Definitions
- the invention relates to a method for operating a coke oven battery with a plurality of identical coking chambers, a raw gas supply and throttle devices arranged in the raw gas supply for individually regulating the gas pressure in the coking chambers.
- the throttling devices each have a water cup with a closable drain.
- the coking chambers are connected to the raw gas supply by gas lines which end as dip tubes in the immersion cups of the throttle devices.
- Throttling devices Flow measurement and control devices be provided both in the water inflow and in the water outflow. The control engineering effort for automated operation of the coke oven battery is great.
- the invention is based on the object of specifying a method which enables simple, safe operation of the coking chambers of a coke oven battery in terms of control technology.
- a coke oven battery with a plurality of identical coking chambers a raw gas supply and throttle devices arranged in the raw gas supply for individual regulation of the gas pressure in the coking chambers is required, the throttling devices each having a water-loaded immersion cup with a closable outlet and the coking chambers with the raw gas supply through gas lines are connected, which end as dip tubes in the immersion cups of the throttle devices.
- the object of the invention and solution of the above-mentioned object is a method for operating such a coke oven battery with the following features:
- Control of the actuator is assigned, the control signals for the actuator, which are associated with the pressure curve during the coking of coal to coke, are recorded in the form of a position-time curve;
- the actuators are controlled by throttle devices which are assigned to coking chambers without pressure regulating devices.
- the pressure control 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 be used the next or later Gas development cycles are used as control signals instead of the control signals coming directly from the pressure control unit.
- the position-time curve is also used to operate coking chambers that have no pressure control device.
- the pressure in the raw gas template is measured and correction values are applied to the functional values of the position-time curve if the pressure in the raw gas template deviates from a reference value measured when the position-time curve is recorded.
- This compensates for pressure fluctuations on the gas discharge side and does not have a detrimental effect on the operation of the coking chambers. Disturbances on the gas supply or generation side are generally known and are caused by changes in the operating parameters, e.g. when the coking times or the heating train temperatures change. In such cases, the position-time curve is recorded again.
- La and lb a section of a coke oven battery with a throttle device arranged in the gas path between a coking chamber and a raw gas supply, which is shown in different functional positions,
- FIG. 2 shows a longitudinal section through the throttle device in an enlarged view compared to FIGS.
- 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.
- FIGS. 1 a and 1 b show one of the coking chambers 1 with an associated throttle device and a section of the raw gas supply 2.
- the throttle device is arranged within the raw gas supply 2 of the coke oven battery and connected to the gas space of the coking chambers 1 via a riser pipe 3 (FIGS. 1 a, 1 b).
- the basic structure of the throttle device includes an immersion cup 4, to which water 5 is continuously supplied, and an immersion tube 6, which is connected to the ascending tube 3 via an ascending pipe elbow 7 and ends in the immersion cup 4.
- the immersion cup 4 has an overflow 8 and a closable outlet 9.
- the dip tube 6 is with a
- the free gas outlet cross-section depends on the liquid level 11 in the immersion cup 4.
- the end section has cut 10 jacket-side slots 12 (Fig. 2).
- the lower ante can be profiled or beveled.
- an outlet pipe 13 for water is provided to regulate the liquid level 11, the inlet end of which projects into the immersion pipe 6 and contains jacket-side inlet openings 14 for the inflow of water.
- a slide 15 which is open on both end faces and 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 water flowing into the drain pipe 13.
- the inlet-side end of the drain pipe 13 is surrounded by a siphon pipe 16, which closes the drain pipe 13 on the upper side and forms an annular channel for the inflow of water below the immersion pipe 6 into the immersion cup 4.
- the upper edge of the slide 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 negatively influence the water level control.
- the e.g. slot-shaped jacket-side recesses 12 in the end section 10 of the immersion pipe 6 extend in the longitudinal direction over a section a, the length of which is adapted to the adjustment range of the slide 15 within the drain pipe 13.
- the slider 15 is movable by an adjusting rod 17 which is guided through a section of the dip tube 6. It is through the wall of the riser pipe 7, the extension of which tion represents the immersion tube 6, led to the outside and connected there with a suitable actuator 18 (Fig. La, lb).
- a drive unit is expediently used as the actuator 18, which remains in the last control position if its drive energy fails, since this represents the position in which the combination of water level and gas pressure corresponds to a defined, safe state. This is particularly important for the removal of raw gas from the coking chamber, since the pressure here must neither rise nor fall too much.
- the jacket-side inlet openings 14 of the drain pipe 13, for example in the form of longitudinal slots, are closed by the slide 15.
- the immersion cup 4 is flooded by the incoming water.
- the water flows over the overflow 8 of the immersion cup 4.
- Liquid column b in the immersion tube 6 is so large that the gas path between the gas space of the coking chamber 1 and the raw gas supply 2 is interrupted.
- the coking chamber 1 can be opened and fully cooked coke can be squeezed out.
- the device according to the invention prevents air from getting into the raw gas receiver 2.
- the drain pipe 13- is connected as a movable adjusting element to a plug 19 assigned to the drain 9, the water flowing off in the drain pipe 13 flowing out through a water channel of the plug 19 sealing the immersion cup 4 (FIGS. 1 a and 2).
- the sealing plug 19 can be moved into the open position shown in FIG. 4 by a lifting movement of the drain pipe 13 and releases the drain 9 of the immersion cup 4 for emptying the immersion cup.
- the device according to the invention assumes the functional position shown in FIG. 4 when the assigned coking chamber 1 is freshly filled with coal. The filling gases are sucked into the raw gas supply 2 unthrottled with the negative pressure prevailing in the raw gas supply 2.
- the complete operating cycle of a coking chamber can be controlled or regulated.
- the immersion cup 4 is completely emptied, so that the filling gases can be sucked into the raw gas receiver 2 unthrottled with the negative pressure prevailing in the raw gas receiver 2.
- the chamber pressure is regulated by regulating 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 receiver 2.
- a comparative examination of the figures shows that the regulation, closing and opening of the gas path by a rectified movement of the slide 15 takes place.
- the liquid level can be regulated by the adjusting movements of the slide 15 (FIG. 2).
- the inlet openings 14 of the outlet pipe 13 can be closed by a further adjusting movement of the slide (FIG. 3).
- the slide 15 can be moved against a stop, for example the upper cover of the drain pipe 13, and carries the drain pipe 13 with the permanently connected sealing plug 19 with further stroke movement, the drain 9 of the immersion cup 4 being opened (FIG. 4 ).
- the required adjusting movements of the adjusting rod 17 are small, so that the functional steps can be carried out quickly.
- the actuating signals for the actuator are recorded in the form of a position-time curve for a coking chamber, which is assigned a pressure control device with a measuring device for the chamber pressure and with a position transmitter for controlling the actuator for the entire coking process.
- the actuators are then controlled by throttle devices which are assigned to coking chambers which have no pressure control devices.
- the throttling devices of the other coking chambers are controlled according to the recorded position-time curve that applies to all coking chambers.
- the pressure in the raw gas receiver is measured and the function values of the position-time curve correction values are applied when the pressure in the raw gas receiver deviates from a reference value measured when the position-time curve is recorded.
- 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 adjusted, standardized value, which stands for the position of the actuator or the spool.
- the described procedure 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 heating temperature. 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 in the event of serious changes in the operating parameters.
