Abstract
The utility model discloses raw coke over gas riser heat recovering device supporting structure, it comprises inner core and urceolus, described inner core and urceolus are combined into upcast chuck, the below of described upcast chuck is provided with sustained ring and carrying cylinder, described sustained ring is connected with bottom upcast chuck, and carrying cylinder is plugged in the ring groove on sustained ring.Have the following advantages: because having set up sustained ring, therefore carrying cylinder and upcast chuck are not rigidly connected, and are conducive to each several part free expansion, can not produce thermal stresses and destroy structure.
Description
Technical field
The utility model belongs to ferrous metallurgy energy-saving and emission-reduction, secondary energy recovery technology field, particularly a kind of raw coke over gas riser heat recovering device supporting structure.
Background technology
Existing raw coke over gas riser heat recovering device and coking chamber discharge coupling, bridge tube are generally and are rigidly connected.As shown in Figure 1-2, carrying cylinder 1 welds with upcast chuck 2.When raw gas temperature cyclic fluctuation, between carrying cylinder 1 and upcast chuck 2, easily expand inequality, and then produce larger thermal stresses, the accident of breaking plant structure even occurs, affects the safe and stable operation of whole residual neat recovering system.
Utility model content
Technical problem to be solved in the utility model is, a kind of raw coke over gas riser heat recovering device supporting structure is provided, solves existing raw gas upcast heat recovering device carrying cylinder and upcast chuck non-homogeneous expansion, the easy problem producing thermal stress damage.
For solving the problems of the technologies described above, the raw coke over gas riser heat recovering device supporting structure that the utility model provides, it comprises inner core and urceolus, described inner core and urceolus are combined into upcast chuck, the below of described upcast chuck is provided with sustained ring and carrying cylinder, described sustained ring is connected with bottom upcast chuck, and carrying cylinder is plugged in the ring groove on sustained ring.Because having set up sustained ring, therefore, carrying cylinder and upcast chuck have not been rigidly connected, and are conducive to each several part free expansion, can not produce thermal stresses and destroy structure.
As preferably, in described upcast chuck, be provided with spiral pipe and fused salt heat-conducting medium, the described space of fused salt heat conducting medium filling between upcast chuck and spiral pipe.Select fused salt as the heat-conducting medium of upcast chuck, Heat-resistant stable is good, and fused salt does not explode, do not burn, corrodibility is low, produces steam hardly when less than 600 DEG C, even if reveal its steam also nontoxicity, under normal pressure, higher use temperature can be reached, be suitable for very much reclaiming crude-gas sensible heat.
As preferably, described inner core welds with urceolus after turning up in bottom, and urceolus welds with inner core after flanging in top.Inner core welds with urceolus after turning up in bottom, and weld seam is not contacted with high temperature raw gas, and water jacket technology often occurred in the past weld seam can be avoided to be heated cracking phenomena.
As preferably, the fused salt heat-conducting medium in described upcast chuck is Molten Binary Salts or ternary molten salt.Which kind of fused salt of concrete selection and molten salt membrane are depending on coal oven dithio-gas character and the steam parameter that will produce.
As preferably, described sustained ring is positioned at the middle position bottom upcast chuck.Better stressed, be conducive to the Stability Analysis of Structures of whole upcast chuck.
As preferably, described sustained ring welds with upcast chuck.
After adopting above structure, raw coke over gas riser heat recovering device supporting structure of the present utility model compared with prior art, has the following advantages:
1) because having set up sustained ring, therefore carrying cylinder and upcast chuck are not rigidly connected, and are conducive to each several part free expansion, can not produce thermal stresses and destroy structure.
2) carrying cylinder is positioned at upcast chuck bottom center, better stressed, is conducive to the Stability Analysis of Structures of whole upcast chuck.
3) whole support structure architecture is simple, easy to process, is easy to installation and removal.

Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 3-4, the raw coke over gas riser heat recovering device supporting structure that the present embodiment provides, it comprises inner core 13 and urceolus 14, described inner core 13 and urceolus 14 are combined into upcast chuck 12, the below of described upcast chuck 12 is provided with sustained ring 15 and carrying cylinder 11, described sustained ring 15 is welded on upcast chuck 12 lower center position, and carrying cylinder 11 is plugged in the ring groove on sustained ring 15.
Inner core 13 turns up after 180 ° in bottom and welds with urceolus 14, and urceolus 14 welds with inner core 13 after flanging in top.
Spiral pipe 16 and fused salt heat-conducting medium is provided with in described upcast chuck 12, the described space of fused salt heat conducting medium filling between upcast chuck 12 and spiral pipe 16, the fused salt heat-conducting medium in described upcast chuck 12 is the Molten Binary Salts be made up of SODIUMNITRATE+saltpetre or the ternary molten salt be made up of saltpetre+Sodium Nitrite+SODIUMNITRATE.
