Description

The invention relates to devices for cleaning the water surface from solid materials, as well as from oil products on the water surface, can be used for industrial purposes and the elimination of environmental pollution.

Known device "Hydrocyclone sump" patent No. 969286, authors Nikulin V.M., Kabotyansky A.Ya., Oleshko B.I. Published: 10/30/1982, selected as an analogue. The invention relates to facilities for mechanical wastewater treatment and can be used for the treatment of rain and melt water discharged from the sites of industrial enterprises, as well as for the treatment of storm water together with industrial effluents in a combined water disposal system.

The hydrocyclone-settler consists of an outer body with a sludge-accumulating chamber and a peripheral chute protected from above from the ingress of floating substances, a central shaft, a centrifugal clarification chamber formed by the wall of the central shaft and a cylindrical partition with an expanding socket, which forms a gravitational clarification chamber with the outer body . A branch pipe for a tangential supply of wastewater to be treated passes into the centrifugal clarification chamber. A grapple is provided for cleaning the sump, and oil collection devices are used to collect oil. In the upper part of the centrifugal clarification chamber there is a receiving funnel of square section. The funnel passes into a branch pipe, through which storm water drains into a container located outside the sump body. At the end of the branch pipe, which goes into the tank, a mesh box is installed, designed to retain floating impurities. In the lower part of the centrifugal clarification chamber there is a second branch pipe connecting it with the tank and having a locking device. The removal of clarified effluents from the trays is carried out through a pipeline with a shut-off device.

A hydrocyclone-sump containing a housing, coaxially arranged partitions forming chambers for centrifugal and gravitational clarification, a tangential branch pipe for supplying clarified waters and a peripheral catchment tray, characterized in that, in order to ensure efficient operation of the sump under conditions of uneven inflow of storm water, it is equipped with an additional external tank, a receiving funnel with a storm water drain pipe installed in the centrifugal clarification chamber, a mesh box installed in an additional tank under the storm water drain pipe and a flow pipe connecting the lower parts of the centrifugal clarification chamber and additional tank. The hydrocyclone-sump is characterized by the fact that the body is made with a square section.

The disadvantage of the device is: stationary use, no mobility of the device, the difficulty of cleaning the sump.

Known device "Device for the accumulation and purification of rainwater "Renols"" patent No. 992210, authors Volkov R.F., Mineev E.K., Zotov N.I. Published: 09/30/1982, selected as a prototype. The device belongs to facilities for cleaning liquids containing suspensions, including oil products, and can be used at industrial sites in all sectors of the national economy for the treatment of rain and melted wastewater.

It consists of sections of a settling tank with an artificial base equipped with a drainage device, a zone of preliminary clarification of rainwater, oil and oil removal devices, blocks of inclined plates (or cellular structures, flotation chambers equipped with tubular aerators; overflow and emptying (M) pipes, a waste-retaining grate , branch pipes supplying wash water, lamp wells, branch pipes supplying storm water to the receiving chamber of the rain runoff, branch pipes discharging rainwater, entry devices from quickly dismantled blocks.

A device for accumulating and treating rainwater, includes a preliminary clarification chamber, oil skimmers and oil gathering devices, inlet, distribution, drainage and outlet pipelines with shut-off and control equipment, a flotation chamber with overflow pipes, a sectional sump and inclined plates installed with a gap, which differ in that that, in order to improve the efficiency of rainwater treatment, the device is equipped with a receiving chamber and a debris retaining grate placed in it, the flotation chamber is made in the form of trays communicating with the sections of the sump, overflow pipes are equipped with aerators in the lower part, the bottom of the device is zigzag-shaped and equipped with placed at the tops of the zigzag bottom with drainage filtering devices, while the plates are installed between the pre-clarification and flotation chambers.

The disadvantage of the prototype is: stationary use, lack of mobility of the device, large dimensions.

The purpose of the invention is to expand the range of cleaning the water surface from solid materials, increase the mobility of the device, reduce the time for installation, assembly and cleaning of the device.

To solve the problem, the device for cleaning from the water surface contains: a frame structure 1, ballast 2 to maintain this installation in a floating state, lifting ears 3 for transporting the installation, a cylindrical removable mesh 4 for collecting solid materials, a housing for a removable mesh 8, a rod - grid load sensor 5, water outlet manifold 6, pressure sensor 7 on the outlet manifold, pipeline 9, pump 10, cleaning device 11 (Fig. 1).

The device works as follows: the housing for the removable mesh 8 is fixed by the frame 1 on the ballast 2 to keep the device in a floating state in such a way that the upper part of the housing is flush with the water surface. Water, together with solid materials, sorbents, when the pump 10 is turned on, enters the cylindrical collection grid 4 under the influence of the Coriolis effect, where the solid materials remain in the collection grid. Under the prefabricated mesh there is a loading sensor 5, which determines the degree of loading of the mesh with solid materials, also on the outlet manifold 6, a pressure sensor 7 is installed. After one of the sensors is triggered, the installation stops and the mesh needs to be removed and cleaned. Further, after cleaning from solid materials, contaminated water through the collector 6 enters the pipeline 9 and through the pump 10, the contaminated water enters the filter 11 (the filter is connected to your choice depending on the pollution of the water surface).

With this method, rapid water purification is provided, both from solid materials and biological pollution.

Thus, this device solves the problem of cleaning the water surface and reduces the localization time in case of an accident on the water surface, which significantly expands the range of application of this device for various purposes.

This device can be used both in industry in the aftermath of accidents, for example, spills of oil and oil products on the water surface when using absorbent materials (rubber crumb, biosorbents), and in environmental programs for the collection of solid materials from the water surface.
