Abstract

The invention discloses a novel carbon calcining furnace, which comprises a furnace body (2), and is characterized in that: a heating bin (7) is arranged in the furnace body (2), and adopts a carbon liner; an upper heating connecting ring (8) and a lower heating connecting ring (22) are arranged in the heating bin (7); a heating body (19) is arranged between the upper heating connecting ring (8) and the lower heating connecting ring (22); and the upper heating connecting ring (8) and the lower heating connecting ring (22) are respectively connected with a graphite cross beam (17). According to the calcining furnace, the furnace body adopts the carbon liner, so that the corrosion of fluorine can be effectively prevented, and the furnace body is high temperature resistant; and the furnace body is used for preheating materials to be heat through a preheating bin, so that the heat energy is saved. The calcining furnace can be used for calcining, electrolytic aluminium wastes, low-grade inferior graphite, coal, petroleum coke and other carbon materials at high temperature, for desulfurizating and devolatilizing, so that the quality of the carbon materials is improved.

Description

technical field [0001] The invention relates to a novel carbon calciner, in particular to a novel carbon calciner capable of rapidly removing fluorine and sulfur. Background technique [0002] Calcination is an important process in the production of carbon products. The quality of calcination has a great influence on the quality of products and the technical indicators of subsequent processes, and is an important guarantee for the production of qualified carbon products. The calcination process can make the coke undergo complex physical and chemical changes, discharge volatile matter, moisture, increase density and conductivity, and at the same time the coke structure shrinks, the microstructure is regularized, the structural defects are compensated, and high-quality calcined coke is produced. At present, the mature carbon calcination system such as petroleum coke calcination system can meet the requirement of short calcination cycle. Due to cooling and poor corrosion resist...
