Abstract

This invention relates to petroleum irradiation. in particular, ow-. The wastewaters generated during the repair of wells, and is the succession of the known device on the basis of aat. c &n; 1503849. The aim of the invention is to improve the efficiency of the separation of petroleum products from wastewater w reducing the water cut of the separated oil, while providing for bringing the oil content of the waste water to an acceptable value allowing the wastewater to be used without further purification for pumping in reservoir. The device for separating the suspension contains a body with a lerforated partition, a nozzle of inclined plates, a separating compartment in which an inclined lid and stepped upper edges of the inclined plates create conditions for the accumulation of oil contact mass, which serves to concentrate oil droplets of different dispersity. 1 ill. The invention relates to the oil industry, in particular, to a device for separating the suspension formed during the repair of wells, and is an extension of the known device according to ed. St. N! 1503849.- The purpose of the invention is to increase the effi- ciency of the separation of petroleum products and to reduce the water cut.

Description

plates 7, vrplivayuschie drops of oil SMECh14VEYUT from the inside of the inclined surface of the cover 12, Under the surface of the cover 12 accumulates a layer of oil this layer serves as a contact mass for drops of oil entering the separation chamber K-H with suspension. In the contact layer of the act, the process of merging of oil droplets is completed. Thus, the layer of contact mass provides the concentration of the emerging droplets and film. As the layer of contact mass accumulates, the JB nozzle 15 is displaced: When pouring over the erhne 13 edges of the plates 7, the suspension and its solid phase are distributed in inclined compartments 8, in which the downward flow in the form of mrnosuspension moves to the filtration zone 10, where De is filtered through the accumulated solid phase. As the filtration zone 10 is overthrown. Suspension from the largest particles of solid phaseM enters. and in each subsequent compartment 8 of the inclined plates 7 a suspension of the penzi enters with smaller and smaller planks of the solid phase; then during continuous movement of the solid phase along the expanding zone 10 to the ecucka 11 mercury for | There is a lot of state layer filter layer. For example, the hydrostatic pressure of the liquid on the filtering layer from the lower parts of the compartments 8 promotes the transfer of accumulated solid phase from the compartments to the layer of zone 10, while the clarified suspension ;; flows through the perforated partition 4 into the drainage chamber 5 and is removed from the device through connection 6. the phase, as it moves from the top to the bottom, is removed from the device through the pipe 11. The pipe 15 ensures that the oil product is withdrawn as it accumulates a layer of contact mass under the inclined lid 12.

Thanks to the separation compartment 14, it is possible to separate and concentrate droplets of oil of different dispersity, which

increases the efficiency of separation of oil from waste water. In addition, the staggered arrangement of the upper edges 13 7 prevents the jet from entering

waste water directly into the pipe; 15 removal of petroleum products.

So, for example, for cleaning wastewater generated during flushing a well at a volume flow rate of 40 l / s, the difference between the heights of the edges of the plates is assumed to be 16 mm with the width of the plates in the upper part 0.6 m.

..:

where D h - the height of the overflow of liquid through a single plane;

About - volumetric flow of waste water.

B- width of the upper edge of the inclined plate, m.

The value obtained is multiplied by the number of inclined plates, including the number and inclination of the device.

The use of the proposed device, in which not only separation, HO and concentration of dispersed oil, allows further purification of waste water from oil droplets of different dispersiveness. After this cleaning of the waste water is pumped back into the reservoir, oil with a minimum amount of residual water is pumped into the collection line .
