Abstract

The invention discloses integrated system equipment for treating drilling oil-based slurry rock debris by a cement kiln. The integrated system equipment for treating drilling the oil-based slurry rock debris by the cement kiln comprises a drilling oil-based slurry rock debris storage integrated unit, a coarse separation integrated unit, a fine separation integrated unit, a kiln entry pretreatment integrated unit, a waste gas treatment integrated unit, a waste water treatment integrated unit and an integrated control unit. The integrated system equipment for treating drilling the oil-based slurry rock debris by the cement kiln has the advantages of equipment miniaturization, high integration level, high automation degree, little influence on a collaborative cement production system, high device operation reliability, capability of effectively controlling secondary pollution, low harmless treatment cost and high resource comprehensive utilization rate. The integrated system equipment for treating drilling the oil-based slurry rock debris by the cement kiln adopts standardized, automated, integrated and skid-mounted design, improves the collaborative automation degree of a hazardous waste treatment and cement production system, simplifies the treatment process flow, improves the treatment efficiency of hazard waste, reduces consumption of natural resources and environmental pollution, reduces hazard waste treatment operation risk and environment risk and reduces the comprehensive treatment cost.

Description

technical field [0001] The invention belongs to the technical field of hazardous waste treatment, and relates to a technical method for co-processing hazardous waste in cement kilns, in particular to a system device for co-processing drilling oil-based mud cuttings in cement kilns. Background technique [0002] Drilling oil-based mud cuttings are a kind of solid waste produced during the drilling of oil and gas resources. Because they contain a large amount of mineral oil and organic matter, direct discharge will seriously pollute the environment. They are hazardous wastes stipulated by the state. The harmless treatment of drilling oil-based mud cuttings and the comprehensive utilization of resources have become pain points and difficulties in the process of green exploitation of oil and gas resources. Various existing treatment technologies have different degrees of technical bottlenecks and deficiencies. [0003] The co-processing of drilling oil-based mud cuttings by ceme...
