Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of emulsion treatment, and more specifically to a device for treating highly concentrated oil-in-water emulsion. Background Art
[0002] The main component of the emulsion is machine oil, which comes from the mechanical processing and metal surface treatment industries. It contains soap surfactants such as petroleum, sodium sulfonate, and oleic acid soap, which have the ability to reduce the surface tension of liquids. The non-polar ends are adsorbed in the oil particles, and the polar ends extend into the water. The polar ends are ionized, resulting in a double-layer phenomenon in which the oil interface is coated with a layer of negative charge, thus forming a barrier to prevent the aggregation of oil particles. In addition, the hydrophilic solid particles in the emulsion can also keep the emulsified oil stably dispersed in the water. Part of the area of the solid particles is wetted by the oil, and most of the area is wetted by the water, hindering the aggregation of oil particles. The oil film on the surface of the emulsified oil hinders the dissolution of oxygen in the water, causing hypoxia in the water, the death of organisms, and a foul smell, seriously polluting the environment.
[0003] The current treatment methods mainly include electrolysis, electrostatic filtration, ultrafiltration, gravity separation, skimming, etc. The current treatment methods have the characteristics of large investment, large floor area, and high operating costs.
[0004] Therefore, the utility model proposes a device for treating highly concentrated oil-in-water emulsion to solve the above problems. Summary of the Utility Model

[0012] The technical effects and advantages of the present utility model:
[0013] 1. In the present utility model, the emulsion to be treated is injected into the oil separation tank through the injection pipe. When the emulsion is injected into the oil separation tank, it will be blocked by the first partition, avoiding the direct injection of the emulsion in the oil separation tank and causing the emulsion in the oil separation tank to be in an overall flowing state.

And the liquid is secondarily isolated by the second partition plate 105, ensuring that the liquid in the separation oil tank 101 can quickly stand still, facilitating the precipitation of the emulsion, so that when the L-shaped pipeline 106 extracts the emulsion in the separation oil tank 101, the floating oil in the emulsion can be isolated, and then it is transported to the centrifugal filtration device 206 to remove the fixed particulate matter in the waste liquid. The centrifugal mesh number is ensured to be within eighty meshes. After centrifugation, the emulsion directly flows into the concentration water tank 201, and then through the operation of the first water pump 202, the emulsion in the concentration water tank 201 is transported into the first pipeline 203 and then transported to the ultrafiltration membrane filtration module 301. Then the emulsion passes through the tubular membrane and operates in a large-flow cross-flow manner. The membrane intercepts the macromolecular emulsified oil through the micron pore diameter, and the clear water flows to the clear water tank body 401 through the third pipeline 304 and the fourth pipeline 305. Then the concentrated emulsion is transported to the concentration water tank 201 again through the fifth pipeline 306. After several reciprocating concentrations, the concentration of the emulsion can be completed. The clear water in the clear water tank body 401 can be directly discharged through the first discharge pipeline 402 and the second discharge pipeline 404 by opening the solenoid valve 403 after the processing is completed. The concentrated emulsion is discharged from the equipment through the operation of the second water pump 204 and then through the second pipeline 205, achieving the purpose of physical concentration without adding demulsifying agents, reducing the operation cost, and at the same time achieving a high concentration multiple, reducing the cost of outsourcing the disposal of waste oil, a single emulsion oil waste liquid, and realizing the effect of recycling and resource reuse.
