(54) DEVICE FOR CLEANING WASTE WATER ..

FROM EMULSATED ORGANIC LIQUIDS

one

The invention relates to devices for purifying water from emulsions of organic liquids and may find application in the chemical, petrochemical, and other industries.

The closest to the technical essence and the achieved effect to the proposed invention is a device for purifying water from an emulsion of an organic liquid, comprising a housing with fittings for wastewater inlet and outlet for the organic and aqueous phases. particles and separating organic liquid droplets from water. I.

The drawback of the device is low productivity due to the inefficient use of the perforated conical surface for the separation of liquids with different specific densities, since after passing through the perforated partition, a drop of light liquid is immediately affected by the flow of the purified liquid. As the flow rate increases, some droplets are captured by the purified flow before they enter the lifting zone enclosed by channels.

The purpose of the invention is to improve the performance of the device while maintaining the cleaning efficiency.

This goal is achieved by the fact that the device, including a housing with fittings and a perforated partition, is provided with an additional conical partition with nozzles,

20 placed in a checkerboard pattern and directed to the axis of the cone, with an additional partition placed inside the main one. 3 Ha of FIG. I shows the device, vertical section; FIG. 2 shows an assembly G in FIG. 1, The water treatment device consists of a housing 1CO by fittings 2 wastewater inlets, 3 organic outputs and 4 water phases, a perforated cone 5, a coalescing layer 6 and a housing 7 with overflow pipes 8 The upper part of the cone 5 does not have perforations, since it is an organic phase collector connected by a pipe with fitting 3. The device operates as follows. The water to be cleaned enters the apparatus through a tangentially located fitting 2, passes through a coalescing layer 6, where the aggregation of organic liquid droplets takes place. Drops of organic liquid through the cone apertures, the size of which is smaller than the diameter of the particles of the coalescing layer, enter the space of the cones. At this point, the organic liquid drops are separated from the water flow, as with a sufficient area of the living cross section of the perforation of the cones, the flow rate of the liquid will be less than the free lift speed of the droplet. As the flow rate increases, some drops of organic liquid can be captured by the flow and enter the inlet of the lower cone, the diameter of which exceeds the diameter of the openings of the upper cone. In the nozzle, the droplets move along trajectories directed toward its upper noBepxHoctH, and reach it at a certain distance from the inlet. Since the velocity of the fluid at the top of the nozzle is close to zero, the droplets are concentrated at the upper surface of the nozzle. Enlarged droplets of organic liquid enter the flow of the purified solution. Thus, division of the flow into phases and speeds occurs. The presence of nozzles on the lower cone facilitates the collection of organic drops in the upper part of the body, since the droplets exit from the nozzle to the infusion zone. In order to better separate the organic and aqueous phases, the free ends of the nozzles are cut at a certain angle. The placement of the pipes in staggered order over the surface of the cone reduces the likelihood of droplets coming out of the lower nozzles, under the streams of purified water moving in them from the upper nozzles. Rising, the droplets are collected in the upper part of the cone in a continuous phase, which is passed through a pipeline connected to fitting 3 of the organic phase. The performance of the proposed device will allow increasing the productivity without reducing the quality of cleaning of the processed solutions.
