Definitions

  • the invention relates to a device for regulating the gas pressure in a coke oven chamber with a dipping cup, which is fed water, as well a dip tube, which is connected to the gas space of the coke oven chamber and ends in the dip cup, wherein the immersion cup has an overflow and a closable drain and wherein the dip tube is formed with an end portion whose free gas outlet cross section is dependent on the liquid level in the immersion cup.
  • the dip tube has a telescoping extensible end piece.
  • the chamber pressure control is carried out by different dipping the tail in the master sump of the dipping cup. Due to the large dimensions of the gas-conducting dip tube a complex mechanism for adjusting the tail is required. Another problem is the sealing between the telescoping end piece and the dip tube.
  • the invention has for its object to provide a device for controlling the gas pressure in a coke oven chamber, which allows a direct and accurate control of the liquid level in the dip cup. It should be structurally simple and ensure a control technically simple, safe operation of the coke oven chamber.
  • a drain pipe for water is provided for controlling the liquid level, the inlet end of which projects into the dip tube and contains shell-side inlet openings for the inflow of water, that within the drain pipe on both sides open slider is arranged, which closes the inlet openings of the drain pipe in accordance with its position in the longitudinal direction and forms a vertically adjustable overflow for the water flowing into the drain pipe, and that the inlet end of the drain pipe is surrounded by a siphon tube which closes the drain pipe top side and forms an opening below the dip tube in the dip cup ring channel for the inflow of water.
  • the respective position of the upper edge of the slider defines the height of the water level within the immersion cup.
  • the water level can be controlled directly and very precisely.
  • the regulation takes place within the dip tube and thus on the gas supply side, where only small turbulences of the water surface can occur.
  • the relatively quiet water surface within the dip tube In contrast to the water surface outside the dip tube, which is strongly swirled by rising gas bubbles of the outflowing gas, allows the relatively quiet water surface within the dip tube a very precise adjustment and control of the liquid level.
  • the arranged at the inlet end of the drain pipe siphon which closes the drain pipe top and forms an opening below the dip tube in the dip cup ring channel for the inflow of water prevents gas flows through the drain pipe and negatively affected the scheme.
  • the gas is forced by the arrangement of the siphon pipe to take the path from the dip tube through the adjustable in height water immersion or - if not completely submerged - through the free gas outlet cross section of the dip tube.
  • the length of the siphon tube depends on the required control range for the adjustment of the liquid level. It is understood that the lower edge of the siphon tube must always be located below the level set in the immersion cup to prevent gas penetration.
  • the immersion cup can be flooded by the slide is moved to its uppermost position and thereby the shell-side inlet openings of the drain pipe are completely closed. A water drainage from the immersion cup is then no longer possible via the drain pipe.
  • a water column is established, which is determined by the overflow of the immersion cup.
  • the water column is dimensioned such that the gas path between the gas space of the coke oven chamber and a raw gas reservoir on the outflow side of the device is interrupted. In this operating position, the coke oven chamber can be opened and expressed coke can be expressed.
  • the immersion cup can also be completely emptied by the drain of the immersion cup is opened.
  • the gas space of the coke oven chamber without throttling the gas flow communicates with a raw gas reservoir on the outflow side of the device, so that gases are sucked off with the negative pressure prevailing in the raw gas reservoir.
  • This functional position is required to attach a coke oven chamber freshly filled with coal to the raw gas reservoir of a coke oven battery.
  • the drain pipe is connected as a movable actuator to a drain associated with the dipping cup sealing plug, wherein the effluent in the drain pipe flows through a water channel of the dipping cup sealing plug.
  • the plug is movable by a lifting movement of the drain pipe in an open position and are the drain of the immersion cup free.
  • an adjusting rod is connected to the slide. By a lifting movement of the control rod, the slide is movable against a stop of the drain pipe and leads the drain pipe with the firmly connected stopper with.
  • an actuator is advantageously used, which remains in case of failure of its drive energy in the final control position, since this represents a position in which the combination water level / gas pressure corresponds to a defined, safe operating state of the coke oven chamber. Since in the device according to the invention each control position of the slider working actuator directly and directly a water level in the dip cup can be assigned, the water level will not change in a technical defect of the actuator or after failure of the drive power. This is particularly important in the raw gas removal from the coke oven chamber, since the pressure may neither rise too high nor fall too much. In the former case, emissions may occur via the oven closures; in the latter case there is a risk of air in the coke oven chamber and thus a possible damage due to overheating. The last set water level before the failure of an actuator at the same time represents the safe position for the oven operation for this state.
  • the device shown in the figures is used to regulate the gas pressure in a coke oven chamber 1 of a coke oven battery. It is disposed within a raw gas 2 of the coke oven battery and connected via a riser pipe 3 with the gas space of the coke oven chamber 1 (Fig. 1a, 1b).
  • the basic structure of the device includes a dip cup 4, the water is constantly supplied 5, and a dip tube 6, which is connected via a riser pipe 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 whose free gas outlet cross-section is dependent on the liquid level 11 in the dip cup 4.
  • the end portion 10 has shell-side slots 12 (FIG. 2).
  • the lower edge may be profiled or bevelled.
  • FIG. 2 shows that, for the regulation of the liquid level 11, a drain pipe 13 for water is provided whose inlet-side end projects into the dip tube 6 and contains shell-side inlet openings 14 for the inflow of water.
  • a drain pipe 13 for water is provided whose inlet-side end projects into the dip tube 6 and contains shell-side inlet openings 14 for the inflow of water.
  • slide 15 Within the drain pipe 13, 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 dew cup 4.
  • the siphon tube 16 prevents gas from flowing through the drain pipe
  • 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 guided through the wall of the riser elbow 7, whose extension is the dip tube 6, to the outside and there connected to a suitable actuator 18 (Fig. 1a, 1b). It is expedient to use a drive unit as actuator 18 which, in the event of failure of its drive energy, remains in the last control position, since this represents that position at which the combination of water level / gas pressure corresponds to a defined, safe state. This is particularly important in the case of raw gas removal from the coke oven chamber, since the pressure must neither increase too much nor fall too much.
  • the liquid column b in the dip tube 6 is so large that the gas path between the gas chamber of the coke oven chamber 1 and the raw gas template 2 is interrupted.
  • the coke oven chamber 1 can be expressed open and abandonedgarter 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 movable by a lifting movement of the drain pipe 13 in the open position shown in Fig. 4 and are the flow 9 of the dipping cup 4 for emptying the immersion cup free.
  • the inventive device assumes the functional position shown in Fig. 4, when the associated coke oven chamber 1 is freshly filled with coal. The filling gases are with the in the raw gas template 2 prevailing negative pressure unthrottled sucked into the raw gas 2 template.
  • the entire operating cycle of a coke oven 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.
  • a comparative consideration of the figures takes one that the rules, closing and opening the gas path by a rectified movement of the slider 15 takes place.
  • the liquid level can be controlled (Fig. 2).
  • the inlet openings 14 of the drain pipe 13 are closed (Fig. 3).
  • the slider 15 is against a stop, e.g. the upper lid of the drain pipe 13, movable and leads with further lifting movement, the drain pipe 13 with the fixedly connected closure plug 19, wherein the outlet 9 of the immersion 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.
