Description

[0001] The invention relates to water purification and can be used in the purification and removal of oil products and suspended bottom sediments in the coastal zone of rivers, lakes and seas.

[0002] A disc oil skimmer is known (Patent for invention of the Russian Federation No. 2052576, IPC F02B 15 / 00, publication 01 / 20 / 1996).

[0003] The oil skimmer's design features a propeller whose rotation and angular movement are synchronous with the disc shaft's rotation, increasing the amount of oil delivered to the disc shaft's working area. This increases the skimmer's performance and the efficiency of oil removal from the reservoir.

[0004] The disadvantage of this installation is that in the presence of highly viscous oil or petroleum products, more thorough water purification is required, as well as the inability to collect heavy fractions from the bottom of the reservoir.

[0005] A device is known - a mobile complex for cleaning soils and reclaiming soils and arable lands from oil pollution (Patent for Utility Model of the Russian Federation No. 143136, IPC E01C23 / 08, published on July 20, 2014).

[0006] This mobile multifunctional unit for cleaning soil and reclaiming arable land from oil spills, adopted as a prototype, consists of a base vehicle with equipment installed on it, including a loading tank / mixer and a cleaning solution tank with a separator for separating the cleaning solution from oil products. Additionally, a milling unit is installed on the base vehicle for cutting oil-contaminated soil and transporting it via a pipeline to the loading tank / mixer, which has a built-in mass transfer device for intensifying the cleaning process and a pump connected to the cleaning solution tank via a closed-loop circuit with a separator and mixer for separating the cleaning solution from oil products.

[0007] The disadvantages of the prototype are: the complexity of the design for collection, the lack of mobility, the lack of heating of water with bottom sediments to 60 degrees to reduce the viscosity of heavy fractions, as well as the rapid transportability of the installation.

[0008] The technical problem that the claimed invention is aimed at solving is to expand the range of cleaning the water surface and bottom of reservoirs from solid fractions of oil or oil products, as well as to increase mobility and reduce the time for assembly and cleaning of the device.

[0009] The stated task is achieved in that in the device for cleaning the water surface of the coastline from oil products, containing a movable platform located on the coastline, a suction pipeline with an ejector nozzle and a pump unit with a pipeline for supplying liquid, according to the invention, a hydrocyclone separator is additionally installed, in which, using electric heating elements, the liquid is heated to 60 ° C to reduce the viscosity of oil or oil products for the purpose of cleaning them from heavy bottom sediments, then the collected material accumulates inside the collection chamber of the hydrocyclone separator, which is equipped with a load sensor, as well as a window for cleaning, while oil-containing water through a pipeline through a booster pump enters the coalescent separator, where the separation of oil or oil products from water occurs, with the subsequent return of purified water to the reservoir through the outlet pipe and the collection of oil or oil products in a collection tank.The general appearance of the device is shown in Fig.

[0010] The device for cleaning the water surface of the coastline from oil products contains: a movable platform 1, which is located on the coastline, an ejector nozzle 2 with a suction pipeline 3, a pump unit 4, a pipeline 5 connecting the pump unit 4 with a hydrocyclone separator 6, electric heating elements 7, a collection chamber 8, a cleaning window 9, a loading sensor 10, a pipeline 11 with a booster pump 12 connecting the hydrocyclone separator 6 with a coalescent separator 13, an outlet pipe 14 connecting the pipeline 15, a collecting oil tank 16.

[0011] The device operates as follows: the device is located on a movable platform 1, which is located on the coastline, where contaminated water with bottom sediments is captured by an ejector nozzle 2 using a suction pipeline 3, suction occurs due to a pump unit 4, while through a pipeline 5 the mixture enters a hydrocyclone separator 6, where, using electric heating elements 7, the liquid is heated to 60 ° C to reduce viscosity.

[0012] The hydrocyclone separator separates water from heavy impurities. The heavy impurities then enter collection chamber 8, where load sensors 10 are installed and triggered when full. Cleaning window 9 then opens. After removing heavy impurities, water flows through pipeline 11 via booster pump 12 to coalescing separator 13, where water is separated from oil products. Oil products are then sent via pipeline 15 to collection tank 16, and purified water is returned to the reservoir through outlet pipe 14.

[0013] Thus, a technical result is achieved: an expanded range of cleaning water surfaces and bottom sediments from heavy oil and petroleum products, increased mobility, and reduced assembly and cleaning time. This device solves the problem of cleaning water surfaces and bottom sediments, reducing the time needed to contain an accident, significantly expanding its applicability for various purposes. The invention can be used in industrial accident response, such as oil and petroleum product spills, as well as in environmental programs for collecting solid materials from water surfaces and bottom sediments.
