Recycling process of petroleum coke calcination dust collection powder
The invention discloses a petroleum coke calcination dust collection powder recycling process, which belongs to the technical field of petroleum coke calcination, and comprises the steps of pretreatment, mixing, compression molding, drying, sintering, crushing and recycling. The pretreatment comprises the following steps: adding the petroleum coke calcined dust collection powder, cane sugar and water into a mixing kettle, and stirring to obtain a petroleum coke calcined dust collection powder mixed solution; phenolic resin and absolute ethyl alcohol are added into a mixing kettle and stirred, and a phenolic resin solution is obtained; adding the petroleum coke calcination dust collection powder mixed solution and a phenolic resin solution into a mixing kettle, stirring, transferring into a reaction kettle, sealing the reaction kettle, keeping at 180-190 DEG C for 8-10 hours, opening the reaction kettle, filtering, cleaning, and drying filter residues; by means of the process, the petroleum coke calcination dust collection powder can be recycled, the mixing difficulty is small when the petroleum coke calcination dust collection powder is mixed with the high-sulfur petroleum coke, pulverization is not prone to occurring in the crushing process after sintering, and the true density of a recycled product cannot be reduced.
本发明公开了一种石油焦煅烧收尘粉再利用工艺，属于石油焦煅烧技术领域，所述工艺包括：预处理，混合，压制成型，干燥，烧结，破碎，再利用；所述预处理，将石油焦煅烧收尘粉、蔗糖、水加入混合釜中，搅拌，得到石油焦煅烧收尘粉混合液；将酚醛树脂、无水乙醇加入混合釜中，搅拌，得到酚醛树脂溶液；将石油焦煅烧收尘粉混合液与酚醛树脂溶液加入混合釜中，搅拌，转入反应釜中，将反应釜密闭后，在180‑190℃下保持8‑10h，打开反应釜，过滤，清洗、烘干滤渣；本发明的工艺能够实现对石油焦煅烧收尘粉的再利用，与高硫石油焦混合时的混合难度小，在烧结后破碎过程中不易粉化，且不会导致再利用产品的真密度下降。
