A kind of preparation method of controllable low-strength material

Abstract

The invention discloses a method for preparing a controllable low-strength material. The petrochemical sludge is crushed and placed in an arc plasma generator. After reacting at a high temperature, the residue after the reaction is collected, and the residue is mixed with the petrochemical sludge and The cement is mixed to obtain a controllable low-strength material. The preparation method of the controllable low-strength material disclosed by the present invention uses the reaction characteristics of plasma to react and gasify the organic matter and oily substances in petrochemical sludge, and collect the gasified residue as a controllable low-strength material As one of the raw materials, a new coupling circulation process of petrochemical sludge free of deep dehydration and petrochemical sludge gasification residue after plasma reaction is partially replaced by controllable low-strength material production raw materials is established, which can be prepared by combining petrochemical sludge with cement and residue Controllable low-strength materials can also treat petrochemical sludge, killing two birds with one stone, and realize the harmless and resource utilization of petrochemical sludge in the production process of controllable low-strength materials.

Description

Technical field [0001] The present invention belongs to the field of environmental engineering technology, and more particularly to a method of preparing a controlled low intensity material. Background technique [0002] Chemical plant, refinery, in the sewage treatment, the built-residue generated by the oil drum produced by the refrigerating pool, the residual active sludge produced by the biochemical pool, and the sewage regulating tank, the sewer tank and the flocculation sediments such as structures. The tanks are simply referred to as three mud, and the three mud belongs to petrochemical sludge, which contains oil, phenol, COD, sulfide and other contaminants, etc., and therefore, it cannot be discharged directly into the environment. Petrochemical sludge is extremely easy to stink in Shenchi, and has high water content, more difficult to dehydrate, and is the main object of petrochemical sludge treatment. [0003] Foreign foreign treatment methods are almost landfills prior...

AI Technical Summary

Problems solved by technology

However, the incineration method consumes a lot of energy and emits a large amount of flue gas. The more critical point is that the heat energy recovery of oil residues has not been realized, resulting in a waste of resources.
