The micro-interface degreasing equipment is a highly efficient degreasing device independently developed by our company. It is a complete system equipment designed for removing organic oil from the extraction solution during the wet process of non-ferrous metal smelting. The degreasing effect can reach 1 ppm.It has a service life of over 10 years under harsh conditions and low maintenance costs.
Before oil removal, the emulsified oil in the liquid is treated by utilizing the oleophilic and hydrophobic properties of the coalescing materials. The small oil droplets in the solution are enlarged into larger ones, and then the suspended oil in the solution is removed through gravity clarification. Subsequently, demulsification is carried out by dissolved air flotation to remove part of the emulsified oil. After oil removal by air flotation, the solution is further treated by modified fiber balls for adsorption oil removal. After fiber oil removal, it can basically meet the usage requirements of most working conditions. When the product solution has higher requirements, large-pore adsorption resins can be used to conduct deep oil removal through van der Waals attraction.
This degreasing system can be reasonably configured according to the nature and requirements of the customer’s solution. Within the most reasonable and economical investment, it can meet the customer’s degreasing accuracy requirements, and the oil content after degreasing can be stably controlled below 1 ppm at the highest level.
This demulsification system adopts physical methods for demulsification and oil removal. It does not involve chemical reactions and does not destroy the organic phase. Therefore, the majority of the organic phase can be recovered and reused, resulting in high economic benefits.
This degreasing system does not require any auxiliary materials during its operation and does not need to use compressed air continuously. It has low energy consumption and low operating cost. Compared with traditional activated carbon degreasing, the operation cost of this system is about 70% lower for the removal of tree resin.
This degreasing system is all made of corrosion-resistant materials, which have strong corrosion resistance and will not cause solution contamination. Moreover, it has a long service life.
This degreasing equipment is highly integrated. All the packing materials do not need to be removed for online processing. After setting the operating parameters according to the actual working conditions, the equipment can run stably and automatically for a long time without the need for long-term supervision and operation by personnel.
When this oil remover uses resin for deep oil removal, once the adsorption resin becomes saturated, there is no need to replace the resin. It can be used online for regenerations with liquid alkali. The residual alkali and wash water produced can be returned to the extraction system for reuse. This can achieve fully automated operation and no waste liquid is generated.

A:Our company’s developed high-efficiency resin oil removal system is primarily composed of four core components: a constant-flow fiber oil separator, resin adsorption tower, outlet precision filter, and resin regeneration system. It adopts a programmable logic controller (PLC) combined with various precision online monitoring instruments to achieve real-time control and monitoring of power equipment and operating parameters such as temperature, pressure, and flow during operation.
Preliminary Separation in Constant-Flow Oil Separator
The oily solution first enters the constant-flow oil separator, which features a specially designed internal structure with coated coalescent materials. These materials exhibit oleophilic-hydrophobic properties and strong adsorption capacity for oil and organic impurities. Through the effects of baffle flow and coalescence, suspended oil and dispersed oil are enriched to form an oil film that floats upward, achieving preliminary high-efficiency separation.
Deep Purification in Resin Adsorption Tower
The pretreated solution is then pumped into the resin adsorption tower by a liquid-phase transfer pump. The tower is loaded with our independently developed special oil-removing resin, which has a macroporous structure and cross-linked network. With excellent specific surface area and pore structure, the resin efficiently utilizes its structural advantages to adsorb residual suspended and dissolved oil in the solution through van der Waals forces, further purifying the solution and removing organic matter. When the resin in the adsorption tower reaches saturation, it is switched to a standby tower, and the resin regeneration system is activated to desorb and regenerate the saturated resin, ensuring continuous operation without interruption.
Final Filtration
The purified solution finally flows through a filter equipped with high-performance composite material filter elements, achieving a filtration accuracy of up to 0.2 µm. This ensures interception and removal of any escaping fine particles, guaranteeing the excellent quality and purity of the final oil-removed product.
