Description

The present invention relates to a technology for cleaning materials and can be used in the purification of various materials from petroleum products, as well as in the aftermath of accidents during transportation of petrochemical products, and the processing of waste with combustible components. A device for cleaning 'porous and dispersed materials is known, comprising a chamber with material and a piping system for purging dry water vapor through the material.

A device for cleaning ceramic materials is known, containing chambers where raw products and a coolant with a temperature of 30-35 ° C are supplied and chambers where the driest products and hot coolant are fed. The disadvantages of these devices include the low efficiency of removing organic impurities, the high energy intensity of the process due to the need to burn additional fuel to produce steam.

Closest to the proposed invention is the prototype device for cleaning beaches, which contains a chassis, on the frame of which is mounted an outgoing cutting knife, a shaking mechanism and a rotary hopper; a throwing drum located under the cutting knife, reflective brushes mounted on a frame above the conveyor, the belt of which is mesh and connected with a shaking mechanism.

The disadvantages of this device include:

1. Poor cleaning quality due to the inability to clean the dispersed material from oil adhering to the particles of the material.

2. The need to move and store in certain places the collected contaminated dispersed material.

3. The need for additional processing of the collected contaminated dispersed material.

The aim of the proposed invention is to improve the quality of treatment. This goal is achieved by the fact that, in contrast to the known device containing an intake working body mounted on the chassis and a perforated conveyor mounted behind it, the novelty is that the device is equipped with a hopper and a steam boiler with a fluidized bed furnace, while the upper branch of the conveyor is passed through the hopper , the upper part of which is connected with the steam generator of the steam boiler, and the lower part, for the collection of petroleum products, with the fluidized bed furnace. .

The drawing shows a General view of a device for cleaning dispersed material 5 from petroleum products.

A device for purifying dispersed material, mainly from petroleum products, contains a steam boiler 1 with a fluidized bed furnace 2, a fan 3 for supplying 10 air and a furnace and fluidized bed formation, a pump 4 and a crane 5 for feeding petroleum products from a tank 6 into a fluidized bed, a crane 7 and a container 8 from which water is supplied to the steam generator 9; a crane 10 and a hopper 11, into which 15 steam is supplied from the steam generator; a knife 12 for collecting contaminated particulate material; a conveyor 13 and 14 for feeding the dispersed material 15 into the steam pumping zone; pinch rollers 16 and hydraulics 17 for 20 to ensure that the bell of the upper part of the hopper 11 is pressed to the conveyor belt 14, a guiding casing 18 for unloading the purified dispersed material.

The device operates as follows. Air is supplied to the steam boiler 1 with a fluidized bed furnace 2 by means of a fan 3, whereby a fluidized bed is formed. Then, using a pump 4, a crane 5, oil products 30 are supplied from the vessel 6 to the fluidized bed, which are poured into the vessel 6 before starting the unit. Next, the furnace is ignited from the electric lighter and, using the valve 7, water is supplied to the steam generator 9 from the vessel 8. In the steam generator 9 35, water vapor is generated, which is sent via a crane 10 to the hopper 11. At the same time, with the help of a knife 12, a conveyor 13, dispersed material 15 is fed onto the conveyor belt 15. The dispersed 40 material 15 is transported on the conveyor belt 14 to the steam pumping zone. Moving between the pressure rollers 16, the material falls under the bell, which is pressed onto the conveyor belt by hydraulic 17. The water vapor and gas-vapor mixture (a mixture of gases from the furnace and steam) are blown through a layer of material, heats it and displaces oil products into a container 6 through a permeable (fabric) transport belt 50 ra 14. From tank 6, a mixture of petroleum products and condensate is fed for combustion to the furnace. The cleaned material 15 moves to the discharge zone 18.
