SU1433473A1 - Method of separating emulsions - Google Patents

Abstract

The invention can be used to separate emulsions formed in the food industry, in transport, in the power industry. The purpose of the invention is to increase the efficiency of the process of separation of emulsions in the channels (K). The channels are formed by fixed walls and moving surfaces, such as disks, on which recoverable particles of the dispersed phase coalesce, forming a film, which is then removed by the sliding wings of the grooves. A cleaned dispersion medium is fed into the initial section K through special distributors tightly adjacent to movable coalescing disks, the processed emulsion is introduced, which is pressed by the flow of purified medium to moving coalescing disks to form a thin layer where the separation process takes place. 1 il.

The invention relates to the physical: fats and can be used in chemical, petrochemical, gas, food industries, construction engineering, transport and energy, for example, for the separation of oil-in-water emulsions.

The purpose of the invention is to increase the efficiency of the emulsion separation process.

The drawing shows the implementation of the proposed method. The emulsions are processed in channels formed by fixed walls and mobile disks, made of a material wetted by a dispersed phase substance. The dispersion medium (water) purified from impurities is recycled to the initial section of the sanals with a flow rate ensuring the laminar flow of its flow. Through the distributor, adjacent to the movable disks, iodine the processed emulsion, which is pressed by a stream of clean dispersed medium to the movable disks, is a thin wall layer in which the particle of the dispersed phase contains. - bursts the particles of the dispersed phase to the movable disks, where they coalesce. However, since the distance of any particles from the disk in the proposed method is much smaller, hro and the processing time of the emulsion is reduced.

Since movable discs are made of a material, it is better to disperse a wetted substance than a substance. the dispersion medium, the particle phase spreads on the surface of the disks, forming a layer of the substance of the dispersed phase, is transported further above the surface of the emulsion until

until the tightly fitting wings of the grooves sliding along the surface of the movable disk remove the layer formed from the surface of the disks onto inclined grooves along which the extracted product is drained by gravity into a special collection. The purified dispersion medium is withdrawn from the system, and a part of it is recycled to the initial part of the channels.

PRI im p Salt emulsion (RF 860 kg / m) with particle size g (4-5). 10% in water (kg / m) is treated in channels made with distances between fixed walls and movable discs (polypropylene, 5, and pieces) equal to 10 m. In the first case (without recycling water) at an emulsion consumption of 100 l / h (corresponding to an average speed in the channels of 0.003 m / s), the cleaning efficiency is no more than 30%. In the second case, a part of purified water is fed into recycling to the initial part of the channels with a flow rate of 30 l / h, and the emulsion through distributors adjacent to movable discs with a flow rate of 70 l / h, the efficiency of water purification from oil products is 95%.
