Description

The invention relates to the protection of the environment and is intended for the purification of water from any oil products without the use of any chemical reagents.

A device is known for purifying water from oil products, containing a sealed container communicating with each other through an opening closed by a locking device with a device for pouring water and a device for draining oil products and a receiving tank with inlet and outlet devices, respectively, for the entry of contaminated water and the exit of clean water and with a device for the formation of the curvilinear movement of contaminated water (see RF patent No. 2116258 of July 27, 1998).

A disadvantage of the known device is the insufficient efficiency of water purification from oil products, due to the small passage section of the input device, which reduces the performance of the cleaning process.

The technical result to which the invention is directed is to eliminate the above drawback.

This result is achieved by the fact that in the device for water purification from oil products, containing a sealed storage tank communicating with each other through an opening blocked by a locking device with a device for pouring water and a device for draining oil products and a receiving tank with inlet and outlet devices, respectively, for the supply of contaminated water and clean water outlet and with a device for the formation of curved motion of contaminated water, a device for the formation of curvilinear motion contaminated water is in the form of channels formed unclosed cylindrical baffles arranged one inside the other, with a space defined inside the partition, communicated to the output device.

The shut-off device may include a valve with a fully communicating reservoir and via the pipe — with a limited internal partition space, and a valve connected to the actuator located in the cavity of the valve with the possibility of lifting and closing the pipe.

The output device can be made in the form of a pipe bent in the vertical plane with an air fitting, the inlet part of the receiving tank located on the bottom. Unclosed cylindrical partitions can be aligned and in the base can be in the form of an open circle or oval.

Known locking device for cleaning water from oil products, containing a valve that closes the hole, communicating between a receiving and storage capacity (see the previously mentioned patent).

A disadvantage of the known device is the lack of effectiveness, because the exchange of water and oil products between containers occurs only through one hole, which leads to a collision of water particles and oil products with each other and slows down the process of water purification.

The technical result to which the invention is directed is to increase the efficiency of the water treatment process by passing particles of water and oil products mainly through separate openings (channels).

The specified result is achieved by the fact that in the shut-off device of the device for purifying water from oil products, containing a valve blocking the opening communicating between the receiving and storage capacities, the valve is made with a cavity in communication with the storage capacity and by means of a pipe with a receiving capacity in the valve cavity a valve connected to the actuator is arranged, which is capable of blocking the pipe and raising the valve with the cavity.

There is a method of preparing for operation a device for purifying water from oil products, according to which a cycle is carried out containing the following sequential operations: disconnect the receiving and storage tanks, fill the storage tank with water, seal the storage tank and communicate the tanks with each other (see RF patent No. 2116258 07/27/98).

The disadvantage of this method is the low efficiency of the device for water purification from oil products due to incomplete filling of the storage tank with water.

The technical result, which the proposed method is aimed at, is to eliminate the above drawback.

This result is achieved by the fact that in the method of preparing for operation of the device for purifying water from oil products, which carry out a cycle containing the following sequential operations: disconnect the receiving and storage tanks, fill the storage tank with water, seal the storage tank and communicate the tanks with each other, repeat cycle at least one more time.

The invention is illustrated by drawings. Figure 1 schematically shows a device for purifying water from petroleum products, a longitudinal section; figure 2 - section AA - figure 1.

The device (figure 1) consists of a receiving tank 1 and a storage tank 2. The receiving tank 1 is made in the form of a cylinder and has an intake part 3 with a partition 4. The upper part of the partition 4 is located above the opening 5 of the receiving tank. Inside the receiving tank 1 with support on the bottom 6 are partitions 7 with openings 8 and 9 located relative to each other in diametrically opposite directions. Moreover, at the first partition 7, the opening 8 is located on the opposite side of the intake part 3. The partitions 7 are made in the form of cylinders of different diameters, located with gaps between themselves and the walls of the receiving tank 1. As a result, two semicircular channels are formed, dividing the total flow into components with periodic alternation separation and connection thereof with a general movement to a drain pipe 10 containing at the top an air fitting 11 that does not allow the contents to be drained from the installation in cases of interruption of supply liquid. This ensures an increase in the length of the flow path at its optimal speed, uniformity of the high-speed flow, and, consequently, an increase in the time for ascent of oil products of different specific gravities.

The top of the receiving tank 1 is made in the form of a cone 12 with a seat 13 for the valve 14 with a cavity. The valve 14 of the storage tank 2 contains a receiving tank 1 passed through the seat 13, a pipe 15, a seat for a valve 16 located inside the valve (the seat is not shown), a series of holes 17 for communicating with each other through the pipe 15 of the cavities of the storage tank 2 and the receiving tank 1. The valve 16 holds valve 14 with a rod 18 with a movably fixed threaded part with a locking element 19 with a flywheel 20. To fill the installation with water, a hole in the fitting 21 is hermetically closed by a cover, and for draining oil products from the storage tank 2, a drain device with crane 22.

Preparing the device for work

Fill the device with water. To do this, pour contaminated water into the intake part 3. Water through the partition 4 fills part of the receiving tank 2 to the water level of the intake part 3. Rotate the flywheel 20 of the rod 18 with valve 16 and valve 14 to close the hole of the seat 13. The valve 22 is closed and the opening of the fitting 21 is accumulative capacity 2 open. A storage tank 2 is filled through the hole 21 with contaminated water. The opening of the fitting 21 is closed. The flywheel 20 of the rod 18 opens the valve 16 and the hole of the saddle 13 of the valve 14. Water from the storage tank 2 will pour down through the hole of the seat 13 and fill the receiving tank 2 and its conical part 12. The storage tank 2 is sealed. The flywheel 20 of the rod 18 is lowered to the contact with a seat 13 of the valve 14 and a seat of the valve 16. Through the open hole of the fitting 21 fill the storage tank 2 with water. Close the hole of the fitting 21. Use the flywheel 20 to raise the valve 16, and then the valve 14. The water of the storage tank 2 through the hole of the seat 13 will connect to the water of the receiving tank 1. The device is ready for operation.

Device operation

A mixture of water and oil products is fed, for example, continuously to the intake part 3. Where does the mixture, bypassing the partition 4, go through the passage 5 to the receiving tank 1. The water will drain when the water level between the partition 4 and the passage 5 of the receiving tank 1 rises above the drain pipes 10.

Flowing along the semicircular channels bounded by partitions 7, the mixture of water with oil products will be divided into components. Petroleum products with a lower specific gravity than water will rise and proceed through the hole in the saddle 13 to the storage tank 2, forcing water out of its cavity through the hole of the saddle 13 into the receiving tank 1. Water, respectively, with purified water coming in through the drain pipe 10 at the bottom 6 of the receiving capacity 1 will merge.

The incoming mixture with an increased amount of viscous petroleum products, having reached the opening of the seat 13, will freely proceed to the storage tank 2, since the water displaced by them from the storage tank 2 through the openings 17 of the main valve 14 and through the pipe 15 will proceed to the receiving tank 1 to the drain pipe 10.

When you stop supplying the mixture, the device will be in working condition. The water level in the drain pipe 10 is equal to the water level located between the partition 4 and the passage 5 of the receiving tank 1, and communication with the atmosphere of the drain pipe 10 is through the air nozzle 11.

The discharge of petroleum products from the storage tank 2 can occur with a non-working and working device. To drain the collected oil products from the storage tank, it is necessary to close the hole of the seat 13, for this purpose, by rotating the flywheel 20 of the rod 18, make contact with the seat 13 of the valve 14 and then contact with their seat valve 16. Open the hole of the fitting 21 of the storage tank 2. Oil is drained from the valve 22 storage capacity 2.
