cup 4 has an overflow 8 and a closable outlet 9.
  • the dip tube 6 is formed with an end portion 10, the free gas outlet cross-section is dependent on the liquid level 11 in the dip cup 4.
  • the end portion 10 shell-side slots 12 on ( Fig. 2 ).
  • the lower edge may be profiled or bevelled.
  • a drain pipe 13 is provided for water, the inlet end of which protrudes into the dip tube 6 and shell-side inlet openings 14 for the inflow of water.
  • an open at both ends of slide 15 is arranged, which closes the inlet openings 14 of the drain pipe 13 in accordance with its position in the longitudinal direction and forms a vertically adjustable overflow for the inflowing into the drain pipe 13 water.
  • the inlet end of the drain pipe 13 is surrounded by a siphon pipe 16, which closes the upper side of the drain pipe 13 and forms an opening below the dip tube 6 in the dip cup 4 annular channel for the inflow of water.
  • the upper edge of the slider 15 defines the height of the water level within the immersion cup 4.
  • the siphon tube 16 prevents gas from flowing through the drain pipe 13 and can adversely affect the water level control.
  • the e.g. Slot-shaped shell-side recesses 12 in the end portion 10 of the dip tube 6 extend in the longitudinal direction over a portion a, whose length is adapted to the adjustment range of the slider 15 within the drain pipe 13.
  • the slider 15 is movable by a control rod 17 which is guided by a portion of the dip tube 6. It is through the wall of the riser 8, its extension represents the dip tube 6, led to the outside and there connected to a suitable actuator 18 ( Fig. 1a, 1b ).
  • a drive unit is used as the actuator 18, which remains in case of failure of its drive energy in the last control position, as this represents that position in which the combination water level / gas pressure corresponds to a defined, safe state. This is especially important in the case of raw gas removal from the coking chamber, since the pressure must neither increase too much nor fall too much.
  • Fig. 3 shown functional position of the device, for example, formed as longitudinal slots shell-side inlet openings 14 of the drain pipe 13 are closed by the slider 15. Due to the incoming water, the dipping cup 4 is flooded. The water flows through the overflow 8 of the immersion cup 4. The liquid column b in the dip tube 6 is so large that the gas path between the gas chamber of the coking chamber 1 and the raw gas template 2 is interrupted. The coking chamber 1 can be opened and expressed coke coke. The device according to the invention prevents air from entering the raw gas feed 2.
  • the drain pipe 13 is connected as a movable actuator to a drain 9 associated closure plug 19, wherein the effluent in the drain pipe 13 water flows through a water channel of the dipping cup 4 sealing plug 19 ( Fig. 1a and 2 ).
  • the plug 19 is by a lifting movement of the drain pipe 13 in the in Fig. 4 shown opening position movable and are the flow 9 of the dipping cup 4 for emptying the immersion cup free.
  • the inventive device takes the in Fig. 4 illustrated functional position when the associated coking chamber 1 is freshly filled with coal. The filling gases are sucked unthrottled into the raw-gas template 2 with the negative pressure prevailing in the raw-gas template 2.
  • the complete operating cycle of a coking chamber can be controlled or regulated.
  • the dipping cup 4 is completely emptied so that the filling gases can be sucked unthrottled into the raw gas template 2 with the negative pressure prevailing in the raw gas template 2.
  • the chamber pressure is regulated by regulation of the liquid level in the device according to the invention in accordance with a preset value.
  • the gas path is interrupted by flooding the immersion cup 4, so that no air can get into the raw gas 2 template. From a comparative analysis of the figures, one can deduce that the regulation, closing and opening of the gas path by a rectified movement of the slider 15 takes place.
  • the fluid level can be controlled ( Fig. 2 ).
  • the inlet openings 14 of the drain pipe 13 are closed ( Fig. 3 ).
  • the slide 15 is against a stop, for example, the upper lid of the drain pipe 13, movable and leads to further stroke movement, the drain pipe 13 with the firmly connected stopper 19, wherein the outlet 9 of the dip cup 4 is opened ( Fig. 4 ).
  • the required positioning movements of the control rod 17 are small, so that the functional steps can be performed quickly.
  • the control signals for the actuator in the form of a position-time curve recorded and indeed for the entire coking process.
  • the actuators are controlled by throttle devices associated with coking, which have no pressure control devices.
  • the pressure in the raw gas sample is measured, and the function values of the position-time curve correction values are displayed when the pressure in the raw gas sample deviates from a reference value measured during the recording of the position-time curve.
  • the position of the slide or the actuator is determined by direct assignment, which is then set.
  • the (theoretical) raw gas volume flow-time curve does not reflect the actual raw gas volume flow over the cooking time but rather one of the Pressure difference between chamber and template cleaned, standardized value, which stands for the position of the drive or the slider.
  • the procedure described compensates for pressure fluctuations on the gas discharge side. Disturbances on the gas supply or generation side are generally known and occur primarily only when changes to the operating parameters, e.g. the cooking time or Schuuchtemperatur be made. Such changes can be taken into account by recapturing the position-time curve for the control of the actuators at regular intervals, or at least during serious changes in the operating parameters.
