Application of SINOKLE Coalescing Pressure Oil Removers in Oily Wastewater Treatment
In industrial production, the treatment of oily wastewater has always been an important challenge in the environmental protection field. This type of wastewater features uneven oil-water mixing, small oil droplet size, high emulsification and complex composition; traditional treatment methods often face problems such as low removal efficiency, high treatment costs and complex operation. Addressing these industry pain points, SINOKLE has developed a high-efficiency coalescing pressure oil remover, providing a brand-new solution for oily wastewater treatment through technological innovation.
Technical principle and innovative design
SINOKLE's high-efficiency coalescing pressure oil remover adopts the coalescence (coarse granulation) principle and the shallow pool principle combined with CFD flow field optimization technology, integrating cyclonic pre-separation, high-efficiency coalescing filler and an automatic sand-flushing system to form a complete treatment system. The interior of the equipment consists of an inlet pre-separation zone, a primary separation zone and a main separation zone; a specially designed cyclonic separation device achieves preliminary separation of the oil droplets, which then undergo deep treatment through coalescing fillers of different specifications.
Internal structure diagram of the coalescing pressure oil remover
The innovation of this equipment lies in its full-flow-field CFD optimized design: computer simulation optimizes the internal flow field of the separator, keeping the internal flow pattern quickly stable and maintaining laminar flow, avoiding short-circuit flows and circulating flows.
The patented coalescing filler adopts a special fluid structure design with a large specific surface area and high separation efficiency; it uses fine local fluid actions to increase the probability of collision and contact, accelerating the coalescence of dispersed oil droplets and shortening the separation time.
Outstanding technical performance indicators
SINOKLE's coalescing pressure oil remover performs outstandingly in its technical parameters: the single-stage oil removal efficiency exceeds 90%, and the minimum treatable oil droplet size is 30 um or below. Compared with traditional equipment, the footprint is reduced by 30% and energy consumption by 40%.
The equipment adopts a fully enclosed, pressurized automatic operation mode and is equipped with a PLC automatic monitoring system, achieving precise liquid level control and automatic backwashing. The specially designed sand-flushing and desilting device effectively prevents filler clogging, ensures long-term stable operation, and achieves a service life of more than 15 years.
Wide industry application cases
In the petrochemical field, SINOKLE's coalescing pressure oil remover has been successfully applied in many large projects. A circulating water oil removal project at an oil refinery in Uzbekistan adopted two sets of equipment with a total treatment capacity of up to 17,000 m3/d, demonstrating the equipment's large-scale treatment capability.
The equipment also performs excellently in treating high-oil-content wastewater. In a petrochemical desalting wastewater treatment project, the influent oil content was as high as 10%-20%; after treatment, the effluent quality was good and met strict discharge standards.
Technology comparison with traditional processes
Compared with traditional oil removal technologies, SINOKLE's coalescing pressure oil remover has obvious advantages in many aspects. Traditional gravity separation relies on the oil-water density difference, with low treatment efficiency and a large footprint; the coarse granulation method requires no chemical reagents but requires a low inlet concentration; the filtration method has simple equipment but requires frequent backwashing.
SINOKLE's technology combines the advantages of multiple processes: it maintains the chemical-free characteristic of physical methods while greatly improving separation efficiency through coalescence technology. Its compact design is especially suitable for plants with tight land use, and automated operation significantly reduces labor and operating costs.
