Rotary kiln for calcining refinery coke

Abstract

The invention discloses a petroleum coke calcining rotary kiln, which comprises a rotary kiln(9); an insert plate valve(1) is arranged below a calcining front chamber; an adhesive tape constant feeder(2) is arranged below the insert plate valve, and an adhesive tape conveyer(3) is arranged behind the adhesive tape constant feeder (2) and connected with the rotary kiln(9) by an oblique cutting feed tipping tube of an electric insert plate valve(6); the tail part of the rotary kiln(9) is connected with a dust deposition chamber(8), and the head part of the rotary kiln(9) is connected with a cooling machine(16) and provided with a burner nozzle(13) and a burner nozzle hanger(14); the petroleum coke calcining rotary kiln is also provided with a one-time combustion fan(10) matched with the burner nozzle; and a dust-containing waste gas processing system(15) is arranged beside the cooling machine(16). The petroleum coke calcining rotary kiln has the advantages of improving the unit volume capacity, greatly enhancing comprehensive utilization of waste heat and adaptability of other calcining materials such as needle coke, anthracite and the like, reducing burning loss of charcoal, saving raw materials and energy, improving automatization level and reducing labor intensity of a worker.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a rotary kiln for calcining petroleum coke in the production of aluminum anodes. Background technique [0002] With the continuous development of the carbon anode industry for aluminum and other carbon industries, the production scale of a single production line continues to expand, and the original production process and production equipment also need to be constantly updated, improved and increased output. As one of the important processes in the carbon process, calcination , the main equipment used in the rotary kiln should also adapt to the new process requirements. As an important part of carbon industrial production - calcination, most of the production processes use rotary kiln as the main equipment. At present, although the rotary kiln, the mainstream calcining equipment used in the domestic carbon industry, has been greatly improved in the continuous operation time due to the accumulati...

AI Technical Summary

Problems solved by technology

At present, although the rotary kiln, the mainstream calcining equipment used in various domestic carbon industries, has greatly improved the continuous operation time due to the long-term accumulation of experience in production operations, its main technical level, such as the capacity per unit volume, is not suitable for other calcined raw materials such as The adaptability of needle coke and anthracite has not been greatly improved; the common problems of existing rotary kilns are: low equipment operation rate, small production capacity, high carbon burning loss, low actual yield, low thermal efficiency, physical and chemical problems of calcined coke Poor indicators and low level of automation
