Description
~9~
1 The present invention relates to a cooler for coke dry cooling.
Coolers of the above-mentioned general type axe known in the art. The known coolers have a housing including an upper part and a lower part, a prechamber extending to the region be-low a suction conduit for gaseous cooling medium, and a plural-ity of connecting members provided at an outer side of the pre-chamber and distributed uniformly over its periphery so as to connect the prechamber with the housing. Such a cooler is known from prior art. During operation of such a cooler, hot coke supplied from above into the cooler forms a pile when i-t leaves the prechamber, so that a closed annular space is formed between the inner side of the cooler and the outer side of the prechamber. Since in this region a connection to the suction conduit for the cooling gas is located, hot cooling gas as exiting from the coke to be cooled can travel via the annular space into the suction conduit and the subsequently provided aggregate. The cold cooling gas is normally supplied at the lower end or in the central region of the cooler.
In practical operation of the cooler, it is especially important to provide for uniform distribution of the hot cooling gas over the entire periphery of the annular space. In the cooler described hereinabove, the connecting members or webs carry out the dis-tri-bution of hot cooling gas stream rising from the coke. It has, however, been shown that this construction cannot provide in:Eluence or adjustment of hot cooling gas stream so as to satisfy requirements which take place in practical use of the cooler.
Accordingly, it is an object of the present invention .,~', 1 to provide a cooler for dry coke cooling which avoids the disadvantages of the prior art.
More particularly, it is an object of the present invention to provide a cooler for dry coke cooling which further improves a possibility to influence and adjust the hot cooling gas stream rising from the coke so as to satis-fy practical requirements during operation of the cooler.
It is another object of the present invention to provide a cooler for dry coke cooling which has a simple and inexpensive as well as a reliable construction.
In keeping with these objects, and with others which will become apparent hereinater, one feature of the present invention resides, briefly stated, in a cooler for coke dry cooling having a housing with upper and lower hous-ing parts and a prechamber connected with the housing by a plurality of connecting members forming passages therebetween, wherein means is provided for adjusting a cross section of said passages and including a plurality of blocks insertable into the housing to at leas-t partially close respective ones of the passages, and withdrawable from the housing.
When the cooler for coke dry cooling is designed in accordance with the present invention, it provides for a possi-bility to control or adjus-t the hot cooling gas flow.
Another feature of the present invention is that the connecting members can be provided with supporting surfaces at two sides of each connecting member, and the blocks are support-ed on the supporting surfaces of two neighboring connecting mem-bers.
Still another feature of the present invention is that several blocks can be located between two neighboring ~9~
1 connectinq members in direction transverse to -the direction in which -the connecting members are spaced from one another.
~ fur-ther feature of the present inven-tion is that the housing is provided with means allowing the insertion and withdrawal of the blocks. This means can be formed as inspec-tion holes with closures which close and open the inspectlon holes.
Finally, -the blocks can be provided with means for engaging -thereof by a tool for insertion and withdrawal of the blocks. This engaging means can be formed as openings provided in each of the blocks.
The novel features which are considered character-istic for the invention are set forth in particular in the appended claims. The invention itself, however, bothas -to its construction and its method of operation, together wi-th additional objects and advan-tages thereof, wilI be best understood from the following description of preferred em-bodiments when read in connection with the accompanying draw-ing.
FIG. 1 is a view showing a longitudinal section of a cooler for coke dry cooling, in accordance with the present invention;
FIG. 2 is a fragment of a plan view of the inven-tive cooler shown in FIG. l; and FIG. 3 is a side view showing two neighboring con~
necting members with blocks located therebetween in the cooler designed in accordance with the invention.
FIG. 1 shows a central part of a cooler for dry coke cooling in accordance with the present invention. Only those parts of the cooler are shown which are important for under-9~
1 standing of the invention. An upper end of the cooler with a device for feeding coke to be cooled, a lower end of the cooler with a device for di.scharging the cooled coke, and gas inlet pipes are not shown in the drawing. The invention deals with a cooler in which coke to be cooled is supplied from above, and a gaseous cooling medium is supplied in a counterstream from below.
