SU1564119A1 - Device for separation of oil and water - Google Patents

Abstract

The invention relates to the separation of immiscible liquids under the force of gravity in septic tanks equipped with partitions, and makes it possible to increase the efficiency of the separation of oil and water due to the labyrinthic flow of fluid in the device. A device for separating oil and water contains a tank, vertical separation walls installed therein, pipes for introducing the mixture and withdrawing clarified water, L-shaped bypass pipes, S-pipes for oil withdrawing and collectors. Partitions form a series of connected chambers. In alternate order, opposite side walls of the chambers are equipped with overflow pipes and branch pipes for draining oil. The upper part of the oil outlet pipes is adapted for vertical movement. 1 hp ff, 5 ill.

Description

The invention relates to the separation of immiscible liquids, preferably under the influence of gravity in septic tanks equipped with partitions.

The purpose of the invention is to increase the efficiency of separation of oil and water by increasing the surface of the separation media.

Figure 1 shows the device, a longitudinal section; in FIG. 2, the same, in plan view; in FIG. 3, section A-A-Ia of Figure 2; FIG. 4 shows the node I in FIG. 3, FIG. 5 shows a section BB in FIG. 4.

A device for separating oil and water contains a container 1 with a nozzle 2 for introducing the mixture, vertical partitions 3 are installed inside the vessel 1, which divide it into a number of chambers, the edges of the partitions are located above the liquid level. In the partitions, in alternate order, along the side walls of the container, L-shaped overflow pipes 4 are fixed, the knee 5 of which is immersed in the liquid, and the knee 6 enters the adjacent chamber above the liquid level. A nozzle for injecting a mixture of the by-pass nozzle is located on opposite walls of the chamber diagonally relative to each other. The nozzle 7 serves to output the clarified zod.

In the side walls of the tank are fixed S-shaped nozzles 8 for the oil outlet, the upper parts of which are located at the liquid level and are made

Invention Formula ten 1, A device for separating oil and water, containing a container, vertical dividing walls installed therein, forming successively connected chambers, each of which has an overflow pipe and an oil outlet pipe, inlet-mix pipe connections and clear water outlet, characterized in that In order to increase the efficiency of the separation of oil and water, it is equipped with oil drain collectors located outside the side walls of the tank, the bypass nozzles are made of L-shaped inlets At a distance from the bottom of the chamber, a-days off, in the next chamber above the liquid level, the oil outlets are S-shaped, the inlets of which are located at the level of the liquid and the outlets are connected to the collectors, while S-shaped and D -shaped pipes are installed alternately at the opposite to soflti works as follows. Water-oil enters the mixture through pipe 2 into the first chamber, where the separation of oil from thieves begins. Oil accumulating on the surface is discharged through the pipes 8 to the collectors 13, and the mixture flows through the pipe 4 to the next chamber. The arrangement of the pipes 4 in alternating order at the side walls of the chambers provides a labyrinth current of bone, which increases the time during which it separates in each chamber. The clarified water is discharged through the nozzle 7 "Depending on the set flow rate at a given degree of cleaning, the screw 11 connected to the washer 10 adjusts the position of the upper part of the nozzle 8 in bytes of oil relative to the liquid level. The proposed device allows to increase the degree of water purification from oil. five 0 about 1, A device for separating oil and water, containing a container, vertical dividing walls installed therein, forming successively connected chambers, each of which has an overflow pipe and an oil outlet pipe, inlet-mix pipe connections and clear water outlet, characterized in that In order to increase the efficiency of the separation of oil and water, it is equipped with oil drain collectors located outside the side walls of the tank, the bypass nozzles are made of L-shaped inlets At a distance from the bottom of the chamber, a-days off, in the next chamber above the liquid level, the oil outlets are S-shaped, the inlets of which are located at the level of the liquid and the outlets are connected to the collectors, while S-shaped and D -shaped pipes are installed alternately at the opposite Mzhhovy walls of chambers. 2.
