Method for preparing ceramsite from petrochemical residual sludge
The invention relates to a method for preparing ceramsite from petrochemical residual sludge, and mainly solves the problem that a method for preparing ceramsite from petrochemical sludge does not exist in the prior art. The problem is solved by a technical scheme adopting the method, and in the method, water-containing sludge or dried sludge is taken as a raw material, additives such as clay or shale, a fluxing agent, a foaming agent and the like are doped, the mixture is uniformly mixed and granulated, sintering is performed for a certain period of time at a proper temperature and cooling inair is performed to obtain a sintered ceramsite product. The method can be used for recycling petrochemical residual sludge.
本发明涉及一种利用石化剩余污泥制备陶粒的方法，主要解决现有技术中尚无利用石化污泥制备陶粒的方法的问题。本发明通过采用一种利用石化剩余污泥制备陶粒的方法，以含水污泥或干化污泥为原料，掺加黏土或页岩、助熔剂、发泡剂等外加剂，混匀、造粒，在合适温度下烧结一定时间，空气中冷却，制备得到烧胀陶粒产品的技术方案较好地解决了上述问题，可用于石化剩余污泥再利用中。
