Description
Technical field
The utility model relates to chemical industry coking field, particularly relates to and all presses internal heat type Low-temperature carbonization stove.
Background technology
The upright external-heat Low-temperature carbonization stove (raw coal is the blue charcoal of output and raw gas after gas-fired heating) that calm and peaceful Coal Chemical Industry company limited of (Shan Mei group) Shenmu County now uses Low-temperature carbonization stove (blue charcoal stove) to design for Anshan Thermal Energy Inst., blue charcoal 7.5 ten thousand tons is produced in design per year, actual annual output 6.5 ten thousand tons.Wasted heat, heats is bad.
Utility model content
The object of utility model: in order to provide all pressures internal heat type Low-temperature carbonization stove of better effects if, specific purposes are shown in multiple substantial technological effects of concrete implementation section.
In order to reach as above object, the utility model takes following technical scheme:
All press internal heat type Low-temperature carbonization stove, it is characterized in that, comprise coking chamber, described coking chamber comprises multiple chamber separated, its top UNICOM, also comprise the air inlet lines 7 and coal gas inlet pipe that penetrate from middle part, the two separates multiple subchannel separately, and be blended in the quirk be distributed in the middle part of coking chamber, described quirk comprises multiple and passes coking chamber, comprise coal inlet above described coking chamber, below comprises coke outlet.
The further technical scheme of the utility model is there is coke discharge box below described coke outlet.
The further technical scheme of the utility model is, described coal inlet comprises multiple, the number of itself and coking chamber and position corresponding.
The further technical scheme of the utility model is, comprises a horizontally disposed conveyor above described coking chamber.
Adopt the utility model of as above technical scheme, have following beneficial effect relative to prior art: blue carbon yield increases by more than 15% after above technological transformation, producing coal tolerance increases by more than 20%, and operation simplifies more.
Accompanying drawing explanation
In order to further illustrate the utility model, be described further below in conjunction with accompanying drawing:
Fig. 1 is utility model structural representation;
Wherein: 1. conveyor; 2. coal inlet; 3. divider wall; 4. coking chamber; 5. coal gas inlet pipe; 6. coke discharge box; 7. air inlet lines; 8. coke outlet; 9. quirk.
Embodiment
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
All press internal heat type Low-temperature carbonization stove, it is characterized in that, comprise coking chamber 4, described coking chamber 4 comprises multiple chamber separated, its top UNICOM, also comprise the air inlet lines 7 and coal gas inlet pipe 5 that penetrate from middle part, the two separates multiple subchannel separately, and be blended in the quirk be distributed in the middle part of coking chamber 4, described quirk comprises multiple and passes coking chamber, comprise coal inlet above described coking chamber, below comprises coke outlet.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are for one of any as follows: A. charring furnace inlet manifold strengthens more than 100%, transform middle part individual layer air inlet as by middle part, the double-deck air inlet in bottom; B. charring furnace is made up of four coking chambers, independent separately, each coking chamber conducting after the transformation of charring furnace internal upper part, pressure uniform.
After technological transformation, blue carbon yield increases by more than 15%, and producing coal tolerance increases by more than 20%, at present by still having room for promotion after operation optimization.
As further expansion, inner quirk size can also be reduced, former enter retort gas in quirk combustion, raw coal in indirect heating coking chamber.After transformation, coal gas does not catch fire at quirk and directly burns at the outer coking chamber of quirk;
Can also charring furnace inner top be installed additional a point device of air in addition, ensure the raw coal got off in top and go out the gas flow distribution of charring furnace even.
Described all pipelines can be overlapped in coking chamber as support.
Coke discharge box 6 is had below described coke outlet.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows, and it is medium to be discharged that the product that coking completes can put into coke discharge box 6.
Described coal inlet comprises multiple, the number of itself and coking chamber 4 and position corresponding.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows, and the number of top is corresponding, therefore, it is possible to multiple inlet feed, material is evenly distributed.
A horizontally disposed conveyor 1 is comprised above described coking chamber.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows, provide at least a kind of mechanism of charging, but are not limited to above structure and mode, such as, can multiple scrapper conveyor charging, the opening for feed of each corresponding below.
In a creative way, each effect above independently exists, and can also complete the combination of the above results with a nested structure.
It is clear that the technique effect that above structure realizes realizes, if do not consider the technical scheme of adding, this patent title can also be a kind of coking furnace.
Certainly, coking technology belongs to prior art.
It should be noted that, multiple schemes that this patent provides comprise general planning own, separate, mutually do not restrict, but it also can combine when not conflicting mutually, reaching multiple effect and jointly realizing.
Expansion as nonessential: the step based on the amendment of original stove is:
1, remove whole charring furnace and enter coal gas, air line, house steward, arm enters coal gas, air line is removed, middle part coal gas.Air line is newly joined.
2, remove whole quirk in charring furnace, again build quirk by laying bricks or stones, quirk width reduces, and corresponding coking chamber volume increases.
3, be divided into 4 coking chambers by three partition walls in charring furnace, by each coking chamber of conducting after three partition walls reduction height, make charring furnace internal pressure consistent.
4, in charring furnace, each coking chamber top installs a point gas cloth device for coal additional.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
