Abstract

The invention relates to devices for purifying water from oil, can be used in oil production, petrochemical, engineering, energy, metallurgy, writing industry, transport enterprises and allows for increasing the degree of water purification. The device contains a cylindrical housing (k) 1 with a coaxially located cylinder (C) 2 connected to a cone 3 in the lower part, a nozzle 4 is tangentially connected to the cone to supply purified water. The inlet of the nozzle 5 for drainage is located in the lower part of K1 under the C2. The perforated pipeline 6 for supplying air is located around C2 at the level of its lower base. The device has a chute 7 for receiving supernatant oils and a nozzle 8 with a valve for periodically draining the oils from the device. 1 il. with f

The invention relates to devices for the treatment of water containing liquid water-insoluble substances, such as petroleum products, oils, fats (under the general concept of oil), and can be used in oil-producing, petrochemical, engineering, energy, metallurgical, food industry, transport enterprises x

The purpose of the invention is to increase the degree of water purification.

The drawing shows a device for purifying water from oils.

The device contains a cylindrical housing 1 which is coaxially inside a cylindrical chamber 2, in the lower part connected to a reverse truncated cone 3.Pet4, for supplying source water tangentially installed in the lower part of the cone 3 (Inlet port 5 for draining purified water located in the lower part of the housing 1. The perforated pipeline 6 for supplying air is located in the space between the housing 1 and the cylindrical chamber 2 at the level of the upper base of the cone 3. The device has a groove 7 for Receiving surfaced oils and nozzle 8. with a latch for periodic removal of oil from the trough 7.

The device works as follows.

The waste water enters the chamber 2 through the pipe 4, which is tangentially attached to the cone 3. The tangential connection of the pipe 4 to the generator of the cone 3 imparts a circular motion to the water flow in the cylinder. As a result of circular motion, centrifugal forces are generated that act on water and oil particles. In the centrifugal field, the oil particles, the density of water, are forced out into the central part of the flow and, together with the movements, the flow of clarified water due to the lower density of oils, as compared to the density of water, rises. Water, reaching the upper edge of chamber 2, bends around it and moves down the gap between the outer wall of chamber 2 and the walls of housing 1. In the path of water movement from chamber 2 and in the gap area along

a stream of water meets on its way upward air bubbles emerging from a perforated conduit 6 installed around chamber 2. When meeting with air bubbles, the oil particles are fixed on the surface of the bubbles and the aggregates, the air bubble - the oil particles rise upwards.

After the oil has been separated, the water enters the nozzle 5 to release it from the chamber. The central location of the inlet of the nozzle 5 under the chamber 2 contributes to a uniform overflow of water through the edges of the chamber 2, and accordingly, a uniform flow of water in the gap between the housing and the chamber.

The oils that float to the surface of the water are collected in the upper conical zone of the device, are poured into the chute 7 and periodically, as they accumulate, are withdrawn from the cleaning device.

These features in the proposed device can significantly (5-6 times) increase the degree of water purification from oils in comparison with the known, thereby reducing the consumption of materials.
