Description

The utility model relates to the field of environmental protection and is intended to clean the surface of water bodies from oil and oil products.

A device is known for removing oil from the surface of the water, containing a floating barrier mounted at an angle to the axis of the river, a spillway with a chamber connected by a channel to a reservoir for collecting oil, and before the spillway, hydraulic resistance elements made in the form of vertical rods are installed below the spillway (author's USSR certificate N 874861, class Е02В 15/10, published on 10/28/81).

A disadvantage of the known device is the inefficient operation of the hydraulic resistance elements installed before the spillway to reduce the flow of water into the chamber, which leads to the collection of oil with a large amount of water and the need for additional separation of oil and water, i.e. increases the operating costs of this device due to additional technological operations and the involvement of additional staff.

Also known is a device for cleaning watercourses from floating contaminants, including a barrier installed in the river channel with a through hole, a spur located outside the fence, adjacent to it and installed perpendicular to the direction of flow, a collecting tank communicating through the through hole in the barrier with a drain a tray having an L-shape and installed with the possibility of vertical movement, and the top of the vertical wall of the tray protrudes above the surface of the water, and for The second through-hole is arranged to divert the water located in the lower part of the collection tank back to the watercourse in the barrier in its lower part, located downstream of the aforementioned first through-hole (patent of the Russian Federation N 2026474, CL ЕВВ 15/04, published on 10.01. 95).

The disadvantages of the known device: the ability to place the collection tank only on the concave bank of the river, low efficiency of water drainage from the bottom of the collection tank back to the watercourse, due to the low negative pressure that occurs when the main stream flows around the spur and acts outside the fence in the area of the second through hole in it , which reduces the performance and overall performance of the entire device.

The closest to the claimed technical solution in terms of the essential features is a system for automatically capturing and collecting contaminants floating on the surface of the river, mainly oil and oil products, containing a boom mounted at an angle to the direction of the river flow, a receiving device located at the bottom end of the river barriers, a settling tank hydraulically in communication with a receiving device, and a discharge device for draining treated water from the bottom tstoynoy container back into the river downstream of its downstream location of the receiving device (U.S. Patent N 3,815,742, cl. E02V 15/04, published 11.06.74).

The disadvantages of the known system: the lack of a mechanism for regulating the volume of contaminated water taken for treatment, depending on the thickness of the contaminated top layer and the lack of a quality control mechanism for treatment, which together does not allow for high-quality water treatment.

The task was set to provide the ability to control the volume of water withdrawn for treatment, depending on the thickness of the contaminated top layer, as well as the ability to control the quality of treatment, which together will ensure high-quality water treatment.

The problem is solved due to the fact that in the device for cleaning the surface of water bodies from oil and oil products containing a receiving device, a settling tank hydraulically connected to a receiving device, and a discharge device for draining purified water from the bottom of the settling tank back to the reservoir, a receiving device made in the form of a pipe with holes provided with a float, and with the possibility of rotation around its axis and fixing the position, it additionally includes a pump installed between the receiving a device and a settling tank and an automatic machine for controlling the processes of collecting contaminated water, sludge and its discharge, and the settling tank is equipped with a drain valve and sensors for the upper and lower levels of contaminated water.

The implementation of the receiving device in the form of a pipe with holes, and equipped with a float, as well as with the possibility of rotation around its axis and fixing the position, allows you to adjust the volume taken to clean the contaminated water, thereby ensuring optimal loading of the cleaning system.

The presence in the device of a pump installed between the receiving device and the settling tank and an automatic machine for controlling the processes of collecting contaminated water, sludge and its discharge, as well as supplying the settling tank with a drain valve and sensors for the upper and lower levels of contaminated water, allow controlling the quality of water treatment.

Together, the essential features make it possible to ensure high-quality water purification.

The claimed technical solution is illustrated by the attached diagram.

A device for cleaning the surface of water bodies from oil and oil products contains a receiving device 1, made in the form of a pipe with holes and provided with a float, and with the possibility of rotation around its axis and fixing the position, a pump 2 installed between the receiving device 1 and the settling tank 3. The device includes includes an automatic machine 4 for controlling the processes of collecting contaminated water, sludge and its discharge, as well as a collection of 5 petroleum products. The settling tank 3 is equipped with a drain valve 6 with a discharge device installed in its lower part, sensors of the upper and lower, respectively, levels of contaminated water (the discharge device and sensors are not shown in the diagram).

The device operates as follows.

The receiving device 1 mounted on the float is placed in a polluted pond and by turning the pipe around its axis the desired position of its holes is established in relation to the water surface being cleaned and the position of the pipe is fixed (when the pipe is in position when its holes are on top, the receiving device is closed, when the position of the pipe, when the holes are completely immersed in water, the maximum intake of purified water occurs). A pump 2 is turned on, which pumps the collected contaminated water into the settling tank 3 until the collected mass reaches a certain level (an upper level sensor is installed in the sump, which responds only to water, but does not respond to oil products), the machine works 4 controls and the supply of contaminated water stops (automatic control stops the supply of electricity to the pump).

Then, over time, (set by the control unit), sludge is carried out and a natural separation of water and oil products occurs (due to the difference in densities). After the sludge time has elapsed, pure water is discharged into the reservoir through the drain valve 6, which is opened by the automatic control unit.

When lowering the liquid level in the settling tank 3 to a certain value (determined by the sensors of the lower level), the control unit closes the drain valve 6 and again supplies the supply voltage to the pump 2.

The polluted water is again pumped into the settling tank, and the oil products collected earlier are on its surface, since their density is much lower than the density of water. This process occurs until a new portion of the collected liquid reaches the upper level, while the oil products (located on the surface) are discharged through the drain hole into the collector 5 (since the sensor, the upper level, does not respond to them).

At the same time, a new process of sludge of collected, contaminated water continues. After that, the operation processes of the device are automatically repeated and occur continuously (the operation of the entire complex is monitored by a control automaton 4 using sensors of the upper and lower levels).

The entire complex can be installed on a watercraft moving along a polluted reservoir. When collecting contaminated water on a narrow river, a receiving device can be installed across the entire width of the river.

Thus, the proposed device for cleaning the surface of water bodies from oil and oil products, allows you to adjust the amount taken to clean the contaminated water, depending on the thickness of the contaminated top layer and automatically control the quality of treatment, which together allows for high-quality water treatment.

The device meets the conditions of industrial applicability and can be manufactured on standard equipment using previously developed technologies.
