Description

The proposed utility model relates to the field of the oil refining industry and can be used to solve the problem of processing and rendering harmless to various oil-containing wastes generated during oil production and / or processing and disposed of at various landfills, sludge storages, storage tanks, ponds, oil barns, etc.

The well-known "Production line" (Installation, equipment) for the processing and disposal of oily waste ("Technology for the processing and disposal of oil waste" // Technology and equipment for the processing and disposal of oil-containing waste and oil sludge:

Modern Russian technologies. (A series of reference books. Volume 2) Yaroslavl: 2003, p.107-110).

The well-known “Production line” - a waste oil disposal line includes a complex of equipment, including storage facilities (tanks) with solid (oil-contaminated ponds) and liquid sludge, grabs - receiving silos, skip elevator, limestone storage facilities, silos - batchers of initial oil-containing waste and quicklime lime, dispensers of the special preparation "Econaft", mixer with a mixing device, pumps, pipelines, storage hopper for the finished product, lifting equipment (crane - beam), vehicles Islands (dump) to display the finished products from oil waste recycling.

The disposal and processing of oily waste on the well-known "Production line" is as follows.

The initial paste-like oil and oil waste - oil sludge, liquid waste and contaminated with oil, oil ("greased") soils are delivered to the processing and disposal of oil waste by trucks (dump trucks) and unloaded in special receiving containers - waste storage. Quicklime is discharged (reloaded from dump trucks) to other storage facilities (consumable containers).

To ensure the neutralization of oil wastes, first, quicklime is fed from the storage facility (container) using a grab to the metering hopper, then it is loaded with a skip hoist into the mixer receiving hopper and distributed with the screw along the entire length of the mixer. After that, in a similar way, paste-like oil wastes are loaded into the mixer; liquid oily waste is pumped into the mixer with a metering pump. A special preparation Econaft is also loaded into the mixer, which consists of two components: quicklime (up to 95%) and a modifier (up to 5%), which are used as a complete ester of glycerol and higher fatty acids - triglyceride. The purpose of this modifier is to impart hydrophobizing properties to the resulting product.

After mixing the oil sludge with quicklime and a modifier, water is supplied to the mixer. At the same time, under conditions of intensive mixing, the oil products are uniformly adsorbed on the surface of calcium hydroxide particles, and a “dry” powder (“PUN”) is formed, which is the final (marketable) product of the processing and disposal of oil waste. At the end of the process, the PUN powder is discharged through the mixer discharge window to the conveyor and fed to the storage hopper, from where the marketable product, PUN powder, is transferred to dump trucks and sent to consumers who use this powder as one of the components for production

asphalt mixtures, for the repair of roads, for the manufacture of building materials and products from them.

A disadvantage of the known production line is that it does not include equipment for the extraction and disposal of oil phase waste, which significantly reduces the economic efficiency of the process of processing oil waste.

Patent holder: Specialized Professional Emergency Response Team of the Ministry of Emergencies of Russia LLC " NATURE ", Inventor: Kurchenko AB .; Syktyvkar title of the invention:" A method of preparing oil sludge for processing and installation for its implementation ").

The well-known installation (production line) includes the following main equipment: the receiving tank of the original sludge with steam registers inside (not shown), a vibrating screen with drain, an intermediate tank for receiving oily liquid, a pump, a container for collecting separated impurities, while the tank equipped with a mesh or mesh box with cells of at least 25 mm and has a cover (not shown in the drawing). The installation also comprises a pump, a sand separator (hydrocyclone) and an oil-containing liquid feed tank.

Oil waste processing at this installation is carried out as follows.

The original liquid oil sludge from emergency oil spills or temporary storage places is served on the grid of the receiving tank. Fragments of mechanical impurities larger than 25 mm are retained on the grid. The tank is filled with the initial slurry to a level of no more than 10 cm from the upper edge, after which the tank is closed with lids. Oil sludge is heated for several hours using steam registers with saturated steam to a temperature of at least 70 ° C. to control

sludge heating temperature uses a thermometer with a stem holder. The oil sludge heated to a pumped state is pumped to a vibrating screen with a mesh size of 0.16 mm. Sludge supply is regulated by a valve on the pressure pipe of the pump. On a vibrating screen, separation of mechanical impurities larger than 0.15 mm occurs, which, as a result of linear vibrations, is discharged into the container. After separation of large fractions, an oily liquid from the first intermediate tank is pumped to a sand separator (hydrocyclone), where mechanical impurities of more than 0.05 mm are separated. The purified liquid enters the second intermediate tank, from where it is pumped into the raw material tank of known plants or directly to the decanter. Particles of mechanical impurities separated by centrifugal forces from the sand separator are discharged into a container.

The disadvantage of this installation is that it does not contain the necessary equipment for the selective extraction of oil and / or oil products and their return to production, in addition, the known installation does not provide for the possibility of disposal (for example in the form of commercial products) of a solid phase separated from oil waste.
