Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1-Fig. 3, it is structural representation of the present utility model, a kind of upright furnace coking chamber with interior air collecting chamber of the utility model, comprise coking chamber 2, described coking chamber 2 two ends and/or middle part, along coking chamber 2 height to arranging air collecting chamber 4, be provided with coal gas leadout hole 5 between coking chamber 2 and air collecting chamber 4, coking chamber 2 tops are provided with converges air flue 3 each air collecting chambers 4 of connection, and leads to upcast 8.
At the bottom of described air collecting chamber, 6 communicate with coking chamber 2.
The coal gas amount demand that described coal gas leadout hole 5 quantity produce according to destructive distillation is arranged to multilayer along high,
The air flue 3 that converges at described coking chamber 2 tops forms by stretching into coal bunker 7 near the sidewall of coking chamber 2 center positions, and another sidewall forms with laying fireproof bricks, converges the air flue 3 downward self-assembling formation openings in bottom.
Described air collecting chamber 4, coal gas leadout hole 5 and converge air flue 3 and can form with laying fireproof bricks, also can be welded with heat-resisting steel sheet and plate.
Following examples are implemented under taking technical solutions of the utility model as prerequisite, provided detailed embodiment and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is ordinary method if no special instructions.
The concrete application structure form of [embodiment 1] one of the present utility model
See Fig. 1-Fig. 3, it is the structural representation of a kind of upright furnace coking chamber embodiment with interior air collecting chamber of the utility model, comprise combustion chamber 1 and coking chamber 2 22, be provided with air collecting chamber 4 at every coking chamber 2 two ends and/or middle part, between coking chamber 2 and air collecting chamber 4, be provided with coal gas leadout hole 5, coal gas leadout hole 5 is along high to arranging 1 every 0.5～1 meter, its perforate direction and structure formation can ensure that coal gas leadout hole 5 is not blocked by descending coal charge, being conducive to again raw gas derives, and can also prevent that the coal charge in coking chamber 2 from entering air collecting chamber 4 by coal gas leadout hole 5.The height of coal gas leadout hole 5 is 40～100mm.
At the bottom of air collecting chamber, 6 is the downward opening of air collecting chamber 4, the coke powder or the coal dust that are blown in air collecting chamber 4 can be discharged in coking chamber 2 again, can not stop up air collecting chamber 4 passages.Air collecting chamber 4 and coal gas leadout hole 5 both can be built by laying bricks or stones and form with heterotypic fire brick, also can make with heat-resisting steel sheet and plate welding.
By the both sides of coking chamber 2 walls, converges air flue 3 along long to being provided with at coking chamber 2 tops, converge air flue 3 air collecting chamber at coking chamber 2 middle parts and/or two ends is connected 4 logical so that raw gas is derived through upcast 8 smoothly from one end of coking chamber 2.Converge air flue 3 and form by stretching into coal bunker 7 near the sidewall of coking chamber 2 directions, another sidewall forms with laying fireproof bricks.Converge the opening of the air flue 3 downward self-assembling formations in bottom, be both conducive to further collect the raw gas of coking chamber 2 dryer section, can prevent again tar condensing obstructing airway in air flue.
The principle of work of a kind of upright furnace coking chamber with interior air collecting chamber of the utility model: upright furnace is in the time of normal production, and feed coal packs into from coking chamber 2 top coal bins, enters in coking chamber 2 through stretching into coal bunker 7.Coking chamber 2 both sides are combustion chamber, and inflammable gas burns in the flue of combustion chamber, and the heat of generation passes to the coal charge in coking chamber 2 by furnace wall, and coal issues raw pyrolytic reaction at high temperature action, separates out volatile matter, generate semicoke simultaneously.The volatile matter generating is raw gas, interior along transverse flow at coking chamber 2, enter the air collecting chamber 4 at two ends and/or middle part through coal gas leadout hole 5, air collecting chamber 4 interior on flow, what enter coking chamber 2 tops converges air flue 3, converge in air flue 3, converge laggard enter upcast 8, export to the effuser outside stove through upcast 8, then enter gas cleaning system.Coal charge moves from top to bottom in coking chamber, and the semicoke of generation is discharged after steam is cooling continuously in bottom.
A kind of upright furnace coking chamber with interior air collecting chamber of the utility model, the raw gas that coal charge destructive distillation is produced is directly derived from the air collecting chamber 4 that is arranged on coking chamber 2 inside, gas needn't be discharged from bed of material top through the thick bed of material, reduce raw gas and separated out resistance, prevented that the furnace pressure causing because bed permeability is poor is too high.Because coal gas is directly derived from air collecting chamber 4, also reduce the amount of carrying secretly of dust in coal gas, make the tar of later stage generation cleaner.
