Method for preparing green artificial aggregate pellets from residues produced during oil sludge pyrolysis
The invention discloses a method for preparing artificial aggregate pellets from residues produced during oil sludge pyrolysis. The method comprises the following steps of: weighing a certain amount of residues produced during oil sludge pyrolysis, adding a certain amount of rice bran and husk into the weighed residues produced during oil sludge pyrolysis, fully and uniformly mixing the materials by stirring, adding water into the fully and uniformly mixed materials, conducting mechanical stirring, starting a disc pelletizer, adding the mixed materials into the disc pelletizer to serve as master batch pellets, adding water into the master batch pellets, adding materials into the master batch pellets to promote the growth of the master batch pellets, rolling the pellets in a disc for a period of time, and stopping water adding and material adding when the master batch pellets grow to a proper particle size, thereby obtaining the green artificial aggregate pellets. The prepared pellets can be used for preparing artificial aggregate through later sintering. The preparation method has the advantages that the technology is simple and easy to implement, an adhesive is not needed, and the prepared green artificial aggregate pellets are high in strength and large in binding power.
本发明公开了一种油泥热解残渣制备人造骨料生球的方法，包括以下步骤：称取一定量的油泥热解残渣，向称取的油泥热解残渣中加入一定量的统糠，再经过搅拌将物料充分混匀，向充分混匀物种中加水并进行机械搅拌，启动圆盘造球机并向圆盘造球机中加入混合后物料作为母料球，向母球打水、加料促进母球生长，球团在圆盘内滚压一段时间，当母球长到合适粒径时停止打水和加料，即制得人造骨料生球。制备的球粒可用于后期焙烧制备人造骨料，本发明技术简单易行，无需粘接剂，制备的人造骨料生球强度高，球团粘结力大。
