Definitions

the invention relates to a cooler for dry coke cooling with a prechamber arranged in its upper part and extending into the area below the discharge line for the gaseous cooling medium, webs being attached to the outside of the prechamber which are evenly distributed over the entire circumference and which provide the Connect the antechamber to the radiator jacket.
a cooler of the type mentioned is described in German patent application P 30 09 818.1.
the hot coke introduced into the cooler from above forms an embankment when it emerges from the prechamber, through which a closed annular space is created between the inside of the cooler and the outside of the prechamber. Since the connection of the exhaust line for the cooling gases is also located in this area, the hot cooling gases escaping from the coke to be cooled can reach the exhaust line and the subsequent units via the annular space.
the cold cooling gases are usually applied at the lower end or in the middle area of the cooler. In practical operation of the cooler, special attention must be paid to ensuring that the hot cooling gases emerge evenly over the entire circumference of the annulus.
the existing webs already achieve a certain leveling out of the hot cooling gas stream rising from the coke.
the invention is therefore based on the object of further improving the cooler of the type mentioned with regard to the uniformity and the influencing and controllability of the hot cooling gas stream rising from the coke, in particular also influencing the flow conditions during practical operation of the cooler . At the same time, care should be taken to ensure that the construction is as simple, inexpensive and safe as possible.
the cooler used to achieve this object is characterized according to the invention in that the btege have support surfaces on both sides, on each of which support stones are arranged between two webs, the insertion and positioning of which are carried out by means of inspection hole closures arranged in the upper part of the cooler.
the prechamber is designated by 1. This is arranged within the upper part 8 of the cooler so that it lies on the same center axis with the upper part 8. Between the antechamber 1 and the upper part 8 there is the annular space 3 with the exhaust port 2, through which the hot cooling gases rising from the lower part 4 of the cooler reach the exhaust line for the gaseous cooling medium, not shown.
the jacket 5 of the pre-chamber 1 is made of refractory material and has on the outside in the lower part of the webs 6, which also consist of refractory material. These are evenly distributed over the entire circumference of the prechamber 1 and connect the prechamber 1 to the radiator jacket 7.
the webs 6 have a double function here: on the one hand they serve to support the antechamber 1 and on the other hand they are intended to make the flow of the hot gases rising from the lower part 4 of the cooler more uniform so that they are better over the entire cross section distribute the annulus 3. So that the flow conditions can actually be even better adapted to the particular circumstances of practical operation, the webs 6 also have the support surfaces 9 on both sides, on which 6 support stones 10 can be arranged in each case between two webs. The free cross section of the gas passages 13 between the webs 6 can be varied by the number and the position of these support stones 10 and thus influence the tensile and pressure conditions in the cooler.
the support stones 10 are introduced into the cooler through the inspection hole closures 11, which are arranged in the upper part 8 of the cooler above the annular space 3.
the support stones 10 are preferably made of a suitable refractory material and are provided with a bore 12 for receiving the insertion tool, e.g. Hook, provided. With the aid of this insertion tool, the support side 10 is lowered into the cooler through the inspection hole closures 11 opened for this purpose and placed on the support surfaces 9 in the desired position, or in the opposite manner removed from the cooler.
the support blocks 10 can also be inserted or removed during the operation of the cooler.
Fig. 2 shows a part of the plan view of the annular space 3 between the prechamber 1 and the upper part 8 of the cooler and shows how the free cross sections of the gas passages 13 between the webs 6 are varied by the number and position of the support stones 10 and thus can be adapted to the actual circumstances.
FIG. 3 finally shows two adjacent webs 6 with the contact surfaces 9 on both sides and the contact stones 10 located thereon. It can be seen from FIG. 3 that the contact surfaces 9 in this case have bevels on the underside through which the flow conditions in the gas outlets 13 can be improved. In addition, the bores 12 in the support stones 10 are clearly visible in this case.
