Abstract
The utility model relates to a pot type forging furnace for coking. The utility model is characterized in that 3-layer burning nozzles are adopted, and are uniformly arranged in the furnace. The wind enters from the bottom edge of each burning nozzles. A fire channel, a fire channel wall and a forging pot are built by high-quality bricks. Thus the forging furnace has a long high temperature area. Raw material can stay in the high temperature area for a long time. The temperature distribution is uniform; the forging temperature is high; the forging quality is good. Thus the utility model can be used for forging the needlelike coke of coal series with the real specific gravity bigger than 2.11g/cm< 3 >.
Description
The utility model relates to a kind of coking can-type calcine furnace, and it is provided with three layers of burning and chews, and is to chew wind intake from bottom from burning, the high temperature head of district, and the calcining temperature height is applicable to that the calcining true specific gravity is greater than 2.11g/cm
3Coal-based needle coke.
Needle coke has two kinds in oil system and coal measures, is the senior carbon raw materials that is used for making ultra-high power graphite electrode.Also do not calcine both at home and abroad at present the equipment of coal-based needle coke, domestic existing can-type calcine furnace is used to calcine and postpones pitch coke, burns the product true specific gravity that only at 2.05g/cm
3Below.Its reason is to adopt individual layer to burn to chew structure, burning is chewed few, limited the outer for amount of combustion gas, combustion air is parallel entering in the stove with supplying combustion gas outward in addition, and degree of mixing is poor, so the high-temperature zone is short, only be 1.9 meters, raw material is about 15 hours in the high-temperature zone residence time, and calcining temperature is low, only be 1260～1300 ℃, calcining jar and quirk wall adopt common silica brick.
In view of the foregoing, the objective of the invention is to design a kind of high temperature head of district, calcining temperature height, can calcine out true specific gravity greater than 2.11g/cm
3The can-type calcine furnace of coal-based needle coke.
For realizing this purpose, the technical measures that the utility model is taked and the positively effect of generation are: (1) is provided with at body of heater first and third, six layers of quirk place outside three layers to burn for combustion gas and chews, make the high-temperature zone prolong about 1 meter, thereby make raw material prolong nearly 10 hours in the residence time of high-temperature zone.(2) make combustion air chew the base and enter, adopt combustion air and supply the vertical blended measure of meeting of fuel outward, make the two thorough mixing from burning.Take above-mentioned two measures, improved calcining temperature widely, reach 1450～1500 ℃, must adopt load softening point just can bear this high temperature impact in calcining jar and quirk wall place for this reason greater than 1660 ℃ refractory materials.
Introduce content of the present utility model in detail below in conjunction with drawings and Examples.
Fig. 1, Fig. 2 chew the one-piece construction sectional view of can-type calcine furnace with three layers of burning for coal-based needle coke.
Fig. 3 is the vertical mixing mechanism synoptic diagram that meets with combustion gas of combustion air.
Such as Fig. 1, shown in 2, it is to be burnt by (1) ground floor to chew that coal-based needle coke is chewed can-type calcine furnace with three layers of burning, (2) second layer burns and chews, (3) the 3rd layers of burning are chewed, (4) quirk dividing plate, (5) flue wall, (6) calcining tank, (7) first volatile matter access road, (8) second volatile matter access roades, (9) air inlet passage, (10) flue outlet, (11) body of heater exterior wall, (12) body of heater base plate, (13) cooler, (14) support, (15) mixing chamber, (16) air and fuel gas mixture access road, (17) warm-up combustion-supporting air access road and (18) quirk form. First, second and third layer burning chewed (1), (2), (3) lay respectively at first and third, six layer of quirk place, first and second layer burning chewed with the 3rd layer of burning and chewed the both sides that are located at respectively body of heater, owing to establish three layers of burning and chew, connection and reasonable arrangement, institute is so that the high-temperature region prolongs about 1 meter, also make raw material prolong nearly 10 hours in the time of staying of high-temperature region, this has not only increased outer for gas quantity, and uniformity of temperature profile, improved calcining heat, burning quality also improves greatly, and totally seven on quirk dividing plate (4) consists of eight layers of quirk (18). Because the raising of calcining heat, quirk dividing plate (4), flue wall (5), calcining tank (6) all adopt load softening point greater than 1660 ℃ refractory material laying, high temperature resistant impact. First and second volatile matter access road (7), (8) are located at respectively second, four layer of quirk place (volatilization is divided into interior for combustion gas).
Air inlet passage (9) is horizontally set on furnace bottom, warm-up combustion-supporting air access road (17) is vertically set in the body of heater exterior wall (11), the mixing chamber (15) and air inlet passage (9), vertical the communicating of second volatile matter access road (8) chewed with each layer burning respectively. As shown in Figure 3, warm-up combustion-supporting air and combustion gas vertical mixing of meeting in mixing chamber (15) have been strengthened the two mixability, make calcining heat can be increased to 1450～1500 ℃.
Coal-based needle coke is chewed the gas flow process following (referring to Fig. 1) of can-type calcine furnace with three layers of burning:
After the first layer burning of lighting the first layer quirk place was chewed (1), nearly 1200 ℃ high-temp waste gas and superfluous high temperature air flowed to second layer quirk.At second layer quirk, superfluous high temperature air and the volatile matter mixed calcining of introducing from first volatile matter access road (7) are raised to more than 1450 ℃ spent air temperture.At the 3rd layer of quirk, burn the mixture combustion that the mixing section (15) chew (2) sprays into warm-up combustion-supporting air in the stove and combustion gas from the second layer after, the temperature that has guaranteed the 3rd layer of quirk is more than 1450 ℃.At the 4th layer of quirk, behind volatile matter of introducing from second volatile matter access road (8) and the warm-up combustion-supporting air mixed calcining that enters from warm-up combustion-supporting air access road (17), the temperature-stable that has guaranteed fourth, fifth layer of quirk is more than 1450 ℃.At the layer 6 quirk, chew the combustion gas and the calcining of warm-up combustion-supporting air gas mixture that the mixing section (15) of (3) sprays into from the 3rd layer of burning after, the temperature that has guaranteed the 6th, seven layer of quirk is more than 1450 ℃.At the 8th layer of quirk, the temperature of waste gas begins to reduce, and locates at flue outlet (10), and the temperature of waste gas is roughly reduced to 1000～1100 ℃.
