Oil product catcher - a pipe with a receiving funnel is placed in the first compartment above the top of the outlet pipe. 1 il.

Description

The invention relates to devices for the treatment of wastewater from steam, gas, petroleum products, in particular fuel oil.

The purpose of the invention is to increase the degree of purification of vapor-gas-oil-containing water from oil impurities.

The drawing shows a setup for water treatment.

The device includes a container 1 with a bottom 2 and a cover 3, vertical partitions 4 and 5, fixed successively in the bottom 2 and the cover 3 of the container and dividing the capacity into compartments. Partitions 4 and 5 have shelves 6 fixed at their free ends. In the first downstream compartment of the tank 1, an open cyclone 7 is installed above the water level with a damper 8 at the bottom. The damper 8 has the shape of a spherical ring with a U-shaped tube 9. In the upper part of the first compartment is installed a means for collecting oil impurities, made in the form of

vertical pipe 10 with a receiving funnel.

The purified water discharge pipeline is equipped with a siphon 11 with a drainage pipe 12, inlet I of which is located in the lower part of the last compartment, and the upper section is located above the lower cyclone outlet, a filter 13 located outside the tank at the downstream part of the siphon and a hydraulic lock 14 with a drainage pipe 15. The device also contains a nozzle 16 for supplying the water to be purified, taps 17 for dropping and monitoring the presence of petroleum products, fittings 18 for connecting the container to the atmosphere and drainage fittings 19 at the bottom of the container.

The device works as follows.

Before the installation of the tank 1 begins to work, it is filled with clean water until the appearance of water after the filter in order to avoid the movement of fuel oil with purified water during oOs 00

m start. The vapor-gas-oil pipeline to the mixture enters through pipe 16 into a hydrocyclone 7, where steam (gas) is separated from the liquid and is removed from the upper part of the cyclone, and the liquid is directed downwards, enters tank 1, where it is separated. The conical part of the cyclone is immersed in a liquid. To ensure the laminar flow of the liquid from the cyclone, a damper 8 serves in the mass in the tank. Oil products are diverted through a U-shaped branch pipe. Subsequently, at a certain speed of fluid movement, a more thorough separation of the mixture occurs when the flow direction is changed by partitions 4 and 5 with shelves (5. When the liquid reaches the level of the discharge pipeline, the purified water from the lower part of the tank enters the filter 13, where water is purified from oil products Water is then discharged through a hydraulic lock 14 with a drainage pipe 15 and used for its intended purpose. The drain pipe 12 with a siphon 11 is used to overflow the purified water from the last compartment of the tank 1 and remove kuum (siphon) when stopping or maintaining the supply of contaminated water to tank 1 to prevent the oil-containing layer from seizing when water is removed.The oil-containing layer is removed to the tank for subsequent combustion through pipe 10 that is placed inside the first compartment Season of the year. In the event of the presence of significant quantities of petroleum products in the subsequent compartments, they are discharged through the curvature 17, into the receivers for combustion. All compartments communicate with the atmosphere through fittings 18. After the installation is terminated, the tank is cleaned / washed through drainage fittings 19.

The location of the filter, the flow of water into it through the discharge pipeline almost completely eliminates the entry of oil impurities with the purified water from the installation, improves the quality of cleaning, and makes it easier to maintain the filter and the filler. In addition, it provides ease of filter maintenance and filler replacement,
