The water cooler is composed of combined water pipes.
The calcining electrode is a graphite electrode.
The wall of the furnace body is made of high-temperature-resistant non-metallic materials.
The working process is as follows:
adding a petroleum coke raw material into a furnace body from a petroleum coke inlet, switching on a calcining power supply to heat the petroleum coke, calcining the petroleum coke, gradually sinking the petroleum coke under the action of gravity, continuously increasing the calcining temperature along with the sinking until the petroleum coke is calcined into graphite carbon, dropping the graphite carbon from a graphite carbon feed opening to a graphite carbon outlet, cooling the graphite carbon by a water cooler, and taking out the graphite carbon to obtain a graphite carbon product.
The technical principle is as follows:
the petroleum coke is calcined by an electrode to discharge gas to form graphite carbon.
The gas is harmful gas overflowed from incomplete calcination of the petroleum coke, sulfide is oxidized and is discharged through a calcined gas discharge port, so that the petroleum coke is completely carbonized to form finished product graphite carbon with high carbon content and less impurity gas. In general, due to temperature distribution, the central graphite is completely carbonized, petroleum coke close to the furnace body wall is affected by low temperature to form a rim charge, the petroleum coke of the central material is completely carbonized to form a qualified product, while the petroleum coke of the rim charge is not completely carbonized to form an inferior product, and the qualified product is used as a non-important product.
