Abstract

The invention relates to treatment equipment and a process of oily sludge and sand. The equipment is characterized in that one side of a rotary kiln is provided with a crude oily sludge and sand inlet, a thermosetting carrier reflux port, a rotary kiln driving motor and a slag discharging port, and the other side of the rotary kiln is provided with an oil gas outlet and a thermosetting carrier discharging port; the oil gas outlet is connected with a condenser; the thermosetting carrier discharging port is communicated with a fluidized bed through a chain bucket; a cyclone separator is arranged in the fluidized bed; solid separation and regeneration of a thermosetting carrier are carried out through the cyclone separator; the cyclone separator is communicated with the rotary kiln through the thermosetting carrier reflux port; and the bottom of the fluidized bed is connected with an air blower through a pipeline. The process has the beneficial effects that in production operation, oil and sludge separation is carried out by utilizing a pyrolysis method and special equipment; separated and recovered oil is qualified oil through process steps such as impurity removal and the like in the special equipment, the product has good social benefits, and no secondary pollution is generated; and the oil content in sludge obtained by purification and separation is not more than 0.03%.

Description

1. Technical field: [0001] The invention relates to an oil sludge sand treatment equipment and process, in particular to an oil sludge sand treatment device and process. 2. Background technology: [0002] At present, the oil sludge sand treatment in existing oil fields generally has the following methods: [0003] (1) Solvent extraction [0004] The extraction method is to use the principle of "like dissolves like" to select a suitable organic solvent as the extraction agent. After the organic waste is extracted from the sludge by the solvent, the solvent is separated from the mixture by distillation and recycled. The recovered crude oil is used Yu back to practice. [0005] The U.S. patent proposes a process of solvent extraction and oxidation treatment of oily sludge. A light hydrocarbon is added to the sludge as an extractant. After extraction, the oil and most of the organic matter are removed, but some polymeric aromatic hydrocarbons are still contained. The residual...
