Thus, the water circuit is carried out on the elements of the installation.

Flue gases are supplied from the exhaust of the smoke exhauster 25 through a pipeline for transporting flue gases 40 to a product purge system with heated flue gases 13 of a heated third screw loader 12.

The oil-containing product is loaded into the receiving heated tank 1. If necessary, the oil-containing product is pre-sieved through a vibrating screen 42. Water is washed from the product washing system with heated water 2, separating part of the oil products. By heating the receiving heated tank 1, they heat, soften and reduce the viscosity of the oil in the oil-containing product, and washing with heated water significantly increases the yield of the oil. The resulting contaminated water with an oil product through a system for collecting contaminated water with an oil product 3 through a pipeline for transporting contaminated water with an oil product 37 is sent to a tank for receiving and settling contaminated water with an oil product 4, where solid particles are deposited and water is separated from the oil product. Due to the heating of the receiving tank and sedimentation of contaminated water with oil 4, the process of separation of water and oil is accelerated.

From the reservoir of reception and sediment of contaminated water with oil 4, the upper layer of liquid through the overflow pipe 39 is poured into the heated reservoir of water and oil 5 5. In the lower part of the heated reservoir of water and oil 5 is placed a VMA unit, which is a vibratory activator. Under the influence of the VMA installation, almost complete separation of water, solids and oil products occurs. From the upper part of the heated tank of water and oil product sludge 5 through the pipeline for transporting oil 38, the separated oil products are sent to the storage tank of refined oil products 7. From the lower part of the heated tank of water and oil product sludge 5 through the pipeline for transporting heated water 34, the water is sent to the water tank 31.

A partially washed oil-containing product is taken from the receiving heated container 1 by the first heated screw loader 8 and sent to the input of the second heated screw loader 9. At the outlet of the second screw loader 9, the oil-containing product is washed with heated water 10 and the oil-containing product is washed. The resulting contaminated water with oil passes through the second screw loader 9. Due to the counterflow of water and the supplied oil-containing product inside the second screw loader 9, high-quality mixing and separation of solids and contaminated water with the oil occurs. Through the inlet of the second screw loader 9, the contaminated water with the oil product enters the collection system of the polluted water pouring out of the heated second screw loader 9 with the oil 11 and then through the pipeline for transporting the polluted water with the oil 37 enters the tank for receiving and settling contaminated water with the oil 4 which is mixed with contaminated water with oil from the receiving heated tank 1.

The product (mechanical impurities) separated from the contaminated water with the oil product and the oil product residues are supplied with a heated second screw loader 9 to the inlet of the heated third screw loader 12. The product is purged from the outlet of the third screw loader 12 using a heated air purge system 13. The product is dried. The product is fed through the outlet of the heated third screw loader 12 to the receiving unit 14, connected to the drum furnace 15 and then to the drum furnace 15. Depending on the content of the oil component in the product and the required firing duration, the angle of the drum furnace 15 is adjusted on an adjustable frame 18. Drum the furnace 15 is rotated in the roller bearings 17. The hot gases of the burner 19, penetrating and passing through the product repeatedly spilled in the rotary inclined drum furnace, heat it and evaporate the oil Products, oil product vapors ignite and burn, generating additional heat and raising the temperature in the drum furnace 15, and non-combustible inert components in the form of sand, ash or grant are poured through the lower end of the drum furnace 15 into the receiving tank 41 to collect the purified product.

Rags, gloves, clothes, etc., which are in use and have become unusable, are thrown into the drum kiln through a window for receiving and disposing of used materials 16. combustible materials.

Flue gases from the drum furnace 15 are sucked in by a smoke exhauster 25 and pass through an oil heat exchanger 21, heat the oil, which then carries heat to the elements of the installation. The expansion tank 22 prevents the destruction of the oil heat exchanger 21 when the oil is heated.

Next, the flue gas enters the flue gas cleaning unit 23, where large coarse particles are separated in the chipper 24, and then the flue gas is sent to the cyclone 26, where further solid particles are separated, to the flue gas irrigation unit 27, where due to wetting with water, the final cleaning of flue gases from solid particles occurs. After cleaning, the flue gas enters the economizer 28 and heats the air in the air tank 29 and the heat exchanger 30 and heats the water in the water tank 31. After that, the flue gas is released into the atmosphere through the flue gas exhaust pipe 32.

Due to the oil heating of the elements of the proposed installation, it is possible to carry out a cleaning and disposal process at elevated temperature, i.e. under conditions of reducing the viscosity of the oil component of the oil-containing product, and, therefore, to achieve a more complete separation of the oil component from the solid part of the product, which determines the increased degree of yield of oil components. Due to the multi-stage and diverse purification of flue gases from particulate matter, it is possible to reduce emissions of particulate matter into the atmosphere.

The application of the proposed installation will solve the problem of increasing the degree of release of oil components and reducing emissions of particulate matter into the atmosphere.
