Oil sludge treatment plant

The invention relates to the field of processing oil sludge, and in particular to installations for the purification of liquid oil sludge with a content of solids up to 20-30%.

A known line for the collection, processing of oil sludge and soil neutralization RU P No. 2075447, containing the installation of the collection, separation of oil sludge, which are mounted pumps, suction devices, filters, coarse and fine filters, hydrocyclone, centrifuge and separators.

However, this installation is stationary, it requires significant costs for the construction of the complex.

Oil sludge, which is a mixture consisting of mechanical impurities, water and oil, is formed in the process of production activities of oil producers; they, oil refineries and transporting enterprises. Oil sludge is classified as waste of toxicity class 4. The greatest danger to the surrounding environment is liquid petroleum sludge (with an impurity content of up to 20%), since due to their fluidity they can penetrate through the non-insulated surface of the pits, which leads to oil and soil contamination of soil.

The objective of the present invention is to develop a collapsible installation for the processing of liquid oil sludge and obtain a cleaned (recovered) oil-containing liquid. The proposed installation is easily transported and installed on any site at the places of temporary storage of oil sludge (near excavation pits and landfills), and upon completion of processing operations it can be transported to the place of further operation. In addition, it is cheaper than existing analogues and does not require large operating costs. The recovered oil-containing liquid obtained from the processing of liquid sludge is further divided into water and marketable oil at the complex refinery facilities available at each developed oil field.

This consists in the technical result, which was in a causal relationship with sushi, the natural features of the invention.

The essential features of the invention (Fig. 1): a collapsible installation for processing liquid oil sludge, containing a device for storing and supplying liquid fuel (1), a boiler plant (2), a tank for receiving and heating sludge (3) with steam registers inside (10) and with a pad brought to it, made at an angle for the vehicle to drive in (9), successively mounted vibrating screens (4) with the possibility of separating mechanical impurities of more than 0.15 mm, a hydrocyclone (5) with the possibility of separating impurities of more than 0.05 mm, desilter (6) s the possibility of separating impurities of more than 0.03 mm, each of which is equipped with a container for collecting the separated particles (11,12,13), while the storage tanks of the vibrating sieve, hydrocyclone and sludge separator are connected via a pipeline, a pump unit (8), a container for collecting and accumulating (7) purified oily liquid, a line for supplying liquid fuel to a boiler plant (14), a line for supplying steam to registers (.15), a system

pipelines connected to the pumping unit, platforms with ladders (16) installed at the level of visual observation of cleaning technology.

The installation is quickly mounted near the landfill for temporary storage of oil sludge or pits of the oil complex. To do this, prepare a site for the installation of the unit, sequentially install a tank for receiving and heating oil sludge, a sieve, a hydrocyclone, a sludge separator, a tank for collecting and accumulating oil-containing liquid. The storage tanks of the vibrating screen, hydrocyclone and desilter are connected by pipes of the appropriate diameter. A device for supplying and storing liquid fuel is connected by a line to a boiler plant, which in turn is connected to steam registers located in a tank for heating. The pump unit with the pumps installed in it by a pipe system will be connected to the technological elements. A platform for driving in the vehicle is additionally brought to the tank for receiving and heating oil sludge, which is installed on the tank’s height, platforms with ladders are installed on top of the cleaning unit, the storage tank and the device for feeding and snoring liquid fuel for visual control of the installation. The installation is carried out within a few days.

Installation works as follows:

Oil sludge from a vehicle located on site (9) is discharged into a heating tank (3), which is also a receiving tank. Aggregate state of oil sludge from viscoplastic to liquid is changed by heating by steam registers (10), steam comes from (2) via line (15). The boiler plant (2) runs on liquid fuel (fuel oil, crude oil, etc.), which is fed by gravity from the storage and supply tank (1) via line (14). Using a slurry pump, the heated liquid sludge is fed to a vibrating screen (4), where particles larger than 0.15 mm are separated (the first stage of purification), after which the oil sludge flows by gravity into the hydrocyclops storage tank, from where it is fed to the hydrocyclone by a slurry pump (5), where particles are separated by a size greater than 0.05 mm (second cleaning stage), then the sludge enters the sludge separator storage tank, from where it is fed to a sludge separator by a slurry pump (6), where particles are separated from more than 0.03 mm (third cleaning stage), while solids are automatically discharged into containers (11,12,13). The purified (recovered) oily liquid enters the storage tank (7), from where it is pumped and taken out to complex factory facilities for separation into water and marketable oil or pumped to the oilfield collection system. During the operation of the installation, the operator constantly conducts visual monitoring from the sites (16) of the cleaning process and the observance of technological modes and parameters. Mechanical impurities, which are mineral soil and organic particles, are mechanically unloaded from containers (11,12,13) and transported to landfills for bioremediation.
