Abstract

The invention discloses a method and a device for microwave pyrolysis of sludge. The device for microwave pyrolysis of sludge comprises a microwave reaction device, a vapor recovery device and an oil gas recovery device in communication. The microwave reaction device comprises a microwave reaction cavity, and a first microwave generator arranged in a microwave reaction cavity enables the microwave reaction cavity to have a plurality of temperature areas in sequential temperature rise in the direction from an inlet of the microwave reaction cavity to an outlet. Microwaves serve as a heat source to substitute for a traditional heating method for microwave pyrolysis of sludge, water, pyrolysis gas and pyrolysis residues are obtained sectionally by means of sectional heating and condensation, and heat energy in a condensation process is completely used as a heat source for sludge drying, so that energy saving, environment friendly and sludge recycling are realized.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a device and method for oil field sludge treatment. Background technique [0002] In the prior art, common technical methods for oil sludge treatment mainly include landfill method, solidification method, incineration method, coking method, chemical hot washing, solvent extraction, biological treatment, brick making technology, etc. Among them, the heat treatment technology is not only conducive to improving the oil recovery rate in the sludge, but also at a higher temperature part of the heavy asphalt material can be coked into solid carbon, solidifying the heavy metals and other harmful substances contained in the sludge, and realizing the harmless treatment of the sludge. [0003] Existing heat treatment technologies are mainly divided into two types: traditional heat sources and microwaves. Traditional heat sources usually use electric heating or combustion heating, and the h...
