The purpose of the invention is to improve the quality of separation and device performance.

FIG. 1 shows the device, a general view; in fig. 2 - connection of the distributor with a branch pipe.

The device consists of a housing 1 divided by partitions 2-5 into an entrance 6, separating 7 and an outlet 8 chambers, each of which is equipped with a bunker 9 for collecting sludge with a branch pipe 10 and a locking element 11.

A drip gutter 12 and a nozzle 13 for gas outlet are installed on the body, and a pipe 14 for product input is installed on the side of the inlet chamber. the lower part of the entrance chamber b along its entire width, the passage between partitions 2 and 3, enters the separating chamber 7 above the lower thin layer module 17. Heavy mechanical impurities settle into the bunker 9 of the entrance chamber 6.

Device by π. 1, characterized in that the tangential nozzle of the product input is connected to the lower part of the distributor, and the longitudinal slots on it are offset by an angle of 270-360 ° from the nozzle axis in the direction of movement of the original product. Zi, „, 1247037 Fig4 2 one 1247037 The device relates to the separation of liquids, namely the production of oil wells on the components, and can be used in the oil, gas and chemical industries. The purpose of the invention is to improve the quality of separation and device performance. FIG. 1 shows the device, a general view; in fig. 2 - connection of the distributor with the pipe. The device consists of a housing 1, divided by partitions 2-5 on the inlet 6, separating 7 and the outlet 8 of the chamber, each of which is equipped with a bunker 9 for collecting sediment with the pipe 10 and the locking element 11. A drip gutter 12 and a nozzle 13 for gas withdrawal are installed on the body, and a product insertion tube 14 is installed on the side of the inlet chamber, which is tangentially connected to the middle of the lower part of the distributor 15 located horizontally in the upper part of the inlet chamber over its entire width. In the upper and lower parts of the separating chamber along its entire length and width there are removable countercurrent steeply inclined thin-layer modules 16 and 17. An oil collector 18, collection 19 emulsion, collection 20 suspended, water collector 21, branch pipes 22-25 for oil recovery are installed at the output end of the output chamber emulsions, suspensions and water with a shut-off element 26–28 and T-shaped pipes 29–31, which are connected to the upper gas part of the body. In the case above the fluid level, a grid 32 is installed. On the divider 15, slots 33 are made along its entire length, displaced by an angle of 270-360 ° from the axis of the nozzle 14 as the fluid moves. The level of phase separation in the device is regulated by means of T-shaped pipelines. The device works as follows. Production of oil wells through the pipe 14 enters the distributor 15 and further, coming out of it through the slots 33 in a pre-separated form, goes down, and, freely spreading through the inlet chamber 6, is divided into gas, oil, emulsion, water and mechanical impurities. This supply of products to the chamber is most favorable for preliminary separation, which leads to an increase in the efficiency of the process. The gas, emerging, is separated from the liquid and, after passing through the grid 32 and the drop separator 12, is discharged through the pipe 13. The grid 32. destroying the foam layer over the oil reduces its thickness, thereby improving the gas outlet. Coarsely refined oil from the upper part of the inlet chamber 6 over its entire width through the partition 2 enters the separating chamber 7 above the upper thin layer module 16. Coarsely purified water from the lower part of the inlet chamber 6 across its entire width, passing between the partitions 2 and 3, enters the separating chamber 7 above the lower thin-layer module 17. Heavy mechanical impurities settle into the bunker 9 of the entrance chamber 6. In the separating chamber 7, the refined oil, passing horizontally to the partition 4, is poured into the output chamber 8, and not the refined oil, passing from top to bottom through the module 16, is cleared of residual gas, water and mechanical impurities and with the emulsion moves under module 16 horizontally to the exit, and between partitions 4 and 5, rising, enters the output chamber 8. The residual gas from module 16 in an enlarged form floats up into the gas zone and, passing the grid 32, the drop separator 12 and nozzle 13, is removed from chamber 7. Water and mechanical impurities from the module 16 in enlarged form to give a water layer chamber 7. In the separating chamber 7, the coarsely cleaned water, passing through the module 17, is cleared of residual gas, oil and mechanical impurities, moves under module 17 horizontally to the exit under the partition 5, and, rising, enters the output chamber 8, and further into the water collector 21. Residual gas and the oil from module 17 enlarges in enlarged form and flows into the oil layer. Oil, merging with the oil layer, is carried away into the outlet chamber 8, and gas, rising up from the oil, enters the gas zone of the chamber. Mechanical impurities from module 17 enlarged form fall into the bunker 9, from where they are discharged through the pipe 10. Clean oil from the oil tank 18 is discharged through the pipe 22. Clean water from the sump 21 is discharged through the pipe 25 and the T-shaped pipe 31. In the separating chamber between modules 16 and 17, the production is divided by density into two layers — an emulsion layer and a suspension layer, and enters the output chamber 8, where this separation is enhanced. The emulsion enters the emulsion sump 18 and through the nozzle 23 and the T-shaped pipe 29 is removed from the device for further preparation (separation). Suspensions flow into the collection of 20 and through the pipe 24 and the T-shaped pipe 30 is removed from the device for further preparation. Separate removal of these layers increases the performance of the device and reduces the cost of chemicals for the next division. 1247037 Compiled by A. Evdokimova Editor N. Slobodianik Tehred I.
