Description
Technical Field
The utility model belongs to the technical field of copper cobalt hydrometallurgy preparation cathode copper, concretely relates to ultrasonic demulsification coalescence air supporting deoiling composite set.
Background
Copper is used as an important nonferrous metal in various fields of national economy. Although the world's copper productivity continues to increase, the supply-demand contradiction still exists. Particularly, along with the gradual reduction of the grade of copper ores in recent years, more and more lean, fine, impurity and difficult ores and general attention to the environmental protection problem are paid to copper hydrometallurgy.
Since 1970, the copper solvent extraction technology has been rapidly developed, the types of extractants are continuously updated, and the extraction performance is continuously improved. The extraction operation is continuously optimized, and the scale of the global copper oxide ore leaching-extraction-electrodeposition factory is gradually enlarged. By 2016, the worldwide wet copper yield has accounted for 25% of the total copper yield. The method for producing the electrodeposited copper from the copper material by adopting the leaching-extracting-electrodeposition process is an economic and effective method.
However, in the copper back extraction process, the organic phase and the copper-rich aqueous phase are inevitably carried in a certain degree, the organic carrying amount is different according to different process conditions and operation control levels, generally, the organic carrying amount is dozens of ppm to hundreds of ppm, and the carried organic extracting agent can cause the phenomena of serious influence on the quality of the electrodeposited copper, such as plate burning of an electrodeposited cathode plate, blackening and brittleness of a copper plate, incompact crystallization and the like. Therefore, in order to meet the requirements of the subsequent copper electrodeposition process, the back extraction copper-rich aqueous phase needs to be subjected to oil removal treatment.
The existing oil removing method can be mainly divided into four categories according to the oil removing principle: chemical methods (chemical oxidation, salting out, coagulation, etc.); physical methods (centrifugation, gravity separation, filtration, coarse granulation, membrane separation, etc.); biochemical methods (biological filters, activated sludge, etc.); physicochemical methods (electrolysis, adsorption, flotation, etc.).
Ultrasonic wave is a high-frequency mechanical wave and has the characteristics of concentrated energy, strong penetrating power and the like. Ultrasonic waves are a sine wave that can produce cavitation effects in solution. When ultrasonic waves pass through oily wastewater, micro oil drops and water vibrate together, and particles with different particle sizes collide with each other, are broken, are bonded with each other, grow and the like due to different relative vibration speeds, so that the purposes of demulsification and oil removal are achieved.
The coalescence type oil removing mainly utilizes oleophylic hydrophobic coalescence filler which is subjected to modification treatment, fully utilizes the coalescence performance of the coalescence filler, can ensure that whether fine extractant oil drops are gradually coalesced into larger oil particles on the surface of the oil drops, can separate from the surface of a coarse grained material to float when the particle size is large enough, and finally can achieve the purpose of collecting and recovering in an oil collecting tank at the top of oil removing.
The air floatation oil removal technology can be divided into the following steps according to the mode of generating bubbles: the air-float method includes air-float method, electrolytic air-float method, dissolved air-float method and biochemical air-float method.
The requirement on oil removal is usually very high in copper wet production, various existing oil removal technologies have respective advantages and disadvantages, the existing oil removal technology cannot achieve ideal oil removal effect easily, for example, the oil content before oil removal is 100mg/L, the oil content after oil removal can only be reduced to about 5mg/L generally, and especially in large-scale hydrometallurgy plants, so that the oil removal technology needs to be further optimized, the oil removal effect is improved, and the key technical problem that the oil content of liquid before electrodeposition in large and medium-scale copper-cobalt hydrometallurgy plants exceeds the standard is solved.
