Description

The invention relates to methods for the preparation and pumping of petroleum products from drains and sewers.

A method for the preparation of oil sludge emulsions according to RU 2116106 is adopted as an analog.

The disadvantages of the known technical solutions include the low productivity of the process of transporting refined oil sludge.

The new technical solution is aimed at increasing the technological capabilities of the method of preparation and transportation of oil sludge, taking into account factors accelerating the process.

This object is achieved in that in a method for preparing oil sludge for transport, including preparing oil sludge in a drainage accumulator, equipping a drainage accumulator with a filter-heat exchanger, compressor, electric boiler and circulation pump using a lifting mechanism of an oil sludge, the heated antifreeze is fed directly into the zone filtration of oil sludge located in a drainage tank, heated to 90 ° C oil sludge is fed to the production line under pressure up to 1 MPa per With a washer of discrete sludge supply to the production line (11) at a maximum height of a liquid column of up to 9 m, a thickened sludge is removed from the top of the process tank for re-filtration and selection of sludge into the process tank using a tracking float system; for cleaning the filters, the discrete sludge pump is switched off .

The drawing shows a layout of equipment for implementing the method of operation of a sludge device.

Industrial utility of a new technical solution.

The problem of oil sludge treatment is involved in a fairly large number of specialists in the world. A few years ago, this problem was of little concern to anyone, and only now, after many environmental disasters, society began to strive for environmental protection of the earth and water surface from the ground covering with oil products. Real devices began to arise with the help of which people could protect the amphibious surface covered with oil sludge. The proposed method of preparing oil sludge for transport has found application in several regions of the Samara region. The new method is based on the use of special devices capable of accumulating refining and pumping refined oil into containers or mobile vehicles.

The economic efficiency of the new development carries with it the possibility of improving approaches and technological methods for the cleaning of contaminated areas.