The cooler has a prechamher which is identi:Eied by reference numeral 1. The prechamber 1 is located inside an upper part 8 of the housing of the cooler so that the axes of the prechamber 1 and the upper housing part 8 coincide with one another. An annular space is formed between the precham-ber 1 and the upper housing part 8, and a suction opening ex-tends from the annular space 3. A hot cooling gas rises from the lower part 4 of the housing of the cooler and travels through the opening 2 to a not-shown suction device for the gaseous cooling medium.
The prechamber 1 has a wall 5 which is composed of a refractory material. A plurality of connecting members or webs 6 are arranged at the outer side of the lower part of the prechamber 1. The webs 6 are also composed of a refract-ory material. The webs 6 are uniformly distributed over the entire periphery of the prechamber 1 and connect the wall 5 of the prechamber 1 with a wall 7 of the cooler housing.
The webs 6 perform two functions. On the one hand, they serve for supporting the prechamber 1, and on the other hand they uniformly distribute the stream of ho-t gas rising from the lower housing part 4 of the cooler, so that this stream is better distributed over the entire cross section of the annular space 3.
1 In order to adjust the stream characteristics to the respective requirements of practical operation, each of the webs 6 is provided at both its sides with supporting sur-Eaces 9, and blocks 10 can be arran~ed between two neighbor-ing webs 6 so as to be supported by the supporting surfaces 9.
The free cross section of passages 13 which are formed between the webs 6 can be varied by the number and position of the above-mentioned blocks 10. Therefore the suction and pressure conditions in the cooler can be controlled.
lQ The blocks 10 can be introduced into the cooler through inspection holes provided with closures 11 which open and close the holes. The inspection holes are arranged in the upper housing part 8 of the cooler above the annular space 3.
The block 10 is composed, for example, of a suitable refractory material and provided with an opening 12 for engaging by a tool, such as a hook, to insert and withdraw the blocks. With the aid of this tool, the blocks 10 can be lowered through the opened inspection holes 11 and placed onto the supporting surfaces 9 of the respective webs 6 in the desired positions. This tool also withdraws the blocks from the cooler in reverse order. It is to be understood that the blocks 10 can be introduced into the cooler and withdrawn from the latter during operation of the cooler.
The blocks 10 have such dimensions that they can be inserted between the webs 6 and supported on the supporting sur-faces 10 of the latter.
FIG. 2 shows a part of a plan view of the annular space 3 between -the prechamber 1 and the upper housing part 8 of the cooler. It can be seen from this Figure that the number and posi-tions of the blocks 10 controlling the free cross ~9~
1 section of the passages 13 can be varied and thereby adapted to the respective operational requirements. One block 10 can be inserted between two neighboring webs 6. On the other hand, two or more blocks L0 can be inserted between two other neigh-boring webs 6 and located adjacent to one ano-ther in a direction which is transverse to the circumferential direction of the an-nular space.
FIG. 3 shows two neighboring webs 6 with the support-ing surfaces 9 at both their sides, and the blocks 10 resting on the supporting surfaces. As can be seen from FIG. 3, the webs 6 are formed in the region of the supporting surfaces 9 with a section decreasing downwardly. This involves the flow conditions in the passages 13.
At the same time, this reinforces the webs 6 in the region of their supporting surfaces. Moreover, this Figure clearly shows the openings 12 provided in the blocks 10.
In the cooler in accordance with the present inven-tion the problem of adaptation of flow conditions in the cooler in dependence upon the particular operational requirements is solved in extremely simple and inexpensive manner. High tech-nical expenses which are involved, for example, by utilization of so-called control valves for the same purpose, can be dis-pensed with.
It will be understood that each of the elements described above, or two or more together, may also find useful application in other types of constructions differing from the types described above.
While the invention has been illustrated and described as embodied in a cooler for dry coke cooling, it is not intended to be limited -to the details shown, since various modifications 1 and structural chan~es may be made without departin~ in any way Ero~ the spiri.-t of the present invention.
Without further analysis, the for~going will so fully reveal the gist of the present invention that others can, by applying current knowledye, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects o this invention.
