Abstract

The invention discloses an oily sludge treatment system based on a three-section rotary kiln. The system is characterized by comprising a fluidized bed, the outlet end of the fluidized bed is connected with a cyclone separator through a pipeline; the air outlet end of the cyclone separator communicates with the inner cavity of a heat transfer jacket through a pipeline; the ash discharge end of thecyclone separator is connected with the inlet end of the three-section rotary kiln through a pipeline; the three-section rotary kiln is sequentially divided into a mixing section, a heat transfer section and a combustion section from an inlet end to an outlet end of the three-section rotary kiln. The heat transfer jacket is arranged on the outer side of the heat transfer section; a combustion jacket is further arranged on the outer side of the combustion section; a feeding spiral conveyor is also arranged in the three-section rotary kiln; the outlet end of the three-section rotary kiln is connected with an oil-gas separation condenser through a pipeline, an oil outlet in the bottom end of the oil-gas separation condenser is connected with an oil storage tank located below the oil-gas separation condenser through a pipeline, and a gas outlet in the top end of the oil-gas separation condenser is connected with a gas storage tank through a pipeline with a gas pump.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to an oily sludge treatment system based on a three-stage rotary kiln. Background technique [0002] Oily sludge is a mixture of various forms formed by mixing crude oil or refined oil into soil or other media. Because the oil in it may cause environmental pollution, it cannot be discharged directly. It is one of the important pollutants in the petrochemical industry. Oily sludge contains a large amount of toxic and harmful organic substances, which are easily absorbed by plants and endanger the health of animals and humans along the food chain. The high viscosity and poor biodegradability of oily sludge cannot be solved by ordinary solid waste treatment and disposal methods. If the oily sludge cannot be effectively and thoroughly treated, it will cause great harm to the environment and have a far-reaching impact. There are many treatment methods for oily sludge, including incinera...
