After the low-temperature dry distillation furnace is adopted, the structure is simplified, the leakage failure is eliminated, and the heat loss is reduced. The temperature of the dry distillation chamber is maintained to be stable, so that the safety and the service performance of the product can be improved. The heat utilization is increased to the utmost extent, and the heat transfer effect is improved.
Description
Technical field
The utility model belongs to a kind of rotary dry distillation kiln, particularly a kind of solid small particles raw material low-temperature pyrolysis stove.
Background technology
In chemical industry, originally take resinous shale as raw material, by the destructive distillation rotary kiln of distillation process produce hydrocarbons, it in its structure, is the resinous shale material delivery heat pipe arranging in rotating body of heater along axis, between heat pipe and the inwall of body of heater, there is counter-flowing path, and combustion chamber and destructive distillation chamber are set in body of heater, the destructive distillation pipe that destructive distillation chamber connects is straight-through outside.The oil gas that resinous shale produces after destructive distillation is discharged by destructive distillation pipe.The deficiency that the rotary dry distillation kiln of this structure exists is: 1, complex structure, cost is high, needs to carry out dynamic seal between destructive distillation pipe and external module, easily produces and reveals.2, oil shale waste slag refluxes unstablely, destructive distillation chamber is obtained when many when hot few, is unfavorable for that destructive distillation chambers temp is continual and steady, is also unfavorable for destructive distillation chamber and combustion chamber gas mutually isolated separately.
Utility model content
The purpose of this utility model is to provide a kind of solid small particles raw material low-temperature pyrolysis stove, and simplified construction is removed destructive distillation pipe, eliminates the dynamic seal between itself and external module, gets rid of and reveals fault.Destructive distillation chambers temp is continual and steady, improves the security of product.Reduce costs, improve the use properties of product.
The purpose of this utility model is achieved by the following technical solution: it comprises and is provided with feeding warehouse, revolution body of heater, the material delivery heat pipe of opening for feed and carbonization gas outlet, destructive distillation chamber and the combustion chamber of sealing, it is characterized in that: the tail end of material delivery heat pipe is communicated with destructive distillation chamber, between rear portion, destructive distillation chamber and rear portion, combustion chamber, be communicated with spiral and transport pipe, destructive distillation chamber anterior with front portion, combustion chamber between be communicated with spiral heat carrier feed back pipe.
Heat pipe is uniform arranges 4-6 for the delivery of above-mentioned material.
Positively effect of the present utility model: 1, simplified construction, remove destructive distillation pipe, eliminate the dynamic seal between itself and external module, get rid of and reveal fault, reduced calorific loss simultaneously.2, destructive distillation chamber and combustion chamber gas mutually isolated separately, makes destructive distillation chambers temp continual and steady, improves the security of product.Reduce costs, improve the use properties of product.3, carbonization gas backheat material, second stage employ, has increased Btu utilization to greatest extent.4, in material delivery heat pipe, add atmospheric occupancy volume, increase heat-transfer effect.5, material is " boiling " state in material delivery heat pipe, is more conducive to conduct heat.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3, the 4th, spiral feed back pipe and raw material heat carrier spiral transport pipe two ends and are connected to tangential connection diagram with revolution inboard wall of furnace body.
Fig. 5 is the junction fill process schematic diagram that body of heater rotation Raw heat carrier spiral transports pipe.
Embodiment
See Fig. 1-5, concrete structure is as follows: revolution body of heater arranges furnace wall 8 and inwall 7, head end end be provided with opening for feed 13 and carbonization gas outlet 11 feeding warehouse 10, it (is prior art that the terminal pad of head end and the feeding warehouse 10 of revolution body of heater by dynamic seal is connected, not shown), at tail end, be provided with air intlet 2 and the combustion-supporting mouth 1 of nitrogen; In revolution body of heater, be set up in parallel vertically uniform 4-6 root material delivery heat pipe 9, in heat pipe 9, there is conducting strip, the blue carbon solid material of small-particle entering from feeding warehouse enters in four material delivery heat pipes 9, and material delivers between heat pipe 9 and revolution inboard wall of furnace body 7 and between tube and tube, is exhaust gases passes; The destructive distillation chamber 6 of the tail end communication seals of four material delivery heat pipes; Between 6 rear portions, destructive distillation chamber and 4 rear portions, combustion chamber, be communicated with spiral and transport pipe 3, destructive distillation chamber 6 anterior with 4 front portions, combustion chamber between be communicated with spiral heat carrier feed back pipe 5.
See Fig. 3,4, spiral transports pipe 3 and spiral heat carrier feed back pipe 5 is tangential connection with junction 3-2,3-1,5-1, the 5-2 of revolution inboard wall of furnace body 7.
Principle of work:
From opening for feed 13, drop into granular blue carbon material, revolution body of heater is in rotary course, and blue carbon material moves ahead in four material delivery heat pipes 9, has the retrograde space of carbonization gas in heat pipe 9.Blue carbon material reaches behind destructive distillation chamber, and because the quality of inertia effect and material determines, material is the lower left in cylindrical shell (from the left end of Fig. 1) all the time, and both dash areas in Fig. 5 a accounts for the 12-15% of overall volume rate.When raw material is along with housing clockwise rotates, when spiral transports pipe 3 junction 3-1 and forwards low level to, if Fig. 5 c, d, e, f are feed state figure, material enters into spiral by inertia effect and transports pipe 3, along with the rotation of housing, through spiral, transport pipe 3 and enter into combustion chamber 4.When forwarding Fig. 5 g to, just stop charging.As while being clockwise to Fig. 5 h, start again a circulation.While forwarding housing below to for the junction 5-2 of spiral heat carrier feed back pipe 5, also can enter sub-fraction material simultaneously, but this part material can be parked in feed back pipe, mix and get back to destructive distillation chamber 6 with 1/3 the feed back (800 degree) of the total amount of returning from combustion chamber 4 afterwards.At this moment the material in spiral heat carrier feed back pipe 5 can play the effect of a material envelope, and combustion chamber 4 and destructive distillation chamber 6 are separated completely, has avoided the mixing of gas and material, has guaranteed that the stable of combustion chamber and destructive distillation chamber carries out.The material powder of 800 degree of returning from combustion chamber in spiral heat carrier feed back pipe 5 mixes destructive distillation chamber with the raw material of 500 degree, makes to reach 600 degree in destructive distillation chamber, reaches the object of material destructive distillation.
Blue carbon or resinous shale that the material that the utility model adopts is fine granularity.
