Abstract

The invention relates to the field of waste treatment, in particular to a method for treating high-calorific-value oil sludge by a cement clinker device, which comprises the following steps of: removing moisture in sludge by using high-temperature tail gas of a cement kiln in a high-speed injection manner, and mixing the sludge with pulverized coal to serve as fuel of the cement kiln; and mixing the incinerated waste residue with auxiliary materials such as clay, and conducting calcining under the action of a plant-based foaming agent to obtain a foamed brick. According to the method, heat of high-temperature tail gas generated by the cement kiln is not wasted, energy can be provided for operation of the cement kiln, the burnt tail gas is completely utilized and made into the foamed brick, and resource utilization of the high-calorific-value sludge is completely achieved. According to the method, special treatment equipment does not need to be designed for treating the high-calorific-value sludge, the treatment process is synergistically completed by depending on the cement kiln, the treatment cost is low, the efficiency is high, the resource utilization rate is high, and the method is a method for circularly and economically treating the high-heat oil-containing sludge.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to a method for a cement clinker plant to dispose of high calorific value sludge. Background technique [0002] The discovery and application of petroleum has greatly changed human life. However, in the process of exploiting crude oil, a large amount of oily sludge is formed by the sediment mixed in the crude oil and the deposition of heavy components. The oily sludge has high oil content and composition. Changes greatly, and contains a certain amount of heavy metal ions, making it pollute human life, health and the environment. Therefore, how to effectively deal with oily sludge has become an important environmental protection issue faced by major oilfield companies. [0003] CN112047612A relates to an oily sludge separation device. The method mainly solves the problem that the existing separation process has low efficiency and can only complete two-phase separation. It is charact...
