With the development of science and technology and people's attention to environmental protection, drying decanter centrifuge in the waste drill cuttings treatment systems more and more, according to the drying centrifuge processing capabilities, which are mainly used in petroleum weather drilling, shale gas development bed methane development, environmental protection and other aspects of treatment.
Decanter centrifuges http://www.kosungroup.com/products/solids-control-equipment/dc-series-de... by two motor-driven, the main motor driven by rotation of the belt drum and differential housing after auxiliary motor via a differential gear drive screw. This makes drum and the screw co-rotating, and has a certain differential speed. By centrifugal sedimentation principle to separate the drilling suspension, suspension from the feed auger tube through the hole in the fluid into the drum, the centrifugal force of the solid particles are pushed drum wall by auger blades push to drum small end slag discharge port, liquid overflow hole through the large end of the drum overflow. This constant cycle, in order to achieve continuous solid-liquid separation.
According to the working principle of the drilling decanter centrifuge, which can mainly be applied to solid-liquid separation, clarification upcoming muddy turbid liquid liquid separation of the larger particles to form only a small liquid particles in suspension, combined with market demand, solid control-centrifuge can mainly used in processing a large amount of mud oil, gas, shale gas, coal-bed methane drilling mud waste treatment and environmental protection in the field of sewage treatment, chemical industry, heavy metal recycling.
