Description
Technical field
The present invention relates to a kind of charcoal element can-type calcine furnace.
Background technology
At present domestic aluminium cathode goods, graphite electrode, carbon resistance rod, carburant, titanium smelting etc. all need use after-smithing petroleum coke.Above-mentioned raw petroleum coke calcination process is substantially identical, requires to be heated to 1250-1300 DEG C, makes it remove moisture, fugitive constituent, improves real density and mechanical strength, reduces resistivity.Calcining main equipment has rotary kiln, pot type burner.Can-type calcine furnace adopts indirect, and petroleum coke does not directly contact scorching hot flue gas, and the oxidization burning loss of calcination process is 4-5%, and the quality of calcined coke is better than employing calcined by rotary kiln.Require more and more tighter today at low-carbon economy, can-type calcine furnace has certain superiority.
But there is following problem in can-type calcine furnace:
1, along with withdrawal rate strengthens and fugitive constituent increases, often there is the situation of fire path temperature superelevation, thus affect the life-span.
2, to the bad adaptability of raw material.
3, operating environment is poor, and process control not easily realizes automation.
Summary of the invention
The technical problem to be solved in the present invention: a kind of new can-type calcine furnace version is provided, easily exceeds standard with the fire path temperature solved existing for existing can-type calcine furnace, to problems such as adaptability to raw material difference and not easy operation controls.
Technical solution of the present invention:
Configuration of the present invention comprises tank body, quirk, charging aperture, air preheat road, water-cooled funnel and discharge mechanism, and exterior combustion chamber is communicated with tank body, air preheat road, quirk respectively by fugitive constituent communication channel, air communication road, flue gas communication channel; Collect flue one end and connect quirk end, the other end connects outside flue gas connector.
Exterior combustion chamber is communicated with by being communicated with flue with collecting between flue, connects cigarette channel and is provided with control valve.
Exterior combustion chamber is provided with fuel and adds valve.
Collect flue and be provided with smoke flow control valve, smoke flow control valve is controlled by the temperature thermocouple being located at quirk the 4th layer.
Air preheat road is provided with intake valve.
Quirk has 10 layers.
Beneficial effect of the present invention:
1, fugitive constituent exterior combustion chamber is set, fugitive constituent in stove is put in stove quirk and burns outward, fire path temperature is reduced, improve the life-span of pot type burner quirk and then improve the life-span of whole stove.
2, can add by intake valve and fuel the intensity that valve controls exterior combustion chamber combustion, strengthen the adaptability to the fugitive constituent in raw material raw petroleum coke, moisture.
3, control the temperature in quirk by controlling flue gas flow in quirk, and by unbalanced flue gas by each smoke valve with collect flue and be connected, make the temperature control of whole stove simply, operating process also becomes simple.
4, by temperature in quirk and the closed-loop control collecting flue gas flow in flue, can realize automatic control, control accuracy is high.
5, the quirk number of plies of pot type burner is increased to 10 layers by common 8 layers, to improve the production capacity of stove.
accompanying drawing illustrates:
Fig. 1 is that A of the present invention is to structural representation;
Fig. 2 is that B of the present invention is to structural representation;
Fig. 3 is that C of the present invention is to structural representation.
detailed description of the invention:
As Fig. 3, the present embodiment forms by organizing tank body 19 in tandem, and before and after often organizing tank body 19, both sides are provided with quirk 6, and quirk 6 has 10 layers.Tank body 19 side is provided with exterior combustion chamber 5, is communicated with between exterior combustion chamber 5 with tank body 19 by fugitive constituent communication channel 3, is communicated with by air communication road 15 with between air preheat road 17, is connected by flue gas communication channel 4 with quirk 6; Quirk 6 end with collect flue 11 and be connected, collect flue 11 end and be provided with outside flue gas connector 12 and be connected with outside smoke evacuation system.Exterior combustion chamber 5 is communicated with by being communicated with flue 7 with collecting between flue 11, is communicated with flue 7 and is provided with control valve 8.Exterior combustion chamber 5 is provided with fuel and adds valve 14.Collect flue 11 and be provided with smoke flow control valve 10, smoke flow control valve 10 is controlled by the temperature thermocouple 9 being located at quirk 6 the 4th layer.Air preheat road 17 is provided with intake valve 16.
Concrete operations mode is as follows:
Tank body 19 is entered by the charging aperture 1 being positioned at stove top by the raw petroleum coke calcined, for ensureing that the fugitive constituent at body of heater top is discharged unobstructed, charging enters into certain depth in tank body 19, by the raw petroleum coke calcined by gravity mode progressively by tank body 19, progressively be heated to temperature needed for calcine technology by the heat smoke of the quirk 6 being positioned at tank body 19 both sides by the mode of indirect heat transfer, the material calcined is discharged by discharge mechanism 18 after being cooled with water-cooled funnel 2 by the air preheat road 17 of bottom again.
The fugitive constituent produced in raw petroleum coke heating process rises to the space of the formation between tank body 19 top and raw petroleum coke, import in outer cylinder 5 by fugitive constituent communication channel 3, after air needed for burning enters air preheat road 17 preheating by the air inlet valve 16 of regulating flow quantity, exterior combustion chamber 5 is entered again along air communication road 15, preheated air and fugitive constituent combustion outer room 5 combustion, the flue gas produced imports in the quirk 6 of pot type burner by flue gas communication channel 4, the flue gas being positioned at quirk 6 sequentially passes through each layer quirk, quirk 6 is increased to 10 layers by original 8 layers, output can be improved.Being entered by smoke flow control valve 10 quirk 6 the 10th layer collects in flue 11, temperature thermocouple 9 is set in the 4th layer of quirk 6 to control smoke flow control valve 10, make the flue-gas temperature in each quirk remain in the temperature range of technological requirement, make operating process greatly simplify and greatly improve control accuracy.
When in raw petroleum coke, the amount of fugitive constituent is too much, flue gas superfluous in exterior combustion chamber 5 is entered by connection flue 7 and collects in flue 11, and the flow of flue gas is controlled by control valve 8; When deal of volatilizing in raw petroleum coke is very few, add by fuel the deficiency that valve 14 supplements whole system heat; Then utilize fuel to add valve 14 in pot type burner initial start stage to add fuel combustion outer room 5 combustion and be provided as the temperature required flue gas of pot type burner baker.Whole operating process is simple, is convenient to control.
The flue gas of whole system derives by being positioned at the outside flue gas connector 12 collected on flue 11.
