Collaborative resourceful treatment method and treatment system for oil-based rock debris and kitchen biogas residues

Abstract

The invention relates to the field of environment-friendly resource utilization, and discloses a collaborative resourceful treatment method and system for oil-based rock debris and kitchen biogas residues. According to the method, the oil-based rock debris is subjected to solid-liquid separation, drying and fine crushing to obtain powder, then the kitchen waste is subjected to screening and solid-liquid separation, obtained grease and solid-phase residues are mixed with the oil-based rock debris powder according to a certain proportion, and finally the mixture is dried, formed and cut into blocks to be made into the solid fuel. According to the treatment system, the oil-based rock debris and the kitchen biogas residues are treated respectively, reasonable combination of the oil-based rock debris and the kitchen biogas residues is achieved, the problem that the oil-based rock debris and the kitchen biogas residues are difficult to treat is well solved, the effects of reduction, harmlessness and recycling can be achieved for the oil-based rock debris and the kitchen biogas residues, the environmental benefits and the economic benefits are obvious, and the method is suitable for industrial production. Not only is the environmental risk of the oil-based rock debris greatly reduced, but also the recycling value of the kitchen biogas residues and the oil-based rock is further improved, and a contribution is made to reduction of carbon emission in China.

Description

technical field

[0001] The invention relates to the field of environmental protection resource utilization, in particular to a method and a processing system for the co-resource processing of oil-based rock chips and kitchen biogas residues. Background technique

[0002] Oil-based cuttings are a kind of oily solid waste generated when oil-based drilling fluid is used to open up oil and gas "channels". Emissions will cause serious pollution to the environment. At present, the main technical methods for the treatment of oil-based cuttings include solidification and safe landfill method, drying technology, physicochemical separation method, incineration method, high temperature thermal cracking, and biodegradation technology. Due to the high cost of the above-mentioned processing technologies and the low degree of resource utilization, most exploration companies are very troubled by the problem of oil-based cuttings.

[0003] Kitchen waste refers to the garbage generated in t...
