Description
Technical field
The utility model relates to a kind of graphite carbon material electric calciner.
Background technology
Electric calciner top is charging opening, and discharge gate is positioned at the bottom.Raw material send electricity through the upper and lower electrode in getting into stove from the top loading hopper, utilizes the resistance heating of carbon raw materials self, makes raw material pass through preheating (low-temperature zone), heating (high temperature section), cooling back from top to bottom and discharges electric calciner from the bottom.In the carbon raw materials heat treatment process that does not contain fugitive constituent basically, sulphur and partial impurities are mainly gasified at hot stage more than 1700 ℃.Prior art is that venting hole is set on bell; Sulphur after the gasification and impurity need pass through the low-temperature zone material and efflux through the venting hole on the bell; Because the low-temperature zone temperature of charge is on the low side, cause most of gaseous sulfur and impurity condensation and attached on the low-temperature material, gasify once more after getting into high temperature section; Through this process of going round and beginning again of condensation of gasification-condensation-regasify-again; The continuous enrichment of sulphur in the material and impurity finally is brought in the product, causes sulphur and foreign matter content in the product to fluctuate widely.As the sulphur content of producing in the initial production can be lower than 0.02%, and As time goes on, and sulphur content even be higher than the sulphur content in the raw material reaches 5%.Cavity under the bell and furnace roof hopper are apart from weak point simultaneously, and air gets into electric calciner inside easily, and top conductive electrode and carbon raw materials are oxidized easily.
Improve the quality of products, realize not containing basically the refinery coke of fugitive constituent or the purpose that hard coal is purified, just must change the electric calciner inner lining structure.
Summary of the invention
The technical problem that the utility model will solve is: a kind of graphite carbon material electric calciner is provided; To overcome most of gaseous sulfur that prior art exists and impurity condensation and attached on the low-temperature material; Get into gasification once more after the high temperature section, through this process of going round and beginning again of condensation of gasification-condensation-regasify-again, the continuous enrichment of sulphur in the material and impurity; Finally be brought in the product, it is not enough to cause that sulphur and foreign matter content in the product fluctuates widely etc.
The utility model adopts following technical scheme: the charging opening of bell is connected with loading hopper, and upper electrode is arranged on loading hopper central authorities and inserts in the carbon raw materials under the bell, and lower electrode is arranged on the body of heater bottom; The periphery is a refractory lining below bell, is top carbon lining and bottom carbon lining within refractory lining, and the thickness of top carbon lining is greater than the thickness of bottom carbon lining, and the upper surface of top carbon lining and the lower surface of bell are fitted; In the carbon lining of top, venting hole is set, in the bell bottom annular waste air duct is set, venting hole communicates with annular waste air duct; Bell top is provided with one or more vapor pipes, and vapor pipe one end and annular waste air duct are joined, and the other end is connected with gas shaft, perhaps is connected with gas shaft through condensing surface.
Top carbon lining height 0.8 ~ 2m can be divided into 3 ~ 6 layers and build by laying bricks or stones, forms annulus by 8 ~ 10 fan-shaped carbon material building blocks for every layer, the annulus outside refractory lining that reclines, and the annulus inside diameter is identical with the internal diameter of bell charging opening.
The hole outside of venting hole is inboard concordant with the bottom carbon lining.
Form cavity by top carbon lining, bottom carbon lining and carbon raw materials.
The carbon raw materials that is used to purify is generally all through 1000 ℃ ~ 1250 ℃ thermal treatments; Its fugitive constituent and moisture content are lower, and low thermophase does not have gaseous substance basically and effluxes, and gaseous substance mainly forms at hot stage more than 1700 ℃; The utility model in time discharges out of the furnace these gaseous impuritiess (comprising sulphur) in high temperature section; Avoid its constantly circulation enrichment in stove, avoid it to get in the product, realize the requirement that carbon raw materials (refinery coke, hard coal etc.) is purified.
Gaseous impurities (comprising sulphur) in time discharges out of the furnace in high temperature section, can also avoid the material caking, avoids the bonding material in bell bottom to stop up gas exhaust duct.
The high temperature section that moves down into venting port can also reduce the air capacity that gets into electric calciner, reduces or avoid the oxidation of upper electrode and carbon raw materials.
Compared with prior art; The beneficial effect of the utility model is: gaseous sulfur of avoiding discharging in the high-temperature heat treatment process and impurity are at the stove circulating enrichment; Avoid interior material of stove so caking and influence ordinary production; Avoid condensed gaseous sulfur and impurity to get in the product, for electric calciner is produced high-purity and the graphite carbon material creates favorable conditions.The resistance to air loss of upper of furnace body is strengthened, reduce the air flow quantity that gets into electric calciner from the furnace roof hopper, reduce the oxidational losses of upper electrode and carbon raw materials.
