The invention relates to the purification of organic liquids with a viscosity of; the range is 0.6–50 cSt and can be used in petrochemical, petrochemical and chemical industries, in production associated with the use of petroleum products that do not contain emulsified water in amounts exceeding its solubility in fluid.

The purpose of the invention is to simplify the design of the coagulating filter and AND (using it to clean liquids | with a viscosity of up to 50 cSt,

I, the drawing shows schematically the proposed filter separator, section.

A device for cleaning liquids from emulsified water is a housing 1 with inlet 2 and outlet 3 nozzles, inside the housing on a common distribution manifold 4. . Metal, perforated 5 cups 5 in the lower part are placed with two layers of coagulating material 6 and 7 on the cups. The glasses are perforated with holes or longitudinal slots along the bottom bulk layer (about 8 and covered with (the same height) a metal mesh 9 with a diameter of 1.4-2.0 mm Tseek, the bottom of the glass 10 is plugged. The glasses are attached to the number of people using flange connections or threaded bushings at about the same level. The number of glasses is determined by the possibility of mounting them ; maximal density. Diameter C1 Akanov It is in the range of 80-1 So mm and is determined by the viscosity of the fluid being cleaned and its speed if yes and. The perforation area ensures the uniform operation of the surface of the entire grid. Under the glasses there is a stop zone 11, at the bottom of which is a water-repellent stage 12), for example, from a grid treated with torplast emulsion Restrictions on heights for bulk layers (not less than 350 mm for the upper layer and 450 mm l lower) are determined by the fact that below these heights of the layers the cleaning quality in the speed range in Above 25 m / h deteriorates, i.e. the water content remains above the limit of its solubility in the liquid. The purpose of the upper layer (with a particle diameter of 0.730

1.2 mm) - provide nominal coagulation. The size of the formed droplets is determined by the scale of the porosity of the layer, but if the particle size is larger than the critical one, the coagulation quality is discretely degraded. If this forming layer is composed of particles with a size of less than 0.7 mm, this leads to a sharp increase in hydraulic resistance (P ci

--j | 5) and a decrease in the scale of the formed droplets, which makes it difficult for them to coalesce in the bottom layer. The size of the granules of the lower layer (1.7-2.5 mm) is determined by the need for further coalescence (enlargement) of the droplets formed in the first layer. When using granules with a size below the specified limit, the enlargement of the drops is insignificant, and exceeding the specified limit leads to a breakthrough in the range of even moderate speeds. The grid cell size (1.4-2.0 mm) is determined by the conditions for holding the load and excluding the reverse crushing of the droplets.

The device works as follows.

Cleaning fluid containing

emulsified water through the pipe 2 and the distribution manifold 4 enters the upper coagulating layer, passes the lower coagulating layer and exit through the side perforation of the glasses and the grid into the settling zone. In the settling zone, the enlarged liquid droplets settle to the lower part of the hull and are periodically drained, and the purified liquid is withdrawn through the water-repellent stage 12.
